    JUDGE MICHELE M. CHRISTIANSEN authored this Opinion, in
    which JUDGES DAVID N. MORTENSEN and RYAN M. HARRIS
    concurred.
    CHRISTIANSEN, Judge:
    ¶1     Eugene D. Bergmann and Karen Bergmann, now known
    as Karen Christensen, divorced by bifurcated decree in May
    2015. The trial court reserved several issues for trial, including
    the legal effect of a premarital agreement (the Premarital
    Agreement) the parties entered into in 2001 and a subsequent
    agreement they executed in 2011 (the 2011 Agreement). In
    January 2016, the trial court issued its amended findings of fact
    and conclusions of law, which addressed all of the remaining
    issues. Bergmann moved to alter or amend judgment, which the
    court denied. Bergmann now appeals from the denial of that
    motion. We affirm and remand for the limited purpose of
    Bergmann v. Bergmann
    calculating Christensen’s reasonable attorney fees incurred on
    appeal.
    BACKGROUND
    ¶2    Bergmann and Christensen married in 2001. Before they
    married, the parties executed the Premarital Agreement, which
    provides, in relevant part:
    4.02 Living Expenses. During their marriage, the
    parties shall establish a joint checking account
    which will be the fund used for basic family living
    expenses, such as home mortgage payments,
    public liability and content insurance, utilities,
    property taxes, property maintenance as to the
    primary residence . . . , together with food and
    similar basic living expenses. Each party shall
    make deposits to such joint checking account in
    such portions and such amounts as from time to
    time may be determined necessary by them for
    such purposes. Initially, the parties have
    determined that Eugene will contribute $4,000 per
    month and Karen will contribute $2,000 per month,
    plus Social Security payments received by her.[1]
    The parties recognize that each is able to make
    such contributions. . . . If the parties cannot agree
    as to the contribution to be made hereunder, each
    party shall bear the costs of his or her respective
    living expenses, unless one of the parties
    determines to pay more than his or her share
    which he or she shall be entitled to do.
    1. Christensen’s social security benefits averaged $2,000 per
    month.

    Bergmann v. Bergmann
    ¶3     After they married, the parties operated for years without
    referring to the Premarital Agreement. During the marriage, the
    parties agreed that they would contribute equally to the family
    budget, and they both contributed to the joint checking account
    for basic family living expenses. Consistent with that
    understanding, the parties tracked their contributions and
    withdrawals in a spreadsheet available to both of them. Over
    time, Christensen’s contributions were significantly larger than
    Bergmann’s. Bergmann acknowledged this fact in a November
    2010 email to Christensen, in which he stated that he was
    approximately $159,000 “in debt” to her.
    ¶4     Shortly after the 2010 email, Bergmann indicated to
    Christensen that he needed money to help pay the basic family
    living expenses. Because Christensen had paid more of the basic
    family living expenses over the years than Bergmann, she agreed
    to give Bergmann $20,000 only if Bergmann agreed to provide
    “some assurance that [she] would get paid back.” Bergmann
    suggested “that he would transfer [his] equity [in the parties’
    marital home] to [Christensen] upon the sale of the home.” On
    January 7, 2011, the parties entered into the 2011 Agreement,
    which provides,
    AGREEMENT
    January 7, 2011: It is agreed that Eugene Bergmann
    and Karen Bergmann share equal ownership in
    their home . . . . It is also agreed to that Eugene will
    assign an amount of his equity to Karen in the
    amount of 170,000 dollars. This . . . amount
    constitutes an[] approximate amount of additional
    joint expenditures that Eugene has agreed to and is
    owing to Karen. This exact amount will be verified
    at some time in the future in a spreadsheet which
    they will both come to a further mutual agreement
    on. This spreadsheet will then be memorialized
    into a more formal agreement to [supersede] this
    one.

    Bergmann v. Bergmann
    Two days later, Christensen deposited $20,000 into the parties’
    joint checking account, and Bergmann used the money to pay
    the basic family living expenses.
    ¶5     Christensen filed for divorce in 2014. The trial court
    entered a bifurcated decree of divorce, dissolving the marriage
    and reserving several issues for trial. The two primary issues at
    trial were (1) whether the Premarital Agreement required the
    parties to make equal contributions to the basic family living
    expenses, and (2) whether, under the terms of the 2011
    Agreement, Bergmann was required to assign to Christensen
    $170,000 of his initial one-half share of the proceeds from the sale
    of the parties’ marital home.
    ¶6     The trial court held a one-day bench trial, at which both
    parties testified. The court determined that the Premarital
    Agreement was an enforceable agreement but that Section 4.02
    of the Premarital Agreement “does not say that [Bergmann and
    Christensen] are each going to be exactly responsible for fifty
    percent of the basic family living expenses forever and through
    the life of the Premarital Agreement.” The court noted that
    throughout the marriage, the parties had “not worr[ied] about
    the technicalities of the Premarital Agreement. In fact, they
    operated for years without referring to a copy of it.” Although
    the parties had maintained a spreadsheet tracking their
    individual contributions to the joint checking account, the court
    found that “this practice of handling basic family living expenses
    did not create a substitute contract that obligated them to divide
    and pay basic family living expenses on a fifty-fifty basis
    forever.” The court found that during the course of the marriage,
    the parties had some disputes about who would pay for what,
    but the parties “work[ed] this out when they entered into the
    [the 2011 Agreement].”
    ¶7     The court observed that, in the 2011 Agreement, the
    parties acknowledged that Christensen had paid more of the
    basic family living expenses than Bergmann, that Bergmann
    owed Christensen “an unspecified amount” of money, and that
    20160217-CA                     4                
    2018 UT App 130
    Bergmann v. Bergmann
    Bergmann agreed to assign to Christensen $170,000 of his equity
    share in the parties’ marital home on this basis. The court then
    determined that the 2011 Agreement was an enforceable
    agreement, supported by consideration. Specifically, at
    Bergmann’s request, Christensen transferred $20,000 into the
    parties’ joint checking account to help pay past due and
    upcoming basic family living expenses, and, in return,
    Bergmann assigned to Christensen $170,000 of his share of
    equity in the marital home. The court ultimately concluded that
    the 2011 Agreement was not a modification to the Premarital
    Agreement but that it was “an additional, enforceable agreement
    anticipated by the Premarital Agreement.”
    ¶8      Accordingly, the court awarded Christensen $170,000
    from Bergmann’s initial one-half share of the proceeds from the
    sale of the marital home. The court also awarded Christensen her
    attorney fees incurred in connection with responding to a
    pretrial motion in limine Bergmann had filed, concluding that
    the motion was “frivolous and patently inappropriate.” The
    court determined that the parties were otherwise responsible for
    their own attorney fees and costs.
    ¶9     After trial, Bergmann moved to alter or amend the
    judgment pursuant to rule 59(a)(7) of the Utah Rules of Civil
    Procedure. See Utah R. Civ. P. 59(a)(7) (“[A] new trial may be
    granted to any party on any issue for any of the following
    reasons: . . . that the verdict or decision is contrary to law or
    based on an error in law.”). In his motion, Bergmann asserted
    that when the parties entered into the 2011 Agreement, “both
    parties believed that there was a contractual duty under [the
    Premarital Agreement] that they each pay 50/50 for all joint
    living expenses.” According to Bergmann,
    [i]nasmuch as the Court ruled that in fact there was
    no legal obligation for [Bergmann] to reimburse
    [Christensen] for 50% of all marital expenditures,
    where [the 2011 Agreement] was fundamentally
    based on the mutual mistake that there was a
    20160217-CA                    5               
    2018 UT App 130
    Bergmann v. Bergmann
    contractual obligation under [the Premarital
    Agreement] for a 50/50 responsibility of family
    living expenses, this contract should not be
    enforced by the Court.
    Bergmann also asserted that the 2011 Agreement was based on
    the parties’ mutual mistake regarding the amount Bergmann
    owed Christensen. Bergmann requested that the court “reverse
    its finding that [Christensen] receive[] $170,000 from [Bergmann]
    and order that [Christensen] return those funds to him.”
    Christensen filed a response to the motion to amend, asserting
    that Bergmann’s motion was “merely a rehash of closing
    argument.” She also requested her attorney fees incurred in
    “having to oppose [Bergmann’s] motion.”
    ¶10   The trial court denied Bergmann’s motion, stating:
    The arguments [Bergmann] has advanced are not
    new to the case. He does not seek to present new
    evidence. There was no[] surprise in the sense that
    evidence or theories were allowed to be presented
    at trial that could not have been anticipated by the
    parties in preparation for the trial. The Court
    disagrees with [Bergmann’s] characterization about
    the intent and understanding of the parties as they
    attempted to define their marital relationship
    through agreement and practice. The Court is
    satisfied that the ruling announced from the bench
    and memorialized in the subsequently prepared
    findings and decree are legally and factually
    correct.
    The court awarded attorney fees to Christensen related to the
    post-trial motion, concluding that Bergmann’s motion to amend
    “did not materially advance the matter and required a careful
    response from [Christensen’s] counsel.” Bergmann appeals.

    ISSUES AND STANDARDS OF REVIEW
    ¶11 Bergmann contends that the trial court abused its
    discretion when it denied his rule 59 motion to alter or amend.
    Within this argument, Bergmann asserts that the trial court erred
    when it ruled that the 2011 Agreement was enforceable, because
    the parties were operating under a mutual mistake of fact
    (1) that the Premarital Agreement required equal contributions
    and (2) regarding the amount Bergmann owed Christensen.

    discretion because the trial court, having heard the evidence,
    typically is in a better position to determine whether the grant or
    denial of a rule 59 motion is warranted.”

    ANALYSIS
    I. Mutual Mistake
    ¶13 Bergmann contends that the parties “entered into the 2011
    Agreement operating under a mutual mistake of fact” and that
    20160217-CA                     7                
    2018 UT App 130
    Bergmann v. Bergmann
    the trial court “erred when it did not rescind the 2011
    Agreement.”2 He first asserts that “the parties executed the 2011
    Agreement erroneously believing that the Premarital Agreement
    required them to equally contribute to basic living expenses.”
    Alternatively, he asserts that the parties entered into the 2011
    Agreement operating under a mutual mistake about the amount
    Bergmann owed Christensen.
    ¶14 “A mutual mistake occurs when both parties, at the time
    of contracting, share a misconception about a basic assumption
    or vital fact upon which they based their bargain.” Cantamar,
    LLC v. Champagne, 
    2006 UT App 321
    , ¶ 38, 
    142 P.3d 140
     (citation
    and internal quotation marks omitted). “Mutual mistake of fact
    2. Christensen contends that Bergmann “waived any possible
    mutual mistake argument” by failing to plead the defense with
    particularity in his response to Christensen’s petition for divorce.
    The record indicates that Bergmann raised the issue of mutual
    mistake at trial and that Christensen objected on the same basis
    she asserts now. The trial court stated:
    Well, I don’t want to say that [Bergmann is]
    necessarily going to prevail on those defenses, but
    the fact of the matter is [that] this is equity, and
    those defenses are largely equitable arguments. It
    comes down to what . . . can be argued as fair
    under the circumstances. So I’m not too exercised
    that they weren’t pled in advance. I’m not sure
    they apply in this case.
    In its amended findings of fact and conclusions of law, the court
    did not expressly rule on Bergmann’s mutual-mistake argument.
    But in denying Bergmann’s motion to alter or amend, which was
    based on the theory of mutual mistake, the court stated that
    Bergmann’s arguments “are not new to the case” and that his
    “evidence or theories were allowed to be presented at trial.”
    Because the trial court apparently considered Bergmann’s
    mutual-mistake defense, we are not persuaded by Christensen’s
    contention that Bergmann waived the defense.

    ,
    ¶ 11, 
    357 P.3d 7
    . The trial court did not explicitly address
    Bergmann’s mutual-mistake arguments in its amended findings
    of fact and conclusions of law, but in its denial of Bergmann’s
    motion to alter or amend judgment, the court “disagree[d] with
    [Bergmann’s]     characterization   about     the    intent    and
    understanding of the parties as they attempted to define their
    marital relationship through agreement and practice.”
    A.    Equal Contributions
    ¶15 Bergmann asserts that the parties entered into the 2011
    Agreement “because they believed the Premarital Agreement
    required equal contributions.” The trial court determined that
    section 4.02 of the Premarital Agreement “does not say that
    [Bergmann and Christensen] are each going to be exactly
    responsible for fifty percent of the basic family living expenses
    forever and through the life of the Premarital Agreement.”
    Bergmann does not challenge this finding on appeal; indeed, he
    “embraces that finding on appeal.” Instead, Bergmann
    challenges the court’s “next step,” i.e., the court’s determination
    that the 2011 Agreement was enforceable and its “implied[]”
    rejection of his mutual-mistake argument.
    ¶16 According to Bergmann, “[e]verything in this case is
    underpinned by the parties’ belief that the Premarital Agreement
    required equal contributions.” Bergmann asserts that he “clearly
    testified that he signed the 2011 Agreement because he believed
    the Premarital Agreement required him to contribute equally to
    basic family living expenses.” He further asserts that
    Christensen’s testimony demonstrated that she expected
    Bergmann to contribute equally to the basic family living
    expenses and that the only reason Christensen gave for that
    20160217-CA                     9               
    2018 UT App 130
    Bergmann v. Bergmann
    expectation “was the terms of the Premarital Agreement.” We
    are not persuaded.
    ¶17 To begin with, the evidence is, at best, conflicting as to
    whether the parties entered into the 2011 Agreement based on
    the mistaken belief that the Premarital Agreement required them
    to contribute equally to the family’s basic living expenses. See
    generally High Desert Estates LLC v. Arnett, 
    2015 UT App 196
    ,
    ¶ 14, 
    357 P.3d 7
     (“[W]e will not reweigh . . . conflicting evidence
    so long as there is evidence to support the trial court’s
    findings.”). Bergmann testified that at the time he entered into
    the 2011 Agreement, he believed he was “required to pay 50/50
    of all living expenses” and that the 2011 Agreement was a result
    of that mistaken belief. He further testified that he believed he
    was indebted to Christensen based upon the terms of the
    Premarital Agreement.
    ¶18 However, as Christensen correctly observes, Bergmann
    also testified that he entered into the 2011 Agreement as a form
    of estate planning:
    I signed [the 2011 Agreement] to essentially—in
    the event of my death, you know, that there would
    be no problem with [Christensen] to have the
    whole house. We had a $170,000 mortgage on the
    house still, and it, you know, seemed reasonable.
    Then we also, you know, didn’t have all our real
    numbers.
    So we just had an approximate . . . debt that
    was 159 or something like that, and we just
    assigned that number to it, so—in the event of
    something happening. Then at some future date
    we would do the hard work and sort of figure out
    what the real numbers were, the real contributions
    and that sort of thing; but it was based on a 50/50
    understanding.
    20160217-CA                    10               
    2018 UT App 130
    Bergmann v. Bergmann
    Additionally, Bergmann acknowledged at trial that shortly
    before the parties signed the 2011 Agreement, he had asked
    Christensen to put an additional $20,000 into the parties’ joint
    checking account and that, in the 2011 Agreement, he had agreed
    to assign to Christensen $170,000 of his equity share in the
    parties’ marital home.
    ¶19 Christensen’s testimony on the matter also does not
    unequivocally establish that she entered into the 2011
    Agreement based on an assumption that the Premarital
    Agreement required the parties to contribute equally to basic
    family living expenses. Indeed, although Christensen’s
    testimony demonstrates that she expected the parties to
    contribute equally to basic living expenses, Christensen never
    explicitly stated that this expectation was based on the
    Premarital Agreement. Rather, Christensen stated (1) she
    expected Bergmann to contribute equally from the start of their
    marriage; (2) Bergmann failed to meet that expectation, forcing
    her to contribute more to basic family living expenses; (3) she
    expected him to make her whole, and Bergmann had “sent [her]
    many messages that he would make [her] whole”; and (4) when
    Bergmann needed $20,000 and had not followed through on his
    promises to make her whole thus far, she required more
    assurance that she would get paid back.
    ¶20 In any event, regardless of the source of the parties’ belief
    that they were required to make equal contributions, the record
    demonstrates that the parties conducted their marriage with the
    understanding that they would contribute equally to basic
    family living expenses. The trial court found, and Bergmann
    agrees, that the parties operated for years without referring to
    the Premarital Agreement and that they did not worry about the
    technicalities of the Premarital Agreement. The trial court also
    found that the parties worked together to pay basic living
    expenses. The record bears this out—when Bergmann either
    could not or would not contribute to the basic family living
    expenses, Christensen rose to the occasion and paid those
    expenses so that the parties would not overdraw on their joint
    20160217-CA                   11               
    2018 UT App 130
    Bergmann v. Bergmann
    account. Additionally, throughout their marriage, the parties
    maintained a detailed spreadsheet related to the basic family
    living expenses, tracking transactions for the expenses from the
    joint checking account as well as from credit cards tied to their
    personal, separate funds. This practice of working together to
    pay basic living expenses and of keeping detailed records of
    their contributions demonstrates the parties’ understanding and
    expectation that they would contribute equally to basic living
    expenses.
    ¶21 Moreover, and perhaps most importantly, the fact that the
    parties understood that they would contribute equally (whether
    based on the Premarital Agreement or from their course of
    conduct throughout the marriage) does not undermine the
    legitimacy of the 2011 Agreement or the fact that, at the time the
    parties entered into the 2011 Agreement, they shared an
    understanding that Bergmann owed Christensen money and
    that Christensen needed to be made whole. The trial court found
    that in the 2011 Agreement the parties acknowledged that
    Christensen had paid more of the basic family living expenses
    than Bergmann and that there was an “unspecified amount” that
    Bergmann owed Christensen. The trial court determined that it
    was “because of this that [Bergmann] agreed in the [2011
    Agreement] to assign to [Christensen] $170,000 of his equity
    share in the marital home.” The court further determined that
    Christensen had transferred $20,000 into the joint checking
    account to help Bergmann pay past due and upcoming basic
    living expenses and that, in exchange, Bergmann had assigned
    $170,000 of his equity share of the parties’ home. The court
    concluded that the 2011 Agreement was enforceable as a
    separate agreement, that the agreement was supported by
    separate consideration, and that both parties had changed their
    position in reliance on the agreement. There is sufficient
    evidence in the record to support the court’s findings.
    ¶22 Specifically, the record demonstrates that when
    Bergmann needed the $20,000 and approached Christensen for
    help, both parties understood that Christensen had contributed
    20160217-CA                    12              
    2018 UT App 130
    Bergmann v. Bergmann
    more to the basic family living expenses than Bergmann.
    Christensen testified that early on in the parties’ marriage, she
    started contributing more when Bergmann “couldn’t or
    wouldn’t” contribute. She stated that when they had bills to pay,
    Bergmann “would have some reason why he couldn’t”
    contribute, and the burden was on Christensen to keep the joint
    account from being overdrawn. In his November 2010 email,
    Bergmann acknowledged that he was approximately $159,000
    “in debt” to Christensen, and he apologized for things “being
    more of a mess” on his side financially.
    ¶23 In testifying about the events that “led up to the
    execution” of the 2011 Agreement, Christensen testified that
    when Bergmann approached her about the $20,000, she had not
    been “seeing any results in [Bergmann] trying . . . to make [her]
    whole.” Consequently, before she was willing to give Bergmann
    the money, she sought “something more tangible than just a
    promise that [she] would be made whole.” Accordingly, the
    parties agreed that “if [Christensen] could have some assurance
    that [she] would get paid back,” she would make the $20,000
    deposit into the joint checking account. Christensen testified that
    Bergmann suggested that he transfer $170,000 of his equity share
    in the parties’ marital home in exchange for the $20,000. On
    January 7, 2011, the parties entered into the 2011 Agreement, in
    which Bergmann assigned his $170,000 equity share of the
    parties’ home to Christensen. Two days later, on January 9, 2011,
    Christensen deposited $20,000 into the parties’ joint checking
    account, and Bergmann used the funds to pay his obligations.
    ¶24 Bergmann has not demonstrated that the trial court’s
    findings regarding the 2011 Agreement lack evidentiary support
    or that those findings are clearly erroneous. Consequently,
    Bergmann has failed to demonstrate that the parties entered into
    the 2011 Agreement based on a mutual mistake of fact. We
    therefore conclude that the trial court did not err in enforcing the
    2011 Agreement, and did not abuse its discretion in denying
    Bergmann’s motion to alter or amend judgment on this basis.

    Bergmann v. Bergmann
    B.    The Amount Bergmann Owed
    ¶25 As an alternative to his first argument, Bergmann
    contends that “the parties entered into the 2011 Agreement
    operating under a mutual mistake about the amount Mr.
    Bergmann owed Ms. Christensen.”
    ¶26 The 2011 Agreement stated, in relevant part, that the
    $170,000 represented an
    approximate      amount     of    additional    joint
    expenditures that [Bergmann] has agreed to and is
    owing to [Christensen]. This exact amount will be
    verified at some time in the future in a spreadsheet
    which they will both come to a further mutual
    agreement on. This spreadsheet will then be
    memorialized into a more formal agreement to
    [supersede] this one.
    According to Bergmann, the parties entered into the 2011
    Agreement “believing that Mr. Bergmann’s debt to Ms.
    Christensen totaled $170,000,” but “the evidence adduced at trial
    shows that Mr. Bergmann . . . owed Ms. Christensen much less.”
    ¶27 In support of his claim that he owed Christensen less than
    $170,000, Bergmann observes that Christensen hired an
    accountant to help calculate the amount Bergmann owed and
    that the accountant determined that Christensen had contributed
    approximately $168,000 more than Bergmann to the parties’ joint
    account. Bergmann asserts that it is undisputed that the
    accountant’s figure “did not credit Mr. Bergmann for
    approximately $22,000 in federal tax withholdings” or “include
    approximately $41,000 of Mr. Bergmann’s contributions that
    Ms. Christensen     characterized    as    withdrawals,”      thus
    demonstrating that “Bergmann, did not, in fact, owe . . .
    Christensen $170,000.” Bergmann further asserts, without
    citation to the record, that he “presented undisputed evidence
    that [he] owed tens of thousands of dollars less than $170,000.”

    Bergmann v. Bergmann
    ¶28 The trial court found that, in the 2011 Agreement, the
    parties had acknowledged that Christensen had contributed
    more to the parties’ basic family living expenses than Bergmann
    and had acknowledged that Bergmann owed Christensen an
    “unspecified amount.” In its oral ruling, the court determined
    that the parties had “settled for $170,000” and that Christensen
    “took [$]170,000 to cancel what [Bergmann] owed at that point,
    and that made it even from then on.” The court ultimately
    concluded that Bergmann was required to pay Christensen the
    $170,000 they had agreed to in the 2011 Agreement. In so ruling,
    the court explicitly rejected both parties’ attempts to alter the
    $170,000 amount stated in the 2011 Agreement.
    ¶29 Specifically, at trial, Christensen testified that she had
    hired an accountant to help her determine the exact amount
    Bergmann owed her. Christensen described the information she
    had provided to her accountant and ultimately relied on the
    figures prepared by her accountant (and received as evidence by
    the trial court) to support her testimony regarding how much
    Bergmann owed her. Christensen’s accountant testified that
    Christensen had contributed approximately $336,000 more than
    Bergmann to the parties’ joint checking account and that
    Bergmann’s share of this difference was approximately $168,000.
    However, the court rejected both Christensen’s and her
    accountant’s testimony “about the family expenses,” stating that
    it “did not find [that testimony] to be particularly credible.” See
    generally Henshaw v. Henshaw, 
    2012 UT App 56
    , ¶ 11, 
    271 P.3d 837
    (“It is within the province of the trial court, as the finder of fact,
    to resolve issues of credibility.”). And with regard to the
    accountant specifically, the court found that his “conclusions
    and tables” were “tainted” by Christensen’s “assumptions and
    directions about what was a family expense [and] what was
    not.”
    ¶30 The court also rejected Bergmann’s testimony regarding
    several out-of-pocket expenses he had allegedly incurred in
    getting the marital home ready to sell and which he believed
    should offset his debt to Christensen. Bergmann testified that he

    2018 UT App 130
    Bergmann v. Bergmann
    had spent “101.25 hours” working on the parties’ marital home,
    totaling $4,716.85 in out-of-pocket expenses and “over $11,000”
    in labor. He also submitted numerous receipts into evidence. 3
    But the court found that Bergmann’s testimony was not
    “complete or credible enough.” The court explained that
    Bergmann was “vague and unspecific about [his] out-of-pocket
    expenses” and that it was hard to distinguish between the work
    that Bergmann did “that he normally would have contracted for
    and work that a homeowner would normally do to protect their
    own asset.” Concluding that Bergmann provided “[n]othing
    reliable” regarding the value of that work, the court
    “disregard[ed] that testimony.”
    ¶31 The resolution of this issue required the trial court to
    determine the credibility of each witness’s testimony. On appeal,
    we give great deference to a trial court’s
    determinations of credibility based on the
    presumption that the trial judge, having personally
    observed the quality of the evidence, the tenor of
    the proceedings, and the demeanor of the parties,
    is in a better position to perceive the subtleties at
    issue than we can looking only at the cold record.

     (citation and
    internal quotation marks omitted). “Consequently, in all actions
    tried upon the facts without a jury, findings of fact shall not be
    set aside unless clearly erroneous, and due regard shall be given
    to the opportunity of the trial court to judge the credibility of the
    witnesses.” 
    Id.
     (citation and internal quotation marks omitted).
    ¶32 Here, the record demonstrates that the trial court
    considered testimony by Christensen, Christensen’s accountant,
    3. The court received only twenty pages of Bergmann’s
    documentation into evidence, concluding that the rest was
    inadmissible.

    Bergmann v. Bergmann
    and Bergmann regarding the amount Bergmann owed
    Christensen, and it elected to disregard that testimony as not
    credible. Bergmann has failed to challenge the court’s credibility
    determination, much less demonstrate that it was clearly
    erroneous, and we will “defer to that credibility determination.”
    See id. ¶ 7. Moreover, although Bergmann asserts that the parties
    mistakenly believed that he owed Christensen $170,000, the trial
    court determined that the parties had “settled for $170,000,” i.e.,
    that the $170,000 amount represented a compromise between the
    parties. (Emphasis added.) Bergmann has not challenged this
    finding on appeal, and he has therefore failed to demonstrate
    that it is clearly erroneous. See Utah R. Civ. P. 52(a)(4) (“Findings
    of fact . . . must not be set aside unless clearly erroneous, and the
    reviewing court must give due regard to the trial court’s
    opportunity to judge the credibility of the witnesses.”). By
    extension, he has failed to demonstrate that the 2011 Agreement
    was the product of a mutual mistake.
    ¶33 In any event, the fact that the 2011 Agreement
    contemplated that the parties could revisit the amount stated
    indicates that the parties did not necessarily agree on the amount
    Bergmann owed (as opposed to their definite agreement that
    Bergmann did, in fact, owe Christensen something), but that
    they settled on $170,000 for the time being, reserving the right to
    revisit the issue in the future if they truly perceived that
    Bergmann owed Christensen a different amount. Yet in the more
    than three years between the execution of the 2011 Agreement
    and Christensen’s filing for divorce, the parties never revisited
    the issue, and both parties ultimately failed to present any
    credible evidence in their respective efforts to alter the amount
    Bergmann owed.
    ¶34 Bergmann has not demonstrated that the 2011 Agreement
    was the product of a mutual mistake as to the amount he owed.
    Consequently, the trial court did not err in enforcing the 2011
    Agreement, nor did it abuse its discretion in denying
    Bergmann’s motion to alter or amend judgment.

    Bergmann v. Bergmann
    II. Attorney Fees
    ¶35 Christensen contends that she “is entitled to the fees and
    costs she has incurred in defending against [Bergmann’s]
    appeal.” “Generally, when the trial court awards fees in a
    domestic action to the party who then substantially prevails on
    appeal, fees will also be awarded to that party on appeal.”
    Osguthorpe v. Osguthorpe, 
    872 P.2d 1057
    , 1059 (Utah Ct. App.
    1994) (citation and internal quotation marks omitted). The trial
    court awarded Christensen her attorney fees incurred in
    responding to Bergmann’s motion to alter or amend judgment,
    concluding that Bergmann’s motion “did not materially advance
    the matter and required a careful response from [Christensen’s]
    counsel.” 4 Bergmann has not challenged the trial court’s
    attorney-fee award, and Christensen correctly observes that
    Bergmann’s arguments on appeal are “nearly identical” to those
    he presented in his motion. Accordingly, because Christensen
    has prevailed on appeal, we award Christensen her reasonable
    attorney fees incurred in connection with this appeal in an
    amount to be determined by the trial court on remand. 5
    CONCLUSION
    ¶36 We affirm the trial court’s ruling that the 2011 Agreement
    was enforceable and not the product of a mutual mistake. We
    4. At trial, the court also awarded Christensen her attorney fees
    incurred in responding to Bergmann’s motion in limine,
    concluding that Bergmann’s motion in limine was “frivolous and
    patently inappropriate.” The court determined that the parties
    were otherwise responsible for their own attorney fees and costs.
    5. Utah Rule of Appellate Procedure 34(a) provides that “if a
    judgment or order is affirmed, costs shall be taxed against [the]
    appellant unless otherwise ordered.” We therefore also award
    Christensen her costs reasonably incurred on appeal.

    therefore conclude that the trial court did not abuse its discretion
    in denying Bergmann’s motion to alter or amend judgment. We
    remand this case to the trial court for the limited purpose of
    calculating Christensen’s attorney fees reasonably incurred on
    appeal.
