    JANINE LESUEUR v. ANDREW LESUEUR
    (AC 39759)
    Lavine, Prescott and Eveleigh, Js.
    Syllabus
    The plaintiff, whose marriage to the defendant previously had been dis-
    solved, appealed to this court from the judgment of the trial court
    granting the defendant’s motion for a modification of custody and child
    support, and denying her motion for a modification of unallocated ali-
    mony and child support. Held:
    1. The trial court improperly granted the defendant’s motion to modify child
    support, as the court’s factual findings regarding the plaintiff’s income
    were clearly erroneous: there was no legally proper evidentiary basis
    before the court to support its determination of the plaintiff’s gross or
    net weekly income at the time it considered the motions for modification,
    as the court calculated the plaintiff’s child support share on the basis
    of her income that included alimony, which is not permitted by our
    child support statutes or regulations, and although the defendant claimed
    that any error was harmless and had a de minimis impact on the court’s
    order that the plaintiff pay him weekly child support in that the difference
    between the child support the court ordered the plaintiff to pay and
    what an accurate determination of her weekly income required her to
    pay may not have been great, the evidentiary basis of the court’s order
    was unclear and the error was harmful, as the plaintiff’s presumptive
    share of support may have been less than the court’s order had the
    court not included alimony in its calculation of the parties’ combined
    weekly income.
    2. The trial court did not abuse its discretion by terminating the defendant’s
    child support obligation retroactively to September 2, 2015: contrary to
    the plaintiff’s claim, that court did not lack sufficient information to
    calculate the parties’ financial circumstances as of September 2, 2015,
    as it had information pertaining to the parties’ financial circumstances
    in June, 2015, there was no evidence in the record indicating that the
    plaintiff’s financial circumstances had changed during the summer or
    fall of 2015, except that she no longer had custody of the parties’ son
    since August, 2015, and the plaintiff admitted that her full-time employ-
    ment did not change and her salary was not reduced until she filed the
    motion for modification of unallocated alimony and child support in
    February, 2016; moreover, the plaintiff failed to demonstrate that she
    required child support in order to provide for the necessary expenses
    of the parties’ son, as she presented no evidence that the defendant,
    who was the primary custodial parent, was not providing for their son’s
    necessary expenses for food, shelter and clothing, and certain of the
    expenses incurred by the plaintiff were typical of those incurred by any
    noncustodial parent during visitation or were voluntary, and not the
    necessary expenses contemplated by case law and statute.
    3. The trial court did not misconstrue the parties’ separation agreement;
    that court properly determined that the provision of the agreement
    regarding a cap and the tuition limit of a four year college degree from
    within the Connecticut state university system did not apply because
    the parties and their children had mutually agreed on the postsecondary
    institutions the children would attend, and the plaintiff’s construction
    of the agreement that after the family mutually agreed on the appropriate
    educational institutions for their children, the parties would not pay the
    cost of tuition that exceeded that of the cap would undermine the
    purpose of the agreement to have the parties and their children mutually
    agree on the appropriate postsecondary educational institutions the
    children should attend.
    4. The trial court did not abuse its discretion in denying the plaintiff’s motion
    to modify unallocated alimony and child support: although the plaintiff
    claimed that the trial court, which had determined that a reduction
    in her salary constituted a substantial change in circumstances, was
    obligated to consider all of the statutory (§ 46b-82) factors in ordering
    alimony in accordance with the needs and financial resources of the
    parties, the plaintiff failed to consider that the trial court stated that in
    ruling on the motion to modify unallocated alimony and child support
    it had considered the relevant statutes and case law and did not need
    to make explicit reference to the statutory criteria that it considered in
    making its decision; moreover, because the fundamental purpose of
    child support is to provide for the care and well-being of minor children,
    and child support follows the child, the plaintiff’s claim that the amount
    of money she received from the defendant was reduced due to the fact
    that she no longer was receiving child support for the parties’ daughter
    was unavailing, as the court found that the unallocated support the
    plaintiff was receiving continued to be sufficient to fulfill its intended
    purpose to equalize the income of the parties and support the children.

    Opinion
    LAVINE, J. In this postmarital dissolution appeal, the
    plaintiff, Janine LeSueur, appeals from the postjudg-
    ment orders of the trial court granting the motion for
    modification of custody and child support filed by the
    defendant, Andrew LeSueur, and denying her motion for
    modification of unallocated alimony and child support.
    Specifically, the plaintiff claims that the court, Tindill,
    J., (1) abused its discretion by granting the defendant’s
    motion to modify custody and child support because the
    child support order is predicated on clearly erroneous
    factual findings and because it terminated the defen-
    dant’s child support obligation retroactively without
    sufficient information to evaluate the parties’ financial
    circumstances, and without considering that she contin-
    ued to incur and pay expenses for the parties’ son from
    September 2, 2015, until the date of the hearing; (2)
    misconstrued the parties’ separation agreement
    (agreement) regarding the parties’ obligations to pay
    for their children’s postsecondary education; and (3)
    abused its discretion by denying her motion to modify
    unallocated alimony and support. We affirm in part and
    reverse in part the judgment of the trial court.
    The parties’ marital history previously was set forth
    in LeSueur v. LeSueur, 
    172 Conn. App. 767
    , 
    162 A.3d 32
    (2017), which concerned an appeal by the defendant
    from certain postjudgment motions (defendant’s
    appeal). The parties were married on November 28,
    1992, and divorced on January 27, 2011. 
    Id., 770. At
    the
    time of dissolution, ‘‘the parties had two minor children:
    a daughter, born in July, 1997; and a son, born in Janu-
    ary, 1999. The judgment of dissolution incorporated the
    parties’ separation agreement that provided that the
    plaintiff and the defendant would have joint legal cus-
    tody and the plaintiff primary physical custody of the
    two children. The separation agreement also provided
    . . . that the defendant . . . pay the plaintiff unallo-
    cated alimony and child support from March 1, 2011
    until June 30, 2020.’’ 
    Id. Subsequently, the
    defendant
    assumed primary physical custody, first of the parties’
    daughter; 
    id., 770–71; and
    then their son. The defen-
    dant’s appeal concerned issues related to child support
    for the parties’ daughter. The present appeal concerns
    child support related to their son, among other things,
    and is factually and procedurally distinct from the
    defendant’s appeal.
    The record in the present appeal reveals the following
    procedural history. On August 14, 2015, the defendant
    filed a motion to modify custody and child support,
    alleging in part that circumstances regarding custody
    of the parties’ son had changed substantially. The defen-
    dant represented that the parties had agreed that, as
    of July 31, 2015, their son would live with the defendant
    and have liberal visitation with the plaintiff.1 The defen-
    dant, therefore, asked the court to terminate his child
    support obligation to the plaintiff and to order the plain-
    tiff to pay him child support.2 On February 8, 2016, the
    court accepted the parties’ stipulation regarding the
    son’s custody change and scheduled a hearing on the
    issue of child support.
    On February 10, 2016, the plaintiff filed two motions
    for modification of certain provisions of the separation
    agreement. In one motion, she claimed that there had
    been a substantial change in her financial circum-
    stances due to a reduction in her employment and sal-
    ary. She, therefore, asked the court to increase the
    amount of unallocated alimony and child support she
    received from the defendant.3 In her second motion,
    titled ‘‘Motion for Modification of Children’s Expenses
    and Tuition, Postjudgment,’’ the plaintiff claimed that
    there had been a substantial change in her financial
    circumstances, and therefore, she asked the court to
    order the defendant to pay 100 percent of the educa-
    tional ‘‘add-on’’ expenses for their son and all costs
    associated with his private school tuition.4 (Internal
    quotation marks omitted.)
    The court heard argument on the parties’ motions on
    three days in the spring of 2016,5 and requested that
    the parties submit posthearing briefs. The court issued
    orders on the defendant’s motion to modify child sup-
    port on October 11, 2016. The court found that the
    parties’ son had been living with the defendant since
    the date he filed his motion to modify child support
    and that he had continued to pay the plaintiff child
    support in the amount of $996.27 per week since Sep-
    tember 1, 2015. The court granted the defendant’s
    motion to modify child support, thereby terminating his
    child support obligation to the plaintiff retroactive to
    September 2, 2015, and ordered the plaintiff to reim-
    burse the defendant for the child support that he had
    paid her while their son was living with him.
    On October 13, 2016, the court issued orders on the
    plaintiff’s motion for modification of alimony and sup-
    port and motion for modification of children’s expenses
    and private school tuition. The court found that the
    plaintiff’s salary had decreased since the time of dissolu-
    tion and that the decrease constituted a substantial
    change of circumstances. The court also found that
    the plaintiff’s monthly expenses had decreased since
    January 27, 2011. In addition, the court found that the
    pretax income from employment formulae used to cal-
    culate the amount of unallocated support the defendant
    was to pay the plaintiff continued to be sufficient to
    fulfill the intended purpose of equalizing the incomes
    of the parties and supporting the children. See footnote
    3 of this opinion. The court, therefore, denied the plain-
    tiff’s motion to modify unallocated alimony and child
    support.6
    Pursuant to the oral request of the parties’ counsel;
    see footnote 5 of this opinion; the court found that, had
    the family stayed intact, the parties more likely than
    not would have provided support for their children’s
    postsecondary education. It also found that the parties
    are well educated and have the income and assets to
    assist their children with the cost of higher education.
    The court found ample evidence of the children’s aca-
    demic commitment, preparedness, and athletic prow-
    ess. The parties mutually had agreed that their daughter
    should attend Princeton University and that their son
    should attend Dartmouth College.7 The court also con-
    cluded that, pursuant to the agreement, neither the
    ‘‘UConn cap’’ nor the cost of a four year degree within
    the Connecticut state university system was applicable.8
    The court, therefore, ordered the parties to ‘‘timely pay
    education support . . . to Princeton University and
    Dartmouth College’’ as required by paragraphs 7 (f) and
    13 (B) (iv) of the separation agreement. The plaintiff
    appealed.
    We begin with the well settled standard of review in
    family matters. ‘‘An appellate court will not disturb a
    trial court’s orders in domestic relations cases unless
    the court has abused its discretion or it is found that
    it could not reasonably conclude as it did, based on the
    facts presented. . . . In determining whether a trial
    court has abused its broad discretion in domestic rela-
    tions matters, we allow every reasonable presumption
    in favor of the correctness of its action.’’ (Internal quota-
    tion marks omitted.) Ferraro v. Ferraro, 
    168 Conn. App. 723
    , 727, 
    147 A.3d 188
    (2016).
    I
    The plaintiff’s first claim is that the court abused its
    discretion by granting the defendant’s motion to modify
    custody and child support because (1) its child support
    order is predicated on a clearly erroneous factual find-
    ing, and (2) it terminated the defendant’s child support
    obligation retroactively without sufficient information
    to calculate the parties’ financial circumstances as of
    September 2, 2015, and without considering that she
    continued to incur and pay expenses related to the son.9
    We agree that the court’s order that the plaintiff pay
    child support is predicated on a clearly erroneous fac-
    tual finding. We do not agree, however, that the court
    lacked sufficient information regarding the parties’
    financial circumstances as of September 2, 2015, or that
    the voluntary expenses the plaintiff incurred overcame
    the presumption that child support follows the child.
    The following additional facts are relevant to our
    resolution of this claim. As previously stated, as of July
    31, 2015, pursuant to the parties’ informal agreement,
    their son began to reside with the defendant. On August
    14, 2015, the defendant filed a motion for modification
    of custody and child support. He represented that there
    had been a substantial change in circumstances due to
    the fact that the parties’ son was living with him and
    requested that, because he had become financially
    responsible for their son, his child support obligation
    to the plaintiff be terminated and that the plaintiff be
    ordered to pay him child support. On February 8, 2016,
    the court accepted the parties’ stipulation that their son
    reside with the defendant and ordered a hearing to be
    held on the issue of child support.
    The parties appeared before the court for an eviden-
    tiary hearing on March 28, May 17, and June 1, 2016.
    At that time, the defendant argued that the change in
    the primary physical custody of the parties’ son required
    a modification of the child support portion of the unallo-
    cated support order because child support follows the
    child. He also argued that he had been paying the plain-
    tiff child support pursuant to the court’s July, 2015
    order that modified his child support obligation when
    he assumed custody of the daughter. The defendant
    contended that, as a matter of law and equity, he was
    entitled to be reimbursed by the plaintiff for the child
    support he had paid her since September 10, 2015, the
    date he served the plaintiff with the motion to modify
    child support.
    The plaintiff argued that the court should not modify
    the defendant’s child support obligation because the
    agreement called for unallocated alimony and child sup-
    port calculated on the basis of the defendant’s pretax
    income from employment and that alimony and child
    support should not be broken into separate amounts.10
    The plaintiff requested that, if the court granted modifi-
    cation of child support and did so retroactively, to order
    retroactivity from February 8, 2016, the date the transfer
    of custody was accepted by the court, not the date the
    defendant’s motion to modify was served. In addition,
    the plaintiff claimed she continued to incur expenses
    for their son after the motion was served.
    In its order, the court found, contrary to the plaintiff’s
    argument, that the defendant was not seeking to modify
    the term, duration, or the percentage of the unallocated
    support formulae set forth in paragraph 12 of the
    agreement, but was seeking a determination of the
    plaintiff’s child support obligation for the parties’ son
    who resided with him. The court also found that the
    defendant had demonstrated a substantial change in
    circumstances that justified a modification of child sup-
    port, i.e., the son was living full-time with him as of
    the date of the motion for modification was filed. The
    defendant had paid the plaintiff child support in the
    amount of $996.27 per week since September 1, 2015.
    The court, therefore, granted the defendant’s motion to
    modify child support and terminated his child support
    obligation retroactively to September 2, 2015. The court
    found that the defendant was entitled to reimbursement
    from the plaintiff in the amount of $57,783.66.
    The court found on the basis of the parties combined
    weekly income of $12,980 that the plaintiff’s presump-
    tive child support obligation for the parties’ son pursu-
    ant to the guidelines was $137 per week. The court,
    therefore, ordered the plaintiff to pay the defendant
    $137 per week in child support, commencing November
    1, 2016.
    A
    The plaintiff claims that the court improperly granted
    the defendant’s motion to modify child support and
    ordered her to pay the defendant child support on the
    ground that the court’s factual finding regarding her
    annual income is clearly erroneous because it improp-
    erly includes alimony and child support income. We
    agree.
    ‘‘Appellate review of a trial court’s findings of fact is
    governed by the clearly erroneous standard of review.
    The trial court’s findings are binding upon this court
    unless they are clearly erroneous in light of the evidence
    and the pleadings in the record as a whole. . . . A
    finding of fact is clearly erroneous when there is no
    evidence in the record to support it . . . or when
    although there is evidence to support it, the reviewing
    court on the entire evidence is left with the definite
    and firm conviction that a mistake has been committed.
    . . . Therefore, to conclude that the trial court abused
    its discretion, we must find that the court either incor-
    rectly applied the law or could not reasonably conclude
    as it did.’’ (Citation omitted; internal quotation marks

    ‘‘The [plaintiff] is entitled to relief from the trial
    court’s improper rulings only if one or more of those
    rulings were harmful. . . . It is well settled that the
    burden of establishing harm rests on the appellant. . . .
    To meet this burden in a civil case, the appellant must
    show that the ruling would likely affect the result.’’

    (2001).
    The following additional facts are relevant to our
    resolution of this claim. On March 29, 2017, after she had
    appealed, the plaintiff filed a motion for articulation;
    see Practice Book § 66-5; requesting, among other
    things, that the trial court articulate the basis of its
    calculation of the court’s child support guidelines work-
    sheet docket number 150.11 The court denied the motion
    for articulation, and the plaintiff filed a motion for
    review in this court. See Practice Book § 66-7. This
    court granted the motion for review and ordered the
    trial court to articulate, in relevant part, the following:
    (1) the factual basis for stating on worksheet number
    150 that the plaintiff’s gross weekly income was $5820
    and that her net weekly income was $3680; (2) whether
    the alimony received by the plaintiff was included in
    the calculation that determined the plaintiff’s gross
    income as stated on worksheet number 150; and (3)
    the factual basis for stating on worksheet number 150
    that the defendant’s net weekly income was $9301.
    In its articulation, the trial court stated that the factual
    basis for using $5280 as the plaintiff’s gross weekly
    income and $3680 as her net weekly income was the
    plaintiff’s May 17 and May 20, 2016 financial affidavits
    and her May 17, 2016 testimony. The court further stated
    that the alimony received by the plaintiff was not
    included in her gross income amount on worksheet
    number 150. Additionally, the court articulated that the
    factual basis for using $9301 as the defendant’s net
    weekly income was his May 17, 2016 financial affidavit
    and his testimony on May 17, 2016.
    On appeal, the plaintiff claims that in determining
    her annual income, the court erred by utilizing the infor-
    mation on the financial affidavit she submitted on May
    20, 2016, which included income in the form of ali-
    mony,12 and not the worksheets submitted by the parties
    at the hearing on May 17, 2016. The worksheet that the
    plaintiff submitted states that her gross weekly income
    is $1827 and her net weekly income is $1332. The work-
    sheet that the defendant submitted states that the plain-
    tiff’s gross weekly income is $2697 and her net weekly
    income is $2141. Neither of the worksheets submitted
    by the parties included alimony income to the plaintiff.
    In October, 2016, when the court issued its decisions on
    the motions for modification submitted by the parties,
    it appended worksheet number 150 to its orders. Work-
    sheet number 150 states the court’s findings that the
    plaintiff’s gross weekly income was $5820 and her net
    weekly income was $3680. In its articulation, the court
    stated that it used the plaintiff’s financial affidavit, not
    her worksheet, to make its calculations, and that it did
    not include the plaintiff’s income from alimony when
    it determined her annual income.
    On the basis of our review of the exhibits in the record
    and the discrepancies between the parties’ worksheets
    regarding the plaintiff’s income and the court’s determi-
    nation, we are left with the firm conviction that a mis-
    take has been made. There is no legally proper
    evidentiary basis before the court to support its determi-
    nation of the plaintiff’s gross or net weekly income at
    the time it considered the motions for modification. In
    addition to using the incorrect documents to calculate
    the plaintiff’s income, the plaintiff contends that the
    court improperly included alimony in its calculations.
    The plaintiff included the alimony she received on her
    financial affidavit, and therefore, because the court
    used the plaintiff’s financial affidavit, it necessarily
    must have included the plaintiff’s alimony when it per-
    formed its calculations. We agree with the plaintiff that,
    pursuant to our child support statutes and regulations,
    the court may not include income from alimony when
    it calculates the income of an alimony recipient for
    purposes of determining child support.
    ‘‘Our review of the court’s interpretation of . . .
    § 46b-215a-1 (11) . . . of the Regulations of Connecti-
    cut State Agencies is plenary. . . . Section 46b-215a-1
    (11) of the Regulations of Connecticut State Agencies
    defines gross income as the average weekly earned and
    unearned income from all sources before deductions
    . . . . That section includes a nonexhaustive list of
    twenty-two inclusions. In that list of inclusions is: ali-
    mony being paid by an individual who is not a party
    to the support determination. . . . Regs., Conn. State
    Agencies § 46b-215a-1 (11) (A) (xix). The specific word-
    ing of this inclusion makes clear that only alimony
    received from a nonparty to the support determination
    is included in gross income.’’ (Citation omitted; empha-
    sis omitted; internal quotation marks omitted.) Rob-

    (2017); see also General Statutes § 46b-84.13
    The defendant agrees that the court’s finding of the
    plaintiff’s weekly income is erroneous, but he argues
    that the error is harmless and had a de minimis impact
    on the court’s order that the plaintiff pay him $137
    per week in child support. The defendant, however,
    provides no legal support for his de minimis argument,
    and we are aware of none.
    The defendant’s argument is predicated on his calcu-
    lation of the presumptive minimum child support pursu-
    ant to the child support guidelines. ‘‘[W]hen a family’s
    combined net weekly income exceeds $4000, the court
    should treat the percentage set forth in the schedule
    at the highest income level as the presumptive ceiling
    on the child support obligation, subject to rebuttal by
    application of the deviation criteria enumerated in the
    guidelines, as well as the statutory factors described in
    [General Statutes] § 46b-84 (d).’’ Maturo v. Maturo, 
    296 Conn. 80
    , 106, 
    995 A.2d 1
    (2010). ‘‘The guidelines provide
    in relevant part that, [w]hen the parents’ combined net
    weekly income exceeds [$4000], child support awards
    shall be determined on a case-by-case basis, and the
    current support prescribed at the [$4000] net weekly
    income level shall be the minimum presumptive
    amount.’’ (Internal quotation marks omitted.) 
    Id., 91. The
    guidelines establish a child support award as ‘‘the
    entire payment obligation of the noncustodial parent,
    as determined under the . . . guidelines . . . .’’
    (Emphasis omitted; internal quotation marks omitted.)
    
    Id., 117. On
    the basis of his weekly income alone, the defen-
    dant argues that the parties’ combined weekly income
    exceeds $4000, and therefore the child support for their
    son should not exceed the presumptive maximum of
    12.04 percent of that income. Given the disparity in the
    plaintiff’s annual income reported on the defendant’s
    worksheet and the court’s worksheets, the defendant
    calculates that the range of the parties’ combined
    weekly income is between $10,815.38 and $11,261.63,
    which results in a presumptive maximum child support
    award of between $1302.17 and $1355.90 per week.
    Although we may agree that there is a permissible
    range between the presumptive minimum and maxi-
    mum child support when the parties’ combined income
    exceeds $4000 per week; see Dowling v. Szymczak, 
    309 Conn. 390
    , 402, 
    72 A.3d 1
    (2013) (‘‘as long as the child
    support award is derived from a total support obligation
    within this range—between the presumptive minimum
    dollar amount and the presumptive maximum percent-
    age of net income—a finding in support of a deviation is
    not necessary’’); there is no corresponding permissible
    range of child support owed by the noncustodial parent.
    A noncustodial parent’s child support obligation is to
    be based on his or her proportionate share of the parties’
    combined net income. 
    Id., 404. In
    the present case, the trial court had two sets of
    worksheets filed by the parties and two sets of financial
    affidavits. The plaintiff’s stated income is different on
    each page and consequently each figure constitutes a
    different percentage of the parties’ combined net
    weekly income, which affects the amount of the plain-
    tiff’s child support obligation regardless of the presump-
    tive amount. Moreover, the trial court calculated the
    plaintiff’s child support share on the basis of her income
    that included alimony, which is not permitted by our
    child support statutes or regulations. Although, as the
    defendant argues, the difference between the child sup-
    port the court ordered the plaintiff to pay and what an
    accurate determination of her weekly income requires
    her to pay may not be great, the evidentiary basis of
    the court’s order is unclear. See Ferraro v. 
    Ferraro, supra
    , 
    168 Conn. App. 731
    (figures on worksheets and
    affidavits did not match, court must provide basis for
    support determinations it makes). Moreover, the error
    is harmful. The plaintiff’s presumptive share of support
    may have been less than $137 if the court had not
    included alimony in its calculation of the parties’ com-
    bined weekly income.
    The court’s finding with respect to the plaintiff’s
    income is clearly erroneous and for that reason, the
    court improperly granted the defendant’s motion to
    modify child support with respect to the child support
    it ordered the plaintiff to pay. We, therefore, reverse
    the judgment in part and remand the case for a new
    hearing with regard to the parties’ respective child sup-
    port obligations.
    B
    The plaintiff’s second claim regarding the court’s
    child support order is that the court abused its discre-
    tion by terminating the defendant’s child support obliga-
    tion retroactively because (1) the court lacked sufficient
    information to calculate the parties’ financial circum-
    stances as of September 2, 2015, and (2) she continued
    to pay for some of the expenses of the parties’ son
    from September 2, 2105, until the time of the hearing.
    We disagree.
    ‘‘Where the legal conclusions of the trial court are
    challenged, on appeal those conclusions are subject
    only to the test of abuse of discretion. . . . Discretion
    means a legal discretion, to be exercised in conformity
    with the spirit of the law and in a manner to subserve
    and not to impede or defeat the ends of substantial
    justice. . . . The salient inquiry is whether the court
    could have reasonably concluded as it did. . . . In
    determining whether the trial court has abused its dis-
    cretion, we must make every reasonable presumption
    in favor of the correctness of its action.’’ (Internal quota-

    The following facts are relevant to the plaintiff’s
    claim. The defendant previously had filed a motion for
    modification of unallocated child support and custody
    on June 3, 2014, due to the fact that he had assumed
    physical custody of the parties’ daughter. In that motion,
    the defendant did not request modification retroactive
    to the date the motion was served on the plaintiff. 
    Id., 782. The
    parties’ agreement that their daughter live with
    the defendant was accepted by the court, Hon. Stanley
    Novack, judge trial referee, in December, 2014, and the
    matter was continued several times thereafter. 
    Id. The defendant
    did not request retroactive modification until
    February 25, 2015. 
    Id. The issue
    of child support for the parties’ daughter
    was not addressed until May 7, 2015, when Judge Tindill
    held a hearing on the defendant’s motion for modifica-
    tion of unallocated alimony and child support. 
    Id., 773. The
    court issued a memorandum of decision regarding
    child support on July 31, 2015.14 
    Id. Almost immediately
    thereafter, the parties’ son took up residence in the
    defendant’s home, and the defendant filed the present
    motion for modification of custody and child support
    on August 14, 2015. The motion was served on the
    plaintiff on September 10, 2015. On the first day of the
    hearing on the present motions, the court stated that
    it was taking judicial notice of its July 31, 2015 order
    and its order accepting the parties’ stipulation that the
    defendant assumed physical custody of the parties’ son.
    1
    On appeal, the plaintiff argues that the court lacked
    sufficient information to calculate the parties’ financial
    situation on September 2, 2015, and relies on the proce-
    dural history and dicta in this court’s decision with
    respect to the defendant’s appeal. In that appeal, this
    court stated that the trial court ‘‘did not have the infor-
    mation necessary to make its child support orders retro-
    active . . . because the parties did not submit financial
    affidavits at or close to that date [of service].’’ LeSueur
    v. LeSueur, 
    172 Conn. App. 782
    . This court continued
    quoting from Judge Tindill’s July 31, 2015 memorandum
    of decision that the defendant had not submitted ‘‘a
    signed, sworn financial affidavit until ordered to do so
    by the court on May 22, 2015. Prior to June 8, 2015, the
    most recent financial affidavits filed were those filed
    on January 27, 2011.’’ (Internal quotation marks omit-
    ted.) 
    Id., 783. We
    infer from the trial court’s July 31,
    2015 memorandum of decision that it had current infor-
    mation regarding the parties’ financial circumstances
    as of June 8, 2015, which is approximately three months
    prior to September 2, 2015.
    The defendant argues, in part, that the court had
    sufficient evidence by which it could make its child
    support orders retroactive. Namely, that on September
    10, 2015, the date the plaintiff was served with the
    motion for modification, the defendant was the son’s
    custodial parent pursuant to the parties’ agreement. He
    continued to pay child support to the plaintiff notwith-
    standing that he was their son’s custodial parent and
    he had costs attributable to the son. The plaintiff con-
    tributed no financial support to the defendant for their
    son’s care. Significantly, the court had issued orders
    relative to the parties’ daughter on July 31, 2015, pursu-
    ant to the financial data available to the court at that
    time. Moreover, although the defendant had assumed
    custody of the son in early August, 2015, the court
    ordered the plaintiff to pay the defendant child support
    from November 1, 2016, until the son completed high
    school in May, 2017.
    The record supports the defendant’s argument. The
    motion to modify unallocated alimony and child support
    was served on the plaintiff on September 10, 2015, the
    defendant had assumed primary physical custody of
    the son in August, 2015, and the son was living full-
    time in the defendant’s home while the defendant con-
    tinued to pay the plaintiff pursuant to the July 31, 2015
    child support order. We conclude on the basis of the
    court’s memorandum of decision that it had information
    pertaining to the parties’ financial circumstances in
    June, 2015, which was at or near the time when the
    defendant served the motion for modification of unallo-
    cated alimony and child support on the plaintiff. There
    is no evidence in the record indicating that the plaintiff’s
    financial circumstances had changed during the sum-
    mer and fall of 2015, except that she no longer had
    custody of the parties’ son. The record discloses, and
    the plaintiff admitted during the hearing on the present
    motions, that her full-time employment did not change
    and her salary was not reduced until she filed the motion
    for modification of unallocated alimony and child sup-
    port in February, 2016.
    2
    The plaintiff also claims that the court improperly
    modified the child support order retroactive to Septem-
    ber 2, 2015, because she continued to pay expenses of
    the parties’ son from September 2, 2015, to the date of
    the hearing even though the son was not primarily living
    in her home. She claims that if the court granted the
    defendant’s motion to modify retroactively, the retroac-
    tivity should only be to February 8, 2016, which is when
    the court accepted the parties’ agreement that their son
    live with the defendant, and the date on which the
    defendant first requested that the motion be granted ret-
    roactively.
    In her brief on appeal, the plaintiff argues that she
    testified as to the expenses she incurred for the son.
    Although the court made no findings with respect to
    the expenses the plaintiff claims that she paid; see Wyatt
    Energy, Inc. v. Motiva Enterprises, LLC, 
    308 Conn. 719
    , 739–40, 
    66 A.3d 848
    (2013) (recitation of testimony
    without more does not constitute finding); the court
    found that the plaintiff’s expenses with respect to her
    children had declined. The court also found that the
    son was living full time with the defendant ‘‘as of the
    date of the instant motion.’’ It is undisputed that the
    son moved to the defendant’s home in August, 2015.
    General Statutes § 46b-224 specifically ‘‘addresses
    the question of how a change in custody affects the
    payment of child support . . . .’’ Tomlinson v. Tomlin-
    son, 
    305 Conn. 539
    , 549, 
    46 A.3d 112
    (2012). ‘‘Child
    support . . . furnishes the custodian with the
    resources to maintain a household to provide for the
    care and welfare of the children; in essence, the custo-
    dian holds the payments for the benefits of the child.
    Consequently, once custody changes, there is no imme-
    diately apparent reason for the former custodian to
    continue to receive the payments because the presump-
    tion is that the former custodian is no longer primarily
    responsible for providing the children’s necessary liv-
    ing expenses, including food, shelter and clothing. In
    turn, permitting the diversion of funds away from the
    parent providing for the care and well-being of minor
    children when custody changes, pursuant to the par-
    ents’ contractual agreement, would contravene the pur-
    pose of child support.’’ (Emphasis added.) 
    Id., 555. ‘‘Modification,
    including retroactive modification, of
    a child support order upon a change of custody under
    § 46b-224, comports with the default rule that child
    support follows the children, unless the trial court has
    made a finding that another arrangement is appropriate.
    This statute indicates that the legislature viewed the
    provision of custody as the premise underlying the
    receipt of child support payments; the legislature did
    not envision that the custodian would be required to pay
    child support to a person who does not have custody, as
    well as (in cases in which the obligor obtains custody)
    expend resources to provide directly for the care and
    welfare of the child. In fact, under the Child Support
    and Arrearage Guidelines . . . child support award is
    defined as the entire payment obligation of the noncus-
    todial parent. . . . Once custody is transferred, how-
    ever, there is no longer any basis for the presumption
    that the former custodian is spending his or her share
    of the support on the children.’’ (Citations omitted;
    emphasis in original; internal quotation marks omitted.)
    Coury v. Coury, 
    161 Conn. App. 271
    , 299, 
    128 A.3d 517
    (2015).
    In Tomlinson,15 our Supreme Court stated that ‘‘if
    the obligor becomes the new primary custodial parent,
    the obligor is no longer required to pay child support
    to the former custodian. . . . The immediate result
    . . . is . . . the originally designated payee who no
    longer has custody of the child does not continue to
    receive support payments following the change in cus-
    tody, and the payments are retained by . . . the party
    who does have custody.’’ Tomlinson v. 
    Tomlinson, supra
    , 
    305 Conn. 549
    –50.
    In the defendant’s appeal, this court stated on the
    basis of the plaintiff’s testimony that she had rebutted
    the presumption that ‘‘the former custodian is no longer
    primarily responsible for providing the children’s neces-
    sary living expenses’’ because she continued to have
    expenses associated with the care of the parties’ daugh-
    ter. (Internal quotation marks omitted.) LeSueur v. LeS-
    
    ueur, supra
    , 
    172 Conn. App. 779
    . We have reviewed the
    transcript of the hearing with respect to the parties’
    son and agree that the plaintiff testified that she paid
    certain of the son’s expenses.16 The court, however,
    made no finding that the expenses were necessary
    expenses. With regard to those expenses, her payments
    were voluntary and not for necessary expenses contem-
    plated by the child support scheme.
    In the present appeal, the plaintiff presented no evi-
    dence, and our review disclosed none, that the defen-
    dant, who was the primary custodial parent, was not
    providing for their son’s necessary expenses for food,
    shelter, and clothing. Although the plaintiff testified
    that she incurred expenses on behalf of the son, some of
    them were typical of those incurred by any noncustodial
    parent during visitation. The plaintiff presented no evi-
    dence that she was not able to pay for those expenses
    with her salary or income from investments or unallo-
    cated alimony and child support she was receiving. She
    also presented no evidence that she incurred expenses
    for the parties’ son because the defendant failed to
    meet the son’s necessary needs. The record contains
    evidence that many of the expenses the plaintiff
    incurred were the result of her voluntary decision to
    provide the son with the unlimited use of a credit card.
    The plaintiff voluntarily incurred those expenses, and
    they are not the necessary expenses contemplated by
    our case law and statutes.17
    The court found that the parties had agreed that their
    son could move to the defendant’s home soon after
    the court issued its July 31, 2015 child support orders
    regarding their daughter. It also found that the son had
    been living with the defendant since the time the motion
    to modify custody and child support was filed and that
    the defendant continued to pay the plaintiff child sup-
    port pursuant to the court’s July 31, 2015 orders. There
    is no explanation in the record as to why the motion
    to modify, filed in August, 2015, was not heard until
    February 8, 2016, which is when the court accepted the
    parties’ agreement that the defendant would assume
    custody of their son.
    On the basis of our review of the record, the court’s
    orders, and the briefs of the parties, we conclude that
    the court did not abuse its discretion by granting the
    defendant’s motion for modification and terminating
    the defendant’s child support obligation to pay the plain-
    tiff retroactively, as the plaintiff failed to demonstrate
    that she required child support in order to provide for
    the son’s necessary expenses. However, in her reply
    brief, the plaintiff noted that the court terminated the
    defendant’s child support obligation as of September
    2, 2015, which predates the time his motion to modify
    custody and child support was served on the plaintiff
    on September 10, 2015. On remand, the court is ordered
    to set the retroactive date to a time subsequent to Sep-
    tember 10, 2015.
    II
    The plaintiff’s second claim is that the court miscon-
    strued the separation agreement and consequently
    ordered the parties to timely pay the postsecondary
    tuition expenses of their children. We disagree that the
    court misconstrued the separation agreement.
    During the hearing on their motions for modification,
    the parties asked the court to determine their respective
    obligations, if any, to pay the college tuitions of their
    children. Article 13 of the separation agreement, titled
    Miscellaneous Child Support Matters, is at the center
    of the plaintiff’s claim. Paragraph 13 (B) (iv) of the
    separation agreement concerns the children’s postsec-
    ondary education and provides as follows: ‘‘In the event
    that a child, upon graduating high school, attends a
    fully accredited college or university and matriculates
    in a course of study leading to an undergraduate degree,
    the parties shall each contribute their proportionate
    share to the cost thereof, in accordance with their
    income at that time (including any [pretax income from
    employment] being paid by [the defendant] to [the plain-
    tiff]), after the child has made application for all avail-
    able financial aid, grants and scholarships. The
    [defendant] and [the plaintiff] shall consult with each
    other and with the child concerned with respect to the
    education of any or all of the children and with respect
    to the selection of schools or colleges which they shall
    attend. The selection of said schools and/or colleges
    shall be by mutual agreement. In the event that the
    parties are unable to agree on a school and/or their
    respective obligations therefore, it is understood and
    agreed that the Court shall retain jurisdiction pursuant
    to the . . . General Statutes to determine the amount
    of each [party’s] required contribution, up to the cost
    of in state tuition at a school which is part of the Con-
    necticut state university system and either party may
    submit the dispute to a court of competent jurisdiction
    for determination thereof. The parties’ obligations pur-
    suant to this [Article 13 (B) (iv)] shall continue with
    respect to each child despite a child having attained
    the age of majority, but in no event beyond a child’s
    twenty-third . . . birthday.’’
    During the hearing, the defendant testified that para-
    graph 13 (B) (iv) of the separation agreement meant
    that there was no limit, or so-called UConn cap, on their
    respective tuition contributions if the parties agreed on
    the respective school or college their children would
    attend. The plaintiff testified that she believed that the
    UConn cap applied if the parties could not agree on
    their respective financial obligations. The court found
    that the parties mutually agreed that their daughter
    would attend Princeton University and their son Dart-
    mouth College and that neither the UConn cap nor the
    cost of a four year degree within the Connecticut state
    university system applied as contended by the plaintiff.
    On appeal, the plaintiff claims that the court improp-
    erly ordered the parties to pay their children’s tuition
    at their respective colleges because the court did not
    find that the parties had agreed to exceed the limit
    imposed by General Statutes § 46b-56c (f).18 The plain-
    tiff, therefore, asserts that the court erred in finding
    that the UConn cap and the cost of instate tuition at a
    school that is part of the Connecticut state university
    system do not apply and improperly ordered the parties
    to pay timely educational support to Princeton Univer-
    sity and Dartmouth College as required by paragraphs
    7 (F) and 13 (B) (iv) of the separation agreement.
    ‘‘It is well established that a separation agreement,
    incorporated by reference into a judgment of dissolu-
    tion, is to be regarded and construed as a contract.
    . . . Accordingly, our review of a trial court’s interpre-
    tation of a separation agreement is guided by the general
    principles governing the construction of contracts. . . .
    A contract must be construed to effectuate the intent
    of the parties, which is determined from the language
    used interpreted in the light of the situation of the
    parties and the circumstances connected with the trans-
    action. . . . If a contract is unambiguous within its four
    corners, the determination of what the parties intended
    by their contractual commitments is a question of law.
    . . . When the language of a contract is ambiguous,
    [however] the determination of the parties’ intent is a
    question of fact, and the trial court’s interpretation is
    subject to reversal on appeal only if it is clearly errone-
    ous.’’ (Citations omitted; internal quotation marks omit-
    ted.) Remillard v. Remillard, 
    297 Conn. 345
    , 354–55,
    
    999 A.2d 713
    (2010).
    On the basis of our review of Article 13 (B) (iv) of
    the agreement, we conclude that the language is clear
    and unambiguous. The first clause of the subject article
    addresses the circumstances under which the parties
    will pay postsecondary tuition for their children. The
    child must have been graduated from high school,
    desires to attend a fully accredited college or school,
    and matriculated in a course of study leading to an
    undergraduate degree. The next clause states that each
    party shall pay his or her proportionate share in accor-
    dance with his or her income at the time after the child
    has applied for financial assistance. The next sentence
    addresses the manner in which the decision as to the
    postsecondary educational institution the child is to
    attend is to be made, i.e., the parties shall consult with
    each other and with the child concerned with respect
    to the education of any or all of the children and with
    respect to the selection of schools or colleges which
    they shall attend. The selection of said schools and/or
    colleges shall be by mutual agreement.
    In the present case, there is no dispute that the parties
    and their children mutually agreed that their daughter
    would attend Princeton University and their son would
    attend Dartmouth College. Because the parties mutu-
    ally agreed, it is unnecessary to consider the next sen-
    tence of the article, which only applies when the parties
    are unable to agree on the educational institution and/
    or their respective obligations therefore. The word
    therefore refers back to the educational institution
    about which there is no agreement. Consequently, the
    court properly determined that the UConn cap and
    tuition limit on a four year degree from a Connecticut
    state university system did not apply under the present
    circumstances where the parties and their children
    mutually agreed that their daughter should attend
    Princeton University and their son should attend Dart-
    mouth College.
    Moreover, we will not construe an agreement to reach
    a patently absurd result. The separation agreement
    clearly is intended to have the parties and their children
    mutually contemplate, investigate, and agree on the
    appropriate postsecondary educational institutions the
    children shall attend. Common sense dictates that
    tuition and related costs would be taken into consider-
    ation during that process. The plaintiff’s construction
    of the agreement that after the family mutually agrees
    on the appropriate educational institutions for their
    children the parties will not pay the cost of tuition that
    exceeds that of the UConn cap would undermine the
    very purpose of the agreement. We can only imagine
    how family harmony would be disrupted and the disap-
    pointment, frustration, and perhaps anger, the child
    may feel after the family agrees to the postsecondary
    educational institution the child would attend but that
    she or he alone must bear any tuition burden that
    exceeds the UConn cap.19 We decline to sanction the
    plaintiff’s construction of the unambiguous language of
    the separation agreement. We, therefore, conclude that
    the court properly determined that the provision of the
    separation agreement regarding the UConn cap and the
    tuition limit of a four year college degree from the
    Connecticut state university system do not apply
    because the parties and their children mutually agreed
    on the postsecondary institutions the children would
    attend, i.e., Princeton University and Dartmouth
    College.
    III
    The plaintiff’s final claim is that the court improperly
    denied her motion to modify unallocated alimony and
    child support. We do not agree.
    The following facts are pertinent to this claim. On
    February 10, 2016, the plaintiff filed a motion for modifi-
    cation of unallocated alimony and support, postjudg-
    ment, asking the court to increase the amount of
    unallocated alimony and support she received from the
    defendant on the basis of his pretax income from
    employment. In the motion, the plaintiff quoted that
    portion of the agreement regarding the amount of ali-
    mony and support she was to receive from the defen-
    dant as of August 1, 2015. She also quoted paragraph
    12.8 (c) of the agreement, which states in relevant part:
    ‘‘In no event shall the percentage formulae set forth in
    paragraph 12.1 (a), (b) and (c) of this Agreement or in
    any decree incorporating its provisions . . . be
    changed or amended by the parties or the court; except
    that either party shall be entitled to seek modification
    of the percentage formulae . . . in the event of a sub-
    stantial change of circumstances of either party . . .
    or ordered by a [c]ourt that one or more of the children
    shall reside with the [defendant] as his or her primary
    residence. At the time that this agreement was executed
    the [plaintiff] had a salary . . . of $125,000 per year
    and for the preceding year her income was $75,000 per
    year. At the time that this agreement was executed,
    the [defendant] had [pretax income from employment]
    totaling $647,000 and for 2009 he had [pretax income
    from employment] for 2010 totaling $477,459.’’ The
    plaintiff argued that since the dissolution judgment was
    rendered, her financial circumstances had changed sub-
    stantially in that her salary had decreased from $125,000
    per year to $95,000. She asked the court to increase the
    defendant’s alimony obligation retroactive to the date
    the motion was served on the defendant.
    Following a hearing on the motion, the court found
    that the plaintiff alleged several substantial changes in
    circumstances since January 27, 2011, namely that her
    earnings from employment had decreased significantly,
    the defendant no longer paid child support for the par-
    ties’ daughter, the amount of alimony she received from
    the defendant had decreased on August 1, 2015, pursu-
    ant to the dissolution agreement, and the defendant
    had filed a motion to terminate child support for the
    parties’ son.
    In issuing its order, the court stated that it had
    reviewed the motions of the parties and considered
    their testimony and all the evidence they had submitted.
    In addition, the court stated that it had considered the
    relevant rules, case law and statutory provisions, as
    well as the arguments of counsel.20 The court found that
    the plaintiff has been employed by Shumway Capital,
    a private family foundation, for the past five years. At
    the time of dissolution, she was employed full-time at
    an annual salary of $125,000. The court found that at
    approximately the time she filed the motion to modify
    unallocated alimony and child support on February 10,
    2016, the plaintiff became a part-time employee earning
    a salary of approximately $95,000 and that the decrease
    in the plaintiff’s salary constituted a substantial change
    in circumstances. The court also found that the plain-
    tiff’s monthly expenses for shelter, transportation, the
    children and her liabilities had decreased since January
    27, 2011.
    In addition, the court found that following the change
    of custody with respect to the parties’ daughter, the
    defendant has paid support to the plaintiff in accor-
    dance with the agreement and the court’s orders. It also
    found that the agreement’s original percentage formu-
    lae using the defendant’s pretax income from employ-
    ment to calculate and determine the plaintiff’s
    unallocated support continues to be sufficient to fulfill
    its intended purpose to equalize the income of the par-
    ties and support the children. The court, therefore,
    denied the plaintiff’s motion to modify the percentage
    formulae of paragraph 12 of the agreement.
    On appeal, the plaintiff claims that the court abused
    its discretion by denying her motion to increase her
    unallocated alimony and support. She argues that
    because the court determined that the reduction in her
    salary constituted a substantial change in circum-
    stances; see General Statutes § 46b-86;21 the court was
    obligated to consider all of the factors in General Stat-
    utes § 46b-8222 to order alimony in accordance with the
    needs and financial resources of the parties, and she
    cites Schwarz v. Schwarz, 
    124 Conn. App. 472
    , 478, 
    5 A.3d 548
    (once court determines a substantial change
    in circumstances exists, it must consider all factors in
    § 46b-82 to order alimony in accord with needs and
    financial resources of each party), cert. denied, 
    299 Conn. 909
    , 
    10 A.3d 525
    (2010). In making this argument,
    the plaintiff fails to consider that the court stated that
    in ruling on the motion to modify unallocated alimony
    and child support, it had considered the relevant stat-
    utes and case law. A court need not ‘‘make explicit
    reference to the statutory criteria that it considered in
    making its decision or make express findings as to each
    statutory factor.’’ Caffe v. Caffe, 
    240 Conn. 79
    , 82–83,
    
    689 A.2d 468
    (1997); see also Brown v. Brown, 
    148 Conn. App. 13
    , 22, 
    84 A.3d 905
    (court expressly stated
    it had considered all relevant statutes before rendering
    judgment), cert. denied, 311 Con. 933, 
    88 A.3d 549
    (2014).
    Moreover, ‘‘[a] fundamental principle in dissolution
    actions is that a trial court may exercise broad discre-
    tion in awarding alimony and dividing property as long
    as it considers all relevant statutory criteria. . . . No
    single criterion is preferred over others, and the trial
    court has broad discretion in varying the weight placed
    on each criterion under the circumstances of each
    case.’’ (Internal quotation marks omitted.) Brown v.

    ,

    . ‘‘Once a trial court
    determines that there has been a substantial change in
    the financial circumstances of one of the parties, the
    same criteria that determine an initial award of alimony
    . . . are relevant to the question of modification.’’

    kowski,

    Paragraph 12.8 (c) of the agreement states: ‘‘In no
    event shall the percentage formulae set forth in para-
    graph 12.1 (a), (b) and (c) of this Agreement or in any
    decree incorporating its provisions, in whole or in part,
    be changed or amended by the parties or the court;
    except that either party shall be entitled to seek a modi-
    fication of the percentage formulae set forth in para-
    graphs 12.1 (a), (b) and (c) in the event of a substantial
    change of circumstances of either party . . . .’’ By the
    agreement’s plain terms, the plaintiff was entitled to
    seek a modification of the formulae used to determine
    her unallocated alimony and child support on the basis
    of the defendant’s pretax income from employment,
    but the agreement did not require that the formulae
    be modified on the basis of the substantial change of
    circumstances.
    In the present case, the plaintiff’s employment was
    reduced from full-time to part-time and her salary was
    reduced from $125,000 to $95,000, which the court
    found to be a substantial change of circumstances. The
    court also found that there had been a significant reduc-
    tion in the plaintiff’s expenses for housing, transporta-
    tion, and her children. Both of the children were then
    in the custody of the defendant and residing with him.
    ‘‘Appellate courts look at the record, and determine
    whether the [trial] court either incorrectly applied the
    law or could not reasonably conclude as it did.’’ (Inter-
    nal quotation marks omitted.) Caffe v. 
    Caffe, supra
    ,
    
    240 Conn. 83
    . We have reviewed the transcripts of the
    hearing on the parties’ motions and the exhibits. The
    record discloses evidence that supports the court’s find-
    ing that there has been a decrease in the plaintiff’s
    expenses, most particularly with respect to housing.
    She had been living in an apartment paying $4700 a
    month in rent, but purchased a condominium that was
    in foreclosure and was then paying $2500.86 per month
    for the mortgage. She acknowledged that the interest
    payments on the mortgage and property taxes were tax
    deductible. She was able to purchase a Lexus ‘‘demo’’
    automobile and continued to make contributions to her
    401k plan. She works thirty hours a week and is partially
    covered by her employer’s health insurance. The plain-
    tiff presented no evidence that she has issues related
    to poor health or that she is unable to work. She holds
    a master of business administration degree. Moreover,
    the defendant has pointed out that the plaintiff’s finan-
    cial affidavit discloses that she has investments that
    yield significant dividends and interest.
    As to the plaintiff’s argument that the amount of
    money she received from the defendant was reduced
    due to the fact that she no longer was receiving child
    support for the parties’ daughter, child support follows
    the child. The fundamental purpose of child support is
    to provide for the care and well-being of minor children.
    Tomlinson v. 
    Tomlinson, supra
    305 Conn. 555
    . More-
    over, the agreement contemplated that the children
    might live with the defendant, which constituted a sub-
    stantial change of circumstances, warranting a change
    of unallocated alimony and child support. The court
    stated that the unallocated support the plaintiff was
    receiving continued to be sufficient to fulfill its intended
    purpose to equalize the income of the parties and sup-
    port the children. The court, therefore, denied the plain-
    tiff’s motion to modify the percentage formulae of
    paragraph 12 of the agreement.
    Both of the parties agree that the formulae used to
    calculate the amount of support the plaintiff is to
    receive from the defendant’s pretax income from
    employment were not intended to equalize their
    incomes. According to the defendant, the parties agreed
    that the plaintiff would receive a greater amount of
    alimony as the defendant’s income increased, but the
    amount of alimony as a percentage of that income
    would decline. The defendant notes that their incomes,
    even after he paid the plaintiff pursuant to the formulae,
    were never equal, even at the time of dissolution. He
    argues that ‘‘equalize’’ means that the parties’ incomes
    could be balanced. The parties did not ask the court
    to articulate what it meant that the unallocated support
    provided under paragraph 12 of the agreement equal-
    ized their incomes, and we will not speculate as to its
    meaning. That finding, however, is not relevant to our
    determination of whether the court abused its discre-
    tion by denying the plaintiff’s motion for modification
    of unallocated alimony and child support.
    When these highly educated and sophisticated parties
    signed the agreement at the time their marriage was
    dissolved, they had negotiated its provisions with the
    assistance of counsel. They bargained for a change of
    unallocated support if one or both of their children
    decided to live with the defendant, and they bargained
    for the percentage of support the plaintiff would receive
    from the defendant’s pretax income from employment
    and that the percentages stepped down over time. There
    is no evidence in the record that the plaintiff has brought
    to our attention that the amount of unallocated alimony
    and support she receives is insufficient to meet her
    needs. See Dombrowski v. Noyes-Dombrowski, 
    273 Conn. 127
    , 132, 
    869 A.2d 164
    (2005) (purpose of periodic
    alimony to provide continuing support). The court,
    therefore, did not abuse its discretion by denying the
    plaintiff’s motion to modify unallocated alimony and
    child support.
    The judgment is reversed with respect to the trial
    court’s determination regarding the plaintiff’s child sup-
    port obligation and the date on which the defendant’s
    child support obligation terminated, and the case is
    remanded for further proceedings consistent with this
    opinion; the judgment is affirmed in all other respects.
    In this opinion the other judges concurred.
    1
    The son’s move to the defendant’s home coincided with the judgment
    modifying the child support obligations of the parties with respect to the
    daughter’s residing with the defendant.
    2
    The motion to modify custody and child support was served on the
    plaintiff on September 10, 2015.
    3
    Pursuant to the agreement, the amount of unallocated alimony and child
    support the defendant has to pay to the plaintiff annually is calculated as
    a percentage of his pretax income from employment. The term of unallocated
    alimony and child support is from March 11, 2011, until June 30, 2020. The
    percentage is calculated pursuant to an agreed upon stepdown formula that
    reduces the percentage of the defendant’s pretax income payable to the
    plaintiff. The amount of the defendant’s pretax income from employment
    on which the plaintiff’s alimony is calculated is capped at $1 million annually.
    From August 1, 2015, until January 31, 2017, the unallocated alimony and
    child support the defendant was to pay the plaintiff was to be calculated
    on the basis of the following formula.
    Pretax Income Received by the              Percentage to be Paid
    defendant from Employment                  to the plaintiff
    $0 to $316,000                               40 percent
    $316,001 to $660,000                         26.5 percent
    $661,000 to $1,000,000                       19 percent
    4
    Paragraph 13 of the separation agreement, titled ‘‘Miscellaneous Child
    Support Matters,’’ provides in relevant part:
    ‘‘A. Based on the parties combined parental income the [defendant] shall
    be responsible for [50] percent of child support ‘add-ons’ and the [plaintiff]
    shall be responsible for [50] percent of the child support add-ons. [Add-ons]
    for purposes of this Agreement include the following: reasonable child care
    expenses (incurred when a party is working); mutually agreed upon educa-
    tion expenses other than those addressed in C below, including but not
    limited to tutoring; extracurricular school activities and lessons including
    sports and music; and summer camp.’’
    5
    During the portion of the hearing held on May 17, 2016, counsel for the
    parties asked the court to consider an additional matter regarding the parties’
    obligation to pay for their children’s postsecondary education. The court
    agreed to consider the matter. See part II of this opinion.
    6
    The court also denied the plaintiff’s motion to modify the allocation of
    expenses, ‘‘add-ons,’’ and private school tuition between the parties. On
    appeal, the plaintiff has not claimed that the court abused its discretion in
    that regard. (Internal quotation marks omitted.)

    The parties’ daughter was recruited to play field hockey at Princeton
    University and their son was recruited to play ice hockey at Dartmouth
    College.

    of tuition paid by a ‘‘full-time in-state student’’ to attend the University
    of Connecticut.
    9
    The plaintiff does not claim that the court improperly accepted the
    parties’ stipulation that their son would live with the defendant. Her claim
    pertains only to the court’s child support orders.
    10
    Paragraph 12.8 (c) of the agreement provides in relevant part: ‘‘In no
    event shall the percentage formulae set forth in paragraph 12.1 (a), (b) and
    (c) of this Agreement or in any decree incorporating its provisions, in whole
    or in part, be changed or amended by the parties or the court; except
    that either party shall be entitled to seek a modification of the percentage
    formulae set forth in paragraph 12.1 (a), (b) and (c) in the event of a
    substantial change of circumstances of either party or in the event it is
    agreed by the parties or ordered by a Court that one or more of the children
    shall reside with the [defendant] as his or her primary residence.’’

    The plaintiff’s May 17, 2016 financial affidavit shows the plaintiff’s gross
    weekly income to be $5339.56, which includes alimony and child support.
    The plaintiff reported $7916.66 in gross monthly salary from her employer,
    $4317.20 of child support, $7134.24 in monthly alimony, and $3770 in monthly
    dividend and interest income.
    13
    General Statutes § 46b-84 (a) provides in relevant part: ‘‘Upon or subse-
    quent to the . . . dissolution of any marriage . . . the parents of a minor
    child of the marriage, shall maintain the child according to their respective
    abilities, if the child is in need of maintenance. Any postjudgment procedure
    afforded by chapter 906 shall be available to secure the present and future
    financial interests of a party in connection with a final order for the periodic
    payment of child support.’’
    14
    The trial court ‘‘modified the defendant’s child support obligation retro-
    active to December 9, 2014, rather than the date that the motion was served
    on June 30, 2014, because it found that December 9, 2014, was the date
    when his primary physical custody of the daughter was no longer temporary.’’

    The question in Tomlinson was whether a provision in the parties’
    separation agreement that expressly prohibited modification of child support
    pursuant to the nonmodification clause of § 46b-86 (a) precluded a trial
    court from modifying the child support portion of an unallocated support
    order. Our Supreme Court noted that ‘‘while § 46b-86 (a) addresses the
    modification of child support in general, § 46b-224 covers the particular
    effect of a change in custody on preexisting child support orders.’’ Tomlinson

    With respect to the defendant’s appeal in LeSueur v. 
    LeSueur, supra
    ,
    
    172 Conn. App. 767
    , it is unclear whether the trial court made a factual
    finding as to whether the expenses paid by the plaintiff on behalf of the
    parties’ daughter when she was in the defendant’s custody were necessary
    expenses. This court concluded, however, on the basis of the plaintiff’s
    testimony in the record that the plaintiff had incurred necessary expenses
    for the daughter after she had moved to the defendant’s home. 
    Id., 778–79. In
    the present appeal, the plaintiff again testified that she incurred expenses
    for the parties’ son after he moved into the defendant’s home. The trial
    court made no finding that those expenses were necessary expenses. We
    are constrained by the factual findings of the trial court, as it is well known
    that appellate courts do not make findings of fact on the basis of the record.
    See In re Carissa K.,

    The plaintiff testified that the parties’ son used the credit card when
    he ate at restaurants with his friends, to purchase concert tickets, and to
    pay for Uber rides from the airport, among other things. The son also let
    the parties’ daughter use his credit card when she misplaced the credit card
    the plaintiff had provided to her.
    18
    General Statutes § 46b-56c (f) is not mentioned in the separation
    agreement.
    19
    Both in the trial court and at oral argument before us, the plaintiff, who
    is herself a graduate of Princeton University, had no plan for how her
    children’s tuition would be paid if not pursuant to the separation agreement.
    She expected the court to fashion a remedy. The court will not fashion a
    remedy in the face of the unambiguous plan in the parties’ separation
    agreement.

    Our review of the transcript of the hearing discloses that the court took
    judicial notice of prior proceedings in the file.
    21
    General Statutes § 46b-86 (b) provides in relevant part: ‘‘In the event
    that a final judgment incorporates a provision of an agreement in which
    the parties agree to circumstances, other than as provided in this subsection,
    under which alimony will be modified including suspension, reduction, or
    termination of alimony, the court shall enforce the provision of such
    agreement and enter orders in accordance therewith.’’
    22
    General Statutes § 46b-82 (a) provides in relevant part: ‘‘In determining
    whether alimony shall be awarded . . . the court shall consider the evi-
    dence presented by each party and shall consider the length of the marriage,
    the causes for the annulment, dissolution of the marriage or legal separation,
    the age, health, station, occupation, amount and sources of income, earning
    capacity, vocational skills, education, employability, estate and needs of
    each of the parties . . . .’’
