    KARL ANDERS HEBRAND v. ANNIKA HEBRAND
    (AC 44703)
    Moll, Suarez and Seeley, Js.
    Syllabus
    The defendant, whose marriage to the plaintiff previously had been dis-
    solved, appealed to this court from the judgment of the trial court
    denying her motion to open and vacate a prior trial court’s postjudgment
    modification of the plaintiff’s alimony obligation. In 2017, the trial court
    modified the plaintiff’s alimony obligation in accordance with a stipu-
    lated agreement the parties had filed with the court. The defendant did
    not file her motion to open until three years later, in 2020. On appeal,
    the defendant claimed, inter alia, that the court improperly concluded
    that she failed to prove that the plaintiff had fraudulently induced her
    to enter into the 2017 modification agreement and that the modification
    court lacked subject matter jurisdiction to consider the agreement
    because, inter alia, the plaintiff mislabeled the motion to modify the
    alimony obligation and failed to pay the required filing fee. Held:
    1. The defendant’s contention that the modification court lacked subject
    matter jurisdiction to consider and modify the plaintiff’s alimony obliga-
    tion was meritless; none of the purported defects in the motion to modify
    would have deprived the court of jurisdiction, and the defendant failed
    to provide any authority to support her jurisdictional claims.
    2. The trial court did not abuse its discretion in denying the defendant’s
    motion to open and vacate the modification court’s alimony order: the
    defendant failed to establish that the plaintiff fraudulently induced her
    to join his efforts to modify the alimony obligation, as the evidence
    showed that the parties negotiated the agreement with the advice of
    their counsel and that the defendant chose to sign the agreement despite
    her counsel’s advice not to do so.
    3. The defendant’s claims that the modification court improperly failed to
    find the occurrence of a substantial change in the parties’ circumstances
    and to conform its order to those changes was unavailing; because the
    plaintiff failed to file her motion to open or an appeal from the 2017
    alimony modification within the twenty day appeal period, the claims
    she raised constituted an untimely and impermissible collateral attack
    on the actions of the modification court, as she could test only whether
    the court abused its discretion in denying her motion to open and vacate
    the alimony modification.

    Procedural History
    Action for the dissolution of a marriage, and for other
    relief, brought to the Superior Court in the judicial dis-
    trict of Stamford-Norwalk and tried to the court, Hon.
    Stanley Novack, judge trial referee; judgment dissolving
    the marriage and granting certain other relief in accor-
    dance with the parties’ separation agreement; there-
    after, the court, Hon. Stanley Novack, judge trial ref-
    eree, granted the parties’ joint motion to modify alimony
    and other financial orders; subsequently, the court, M.
    Moore, J., denied the defendant’s motion to open the
    modified order of alimony and other financial orders,
    and the defendant appealed to this court. Affirmed.

    Opinion
    SEELEY, J. The defendant, Annika Hebrand, appeals
    from the judgment of the trial court denying her motion
    to open a 2017 postjudgment modification, following
    the 2013 dissolution of her marriage to the plaintiff,
    Karl Anders Hebrand. The defendant claims that (1)
    the trial court lacked subject matter jurisdiction, in
    2017, to modify the dissolution judgment, and (2) the
    court, in 2020, improperly failed to find fraud in denying
    her motion to open. Additionally, the defendant set forth
    a myriad of other claims in support of her efforts to
    reverse the denial of her motion to open. The plaintiff
    counters, inter alia, that the defendant’s jurisdictional
    claim is without merit, the court properly determined
    that the defendant failed to prove her allegations of
    fraud, and the remainder of her claims are without
    merit. We agree with the plaintiff, and, accordingly,
    affirm the judgment of the trial court denying the motion
    to open.
    The following facts and procedural history are rele-
    vant to the resolution of this appeal. The parties married
    on August 10, 1991, in Gislov, Sweden. On October 25,
    2011, the plaintiff commenced the underlying dissolu-
    tion action, alleging that the marriage had broken down
    irretrievably. On January 17, 2013, the parties entered
    into a settlement agreement to resolve the financial and
    property matters (2013 agreement).1 The 2013 agree-
    ment provided, in relevant part, that the plaintiff would
    pay alimony to the defendant until her death or remar-
    riage, or until he attained the age of sixty-five. The
    plaintiff agreed to pay the defendant a monthly amount
    equal to 27.5 percent of the first $625,000 of his gross
    earned annual income from employment and an addi-
    tional 10 percent of his gross earned annual income
    between $625,000 and $750,000. The 2013 agreement
    provided that ‘‘[i]n the event that the [plaintiff’s] com-
    pensation changes substantially . . . the [defendant]
    shall have the right to petition the court for such modifi-
    cation as she believes appropriate.’’ The 2013 agreement
    also provided for child support to the defendant for the
    parties’ three minor children. The court, Hon. Stanley
    Novack, judge trial referee, dissolved the parties’ mar-
    riage and incorporated the 2013 agreement into the
    judgment of dissolution.
    On November 15, 2017, the parties jointly moved to
    modify certain financial aspects of the 2013 agreement.
    On December 20, 2017, the parties filed a stipulation
    with the court (2017 modification). The 2017 modifica-
    tion provided that the plaintiff would pay the defendant
    monthly alimony at a fixed amount of $7000.2 The par-
    ties expressly stated that they had the opportunity to
    obtain independent legal counsel and that each had
    been advised by an attorney with respect to the 2017
    modification.
    Judge Novack held a hearing on December 20, 2017,
    where the parties appeared as self-represented liti-
    gants.3 In response to a question from the court, the
    defendant stated that she had consulted with an attor-
    ney and indicated that the $7000 per month in alimony
    was fair. She further stated that she voluntarily agreed
    to the change in alimony and that she had not been
    forced into it by anyone. The court then granted the
    parties’ motion and issued a new order of alimony in
    accordance with the parties’ stipulation.
    On June 29, 2020, the plaintiff moved to modify the
    judgment.4 In his motion to modify, he argued that,
    subsequent to the 2017 modification, a substantial
    change in circumstances had occurred.5 The plaintiff
    represented that his income decreased, his expenses
    increased, the defendant’s expenses decreased, and that
    ‘‘[t]he defendant has been living together with another
    person under circumstances which should result in the
    modification, suspension, reduction or termination of
    alimony because the living arrangements have caused
    such a change of circumstances as to alter the financial
    needs for the defendant.’’ The plaintiff sought, inter alia,
    to reduce or terminate his alimony obligation.
    Thereafter, on October 9, 2020, the defendant filed a
    motion to open the 2017 modification. On February 25,
    2021, she filed a second amended motion to open and
    vacate the 2017 modification. Therein, she set forth
    fifteen bases for vacating the 2017 modification, includ-
    ing lack of jurisdiction, lack of statutory authority, fraud
    in the inducement, and mistake. On April 9, 2021, the
    court, M. Moore, J., held a hearing on the defendant’s
    motion.
    The court issued its order on April 30, 2021. It stated:
    ‘‘The crux of the defendant’s argument is that she and
    the plaintiff discussed modifying the alimony to a
    reduced figure which would be nonmodifiable in the
    event she cohabitated or remarried. The stipulation
    signed by both parties and approved in 2017 has no
    such provision regarding nonmodifiable alimony. The
    defendant now claims that the plaintiff committed fraud
    in the inducement and misrepresentation of material
    facts.’’ The court concluded that the defendant had
    failed to prove, by clear and convincing evidence, that
    the plaintiff had made a false representation.
    Addressing the remainder of the defendant’s argu-
    ments, the court explained: ‘‘The defendant presented
    several additional bases for reopening and vacating the
    [2017 modification]: the [modification] was prohibited
    by the separation agreement, the motion was not prop-
    erly filed because no fee was paid, motion was not
    properly titled, lack of jurisdiction, lack of authority,
    proper authority not cited in motion, lack of finding of
    substantial change in circumstances, negligent misrep-
    resentation, lack of jurisdiction for retroactive modifi-
    cation of alimony by agreement, mistake, accident,
    estoppel by nonmodifiable clause, and lack of subject
    matter jurisdiction. The defendant failed to provide any
    credible evidence or case law to substantiate the addi-
    tional claims made in her motion. The motion to open
    and vacate is denied.’’ (Emphasis added.) This appeal
    followed.
    We begin with the applicable standard of review. ‘‘Our
    review of a court’s denial of a motion to open [based
    on fraud] is well settled. We do not undertake a plenary
    review of the merits of a decision of the trial court . . .
    to deny a motion to open a judgment. . . . In an appeal
    from a denial of a motion to open a judgment, our
    review is limited to the issue of whether the trial court
    has acted unreasonably and in clear abuse of its discre-
    tion. . . . In determining whether the trial court
    abused its discretion, this court must make every rea-
    sonable presumption in favor of its action. . . . The
    manner in which [this] discretion is exercised will not
    be disturbed so long as the court could reasonably
    conclude as it did.’’ (Internal quotation marks omitted.)

    , 204, 
    272 A.3d 1121
    (2022). In applying this standard, the court’s factual
    findings will not be disturbed unless they are clearly
    erroneous. See, e.g., Lavy v. Lavy, 
    190 Conn. App. 186
    ,

     (2019).
    I
    The defendant first claims that the court lacked sub-
    ject matter jurisdiction to modify the dissolution judg-
    ment in 2017. Specifically, she argues that the plaintiff
    labeled his filing as a motion for order, rather than a
    motion to modify, and failed to pay the required filing
    fee. The defendant contends that, as a result of these
    purported defects, the court lacked subject matter juris-
    diction to modify the 2013 dissolution judgment. We
    conclude that the trial court had subject matter jurisdic-
    tion to consider and accept the parties’ 2017 modifica-
    tion and that the defects alleged by the defendant, even
    if accepted as true, would not deprive the court of
    subject matter jurisdiction.6 Accordingly, this claim
    must fail.7
    It is axiomatic that ‘‘[s]ubject matter jurisdiction
    involves the authority of the court to adjudicate the
    type of controversy presented by the action before it.
    . . . [A] court lacks discretion to consider the merits
    of a case over which it is without jurisdiction . . . .
    The subject matter jurisdiction requirement may not be
    waived by any party, and also may be raised by a party,
    or by the court sua sponte, at any stage of the proceed-
    ings, including on appeal.’’ (Internal quotation marks
    omitted.) Sousa v. Sousa, 
    322 Conn. 757
    , 770, 
    143 A.3d 578
     (2016). Although we review the decision of the trial
    court to grant or deny a motion to open under the abuse
    of discretion standard, an underlying issue of subject
    matter jurisdiction presents a question of law subject
    to plenary review by this court. Tittle v. Skipp-Tittle,
    
    161 Conn. App. 542
    , 549, 
    128 A.3d 590
     (2015).
    Our Supreme Court expressly has stated that ‘‘the
    Superior Court is a general jurisdiction tribunal with
    plenary and general subject matter jurisdiction over
    legal disputes in family relations matters under General
    Statutes § 46b-1 . . . .’’8 (Citation omitted; footnote
    omitted; internal quotation marks omitted.) Sousa v.
    Sousa, supra, 
    322 Conn. 776
    –77. Section 46b-1 provides
    in relevant part that ‘‘[m]atters within the jurisdiction
    of the Superior Court deemed to be family relations
    matters shall be matters affecting or involving . . . (4)
    alimony, support, custody and change of name incident
    to dissolution of marriage, legal separation and annul-
    ment . . . .’’ It is clear, therefore, that the Superior
    Court had jurisdiction to consider and grant the postdis-
    solution motion to modify the award of alimony in this
    case. See Tittle v. Skipp-Tittle, supra, 
    161 Conn. App. 549
     (§ 46b-1 (4) provides that Superior Court has juris-
    diction over disputes in family relations matters, and
    General Statutes § 46b-86 (a) provides that court has
    continuing subject matter jurisdiction to modify ali-
    mony).
    Furthermore, none of the defects alleged by the
    defendant, even if true, would have deprived the court
    of subject matter jurisdiction with respect to the 2017
    modification. Specifically, the arguments that the plain-
    tiff mislabeled his 2017 motion and failed to pay a
    required filing fee simply are not jurisdictional in nature.
    Regarding the former, our case law has recognized that
    ‘‘a motion is to be decided on the basis of the substance
    of the relief sought rather than on the form or the label
    affixed to the motion. . . . It is the substance of a
    motion, therefore, that governs its outcome, rather than
    how it is characterized in the title given to it by the
    movant.’’ (Citations omitted.) State v. Taylor, 
    91 Conn. App. 788
    , 791–92, 
    882 A.2d 682
    , cert. denied, 
    276 Conn. 928
    , 
    889 A.2d 819
     (2005); see also Silver v. Silver, 
    200 Conn. App. 505
    , 520, 
    238 A.3d 823
    , cert. denied, 
    335 Conn. 973
    , 
    240 A.3d 1055
     (2020). In regard to the latter,
    this court has noted that the failure to pay a filing fee
    is not jurisdictional in nature. See Bruno v. Bruno, 
    146 Conn. App. 214
    , 228–29 n.13, 
    76 A.3d 725
     (2013) (mistake
    by court regarding necessity of filing fee did not deprive
    it of subject matter jurisdiction to hear motion to open);
    Kores v. Calo, 
    126 Conn. App. 609
    , 620–21, 
    15 A.3d 152
     (2011) (defendants’ failure to pay filing fee did not
    deprive court of subject matter jurisdiction).9 Moreover,
    the defendant has failed to provide us with any authority
    to support her jurisdictional arguments. Accordingly,
    the defendant’s claim that the court lacked subject mat-
    ter jurisdiction to consider and grant the 2017 modifica-
    tion is without merit.
    II
    The defendant next claims that the court improperly
    failed to find fraud in denying her motion to open.
    Specifically, she argues that the plaintiff made false
    statements, which he knew to be untrue, with the intent
    to induce her to modify the alimony in 2017. Essentially,
    the defendant disagrees with the court’s finding that
    she failed to establish an element of fraud by clear and
    convincing evidence.
    We begin with the relevant legal principles. ‘‘Unless
    otherwise provided by law and except in such cases
    in which the court has continuing jurisdiction, a civil
    judgment or decree rendered in the Superior Court may
    not be opened or set aside unless a motion to open or
    set aside is filed within four months following the date
    on which it was rendered or passed. . . . This statute,
    however, does not abrogate the court’s common-law
    authority to open a judgment beyond the four month
    limitation upon a showing that the judgment was
    obtained by fraud, duress, or mutual mistake.’’ (Internal
    quotation marks omitted.) Karen v. Loftus, 
    210 Conn. App. 289
    , 297, 
    270 A.3d 126
     (2022); see generally General
    Statutes § 52-212a; Practice Book § 17-4. Simply stated,
    ‘‘[u]nder Connecticut law, although a motion to open
    a judgment normally must be filed within four months
    of entry of the judgment . . . a motion to open on the
    basis of fraud is not subject to this limitation . . . .’’

    cert. denied, 
    315 Conn. 910
    , 
    105 A.3d 901
     (2014).
    ‘‘Fraud consists in deception practiced in order to
    induce another to part with property or surrender some
    legal right, and which accomplishes the end designed.
    . . . The elements of a fraud action are: (1) a false
    representation was made as a statement of fact; (2) the
    statement was untrue and known to be so by its maker;
    (3) the statement was made with the intent of inducing
    reliance thereon; and (4) the other party relied on the
    statement to his detriment. . . . A court’s determina-
    tions as to the elements of fraud are findings of fact that
    we will not disturb unless they are clearly erroneous.’’

    (2016); see also Karen v. Loftus, supra, 
    210 Conn. App. 300
    . The defendant bore the burden of proving every
    element of fraud by clear and convincing evidence.

    327 Conn. 906
    , 
    170 A.3d 2
     (2017).
    In the present case, the court heard the testimony of
    the parties and considered the evidence.10 The court
    noted that the parties had exchanged emails regarding
    various financial scenarios prior to the execution of the
    2017 modification, including the payment of nonmodifi-
    able alimony to the defendant, even in the event that
    she remarried. ‘‘In defendant’s exhibit F, the plaintiff
    provides a draft agreement [which did not include the
    aforementioned alimony clause] to the defendant which
    he tells her to forward to her attorney. In the defendant’s
    response, she said her attorney reviewed a prior draft
    and told her not to sign the agreement. She continued
    that she was going to proceed with the agreement
    against the advice of counsel because she did not want
    to bargain.’’
    In finding that the defendant had failed to meet her
    burden of proof with respect to the fraud claim, the
    court stated: ‘‘The evidence submitted by the plaintiff
    shows the negotiation between the parties on the terms
    of the [2017 modification]. One email shows the defen-
    dant reviewed the agreement with her attorney who
    advised her not to sign the [2017 modification]. The
    defendant signed the [2017 modification] against legal
    advice. The defendant was not fraudulently induced to
    sign the agreement by the plaintiff.’’ The court specifi-
    cally found that the plaintiff did not make a false state-
    ment to the defendant with respect to the terms of the
    2017 modification or the execution of that document.
    ‘‘[I]n a case tried before a court, the trial judge is the
    sole arbiter of the credibility of the witnesses and the
    weight to be given specific testimony. . . . As such,
    the trial court is free to accept or reject, in whole or
    in part, the evidence presented by any witness, having
    the opportunity to observe the witnesses and gauge
    their credibility.’’ (Internal quotation marks omitted.)
    Longbottom v. Longbottom, 
    197 Conn. App. 64
    , 75, 
    231 A.3d 310
     (2020). Although the defendant asserts in her
    brief to this court that the plaintiff secured the 2017
    modification by fraud, she has failed to demonstrate
    that the court’s findings were clearly erroneous. As a
    result of the court’s finding that the defendant failed
    to establish that she was fraudulently induced to join
    the plaintiff’s efforts with respect to the 2017 modifica-
    tion of the dissolution judgment, a finding that has not
    been shown to be clearly erroneous, we cannot con-
    clude that Judge Moore abused her discretion in deny-
    ing the motion to open in 2020. ‘‘In general, abuse of
    discretion exists when a court could have chosen differ-
    ent alternatives but has decided the matter so arbitrarily
    as to vitiate logic, or has decided it based on improper or
    irrelevant factors.’’ (Internal quotation marks omitted.)
    State v. Jackson, 
    334 Conn. 793
    , 811, 
    224 A.3d 886
     (2020);
    see also Johnson v. Johnson, 
    203 Conn. App. 405
    , 415–
    16, 
    248 A.3d 796
     (2021). Accordingly, we conclude that
    the trial court did not abuse its discretion in denying
    the defendant’s motion to open.
    III
    Finally, the defendant presents a multitude of addi-
    tional arguments challenging Judge Moore’s denial of
    the 2020 motion to open. These additional arguments
    include challenges to the granting of the parties’ 2017
    joint motion to modify, namely, that Judge Novack (1)
    failed to find that a substantial change in circumstances
    had occurred before approving the 2017 stipulation that
    resulted in the modification of alimony, and (2) failed
    to conform the order to distinct and definite changes
    in the circumstances of the parties.11 In ruling on the
    2020 motion to open, Judge Moore rejected these argu-
    ments because ‘‘[t]he defendant failed to provide any
    credible evidence or case law to substantiate the addi-
    tional claims made in her motion.’’
    In this case, the defendant did not file her motion to
    open or an appeal from the underlying judgment in 2017
    within the twenty day appeal period. See Practice Book
    § 63-1. The defendant’s appeal from the denial of the
    2020 motion to open, therefore, ‘‘can test only whether
    the trial court abused its discretion in failing to open
    the judgment and not the propriety of the merits of
    the underlying judgment.’’ (Internal quotation marks
    omitted.) Charbonneau v. Charbonneau, 
    51 Conn. App. 311
    , 312–13, 
    721 A.2d 565
     (1998), cert. denied, 
    247 Conn. 964
    , 
    724 A.2d 1125
     (1999). We conclude that these chal-
    lenges raised in the defendant’s 2020 motion to open
    constitute an untimely and impermissible collateral
    attack on the 2017 actions of the court. We also agree
    with Judge Moore’s conclusion that the defendant failed
    to provide any credible evidence or case law to substan-
    tiate these claims. See Cimino v. Cimino, supra, 
    174 Conn. App. 8
    .
    The judgment is affirmed.
    In this opinion the other judges concurred.
    1
    The 2013 agreement specifically provided that each party has ‘‘received
    independent advice from counsel of his or her selection and has been fully
    informed of their legal rights and liabilities and believing this [a]greement
    to be fair, just and reasonable, has assented to its terms freely and volunta-
    rily . . . .’’
    2
    The 2017 modification further provided that the defendant was no longer
    obligated to contribute equally to the extracurricular, nonroutine activities
    of the parties’ children, to the college education expenses for two of the
    children, or be responsible for any of the children’s uninsured and unreim-
    bursed medical expenses.
    3
    Neither party filed a certified copy of the transcript from the December
    20, 2017 hearing with this court. See Practice Book § 63-8. The defendant
    included a copy of the nine page transcript in the appendix to her appellate
    brief. See Practice Book § 67-2 (d).
    4
    It does not appear that this motion has been adjudicated by the trial court.
    5
    General Statutes § 46b-86 (a) provides in relevant part that, ‘‘[u]nless
    and to the extent that the decree precludes modification, any final order
    for the periodic payment of permanent alimony or support, an order for
    alimony or support pendente lite or an order requiring either party to main-
    tain life insurance for the other party or a minor child of the parties may,
    at any time thereafter, be continued, set aside, altered or modified by the
    court upon a showing of a substantial change in the circumstances of either
    party . . . .’’ See also Olson v. Mohammadu, 
    310 Conn. 665
    , 671–72, 
    81 A.3d 215

    We note that had the defendant presented arguments before this court
    that implicate the subject matter jurisdiction of the trial court, we would
    need to consider whether the motion to open brought in 2020 was proper
    or whether it constituted an untimely collateral attack on the 2017 actions
    of the trial court.
    Our Supreme Court has recognized that, ‘‘[a]lthough challenges to subject
    matter jurisdiction may be raised at any time, it is well settled that [f]inal
    judgments are . . . presumptively valid . . . and collateral attacks on their
    validity are disfavored. . . . The reason for the rule against collateral attack
    is well stated in these words: The law aims to invest judicial transactions
    with the utmost permanency consistent with justice. . . . Public policy
    requires that a term be put to litigation and that judgments, as solemn
    records upon which valuable rights rest, should not lightly be disturbed or
    overthrown. . . . [T]he law has established appropriate proceedings to
    which a judgment party may always resort when he deems himself wronged
    by the court’s decision. . . . If he omits or neglects to test the soundness
    of the judgment by these or other direct methods available for that purpose,
    he is in no position to urge its defective or erroneous character when it is
    pleaded or produced in evidence against him in subsequent proceedings.
    Unless it is entirely invalid and that fact is disclosed by an inspection of
    the record itself the judgment is invulnerable to indirect assaults upon it.’’

    v. Vogel, 
    178 Conn. 358

    cert. denied, 
    272 Conn. 919
    , 
    866 A.2d 1289
     (2005). As a result of our conclu-
    sion that the purported defects set forth by the defendant, even if true,
    would not have deprived the trial court of subject matter jurisdiction, we
    need not consider whether her claim constitutes an improper collateral
    attack on the 2017 modification.
    7
    The defendant also made passing references in her appellate brief that
    the trial court lacked the statutory authority to grant the 2017 modification.
    ‘‘Although related, the court’s authority to act pursuant to a statute is differ-
    ent from its subject matter jurisdiction. The power of the court to hear and
    determine, which is implicit in jurisdiction, is not to be confused with the
    way in which that power must be exercised in order to comply with the
    terms of the statute.’’ (Internal quotation marks omitted.) Fusco v. Fusco,
    
    266 Conn. 649
    , 652, 
    835 A.2d 6
     (2003). Stated differently, ‘‘a failure to comply
    with statutory requirements will implicate only the court’s authority to act
    in accordance with the statute, not the court’s subject matter jurisdiction.’’

    213 Conn. App. 674
    , 691,

    , cert. denied, 
    345 Conn. 905
    ,            A.3d
    (2022). The defendant, however, has failed to set forth a complete and
    persuasive legal argument as to how the court improperly exercised its
    legal authority in granting the 2017 modification. Furthermore, raising this
    argument, which does not implicate the court’s subject matter jurisdiction,
    in the 2020 motion to open constitutes an improper collateral attack of the
    2017 orders of the trial court.
    Additionally, the defendant argued in her appellate brief that the plaintiff
    failed to provide the court with ‘‘any proper authority for granting the
    [2017 modification],’’ nor did he provide the court with a copy of the 2013
    agreement ordering him to pay alimony. We conclude that these contentions
    are meritless and do not address them further.
    8
    Although the legislature has amended § 46b-1 since the events underlying
    this appeal; see, e.g., Public Acts 2021, No. 21-78; those amendments have
    no bearing on the merits of this appeal. All references herein to § 46b-1 are
    to the current revision of the statute.
    9
    In her appellate brief, the defendant claims that the trial court’s lack of
    subject matter jurisdiction to modify the dissolution in 2017 was ‘‘entirely
    obvious,’’ and, therefore, her 2020 jurisdictional challenge did not amount
    to an untimely collateral attack. Within that discussion, she argues that
    the December 20, 2017 modification constituted an improper retroactive
    modification of alimony because the effective date of the $7000 monthly
    alimony was January 1, 2017. The defendant subsequently argues in her
    appellate brief that the court lacked the statutory authority to permit the
    parties to modify the alimony award retroactively.
    To the extent that the defendant contends that a claim of an improper
    retroactive modification of alimony implicated the subject matter jurisdic-
    tion of the trial court, we disagree. We emphasize that the Superior Court
    is provided, by our statutes, with ‘‘plenary and general subject matter jurisdic-
    tion over legal disputes in family relations matters, including custody and
    support.’’ (Internal quotation marks omitted.) O’Bryan v. O’Bryan, 
    67 Conn. App. 51
    , 54,

     (2001), aff’d, 
    262 Conn. 355
    , 
    813 A.2d 1001
     (2003).
    Regarding the defendant’s argument that the court lacked the authority to
    modify the alimony award retroactively, we conclude that this contention
    amounts to an untimely and improper collateral attack on the 2017 orders
    of the trial court. We also note that the trial court rejected this claim on
    the basis of the defendant’s failure to present any evidence or authority in
    support thereof. Finally, we note that the principle that alimony already
    accrued may not be modified applies only when a party seeks modification
    pursuant to § 46b-86, which was not the basis of the 2017 modification. See
    Mihalyak v. Mihalyak, 
    30 Conn. App. 516
    , 520, 
    620 A.2d 1327
     (1993).

    ‘‘In considering a motion to open the judgment on the basis of fraud
    . . . the trial court must first determine whether there is probable cause
    to open the judgment for the limited purpose of proceeding with discovery
    related to the fraud claim. . . . This preliminary hearing is not intended to
    be a full scale trial on the merits of the [moving party’s] claim. The [moving
    party] does not have to establish that he will prevail, only that there is
    probable cause to sustain the validity of the claim. . . . If the moving party
    demonstrates to the court that there is probable cause to believe that the
    judgment was obtained by fraud, the court may permit discovery. See Oneg-
    lia v. Oneglia, [
    14 Conn. App. 267
    , 269–70, 
    540 A.2d 713
     (1988)] (approving
    trial court’s position that [i]f the plaintiff was able to substantiate her allega-
    tions of fraud beyond mere suspicion, then the court would open the judg-
    ment for the limited purpose of discovery, and would later issue an ultimate
    decision on the motion to open after discovery had been completed and
    another hearing held).’’ (Internal quotation marks omitted.) Gaary v. Gillis,
    supra, 
    162 Conn. App. 256
    –57; see also Brody v. Brody, supra, 
    153 Conn. App. 634
     (party seeking to obtain discovery related to allegedly fraudulent
    conduct that transpired prior to entry of judgment must, consistent with
    aforementioned precedent, (1) move to open that judgment and (2) demon-
    strate to trial court that allegations of fraud are founded on probable cause).
    Our review of the record reveals that an Oneglia hearing was not held in
    the present case. Rather, the court held a hearing on the merits of the
    defendant’s motion to open based on fraud, without a request, or any objec-
    tion, from the parties for discovery pursuant to Oneglia. On appeal, the
    defendant does not challenge the absence of an Oneglia hearing in this mat-
    ter.
    11
    The defendant also claims that the 2017 modification was based on
    mutual mistake and therefore should have been opened. We agree with
    Judge Moore’s conclusion that the defendant failed to substantiate this claim
    with evidence and case law. We also note that the plaintiff testified that he
    would not have signed the 2017 modification in the absence of a change to
    the alimony award, and the court was free to credit this testimony.
    We conclude that the defendant has inadequately briefed her claims that
    (1) ‘‘the motion for order . . . should be opened and vacated by estoppel
    due to the nonmodifiable clause contained within paragraph 6.7 of the
    separation agreement,’’ and (2) the court improperly failed to award attor-
    ney’s fees. ‘‘We repeatedly have stated that [w]e are not required to review
    issues that have been improperly presented to this court through an inade-
    quate brief. . . . Analysis, rather than mere abstract assertion, is required
    in order to avoid abandoning an issue by failure to brief the issue properly.
    . . . [When] a claim is asserted in the statement of issues but thereafter
    receives only cursory attention in the brief without substantive discussion
    or citation of authorities, it is deemed to be abandoned.’’ (Internal quotation
