    Opinion
    McDONALD, J. In 2007, the legislature adopted a
    paradigmatic shift in its approach to conservatorship
    appointments, including significant modifications to the
    circumstances and manner in which they may be made.
    This certified appeal requires us to consider how the
    substantive and procedural amendments to the conser-
    vatorship scheme set forth in No. 07-116 of the 2007
    Public Acts (P.A. 07-116) affected the Probate Court’s
    selection of a conservator in this case.
    The plaintiff, Sharon DeNunzio, appeals from the
    judgment of the Appellate Court affirming the trial
    court’s judgment which, in turn, affirmed the Probate
    Court’s decision to appoint the defendant, the plaintiff’s
    former husband, Peter DeNunzio, conservator of their
    adult son, Douglas DeNunzio.1 On appeal, the plaintiff
    claims that the Appellate Court improperly concluded
    that her substantial rights were not prejudiced because:
    (1) the Probate Court properly could use Douglas’ ‘‘best
    interests’’ as a consideration in the appointment of a
    conservator, in addition to the statutory factors adopted
    in P.A. 07-116; see General Statutes § 45a-650 (h);2 or
    as a guiding principle in applying those factors; and (2)
    a guardian ad litem’s report supporting the defendant’s
    appointment was properly considered by the Probate
    Court for its opinion as to the ultimate issue of fact and
    was not considered insofar as it contained inadmissible
    hearsay. We agree with the plaintiff that, after the enact-
    ment of P.A. 07-116, probate courts may no longer con-
    sider the amorphous ‘‘best interests’’ of a respondent
    in conservatorship proceedings. We further agree that
    probate courts may only consider evidence that has
    been properly admitted pursuant to the rules of evi-
    dence. We nevertheless conclude that, to the extent that
    the Probate Court may have engaged in such improper
    considerations, the plaintiff’s substantial rights were
    not prejudiced in light of the clear weight of the admissi-
    ble evidence supporting the defendant’s appointment
    under the proper standard. We therefore affirm the judg-
    ment of the Appellate Court.
    The record reveals the following undisputed facts
    and procedural history. For many years, Douglas has
    manifested symptoms of mental distress, including
    paranoia, extreme anxiety, and a tendency to persev-
    erate, meaning to obsess over a particular topic, most
    notably, his health. The plaintiff and the defendant,
    whose marriage was dissolved in 2003 when Douglas
    was still a minor, have been involved in a protracted
    dispute over whether Douglas’ symptoms were caused
    by chronic Lyme disease and/or psychological and/or
    developmental disorders. During the early stages of this
    dispute, the trial court in the dissolution action modified
    its custody orders to confer on the defendant sole deci-
    sion-making authority over medical decisions concern-
    ing Douglas. The trial court in the dissolution action
    subsequently held the plaintiff in contempt of that order
    after she took Douglas to a pediatrician without the
    defendant’s consent, finding that the plaintiff’s ‘‘preoc-
    cupation with Douglas’ health’’ was unhealthy for
    Douglas.
    Douglas’ numerous treating physicians have deter-
    mined that his symptoms were caused by schizophrenia
    and an Asperger spectrum disorder. The defendant
    accepted these physicians’ opinions and agreed with
    their advice to place Douglas on a regimen of antipsy-
    chotic medications, which appeared to them to stabilize
    Douglas’ condition. With the plaintiff’s consent, the
    defendant placed Douglas in a residential education
    and treatment facility (school) that holds itself out as
    specializing in the treatment of young males with devel-
    opmental, psychological and learning disorders. The
    school’s staff has concluded that Douglas was making
    good progress under this course of treatment.
    Although the plaintiff agrees that Douglas is on the
    autism spectrum, she disagrees with the defendant with
    respect to the cause of that condition and Douglas’
    symptoms of mental distress. Specifically, the plaintiff
    is convinced that these conditions have resulted from
    chronic Lyme disease that had persisted despite
    repeated courses of antibiotic treatment, negative test
    results, and Douglas’ ability to engage in vigorous ath-
    letic activities such as skiing. She therefore advocated
    substantially reducing Douglas’ antipsychotic medica-
    tion and treating him with antibiotics.
    In 2011, shortly after Douglas’ twenty-first birthday,
    the defendant filed an application in the Probate Court
    seeking to be appointed as Douglas’ conservator. The
    plaintiff filed an objection to that application, and filed
    an application seeking her own appointment. The Pro-
    bate Court thereafter appointed an attorney and a
    guardian ad litem for Douglas, Louise T. Truax and
    Richard J. Margenot, respectively.
    Because Douglas’ representatives and parents all stip-
    ulated that Douglas’ condition was such that he needed
    a conservator, the evidentiary hearing on the applica-
    tions focused principally on the question of who the
    conservator should be. Truax informed the court that
    Douglas had refused to express a preference regarding
    which one of his parents should be appointed. Both the
    plaintiff and the defendant testified at length regarding
    Douglas’ medical and educational history, and voiced
    their respective views about the underlying cause of
    his symptoms. The defendant also testified that he had
    taken Douglas to hundreds of medical appointments
    over the years, that he had discussed Douglas’ wishes
    regarding his medical treatment with Douglas as
    recently as the previous week, and that he was willing
    to commit his time and financial resources to ensure
    that Douglas received appropriate medical care. The
    plaintiff testified that Douglas wanted to be taken off
    of his current medication and treated for Lyme disease,
    that she would replace Douglas’ medical team if
    appointed, and that she believed that the defendant
    was not committed to following Douglas’ interests or
    promoting his independence.
    In support of his application, the defendant offered
    testimony from Douglas’ current treatment providers.
    These providers contrasted their observations of the
    defendant’s commitment to a course of treatment that
    had helped Douglas and Douglas’ calm state when under
    the defendant’s care with their contrary observations
    of the plaintiff. Nancy O’Hara, a physician who special-
    izes in autism and neurological development issues and
    who had treated Douglas for many years, testified that,
    although Douglas previously had Lyme disease, it had
    been effectively treated. O’Hara testified that the plain-
    tiff repeatedly had violated instructions not to discuss
    medical treatment with Douglas because it caused him
    severe anxiety. O’Hara also testified that she did not
    believe the plaintiff would adhere to her advice that
    Douglas should continue his antipsychotic medications.
    O’Hara further testified, over the plaintiff’s objection,
    that it was her opinion that the defendant, who had
    adhered to O’Hara’s instructions, should be appointed
    Douglas’ conservator. O’Hara’s concerns about the
    plaintiff’s conduct as it adversely effected Douglas’ state
    of mind was echoed in testimony from Shahrzad Yamini,
    a psychiatrist at Douglas’ school, and Joanne Boelke,
    a clinical therapist and social worker at the school.
    In support of the plaintiff’s application, the court
    heard testimony from two psychiatrists who had exam-
    ined Douglas eighteen months and three years prior to
    the hearing, respectively. In addition to their observa-
    tions based on those examinations, these experts
    offered opinions based on information that had been
    provided to them by the plaintiff. Carl Mueller testified
    that Douglas had an abnormality on the surface of his
    brain that could have been caused by chronic Lyme
    disease, and suggested the possibility that Douglas may
    be on too high a dosage of antipsychotic medication,
    but conceded that Douglas should continue the medica-
    tion as prescribed if the defendant accurately had repre-
    sented Douglas’ condition. Robert Bransfield opined
    that Lyme disease may be a contributory factor to Doug-
    las’ symptoms and therefore recommended that a Lyme
    disease specialist be added to Douglas’ treatment team
    and that the team consider adding antibiotics to Doug-
    las’ current medications.
    On the last day of the evidentiary hearings, Margenot
    filed a guardian ad litem report over the plaintiff’s objec-
    tion. The report indicated that Margenot had inter-
    viewed various medical and educational professionals,
    Douglas’ family members, and Douglas himself, and
    had reviewed various documents, including deposition
    testimony. The report stated that, based on this informa-
    tion and the evidence adduced during the preceding
    evidentiary hearings, Margenot’s opinion was that it
    was ‘‘in [Douglas’] best interests to appoint [the defen-
    dant] as [Douglas’] [c]onservator of the [p]erson and
    [e]state . . . .’’ The plaintiff claimed that the report
    was inadmissible because it contained hearsay and an
    opinion on the ultimate issue in the case. The Probate
    Court indicated that it believed that it was proper for
    a guardian ad litem to offer such an opinion, but with-
    held a definitive ruling on the admissibility of the report
    pending a review of the rules of evidence. Although
    Margenot did take the stand so that the plaintiff could
    question him regarding the report, it was never admitted
    into evidence.
    The Probate Court subsequently issued a decision
    finding by clear and convincing evidence that Douglas
    needed a conservator of both the person and estate and
    appointed the defendant as conservator. The Probate
    Court’s decision cited testimony related to Douglas’
    psychological and developmental conditions and symp-
    toms, the harmful effect that his parents’ conflict had
    on him, and concerns about the plaintiff’s interference
    with Douglas’ current course of medical treatment. The
    decision noted the filing of Margenot’s report and the
    conclusion therein that the defendant should be
    appointed conservator. The Probate Court concluded
    its decision by stating: ‘‘This court further finds that
    there is no doubt that both parents care and love their
    son deeply; that they cannot agree on the proper treat-
    ment for [Douglas] as they disagree with each other
    on [Douglas’] current diagnosis; that the [plaintiff’s]
    constant second-guessing of the professionals in charge
    of [Douglas’] care, causes inconsistent care, duress,
    anxiety and perseveration to [Douglas]; and that medi-
    cal professionals involved with [Douglas’] current care
    and supervision have testified that it is in the best
    interest of [Douglas] to have the [defendant] appointed
    as conservator. This court therefore appoints [the
    defendant] as the conservator of the person and estate
    of [Douglas] to serve without bond.’’ (Emphasis added.)
    The decision then set forth the conservator’s powers,
    followed by two statements simply noting, without elab-
    oration, that the court had considered the factors set
    forth in § 45a-650 (h) in deciding whom to appoint as
    conservator.
    The plaintiff appealed from the Probate Court’s deci-
    sion to the trial court pursuant to General Statutes
    § 45a-186. The plaintiff claimed, inter alia, that the Pro-
    bate Court had failed to apply the statutory factors for
    selecting a conservator set forth in § 45a-650 (h) and
    had improperly considered Margenot’s report. The trial
    court rejected these claims and affirmed the Probate
    Court’s decision. The trial court ultimately concluded
    that there was competent and compelling evidence that
    the appointment of the defendant rather than the plain-
    tiff was in Douglas’ best interests and that the plaintiff
    had not proved that her substantial rights were prej-
    udiced.
    The plaintiff appealed to the Appellate Court, reiterat-
    ing her claim that consideration of Margenot’s report
    was improper. In connection with that claim, the plain-
    tiff also asserted that the Probate Court’s decision
    improperly had been based on a standard that no longer
    existed following the enactment of P.A. 07-116. Specifi-
    cally, she contended that instead of applying the factors
    prescribed in § 45a-650 (h), the court improperly had
    applied the pre-2007 best interests of the conserved
    person standard.
    The Appellate Court affirmed the trial court’s judg-
    ment, concluding that the Probate Court’s decision had
    been rendered in conformity with the conservatorship
    scheme as modified by P.A. 07-116. DeNunzio v.
    DeNunzio, 
    151 Conn. App. 403
    , 
    95 A.3d 557
     (2014).
    With respect to Margenot’s report, the Appellate Court
    determined that, although the rules of evidence applied
    and Margenot’s report had not been admitted into evi-
    dence, the Probate Court had considered the report.
    
    Id., 412
    . Nonetheless, it concluded that Margenot could
    give his opinion on the ultimate issue of fact—who
    should be appointed as conservator—because having
    been appointed specifically to investigate the circum-
    stances of the parties, the specialized knowledge he
    had gained pursuant to his investigation qualified him
    to make recommendations to the court as to what
    appointment would be in Douglas’ best interests.3 
    Id.
    The Appellate Court further concluded that Margenot
    properly could rely on hearsay statements in reaching
    his opinion, and that there was no indication in the
    record that the Probate Court had relied on any hearsay
    in the report for substantive purposes in deciding to
    appoint the defendant. 
    Id., 414
    .
    In connection with its conclusion that the Probate
    Court could use the specialized knowledge acquired by
    Margenot to assist it with its determination as to what
    appointment would be in Douglas’ best interests, the
    Appellate Court stated: ‘‘To the extent that the plaintiff
    suggests that the court is confined to the factors set
    forth in § 45a-650 (h) in determining whom to appoint
    as conservator, and the best interests of the conservatee
    are not a consideration, we disagree. The statutory fac-
    tors cannot be considered in a vacuum. Consistent with
    the overall policy and purpose of a conservatorship,
    the best interests of a conservatee must always be a
    consideration and a guide in examining the statutory
    factors. In other words, because a conservator is
    appointed to serve the best interests of the conservatee,
    the statutory factors enumerated in § 45a-650 (h) must
    be considered with the overarching purpose of serving
    those interests.’’ Id., 409 n.3.
    We subsequently granted the plaintiff’s petition for
    certification to appeal, limited to the following issues:
    (1) ‘‘Did the Appellate Court properly conclude that the
    [Probate Court properly could use] the ‘best interest[s]
    of the conservatee’ standard as [a consideration and a
    guide in examining the statutory factors]?’’; and (2) ‘‘Did
    the Appellate Court properly determine that . . . the
    plaintiff’s substanti[al] rights were not prejudiced by
    the Probate Court’s consideration of . . . Margenot’s
    report, which was not admitted into evidence?’’4
    DeNunzio v. DeNunzio, 
    314 Conn. 926
    , 
    101 A.3d 271
    (2014). We conclude that the statutory factors adopted
    by the legislature in § 16 of P.A. 07-116 and codified
    as § 45a-650 (h) wholly supplant any ‘‘best interests’’
    consideration, but, to the extent that the Probate Court
    considered that matter, the record demonstrates that
    the statutory factors were considered and supported
    the Probate Court’s selection of the defendant as con-
    servator. We further conclude that, although there
    appears to be clear tension between a guardian ad
    litem’s report being considered for substantive pur-
    poses without being admitted into evidence and the
    strict procedural changes mandated under P.A. 07-116,
    we are not persuaded that any improper reliance on
    Margenot’s report would have affected the outcome.
    Accordingly, the plaintiff’s substantial rights were not
    prejudiced.
    Before turning to the merits of the plaintiff’s claim,
    it is useful to set forth a brief overview of the relevant
    2007 amendments to the conservatorship process, and
    the legal context in which those changes were adopted.
    See P.A. 07-116. Prior to 2007, this court generally
    adhered to the principle that ‘‘the legal disability of an
    incompetent is analogous to that of a minor.’’ Cottrell
    v. Connecticut Bank & Trust Co., 
    175 Conn. 257
    , 264,
    
    398 A.2d 307
     (1978); accord Lesnewski v. Redvers, 
    276 Conn. 526
    , 537, 
    886 A.2d 1207
     (2005), overruled by Gross
    v. Rell, 
    304 Conn. 234
    , 270–71, 
    40 A.3d 240
     (2012).5 This
    court thus reasoned that ‘‘there is no difference in the
    court’s duty to safeguard the interests of a minor and
    the interests of a conserved person. . . . This is
    reflected in the statutory scheme governing conserva-
    torships, which requires the Probate Court to be guided
    by the conserved person’s best interests in establishing
    the conservatorship and selecting the conservator; Gen-
    eral Statutes [Rev. to 2005] § 45a-650 (e); limiting the
    conservator’s powers and duties; General Statutes [Rev.
    to 2005] § 45a-650 (h); resolving conflicts between con-
    servators; General Statutes [Rev. to 2005] § 45a-657;
    approving a conservator’s petition to sell or mortgage
    the conserved person’s real property; General Statutes
    [Rev. to 2005] § 45a-164 (a); and determining whether
    to remove a conservator. General Statutes [Rev. to 2005]
    §§ 45a-242 (a) and 45a-199 . . . .’’6 (Citations omitted.)
    Lesnewski v. Redvers, 
    supra,
     540–41.
    Public Act 07-116 evidenced a fundamental shift in
    policy regarding the capacity of conserved persons and
    their concomitant rights. As our courts previously have
    recognized, the legislature made comprehensive sub-
    stantive and procedural changes to the conservatorship
    scheme designed to require probate courts to respect
    individuals’ preferences, impose the least restrictive
    means of intervention, and provide more transparency
    and accountability in the conservatorship process. See
    Kortner v. Martise, 
    312 Conn. 1
    , 53–56, 
    91 A.3d 412
    (2014) (discussing legislative history of P.A. 07-116);
    Falvey v. Zurolo, 
    130 Conn. App. 243
    , 250–53, 
    22 A.3d 682
     (2011) (same). These changes included enumerat-
    ing factors that must be considered in determining
    whether a conservator is necessary and, if one is neces-
    sary, who should be appointed as conservator. P.A. 07-
    116, § 16 (codified as § 45a-650 [g] and [h]).
    Public Act 07-116, § 16, also required the Probate
    Court to follow more formal procedures, under which
    the rules of evidence for civil proceedings apply and
    testimony is taken under oath. Proceedings relating to
    the selection of a conservator are required to be con-
    ducted on the record; General Statutes § 45a-650 (b);
    eliminating the usual practice prior to 2007, under
    which appeals from decisions rendered by the Probate
    Court were trials de novo. General Statutes (Rev. to
    2007) § 45a-186 (a); see P.A. 07-116, § 2 (amending § 45a-
    186 [a]); Lesnewski v. Redvers, 
    supra,
     
    276 Conn. 543
    .
    Because of the formalities required in such proceedings,
    they are subject to a new standard of review, under
    which ‘‘[t]he Superior Court shall affirm the decision
    of the Court of Probate unless the Superior Court finds
    that substantial rights of the person appealing have
    been prejudiced because the findings, inferences, con-
    clusions or decisions are: (1) In violation of the federal
    or state constitution or the general statutes, (2) in
    excess of the statutory authority of the Court of Pro-
    bate, (3) made on unlawful procedure, (4) affected by
    other error of law, (5) clearly erroneous in view of
    the reliable, probative and substantial evidence on the
    whole record, or (6) arbitrary or capricious or charac-
    terized by abuse of discretion or clearly unwarranted
    exercise of discretion.’’ General Statutes § 45a-186b; see
    also Falvey v. Zurolo, supra, 
    130 Conn. App. 256
    –57
    (explaining that this standard also applies to appel-
    late courts).
    I
    With that background in mind, we turn to the plain-
    tiff’s claim that the Appellate Court improperly con-
    cluded that the Probate Court could consider the ‘‘best
    interests’’ of the respondent in selecting a conservator,
    either as an independent consideration or an overarch-
    ing guiding principle. The plaintiff contends that,
    because the ‘‘best interests’’ standard was excised from
    the relevant statute and replaced with five mandatory
    factors to be considered, it would be inconsistent with
    the statutory text and the purpose of P.A. 07-116 in
    limiting the probate courts’ discretion to allow the Pro-
    bate Court to use the respondent’s ‘‘best interests’’ in
    selecting a conservator. The plaintiff further contends
    that the decision evidences that the Probate Court made
    its decision on the basis of which appointment would
    be in Douglas’ best interests by reciting opinion testi-
    mony to that effect and by failing to make any findings
    relating to the statutory factors. In response, the defen-
    dant contends that the decision indicates that the Pro-
    bate Court’s decision was predicated on the statutory
    factors, but even if the court did consider Douglas’ best
    interests, P.A. 07-116 did not intend to preclude such
    a consideration.7 The defendant notes that other sec-
    tions of the conservatorship statutes expressly retain
    the ‘‘best interests’’ standard. See, e.g., General Statutes
    §§ 45a-132 (d) and 45a-657. We conclude that the
    respondent’s ‘‘best interests’’ are neither a factor nor
    an overarching guide in selecting a conservator. We
    further conclude, however, that to the extent that the
    Probate Court considered Douglas’ best interests, that
    consideration was not harmful given the Probate
    Court’s consideration of the statutory factors and the
    clear weight of the admissible evidence supporting its
    decision under those factors.8
    A
    The question of whether the ‘‘best interests’’ standard
    is a proper consideration or guide to selecting a conser-
    vator is a matter of law, subject to plenary review and
    our well established principles of statutory construc-
    tion. See General Statutes § 1-2z (setting forth plain
    meaning rule); Teresa T. v. Ragaglia, 
    272 Conn. 734
    ,
    742, 
    865 A.2d 428
     (2005) (‘‘[w]hen a statute is not plain
    and unambiguous, we also seek interpretive guidance
    from the legislative history of the statute and the cir-
    cumstances surrounding its enactment, the legislative
    policy it was designed to implement, the statute’s rela-
    tionship to existing legislation and common-law princi-
    ples governing the same general subject matter’’).
    As previously noted, § 16 of P.A. 07-116 amended
    § 45a-650, which prescribes the procedures a Probate
    Court must follow in determining whether to appoint
    a conservator on an application for involuntary repre-
    sentation and, if so, who should be appointed to serve
    that role. Prior to the passage of P.A. 07-116, the statute
    provided that ‘‘the court shall be guided by the best
    interests of the respondent’’ in making both determina-
    tions. General Statutes (Rev. to 2007) § 45a-650 (e).
    Indeed, even when the respondent had requested that
    a particular person serve as conservator, the Probate
    Court could disregard that choice if it found that the
    respondent lacked ‘‘sufficient capacity to form an intel-
    ligent preference’’ or if that appointment was ‘‘not in
    the best interests of the respondent.’’ General Statutes
    (Rev. to 2007) § 45a-650 (e). Public Act 07-116, § 16,
    deleted the intelligent preference requirement and
    every reference to ‘‘best interests’’ in § 45a-650. Instead,
    it directed the Probate Court to comply with the respon-
    dent’s choice unless the nominee was unwilling, unable,
    or disqualified by substantial evidence. P.A. 07-116, § 16.
    In the absence of an expressed choice, P.A. 07-116 pre-
    scribed as follows: ‘‘In considering who to appoint . . .
    the court shall consider (1) the extent to which a pro-
    posed conservator has knowledge of the respondent’s
    or conserved person’s preferences regarding the care
    of his or her person or the management of his or her
    affairs, (2) the ability of the proposed conservator to
    carry out the duties, responsibilities and powers of a
    conservator, (3) the cost of the proposed conservator-
    ship to the estate of the respondent or conserved per-
    son, (4) the proposed conservator’s commitment to
    promoting the respondent’s or conserved person’s wel-
    fare and independence, and (5) any existing or potential
    conflicts of interest of the proposed conservator.’’ P.A.
    07-116, § 16, codified as § 45a-650 (h).
    In light of this background, we can readily dispense
    with the Appellate Court’s determination that the
    respondent’s best interests may be considered as a fac-
    tor in conjunction with the statutory factors. Under the
    doctrine of expressio unius est exclusio alterius—the
    expression of one thing is the exclusion of another—
    we presume that when the legislature expresses items
    as part of a group or series, an item that was not
    included was deliberately excluded. State v. Bell, 
    303 Conn. 246
    , 265, 
    33 A.3d 167
     (2011). Indeed, because the
    legislature affirmatively deleted every reference to best
    interests in § 45a-650, we presume that the legislature
    intended to remove that matter from consideration.
    This presumption is reinforced by the fact that the legis-
    lature undoubtedly knows how to enumerate a nonex-
    clusive list of factors when it wants to. See, e.g., General
    Statutes § 19a-528 (‘‘the commissioner may consider all
    factors that the commissioner deems relevant, includ-
    ing, but not limited to, the following’’); General Statutes
    § 51-219b (a) (‘‘the following factors, as well as any
    other factors which may be relevant, shall be consid-
    ered’’). Using best interests as a factor could thwart
    the legislature’s clear intent because nothing would pre-
    clude the Probate Court from giving that factor disposi-
    tive weight after considering the statutory factors.
    We similarly are not persuaded that the respondent’s
    ‘‘best interests’’ remain an overarching guide through
    which the statutory factors should be analyzed. That
    contention is at odds with the text and purposes of P.A.
    07-116. The legislature readily could have retained the
    language directing that the Probate Court ‘‘shall be
    guided by the best interests of the respondent’’; General
    Statutes (Rev. to 2007) § 45a-650 (e); in selecting a con-
    servator and simply elaborated that the statutory fac-
    tors were relevant to that assessment. Instead, the
    legislature unambiguously chose to excise the phrase
    ‘‘shall be guided by the best interests of the respondent’’
    from § 45a-650. Indeed, the fact that the legislature
    retained the ‘‘best interests’’ standard in a few other
    sections of the conservatorship scheme demonstrates
    that it retained that standard where it intended for that
    standard to apply. It is noteworthy that the provisions
    in which the ‘‘best interests’’ standard was retained all
    involve issues that arise after a conservator has been
    appointed and been provided with those limited powers
    that cannot be retained by the conservatee. See, e.g.,
    General Statutes § 45a-164 (a) (sale or mortgage of real
    property); General Statutes § 45a-655 (e) (distribution
    of gifts from estate); General Statutes § 45a-657 (con-
    flicts between conservators); General Statutes § 45a-
    679 (conflicts between guardians and conservators).
    The text of P.A. 07-116 therefore indicates that the legis-
    lature retained the ‘‘best interests’’ standard in the spe-
    cific circumstances in which it was appropriate and
    abandoned it in those for which it was not.
    Although we acknowledge that faithful application
    of the enumerated factors should yield a result that is in
    a respondent’s best interests, as that term is commonly
    understood, the legislature evidently recognized that
    the ‘‘best interests’’ standard has historically been
    imbued with a particular meaning in Probate Court
    proceedings—one that effectively equates adults who
    are respondents in conservation proceedings with
    minors. Public Act 07-116 unambiguously manifests that
    such a paternalistic view no longer is consistent with
    a contemporary understanding of the broad range of
    capacities of persons who are in need of a conservator
    and the necessity of preserving the rights of such per-
    sons to the greatest extent possible. See, e.g., P.A. 07-
    116, § 1 (allowing respondent or conserved person to
    refuse court-ordered examination by physician, psychi-
    atrist or psychologist); P.A. 07-116, § 16 (requiring con-
    servators, in carrying out their duties, to employ least
    restrictive means necessary to meet needs of conserved
    person and reserving to conserved person all rights
    and authority not expressly assigned to conservator).
    Indeed, because there is no statute or rule that expressly
    directs the Probate Court to make findings on the record
    in support of the enumerated factors; cf. Practice Book
    § 6-1 (requiring trial court to state basis for conclusion
    as to each claim of law and factual basis therefor in
    rulings that constitute final judgment for purposes of
    appeal); sanctioning the Probate Court’s use of the
    respondent’s best interests as a ‘‘guide’’ in considering
    those factors runs the risk of the Probate Court effec-
    tively continuing to follow past practice. Doing so obvi-
    ously would be at odds with the goal of P.A. 07-116 to
    ensure greater accountability in the conservatorship
    process. We therefore conclude that the ‘‘best interests’’
    of the respondent are neither a factor nor a guide in
    the selection of a conservator.
    B
    Having concluded that the ‘‘best interests’’ of the
    respondent are no longer a proper consideration in
    making such an appointment, we must determine
    whether the Probate Court improperly engaged in such
    a consideration, and, if so, whether the plaintiff’s sub-
    stantial rights were prejudiced by any such impropriety.
    Although it appears that the Probate Court considered
    Douglas’ best interests, we conclude that this impropri-
    ety was not harmful because the record reflects that the
    Probate Court ultimately, but imperfectly, predicated its
    decision on the statutory factors.
    We note at the outset that the Probate Court’s deci-
    sion is not a model of clarity. The Probate Court unam-
    biguously stated twice in its decision that it had
    considered the factors set forth in § 45a-650 (h) in
    selecting the defendant.9 The decision does not, how-
    ever, reference any of the specific statutory factors or
    state factual findings that are directly connected to any
    one of those factors. In what appears to be a brief
    summary of the evidence preceding the decision to
    appoint the defendant, much of the evidence recited is
    more directly related to why the plaintiff is not qualified
    or the better qualified person to be the conservator
    rather than why the defendant is qualified or the better
    qualified person. In the court’s statements immediately
    preceding its statement appointing the defendant, the
    court noted ‘‘that medical professionals involved with
    [Douglas’] current care and supervision have testified
    that it is the best interest[s] of [Douglas] to have the
    [defendant] appointed as [c]onservator.’’
    When examining an ambiguous decision, however,
    ‘‘we presume that the trial court applied the correct
    standard . . . .’’ Singhaviroj v. Board of Education,
    
    301 Conn. 1
    , 17 n.12, 
    17 A.3d 1013
     (2011). We also ‘‘read
    the record to support, rather than to undermine, the
    judgment.’’ (Internal quotation marks omitted.)
    Blumenthal v. Kimber Mfg., Inc., 
    265 Conn. 1
    , 9, 
    826 A.2d 1088
     (2003).
    The record lends strong support to the statements
    in the decision that the Probate Court considered, and
    in fact relied on, the statutory factors. It is clear that
    the parties litigated the case under the expectation that
    the statutory factors would govern the court’s decision.
    The defendant’s attorney asked various witnesses ques-
    tions relating to those factors. The attorney asked
    Yamini, for example, whether, in her opinion, the defen-
    dant had ‘‘any personal conflicts’’ with any of Douglas’
    physicians, whether he had ‘‘the ability to carry out
    the duties and responsibilities’’ of a conservator, and
    whether he had knowledge of Douglas’ preferences.
    Although O’Hara used the term ‘‘best interest’’ on a
    few occasions during her testimony, including when
    expressing her belief that both parents had Douglas’
    ‘‘best interest’’ at heart, none of the questions posed to
    her sought to elicit an opinion in terms of Douglas’
    best interests. Indeed, the plaintiff did not object to the
    relevancy of those questions posed or the responses
    given thereto. The plaintiff and the defendant also
    focused on the statutory factors in their closing argu-
    ments. The defendant’s attorney, for example, stated
    ‘‘[l]et’s discuss the statutory factors Your Honor needs
    to consider,’’ and then went through the factors one by
    one. The plaintiff’s attorney responded, arguing why
    the factors weighed in favor of appointing the plaintiff.
    Given this posture, we are not persuaded that the Pro-
    bate Court either ignored this evidence and argument
    while stating in its decision that these factors were
    considered, or decided, without notice to the parties,
    that a factor other than the statutory factors would be
    given conclusive weight.
    We acknowledge, however, that on the last day of
    the evidentiary hearings, the Probate Court stated that
    it had ‘‘to determine . . . what [was] in the best inter-
    est of’’ Douglas. In light of the Probate Court’s decision
    and the litigation posture of the parties, however, it
    appears most likely that the Probate Court unwisely
    used the phrase ‘‘best interest’’ as shorthand for the
    collective effect of the statutory factors. Indeed, in its
    decision, the court stated that Douglas’ current treat-
    ment providers had testified that it would be in Douglas’
    best interest to have the defendant appointed as conser-
    vator. Only O’Hara, however, had made a statement to
    that effect; the other providers directed their testimony
    to the statutory factors. Therefore, we conclude that,
    even assuming Douglas’ ‘‘best interests’’ were consid-
    ered, the plaintiff has failed to demonstrate that her
    substantial rights were prejudiced.
    We underscore, however, that, had the record not
    been so clear that this case was litigated under the
    statutory factors, we would have been compelled to
    request an articulation or reverse the judgment. See,
    e.g., Falvey v. Zurolo, supra, 
    130 Conn. App. 255
     (con-
    cluding that appointment of defendant as conservator
    was arbitrary and constituted abuse of discretion when
    Probate Court indicated that it had considered § 45a-
    650 [h] factors in appointing defendant but ‘‘the record
    [was] bereft of any evidence regarding the defendant
    or his qualifications to be conservator’’). Moreover,
    although we recognize that there is no rule of practice
    or statute expressly requiring the Probate Court to make
    specific findings relating to the court’s consideration
    of each of the statutory factors, it clearly would be the
    better practice to do so.
    II
    We now turn to the plaintiff’s claim that her substan-
    tial rights were prejudiced by the Probate Court’s con-
    sideration of Margenot’s report. Although Margenot’s
    report was never offered or admitted as evidence, the
    plaintiff claims that the Probate Court improperly relied
    on it as though it had been, when the report could not
    have been properly received into evidence because: (1)
    it contained a conclusion on the ultimate issue insofar
    as it recommended that the defendant be appointed;
    and (2) it was replete with hearsay. With respect to the
    first reason, the plaintiff argues that no one can be an
    expert qualified to testify on the ultimate issue of who
    should be appointed as a conservator because the § 45a-
    650 (h) factors ‘‘present questions of fact [that] do not
    require any special scientific or technical knowledge
    to decide.’’10 Thus, according to the plaintiff, a recom-
    mendation on who should be appointed as conservator
    is not necessary to assist the court, and is therefore
    inadmissible under the rules of evidence. In the alterna-
    tive, the plaintiff argues that, even if an expert’s recom-
    mendation could help the court, a guardian ad litem
    may be an expert on the law, if also an attorney, but
    is not an expert on disabled adults. With respect to
    her second reason, the plaintiff claims that the hearsay
    throughout the report was harmful, pointing specifically
    to a statement attributed to O’Hara that the plaintiff’s
    appointment as conservator would ‘‘ ‘kill’ ’’ Douglas.
    The defendant responds that there is no evidence that
    the Probate Court relied on the report, and, even if the
    court did rely on it, the report was cumulative of other
    admissible evidence and therefore harmless. We con-
    clude that consideration of the report would have been
    improper under the circumstances. Nonetheless, we are
    not persuaded that the report, to the extent that it may
    have been considered, had a substantial impact on the
    Probate Court’s decision.
    One of the fundamental reasons that, prior to 2007,
    appeals from conservatorship proceedings were subject
    to trials de novo in the trial court was because Probate
    Court proceedings were relatively informal. See
    Thomas v. Arafeh, 
    174 Conn. 464
    , 470, 
    391 A.2d 133
    (1978) (noting, inter alia, that strict rules of evidence
    were rarely followed). The trial court in the present
    case, however, was bound to follow the rules of evi-
    dence. See Conn. Code Evid. § 1-1 (b). Following the
    enactment of P.A. 07-116, in conservatorship proceed-
    ings under § 45a-650, the Probate Court is required to
    adhere to the more formalized procedures to which the
    trial court previously was bound. See General Statutes
    § 45a-650 (b). Thus, statements in a report by a guardian
    ad litem cannot be relied on as substantive evidence
    unless the report has been properly admitted into
    evidence.
    A guardian ad litem’s report is, by its nature, hearsay
    if offered for its truth, and it typically contains hearsay
    within hearsay insofar as it contains the out-of-court
    statements of others. See Conn. Code Evid. § 8-1 (defin-
    ing hearsay). Use of such statements for substantive
    purposes (i.e., their truth) is barred unless they satisfy
    an exception provided by a statute or rule. See Conn.
    Code Evid. §§ 8-2 and 8-7. Such statements may be used,
    however, for nonsubstantive purposes under certain
    conditions. See, e.g., Conn. Code Evid. § 7-4 (b) (‘‘The
    facts in the particular case upon which an expert bases
    an opinion . . . need not be admissible in evidence if
    of a type customarily relied on by experts in the particu-
    lar field in forming opinions on the subject. The facts
    relied on pursuant to this subsection are not substantive
    evidence, unless otherwise admissible as such evi-
    dence.’’). An opinion on an ultimate issue of fact may
    likewise be inadmissible unless certain predicates are
    satisfied. See Conn. Code Evid. §§ 7-2, 7-3 and 7-4. In
    addition to these evidentiary constraints, relying on
    such a report for substantive purposes without requir-
    ing its author to be subject to cross-examination may
    raise due process concerns. See Toms v. Toms, 
    98 S.W.3d 140
    , 144–45 (Tenn. 2003).
    During the proceedings in the present case, however,
    a Probate Court rule was in effect requiring a guardian
    ad litem to submit a written report to the court. Probate
    Court Rules (2012) § 4.3. Although that rule since has
    been repealed; see Probate Court Rules § 13.6 (effective
    July 1, 2013); a recent amendment to the conservator-
    ship scheme appears to sanction or at least acknowl-
    edge the practice of guardians ad litem submitting
    reports to the court. See Public Acts 2012, No. 12-25,
    § 1, codified as General Statutes § 45a-132 (a) (3) (‘‘[a]ny
    appointment of a guardian ad litem under this subdivi-
    sion shall terminate upon the guardian ad litem’s report
    to the judge or magistrate . . . or earlier upon the
    order of the judge or magistrate’’).11 Nonetheless, the
    legislature has not set forth an exception to the eviden-
    tiary requirements for guardian ad litem reports. Cf.
    General Statutes § 54-46a (b) (in probable cause hear-
    ings, ‘‘[t]he court shall be confined to the rules of evi-
    dence, except that written reports of expert witnesses
    shall be admissible in evidence and matters involving
    chain of custody shall be exempt from such rules’’). It
    may be, however, that these reporting practices can be
    reconciled with the mandate that the rules of evidence
    apply to conservatorship proceedings.
    Some courts have also drawn a distinction between
    reliance on such reports for substantive purposes and
    review for nonsubstantive purposes. See, e.g., Toms v.
    Toms, 
    supra,
     
    98 S.W.3d 144
     (‘‘[a]lthough a guardian ad
    litem’s report is not admissible evidence, we hold that
    such a report may be reviewed by a trial court’’); Joyce
    S. v. Frank S., 
    6 Neb. App. 23
    , 33, 
    571 N.W.2d 801
     (1997)
    (distinguishing between reviewing report to determine
    whether guardian ad litem has performed adequate
    investigation and relying on it for truth of statements
    therein). Indeed, the Tennessee Supreme Court noted
    that holding otherwise and precluding the submission
    of reports ‘‘would effectively undermine the important
    role played by a guardian ad litem’’ and that a guardian
    ad litem’s report ‘‘may assist the parties by: [1] alerting
    the parties to the identity of potential witnesses who
    may be interviewed; [2] highlighting the testimony, both
    favorable and unfavorable, that may be presented at
    trial; and [3] providing a third party’s view of the facts
    of the case.’’ Toms v. Toms, 
    supra, 144
    .
    In the present case, it is not clear to this court that
    the Probate Court relied on the report for substantive
    purposes rather than simply acknowledged that it had
    reviewed the report because it was required under then
    existing court rules to accept it. We first observe that
    every paragraph in the Probate Court’s decision, except
    the one relating to the report, commenced with the
    phrase ‘‘This court finds’’ or ‘‘This court further finds
    . . . .’’ In contrast, the decision states: ‘‘Margenot,
    guardian ad litem, has filed his report . . . .’’ This
    appears to be a purposeful distinction. We further
    observe that the court never resolved on the record the
    plaintiff’s specific evidentiary objections to the report
    or otherwise suggested why it had concluded that it
    could rely on the report in light of the statutory require-
    ment of compliance with the rules of evidence that had
    been brought to the court’s attention. With respect to
    any hearsay on which Margenot relied in reaching his
    recommendations, we agree with the trial court and
    the Appellate Court that there is no indication in the
    record that the Probate Court relied on any such hear-
    say for substantive purposes. With respect to
    Margenot’s opinion as to the ultimate issue of fact,
    even if we assume that this opinion was substantively
    considered, we are not persuaded that any such impro-
    priety prejudiced the plaintiff’s substantial rights.
    ‘‘When a court commits an evidentiary impropriety,
    we will reverse the trial court’s judgment only if we
    conclude that the trial court’s improper ruling harmed
    [a party]. . . . In a civil case, a party proves harm by
    showing that the improper evidentiary ruling likely
    affected the outcome of the proceeding.’’ (Citation omit-
    ted.) Weaver v. McKnight, 
    313 Conn. 393
    , 417, 
    97 A.3d 920
     (2014). ‘‘It is well established that if erroneously
    admitted evidence is merely cumulative of other evi-
    dence presented in the case, its admission does not
    constitute reversible error.’’ Swenson v. Sawoska, 
    215 Conn. 148
    , 155, 
    575 A.2d 206
     (1990). ‘‘In determining
    whether evidence is merely cumulative, we consider
    the nature of the evidence and whether any other evi-
    dence was admitted that was probative of the same
    issue as the evidence in controversy.’’ Duncan v. Mill
    Management Co. of Greenwich, Inc., 
    308 Conn. 1
    , 23,
    
    60 A.3d 222
     (2013).
    The critical dispute before the Probate Court was
    which parent was committed to a course of treatment
    that would promote Douglas’ welfare and indepen-
    dence. The defendant marshaled testimony from all of
    Douglas’ current treatment providers in support of his
    application. Most significantly, O’Hara, who had treated
    Douglas for many years, had undertaken extensive test-
    ing and examinations of him, and who specialized in
    the very conditions at issue, opined that the defendant
    was pursuing the proper and effective course of treat-
    ment. The plaintiff’s own experts offered some support
    for the course of treatment undertaken by the defendant
    and only supported the possibility that Douglas could
    still have Lyme disease and that such a condition could
    be a contributing factor in his condition. Therefore, we
    cannot conclude that Margenot’s opinion, which was
    consistent with the view of Douglas’ longtime treating
    physician and the clear weight of the remaining evi-
    dence, likely affected the outcome.
    The judgment of the Appellate Court is affirmed.
    In this opinion the other justices concurred.
    1
    In her complaint appealing from the Probate Court’s decision, the plaintiff
    named Peter DeNunzio and Douglas DeNunzio as defendants. For conve-
    nience, we refer to Peter DeNunzio as the defendant and to Douglas DeNun-
    zio by his first name.
    2
    Although § 45a-650 has been amended by the legislature since the events
    underlying the present case; see, e.g., Public Acts 2014, No. 14-103, § 6; those
    amendments have no bearing on the merits of this appeal. In the interest
    of simplicity, we refer to the current revision of the statute.
    3
    The Appellate Court’s opinion principally focused on a statement made
    in the Probate Court by Margenot at oral argument on the admissibility of
    his report regarding his opinion as to who should serve as conservator;
    DeNunzio v. DeNunzio, supra, 
    151 Conn. App. 410
    –11; but the Appellate
    Court noted that the same reasoning applies to his opinion in the report.
    
    Id.,
     412 n.6.

    The first question, as certified, stated: ‘‘Did the Appellate Court properly
    conclude that the trial court correctly used the ‘best interest of the conser-
    vatee’ standard as the basis for its decision?’’ DeNunzio v. DeNunzio, 
    314 Conn. 926
    , 
    101 A.3d 271
     (2014). In accordance with established practice,
    we have reframed the question to more accurately reflect the issue presented
    to the Appellate Court. See State v. Ouellette, 
    295 Conn. 173
    , 184, 
    989 A.2d 1048
     (2010).
    5
    In Gross v. Rell, supra, 
    304 Conn. 269
    , this court recognized that, even
    under the pre-2007 scheme, the legal status of incapable adults was not
    equivalent to minors for all purposes. In that case, this court concluded that
    ‘‘the governing standard for the representation of impaired adult clients is
    not the protection of their best interests, but, to the extent possible, the
    zealous advocacy of their expressed preferences. This is true even if the
    Probate Court has appointed a conservator for the client.’’ Id.; see id., 264,
    270–71 (citing 2005 revision to General Statutes as applicable to case before
    court and overruling Lesnewski v. Redvers, 
    supra,
     
    276 Conn. 526
    , insofar
    as it held that conserved person may appeal in his or her own name from
    Probate Court decision only if conserved person’s attorney demonstrates
    to trial court that appeal is in conserved person’s best interests).

    Recently, in Kortner v. Martise, 
    312 Conn. 1
    , 52–53, 
    91 A.3d 412
     (2014),
    this court quoted this best interests framework from Lesnewski v. Redvers,
    
    supra,

    –41, under circumstances that did not require us to
    consider whether the ‘‘best interests’’ standard continued to apply to the
    selection of the conservator following the enactment of P.A. 07-116. Because
    Kortner was decided well after the Probate Court’s decision in the present
    case, it could not have influenced that court’s view of the proper legal
    standard. Nonetheless, it may have influenced the Appellate Court’s view
    of the law, which we now clarify.

    Truax filed a brief in this court on behalf of Douglas arguing against
    the position advanced by the plaintiff in this certified appeal. The plaintiff
    contends that we should not consider Truax’ brief because the fact that
    Douglas did not want to take a position before the Probate Court on which
    one of his parents should serve as his conservator makes it unethical for
    Truax to advocate for one parent over the other on appeal. Because Truax’
    brief does not raise any arguments that substantively differ from the defen-
    dant’s, however, we need not consider the plaintiff’s contention.

    We do not rely on Margenot’s report in reaching that conclusion. See
    part II of this opinion.

    The fact that one statement in the decision refers to the ‘‘conservator(s)
    named above,’’ rather than the ‘‘conservator’’ raises a question as to whether
    this statement was preprinted on the Probate Court form. Nonetheless, the
    plaintiff has neither advanced such a contention, nor provided this court
    with a copy of the Probate Court form then in effect.

    It is unclear from the plaintiff’s argument whether she recognizes that
    an expert may not only have scientific or technical knowledge, but also
    may have ‘‘other specialized knowledge’’ for which he or she is qualified as
    an expert by skill, experience, training, or education. See Conn. Code Evid.
    § 7-2.

    We recognize that there is an inherent tension between the guardian
    ad litem’s traditional role as an advocate for the respondent’s ‘‘best interests’’
    and his or her role in proceedings determining whether a conservator is
    necessary and who should be appointed in light of the fact that the ‘‘best
    interests’’ standard no longer is applicable to such proceedings. The 2012
    amendment to the conservatorship statutes, however, limited the circum-
    stances under which a guardian ad litem may be appointed in conservator-
    ship proceedings and required the order making such an appointment to
    specifically delineate the scope of the guardian ad litem’s mandate. See
    General Statutes § 45a-132 (a) (3) (‘‘No judge or magistrate may appoint a
    guardian ad litem for a conserved person in a proceeding under section
    17a-543 or 17a-543a or sections 45a-644 to 45a-663, inclusive, unless [A] the
    judge or magistrate makes a specific finding of a need to appoint a guardian
    ad litem for a specific purpose or to answer specific questions to assist the
    judge or magistrate in making a determination, or [B] the conserved person’s
    attorney is unable to ascertain the preferences of the person, including
    preferences previously expressed by the person. Prior to appointing a guard-
    ian ad litem for a person under subparagraph [B] of this subdivision, the
    judge or magistrate may question the person to determine the person’s
    preferences or inability to express such preferences. If the judge or magis-
    trate appoints a guardian ad litem under this subdivision, the judge’s or
    magistrate’s order shall [i] limit the appointment in scope and duration, and
    [ii] direct the guardian ad litem to take only the specific action required or
    to answer specific questions posed by the judge or magistrate . . . .’’). Thus,
    the guardian ad litem’s role may be limited, particularly when the issue to
    be decided is one in which the ‘‘best interests’’ standard no longer applies.
