    LOUIS D. CORNEROLI v. RONALD W.
    KUTZ ET AL.
    (AC 39507)
    DiPentima, C. J., and Alvord and Eveleigh, Js.
    Syllabus
    The plaintiff sought to recover damages from the defendant attorney and
    the defendant law firm for their alleged legal malpractice in connection
    with their representation of the plaintiff in a probate matter involving
    the plaintiff’s claim to the proceeds of a sale of a certain painting. The
    painting had been purchased for $3 by the plaintiff’s cousin, D. After D
    died, the plaintiff entrusted the painting to B, who, unbeknownst to
    the plaintiff, sold the painting to A for approximately $1.2 million. A
    subsequently sold the painting to an unknown purchaser for millions
    of dollars more than what he paid for it. After the plaintiff learned about
    the sales of the painting, he brought an action for, inter alia, fraud and
    conversion in New York against B, A, and the unknown purchaser, which
    the New York court dismissed as to all parties except B. Subsequently,
    after commencing an action against, inter alia, the plaintiff, B, and A,
    the estate of D reached a settlement agreement for $2.4 million with A,
    and withdrew its claim against the plaintiff. The plaintiff brought a
    probate action claiming that he was entitled to 50 percent of the settle-
    ment because of an alleged former business partnership with D. The
    Probate Court granted the estate’s motion to disallow the plaintiff’s
    claim, and, thereafter, the defendants, on behalf of the plaintiff, filed
    an appeal of the Probate Court’s decision in the Superior Court. The
    estate filed a motion to dismiss the appeal for lack of subject matter
    jurisdiction on the ground that the appeal was untimely, which the trial
    court granted, and this court affirmed the dismissal. Subsequently, the
    plaintiff filed the present legal malpractice action on the basis of the
    defendants’ failure to timely prosecute the appeal from the Probate
    Court on his behalf. The trial court granted the defendants’ motion for
    summary judgment and rendered judgment thereon, from which the
    plaintiff appealed to this court. On appeal, he claimed, inter alia, that
    it was improper for the trial court to require expert testimony on the
    issue of causation and, in the alternative, the testimony of his expert,
    M, on the issue of causation was sufficient to defeat summary judg-
    ment. Held:
    1. The trial court properly rendered summary judgment in favor of the
    defendants on the basis of its conclusion that there was insufficient
    expert testimony on the issue of causation: Connecticut law generally
    requires the plaintiff in a legal malpractice action arising from prior
    litigation to prove, through expert testimony, that but for the alleged
    breach of duty, it was more likely than not that he would have prevailed
    in the underlying cause of action, and, in the present case, the plaintiff
    failed to prove that, had the defendants filed a timely appeal from the
    decision of the Probate Court, he was more likely than not to prevail
    on appeal to the Superior Court, as the opinions of M regarding causation
    were based on possibility, not probability, and M’s testimony, thus, failed
    to clearly express an opinion that had the defendants timely filed the
    appeal to the Superior Court, the plaintiff was more likely than not
    to prevail; furthermore, even if M expressed his opinions in terms of
    reasonable probabilities rather than possibilities, there was an inade-
    quate basis for any opinion by M on the issue of causation, as the Probate
    Court’s decision relied on the preclusive effect of the New York action,
    and because M was unfamiliar with the substance of that action, he had
    no basis on which he could opine, beyond mere speculation, as to what
    the result of an appeal to the Superior Court would have been.
    2. This court declined to review the plaintiff’s claim that the trial court
    improperly considered the defendants’ reply brief in support of the
    motion for summary judgment, which, contrary to its certification, was
    not received by the plaintiff’s counsel prior to the morning of the hearing
    on the defendants’ motion for summary judgment, that claim having
    been raised for the first time on appeal to this court and having been
    inadequately briefed; moreover, the plaintiff could not prevail on his
    claim that the trial court improperly permitted the defendants to file
    their surreply, as the record was clear that the defendants sought and
    received the court’s permission to file the surreply.

    Procedural History
    Action to recover damages for legal malpractice, and
    for other relief, brought to the Superior Court in the
    judicial district of Middlesex, where the court, Auri-
    gemma, J., granted the defendants’ motion for summary
    judgment and rendered judgment thereon, from which
    the plaintiff appealed to this court. Affirmed.
    Daniel H. Kennedy III, with whom was R. Bartley

    Michelle Napoli-Lipsky, for the appellees (defendants).
    Opinion
    ALVORD, J. The plaintiff in this legal malpractice
    action, Louis D. Corneroli, appeals from the summary
    judgment rendered by the trial court in favor of the
    defendants, Ronald W. Kutz and Kutz & Prokop, LLP.
    On appeal, the plaintiff claims that the court improperly
    (1) rendered summary judgment in favor of the defen-
    dants on the basis of its conclusion that there was
    insufficient expert testimony on the issue of causation,
    and (2) considered certain documents filed by the
    defendants. We affirm the judgment of the trial court.
    The plaintiff’s present appeal marks yet another chap-
    ter in a saga of extensive litigation over the last twenty
    years. The litigation arises out of the serendipitous pur-
    chase of an original John Singer Sargent painting by the
    plaintiff’s late cousin, Salvatore D. D’Amico (decedent).
    The defendants represented the plaintiff in a probate
    matter involving the plaintiff’s claim to the proceeds of
    the sale of that painting, and in subsequent appeals to
    the Superior and Appellate Courts.
    In its memorandum of decision, the trial court set
    forth the following findings of the Probate Court. ‘‘The
    decedent frequented tag sales in hopes of finding under-
    valued assets. At some point in 1978, he acquired for
    $3 a painting which turned out to be an original [John
    Singer] Sargent painting called ‘Carmencita Dancing’
    worth several million dollars. The problem encountered
    by the decedent was that he was unable to get the
    painting authenticated and thus was unable to realize
    the full value of the painting during his lifetime. At some
    point, the decedent’s cousin, Louis Corneroli, began
    working with the decedent, driving him around and also
    becoming involved in his various projects, including the
    effort to authenticate the Sargent painting. Mr. Cor-
    neroli contends that he and the decedent had a partner-
    ship in which they agreed to work on matters together
    and equally split the profits realized from their activity.
    The estate of Salvatore D. D’Amico strenuously denies
    any such partnership. . . .
    ‘‘After the decedent died, Mr. Corneroli took posses-
    sion of the painting and entrusted it to Mark Borghi,
    who owned and operated an art gallery in New York
    and who was in a better position to have the painting
    authenticated than Mr. Corneroli. . . . Unbeknownst
    to Mr. Corneroli, Mr. Borghi sold the painting to a Mr.
    [Warren] Adelson, another art dealer who specialized
    in Sargent paintings, for approximately $1.2 million.
    Mr. Adelson turned around and sold the painting for
    millions more than what he paid for it, again without
    the knowledge of Mr. Corneroli. At some point, Mr.
    Corneroli learned of the sale of the painting and filed
    the Corneroli Complaint in New York, suing Mr. Borghi,
    Mr. Adelson and John Doe, the still unknown purchaser
    of the painting, alleging, inter alia, fraud, conversion
    and breach of contract claims. Judge Ira Gammerman,
    of the Supreme Court of the state of New York, after
    hearing testimony from Mr. Corneroli on the Corneroli
    complaint, found that Mr. Corneroli testified that he
    had an agreement with Mr. Borghi under which the
    parties were to divide the sales price of the sale of
    the painting with Mr. Borghi receiving half and Mr.
    Corneroli receiving half. . . . Mr. Corneroli freely
    acknowledged during the trial that both the decedent
    while living and his estate had a 50% interest in the
    painting. . . . The Corneroli complaint, however,
    alleged that Mr. Corneroli was the sole owner of the
    painting. . . .
    ‘‘After hearing the testimony of Mr. Corneroli, the
    New York court dismissed the case as to all parties
    except Mr. Borghi. It is crystal clear from the transcript
    that the claim against Mr. Adelson was dismissed ‘with
    prejudice.’ . . . . The New York court further found
    the potential recovery from Mr. Borghi in Mr. Cor-
    neroli’s favor to be approximately $313,000, which was
    roughly one quarter of the sales price of the sale of
    the painting from Mr. Borghi to Mr. Adelson. . . . Mr.
    Corneroli acknowledged that he received about that
    amount in either paintings or cash in July, 2003, and
    that the parties thereafter returned to Connecticut to
    open an estate for the decedent so that the estate could
    pursue its share.
    ‘‘The administrators of the newly-opened estate of
    D’Amico took a vastly different view of the history than
    Mr. Corneroli. Based on their belief that Mr. Corneroli
    had denied knowledge as to the location of the painting
    shortly after the death of the decedent and further had
    not disclosed that he had given the painting to the New
    York art dealer until shortly before the proceedings in
    New York occurred, the estate took the position that
    there never was any partnership and that Mr. Corneroli
    had absconded with the painting after the decedent
    died. The estate filed a lawsuit in federal court in
    December, 2003, which suit was dismissed without prej-
    udice. A new suit was filed in July, 2005, in which the
    estate sued, inter alia, Mr. Corneroli, Mr. Borghi and
    Mr. Adelson, alleging that the painting had been stolen
    by Mr. Corneroli and that title never passed due to this
    fact. The estate sought a declaratory judgment that it
    was the owner of the painting, a replevin of the painting
    back to the estate and damages from Mr. Corneroli for
    his alleged misdeeds. Mr. Corneroli filed an answer with
    special defenses to the complaint in which he generally
    alleged that his actions were taken as a partner of the
    decedent and that he did not steal the painting. Mr.
    Corneroli did not, however, file a counterclaim or seek
    to join the [estate] in its claims against the other defen-
    dants, including Mr. Adelson.
    ‘‘A two day mediation to resolve the case occurred
    on December 11 [and] 12 at New Britain Superior Court.
    Counsel for Mr. Corneroli attended on the first day but
    did not return for the second day. The remaining parties
    reached an agreement on the second day, which
    involved Mr. Adelson paying the [estate] the sum of
    $2.4 million. In a lengthy agreement put on the record,
    the [estate] indicated that the settlement was subject
    to the [estate] obtaining a release of Mr. Corneroli and
    the Probate Court approving the settlement as well. It
    does not appear any formal notice was provided to Mr.
    Corneroli of the settlement, however, his attorney was
    called in connection with executing a release, which
    was refused. The Probate Court hearing occurred and
    the settlement was approved by the Probate Court. The
    case against Mr. Corneroli was withdrawn. Thereafter,
    Mr. Corneroli, in reviewing the probate file, learned
    about the settlement amount for the first time. He filed
    a claim with the estate dated August 23, 2007, in which
    he stated that he was a partner with the decedent in
    attempting to get the painting authenticated and that
    their agreement was that any funds received as a result
    of getting the painting authenticated would be split
    equally and thus he was entitled to receive 50 [percent]
    of the 2.4 million settlement.’’ (Emphasis omitted; foot-
    note omitted.) The estate moved to disallow the plain-
    tiff’s claim as untimely.
    The Probate Court assumed for purposes of deciding
    the motion that the plaintiff’s claim of partnership was
    true, but nonetheless granted the estate’s motion to
    disallow the plaintiff’s claim. The court concluded that
    ‘‘if, in fact, a partnership existed, the New York action
    represented the one opportunity it had to obtain a recov-
    ery in this matter against Mr. Adelson,’’ and ‘‘the dis-
    missal of the New York action against Mr. Adelson,
    with prejudice, indicates to the court that Mr. Cor-
    neroli’s future opportunity to pursue a claim against
    Mr. Adelson, either individually or as part of a partner-
    ship, has been forever precluded.’’ The court further
    determined that the plaintiff or, alternatively, the part-
    nership, ‘‘had no claim against Mr. Adelson,’’ and ‘‘upon
    the conclusion of the New York litigation, the last
    remaining asset of any ‘partnership’ was the $300,000
    claim against Mr. Borghi, which Mr. Corneroli testified
    to, but which could not be the subject of any award
    . . . as the estate was not a party plaintiff in the action.
    Mr. Corneroli cannot claim any interest in that claim
    as he received his judgment in that amount against Mr.
    Borghi already.’’
    On the basis of its conclusion that ‘‘the New York
    litigation fully and finally resolved any issues of partner-
    ship assets and . . . the fruits of the litigation brought
    thereafter by the estate in no way can be determined
    to be considered a partnership asset as a matter of law,’’
    the court characterized the plaintiff’s claim against the
    estate as an attempt to claim ‘‘an interest in a partner-
    ship asset which, as a matter of law, is not a partnership
    asset.’’ The Probate Court granted the estate’s motion
    to disallow the plaintiff’s claim and, on March 27, 2008,
    sent notice of its decision to the parties and counsel.
    On June 4, 2008, the defendants, on behalf of the
    plaintiff, filed an appeal of the Probate Court’s decision
    in the Superior Court. The estate moved to dismiss the
    appeal for lack of subject matter jurisdiction, claiming
    that the appeal was untimely. The court granted the
    motion and dismissed the appeal as untimely.1 This
    court affirmed the dismissal, and our Supreme Court
    declined to hear the matter. See Corneroli v. D’Amico,
    
    116 Conn. App. 59
    , 67, 
    975 A.2d 107
    , cert. denied, 
    293 Conn. 928
    , 
    980 A.2d 909
     (2009).
    In 2012, the plaintiff filed this legal malpractice action
    on the basis of the defendants’ failure to timely prose-
    cute the appeal from the Probate Court on his behalf.
    In his fourth amended complaint, the plaintiff alleged
    that the defendants were negligent in their representa-
    tion of him in the underlying probate matter, and that
    ‘‘[h]ad the defendants filed a timely appeal, the plaintiff
    would have had a reasonable basis for a successful
    outcome of the de novo appeal.’’
    On April 28, 2016, the defendants moved for summary
    judgment, arguing that no genuine issue of material fact
    existed because the plaintiff had ‘‘failed to disclose any
    expert who can opine on the issue of proximate cause,
    a necessary element in any legal malpractice action.’’
    On July 27, the court issued a memorandum of decision,
    in which it granted the defendants’ motion. This
    appeal followed.
    I
    The plaintiff first claims that the trial court improp-
    erly rendered summary judgment in favor of the defen-
    dants on the basis of its conclusion that there was
    insufficient expert testimony to create a genuine issue
    of material fact as to causation. Specifically, he argues
    that it was improper for the court to require expert
    testimony on the issue of causation, and that even if it
    were proper, his expert’s testimony on the issue of
    causation was sufficient to defeat summary judgment.
    We disagree.
    The following procedural history is relevant to our
    resolution of this claim. During discovery, the plaintiff
    disclosed two experts: (1) Attorney John A. Berman, a
    retired probate judge, and (2) Professor Jeremy
    McClane, a professor at the University of Connecticut
    School of Law.2
    During his deposition, Professor McClane testified
    that he is an expert on partnership law. He extensively
    opined on the issue of partnership in the underlying
    probate matter, testifying as to his belief that there was
    ‘‘a reasonable basis for a successful outcome of the
    appeal’’ because there was ‘‘both a reasonable basis
    that Corneroli would have been able to show that there
    was a partnership and that the painting was partnership
    property and that any disposition or any money coming
    out of a disposition of that painting was also partnership
    property . . . .’’ When questioned on the issue of cau-
    sation, the following colloquy occurred:
    ‘‘[The Defendants’ Counsel]: Can you state to a rea-
    sonable degree of probability that the result of any
    appeal—of the outcome of an appeal in the Superior
    Court would have been different as opposed to [the
    Probate Court’s] decision?
    ***
    ‘‘[Professor McClane]: I mean, it’s hard to say what
    the outcome of a litigation would be just because there
    are so many moving parts, so many things involved, the
    skill of the lawyers, you know, what the jury thinks of
    the witnesses, but I think that there is certainly a very
    good chance that the outcome would have been differ-
    ent than what was indicated in [the Probate Court’s]
    opinion.
    ‘‘[The Defendants’ Counsel]: But can you say to a
    reasonable degree of probability that it’s more likely
    than not the outcome would have been different?
    ***
    ‘‘[Professor McClane]: I think there’s a very good
    chance the outcome would have been different. I don’t
    know that I can say more likely than not. I’m not saying
    it is or it isn’t. I just don’t think I can really say simply
    because, you know, if you were to believe everything—
    if a finder of fact were to believe everything that is in
    all of this testimony and all of these document, then I
    think, yes, there’s a—it’s likely that the outcome would
    be different because I think they would understand that
    this is a partnership asset and the claim is really about
    liquidating the partnership asset and getting the value
    for it. But I can’t opine on whether or not people are
    going to believe one set of testimony over another.
    ‘‘[The Defendants’ Counsel]: Okay. So sitting here
    today, you can’t testify—you can only testify you believe
    there’s a very good chance the outcome would have
    been different, not that it’s more likely than not it would
    have been different?
    ***
    ‘‘[Professor McClane]: I can say that if at a trial every-
    body believed—that all of the testimony of Mr. Cor-
    neroli were believed, then I think it’s more likely
    than not.
    ‘‘[The Defendants’ Counsel]: And what are the
    chances that all of his testimony would be believed?
    ***
    ‘‘[Professor McClane]: I don’t have the crystal ball to
    say that, unfortunately.’’
    On April 28, 2016, the defendants moved for summary
    judgment. In their memorandum in support of the
    motion, the defendants argued that no genuine issue
    of material fact existed with respect to the issue of
    causation because ‘‘neither of the plaintiff’s disclosed
    experts have offered testimony that the plaintiff would
    have prevailed on legal and/or factual grounds had the
    probate appeal been timely commenced and had the
    Superior Court conducted a trial de novo on the merits
    of [the] plaintiff’s claims.’’ With respect to Professor
    McClane’s testimony on the issue of causation, the
    defendants argued that he ‘‘could not state to a reason-
    able degree of probability that the outcome of a timely
    appeal would have differed from [the Probate Court’s]
    decision.’’ The defendants highlighted Professor
    McClane’s testimony that: (1) it was ‘‘hard to say what
    the outcome of a litigation would be just because there
    are so many moving parts’’; (2) he did not know if he
    could say ‘‘more likely than not’’ that the outcome would
    have been different; (3) he was not ‘‘saying it is or it
    isn’t’’ more likely than not; (4) he could not opine as
    to whether a fact finder would believe ‘‘one set of testi-
    mony over another’’; and (5) he did not ‘‘have the crystal
    ball’’ to evaluate the chances of the fact finder believing
    the plaintiff’s testimony. The defendants noted that the
    Probate Court assumed for purposes of its analysis that
    a partnership existed between the plaintiff and the dece-
    dent with respect to the painting, and that Professor
    McClane could not ‘‘articulate any basis on which the
    Superior Court would have reached a different result.’’
    The defendants further argued that Professor McClane’s
    testimony spoke to ‘‘possibilities, not probabilities,
    which is legally insufficient to meet the burden of
    proof,’’ and accordingly, the plaintiff had failed to estab-
    lish a prima facie case of legal malpractice.
    The trial court rendered summary judgment in favor
    of the defendants on July 27, 2016. In its memorandum
    of decision, the court concluded that ‘‘Professor
    McClane could not state to a reasonable degree of prob-
    ability that the outcome of a timely appeal would have
    differed from [the Probate Court’s] decision,’’ and high-
    lighted his testimony that he did not know if he could
    say ‘‘more likely than not’’ that the outcome would have
    been different, and that he was not ‘‘saying it is or it
    isn’t’’ more likely than not. The court further concluded
    that ‘‘Professor McClane failed to offer any testimony
    as to his bases for challenging the decision of [the
    Probate Court].’’ Specifically, the court noted that Pro-
    fessor McClane’s testimony did not provide a basis for
    challenging the Probate Court’s conclusion that the
    New York action represented the plaintiff’s only oppor-
    tunity to recover against Adelson under any legal the-
    ory. The court concluded: ‘‘[N]either [Professor
    McClane’s] deposition testimony nor his affidavit pro-
    vide any basis to support the opinion that Mr. Corneroli
    would probably have prevailed in his de novo probate
    appeal. To the contrary, Professor McClane testified
    that he was not familiar with the substance of [the
    Probate Court’s] opinion or Mr. Corneroli’s litigation
    history vis-a`-vis the painting at issue. The opinion of
    the Probate Court was rational, logical and based on
    Mr. Corneroli’s prior litigation with respect to the paint-
    ing. In order to decide contrary to the opinion of [the
    Probate Court], a Superior Court Judge would certainly
    need a good reason. Professor McClane has completely
    failed to articulate such [a] reason. Thus, he provided
    no basis for any opinion as to causation. Without such
    a basis there is no genuine issue of material fact. Sum-
    mary judgment enters in favor of the defendants.’’
    We begin with the applicable standard of review and
    principles of law that guide our analysis. ‘‘Practice Book
    § 17-49 provides that summary judgment shall be ren-
    dered forthwith if the pleadings, affidavits and any other
    proof submitted show that there is no genuine issue as
    to any material fact and that the moving party is entitled
    to judgment as a matter of law. In deciding a motion
    for summary judgment, the trial court must view the
    evidence in the light most favorable to the nonmoving
    party. . . . The party moving for summary judgment
    has the burden of showing the absence of any genuine
    issue of material fact and that the party is, therefore,
    entitled to judgment as a matter of law. . . . Our
    review of the trial court’s decision to grant the defen-
    dant’s motion for summary judgment is plenary. . . .
    Summary judgment in favor of a defendant is proper
    when expert testimony is necessary to prove an essen-
    tial element of the plaintiff’s case and the plaintiff is
    unable to produce an expert witness to provide such
    testimony. . . .
    ‘‘Malpractice is commonly defined as the failure of
    one rendering professional services to exercise that
    degree of skill and learning commonly applied under
    all the circumstances in the community by the average
    prudent reputable member of the profession with the
    result of injury, loss, or damage to the recipient of those
    services . . . . Generally, a plaintiff alleging legal mal-
    practice must prove all of the following elements: (1)
    the existence of an attorney-client relationship; (2) the
    attorney’s wrongful act or omission; (3) causation; and
    (4) damages. . . .
    ‘‘The essential element of causation has two compo-
    nents. The first component, causation in fact, requires
    us to determine whether the injury would have occurred
    but for the defendant’s conduct. . . . The second com-
    ponent, proximate causation, requires us to determine
    whether the defendant’s conduct is a substantial factor
    in bringing about the plaintiff’s injuries. . . . That is,
    there must be an unbroken sequence of events that tied
    [the plaintiff’s] injuries to the [defendant’s conduct].
    . . . This causal connection must be based [on] more
    than conjecture and surmise. . . . [N]o matter how
    negligent a party may have been, if his negligent act
    bears no [demonstrable] relation to the injury, it is not
    actionable . . . .
    ‘‘The existence of the proximate cause of an injury
    is determined by looking from the injury to the negligent
    act complained of for the necessary causal connection.
    . . . In legal malpractice actions arising from prior liti-
    gation, the plaintiff typically proves that the . . . attor-
    ney’s professional negligence caused injury to the
    plaintiff by presenting evidence of what would have
    happened in the underlying action had the [attorney]
    not been negligent. This traditional method of pre-
    senting the merits of the underlying action is often
    called the case-within-a-case. . . . More specifically,
    the plaintiff must prove that, in the absence of the
    alleged breach of duty by her attorney, the plaintiff
    would have prevailed [in] the underlying cause of action
    and would have been entitled to judgment. . . . To
    meet this burden, the plaintiff must produce evidence
    explaining the legal significance of the attorney’s failure
    and the impact this had on the underlying action.’’ (Cita-
    tions omitted; emphasis omitted; footnote omitted;

    tavros,

     (2016).
    We first address the plaintiff’s argument that it was
    improper to require expert testimony on the issue of
    causation because the ‘‘probability of success of the
    underlying case is an ultimate issue.’’ According to the
    plaintiff, ‘‘[i]t would be inappropriate for Mr. Corneroli
    to disclose an expert on the underlying issue, as the
    court can directly decide the merits of the underlying
    case.’’ This argument is entirely without merit.
    Section 7-3 (a) of the Connecticut Code of Evidence
    provides in relevant part: ‘‘Testimony in the form of an
    opinion is inadmissible if it embraces an ultimate issue
    to be decided by the trier of fact, except that . . . an
    expert witness may give an opinion that embraces an
    ultimate issue where the trier of fact needs expert assis-
    tance in deciding the issue.’’ In regard to the issue of
    causation in legal malpractice cases, our Supreme Court
    recently ruled that ‘‘although there will be exceptions
    in obvious cases, expert testimony . . . is a general
    requirement for establishing the element of causation
    in legal malpractice cases. Because a determination of
    what result should have occurred if the attorney had not
    been negligent usually is beyond the field of ordinary
    knowledge and experience possessed by a juror, expert
    testimony generally will be necessary to provide the
    essential nexus between the attorney’s error and the
    plaintiff’s damages.’’ (Footnotes omitted.) Bozelko v.
    Papastavros, supra, 
    323 Conn. 284
    –85. In Bozelko, our
    Supreme Court recognized the need for expert assis-
    tance to decide the issue of whether an attorney’s
    alleged malpractice caused the claimed injury. In light
    of the holding in Bozelko, we reject the plaintiff’s argu-
    ment that it is improper to permit an expert to testify
    as to his opinion on causation in a legal malpractice
    case.3 See also Dixon v. Bromson & Reiner, 
    95 Conn. App. 294
    , 299–300, 
    898 A.2d 193
     (2006) (‘‘in a legal
    malpractice case such as this, an expert witness is nec-
    essary to opine whether the defendant’s alleged breach
    of care proximately caused the plaintiff’s alleged loss
    or damages’’).4
    Because we have concluded that, to defeat summary
    judgment, the plaintiff was required to present expert
    testimony to prove causation, we must now examine
    the substance of Professor McClane’s testimony to
    determine whether summary judgment was proper.
    ‘‘Expert opinions must be based upon reasonable proba-
    bilities rather than mere speculation or conjecture if
    they are to be admissible in establishing causation. . . .
    To be reasonably probable, a conclusion must be more
    likely than not. . . . Whether an expert’s testimony is
    expressed in terms of a reasonable probability that an
    event has occurred does not depend upon the semantics
    of the expert or his use of any particular term or phrase,
    but rather, is determined by looking at the entire sub-
    stance of the expert’s testimony.’’ (Internal quotation
    marks omitted.) Drew v. William W. Backus Hospital,
    
    77 Conn. App. 645
    , 662–63, 
    825 A.2d 810
    , cert. granted,
    
    265 Conn. 909
    , 
    831 A.2d 249
     (2003) (appeal withdrawn
    December 22, 2003).
    As we have noted, Connecticut law generally requires
    the plaintiff in a legal malpractice action arising from
    prior litigation to prove, through expert testimony, that
    but for the alleged breach of duty, it was more likely
    than not that he would have prevailed in the underlying
    cause of action. In this case, the plaintiff was required
    to prove that, had the defendants filed a timely appeal
    from the decision of the Probate Court, he was more
    likely than not to prevail on appeal to the Superior
    Court. On appeal to this court, the plaintiff argues that
    ‘‘Professor McClane’s deposition testimony and expert
    disclosure make it clear that he believes with a reason-
    able probability that Mr. Corneroli would have prevailed
    in the de novo probate appeal.’’ We disagree.
    Reviewing in its entirety Professor McClane’s testi-
    mony, and viewing that testimonial evidence in a light
    most favorable to the plaintiff, we conclude that the
    plaintiff failed to produce the expert testimony neces-
    sary to prove the essential element of causation in his
    legal malpractice action. The substance of Professor
    McClane’s testimony on the issue of causation can be
    summarized as follows: (1) he found it ‘‘hard to say
    what the outcome of a litigation would be just because
    there are so many moving parts’’; (2) there was ‘‘cer-
    tainly a very good chance’’ that the plaintiff would have
    prevailed on appeal from the Probate Court; (3) even
    though he thought that there was a ‘‘very good chance’’
    that the plaintiff would have prevailed on appeal, he
    did not know that he could ‘‘say more likely than not’’;
    (4) he was not saying that ‘‘it is or it isn’t’’ more likely
    than not that the plaintiff would prevail on appeal; (5)
    he could not ‘‘opine on whether people are going to
    believe one set of testimony over another’’; (6) if, at a
    trial, ‘‘all of the testimony of Mr. Corneroli were
    believed,’’ it was ‘‘more likely than not’’ that he would
    prevail; and (7) he did not have a ‘‘crystal ball’’ to opine
    on the chances of the fact finder believing all of the
    plaintiff’s testimony. It is clear from this testimony that
    Professor McClane’s opinions regarding causation were
    based on possibility, not probability. Those possibilities
    depended on the ‘‘many moving parts’’ that Professor
    McClane described, which included: (1) the skill of the
    lawyers; (2) the jury’s opinion of the witnesses; (3) the
    likelihood of the fact finder believing the testimony
    and documents; (4) the jury’s understanding that the
    painting was a partnership asset; (5) the jury’s under-
    standing that ‘‘the claim is really about liquidating the
    partnership asset and getting the value for it’’; and (6)
    the likelihood of ‘‘everybody’’ believing the testimony
    of the plaintiff. Professor McClane’s testimony fails to
    clearly express an opinion that had the defendants
    timely filed the appeal to the Superior Court, the plain-
    tiff was more likely than not to prevail.5
    Furthermore, even if we were to assume that Profes-
    sor McClane expressed his opinions in terms of reason-
    able probabilities rather than possibilities, we conclude
    that there was an inadequate basis for any opinion by
    Professor McClane on the issue of causation. The Pro-
    bate Court largely based its decision on its observation
    that ‘‘if, in fact, a partnership existed, the New York
    action represented the one opportunity it had to obtain
    a recovery in this matter against Mr. Adelson.’’ As the
    trial court noted, Professor McClane failed to review
    the New York decision. Professor McClane testified that
    he understood the plaintiff’s involvement in the New
    York litigation and he understood that the plaintiff’s
    claim against Mr. Adelson was dismissed with preju-
    dice, but that, in addition to not reading the New York
    court’s decision, he also did not: (1) read the transcripts
    of that case; (2) review the evidence presented in that
    case; or (3) know what the cause of action was in
    that case. When questioned about his opinion as to the
    Probate Court’s conclusion that the New York action
    precluded the probate claim, the following colloquy
    occurred:
    ‘‘[The Defendants’ Counsel]: And in the last paragraph
    of page three, exhibit 4, it begins, quote, ‘The plain
    conclusion reached by this court, however, is that if,
    in fact, a partnership existed, the New York action rep-
    resented the one opportunity it had to obtain a recovery
    in this matter against Mr. Adelson,’ close quote. Do you
    see that?
    ‘‘[Professor McClane]: Yes, I do.
    ***
    ‘‘[The Defendants’ Counsel]: Do you agree as to
    that conclusion?
    ‘‘[Professor McClane]: I don’t actually have any basis
    on which to evaluate that conclusion, simply because
    I don’t know what the action—what the specific cause
    of action was in New York.
    ‘‘For example, were they suing for a breach of a
    contract of sale between the partnership and Mr. Bor-
    ghi? In that case, then that claim is obviously foreclosed.
    But if there was another sort of duty, some kind of
    unlawful conversion or something like that, then that’s
    not foreclosed by the New York action.
    ‘‘But, again, I just don’t know, right. So I don’t want
    to speculate.
    ‘‘[The Defendants’ Counsel]: And you’re not here to
    testify about the effect of that decision; correct?
    ‘‘[Professor McClane]: Yeah.’’ (Emphasis added.)
    The question with respect to the issue of causation
    is whether, on appeal, the plaintiff was more likely than
    not to prevail. The result in the Probate Court was
    determined in large part by the preclusive effect of the
    New York action. Professor McClane conceded that to
    opine on the preclusive effect of the New York action,
    he would have to engage in speculation. Since the Pro-
    bate Court’s decision relied on the preclusive effect
    of the New York action, and Professor McClane was
    unfamiliar with the substance of that action, he had no
    basis on which he could opine, beyond mere specula-
    tion, as to what the result of an appeal to the Superior
    Court would have been.6 See, e.g., Weinstein v.
    Weinstein, 
    18 Conn. App. 622
    , 636–37, 
    561 A.2d 443
    (1989) (where expert did not examine books or records
    of business, trial court did not abuse discretion by refus-
    ing to allow testimony regarding valuation of business
    because there was insufficient basis for opinion on
    that issue).
    We conclude that the defendants established the lack
    of a genuine issue of material fact concerning the issue
    of causation, such that they were entitled to judgment
    as a matter of law. Even viewing the evidence in the
    light most favorable to the plaintiff, we conclude that
    he failed to present evidence that would raise such an
    issue. Accordingly, the court properly rendered sum-
    mary judgment in favor of the defendants.7
    II
    The plaintiff also claims that the trial court improp-
    erly: (1) considered the defendants’ reply brief in sup-
    port of the motion for summary judgment, and (2)
    permitted the defendants to file a surreply brief in fur-
    ther support of the motion for summary judgment.
    These claims are meritless.
    The following procedural history is relevant to our
    resolution of these claims. The defendants filed their
    motion for summary judgment and supporting memo-
    randum on April 28, 2016. On June 6, the plaintiff filed
    his memorandum in opposition to the defendants’
    motion for summary judgment. On June 14, the defen-
    dants filed a reply brief in further support of their
    motion for summary judgment. On the last page of the
    reply brief, the defendants’ counsel certified that a copy
    was ‘‘mailed or electronically delivered on this 14th day
    of June, 2016, to all counsel . . . .’’
    On June 20, the court heard argument on the defen-
    dants’ motion for summary judgment. At that time, the
    plaintiff’s counsel represented to the court that
    although the defendants’ counsel certified that a copy
    of the reply brief ‘‘was e-mailed and sent via mail to
    both my office and [co-counsel’s] office,’’ they had not
    received a copy. Counsel further represented that she
    discovered that the reply brief had been filed that morn-
    ing when a paralegal checked the court docket prior
    to the hearing. Counsel argued that this was prejudicial,
    as she had not yet researched any of the cases cited
    in the defendants’ reply brief. Counsel requested the
    court’s permission to file a surreply brief within one
    week, stating: ‘‘[W]e’re okay moving forward with the
    argument today, but we would like a chance to respond
    without them then responding again, but I think out of
    fairness.’’8 The court granted the request of the plain-
    tiff’s counsel to file a surreply brief within a week of
    the hearing.
    On June 27, as permitted by the court, the plaintiff
    filed a surreply brief in opposition to the defendants’
    motion for summary judgment. The plaintiff attached
    to his surreply, as exhibit B, an affidavit of Professor
    McClane, which stated:
    ‘‘On March 31, 2016, I sat for a deposition by Defen-
    dants’ counsel in Hartford, Connecticut. . . .
    ‘‘I was questioned by the Defendants’ counsel as to
    the probability that Mr. Corneroli would have been suc-
    cessful on his appeal from Probate Court had the Defen-
    dants filed a timely appeal. I testified that there was a
    reasonable basis for a successful outcome of that appeal
    and that there was a very good chance the outcome
    would have been different than it was in the Probate
    Court. I believe it was reasonably probable. . . .
    ‘‘When queried as to whether it was ‘more likely than
    not’ I did not understand the terminology in the context
    of the pending legal malpractice action. As I now under-
    stand the Defendants’ position, I am comfortable that
    my reasonable probability standard well exceeds more
    likely than not. . . .
    ‘‘It was my opinion on March 31, 2016, and it is still
    my opinion, that it is more likely than not that Mr.
    Corneroli would have been successful had the Defen-
    dants filed a timely appeal.’’
    On June 30, the defendants filed their own surreply
    brief in further support of the motion for summary
    judgment. The defendants argued that exhibit B to the
    plaintiff’s surreply constituted a ‘‘sham affidavit,’’ an
    ‘‘affidavit in opposition to a motion for summary judg-
    ment that contradicts the affiant’s prior deposition testi-
    mony,’’ which the court should reject. The defendants
    acknowledged that Connecticut courts had not
    expressly adopted the sham affidavit rule but cited
    cases in which courts had applied the ‘‘underlying ratio-
    nale for the rule’’ in deciding motions for summary
    judgment. The defendants argued that the affidavit was
    an attempt to ‘‘submit contradictory testimony from
    [the plaintiff’s] own expert to avoid the entry of sum-
    mary judgment,’’ and that the affidavit was improper,
    untimely, lacked credibility, and could not ‘‘be
    explained as the result of confusion.’’ The defendants
    argued that the affidavit was an attempt to materially
    alter Professor McClane’s testimony and, alternatively,
    violated the court’s scheduling order as the introduction
    of additional testimony from an expert after expert
    discovery concluded.
    On July 1, the plaintiff filed an objection to the defen-
    dants’ surreply. The plaintiff cited Practice Book § 11-
    10,9 which requires a party seeking to file a surreply
    to obtain permission from the court, and argued that
    because the defendants had failed to seek permission
    to file their surreply, it was not properly before the
    court. Also on July 1, the defendants filed a caseflow
    request, in which they requested the court’s permission
    to file a surreply. The defendants listed as a reason for
    the request: ‘‘Plaintiff’s counsel offered an affidavit from
    his expert which contradicts prior testimony. Defen-
    dants request that the court give due consideration to
    a surreply addressed to issues raised by the plaintiff’s
    brief including the expert affidavit.’’ On July 18, the
    court overruled the plaintiff’s objection.10
    The plaintiff argues, for the first time on appeal, that
    the court improperly considered the defendants’ reply
    brief, which, contrary to its certification, was not
    received by the plaintiff’s counsel prior to the morning
    of the hearing on the defendants’ motion for summary
    judgment. We conclude that the plaintiff has aban-
    doned, by failing to adequately brief, this claim. The
    plaintiff devotes three sentences of his brief to this
    issue, in which he does not cite or analyze any case
    law but merely makes bare factual assertions. See foot-
    note 7 of this opinion. Furthermore, ‘‘[t]o review claims
    articulated for the first time on appeal and not raised
    before the trial court would be nothing more than a
    trial by ambuscade of the trial judge.’’ (Internal quota-
    tion marks omitted.) Bragdon v. Sweet, 
    102 Conn. App. 600
    , 607, 
    925 A.2d 1226
     (2007). Accordingly, we decline
    to review this claim.
    The plaintiff also argues that the court improperly
    permitted the defendants to file the June 30 surreply.
    Specifically, he argues that, because the defendants
    ‘‘neither made any oral request nor filed a request for
    leave for permission to make such a filing’’ pursuant
    to Practice Book § 11-10, the surreply ‘‘was not properly
    before the court.’’ We disagree.
    Practice Book § 11-10 (c) provides: ‘‘Surreply memo-
    randa cannot be filed without the permission of the
    judicial authority.’’ The record here is clear that the
    defendants sought, and received, the court’s permission
    to file the surreply. After it considered the plaintiff’s
    objection, the court overruled the objection and granted
    the defendants permission to file the surreply.
    The judgment is affirmed.
    In this opinion the other judges concurred.
    1
    General Statutes § 45a-186 (a) requires the filing of an appeal in the
    Superior Court no later than thirty days after the mailing of the Probate
    Court’s decision. See Corneroli v. D’Amico, 
    116 Conn. App. 59
    , 67, 
    975 A.2d 107
    , cert. denied, 
    293 Conn. 928
    , 
    980 A.2d 909
     (2009).
    2
    Although, in his expert disclosure, the plaintiff represented that Attorney
    Berman would opine on the issue of causation, at his deposition, Attorney
    Berman was unable to do so. When asked if he had an opinion ‘‘as to whether
    it is more probable than not that the Superior Court would have decided
    in Mr. Corneroli’s favor,’’ Attorney Berman responded: ‘‘I do not have. That
    would be—I didn’t prepare for that answer or that question.’’ He further
    testified that he could not ‘‘answer whether or not [the plaintiff] would
    prevail.’’
    In its memorandum of decision, the court concluded that Attorney Ber-
    man’s testimony was ‘‘insufficient to establish a prima facie case on the
    issue of causation,’’ and noted his concessions ‘‘that he does not know and
    cannot predict whether [the Probate Court’s] decision would have been
    upheld or reversed on appeal,’’ and that he was ‘‘not prepared to opine as
    to whether it was more probable than not that the Superior Court would
    have found in Mr. Corneroli’s favor on appeal.’’ On appeal to this court, the
    plaintiff does not challenge the court’s conclusions as to Attorney Berman.
    Furthermore, the plaintiff’s counsel conceded during oral argument before
    this court that Attorney Berman only opined as to the applicable standard
    of care. Accordingly, we address the plaintiff’s claim only as it relates to
    the opinions of Professor McClane.
    3
    The plaintiff similarly argues that by rendering summary judgment in
    favor of the defendants, the trial court decided an issue of fact as to whether
    Professor McClane’s opinion as to causation was sufficient. This argument
    also is without merit, because as we have explained, to defeat summary
    judgment in his legal malpractice case, the plaintiff was required to present
    expert testimony on the essential element of causation. See Bozelko v.
    Papastavros, supra, 
    323 Conn. 284
    –85.
    4
    The plaintiff now contends that the trial court’s statement that ‘‘to decide
    contrary to the opinion of [the Probate Court], a Superior Court judge would
    certainly need a good reason,’’ indicates a misunderstanding of the nature
    of a de novo appeal from the Probate Court. Specifically, the plaintiff argues
    that since the appeal of a probate decision to the Superior Court ‘‘is not a
    challenge to the Probate Court’s decision’’ but, rather, is ‘‘a new action,’’ a
    plaintiff in a probate appeal to the Superior Court ‘‘has no duty to demon-
    strate any flaws in the Probate Court decision.’’ We do not understand the
    court’s statement to indicate a misunderstanding of the nature of a de novo
    appeal. The court’s statement merely recognizes that, to create a genuine
    issue of material fact to defeat summary judgment, the plaintiff’s expert
    must opine that the plaintiff more likely than not would have prevailed on
    appeal to the Superior Court, and explain the bases for that opinion. That
    necessarily would require Professor McClane to provide a ‘‘good reason’’
    as to why the Superior Court would ‘‘decide contrary to the opinion of [the
    Probate Court] . . . .’’
    Furthermore, the plaintiff did not request an articulation on this point,
    and ‘‘[t]o the extent that the [trial] court’s decision is ambiguous . . . it
    was [the appellant’s] responsibility to seek to have it clarified.’’ (Internal
    quotation marks omitted.) DiRienzo Mechanical Contractors, Inc. v. Salce

    , 169,

    , cert.
    denied, 
    298 Conn. 910
    , 
    4 A.3d 831
     (2010). ‘‘In the absence of a motion for
    articulation . . . it would be sheer speculation for this court to assume
    that the trial court applied the incorrect legal standard.’’ (Citation omitted;
    internal quotation marks omitted.) Daly v. DelPonte,

    ,

    225 Conn. 499
    , 
    624 A.2d 876
     (1993).
    5
    The plaintiff also argues that the trial court improperly found that an
    expert must employ the phrase ‘‘more likely than not’’ as to the issue of
    causation. The court, however, in its memorandum of decision, cited this
    court’s decision in Drew v. William W. Backus Hospital, supra, 
    77 Conn. App. 663
    , acknowledging that the sufficiency of an expert’s testimony does
    not depend on his use of any particular term or phrase. We, therefore, reject
    the factual premise of the plaintiff’s argument.
    6
    During his deposition, Professor McClane also opined that there was ‘‘a
    reasonable basis for a successful outcome of the appeal,’’ because there
    was ‘‘a reasonable basis that Corneroli would have been able to show that
    there was a partnership and that the painting was partnership property and
    that any disposition or any money coming out of a disposition of that painting
    was also partnership property . . . .’’ Professor McClane further testified
    that although he was aware that the Probate Court, for purposes of deciding
    the motion to disallow the claim against the decedent’s estate, assumed
    that a partnership did in fact exist between the plaintiff and the decedent,
    in his opinion, this assumption was ‘‘internally inconsistent’’ with some of
    the conclusions that the Probate Court reached in that decision. The plaintiff
    now argues that this testimony demonstrates Professor McClane’s opinion
    that it was reasonably probable that the plaintiff would have prevailed had
    the defendants filed a timely appeal. In light of our conclusion that Professor
    McClane did not have an adequate basis for his opinions, we need not
    address this argument.
    7
    The plaintiff also argues that the trial court: (1) improperly opined that
    the Probate Court’s decision was rational and logical ‘‘without any review
    or knowledge of evidence’’ presented during the probate proceedings; (2)
    improperly rendered summary judgment in favor of the defendants without
    any information regarding the evidence that would be presented at a de
    novo trial; and (3) failed to ‘‘contemplate’’ that new evidence, not presented
    to the Probate Court, may exist and be presented during a de novo trial to
    the Superior Court. We conclude that the plaintiff has abandoned these
    claims through inadequate briefing.
    ‘‘It is well settled that [w]e are not required to review claims that are
    inadequately briefed. . . . We consistently have held that [a]nalysis, rather
    than mere abstract assertion, is required in order to avoid abandoning an
    issue by failure to brief the issue properly. . . . [F]or this court judiciously
    and efficiently to consider claims of error raised on appeal . . . the parties
    must clearly and fully set forth their arguments in their briefs. We do not
    reverse the judgment of a trial court on the basis of challenges to its rulings
    that have not been adequately briefed. . . . The parties may not merely
    cite a legal principle without analyzing the relationship between the facts
    of the case and the law cited. . . . [A]ssignments of error which are merely
    mentioned but not briefed beyond a statement of the claim will be deemed
    abandoned and will not be reviewed by this court.’’ (Internal quotation
    marks omitted.) Benedetto v. Dietze & Associates, LLC, 
    159 Conn. App. 874
    ,

    , cert. denied, 
    320 Conn. 901
    , 
    127 A.3d 185
     (2015). The
    plaintiff has devoted just over a page of his brief to these three arguments,
    in which he does little more than briefly recite various factual assertions
    and one general principle of probate law. Accordingly, these claims are
    briefed inadequately, and we decline to review them.

    The plaintiff’s counsel at no time objected to the court’s consideration
    of the defendants’ reply brief, nor moved to strike the reply brief.

    Practice Book § 11-10 (c) provides: ‘‘Surreply memoranda cannot be filed
    without the permission of the judicial authority.’’

    In its memorandum of decision, the trial court refused to consider the
    affidavit. The court cited the decision of the United States Court of Appeals
    for the Second Circuit in Perma Research & Development Co. v. Singer Co.,
    
    410 F.2d 572
    , 578 (2d Cir. 1969), in which that court said: ‘‘If a party who
    has been examined at length on deposition could raise an issue of fact
    simply by submitting an affidavit contradicting his own prior testimony, this
    would greatly diminish the utility of summary judgment as a procedure for
    screening out sham issues of fact.’’ The trial court went on to conclude that,
    even if it were to ‘‘overlook the improbability of Professor McClane’s claim
    that when he was deposed, he did not understand what ‘more likely than
    not’ meant, neither his deposition testimony nor his affidavit provide any
    basis to support the opinion that Mr. Corneroli would probably have pre-
    vailed in his de novo probate appeal,’’ as Professor McClane testified that
    he was not familiar with the substance of the Probate Court’s opinion or
    the New York litigation vis-a`-vis the painting.
    The plaintiff now argues that the court erred by refusing to consider the
    affidavit. This claim warrants only a brief analysis. It is within the trial
    court’s discretion whether to accept or decline supplemental evidence in
    connection with a motion for summary judgment. Nieves v. Cirmo, 
    67 Conn. App. 576
    , 587 n.4, 
    787 A.2d 650
    , cert. denied, 
    259 Conn. 931
    , 
    793 A.2d 1085
    (2002). Although the court permitted the plaintiff to file a surreply for the
    purpose of responding to the defendants’ reply brief, the plaintiff went
    beyond merely responding to the defendants’ reply brief and attached an
    affidavit containing statements by Professor McClane, a witness that the
    defendants would not have the opportunity to redepose prior to the court’s
    decision on the motion for summary judgment. This court will not, on
    appeal, disturb the trial court’s discretion to refuse to consider supplemental
    evidence submitted after full briefing and argument on a motion for sum-
    mary judgment.
