    JUSTICE BURKE delivered the judgment of the court, with opinion.
    Presiding Justice McBride and Justice Ellis concurred in the judgment and opinion.
    OPINION
    ¶1      Following a bench trial, the circuit court entered judgment in favor of defendant Quarles
    & Brady in this legal malpractice claim. The claim was predicated on Quarles & Brady’s
    representation of plaintiff Kenneth Nelson in the federal district court in his suit against his
    former business partner in two automobile dealerships (the “Underlying Litigation”). The district
    court ruled against Nelson, but that decision was reversed on appeal by the Seventh Circuit Court
    of Appeals. Rather than pursue further litigation in the federal court on remand, the parties
    settled, and Nelson subsequently filed this legal malpractice action against Quarles & Brady. The
    circuit court found that Nelson had failed to establish that Quarles & Brady’s representation
    No. 1-17-1653
    deviated from the standard of care or that Quarles & Brady’s representation proximately caused
    him any damages. For the reasons that follow, we affirm the judgment of the circuit court.
    ¶2                                     I. BACKGROUND
    ¶3                                A. The Underlying Litigation
    ¶4              1. Nelson and Curia’s Written Agreements and Stock Purchase Options
    ¶5     Prior to 1989, Nelson was the sole shareholder in two automobile dealership
    corporations: Ken Nelson Auto Plaza, Inc. (Plaza), located in Dixon, Illinois, and Ken Nelson
    Auto Mall, Inc. (Mall), located in Sterling, Illinois. The two dealerships carried vehicles from
    Toyota, General Motors (GM), Nissan, and Chrysler. In 1989, Nelson hired Richard Curia as
    general manager, and the two entered into a stock purchase agreement (1989 SPA) whereby
    Curia would be able to acquire a 100% ownership interest in both corporations pursuant to a
    series of options. Under the 1989 SPA, Curia would initially pay $100,000 for 1000 shares in
    Plaza and 144 shares in Mall. The 1989 SPA also provided Curia with options to purchase
    additional shares. The first option permitted Curia to purchase an additional 1000 shares of Plaza
    and 144 shares of Mall for an additional $100,000. Under the second option, Curia could
    purchase 2009 shares of stock of Plaza and 300 shares of Mall, “which shares with previous
    purchased shares would represent 49% of the issued and outstanding shares of capital stock in
    said corporations.” This option provided a formula for the purchase price of these shares, which
    was based on the corporations’ net worth, accumulated depreciation, “LIFO (last in first out)
    reserve,” and the total number of shares in each corporation. To determine the metrics for this
    formula, the parties would reference the monthly operating reports issued by GM and Nissan.
    ¶6     The third and final option provided that “[a]fter exercising the first two options to
    purchase as provided in this Agreement, [Curia] shall have a third option to purchase from
    -2­
    No. 1-17-1653
    [Nelson] the remaining 4,171 shares of stock in [Plaza] and 612 shares of stock in [Mall]
    provided that [Curia] also offer to purchase the land and four buildings of the [Plaza] dealership
    *** at its appraised value.” The third option also provided that the purchase price of the shares
    would be based on a valuation formula similar to the formula outlined in the second option. The
    1989 SPA required Curia to provide written notice of his election to exercise each option.
    ¶7     In 1993, Nelson and Curia entered into another agreement intended to modify the 1989
    SPA (1993 Modification). The 1993 Modification provided that “a mutual mistake of fact was
    made by Nelson and Curia in determining the fair market value of the capital stock of [Plaza and
    Mall.]” The 1993 Modification was therefore intended to “modify the [1989 SPA] to reflect the
    re-evaluation of the minority interest *** and to correct the mutual mistake of the parties.” The
    1993 Modification also included a new formula for calculating the price of the shares Curia
    could purchase from Nelson. Paragraph 5 of the 1993 Modification was titled “Purchase of
    Additional Shares” and provided that:
    “Curia shall have the right to purchase additional shares of stock in said
    corporations upon those terms and conditions subsequently agreed upon by the parties
    hereto. The purchase price for said additional shares of stock shall be determined by
    adding to the total net worth of each corporation a figure representing the accumulated
    ‘LIFO’ (last in first out) reserve and dividing the total sum thereof by the number of
    shares of each corporation.”
    Nelson testified that in entering into this modification, he and Curia intended to eliminate the
    options contained in the 1989 SPA, and that they had the understanding that if Curia wanted to
    purchase additional shares, they would be required to enter into a separate agreement. Curia
    testified that, at the time they entered into the 1993 Modification, he did not understand what the
    -3­
    No. 1-17-1653
    word “subsequently” meant in the first sentence of the Purchase of Additional Shares section.
    Curia testified that the 1993 Modification was not intended to eliminate the 1989 SPA options
    and that he believed that the 1993 Modification, in conjunction with the options in the 1989 SPA,
    would permit him to purchase all of Nelson’s shares. He testified that the parties entered into the
    1993 Modification because he believed he had paid too much for the shares he received in the
    1989 SPA.
    ¶8        The parties entered into subsequent written agreements in 1997 (1997 Harkness
    Agreement) and 2000 (2000 Agreement). The 1997 Harkness Agreement was drafted when
    Harkness purchased shares of Mall in 1997. The 1997 Harkness Agreement provided that it
    “supersede[d] all prior agreements and understanding between Nelson and Curia referring to
    future purchases of stock of [Mall.]” Harkness subsequently left Mall, and Mall repurchased his
    shares.
    ¶9        In 2000, Nelson and Curia entered into another agreement (2000 Agreement), titled
    “Amendment to Modification Agreements.” The 2000 Agreement was drafted, at least in part, to
    delineate Curia and Nelson’s intent with respect to the transfer of shares if either of them died.
    The 2000 Agreement also provided that Nelson and Curia “had previously entered into [the 1989
    SPA] and [the 1993 Modification],” and copies of both were attached as exhibits. The 2000
    Agreement provided that if Nelson died while the 1989 SPA and 1993 Modification were “in
    force,” Curia must immediately purchase from Nelson sufficient shares in Plaza to make Curia
    the majority shareholder. The 2000 Agreement also set out another formula for the purchase
    price of those shares and Nelson’s remaining shares, which differed from the formula in the 1989
    SPA and 1993 Modification. The 2000 Agreement provided that it was “not a new modification
    agreement, but an amendment to the [1989 SPA] and the [1993 Modification].”
    -4­
    No. 1-17-1653
    ¶ 10   In 2002, Nelson and Curia formed CRANK, LLC (CRANK), which owned all of the real
    estate used by the two dealerships. Nelson and Curia each owned 50% of CRANK.
    ¶ 11                           2. The Stock Purchase Negotiations
    ¶ 12   In 2004, Nelson and Curia began discussions regarding Nelson’s desire to retire and sell
    all of his shares in both Plaza and Mall to Curia. According to Nelson, in July 2004, Curia agreed
    to buy Nelson’s majority ownership interest in both corporations for $4.2 million. Nelson
    testified that the $4.2 million amount was based on the June 2004 GM financial statement and
    was calculated using the formula in the 1989 SPA. Nelson testified that this was an oral
    agreement and was never memorialized in writing. He contended, however, that evidence of this
    oral agreement was present in (1) corporate resolutions from both corporations’ board of
    directors to accept the agreement, (2) correspondences from both Nelson and Curia with
    automobile manufacturers informing them of the stock purchase agreement and seeking approval
    for the transfer of ownership, and (3) a loan commitment document from Fifth Third Bank (Fifth
    Third) for $4.2 million obtained at Curia’s request. Curia denied ever agreeing to purchase
    Nelson’s shares for $4.2 million.
    ¶ 13                  a. The Directors’ Resolutions and Stockholders’ Minutes
    ¶ 14   On October 6, 2004, Nelson prepared the Minutes of the Annual Meeting of Stockholders
    for Plaza (Stockholders’ Minutes). The Stockholders’ Minutes provided that “Upon motion duly
    made and seconded, it was unanimously RESOLVED, that the following conditions of the sale
    and transfer of stock from [Nelson] to [Curia] be approved by the Board of Directors.” The
    Stockholders’ Minutes then listed nine “conditions.” The first condition provided that the sale of
    the stock would be in accordance with the 1989 SPA. The remaining eight conditions provided
    that (1) the corporation would provide health care to Nelson and his wife for 10 years, (2) the
    -5­
    No. 1-17-1653
    corporation would provide a new vehicle of Nelson or his wife’s choice for 15 years, including
    the dealer license plates, (3) the corporation would provide a second vehicle of Nelson’s choice
    for 10 years, (4) in the event that Nelson or his wife were unable to drive, the corporation would
    provide a driver, (5) the corporation would provide transportation for Nelson and his wife to and
    from the airport and vehicles for when they were “in town” as long as Nelson owned part of the
    properties that the dealership leased, (6) Nelson would have access to monthly GM financial
    statements, (7) the name “Ken Nelson” could be used for the corporation, and (8) a hold
    harmless agreement be written for the protection of Nelson and his family members. Nelson
    testified that these items represented his “retirement package” and were “perks” that he and
    Curia had agreed to after agreeing upon the $4.2 million purchase price. Nelson signed the
    Stockholders’ Minutes, but Curia did not.
    ¶ 15   One day later, on October 7, 2004, Nelson prepared separate Special Meetings of
    Directors documents for Plaza and Mall (Directors’ Resolutions). The Directors’ Resolutions
    provided that “[a] resolution was duly moved and seconded to accept an agreement by the
    stockholders, [Nelson and Curia], that [Nelson] would sell his 8000 shares in this corporation
    (52.7%) to [Curia], and that the manufacturers be contacted to facilitate the transaction.” The
    Directors’ Resolutions further provided that Fifth Third would be funding the capital for the
    stock transfer. The Directors’ Resolutions provided that the manufacturers would be contacted
    because automobile manufacturers require their approval for any transfer of majority ownership
    of a franchised dealership. Both Nelson and Curia signed the Directors’ Resolutions.
    ¶ 16                  b. Communications with Automobile Manufacturers
    ¶ 17   Both Nelson and Curia understood that any change of majority ownership interest would
    have to be approved by the automobile manufacturers. On October 28, 2004, Nelson sent letters
    -6­
    No. 1-17-1653
    to the automobile manufacturers, informing them that he “proposes to sell” his shares in both
    dealerships to Curia. Representatives from the manufacturers responded, requesting additional
    documentation from both Nelson and Curia, including an ownership change agreement. As
    evidence of an ownership change agreement, Nelson sent the manufacturers the Directors’
    Resolutions. In November 2004, Curia submitted documentation to the automobile
    manufacturers, including the Toyota Minimum Standards, the Toyota Dealer Performance
    Evaluation, Dealer Biographical Information, and an Application for Nissan Dealer Sales and
    Service Agreement.
    ¶ 18                            c. Fifth Third Loan Commitment
    ¶ 19   In September 2004, Curia and Nelson approached Inghram Debes, the relationship
    manager in the automobile dealership finance group at Fifth Third, to request a loan for Curia to
    purchase Nelson’s shares. On November 4, 2004, Debes sent a letter to Curia to “confirm that
    Fifth Third Bank has approved and is committed to lend [Plaza] a term loan totaling $4,200,000.
    The purpose of this loan is to provide you with sufficient funds to buy-out [Nelson’s] remaining
    ownership interest in [Plaza and Mall].” Curia testified that this letter was necessary to show the
    automobile manufacturers that he could secure the funds to proceed with the buyout.
    ¶ 20            3. Breakdown of Negotiations and Curia’s Option Exercises
    ¶ 21   On October 26, 2004, Nelson sent Curia a document entitled “Chronology of [Nelson]
    and [Curia] Stock Purchase” (Chronology). Nelson testified that he prepared this document after
    he learned that Curia was “balking” on the leases and the items in the Stockholders’ Minutes. In
    the Chronology, Nelson recounted their business partnership, including the 1989 SPA and 1993
    Modification. Nelson stated that:
    -7­
    No. 1-17-1653
    “My offer to have you buy me out at this time was with great consideration for
    you. We have a bank ready and able to handle the transaction for you at very good
    interest rates. However, I didn’t believe that you would be so difficult in extending to me
    things that I really need for retirement; and to this date you have not come up with a
    retirement package for me.
    ***
    I will be calling the manufacturers; however, as I told you when I was in earlier
    this month, there is no reason for me sending any letters of my wish to sell until we have
    a package put together.”
    ¶ 22   On November 4, 2004, Curia responded to the Chronology. In response to Nelson’s
    request for a retirement package, Curia responded that he did not “see anywhere in our
    agreement that I was to fund a retirement package.” Curia testified that by “agreement,” he was
    referring to the 1989 SPA and the 1993 Modification. Curia also wrote “please allow this to
    serve as written notice to exercise my option to purchase the remainder of the stock” in Plaza and
    Mall. Curia expressed his desire to close the transaction by the end of the year. On November 3,
    4, and 10, Curia submitted documentation to the automobile manufacturers. On November 4,
    Curia also submitted an Investment Proposal Summary to GM, to which he attached the letter
    from Fifth Third committing to the $4.2 million loan. On November 17, 2004, Debes sent the
    loan documents for the “Curia buy-out” to Toyota and stated that Fifth Third was “ready to fund
    this transaction when instructed by Mr. Curia.” Debes sent the same loan documents to Nissan
    on November 29, 2004.
    ¶ 23   On December 3, 2004, Nelson wrote a letter to Curia, offering to sell his shares in Plaza
    and Mall for $3.4 million, using calculations based on the September 2004 GM financial
    -8­
    No. 1-17-1653
    statement. On December 21, 2004, Nissan sent a letter to Nelson and Curia, informing them that
    it had approved the proposed stock purchase agreement conditioned on the receipt of several
    documents from both the corporations and Fifth Third. On February 28, 2005, Curia wrote an
    email to Nelson, in which he stated that he “had more than one attorney review our agreements,
    and they all have the same conclusion. All we are asking you to do is honor our agreements.”
    ¶ 24   On March 2 and 3, Curia sent Nelson a “Notice of Exercise of Option” for both Mall and
    Plaza (Option Exercises). In the March 2 Option Exercise, Curia stated that he had previously
    exercised his first option under the 1989 SPA. Curia stated that the second option gave him “the
    right to purchase from you an additional number of shares of capital stock of [Plaza] and [Mall]
    that would give me 49% of the outstanding capital stock of each Corporation.” Curia stated that
    he calculated that to be 193 shares of Plaza and 170 shares of Mall. Curia notified Nelson that he
    was exercising his option to purchase those shares in accordance with the terms of the 1989 SPA
    and the 1993 Modification. In the March 3 Option Exercise, Curia stated that he was exercising
    the third option under the 1989 SPA to purchase Nelson’s remaining shares in Plaza and Mall
    and Plaza’s land and four buildings.
    ¶ 25                          4. Nelson Retains Quarles & Brady
    ¶ 26   On March 8, 2005, Nelson sent a letter and a packet of documents to Kimberly Johnson,
    an attorney at Quarles & Brady’s Naples, Florida office who had previously worked on Nelson’s
    estate planning. In the letter (Johnson Letter), Nelson informed Johnson that in September 2004,
    he approached Curia about purchasing his stock in the corporations. Nelson stated that he gave
    Curia some conditions for the purchase, including to meet the selling price set forth in the 1989
    SPA based on the September 2004 GM financial statement. Nelson also stated that the agreement
    was conditioned upon Nelson receiving vehicles from the dealership with insurance, health
    -9­
    No. 1-17-1653
    insurance for him and his wife, transportation to Dixon, Illinois to inspect buildings, hold
    harmless agreements, and access to GM financial statements. Nelson further stated that he and
    Curia met in January 2005 and realized that they were not in agreement with either the purchase
    price or “its application.” Nelson stated that in January and February they met with brokers in an
    attempt to sell the dealerships to a third party, but were unable to choose a broker. Nelson then
    received the letters from Curia, informing him of his intent to exercise his options.
    ¶ 27      Nelson stated that under the written agreements, Curia could exercise his options to
    purchase only if he and Nelson mutually agreed or if one of them died. Nelson stated that “it was
    expressly understood that there would be no sale unless it was mutually agreed to and beneficial
    to both shareholders.” Nelson attached to the Johnson Letter the 1989 SPA, the 1993
    Modification, the 2000 Agreement, the October 26, 2004, Chronology with Curia’s response, the
    unsigned October 6, 2004, Stockholders’ Minutes, Curia’s February 28, 2005, email in which
    Curia asked Nelson to honor their “agreements,” Nelson’s response to that email on the same
    date, and Curia’s March 2 and 3, 2005, Option Exercises (Johnson Packet). Johnson referred
    Nelson to James Gatziolis, a partner and transactional lawyer in Quarles & Brady’s Chicago
    office.
    ¶ 28      On March 13, 2005, Nelson sent a draft of his response letter to Curia’s Option Exercises
    to Gatzilios. In the draft letter, Nelson stated that Curia’s Option Exercises had not met the
    conditions of the 1993 Modification. Nelson specifically pointed to the language in the 1993
    Modification that provided that any sale of stock would be based “upon those terms and
    conditions subsequently agreed upon by the parties.” Nelson further stated in August 2004, he
    offered Curia the opportunity to purchase his stock in Plaza and Mall “upon certain terms and
    conditions” which were set forth in a letter Nelson left on his desk on December 3, 2004. Nelson
    - 10 ­
    No. 1-17-1653
    represented that those terms and conditions were that the October 6, 2004, Stockholders’
    Minutes be signed by both parties, that the newly agreed leases for the properties owned by
    CRANK be signed by both parties, and that the September 30, 2004, GM financial statement be
    used for the sale price. The draft letter was revised by Gatziolis, then further revised by Nelson,
    and sent to Curia on March 14, 2005.
    ¶ 29   On March 29, 2005, Nelson sent a letter to Gatziolis, representing that he made his first
    offer to have Curia purchase his shares in July 2004. On April 20, 2005, Nelson, his wife Carol
    Nelson (Carol), and his son Korey Nelson (Korey) met with Gatziolis at the Quarles & Brady
    Chicago office. Carol took notes at the meeting, but at trial was unable to explain what the
    context of her notations meant outside of the words on the page. Carol wrote mostly in
    unattributed shorthand phrases such as “Any other conditions would be: formula for stock
    price—June 2004” and “Get this deal behind you!” After the meeting, Gatziolis brought Leonard
    Shifflett, a litigation attorney at Quarles & Brady, onto the case to handle the litigation.
    ¶ 30                           a. The Declaratory Judgment Complaint
    ¶ 31   On April 29, 2005, Quarles & Brady filed a complaint, on Nelson’s behalf, for
    declaratory relief in the United States District Court for the Northern District of Illinois. The
    complaint provided that, in July 2004, Nelson approached Curia about purchasing Nelson’s
    shares in the dealerships, but the parties could not reach an agreement about the terms and price.
    Quarles & Brady alleged that Curia’s March 2 and 3, 2005, Option Exercises were defective
    because the 1993 Modification and 1997 Harkness Agreement effectively terminated the options
    in the 1989 SPA. The complaint therefore sought a judgment declaring that Curia had no
    exercisable option to purchase Nelson’s shares in the corporations, that Curia’s March 2 and 3,
    2005, Option Exercises were void, and that Curia was in breach of the 1989 SPA, the 1993
    - 11 ­
    No. 1-17-1653
    Modification, and the 1997 Harkness Agreement. Curia filed a separate action in the district
    court seeking specific performance of the options, and the two cases were consolidated.
    ¶ 32                          b. The Summary Judgment Motions
    ¶ 33                       i. Curia’s Motion for Summary Judgment
    ¶ 34   Quarles & Brady and Curia filed cross-motions for summary judgment. In his motion for
    summary judgment, Curia contended that the parties’ written agreements unambiguously
    provided him the right to purchase Nelson’s shares in both corporations and that the price of the
    shares should be $2,269,694.80 based on the formula in the 1993 Modification. Despite arguing
    that the agreements were unambiguous, Curia contended that in Paragraph 5 of the 1993
    Modification, which provided that “Curia shall have the right to purchase additional shares of
    stock in said corporations upon those terms and conditions subsequently agreed upon by the
    parties hereto,” he and Nelson actually intended to use the word “previously,” rather than the
    word “subsequently.” Curia asserted that this construction of the paragraph would allow the non-
    material terms of the 1989 SPA to be incorporated into the 1993 Modification and that Curia
    would have the right to exercise the 1989 SPA options. This construction of the 1993
    Modification would also defeat Nelson’s contention that the 1993 Modification created an
    “agreement to agree.” Curia contended that such a result was logical because Nelson’s
    construction of the written agreement would give Curia a right to purchase the shares, but not the
    opportunity to do so unless Nelson agreed.
    ¶ 35            ii. Nelson’s Communication with Quarles & Brady After Curia’s Motion
    ¶ 36   On July 16, 2005, Nelson sent an email to Shifflett and Gatziolis regarding the 1997
    documents. Nelson stated that he “found the items that go with the letter to David Williamson
    our corporate attorney.” Nelson suggested that Quarles & Brady “ask Mr. Williamson for all of
    - 12 ­
    No. 1-17-1653
    his notes and documents on all of the four agreements that he produced for both [Curia] & I and
    Harkness, which includes the ‘subsequently’ one.”
    ¶ 37   On July 26, 2005, Nelson faxed Quarles & Brady a document entitled “Ken’s Story” in
    response to Curia’s motion. In Ken’s Story, Nelson stated that in July 2004, he offered to retire
    from the corporations, and in September 2004, he presented Curia with an offer to sell his shares
    for $4.1 million. He stated that he and Curia further negotiated and Nelson made another offer on
    December 4, 2004, for Curia to purchase his shares in both corporations for $3.4 million. Nelson
    further provided that “[a]fter again trying to negotiate with Curia through December 2004 it was
    apparent even though Curia had the financing from Fifth Third Bank to make the purchase, he
    was unwilling to come to terms nor even to make a counter offer.”
    ¶ 38   Before filing the summary judgment motion, Quarles & Brady sent a draft of the motion
    to Nelson and Korey for their review. Nelson and Korey sent back an edited version of the
    motion. In a paragraph beginning “[i]n 2004 [Nelson] approached Curia *** about the possibility
    of Nelson selling his majority share of stock in [Plaza] and [Mall]” Nelson and Korey added that
    “Nelson and Curia began negotiating the price and manner of the stock sale,” but “at some point
    Curia began maintaining he possessed” exercisable options. Further, in the statement of facts of
    the motion, Nelson and Korey wrote that in July 2004, Nelson met with Curia and offered to sell
    his shares in the corporations to Curia. They further wrote that, in September 2004, Nelson
    presented an offer to sell his shares to Curia, “but Curia did not accept.” Nelson and Korey
    specifically added language that Curia did not accept Nelson’s September 2004 offer. The
    original draft of the motion also stated that Curia never accepted Nelson’s offer, but Nelson and
    Korey edited it to read that “Curia never accepted any of Nelson’s offers,” changing the word
    “offer” from singular to plural.

    ¶ 39                       iii. Quarles & Brady’s Motion for Summary Judgment
    ¶ 40    On August 3, 2005, Quarles & Brady filed its memorandum in support of Nelson’s
    motion for summary judgment and in opposition to Curia’s motion for summary judgment. In its
    memorandum, Quarles & Brady asserted that a plain reading of the 1993 Modification
    contradicted Curia’s argument that he had a unilateral right to purchase Nelson’s shares pursuant
    to the 1989 SPA. Quarles & Brady contended that, under Paragraph 5 of the 1993 Modification,
    Curia could purchase additional shares only “upon those terms and conditions subsequently
    agreed upon by the parties hereto,” and there was no allegation that the parties ever subsequently
    agreed to any “terms and conditions.”
    ¶ 41    As for Curia’s assertion that the parties intended to use the word “previously” rather than
    “subsequently” in Paragraph 5, Quarles & Brady contended that Curia did not raise this issue in
    his affidavit and his motion merely “suggests” that previously was intended because the next
    sentence of Paragraph 5 established the price for the shares. Quarles & Brady contended that
    Curia’s assertion that “any terms that required later determination would not be material” is
    contrary to Illinois law, which provides that if essential terms are missing or uncertain, then there
    is no contract. Quarles & Brady asserted that the court should reject this contention and enforce
    the contract as written, which required Curia to negotiate with Nelson if he wished to purchase
    shares from him, and if they could not come to an agreement, then either party could sell their
    shares to a third party.
    ¶ 42    Quarles & Brady also argued that the 1997 Harkness Agreement voided the options or
    any rights Curia held under the 1989 SPA and 1993 Modification. Quarles & Brady further
    contended that Curia’s options failed for lack of consideration. In the alternative, Quarles &
    Brady asserted that even assuming Curia had the option to purchase Nelson’s shares, his Option
    - 14 ­
    No. 1-17-1653
    Exercises were deficient because Curia calculated the purchase price under the 1993
    Modification rather than the formula in the 1989 SPA options. Quarles & Brady contended that if
    the court determined that Curia’s Option Exercises were valid, the price of Nelson’s shares
    should be determined by the formula in the 2000 Agreement.
    ¶ 43   Quarles & Brady also drafted an affidavit for Nelson, which repeated much of the same
    information from Nelson and Korey’s edited comments to the motion for summary judgment,
    including that Curia did not accept Nelson’s September 2004 offer and that “Curia never
    accepted any of [Nelson’s] offers” despite having financing from Fifth Third. Nelson signed the
    affidavit, and it was attached to the summary judgment motion.
    ¶ 44                                   iv. Curia’s Response
    ¶ 45   On September 2, 2005, Curia filed an affidavit and a response to Nelson’s statement of
    undisputed facts. In his response, Curia acknowledged that Nelson offered to sell his shares to
    him in July 2004, but Nelson requested a number of provisions including that the corporations
    provide health insurance for Nelson and his wife and new cars for 15 years. Curia contended that
    these demands and the per-share price demanded by Nelson resulted in a purchase price that
    significantly exceeded the prices calculated under the 1989 SPA and 1993 Modification. Curia
    asserted that he did not accept any of Nelson’s offers, but as a courtesy to Nelson, “he listened
    and reacted to every offer Nelson made.” Curia contended that each of Nelson’s offers contained
    the additional provisions from the July offer. In his affidavit, Curia averred that in Paragraph 5 of
    the 1993 Modification, he and Nelson “intended to use the word ‘previously’ rather than the
    word ‘subsequently.’ ”

    ¶ 46    v. Nelson’s Communications with Quarles & Brady Before District Court Ruling
    ¶ 47   On September 17, 2005, Nelson sent an email to Shifflett in which he stated that when he
    went to Curia in July 2004 to retire, he put together a retirement package. Nelson stated that he
    thought it would be fair to have some formula for the basis, so he used a basis that they both
    understood and had agreed to before to negotiate. Nelson concluded that he “was not really going
    to [Curia] with the [1989 SPA] in hand, I was going to him with a package that I felt we could
    negotiate on.” Nelson sent another email to Shifflett and Gatziolis on November 22, 2005,
    indicating that he wanted them to communicate to the presiding magistrate that “we have tried to
    negotiate with [Curia] since July of 2004 and put many offers on the table, but without any
    response to our offers.”
    ¶ 48                             5. The District Court’s Ruling
    ¶ 49   On February 7, 2006, the district court entered its judgment. The district court granted
    Nelson’s motion for summary judgment with respect to Mall, but granted Curia’s motion for
    summary judgment with respect to Plaza. The district court found that there was no indication
    that the 1993 Modification was intended to eliminate the options in the 1989 SPA, but was
    intended to correct a mutual mistake by Nelson and Curia in valuing the stock of the corporations
    purchased by Curia. With regard to the “subsequently” language in Paragraph 5 of the 1993
    Modification, the district court determined that where the sentence following the “subsequently”
    sentence established a method for determining the purchase price of the additional shares, it
    would “def[y] reason (particularly in light of the absence of any expression of intent to change
    Curia’s right to buy all Nelson’s shares) that the parties would provide a mechanism for
    determining the purchase price but intend it to kick in only if they subsequently agreed on other
    terms and conditions.”
    - 16 ­
    No. 1-17-1653
    ¶ 50   The district court further found that the 2000 Agreement further reinforced Curia’s right
    to purchase Nelson’s stock in Plaza where it provided Curia the right to purchase Nelson’s shares
    if Nelson died while the 1989 SPA and 1993 Modification were still in force. The court
    determined that the 1989 SPA, in conjunction with the 1993 Modification and the 2000
    Agreement, unambiguously provided Curia with the option to purchase Nelson’s shares in Plaza
    with the price determined under the formula set forth in the 2000 Agreement.
    ¶ 51   The district court determined, however, that the 1997 Harkness Agreement superseded
    the 1989 SPA and the 1993 Modification with respect to Mall, but not Plaza. Accordingly, the
    district court found that the Mall shares were subject to the 1997 Harkness Agreement and that
    Curia’s Option Exercises were defective with respect to those shares. The selling price of the
    Plaza shares and other issues remained pending in the district court.
    ¶ 52            6. Nelson’s Post-Judgment Communications and Further Proceedings
    ¶ 53   On March 10, 2006, at Nelson’s request, Toyota sent him two “resolution letters and an
    ownership change proposal letter” that had been sent to Toyota on October 28, 2004. This
    included the Special Meetings of Directors document for Plaza on October 7, 2004. Nelson
    forwarded these documents to Gatziolis and told him that (1) he had never received the “letter,”
    (2) to his knowledge, Toyota had never received a “Resolution of the Board” or any ownership
    change agreement, and (3) perhaps Curia had “made these up.” Nelson sent a second email to
    Gatziolis later that day, stating that he “did not have a copy of this directors meeting.”
    ¶ 54   On March 21, 2006, Nelson emailed Julie Thomas at Toyota. Thomas had taken over the
    position of Market Representation Administrator from Samuel Zangri, who had held the position
    in October and November 2004, when Nelson and Curia first contacted Toyota about the
    - 17 ­
    No. 1-17-1653
    ownership change. Thomas replied to Nelson’s email that the “original stock purchase agreement
    included both [Plaza] and [Mall]. The total selling price to our understanding was $4,200,000.”
    ¶ 55   On June 5, 2006, Quarles & Brady filed an amended complaint on Nelson’s behalf,
    alleging once again that Curia did not have an exercisable option to purchase Nelson’s shares in
    Plaza. Quarles & Brady also alleged that Curia had breached his fiduciary duty and
    misappropriated the corporation’s funds. In response, Curia filed a motion for summary
    judgment, asking the court to find that his Option Exercises were valid.
    ¶ 56   On August 29, 2006, Nelson sent an email to Shifflett and Paul Cahill, another attorney at
    Quarles & Brady who had been assigned to work on Nelson’s case, with his comments on
    Curia’s answers. In his comments Nelson stated that he and Curia intended what they wrote in
    the agreements, “not what we now think.” Nelson stated that he initially began negotiations with
    Curia in July 2004 and sent letters to manufacturers at a price he and Curia negotiated and agreed
    to “4.2m (stock only, both corps).” Nelson also noted that there was a letter from Fifth Third,
    showing that it agreed to loan $4.2 million, but it was “then Curia decided that he didn’t want to
    pay much [sic].” Nelson stated that he did not refuse to cooperate, but in September 2004, prior
    to Curia “circumventing” what they had negotiated, he sent letters to the manufacturers,
    recommending the sale. Nelson stated that he and Curia used the 2000 agreement as a “base” and
    then “began adding other perks,” but there was a delay because Curia refused to do what the
    manufacturers demanded. Nelson stated that the delay was also caused by “Curia not seeking the
    corporations[’] accountants to prepare a selling price” because, if he had done so, he would have
    known about “intangible values and goodwill.” Nelson acknowledged that none of the
    agreements used the words goodwill or intangibles, but asserted that he and Curia discussed
    goodwill every time they wrote a new agreement.

    No. 1-17-1653
    ¶ 57   On November 17, 2006, the district court granted Curia’s motion for partial summary
    judgment in part and denied it in part. The district court found that Curia properly exercised his
    option to purchase all of Nelson’s Plaza shares through his Option Exercises on March 2 and 3,
    2005. The court found that the purchase price would be calculated, using the formula in the 2000
    Agreement, and would be based on the February 2005 GM financial statement.
    ¶ 58   On November 27, 2006, Korey emailed Shifflett, advising him that “[a]pparently
    sometime back in November of 2004, [Nelson], [Curia] and [Debes] had a meeting where
    [Curia] agreed to pay 4.2 million [for] the stock.” Debes then sent Curia a letter confirming the
    amount and the financing. Korey emailed Shifflett again on December 3, 2006, with suggestions
    for Quarles & Brady’s motion for reconsideration. Korey suggested adding a sentence in the
    motion that stated: “For example, in November or December[ ] 2004, Curia and Nelson agreed
    on a price of 4.2 million for the stock in the presence of Ghram Debes, as evidenced by [the]
    attached letter.” Korey suggested that Quarles & Brady then include the Fifth Third letter from
    November 2004, committing to the $4.2 million loan as an exhibit.
    ¶ 59   On June 27, 2007, the district court entered an order granting Curia’s motion for
    summary judgment with regard to specific performance for the sale of Nelson’s Plaza shares.
    The court also found that the 2000 Agreement clearly and unambiguously did not include any
    adjustment for goodwill or other intangible assets in determining the purchase price. The court
    therefore set the purchase price at $2,188,720 for Nelson’s shares in Plaza. The court also left a
    number of issues pending, including whether Curia was entitled to use the name “Ken Nelson”
    for Plaza after he purchased the shares, and whether Curia was required to provide vehicles for
    Nelson and his wife.

    ¶ 60                              7. Appeal and Motion for Stay
    ¶ 61   Quarles & Brady appealed the district court’s judgment granting Curia’s motion for
    specific performance with regard to the Plaza shares to the Seventh Circuit while the unresolved
    issues the district court identified in its order remained pending in the district court. On
    September 5, 2007, Quarles & Brady filed a motion to stay the district court’s order. In that
    motion, Quarles and Brady alleged for the first time that in “September 2004, Curia and Nelson
    reached a verbal commitment whereby Curia would pay $4,200,000.00 for Nelson’s shares in
    both companies and would provide Nelson with certain perks including two automobiles of his
    choice for a period of 15 years.” The motion also alleged that Curia and Nelson continued to
    negotiate a fair market price for Curia to purchase all of Nelson’s shares in the two corporations,
    but sometime in late 2004 or early 2005, Curia decided that he could pay less than fair market
    value for Nelson’s shares if he tried to enforce the 1989 SPA and 1993 Modification. This
    information mirrored the statements in Nelson’s affidavit that accompanied the motion to stay.
    The district court denied the motion to stay.
    ¶ 62   On February 15, 2008, while the appeal was still pending in the Seventh Circuit, Quarles
    & Brady filed a second amended complaint for declaratory relief in the district court. In its claim
    for breach of fiduciary duty in the amended complaint, Quarles & Brady alleged that in 2004
    Curia agreed to purchase Nelson’s shares of Plaza and Mall for $4.2 million. Quarles & Brady
    alleged that Nelson, in reliance on this agreement, worked to obtain the automobile
    manufacturers’ approval for the sale, and Curia indicated to several third parties that he and
    Nelson had reached an agreement, but he subsequently reneged.

    ¶ 63                           8. Nelson Discharges Quarles & Brady
    ¶ 64   In April 2008, Nelson discharged Quarles & Brady. That same month, pursuant to the
    district court’s order, Nelson sold his shares in Plaza to Curia for $2.188 million. Nelson retained
    attorney Stewart Weltman, who handled the appeal, the remaining issues in the district court, and
    the ultimate settlement with Curia.
    ¶ 65                           9. Seventh Circuit Ruling and Settlement
    ¶ 66   On November 20, 2009, the Seventh Circuit reversed the district court’s ruling granting
    Curia’s motion for summary judgment and remanded the case for further proceedings. Curia v.
    Nelson, 
    587 F.3d 824
    , 832 (7th Cir. 2009). In so ruling, the Seventh Circuit found that, despite
    neither party raising the issue, the parties’ written agreements were ambiguous. 
    Id. at 829.
    Specifically, the court found that Paragraph 5 of the 1993 modification did not explicitly cancel
    the options, but it also was not inconsistent with the continued existence of the options. 
    Id. at 830.
    Accordingly the court found that summary judgment was inappropriate under the
    circumstances. 
    Id. at 832.
    ¶ 67   Rather than continuing the litigation in the district court after remand, in August 2010,
    Curia and Nelson reached a settlement agreement whereby Nelson transferred all of his shares in
    Mall to Curia in exchange for releasing Nelson of personal liability for Mall’s debt to Fifth
    Third. As part of the settlement agreement, Curia also paid Nelson $855,888 for Nelson’s 50%
    ownership stake in CRANK.
    ¶ 68                   B. Nelson’s Malpractice Action Against Quarles & Brady
    ¶ 69   Following the settlement with Curia, Nelson filed a complaint for legal malpractice
    against Quarles & Brady, alleging that it was negligent in its representation of him in the
    Underlying Litigation. The complaint was subsequently amended, and eventually dismissed by
    - 21 ­
    No. 1-17-1653
    the circuit court pursuant to section 2-615 of the Code of Civil Procedure (Code) (735 ILCS 5/2­
    615 (West 2010)). Nelson appealed, and this court reversed and remanded, finding that, based on
    Nelson’s allegations, it could not be said that Nelson could prove no set of facts from which a
    jury could find Quarles & Brady’s alleged negligence was the proximate cause of Nelson’s
    damages. Nelson v. Quarles & Brady, LLP, 
    2013 IL App (1st) 123122
    , ¶ 75.
    ¶ 70   On remand, Nelson filed the complaint at bar, alleging that Quarles & Brady was
    negligent in its representation throughout the Underlying Litigation. Specifically, Nelson alleged
    that Quarles & Brady was negligent in (1) failing to argue that Curia’s Option Exercises were
    ineffective because they were not the mirror image of the 1989 SPA options, (2) failing to argue
    that the 1989 SPA and subsequent agreements were ambiguous, and (3) failing to investigate and
    enforce the $4.2 million oral agreement that Nelson and Curia reached in 2004. At trial, 15
    witnesses testified over the course of 15 days, including Shifflett, Gatziolis, Nelson, Curia, and
    two expert witnesses.
    ¶ 71                              1. Curia’s Option Exercises
    ¶ 72   Shifflett testified that his primary goal in filing the complaint was to defeat Curia’s
    Option Exercises. He acknowledged Curia’s Option Exercises attempted to purchase a different
    number of shares than the amount of shares listed in the 1989 SPA options, but testified that he
    did not raise an argument that the Option Exercises were defective because they were not the
    mirror image of the 1989 SPA options because he did not think it would be persuasive. He
    testified that Quarles & Brady considered raising that argument, and the argument appeared in a
    draft of the reply brief in the Underlying Litigation, but Quarles & Brady ultimately chose to not
    raise that argument because the changes in the number of shares were agreed to by the parties in
    subsequent documents and because the second option in 1989 SPA provided Curia the option to
    - 22 ­
    No. 1-17-1653
    purchase 49% of the outstanding shares and third option provided Curia the option to purchase
    Nelson’s “remaining” shares, which is what Curia sought in his Option Exercises. He noted that
    because the 1989 SPA options provided a percentage, he believed that relevant case law would
    have supported the idea that as long as Curia purchased 49% of the shares with the second option
    and the remaining shares with the third option, as specified in the 1989 SPA, the district court
    could make an equitable adjustment to the actual number of shares to allow the purchase to go
    forward.
    ¶ 73   Edward Joyce, Nelson’s expert witness, testified that Quarles & Brady should have
    argued that Curia’s Option Exercises were defective because they were not a mirror image of the
    1989 SPA options. Joyce testified that as a result of the corporations’ recapitalization following
    the 1989 SPA, it would have been impossible for Curia to exercise the options pursuant to the
    terms of the 1989 SP, and thus his Option Exercises were ineffective. Joyce also testified that the
    case Shifflett relied on in contending that the court could make equitable adjustments to the
    number of shares was not relevant because the agreement in that case had a provision allowing
    the number of shares to be adjusted in the event of recapitalization, but there was no such
    provision in Nelson and Curia’s agreements. Joyce opined that had Quarles & Brady raised this
    argument, it was more likely true than not that they would have defeated Curia’s summary
    judgment motion. Joyce noted that there would be no disadvantage to raising this argument as an
    alternative method of relief and that Quarles & Brady’s failure to raise this argument showed a
    failure to exercise the knowledge, skill, and care ordinarily used by a reasonably careful attorney
    under the circumstances.
    ¶ 74   On cross-examination, Joyce acknowledged that Quarles & Brady made a version of the
    mirror image argument by including a contention that Curia’s Option Exercises erroneously used
    - 23 ­
    No. 1-17-1653
    the price formula from the 1993 Modification. However, Joyce testified that these were the
    wrong facts to support this claim and that Quarles & Brady should have instead argued that Curia
    attempted to purchase the wrong number of shares or that the options required Curia to offer to
    purchase Plaza’s real estate. Joyce also acknowledged that Nelson could have raised these
    arguments on remand from the Seventh Circuit.
    ¶ 75   Gino DiVito, Quarles & Brady’s expert, testified that it was unnecessary for Quarles &
    Brady to argue that the number of shares had changed from the 1989 SPA, because, as Shifflett
    testified, the second option specified a percentage of shares, 49%, for Curia to purchase and then
    the third option specified that Curia could purchase the “remaining” shares. DiVito noted that
    Curia’s Option Exercises mirrored these terms. DiVito also acknowledged that this argument
    was included in a draft brief by Quarles & Brady, but ultimately was not raised.
    ¶ 76                                       2. Ambiguity
    ¶ 77   With regard to ambiguity, Shifflett testified that he argued the written agreements were
    unambiguous in the motion for summary judgment because he did not believe there were any
    issues of fact to resolve. He also testified that Nelson did not provide any extrinsic evidence that
    would offer a different interpretation of the 1993 Modification. Gatziolis testified that part of
    their strategy at trial was to avoid discovery and get a ruling on their summary judgment motion.
    Shifflett testified that if there were an ambiguity in the written agreements, the district court
    could identify it, sua sponte, and deny the motion for summary judgment, and Quarles & Brady
    would be able to better focus its discovery.
    ¶ 78   Joyce testified that Quarles & Brady should have argued that the written agreements were
    ambiguous. Joyce noted that Paragraph 5 of the 1993 Modification, the “subsequently”
    paragraph, did not specify how many shares Curia would purchase or how Curia would pay for
    - 24 ­
    No. 1-17-1653
    them. Joyce further testified that it was ambiguous whether this paragraph was consistent with
    the 1989 SPA. Joyce testified that reading all of the agreements together, there was no clear
    indication of how Curia could exercise his options or whether he had a right to purchase
    Nelson’s shares. Joyce further testified that if the district court found the agreements were
    ambiguous, it would not have granted Curia’s motion for summary judgment, and there would
    have been an evidentiary hearing where Quarles & Brady could have introduced extrinsic
    evidence to demonstrate what Curia and Nelson thought when they entered into the agreement.
    Joyce testified that, within a reasonable degree of certainty, he believed that this argument would
    have prevailed had Quarles & Brady raised it before the district court. On cross-examination,
    Joyce acknowledged that although the Seventh Circuit found the agreements ambiguous, it also
    found that the interpretation of the written agreements urged by Quarles & Brady before the
    district court was a reasonable one.
    ¶ 79   DiVito testified that it was reasonable under the circumstances for Quarles & Brady to
    argue that the written agreements were not ambiguous. He testified that it was reasonable for
    Quarles & Brady’s to argue that Paragraph 5 of the 1993 Modification negated any unilateral
    right by Curia to exercise the options. He opined that there was no downside to arguing that the
    agreements were not ambiguous because the district court could find, sua sponte, that the
    agreements were ambiguous, regardless of what the parties claimed. He also noted that arguing
    ambiguity could have opened the door for Curia to raise arguments about what the parties
    intended when they entered into the agreements.
    ¶ 80                             3. $4.2 Million Oral Agreement
    ¶ 81   Nelson testified that in 2004, he decided he wanted to leave the automobile dealership
    business and retire. He approached Curia about buying out his share of stock in Plaza and Mall,
    - 25 ­
    No. 1-17-1653
    and Curia agreed. They based the price on the formula in the 1989 SPA and the June 2004 GM
    financial statement and came up with a price a little more than $4.1 million, so they rounded it up
    to $4.2 million for Nelson’s shares in both Plaza and Mall. Nelson testified that he said “I’ll sell
    you my shares for [$]4,200,000,” and Curia was “very excited” and said “yes.”
    ¶ 82   Nelson testified that they did not discuss when the deal would close at that time, but they
    knew they needed the automobile manufacturers’ approval for the transaction to approve Curia
    as the dealer. Nelson testified that he would have handled that process and that he could not
    direct the manufacturers to process an approval within a certain period of time. Nelson testified
    that neither he nor Curia said that the deal would not take place if they could not close the
    transaction by December 31, 2004.
    ¶ 83   Nelson further testified that in August or September, he and Curia met with Debes to ask
    Fifth Third to fund the $4.2 million to buy the stock. After that meeting, Nelson and Curia
    discussed the perks that Nelson was seeking, such as the health insurance and vehicles, and Curia
    indicated that he would be willing to provide those perks in exchange for the continued use of
    Nelson’s name for the dealerships. Nelson testified that he prepared the Stockholders’ Minutes
    and the Directors’ Resolutions. He believed that the nine conditions in the Stockholders’ Minutes
    were a separate agreement from the $4.2 million stock purchase agreement. He also testified that
    the “agreement” referred to in the Directors’ Resolutions was the $4.2 million oral agreement.
    Nelson testified that Curia signed the Directors’ Resolutions, but did not sign the Stockholders’
    Minutes because he said it was “too much.” Nelson nonetheless moved forward with contacting
    the manufacturers to obtain approval for the transaction.
    ¶ 84   Curia testified that, in 2004, he told Nelson that he wanted to “abide” by their written
    agreements and buy out his shares. Nelson, however, wanted more than what was provided for in

    the agreements; he wanted a retirement package. Curia testified that he never accepted any of
    Nelson’s offers to sell his shares, and he never agreed to two separate agreements—one for the
    sale of Nelson’s shares and one for the retirement package for Nelson. Curia testified that when
    he signed the Directors’ Resolutions, he believed he had an agreement to buy Nelson’s shares for
    a “sum certain” as calculated in accordance with the 1989 SPA. Curia further testified that when
    he went to Fifth Third in 2004 and secured funding for the purchase of Nelson’s shares, it was
    merely a preapproval and was not tied to any purchase price because the actual price of the
    shares could change each month, depending on the performance of the dealership, and the GM
    financial statements. Curia knew that as part of the approval process, he would have to provide
    manufacturers with proof that he could secure the funds to proceed with the buyout. Curia
    testified that his intention was to borrow enough money to purchase Nelson’s shares and to use
    the remainder as working capital and “combine loans.”
    ¶ 85    Nelson testified that, in late November or early December 2004, Curia told him that he
    was paying too much for Nelson’s shares. On December 3, 2004, he sent a letter to Curia,
    attempting to renegotiate the sale. He testified that he did not mention their $4.2 million oral
    agreement in this letter because Curia had already rejected that offer, so he was attempting to
    make another offer to sell his shares for $3.4 million, but Curia did not accept. In January 2005,
    he and Curia discussed approaching a broker to find a third party to purchase the dealerships and
    the real estate.
    ¶ 86    After receiving Curia’s Option Exercises in March 2005, Nelson sent a letter to Johnson
    at Quarles & Brady. Nelson testified that the Johnson Letter did not mention the $4.2 million oral
    agreement because at the time he was only concerned with Curia’s Option Exercises. With the
    assistance of Gatziolis, Nelson sent a letter to Curia on March 14, 2005, with an offer to sell his
    - 27 ­
    No. 1-17-1653
    shares for $3.4 million based on the September 2004 GM financial statement. Nelson understood
    that if Curia accepted the offer in this letter, he would not receive any retirement package or
    perks. Nelson acknowledged that he sent an email to Gatziolis on March 29, 2005, in which he
    did not mention the $4.2 million oral agreement.
    ¶ 87   On April 20, 2005, Nelson, Carol, and Korey met with Gatziolis at the Quarles & Brady
    office in Chicago. Nelson testified that, at that meeting, he told Gatziolis about the $4.2 million
    oral agreement and that Fifth Third had agreed to fund the transaction. Nelson testified that
    Gatziolis told him that oral agreements were not recognized in Illinois and did not ask him if he
    could provide any more information about the oral agreement. Carol testified that during the
    meeting, she was taking notes, but was not paying close attention. Referring to her notes, Carol
    testified that Gatziolis told them to “get over it,” and she believed that when he said that, he was
    referring to the $4.2 million oral agreement based on a “4.2” she had also written on the page.
    She acknowledged on cross-examination, however, that, based on her notes, she could not be
    sure whether that was said by Gatziolis or Nelson or whether the notes were her own thoughts.
    ¶ 88   Korey, who was the secretary of Mall and Plaza, and also a director, testified that the
    purpose of the April 20, 2005, meeting with Gatziolis was to try to reach a resolution with Curia
    after he had sent notice of his intent to exercise his options to purchase Nelson’s shares. Korey
    testified that Nelson told Gatziolis that he and Curia had reached an oral agreement to sell his
    shares in both Plaza and Mall for $4.2 million. Gatziolis asked Nelson if he had written the
    agreement down, but Nelson told him that they had not. Gatziolis told Nelson that “oral
    agreements are not enforceable in the state of Illinois. You can ask Korey about it. He knows. He
    studied the statute of frauds in law school.” Throughout the meeting, Gatziolis repeatedly told
    Neslon to get a deal done with Curia so that he could move on and retire.
    - 28 ­
    No. 1-17-1653
    ¶ 89   Gatziolis testified that when he first became involved in Nelson’s case, Nelson wanted to
    know if he was required to honor Curia’s Option Exercises. He learned that Nelson wanted to
    sell all of his shares and retire, but wanted a different price than what Curia had offered. He
    helped Nelson write a letter to Curia on March 13, 2005, and did not recall Nelson telling him
    about any oral agreement for $4.2 million. Before meeting with Nelson, Gatziolis reviewed the
    Directors’ Resolutions, the 1989 SPA, and subsequent written agreements; the November 2004
    Fifth Third loan commitment letter for $4.2 million; and the other materials in the Johnson
    Packet, including the Chronology with Curia’s responses. Gatziolis testified that none of these
    documents raised a question in his mind that Curia and Nelson had entered into an oral
    agreement in 2004. Specifically, Gatziolis testified that the comments made by Curia and Nelson
    in the Johnson Packet showed that they were not in agreement about the retirement package.
    Gatziolis further noted that there was no mention of sale price of $4.2 million in any of the
    documents he reviewed.
    ¶ 90   Gatziolis further testified that Nelson did not tell him about a $4.2 million oral agreement
    at the April 2005 meeting or in any of their communication before the meeting. He testified that
    he did not tell the Nelsons at the April 2005 meeting that oral contracts were not enforceable in
    Illinois. He further testified that, in April 2005, he understood that an oral agreement for the sale
    of stock could be enforced in Illinois with adequate evidence. He acknowledged, however, at his
    deposition that he testified that he did not recall whether the Nelsons told him there was an oral
    agreement for $4.2 million or whether he told them it was not enforceable and to get the deal
    behind them.
    ¶ 91   On April 27, 2005, Nelson sent an email to Gatziolis, in which he stated that he and Curia
    began “this process” in September 2004. Nelson said that he and Curia met with Debes at Fifth
    - 29 ­
    No. 1-17-1653
    Third to discuss their needs and “came up with 4.2M of funds” and Debes approved that amount.
    Nelson stated that “[s]ince that was the figure we agreed that we needed, perhaps that would be
    the selling price including all the perks, etc[.], that [Curia] would be more comfortable with.”
    Gatziolis forwarded the email to Shifflett and Cahill, and stated, “[f]ood for thought, although
    more like a fast.”
    ¶ 92   On April 29, 2005, hours before Quarles & Brady filed the initial complaint in the district
    court, Nelson sent another email to Gatziolis in which he stated, among other things, that Fifth
    Third agreed to loan Curia “up to” $4.2 million to purchase his shares in both corporations.
    Nelson further stated that “[Curia] and I agreed along with the Bank that the [$4.2 million]
    would be about what the selling price would be.” Nelson then identified the issues that he
    believed needed to be addressed going forward including the stock sale “which includes some
    type of Retirement Package.”
    ¶ 93   Gatziolis testified that neither of these emails raised the question of an agreement in his
    mind because the words “perhaps” and “about” and the phrase “up to” suggested that Nelson and
    Curia had agreed approximately what the selling price would be, but did not indicate an
    agreement because these were not definite terms. Gatziolis testified that Nelson did not tell him
    at any point before Quarles & Brady filed the complaint in the district court that he and Curia
    had agreed on a selling price of $4.2 million. Gatziolis further testified that he knew from his
    prior experience that in order for a change of ownership for an automobile dealership to be
    approved, the owners would have to submit information to the automobile manufacturers.
    Gatziolis acknowledged, however, that he did not contact the automobile manufacturers to
    determine if they had documentation that would support a claim for an agreement between
    Nelson and Curia for $4.2 million.
    - 30 ­
    No. 1-17-1653
    ¶ 94   Gatziolis testified that throughout the representation, his understanding was that Nelson
    would not settle unless he obtained the selling price he was looking for the shares and a
    retirement package. Gatziolis encouraged Nelson to settle while the litigation was pending and
    testified that he allowed Nelson to determine his own offers for a selling price during the
    negotiations.
    ¶ 95   Gatziolis and Shifflett testified that the initial complaint was filed on April 29, 2005.
    Both testified that the purpose for filing the complaint was to have something pending in the
    court before the closing date on Curia’s Option Exercises on May 2. Shifflett and Gatziolis
    testified that Shifflett handled the litigation while Gatziolis mostly handled the settlement
    negotiations. Shifflett testified that when he filed the complaint, he had the information in the
    Johnson Packet, the Directors’ Resolutions, and the emails Nelson sent to Gatziolis on April 27
    and April 29. Shifflett was unsure whether he had the letter from Fifth Third from November
    2004, committing to the loan of $4.2 million, but in any event he testified that he did not ask
    Nelson about the letter before filing suit. Shifflett testified that none of the information he
    received before filing the complaint put him on notice to investigate a potential oral agreement
    between Curia and Nelson.
    ¶ 96   Shifflett testified that he did not believe he had a duty to investigate a potential oral
    agreement because Nelson’s letters to Curia indicated that they were not in agreement. Shifflett
    also observed that Curia had not signed the Stockholders’ Minutes, and at no point did Nelson
    say that he and Curia had an agreement to sell his shares for $4.2 million. Shifflett also knew that
    Nelson and Curia would be required to submit information to the automobile manufacturers in
    order to approve the sale, but he did not know what information they had submitted. When he
    - 31 ­
    No. 1-17-1653
    started working on the complaint, he asked Nelson to give him everything he had, but did not
    contact the manufacturers.
    ¶ 97   Shifflett testified that his primary goal in filing the complaint was not to force Curia to
    purchase Nelson’s stock for $4.2 million, but was to defeat Curia’s Option Exercises. Shifflett
    testified that he believed that if Curia’s options were “knock[ed] out,” Nelson would be able to
    negotiate the sale of his shares to Curia, but as long as the options existed, Curia would not
    negotiate. Shifflett believed Nelson’s goal was to establish a purchase price for all the stock, with
    the addition of some added benefits, and not just for the stock alone.
    ¶ 98   Shifflett acknowledged that the complaint did not include a contention that Curia and
    Nelson had reached an agreement for Curia to buy Nelson’s shares for $4.2 million. Shifflett
    testified that he believed there was insufficient evidence to support such a claim. Shifflett knew
    that Curia and Nelson had negotiated in the summer of 2004, but did not believe they had
    reached an agreement at any point. Like Gatziolis, Shifflett testified that the emails Nelson sent
    on April 27 and April 29 did not raise the possibility of an agreement because Nelson used words
    like “perhaps,” “about,” and “up to.” Shifflett testified that he discussed the filings with Nelson
    and that Nelson never mentioned an oral agreement to sell his shares to Curia for $4.2 million.
    ¶ 99   Nelson conceded that he did not say anything about the oral $4.2 million agreement in the
    Johnson Letter or the Johnson packet. He acknowledged that there was nothing about the
    agreement in the March 2005 letter to Curia that Gatziolis helped him write or in the July 2005
    Ken’s Story. Nelson further acknowledged that neither he nor Korey included any information
    about a July 2004 agreement or an oral agreement for $4.2 million when they edited the filings
    and returned them to Quarles & Brady.
    - 32 ­
    No. 1-17-1653
    ¶ 100 After the district court granted Curia’s motion for summary judgment, Nelson testified
    that he contacted Thomas at Toyota to ask for the purchase price that Curia included with his
    application. Thomas replied that the original agreement was for both Plaza and Mall and that
    Toyota’s “understanding” was for a purchase price of $4.2 million. Nelson testified that he
    shared this information with Gatziolis and Shifflett in March 2006, but neither of them recalled
    receiving this information at that time.
    ¶ 101 Shifflett testified that the first time he received any communication about a potential oral
    agreement for $4.2 million was Nelson’s email from August 29, 2006, after the district court had
    ruled on the summary judgment motions. Shifflett, however, did not believe that this email was
    definitive because Nelson said in the email that he sent the information about the agreement to
    the manufacturers, but Shifflett noted that Nelson’s letters to the manufacturers did not include
    any information about a $4.2 million agreement. Shifflett had no reason to believe Nelson had
    sent any additional documentation to the manufacturers because Shifflett had previously asked
    Nelson to send him “everything.” In addition, Shifflett testified that he believed Nelson still
    wanted all of his retirement perks and that he and Curia were still negotiating those items and
    had not actually reached an agreement. Shifflett testified that the information in this email did
    not create a sufficient basis to file an amended complaint alleging the existence of an oral
    agreement for $4.2 million.
    ¶ 102 Shifflett also acknowledged that he received emails from Korey in November and
    December of 2006, in which Korey stated that Curia agreed to purchase Nelson’s shares for $4.2
    million and that they discussed this agreement in the presence of Debes. Shifflett testified that he
    did not contact Debes for more information, because he believed Debes was biased toward Curia.
    - 33 ­
    No. 1-17-1653
    ¶ 103 Debes testified that Nelson and Curia approached him in September 2004 about a request
    for a loan for Curia to purchase all of Nelson’s shares in the two dealerships. Debes testified,
    however, that Nelson and Curia never told him that they had reached an oral agreement for the
    sale of the shares, but could not say whether Curia and Nelson had conversations between each
    other in which they reached an agreement. He testified that when generating the loan documents,
    he understood that Curia and Nelson were still negotiating toward a deal because they had
    differing views about what Curia would pay for the shares and what Nelson would accept for
    them. Debes testified that Fifth Third would not have disbursed the funds based on an oral
    agreement and would have also needed the manufacturers’ approval before it would disburse the
    funds.
    ¶ 104 With regard to the November 2004 letter committing Fifth Third to the $4.2 million loan,
    Debes testified that the commitment letter provided that the funds would be issued for the
    purchase of Nelson’s shares in Plaza and Mall, and that it would be inconsistent with Fifth
    Third’s approval for Curia to use the funds for another purpose. He testified, however, that it was
    common in a situation like this one to get preapproval even before the final terms of the
    agreement were established. Debes acknowledged that he sent these loan documents to Toyota
    and Nissan at Curia’s request. Debes also acknowledged that he cooperated with Curia’s attorney
    during the Underlying Litigation because Fifth Third wanted Curia to become the owner of the
    dealerships.
    ¶ 105 Shifflett testified that, in early 2008, Nelson told him that he received information from
    Thomas at Toyota about a $4.2 million price, and Shifflett told him to get more information.
    Shifflett testified that he did not contact Thomas because he believed she would direct him to
    Toyota’s legal department because he was a lawyer. On February 15, 2008, Quarles & Brady
    - 34 ­
    No. 1-17-1653
    filed an amended complaint in the district court, alleging that in 2004 Curia agreed to purchase
    Nelson’s shares for $4.2 million. Shifflett said this allegation was based on the information from
    Nelson that Thomas had documentation reflecting a purchase price of $4.2 million. On March
    20, 2008, Nelson emailed Shifflett to inform him that he asked Thomas when she received
    information from Curia that he was paying $4.2 million for the two dealerships. Nelson learned
    that Curia did not send a document to Toyota containing that information, but Thomas told him
    there was notation in her notes that the figure came from a communication with Curia that
    occurred in November 2004, before Thomas started in the position and Zangri was the Market
    Representation Administrator for Toyota.
    ¶ 106 Thomas testified that she had no personal knowledge of what happened between Zangri
    and Nelson or Curia. She testified that she likely would have had some documentation to support
    the $4.2 million figure in her email to Nelson, but she did not know where that amount came
    from. She testified that Toyota would have to know the purchase price of the shares in order to
    finalize the approval process. Zangri testified that in connection with the change of ownership
    for Plaza and Mall, Toyota received the Directors’ Resolutions. Based on these documents,
    Zangri made an “assumption” that Curia had negotiated a deal to buy out Nelson’s remaining
    shares. Zangri testified that he started the review process based on the information provided by
    Nelson and Curia and that he would not start that process unless there was an agreement that had
    been reached. He further testified, however, that in all the information Toyota received from
    Nelson or Curia, there were no terms of a deal or a price term. Zangri also testified that Toyota
    would not have approved the transaction based on the November 2004 loan commitment letter
    from Fifth Third because the loan agreement allowed shares of the dealership to be pledged to a
    - 35 ­
    No. 1-17-1653
    third party and allowed for the debt to be cross-collateralized, which ran afoul of Toyota
    standards.
    ¶ 107 Fariborz Nour testified at his deposition that he was the market representation specialist
    for Nissan in 2004 and 2005, and similarly testified that Nissan did not have documentation
    showing the purchase price or terms of an agreement between Nelson and Curia. He testified,
    however, that based on his experience, a request for the approval of a change of majority
    ownership interest would “not really get off the ground” without an asset or stock purchase
    agreement, but could not say whether such an agreement was provided in this case. Nour
    testified that he could not say whether Nissan required owners to provide a purchase price for the
    shares, but testified that it was not one of his requirements.
    ¶ 108                               a. Expert Witness Testimony
    ¶ 109 Joyce testified that based on the information Quarles & Brady had prior to filing the
    complaint, they should have been aware of a potential agreement between Curia and Nelson for
    the sale of Nelson’s shares. Specially, Joyce testified that based on the Fifth Third letter from
    November 2004, it should have been “obvious” to Quarles & Brady to contact the bank and
    determine the purpose of the loan commitment. Joyce also observed that the Directors’
    Resolutions provided that Nelson would contact the manufacturers in connection with an
    agreement, which should have prompted Quarles & Brady to contact the manufacturers to
    determine what documentation they had related to the sale of the corporations’ shares to Curia.
    Joyce testified that, in his opinion, a reasonably careful attorney under the circumstances would
    have conducted this investigation before filing the complaint. Joyce acknowledged, however,
    that the Directors’ Resolutions did not refer to a $4.2 million agreement.
    - 36 ­
    No. 1-17-1653
    ¶ 110 Joyce further testified that if Quarles & Brady had contacted Nissan and Toyota, they
    would have obtained documents that Curia had submitted to those manufacturers, which could
    have contained terms of the agreement and showed that Curia had been contacting the
    manufacturers in connection with a potential agreement. Joyce noted that Thomas told Nelson
    that her notes reflected that Curia told Toyota that he had agreed to purchase Nelson’s shares for
    $4.2 million. He acknowledged, however, that Thomas could not provide any documentation
    supporting this statement, and that Thomas was not employed at that position at Toyota when the
    approval process started, so she had no personal knowledge of Curia’s representations. Joyce
    also noted that there were documents that Nissan had sent to Nelson and Curia that stated that
    Nissan had approved the stock purchase agreement between Nelson and Curia. He further opined
    that Quarles & Brady would have learned from the manufacturers that they will not start
    processing an approval for a sale of a majority ownership interest until they are satisfied there
    has been an agreement between the parties.
    ¶ 111 Joyce further testified that if Quarles & Brady had undertaken this investigation, they
    would have learned that Nelson’s goal in retaining them was to sell all of his shares of stock in
    the two dealerships for $4.2 million. Based on their investigation, Quarles & Brady should have
    informed Nelson that he had an enforceable oral contract between him and Curia for the sale of
    his shares in the two dealerships for $4.2 million. Joyce testified that Nelson would have had a
    very strong claim for breach of oral contract against Curia based on the evidence from Fifth
    Third that it had committed to the $4.2 million loan and the information from the manufacturers
    that they had been asked to approve a sale of Nelson’s majority interest to Curia.
    ¶ 112 With regard to the retirement benefits, Joyce testified that Nelson believed that he had a
    deal for these benefits, but Curia did not. Joyce opined that whether those benefits were part of
    - 37 ­
    No. 1-17-1653
    the stock sale agreement would be reserved for the trier of fact. Nonetheless, Joyce testified that
    these benefits had no relevance to the stock sale for $4.2 million because Curia and Nelson
    viewed them as separate transaction. Joyce noted that both parties continued to process the sale
    by contacting the manufacturers and Fifth Third even after Curia did not sign the Stockholders’
    Minutes, which outlined the retirement benefits. Joyce did not believe the perks were a condition
    of the stock sale agreement.
    ¶ 113 Joyce also testified that Gatziolis, in telling Nelson that oral contracts are not enforceable
    in Illinois, did not perform as a reasonably careful lawyer under the circumstances. Joyce noted
    that the two emails Nelson sent to Gatziolis on April 27 and April 29, 2005, should have
    provoked Gatziolis to speak to Fifth Third to determine the purpose of the loan. After
    investigating Fifth Third and the manufacturers, Gatziolis should have interviewed Nelson and
    would have learned about Nelson’s goals and his attempts to continue the approval process with
    the manufacturers after Curia reneged. Joyce testified that Gatziolis should have directly asked
    Nelson for any documents related to the sale of stock to identify other potential sources of
    information that would help him determine Nelson’s rights and obligations.
    ¶ 114 Joyce testified that Quarles & Brady should have included an argument regarding the
    $4.2 million oral contract in the complaint because merely defeating the stock options, as
    Quarles & Brady sought to do with the complaint, would not have achieved Nelson’s goal;
    Nelson still would have retained his ownership interest in the dealerships if he had prevailed. An
    argument that he and Curia had entered into an oral agreement to sell Nelson’s shares for $4.2
    million, however, would have achieved Nelson’s goal if he had prevailed. Joyce opined that,
    based on the documentation and testimony available to Quarles & Brady, it was more likely true
    than not that Nelson would have prevailed on the argument that he had a valid and enforceable
    - 38 ­
    No. 1-17-1653
    oral contract with Curia for the sale of his shares for $4.2 million if Quarles & Brady had raised
    that argument before the district court. Joyce concluded that Quarles & Brady’s failure to assert
    this argument demonstrated Quarles & Brady’s failure to perform as a reasonably careful lawyer
    under the circumstances.
    ¶ 115 DiVito testified that, in his opinion, Quarles & Brady used the experience, skill, and
    knowledge that a reasonably careful lawyer would use under the circumstances. He testified that
    Quarles & Brady was entitled to rely on the information provided to them by Nelson in the
    Johnson Letter, and the other documents Nelson submitted to Quarles & Brady. DiVito opined
    that this documentary evidence, as well as the other information Nelson provided to Quarles &
    Brady, did not support a claim for an oral agreement. DiVito noted that in the documentation that
    he reviewed in preparation for his testimony, he did not see any contemporaneous evidence that
    referenced, documented, or confirmed the alleged oral agreement. DiVito testified that, instead,
    the documentation indicated that, from the beginning, Nelson was “bemoaning” that Curia would
    not negotiate with him and declined all of his offers. DiVito testified that if Nelson and Curia had
    reached an oral agreement, Nelson would be “screaming it from the rooftops” and not saying that
    Curia had not accepted his offers. DiVito testified that Quarles & Brady did not have a duty to
    interview Nelson about a potential oral agreement because they did not have any information
    regarding the possibility of the existence of such an agreement in 2005. DiVito testified that
    Gatziolis’ testimony and the documentary evidence indicated that Gatziolis may have known
    about the loan commitment from Fifth Third and the negotiations between Nelson and Curia, but
    he had no reason to know about any oral agreement.
    ¶ 116 DiVito further testified that Quarles & Brady had no duty to contact the automobile
    manufacturers because they already had all of the information from Nelson. Quarles & Brady
    - 39 ­
    No. 1-17-1653
    had no reason to suspect that there was an oral agreement because all of the information they had
    from Nelson indicated there was no agreement. DiVito testified that Quarles & Brady also had
    no duty to contact Fifth Third. DiVito concluded that, at the time the complaint was filed, there
    was no evidence to allege the existence of an oral agreement for $4.2 million and the arguments
    Quarles & Brady made in the complaint were reasonable in an attempt to defeat Curia’s Option
    Exercises. DiVito noted that the evidence showed that Quarles & Brady did not become aware of
    a potential oral agreement until the second half of 2006, after the district court had already ruled.
    ¶ 117                              4. The Circuit Court’s Ruling
    ¶ 118 The circuit court delivered its judgment in a written order. In its order, the circuit court
    recounted the testimony of Joyce and found that the evidence presented failed to show that
    Quarles & Brady was aware, before filing the lawsuit in the district court on April 29, 2005, that
    Nelson believed he had reached an oral agreement for the sale of his shares only for $4.2 million.
    The court continued that even after Quarles & Brady filed the lawsuit, Nelson’s continued
    communication with Quarles & Brady did not reveal such an agreement. Instead, the court found
    that the evidence suggested that Nelson desired to reach an agreement with Curia, made efforts
    in furtherance of a sale, and negotiated over terms, but ultimately did not reach an agreement
    with Curia. The court determined that it only became clear after the district court ruled that
    Nelson was claiming that he had reached an enforceable oral agreement with Curia. Ultimately,
    the court determined that “[w]hen segregating the evidence of what [Quarles & Brady] was told,
    or learned over time, from the evidence which would have been admissible at a trial for breach of
    contract, it becomes clear that plaintiff has failed to establish that it is more likely than not that
    Nelson would have won that breach of contract case.” The court therefore determined that
    Nelson had failed to establish the proximate cause element of his legal malpractice claim.
    - 40 ­
    No. 1-17-1653
    ¶ 119 The court further found that Nelson had failed to establish negligence with regard to his
    claims that Quarles & Brady should have argued that Curia’s Option Exercises were invalid
    because they were not the mirror image of the 1989 SPA options and that the written agreements
    were ambiguous. The court determined that Quarles & Brady’s positions could not judged by
    their outcome, but rather should be judged by whether Quarles & Brady deviated from the
    standard of care. The court further found that Nelson failed to establish proximate cause with
    regard to Quarles & Brady’s failure to raise those arguments because, after the Seventh Circuit
    reversed and remanded the case, Nelson elected to settle with Curia and thus forfeited his right to
    pursue further litigation on remand. Nelson now appeals.
    ¶ 120                                     II. ANALYSIS
    ¶ 121 On appeal, Nelson contends that the circuit court erred in rejecting his legal malpractice
    claim where the evidence overwhelming showed that Nelson and Curia entered into an oral
    agreement for Curia to purchase Nelson’s stock for $4.2 million and that Quarles & Brady was
    aware of the agreement by the time it filed the complaint in April 2005. Nelson contends that the
    court erred in rejecting his claim that Quarles & Brady was negligent for failing to assert this
    claim in the district court. Nelson further contends that the court erred in rejecting his claim that
    Quarles & Brady deviated from the standard of care by failing to argue that Curia’s Option
    Exercises were defective because they were not the mirror image of the options in the 1989 SPA.
    Nelson also asserts that the court erred in rejecting his claim that Quarles & Brady deviated from
    the standard of care by failing to argue that the written agreements were ambiguous. Finally,
    Nelson contends that the court erred in finding that Quarles & Brady’s negligence was not the
    proximate cause of his damages.

    ¶ 123 To prevail on a claim of legal malpractice, a plaintiff must show (1) an attorney-client
    relationship, (2) that the defendant attorney owed the plaintiff client a duty of care arising out of
    that attorney-client relationship, (3) that the defendant attorney breached that duty, and (4) that
    the plaintiff client suffered injury as a proximate result of the defendant attorney’s breach.
    Warnock v. Karm Winand & Patterson, 
    376 Ill. App. 3d 364
    , 368 (2007) (citing Northern Illinois
    Emergency Physicians v. Landau, Omahana & Kopka, Ltd., 
    216 Ill. 2d 294
    , 306 (2005)). In
    order to establish proximate cause in a legal malpractice action, the plaintiff client must
    essentially prove “a case within a case,” i.e., that “but for” the attorney’s negligence, the plaintiff
    would have prevailed in the underlying action. See First National Bank of LaGrange v. Lowrey,
    
    375 Ill. App. 3d 181
    , 196 (2007). The injury in a legal malpractice action is not a personal injury,
    or the attorney’s negligent act itself, but is a “pecuniary injury to an intangible property interest
    caused by the lawyer’s negligent act or omission.” Northern Illinois Emergency 
    Physicians, 216 Ill. 2d at 306
    .
    ¶ 124 As both parties recognize, generally, the standard of review in a bench trial for a legal
    malpractice action is whether the court’s judgment was against the manifest weight of the
    evidence. Eychaner v. Gross, 
    202 Ill. 2d 228
    , 251 (2002); Kalata v. Anheuser-Busch Cos., 
    144 Ill. 2d 425
    , 433 (1991). “A decision is against the manifest weight of the evidence only when an
    opposite conclusion is apparent or when the findings appear to be unreasonable, arbitrary, or not
    based on the evidence.” 
    Eychaner, 202 Ill. 2d at 252
    . On review, we will not substitute our
    judgment for that of the trier of fact. 
    Id. ¶ 125
    Despite acknowledging this general rule, Nelson nonetheless contends that this court
    should not accord the circuit court’s ruling any deference. Nelson asserts that, in its order, the
    - 42 ­
    No. 1-17-1653
    circuit court did not make any specific factual findings and that aspects of its decision were
    contrary to uncontested facts and documentary evidence. Nelson contends that, as such, we
    should not defer to the court’s judgment, which ignores the uncontradicted testimony at trial and
    the documentary evidence establishing the oral $4.2 million stock purchase agreement. Nelson
    further maintains that this court should review de novo the trial court’s ruling that Nelson failed
    to prove the proximate cause element of his claim because he settled the Underlying Litigation
    after the Seventh Circuit’s remand because this finding was “incorrect as a matter of law.”
    ¶ 126                  1. The Manifest Weight Standard Applies to this Action
    ¶ 127 Contrary to Nelson’s contentions, the deference afforded to the trial court under the
    manifest weight of the evidence standard is not applied only where the circuit court makes
    specific factual findings and credibility determinations on the record. Rather, we give deference
    to the circuit court because it is in the best position to observe the conduct and demeanor of the
    parties and the witnesses, and is intimately familiar with the evidence. Best v. Best, 
    223 Ill. 2d 342
    , 350 (2006); In re D.F., 
    201 Ill. 2d 476
    , 498-99 (2002). Here, it is apparent from the record
    that the court was required to make credibility determinations and factual findings in determining
    when Quarles & Brady knew about Nelson’s claim that he entered into an oral agreement with
    Curia for the sale of his shares, given the contradictory testimony that was presented on this issue
    by Nelson, Korey, Gatziolis, Shifflet, and others, as well as the documentary evidence presented.
    It would defy this court’s function to hold that we should not defer to the circuit court’s
    determination on these matters because they were not made on the record. Instead, on review, we
    should not substitute our judgment for that of the circuit court regarding the credibility of the
    witnesses, the weight to be given the evidence presented, or the inferences to be drawn from that
    evidence. In re 
    D.F., 201 Ill. 2d at 499
    . In addition, as discussed in detail below, we cannot say
    - 43 ­
    No. 1-17-1653
    that the evidence presented regarding the oral stock purchase agreement was “uncontradicted,”
    as Nelson suggests.
    ¶ 128 We are not persuaded by the precedent cited by Nelson, Chicago Investment Corp. v.
    Dolins, 
    107 Ill. 2d 120
    (1985), and Long v. Arthur Rubloff & Co., 
    27 Ill. App. 3d 1013
    (1975). In
    neither case did the court hold that a reviewing court should not defer to the findings of the
    circuit court where the circuit court failed to make specific factual findings and credibility
    determinations on the record. In Chicago Investment Corp., the supreme court did not find that
    trial court had an “obligation” to make factual findings on the record, but merely stated that
    where the trial court is the finder of fact, it has the obligation to make such findings. Chicago
    Investment 
    Corp., 107 Ill. 2d at 124
    . Similarly, in Long, this court specifically found that such
    factual findings are “not required” to be on the record, but merely stated that it would be “better
    practice” for the trial court to set forth the reasons for its judgment. 
    Long, 27 Ill. App. 3d at 1022
    n.4. We express no opinion regarding whether such a procedure would be “better practice,” but
    we observe that our precedent is clear that a trial court is not required to state the reasoning for
    its judgment on the record in order for the manifest weight of the evidence standard to apply and
    for this court to accord deference to its credibility and factual findings. Here, it is clear from the
    evidence presented that the circuit court was required to make certain credibility and factual
    determinations, and our well-established precedent directs us to accord deference to such
    determinations, whether or not the court explains the reasoning for its determinations or whether
    or not such determinations are made on the record. Accordingly, we will review the court’s
    ruling to determine whether its judgment was against the manifest weight of the evidence.

    ¶ 129                              B. $4.2 Million Oral Agreement
    ¶ 130 Nelson first contends that evidence presented at trial established that Nelson and Curia
    entered into an oral agreement for Curia to purchase Nelson’s stock for $4.2 million and that
    Quarles & Brady was aware of that agreement before it filed the complaint in April 2005. Nelson
    asserts that there is overwhelming evidence of the agreement from the testimony of both Curia
    and Nelson, their conduct after the oral agreement, the documentary evidence, and the testimony
    of third parties. Nelson contends that the circuit court’s determinations that Quarles & Brady did
    not know about the oral agreement before the district court ruled and that Nelson presented
    insufficient evidence to show that he would have prevailed on a breach of contract claim based
    on the $4.2 million oral agreement was against the manifest weight of the evidence.
    ¶ 131 1. The Circuit Court’s Ruling that Quarles & Brady Did Not Know About Nelson’s Claim
    for a $4.2 Million Oral Agreement Before the District Court Ruled 1 Was Not
    Against the Manifest Weight of the Evidence
    ¶ 132 Here, the evidence presented at trial shows that when Nelson approached Quarles &
    Brady in March 2005, he was seeking legal advice with regard to his rights after Curia’s Option
    Exercises. None of the documentation Nelson submitted to Quarles & Brady at that time
    included information that would indicate that he and Curia had entered into an oral agreement for
    the sale of his shares for $4.2 million. In fact, in the Johnson Letter, Nelson specifically stated
    that he approached Curia in September 2004 about purchasing his stock with “some conditions,”
    but he and Curia met in January 2005 and realized they “were not in agreement with either the
    1
    Nelson contends that in its written order, the circuit court focused on whether Quarles & Brady
    knew about the oral agreement before filing the complaint in April 2005, where the relevant inquiry
    should have been whether Quarles & Brady knew about Nelson’s claim before the district court ruled on
    the motions for summary judgment. However, the circuit court’s order reflects that it also considered that
    “[e]ven after the lawsuit was filed, ongoing discussions and receipt of emails and documents never
    revealed such a claim from Nelson.” The court also found that “at no time before the lawsuit was filed, or
    until after the district court ruled, did it become clear that Nelson was making the claim that an
    enforceable oral agreement existed since 2004.” (Emphasis added.)
    - 45 ­
    No. 1-17-1653
    purchase price or its application.” Although Nelson stated that funding was “available” for the
    stock sale through Fifth Third, Nelson did not state that he and Curia had reached an agreement
    and that Curia had reneged.
    ¶ 133 Similarly, none of the documents in the Johnson Packet would indicate to Quarles &
    Brady that Nelson and Curia had entered into an oral agreement for the sale of Nelson’s shares
    sometime in 2004. Like the Johnson Letter, the Chronology makes no reference to a $4.2 million
    oral agreement, and, in fact, Nelson stated that there was “no reason” for him to send letters to
    the manufacturers of his “wish” to sell until they had put together a retirement package. The
    Stockholders’ Minutes likewise lack any detail about an oral agreement for the sale of Nelson’s
    shares and, in any event, are not signed by Curia.
    ¶ 134 We observe that there was some discussion at trial, and in the briefs before this court,
    regarding whether Shifflett and Gatziolis had the Directors’ Resolutions before filing the
    complaint. Whether or not Quarles & Brady had these documents before the district court ruled,
    however, does not change our conclusion. The Directors’ Resolutions simply stated that the
    stockholders would accept an agreement whereby “[Nelson] would sell his 8000 shares in this
    corporation (52.7%) to [Curia], and that the manufacturers [would] be contacted to facilitate the
    transaction.” At trial Nelson testified that the “agreement” referred to in the Directors’
    Resolutions was the same agreement referenced in the Stockholders’ Minutes. The Stockholders’
    Minutes provided that it was “resolved that the following conditions of the sale and transfer of
    stock from [Nelson] to [Curia] be approved by the Board of Directors.” The Stockholders’
    Minutes then listed nine conditions, the first of which provided that the sale of the stock to Curia
    be in accord with the 1989 SPA. Gatziolis acknowledged that the Directors’ Resolutions may
    have put him on notice of an agreement between Curia and Nelson for the sale of shares, but
    - 46 ­
    No. 1-17-1653
    referred to the Stockholders’ Minutes, which were dated the day before and not signed by Curia.
    Thus, Gatziolis had no reason to believe that there had been an agreement between Nelson and
    Curia. Again, neither the Stockholders’ Minutes nor the Directors’ Resolutions contain any
    reference to an oral agreement for $4.2 million.
    ¶ 135 We also find the November 2004 commitment letter from Fifth Third was insufficient to
    put Quarles & Brady on notice of an oral agreement between Nelson and Curia. The letter does
    not refer to an agreement, but provides that Fifth Third was committed to lend Plaza $4.2 million
    to provide Curia with sufficient funds to buy out Nelson’s ownership interest in Plaza and Mall.
    In examining this document, Quarles & Brady could rely on the information provided by Nelson
    in the Johnson Letter that, although funding for a stock sale was “available” from Fifth Third,
    Nelson and Curia had not reached an agreement. This letter must also be viewed in context with
    the other information Nelson provided to Quarles & Brady. For example, on April 27 and 29,
    2005, Nelson emailed Gatziolis to provide some context for the Fifth Third commitment letter. In
    both emails, Nelson stated that Fifth Third agreed to loan $4.2 million and that would “perhaps”
    be the selling price, and it would be “about” what Curia needed to purchase his shares. Gatziolis
    testified that this uncertain language did not put him on notice of any agreement between the
    parties. Also, in both emails, Nelson indicated that the agreement for the sale of shares included
    a retirement package or “perks.” The previous documents Nelson had provided to Quarles &
    Brady, including the Chronology and the Stockholders’ Minutes, unequivocally showed that
    Curia had not agreed to provide a retirement package, and thus would indicate to Quarles &
    Brady that there had been no agreement between the parties.
    ¶ 136 Similarly, the record shows that while drafting the complaint, Quarles & Brady sent
    drafts to Nelson and Korey for their review. In revising the complaint, Nelson and Korey
    - 47 ­
    No. 1-17-1653
    specifically amended sections of the complaint to provide that Nelson had approached Curia
    about selling his shares, but that Curia did not accept any of Nelson’s offers. Again, in July 2005,
    Nelson sent Ken’s Story to Quarles & Brady in which he again stated that he had approached
    Curia with an offer to buy his shares, but Curia had not accepted his offers and had refused to
    even make a counteroffer. Nelson contends that he stated that Curia did not accept any of his
    offers because he was relying on Gatziolis’ legal advice that oral contracts were not enforceable
    in Illinois. However, it is a different matter for Nelson to state that Curia orally accepted his
    offer, but that it is not enforceable, than it is for Nelson to say that Curia did not accept his
    offers. Moreover, Nelson indicated in various documents, including the Chronology, that Curia
    did not accept his offers to sell his shares even before the April 20, 2005, meeting where Nelson
    claims Gatziolis told him that oral agreements were not enforceable in Illinois.
    ¶ 137 In short, every documented communication Nelson had with Quarles & Brady until after
    the district court’s ruling suggested that Nelson had approached Curia with offers to sell his
    shares, but Curia had not accepted. As DiVito testified, if Nelson and Curia had reached an oral
    agreement, Nelson would be “screaming it from the rooftops” and not saying that they had not
    reached an agreement. Despite Joyce’s testimony that the information Nelson provided to
    Quarles & Brady should have put them on notice of the oral agreement, given the abundant
    evidence presented suggesting that Curia and Nelson had not reached an agreement, we cannot
    say that the circuit court’s ruling was against the manifest weight of the evidence.
    ¶ 138 Nelson contends, however, that he, Carol, and Korey each testified that at the April 20,
    2005, meeting, Nelson told Gatziolis about the oral agreement and Gatziolis told him that it was
    not enforceable in Illinois. Nelson asserts that the court “completely ignored” this testimony in
    rejecting his claim. The court’s order suggests, however, that the court did not ignore this
    - 48 ­
    No. 1-17-1653
    testimony, but instead accepted Gatziolis’ testimony that Nelson did not tell him about the oral
    agreement at the meeting, and that Gatziolis did not tell Nelson that oral agreements are not
    enforceable in Illinois. Nelson asserts that this testimony contradicted Gatziolis’ testimony at his
    deposition where he stated that he could not recall whether Nelson told him about an oral
    agreement; however, this apparent contradiction created a credibility determination that was
    within the province of the circuit court to resolve. As discussed, we defer to the judgment of the
    circuit court on these issues because the circuit court is in the best position to observe the
    conduct and demeanor of the parties and the witnesses. 
    Best, 223 Ill. 2d at 350
    . The court’s order
    implicitly suggests that it accepted Gatziolis’ testimony on this issue and did not accept the
    testimony of Nelson, Carol, and Korey. We cannot say, based on the record before us, that such a
    determination was against the manifest weight of the evidence.
    ¶ 139 Nonetheless, Nelson asserts that Gatziolis’ testified at trial he was “generally” aware in
    April 2005 that Nelson and Curia had entered into an oral agreement for the sale of Nelson’s
    shares for $4.2 million and Curia had reneged. Nelson contends that the trial court’s ruling is
    therefore impossible to sustain in light of this admission. To support this contention, however,
    Nelson relies on testimony that was taken out of context and that Gatziolis later clarified. At trial,
    Nelson’s counsel asked Gatziolis about a letter Nelson had written to Debes that Gatziolis
    reviewed in April 2008.
    “Q. And what it says here is: You [(Debes)], [Curia] and I met at the corporation
    offices in Dixon, Illinois in September of 2004 at which time Mr. Curia and I asked Fifth
    Third Bank to loan Mr. Curia our agreed upon purchase price of *** 4,200,000 for my
    shares in the two corporations. On November 4th, 2004 we received your commitment
    letter stating that you would loan Rick Curia 4,200,000 to purchase my shares in Auto
    - 49 ­
    No. 1-17-1653
    Plaza and Auto Mall. The stock *** purchase was to close by year-end, but Mr. Curia
    reneged on our agreed price as stated in your letter.
    ***
    Q. This was the same thing Mr. Nelson told you from the time you first met with
    him back in April of ‘05, isn’t it?
    A. That he attempted to sell the stock, yes.
    Q. Sir, the information that’s in here. Isn’t this precisely the information Mr.
    Nelson told you back in April of ’05?
    A. There may not have been all this detail, but generally that’s correct.”
    Later, Quarles & Brady’s counsel asked Gatziolis about his testimony regarding the letter.
    “Q. At any time up to the time this complaint was filed on the next to last day of
    April 2005, had Mr. Nelson ever told you that he had reached an oral agreement that Mr.
    Curia had agreed to buy his shares and his shares only for $4.2 million?
    A. No, he did not.
    Q. Had he said something like that to you, is that something you would have
    recalled?
    A. It would be.”
    Viewed in light of Gatziolis’ other testimony, the portion highlighted by Nelson does not support
    his contention that Gatziolis admitted that he knew about the oral agreement for $4.2 million and
    that the trial court ignored that testimony. As Gatziolis testified, he “generally” knew the
    information in the letter, i.e., that Nelson wanted to sell his shares to Curia and that Fifth Third
    agreed to loan the money for the purchase, but he denied that Nelson ever told him that he and
    - 50 ­
    No. 1-17-1653
    Curia had reached an agreement for the sale of his shares, which was consistent with his other
    testimony on this issue.
    ¶ 140 Nelson also points to another portion of Gatziolis’ testimony that he contends constitutes
    an admission by Gatziolis that he knew about the oral agreement for $4.2 million in April 2005.
    After Gatziolis’ testimony clarifying his earlier testimony about the letter, Nelson’s counsel’s
    asked Gatziolis:
    “Q. I think you told us earlier today that right from the very beginning of your
    relationship or your meetings with Mr. Nelson, he basically told you what was in that last
    letter about having had a $4.2 million agreement and Mr. Curia reneged on it. Remember
    that testimony from this morning?
    A. Yes.”
    This testimony does not constitute an admission by Gatziolis that he knew about the $4.2 million
    agreement as Nelson contends, but is rather Gatziolis acknowledging that he recalled his
    testimony on this subject matter from earlier that day. Viewed in light of Gatziolis’ unequivocal
    testimony that Nelson did not tell him about the $4.2 million oral agreement, we cannot say that
    the portions of the Gatziolis’ testimony identified by Nelson render the trial court’s ruling
    contrary to the manifest weight of the evidence.
    ¶ 141 Nelson next contends that, in 2007 and 2008, Quarles & Brady filed pleadings in the
    district court asserting that Curia and Nelson had entered into a $4.2 million oral agreement in
    2004. Nelson asserts that the evidence shows that Quarles & Brady did not have any additional
    information about the oral agreement at that time than it did when the original complaint was
    filed in April 2005. This is demonstrably false. The evidence shows that after the district court
    ruled in 2006, both Nelson and Korey emailed Shifflett to inform him about the $4.2 million oral
    - 51 ­
    No. 1-17-1653
    agreement. Nelson emailed Shifflett in August 2006, stating that he and Curia negotiated and
    agreed to a price of “4.2m (stock only, both corps),” but then Curia decided that he did not want
    to pay that much. Shifflett testified that this email was the first time he had received any
    communication about a potential oral agreement for $4.2 million. Similarly, Korey emailed
    Shifflett in November and December 2006 and stated that in November 2004, Nelson, Curia, and
    Debes “had a meeting where [Curia] agreed to pay 4.2 million [for] the stock.” Korey suggested
    that Quarles & Brady add such a claim to the impending motion. In addition, Shifflett testified
    that in early 2008 Nelson told him about an email he had received from Thomas where she stated
    that it was Toyota’s understanding that the stock purchase agreement included both Plaza and
    Mall and was for $4.2 million. Thus, the record shows that Quarles & Brady had significantly
    more information about a potential oral agreement in 2007 and 2008 than it did when it filed the
    original complaint in April 2005 or by the time the district court ruled in February 2006.
    Accordingly, we find that the circuit court’s holding that Quarles & Brady did not know about
    Nelson’s claim for a $4.2 million oral agreement before the district court ruled was not against
    the manifest weight of the evidence.
    ¶ 142 2. The Circuit Court’s Finding that Nelson Failed to Prove that it Was More Likely Than
    Not that Nelson Would Have Prevailed on a Breach of Contract Claim for the
    $4.2 Million Oral Agreement Was Not Against the Manifest Weight of the
    Evidence.
    ¶ 143 Although we have already found that the circuit court did not err in ruling that Quarles &
    Brady did not know about the oral agreement for $4.2 million before the district court ruled, we
    also find that even if Nelson had shown that Quarles & Brady did know about the agreement, his
    legal malpractice claim would nonetheless fail because he failed to establish the proximate cause
    element of this claim. That is, Nelson has failed to establish the “case within a case” aspect of his
    legal malpractice action. See Orzel v. Szewczyk, 
    391 Ill. App. 3d 283
    , 290 (2009). Nelson’s claim
    - 52 ­
    No. 1-17-1653
    is fundamentally that he would have prevailed on a breach of oral contract action against Curia if
    Quarles & Brady had properly investigated and raised the claim of an oral agreement in the
    Underlying Litigation. In order prevail on a claim for breach of contract, a plaintiff must prove
    (1) the existence of a contract, (2) the performance of the conditions precedent, (3) breach by
    defendant, and (4) damages as result of the breach. Van Der Molen v. Washington Mutual
    Finance, Inc., 
    359 Ill. App. 3d 813
    , 823 (2005). Here, Nelson has failed to establish even the
    existence of a contract.
    ¶ 144 In contending that he would have succeeded on a breach of contract claim in the
    Underlying Litigation, Nelson asserts that the uncontradicted evidence shows that he and Curia
    entered into an enforceable oral agreement for the sale of his shares only for $4.2 million. He
    maintains that the agreement for retirement benefits or “perks” was a separate agreement, and
    not a condition to the stock sale agreement. Nelson asserts that Curia’s testimony and
    contemporaneous conduct, Joyce’s testimony, and the evidence available from the automobile
    manufacturers and Fifth Third demonstrates that he would have prevailed on this claim in the
    district court if Quarles & Brady had investigated and raised this claim.
    ¶ 145                             a. Agreement for Shares Only
    ¶ 146 As a threshold matter, we observe that the record does not support Nelson’s contention
    that the oral agreement Nelson contends existed was for the “stock only” and that the retirement
    benefits or perks were a separate agreement. Nelson contends that the oral agreement for the sale
    of Nelson’s shares for $4.2 million was already in existence when Nelson approached Curia
    regarding the retirement benefits. Thus, Nelson contends that Curia’s refusal to provide the
    retirement benefits has no bearing on Curia’s acceptance of the stock sale agreement. Nelson
    - 53 ­
    No. 1-17-1653
    asserts that the documentary evidence and Curia and Nelson’s testimony support his claim that
    the agreements were separate.
    ¶ 147 However, Nelson’s own statements support the proposition the stock purchase agreement
    and the retirement benefits or perks agreement was one agreement. For instance, in the
    Chronology, Nelson stated Curia had been “difficult” in extending to him the things he needed
    for retirement and putting together a “retirement package.” Nelson stated that he would be
    contacting the manufacturers even though there was “no reason” for him to send a letter of his
    “wish to sell until we have a [retirement] package put together.” In Curia’s response, he stated
    that he did not see anywhere in their “agreement” that he was required to provide Nelson with a
    retirement package. Curia testified that he was referring to their written agreements. Similarly, in
    the Johnson Letter, Nelson stated that when he approached Curia about selling his shares, he
    “gave him some conditions at that time for the purchase” (emphasis added), which included most
    of the nine items listed in the Stockholders’ Minutes. Again, in the March 14, 2005, letter Nelson
    sent to Curia, Nelson stated that in August 2004 he offered Curia the opportunity to purchase his
    stock in Plaza and Mall “upon certain terms and conditions” that were set forth in a letter Nelson
    left on his desk on December 3, 2004. Nelson represented that those terms and conditions were
    that the October 6, 2004, Stockholders’ Minutes, which outlined Nelson’s retirement package, be
    signed by both parties, that the newly agreed leases for the properties owned by CRANK be
    signed by both parties, and that the September 30, 2004, GM financial statement be used for the
    sale price.
    ¶ 148 Nelson reiterated that the stock sale offer and the retirement package were one agreement
    in his subsequent correspondences with Quarles & Brady. For instance, in Nelson’s April 27,
    2005, email to Gatziolis, Nelson stated that the $4.2 million figure would “perhaps being the
    - 54 ­
    No. 1-17-1653
    selling price including all the perks.” (Emphasis added.) Similarly, in Nelson’s April 29, 2005,
    email to Gatziolis, Nelson identified the issues that he believed needed to be addressed, including
    a “Stock Sale which includes some type of Retirement Package.” (Emphasis added.) Again, in a
    September 17, 2005, email to Shifflett, Nelson stated that when he approached Curia about
    retiring in July 2004, he put together a retirement package. In fact, both Gatziolis and Shifflett
    testified that they believed that Nelson would not accept a settlement offer or sell his shares
    without a retirement package. Nelson’s correspondences support that conclusion. Nelson did not
    indicate his belief that the purported oral agreement was for the sale of stock only until his email
    to Shifflett and Cahill on August 29, 2006. Even in that email, Nelson stated that when he and
    Curia began negotiating in 2004, they used the 2000 agreement as “base” and then “began
    adding other perks.”
    ¶ 149 The fact that Curia did not sign the Stockholders’ Minutes is further evidence that the
    proposed stock sale and the retirement package were one agreement. The Stockholders’ Minutes
    were prepared one day before the Directors’ Resolutions, which Curia did sign, and contained
    the conditions of Nelson’s “retirement package.” Curia testified that he did not sign the
    Stockholders’ Minutes because he “agreed to buy the stock but not all the additional conditions
    that were listed.” Nelson also testified that Curia refused to sign the Stockholders’ Minutes
    because Curia believed it was “too much.” Clearly, if both Curia and Nelson believed that there
    was already an agreement for the sale of stock alone, the parties would have followed through on
    the stock purchase and handled the retirement package in a separate agreement. Instead, the
    evidence suggests that Nelson conditioned the stock sale on Curia providing a retirement
    package and Curia did not agree to those terms. In any event, the circuit court’s determination
    that the proposed stock sale and retirement package were one agreement was not against the
    - 55 ­
    No. 1-17-1653
    manifest weight of the evidence, given the ample evidence discussed above indicating that they
    were one agreement. Accordingly, we find that the circuit court did not err in finding that Nelson
    would not have prevailed on a breach of contract claim in the Underlying Litigation where the
    evidence shows that Nelson’s offer to Curia was to purchase the stock and provide a retirement
    package, and Curia did not accept. Even if we were to find that Nelson had adequately proved
    that the purported oral agreement was for the sale of his stock only, we would nonetheless find
    that Nelson failed to establish that it would be more likely than not that he would succeed on this
    claim before the district court for the reasons discussed below.
    ¶ 150                  b. Curia’s Testimony and Contemporaneous Conduct
    ¶ 151 Nelson first contends that Curia acknowledged at trial that he entered into an agreement
    with Nelson for the sale of the shares only, and his contemporaneous conduct at the time of the
    agreement represents evidence of the agreement. Nelson points to Curia’s testimony regarding
    his perception of their agreement in October 2004, at the time they signed the Directors’
    Resolutions.
    “Q. So by the time you signed [the Directors’ Resolutions] *** you know what it
    was at that time?
    A. Sure.
    Q. And then you told us that you proceeded after, so you had an agreement as of
    that date to buy the shares only?
    A. I believed I had an agreement.”
    Curia’s testimony illustrates that at the time he signed the Directors’ Resolutions, he believed
    that he had an agreement to buy Nelson’s shares for a “sum certain.” Nelson contends that this
    constitutes an admission by Curia that they had entered into an agreement for the purchase of
    - 56 ­
    No. 1-17-1653
    Nelson’s stock only. Under questioning from Quarles & Brady’s counsel, however, Curia
    testified that the agreement that he believed was in place at the time he signed the Directors’
    Resolutions in October 2004 was an agreement under the terms of the 1989 SPA and the “written
    agreements that [they] had *** in place for years,” i.e., the 1989 SPA, the 1993 Modification,
    and the 2000 Agreement. In fact, when asked directly about the oral agreement, Curia denied that
    he had ever accepted to buy Nelson’s shares for $4.2 million.
    “Q. And, sir, is it true that at no time in the year 2004 did you ever agree to pay
    Mr. Nelson $4.2 million for his shares as an agreement, an oral agreement, separate from
    what the 1989 stock purchase agreement was?
    A. Absolutely never.”
    ¶ 152 Curia’s contemporaneous conduct also does not support Nelson’s contention that he and
    Curia entered into an oral agreement for the purchase of Nelson’s shares only. First, the Fifth
    Third commitment letter does not serve as proof of an oral agreement. Curia testified that he
    intended to use the funds to purchase Nelson’s shares pursuant the 1989 SPA and for working
    capital or to pay off other loans. Debes testified, however, that based on the terms of the loan
    commitment, Curia could use the funds only to purchase Nelson’s shares. He testified, however,
    that when he met with Curia and Nelson in September 2004, he understood that they had not
    reached an agreement and that they were still negotiating toward a deal because they had
    different views about an acceptable price for the shares. Debes testified that it was common in a
    situation like Curia and Nelson’s for one party to get preapproval for a loan before the final
    terms of the agreement were established. Thus, Curia applying for and receiving a loan
    commitment from Fifth Third does not serve as proof of an oral agreement.
    - 57 ­
    No. 1-17-1653
    ¶ 153 Similarly, Curia’s contact with the automobile manufacturers does not indicate that the
    parties entered into an oral agreement. Nelson contends that the record shows that Curia
    submitted documentation to the automobile manufacturers for approval of the agreement
    demonstrating that they had, in fact, reached an agreement. However, the record shows that
    Curia began submitting documentation in anticipation of exercising his 1989 SPA options. Curia
    sent his response to the Chronology on November 4, 2004, indicating his intent to exercise his
    options. That same day he received the loan commitment letter from Fifth Third. On November
    3, 4, and 10, Curia submitted documentation to the automobile manufacturers, including the
    Toyota Minimum Standards, the Toyota Dealer Performance Evaluation, Dealer Biographical
    Information, and an Application for Nissan Dealer Sales and Service Agreement. On November
    4, 2004, Curia also submitted an Investment Proposal Summary to GM, to which he attached the
    letter from Fifth Third committing to the $4.2 million loan. Curia’s contemporaneous conduct
    therefore suggests that there was no previous agreement, and that he started seeking
    manufacturer approval only after he notified Nelson of his intent to exercise his options under
    the 1989 SPA. Thus, Curia’s testimony and contemporaneous conduct does not support Nelson’s
    contention that he would have prevailed on his claim for an oral agreement if it had been raised
    in the district court.
    ¶ 154                                c. Joyce’s Testimony
    ¶ 155 Nelson next contends that his expert, Joyce, testified that it was more probably true than
    not that Nelson would have won a breach a contract claim for breach of oral agreement if
    Quarles & Brady had pursued such a claim in the district court. Joyce acknowledged that at his
    deposition he opined that Nelson’s odds of success on this claim were “60/40.” Nelson claims
    that Quarles & Brady failed to elicit an opinion from their expert, DiVito, on this issue and
    - 58 ­
    No. 1-17-1653
    “effectively conceded” Joyce’s opinion that Nelson would have prevailed. The record shows,
    however, that Quarles & Brady did, in fact, elicit an opinion from DiVito on this subject, and his
    opinion contradicted Joyce’s.
    “Q. Sir, do you have an opinion whether the documentary information provided to
    Quarles and Brady by Mr. Nelson demonstrated approvable [sic] oral agreement for the
    sale of those shares?
    ***
    A. That the documents do not establish such an agreement.
    Q. What is that opinion based on?
    A. From the very beginning before [Quarles & Brady] even talked to [Nelson], he
    was bemoaning the fact that Curia would not negotiate with him, that he said no to
    everything. And although he continued negotiating, he never agreed to anything and there
    is no reference whatsoever to a specific oral agreement.”
    Thus, DiVito did contradict Joyce’s testimony on this issue, testifying that the evidence did not
    show a provable oral agreement for the sale of the shares, i.e., that Nelson would not have
    prevailed on this claim before the district court. It is well settled that “ ‘[a]s the trier of fact, the
    judge may accept one expert opinion over another.’ ” Robrock v. County of Piatt, 2012 IL App
    (4th) 110590, ¶ 42 (quoting City of Marseilles v. Radke, 
    307 Ill. App. 3d 972
    , 977 (1999)). Here,
    the circuit court plainly accepted DiVito’s testimony on this issue. Such a decision was within
    the discretion of the circuit court, and we cannot say, based on Joyce’s testimony and the other
    evidence presented, that the circuit court’s ruling was against the manifest weight of the
    evidence.

    No. 1-17-1653
    ¶ 156                             d. Automobile Manufacturers
    ¶ 157 Nelson next contends that the evidence provided by the automobile manufacturers proved
    the existence of the oral agreement for $4.2 million. Nelson asserts that the evidence
    demonstrates that in October 2004, both Nelson and Curia applied to the automobile
    manufacturers for approval of the stock sale. Nelson points out that both Zangri and Nour
    testified that the manufacturers will not process an application for the sale of shares unless the
    parties notify them that they have entered into an agreement. Nelson contends that the crucial
    piece of evidence demonstrating the existence of the oral agreement is Thomas’s email to
    Nelson, in which she stated that her notes showed that Curia informed Toyota that he had
    reached an agreement to purchase Nelson’s shares for $4.2 million.
    ¶ 158 At trial, Thomas acknowledged sending Nelson an email stating that the purchase price to
    Toyota’s “understanding” was $4.2 million, but she acknowledged that she did not know the
    source of that figure. She testified that there would likely be some sort of documentation to
    support the information in her email, but she did not have a purchase agreement and had no
    personal knowledge of what happened between Zangri and Nelson or Curia when the process
    began in October and November 2004. For his part, Zangri testified that he received the
    Directors’ Resolutions and, based on those documents, made an “assumption” that Curia had
    negotiated a deal to buy out Nelson’s remaining shares. In fact, Thomas sent a letter to Nelson on
    January 13, 2005, showing that Toyota still needed a purchase agreement in order for Toyota to
    continue their evaluation of the proposed ownership change. Thus, neither Zangri nor Thomas
    provided corroborating documentation to establish the existence of the oral agreement for $4.2
    million. At most, Zangri offered an “assumption” that Curia and Nelson negotiated a deal, and
    Thomas offered a notation that Curia agreed to buy Nelson’s shares for $4.2 million. However,
    - 60 ­
    No. 1-17-1653
    Thomas had no personal knowledge of any such agreement and could not provide any evidence
    to support that figure or an agreement.
    ¶ 159 Similarly, Nour from Nissan testified that, based on his experience, there would need to
    be an asset purchase agreement to start the approval process, but he could not say whether one
    was provided in Curia and Nelson’s case. And, in fact, Nour testified that he had not seen any
    documentation that suggested that Nelson and Curia entered into an oral agreement for the sale
    of Nelson’s shares for $4.2 million. Although Nissan conditionally approved the proposed stock
    purchase agreement on December 21, 2004, their approval letter does not state a purchase price
    and is conditioned upon the receipt of additional documentation, including stock certificates and
    documentation from Fifth Third.
    ¶ 160 We further observe that in the October 28, 2004, letters that Nelson submitted to the
    automobile manufacturers, he informed them that he “proposes to sell” his shares to Curia, not
    that they had reached an agreement for the sale of his shares. Also, as discussed above, the fact
    that Curia submitted documentation to the automobile manufacturers, seeking approval for the
    stock sale, does not serve as evidence of the oral agreement where Curia submitted the
    documentation in anticipation of exercising his options and after informing Nelson of his intent
    to do so on November 4, 2004. Accordingly, we cannot say that the court’s ruling was against
    the manifest weight of the evidence based on the evidence available from the automobile
    manufacturers.
    ¶ 161                             e. Fifth Third Bank and Debes
    ¶ 162 Nelson finally contends that the evidence provided by Fifth Third and Debes proved the
    existence of the oral agreement for $4.2 million. Nelson acknowledges that Debes testified that
    Curia and Nelson did not tell him that they had an agreement in place, but contends that this
    - 61 ­
    No. 1-17-1653
    testimony is contradicted by Debes’ contemporaneous conduct and other testimony. Nelson
    asserts that the fact that Curia paid Fifth Third’s lawyers to prepare the documents relating to the
    $4.2 million loan proves the agreement was in place. Nelson notes that the loan documents
    provided that the funds were to be used for the purchase of Nelson’s shares and Debes testified
    that Curia could use the funds only for that the purpose. Debes also knew that the manufacturers
    would not process Nelson and Curia’s applications unless they had an agreement in place, and he
    sent loan documents to the manufacturers at Curia’s request to facilitate the approval process.
    ¶ 163 We initially observe that, like Curia’s other communications with the automobile
    manufacturers, Debes did not send the loan documentation to the automobile manufacturers until
    after Curia notified Nelson of his intent to exercise his options. This is consistent with Curia’s
    testimony that he needed to show the manufacturers that he had the funds necessary to purchase
    Nelson’s shares. Although Debes testified that it would be inconsistent with the purpose of the
    loan for Curia to use the funds for any purpose other than purchasing Nelson’s shares, he also
    testified that it was common a situation like Nelson and Curia’s for the buyer to get preapproval
    for a loan before the final terms of the agreement were worked out. Debes testified that while he
    was generating the loan documents, he understood that Curia and Nelson were still negotiating
    because they could not agree on a price for the shares.
    ¶ 164 Debes's testimony and the documentation from Fifth Third thus suggest that Curia and
    Nelson approached Debes in anticipation of reaching an agreement for the shares. Curia sought
    preapproval so that he would be able to show the manufacturers that he had the funds necessary
    to complete the purchase. After the parties were unable to come to an agreement about the price
    for the shares, Curia notified Nelson of his intent to exercise his options under the 1989 SPA.
    Curia directed Debes to send the loan documentation to the manufacturers to facilitate the
    - 62 ­
    No. 1-17-1653
    approval process. Debes did not testify that Nelson and Curia had reached an oral agreement, and
    none of the loan documentation otherwise references an agreement. Accordingly, we cannot say
    that the court’s ruling was against the manifest weight of the evidence based on the evidence
    available from Debes and Fifth Third.
    ¶ 165                                      f. Conclusion
    ¶ 166 Accordingly, we find that the circuit court did not err in finding that Nelson failed to
    establish the proximate cause aspect of his legal malpractice claim with regard to Nelson’s claim
    for an oral agreement for $4.2 million. The evidence suggests that the proposed agreement was
    for the sale of Nelson’s shares as well as the retirement package or perks and Nelson failed to
    establish Curia’s acceptance of his offers. Curia’s testimony and contemporaneous conduct does
    not suggest that he entered into an oral agreement to purchase Nelson’s shares only for $4.2
    million. Joyce’s expert testimony was contradicted by DiVito, who testified that Nelson would
    not have been able to demonstrate a provable oral agreement in the Underlying Litigation, and it
    was within the circuit court’s discretion to accept DiVito’s testimony. In addition, the evidence
    from third parties—the automobile manufacturers, Debes, and Fifth Third—did not establish the
    existence of an oral agreement. We therefore find that the circuit court’s ruling that Nelson failed
    to establish that it was more likely than not that he would have succeeded on a breach of contract
    claim before the district court was not against the manifest weight of the evidence.
    ¶ 167                       C. Quarles & Brady’s Litigation Strategy
    ¶ 168 Nelson next contends that the circuit court erred in rejecting his claims that Quarles &
    Brady was negligent for failing to assert two defenses to Curia’s action for specific performance.
    Nelson asserts that Quarles & Brady should have raised a claim that Curia’s Option Exercises
    were invalid because they were not the mirror image of the options in the 1989 SPA and should
    - 63 ­
    No. 1-17-1653
    have argued that the parties’ written agreements were ambiguous. Nelson contends that had
    Quarles & Brady raised these arguments before the district court, they would have been
    successful and would have defeated Curia’s Option Exercises. Nelson further asserts that the
    circuit court erred in finding that Quarles & Brady’s negligence in failing to raise these claims
    did not proximately cause his damages because he settled the case after the Seventh Circuit’s
    remand where there was no practical alternative and continued litigation was unnecessary to
    preserve his legal malpractice claim.
    ¶ 169 As a threshold matter, we observe that Illinois law “distinguishes between negligence and
    mere errors of judgment.” Shanley v. Barnett, 
    168 Ill. App. 3d 799
    , 803 (1988). The question of
    whether an attorney has exercised a reasonable degree of care and skill is one of fact, and expert
    testimony is generally required to establish the standard of care against which to measure the
    attorney’s conduct. See Barth v. Reagan, 
    139 Ill. 2d 399
    , 407 (1990). 2 Here, both parties
    presented expert testimony regarding whether Quarles & Brady’s litigation decisions deviated
    from the standard of care.
    ¶ 170 1. The Circuit Court Did Not Err in Finding that Quarles & Brady Did Not Deviate from
    the Standard of Care in Not Raising a Claim that Curia’s Option Exercises Were
    Ineffective Because They Were Not the Mirror Image of the Options in the 1989
    SPA.
    ¶ 171 Nelson first contends that Quarles & Brady was negligent in failing to challenge Curia’s
    Option Exercises by arguing that the number of shares he sought to purchase in his Option
    Exercises did not match the number of shares listed in the 1989 SPA options. As an example,
    2
    We observe that there is a generally recognized exception to the rule requiring expert testimony
    to establish the standard of care “where the common knowledge or experience of lay persons is extensive
    enough to recognize or infer negligence from the facts, or where an attorney’s negligence is so grossly
    apparent that a lay person would have no difficulty in appraising it.” 
    Barth, 139 Ill. 2d at 407
    . We find,
    however, that this exception is not applicable to the case at bar and expert testimony was necessary to
    establish the standard of care.
    - 64 ­
    No. 1-17-1653
    Nelson points out that the 1989 SPA provided Curia with a second option to purchase 2009
    shares of Plaza, but Curia’s March 2, 2005, option exercise letter sought to purchase only 193
    shares. Nelson asserts that Curia’s March 3, 2005, option exercise was similarly defective
    because Curia “demanded” that Nelson sell his interest in Plaza’s land and buildings, but the
    1989 SPA provided that Curia must offer to purchase the land and buildings.
    ¶ 172 Under second option in the 1989 SPA, Curia could purchase 2009 shares of stock of
    Plaza and 300 shares of Mall, “which shares with previous purchased shares would represent
    49% of the issued and outstanding shares of capital stock in said corporations.” The third option
    provided that “[a]fter exercising the first two options to purchase as provided in this Agreement,
    [Curia] shall have a third option to purchase from [Nelson] the remaining 4,171 shares of stock
    in [Plaza] and 612 shares of stock in [Mall] provided that [Curia] also offer to purchase the land
    and four buildings of the [Plaza] dealership *** at its appraised value.”
    ¶ 173 In his March 2, 2005, option exercise notices, Curia stated that the second option in the
    1989 SPA “gives me the right to purchase from you an additional number of shares of capital
    stock of [Plaza] and [Mall] that would give me 49% of the outstanding capital stock of each
    Corporation, which I calculate to equal 193 shares and 170 shares, respectively.” In his March 3,
    2005, option exercise, Curia sought to purchase Nelson’s remaining shares in Plaza and Mall and
    offered to also purchase Plaza’s land and buildings in accordance with the third option in the
    1989 SPA.
    ¶ 174 Joyce testified that a reasonably careful lawyer, seeking to prevent Curia from exercising
    the options in his March 2005 Option Exercises, would have raised the argument that Curia’s
    Option Exercises were defective because they were not a mirror image of the options in the 1989
    SPA as required by Illinois law. Joyce testified that as a result of the corporations’
    - 65 ­
    No. 1-17-1653
    recapitalization after the 1989 SPA, it would have been impossible for Curia to exercise his
    options under the terms of the agreement because the 1989 SPA did not permit the percentages
    or number of shares to be modified because of recapitalization. Joyce opined that if Quarles &
    Brady had raised an argument that Curia’s Option Exercises were defective because they were
    not a mirror image of the options in the 1989 SPA, it was more probably true than not that the
    argument would have “prevailed.”
    ¶ 175 Joyce acknowledged that Quarles & Brady did raise an argument before the district court
    that the Option Exercises were defective because Curia attempted to use the price formula in the
    1993 Modification rather than the formula provided by the options in the 1989 SPA, but that
    argument was rejected by the district court. Joyce testified that although Quarles & Brady made
    this mirror image argument, it included the wrong facts to support the argument, and should have
    raised the discrepancy in the number of shares.
    ¶ 176 In contrast, DiVito testified that the standard of care did not require Quarles & Brady to
    raise an alternative argument that Curia’s Option Exercises were defective because the number
    of shares he sought to purchase did not match the 1989 SPA. DiVito testified that the second
    option in the 1989 SPA provided Curia with the option to purchase a percentage of the remaining
    shares, 49%, and the third option permitted him to purchase the “remaining” shares, which is
    what Curia sought in his Option Exercises. DiVito also noted that, in his review of Quarles &
    Brady’s materials, a draft brief contained an argument that Curia’s Option Exercises were invalid
    because the number of shares he sought to purchase were different from the options in the 1989
    SPA. DiVito testified that the fact that this argument did not appear in the final draft of the brief
    suggests that Quarles & Brady made a judgment to not include this argument, which was
    reasonable and consistent with the standard of practice.
    - 66 ­
    No. 1-17-1653
    ¶ 177 The circuit court’s order demonstrates that it clearly accepted DiVito’s testimony on this
    issue and not Joyce’s. As discussed, it was within the province of the trial court to accept
    DiVito’s testimony over Joyce’s on this issue. See Robrock, 
    2012 IL App (4th) 110590
    , ¶ 42.
    The trial court is accorded such deference because it is in the best position to resolve conflicting
    testimony and observe the witnesses’ demeanor and determine their credibility. Radke, 307 Ill.
    App. 3d at 977 (citing Flynn v. Cohn, 
    154 Ill. 2d 160
    , 169 (1992)). Here, the court was required
    to weigh conflicting testimony from the expert witnesses. The court could also consider
    Shifflett’s testimony that he considered raising an argument regarding the discrepancy in the
    number of shares, but ultimately decided not to, as evidenced by the draft brief containing this
    argument. Shifflett testified that he did not raise the issue because the 1989 SPA options granted
    Curia the right to purchase “49%” and then the “remaining” shares and this language was echoed
    in Curia’s Option Exercises, as DiVito also acknowledged.
    ¶ 178 Nelson contends, however, that Shifflett testified that his decision to not raise this
    argument was based on McCarthy v. Johnson, 
    122 Ill. App. 3d 104
    (1983). Nelson asserts that
    there is no evidence that Quarles & Brady was aware of this case during Quarles & Brady’s
    representation of Nelson and that McCarthy does not even support Shifflett’s position, as Joyce
    testified. As discussed, the circuit court heard Shifflett’s testimony that he relied on McCarthy to
    support his decision and heard Joyce’s testimony that McCarthy did not support Shifflett’s
    position. The court also heard DiVito’s testimony that Quarles & Brady did not deviate from the
    standard of care in not raising a mirror image argument because the percentages listed in Curia’s
    Option Exercises matched the percentages listed in the 1989 SPA options, as Shifflett also
    testified. Thus, there was conflicting testimony on this issue and, as noted, in such situations we
    accord deference to the decisions of the circuit court.

    was ample evidence to support the circuit court’s conclusion, and we cannot say, based on the
    record before us, that circuit court’s decision was against the manifest weight of the evidence.
    ¶ 179 Finally, although not expressly addressed by either expert, Nelson contends that Curia’s
    attempt to exercise his third option was defective because he “demanded” that Nelson sell
    Plaza’s land and buildings rather than merely offering to purchase them as provided in the 1989
    SPA. In his March 3, 2005, option exercise notice, however, Curia noted that the third option
    “gives me the right to purchase your remaining shares of the Corporations; [sic] provided that I
    also offer to purchase the land and four buildings of [Plaza].” Curia then stated that he was
    giving notice of the exercise of his option to “purchase all of your remaining shares of capital
    stock in the Corporations and the Land and Buildings for the consideration and upon the terms
    set forth in the [1989 SPA] and the [1993 Modification].” This language does not suggest a
    “demand” that Nelson sell his interest in Plaza’s land and buildings, but rather shows Curia’s
    intent to comply with the terms of the 1989 SPA. Thus, there was no basis for Quarles & Brady
    to raise an argument concerning the Curia’s March 3, 2005, option exercise in the district court.
    ¶ 180 Even assuming, arguendo, that we determined that Nelson had adequately established
    that Quarles & Brady deviated from the standard of care in failing to raise this argument, we
    would nonetheless find that he failed to establish the proximate cause or “case within a case”
    element of his legal malpractice claim on this issue. Although Joyce testified that, in his opinion,
    it was more likely true than not that Nelson would have prevailed on this argument if Quarles &
    Brady had raised it before the district court, DiVito testified that such an argument would be
    meritless because Curia’s Option Exercises essentially comported with the 1989 SPA options by
    seeking to purchase “49%” and the “remaining” shares outstanding. As discussed, the circuit
    court accepted the testimony of DiVito over Nelson on this issue, and that is consistent with its
    - 68 ­
    No. 1-17-1653
    role as the trier of fact. The record also shows that the district court rejected a “mirror image”
    argument by Quarles & Brady regarding the formula for determining the price of the shares.
    Furthermore, as illustrated above, Nelson’s contention that Curia’s March 3, 2005, option
    exercise was defective because Curia “demanded” that Nelson sell Plaza’s land and buildings is
    similarly meritless. Accordingly, we cannot say that the circuit court’s ruling that Nelson failed
    to establish the proximate cause element of his legal malpractice claim with respect to this
    argument was against the manifest weight of the evidence.
    ¶ 181 2. The Circuit Court Did Not Err in Finding that Quarles & Brady Did Not Deviate from
    the Standard of Care in Not Raising a Claim that the Written Agreements Were
    Ambiguous.
    ¶ 182 Nelson finally contends that Quarles & Brady deviated from the standard of care in
    failing to argue that the written agreements were ambiguous. Nelson asserts that this argument
    would have defeated Curia’s motion for summary judgment because an ambiguous contract
    cannot be interpreted as a matter of law and therefore cannot be disposed of by summary
    judgment. Nelson maintains that if Quarles & Brady had raised this argument, the parties would
    have been permitted to enter extrinsic evidence showing that when Curia and Nelson entered into
    the 1993 modification, they intended to dissolve the options in the 1989 SPA. Nelson contends
    that Quarles & Brady also would have been able to introduce extrinsic evidence regarding the
    meaning of the word “subsequently” in Paragraph 5 of the 1993 Modification, and would have
    been able to question Curia about his understanding of that paragraph at a deposition.
    ¶ 183 As with the mirror image argument, the parties offered conflicting expert testimony on
    this issue. Joyce testified that reading Nelson and Curia’s written agreements together, there is no
    clear specification for how Curia could exercise his options. Joyce testified that if Quarles &
    Brady had argued ambiguity, it would have prevented a summary judgment ruling and the parties
    - 69 ­
    No. 1-17-1653
    could have introduced extrinsic evidence regarding what Curia believed when he entered into the
    agreements. Joyce opined that within a reasonable degree of certainty, an argument that the
    contracts were ambiguous would have prevailed.
    ¶ 184 In contrast, DiVito testified that it was reasonable under the circumstances for Quarles &
    Brady to argue that the agreements were not ambiguous. He opined that Quarles & Brady’s
    argument that Paragraph 5 of the 1993 Modification negated any unilateral right by Curia to
    exercise the options in the 1989 SPA was a reasonable one. DiVito further testified that there
    was no downside to arguing that the agreements were not ambiguous because the district court
    could find ambiguity regardless of what the parties claimed.
    ¶ 185 As discussed above, the circuit court was entitled to accept DiVito’s testimony over
    Joyce’s on this issue. The court also heard Shifflett’s testimony that he believed it was not in
    Nelson’s best interest to advance an argument that the agreements were ambiguous in the motion
    for summary judgment. Shifflett testified that he considered doing discovery on the issue of
    ambiguity, but believed that Quarles & Brady had a good basis to argue that the agreements were
    not ambiguous, given the language that Nelson and Curia used in them. Shifflett believed that it
    would not have been in Nelson’s best interest to spend money taking depositions to try to prove
    an ambiguity.
    ¶ 186 Nelson contends, however, that if Quarles & Brady had raised a claim that the
    agreements were ambiguous, it could have challenged Curia’s assertion that, in Paragraph 5 of
    the 1993 Modification, the parties intended to use the word “previously” instead of
    “subsequently.” The record shows, however, that Quarles & Brady did challenge this assertion in
    their briefing before the district court. In conjunction with arguing that the agreements were not
    ambiguous, Quarles & Brady contended that the court should not accept Curia’s interpretation of
    - 70 ­
    No. 1-17-1653
    Paragraph 5 of the 1993 Modification and should enforce the contract as written, which would
    require Curia to negotiate with Nelson if he wished to purchase his shares. Given the evidence
    presented, we cannot say that the circuit court’s findings “appear to be unreasonable, arbitrary, or
    not based on the evidence.” 
    Eychaner, 202 Ill. 2d at 252
    . Accordingly, we find that the circuit
    court’s ruling that Nelson failed to demonstrate that Quarles & Brady was negligent in deciding
    to not argue that the agreements were ambiguous was not against the manifest weight of the
    evidence.
    ¶ 187 We further find that Nelson has failed to establish the “case within a case” aspect of his
    legal malpractice claim with respect to his argument that Quarles & Brady should have raised a
    claim that the agreements were ambiguous. Nelson asserts that such an argument would have
    permitted Quarles & Brady to submit extrinsic evidence to show the parties’ intent with respect
    to the agreements, but Nelson did not identify any evidence in the circuit court or before this
    court in support of this claim. At trial, Joyce testified that Quarles & Brady may have been able
    to offer testimony from the person who drafted the contracts or the corporations’ accountants,
    but acknowledged that he did not know what these witnesses would say. Joyce also testified that
    Quarles & Brady could depose Curia, who might testify that he did not know what the word
    “subsequently” meant in Paragraph 5 of the 1993 Modification. Nelson also offered his own
    testimony that he and Curia intended to eliminate the 1989 SPA options when they entered into
    the 1993 Modification.
    ¶ 188 Contrary to Nelson’s testimony that he and Curia intended to abrogate the 1989 SPA
    options when they entered into the 1993 Modification, Curia’s conduct suggests otherwise. Most
    notably, Curia notified Nelson of his intent to exercise those options, once in November 2004
    and again in March 2005. On September 2, 2005, Curia submitted an affidavit in the district
    - 71 ­
    No. 1-17-1653
    court in which he averred that he did not believe that the 1993 Modification abrogated the 1989
    SPA options. Joyce identified some potential witnesses who could offer extrinsic evidence, but
    offered no testimony regarding what they might say and Nelson offered no other evidence to
    suggest that these potential witnesses could offer any admissible extrinsic evidence. Thus,
    Nelson has failed to identify any evidence, other than this own testimony, that could have been
    submitted as extrinsic evidence if Quarles & Brady had raised a claim that the written
    agreements were ambiguous in the district court. Accordingly, we find that the circuit court’s
    ruling that Nelson failed to establish the proximate cause element of his legal malpractice claim
    with respect to this argument was not against the manifest weight of the evidence. 3
    ¶ 189                                     III. CONCLUSION
    ¶ 190 For the reasons stated, we affirm the judgment of the circuit court of Cook County.
    ¶ 191 Affirmed.
    3
    We observe that the circuit court found that Nelson failed to establish the proximate cause
    element of this claim and that Quarles & Brady was negligent in failing to raise a claim that Curia’s
    Option Exercises were defective because they were not the mirror image of the 1989 SPA options. The
    circuit court found that Nelson elected to settle the case with Curia after the Seventh Circuit reversed and
    remanded the case and thus forfeited his right to pursue these claims on remand. Both parties addressed
    this issue in their briefs before this court; however, we find that it is unnecessary to examine this issue
    where we have determined that Nelson failed to establish the proximate cause element of these claims for
    the reasons discussed above. Although the circuit court did not rely on the factors identified by this court
    in rendering its judgment, we observe that we may affirm the circuit court’s ruling on any basis in the
    record, regardless of whether the circuit court relied on those grounds and regardless of whether the
    circuit court’s reasoning was correct. Leonardi v. Loyola University Chicago,
