    NASH STREET, LLC v. MAIN STREET AMERICA
    ASSURANCE COMPANY ET AL.
    (SC 20389)
    Robinson, C. J., and Palmer, McDonald, D’Auria,
    Mullins, Kahn and Ecker, Js.*
    Syllabus
    The plaintiff sought to recover proceeds allegedly due under a commercial
    general liability insurance policy issued by the defendant insurer to its
    insured, B Co. The plaintiff contracted with B Co. to renovate the plain-
    tiff’s damaged house, including site grading and foundation work, which
    involved, inter alia, the lifting of the house off of the foundation. The
    house collapsed after it was lifted by B Co.’s subcontractor. At the time
    of the collapse, the only work being performed on the house was related
    to the lifting. The plaintiff brought a separate action against B Co. for
    property damage arising from the collapse. B Co. tendered defense of
    the case to the defendant pursuant to the insurance policy, and the
    defendant declined to defend. The plaintiff subsequently brought the
    present action against the defendant, seeking recovery under a default
    judgment that the plaintiff had secured against B Co. in the separate
    action. The trial court granted the defendant’s motion for summary
    judgment and rendered judgment thereon, concluding that the defendant
    had no duty to defend or to indemnify B Co. based on the applicability
    of two provisions in the insurance policy excluding coverage for property
    damage to ‘‘that particular part of real property’’ on which the insured
    or anyone working on the insured’s behalf is ‘‘performing operations if
    the property damage arises out of those operations’’ and for property
    damage to ‘‘that particular part of any property that must be restored,
    repaired or replaced because’’ the insured’s work ‘‘was incorrectly per-
    formed on it.’’ The plaintiff thereafter appealed, claiming that the trial
    court improperly granted the defendant’s motion for summary judgment
    because, at the time B Co. tendered defense of the case to the defendant,
    there existed at least a possibility that the complaint alleged a liability
    covered under B Co.’s insurance policy that would have triggered the
    defendant’s duty to defend. More specifically, the plaintiff claimed that
    the defendant had a duty to defend B Co. because the complaint alleged
    damage only to the house and interior renovation work, whereas the
    two relevant policy exclusions precluded coverage only for the defective
    work to the foundation itself and not for damage to the rest of the
    house. Held that the trial court improperly granted the defendant’s
    motion for summary judgment, that court having incorrectly determined
    that the two exclusions relieved the defendant of its duty to defend B
    Co. in the plaintiff’s action against B Co., as there was a possibility that
    the damages the plaintiff alleged in that action were not excluded under
    the policy; numerous courts, including this court, have recognized that
    legal uncertainty can give rise to an insurer’s duty to defend, there was
    legal uncertainty in the present case as to the meaning and applicability
    of the two exclusions, Connecticut law favors a narrow construction
    of exclusions and requires that ambiguous provisions be construed in
    favor of the insured, many other courts have interpreted exclusions
    with the ‘‘that particular part’’ language in a manner favoring coverage,
    and neither this court nor the Appellate Court has previously interpreted
    exclusions identical to those at issue in the present case.

    Procedural History
    Action to recover proceeds allegedly due under a
    commercial general liability insurance policy issued by
    the named defendant, and for other relief, brought to
    the Superior Court in the judicial district of Ansonia-
    Milford, where the court, Tyma, J., denied the plaintiff’s
    motion for summary judgment and granted the named
    defendant’s motion for summary judgment and ren-
    dered judgment thereon, from which the plaintiff
    appealed. Reversed; further proceedings.

    for the appellee (named defendant).
    Opinion
    McDONALD, J. The dispositive issue before us is
    whether the defendant insurer had a duty to defend an
    action brought against its insured in an underlying
    action alleging property damage resulting from a house
    that collapsed while being lifted off its foundation. The
    insurance policy under review contained clauses
    excluding coverage for damage that occurs to ‘‘that
    particular part’’ of real property on which the insured
    was working. In this case, brought under the direct
    action statute; see General Statutes § 38a-321; the plain-
    tiff, Nash Street, LLC, appeals from the judgment of
    the trial court, which granted the motion for summary
    judgment filed by the named defendant, Main Street
    America Assurance Company.1 The plaintiff claims that
    the trial court improperly granted the defendant’s
    motion for summary judgment because, at the time the
    insured, New Beginnings Residential Renovations, LLC,
    tendered defense of the underlying action to the defen-
    dant, there existed at least a possibility that the com-
    plaint alleged a liability that was covered under New
    Beginnings’ insurance policy and, thus, triggered the
    defendant’s duty to defend. We agree with the plaintiff
    and reverse the judgment of the trial court.
    The parties stipulated to the following facts in the
    direct action. The plaintiff’s property in Milford needed
    repairs after being damaged by Hurricanes Sandy and
    Irene. The plaintiff contracted with New Beginnings to
    renovate the house, including site grading and founda-
    tion work for which the house would be lifted and
    temporarily placed onto cribbing. A subcontractor was
    retained to lift the house and to do concrete work on
    the foundation.
    While the subcontractor was lifting the house in prep-
    aration for the foundation work, the house ‘‘shifted off
    the supporting cribbing and collapsed.’’ At the time of
    the collapse, the only work being performed on the
    house was related to the lifting. New Beginnings and/
    or its subcontractor caused the collapse by failing to
    ensure that the cribbing was secure. As a result, the
    house sustained ‘‘extensive physical damage . . . .’’
    The plaintiff brought an action against, inter alios,
    New Beginnings for property damage arising out of the
    collapse. The complaint alleged, in pertinent part, that
    ‘‘New Beginnings was negligent in the performance of
    its work in the following respects . . . New Beginnings
    and/or its subcontractors negligently constructed or
    assembled the cribbing [that] caused the collapse; and
    . . . New Beginnings and/or its subcontractors failed
    to ensure that the cribbing properly supported the
    house. . . . As a result of New Beginnings’ negligence,
    the cribbing failed, causing damage to the house and
    the renovation work therein.’’ New Beginnings tendered
    defense of the case to the defendant pursuant to a
    commercial general liability insurance policy, and the
    defendant declined to defend. The plaintiff was
    awarded a default judgment against New Beginnings
    for its failure to plead in the amount of $558,007.16. No
    part of the judgment has been paid.
    The record reveals the following additional facts. The
    plaintiff brought the present action against the defen-
    dant under the direct action statute, seeking recovery
    for the judgment against New Beginnings. In response,
    the defendant filed an answer and five special defenses,
    each claiming that the alleged damages were not cov-
    ered by the insurance policy.2 Both parties moved for
    summary judgment. The plaintiff argued that there was
    no genuine issue of material fact that there is coverage
    under the policy and that the exclusions are inapplica-
    ble. The defendant argued that there is no genuine issue
    of material fact that two of the policy’s ‘‘business risk’’
    exclusions—k (5) and (6)—preclude coverage.
    Under exclusion k (5), the policy excludes coverage
    for property damage to ‘‘[t]hat particular part of real
    property on which you or any contractor or subcontrac-
    tor working directly or indirectly on your behalf is per-
    forming operations, if the ‘property damage’ arises out
    of those operations . . . .’’ Under exclusion k (6), the
    policy excludes coverage for property damage to ‘‘[t]hat
    particular part of any property that must be restored,
    repaired or replaced because ‘your work’ was incor-
    rectly performed on it.’’
    The plaintiff argued that ‘‘that particular part’’ of the
    property on which New Beginnings and/or its subcon-
    tractor were working was ‘‘the site grading and founda-
    tion work underneath the house . . . [and that] New
    Beginnings [and/or its subcontractor were] not per-
    forming any renovation or other work on the house
    itself.’’ Thus, the plaintiff contended, it did not seek to
    recover for the damage to the work being done under-
    neath the house—that work would be excluded under
    k (5) and (6). Rather, the plaintiff sought to recover for
    the damage to the house, including renovation work
    that had allegedly been completed a year before the
    collapse.
    The defendant argued that ‘‘that particular part’’ of
    the property on which the subcontractor was per-
    forming operations was the whole house because the
    whole house was being lifted. It further argued that the
    possibility that the house might collapse while being
    raised was a foreseeable risk in undertaking those oper-
    ations. The defendant reasoned that all damage that
    occurs to a house under these circumstances is a ‘‘busi-
    ness risk’’ that falls squarely within exclusions k (5)
    and (6).
    In due course, the trial court issued a memorandum
    of decision, denying the plaintiff’s motion for summary
    judgment and granting the defendant’s motion for sum-
    mary judgment. The court stated that the parties agreed
    that the only issue was whether exclusions k (5) or (6)
    ‘‘preclude[d] coverage for the property damage to the
    entire house that occurred as a result of the [house’s]
    shifting [off of] the cribbing and collapsing at the time
    that grading and foundation work was being per-
    formed.’’ The court concluded that exclusions k (5) and
    (6) were clear and unambiguous, and ‘‘ ‘that particular
    part of real property’ ’’ on which New Beginnings or
    the subcontractor was performing operations was the
    entire house. As such, the court concluded that these
    exclusions precluded coverage, and, thus, the defen-
    dant had no duty to defend or to indemnify New Begin-
    nings.
    The plaintiff appealed to the Appellate Court from
    the trial court’s judgment in favor of the defendant, and
    the appeal was transferred to this court.
    On appeal, the plaintiff contends that the trial court
    improperly granted the defendant’s motion for sum-
    mary judgment because the court conflated the duty to
    defend, which arises when there is a possibility of
    coverage, with the duty to indemnify, which arises when
    there actually is coverage. The plaintiff argues that
    the defendant had a duty to defend New Beginnings
    because the plaintiff’s complaint alleged damage to the
    house and interior renovation work, which, under a
    correct interpretation of exclusions k (5) and (6), was
    separate from the foundation work. Specifically, the
    plaintiff argues that, under Connecticut law, either the
    exclusions must be read narrowly, so as not to preclude
    coverage, or, alternatively, the exclusions are ambigu-
    ous and must be construed in favor of coverage. Under
    either interpretation, the plaintiff contends, there was a
    possibility of coverage because the exclusions preclude
    coverage only for the defective work to the foundation
    itself and not for the damage to the rest of the house.
    For its part, the defendant contends that the trial court’s
    granting of summary judgment in its favor was proper
    because exclusions k (5) and (6) unambiguously pre-
    clude coverage. We conclude that summary judgment
    was improper because exclusions k (5) and (6) did
    not relieve the defendant of its duty to defend New
    Beginnings in the underlying action.3
    Whether the trial court properly rendered summary
    judgment in favor of the defendant is a question of law
    subject to our plenary review. See Tannone v. Amica
    Mutual Ins. Co., 
    329 Conn. 665
    , 671, 
    189 A.3d 99
     (2018).
    ‘‘Practice Book § 17-49 provides that summary judg-
    ment shall be rendered forthwith if the pleadings, affida-
    vits 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. . . . On appeal, we must determine whether
    the legal conclusions reached by the trial court are
    legally and logically correct and whether they find sup-
    port in the facts set out in the memorandum of decision
    of the trial court.’’ (Internal quotation marks omitted.)

    284 Conn. 193
    ,
    198–99, 
    931 A.2d 916
     (2007).
    We begin that review by noting that the plaintiff
    brought this action under our direct action statute,
    § 38a-321, which places the plaintiff in the shoes of the
    insured, subject to all the same rights and protections
    as the insured. See Samelko v. Kingstone Ins. Co., 
    329 Conn. 249
    , 262, 
    184 A.3d 741
     (2018); Black v. Goodwin,
    Loomis & Britton, Inc., 
    239 Conn. 144
    , 149 n.7, 
    681 A.2d 293
     (1996). The plaintiff’s claim, then, turns only
    on whether there was a possibility of coverage that
    triggered the insurer’s duty to defend. See R.T. Vander-
    bilt Co. v. Continental Casualty Co., 
    273 Conn. 448
    ,
    470–71, 
    870 A.2d 1048
     (2005) (‘‘[A]n insurer’s duty to
    defend its insured is triggered without regard to the
    merits of its duty to indemnify. . . . [So, when] an
    insurer is guilty of a breach of its contract to defend,
    it is liable to pay to the insured not only his reasonable
    expenses in conducting his own defense but, in the
    absence of fraud or collusion, the amount of a judgment
    [or settlement] obtained against the insured up to the
    limit of liability fixed by its policy.’’ (Citation omitted;
    internal quotation marks omitted.)); Wentland v. Amer-
    ican Equity Ins. Co., 
    267 Conn. 592
    , 600, 
    840 A.2d 1158
    (2004) (in action brought by plaintiff against insurer
    after settling with insured, plaintiff need not establish
    insured’s liability or resolve coverage dispute if there
    was possibility of coverage); Black v. Goodwin,
    Loomis & Britton, Inc., supra, 156, 160 (explaining, in
    action for breach of duty to defend brought under § 38a-
    321, that, ‘‘to recover the amount of the settlement from
    the insurer, the insured need not establish actual liabil-
    ity to the party with whom it has settled so long as . . .
    a potential liability on the facts known to the [insured
    is] shown to exist’’ and that ‘‘insurer may not hide
    behind the language of the policy after the insurer aban-
    dons its insured’’ (internal quotation marks omitted)).
    This is because ‘‘the duty to defend is broader than
    the duty to indemnify. . . . An insurer’s duty to defend
    is triggered if at least one allegation of the complaint
    falls even possibly within the coverage.’’ (Internal quo-
    tation marks omitted.) Travelers Casualty & Surety
    Co. of America v. Netherlands Ins. Co., 
    312 Conn. 714
    ,
    739, 
    95 A.3d 1031
     (2014). ‘‘The obligation of the insurer
    to defend does not depend on whether the injured party
    will successfully maintain a cause of action against the
    insured but on whether he has, in his complaint, stated
    facts [that] bring the injury within the coverage. . . .
    If an allegation of the complaint falls even possibly
    within the coverage, then the [insurer] must defend the
    insured.’’ (Citation omitted; internal quotation marks
    omitted.) Wentland v. American Equity Ins. Co., 
    supra,
    267 Conn. 600
    . ‘‘In contrast to the duty to defend, the
    duty to indemnify is narrower: while the duty to defend
    depends only on the allegations made against the
    insured, the duty to indemnify depends [on] the facts
    established at trial and the theory under which judg-
    ment is actually [rendered] in the case. . . . Thus, the
    duty to defend is triggered whenever a complaint alleges
    facts that potentially could fall within the scope of cov-
    erage . . . .’’ (Internal quotation marks omitted.) Trav-
    elers Casualty & Surety Co. of America v. Netherlands
    Ins. Co., 
    supra, 739
    .
    Because all that is necessary to trigger an insurer’s
    duty to defend is a possibility of coverage, any uncer-
    tainty as to whether an alleged injury is covered works
    in favor of providing a defense to an insured, and uncer-
    tainty may be either factual or legal. See, e.g., Hugo
    Boss Fashions, Inc. v. Federal Ins. Co., 
    252 F.3d 608
    ,
    620 (2d Cir. 2001); see also, e.g., Wentland v. American
    Equity Ins. Co., supra, 
    267 Conn. 601
    . Factual uncer-
    tainty arises when it is unclear from the face of the
    complaint whether an alleged injury occurred in a man-
    ner that is covered by the policy. See Hugo Boss Fash-
    ions, Inc. v. Federal Ins. Co., supra, 620–22. For exam-
    ple, if a policy was active only for the 2019 calendar
    year and a complaint did not specify when the alleged
    injury took place, there would be factual uncertainty
    as to whether the injury was covered because it is
    impossible to know from the face of the complaint
    whether the alleged injury took place during the cover-
    age period. This factual uncertainty would give rise to
    a duty to defend, lasting at least until a court determined
    when the injury occurred. See, e.g., id., 621–22.
    Legal uncertainty arises when it is unclear how a
    court might interpret the policy language at issue, and,
    as a result, it is unclear whether the alleged injury falls
    within coverage. See id. Legal uncertainty can arise in
    at least two ways. First, as this court has recognized,
    ambiguous policy language can give rise to the duty to
    defend. See, e.g., Wentland v. American Equity Ins.
    Co., supra, 
    267 Conn. 601
    . Second, a duty to defend
    may arise if there is a question as to whether ‘‘the cases
    governing the insurance policy [will] be read to impose
    coverage in a given situation . . . .’’ Hugo Boss Fash-
    ions, Inc. v. Federal Ins. Co., supra, 
    252 F.3d 620
    . That
    is, when there is a split of authority in other jurisdictions
    as to the meaning of a particular policy provision, and
    no appellate authority in the relevant jurisdiction has
    opined on the matter, the uncertainty as to how a court
    might interpret the policy gives rise to the duty to
    defend. See American Best Food, Inc. v. Alea London,
    Ltd., 
    168 Wn. 2d 398
    , 410, 
    229 P.3d 693
     (2010).
    Numerous courts, including this one, have recognized
    that legal uncertainty can give rise to an insurer’s duty
    to defend. See, e.g., Hugo Boss Fashions, Inc. v. Federal
    Ins. Co., supra, 
    252 F.3d 620
     (under New York law, duty
    to defend is triggered by uncertainty as to whether

    This court has recognized the first type of legal uncer-
    tainty, caused by ambiguous policy language. See Went-
    land v. American Equity Ins. Co., supra, 
    267 Conn. 601
    . We have not had occasion, however, to consider
    the second. We find instructive the following cases from
    the United States Court of Appeals for the Second Cir-
    cuit and the Washington Supreme Court, in which the
    courts concluded that, when no appellate authority of
    a jurisdiction has interpreted particular policy language,
    but courts in other jurisdictions have interpreted the
    same language in a manner that could result in cover-
    age, the legal uncertainty as to how a court might inter-
    pret the language may give rise to a duty to defend.4
    In Hugo Boss Fashions, Inc. v. Federal Ins. Co.,
    supra, 
    252 F.3d 608
    , the plaintiff clothing companies
    and their parent company, which were referred to col-
    lectively as Hugo Boss in the Second Circuit’s decision,
    were sued for, inter alia, trademark infringement for
    using the word ‘‘BOSS’’ on certain products, allegedly
    violating a concurrent use agreement they had with a
    competitor, and the plaintiffs tendered defense of the
    case to their insurer, the defendant. See 
    id.,
     610–12.
    The insurer declined to defend on the ground that an
    exclusion precluded coverage because ‘‘BOSS’’ did not
    fall under the term ‘‘trademarked slogans,’’ within the
    meaning of the policy. (Internal quotation marks omit-
    ted.) 
    Id.,
     612–13. Whether there was coverage, there-
    fore, depended on the meaning of the words ‘‘trade-
    marked slogan.’’ Looking to federal case law, the
    Second Circuit determined that the overwhelming
    majority of courts had concluded that ‘‘trademarked
    slogan’’ was unambiguous, which would preclude cov-
    erage under the facts of the case. 
    Id.,
     618–20. The court
    noted, however, that one United States District Court
    decision from the Southern District of New York had
    concluded that ‘‘trademarked slogan’’ was ambiguous.
    
    Id.,
     620–21 and n.11. The Second Circuit concluded that
    this contrary decision ‘‘rendered uncertain the question
    of whether the courts would deem the term ‘trade-
    marked slogan’ to be unambiguous.’’5 (Emphasis omit-
    ted.) 
    Id.,
     621 n.11.
    The court explained that the question of whether ‘‘the
    cases governing the insurance policy [would] be read
    to impose coverage . . . [would] ultimately be
    resolved by [the] courts . . . [perhaps] in favor of the
    insurer, thereby precluding coverage and the duty to
    indemnify. But until they are, the insurer cannot avoid
    its duty to defend.’’ 
    Id., 620
    . The court continued: ‘‘It
    was, therefore, incumbent upon [the insurer] to under-
    take a defense of Hugo Boss until the uncertainty sur-
    rounding the term [trademarked slogan] was resolved.
    Had [the insurer] sought a declaratory judgment imme-
    diately upon Hugo [Boss’] filing of its insurance claim,
    a court might have eliminated this uncertainty by read-
    ing the term as [the insurer] has claimed it should be
    read . . . . Moreover, it might have done so before
    [the insurer] expended a great deal of money putting
    up a defense for Hugo Boss. But until such a ruling
    issued, the question of whether [the insurer] might be
    held liable to indemnify Hugo Boss was in doubt. And,
    given this doubt, [the insurer’s] failure to provide a
    defense . . . was a violation of its contractual duties.’’
    
    Id.,
     622–23.
    Similarly, in American Best Food, Inc. v. Alea Lon-
    don, Ltd., 
    supra,
     
    168 Wn. 2d 398
    , the Washington
    Supreme Court considered ‘‘whether an insurer
    breached its duty to defend as a matter of law when,
    relying [on] an equivocal interpretation of case law, it
    gave itself the benefit of the doubt rather than give that
    benefit to its insured.’’ 
    Id., 402
    . After a man was shot
    nine times by another patron at the plaintiff’s nightclub,
    club security guards ‘‘dumped him on the sidewalk.’’
    (Internal quotation marks omitted.) 
    Id.,
     402–403. The
    defendant, the club’s insurer, declined to defend the
    injured man’s action against the club on the ground
    that an ‘‘assault and battery’’ exclusion in the policy
    precluded coverage for the incident. 
    Id., 403
    . Washing-
    ton courts had never before interpreted the exclusion,
    but many other courts had, finding a distinction
    between preassault and postassault negligence. See 
    id.,
    407–408. Because the complaint in the injured man’s
    underlying action against the club alleged both preas-
    sault and postassault negligence, if Washington were
    to adopt the same distinction, the exclusion would not
    apply to all of the alleged injuries. The Washington
    Supreme Court concluded that ‘‘[t]he lack of any Wash-
    ington case directly on point and a recognized distinc-
    tion between preassault and postassault negligence in
    other states presented a legal uncertainty with regard
    to [the insurer’s] duty. Because any uncertainty works
    in favor of providing a defense to an insured, [the insur-
    er’s] duty to defend arose when [the injured man]
    brought [the action] against [the nightclub].’’ 
    Id., 408
    .
    Applying these principles to the present case, we are
    mindful that our inquiry is not whether exclusions k
    (5) and (6) actually preclude coverage; nor does this
    case require us to determine conclusively what those
    exclusions mean. The only question we must answer
    is whether there was any possibility of coverage at the
    time New Beginnings tendered defense to the defen-
    dant.6 See, e.g., Travelers Casualty & Surety Co. of
    America v. Netherlands Ins. Co., supra, 
    312 Conn. 739
    (‘‘[a]n insurer’s duty to defend is triggered if at least one
    allegation of the complaint falls even possibly within the
    coverage’’ (emphasis added; internal quotation marks
    omitted)); Capstone Building Corp. v. American
    Motorists Ins. Co., 
    308 Conn. 760
    , 817, 
    67 A.3d 961
    (2013) (‘‘the insured is not required to prove actual
    liability, only potential liability on the facts known to
    the [insured]’’ (internal quotation marks omitted)); Soto

    155 Conn. 104
    , 113,
    
    230 A.2d 21
     (1967) (because court found insurer
    breached duty to defend, court found it ‘‘unnecessary
    to reach [the] issue’’ of whether insurer also had
    breached its duty to indemnify). More specifically,
    because the plaintiff alleged damage to ‘‘the house and
    the renovation work therein,’’ we must consider
    whether legal uncertainty existed regarding the cover-
    age issue in dispute. That is, was it possible, at the time
    New Beginnings tendered defense to the defendant, that
    this court, if presented with the issue, could construe
    ‘‘that particular part’’ in exclusions k (5) and (6) to
    mean that any portion of the alleged damage would fall
    outside the scope of the exclusions?
    The plaintiff contends that, under Connecticut law,
    either the exclusions must be construed narrowly, so
    as not to preclude coverage, or, alternatively, the exclu-
    sions are ambiguous and must be construed in favor
    of coverage. Under either construction, the plaintiff
    argues, there was a possibility of coverage because
    the exclusions cover only the defective work on the
    foundation and do not exclude coverage for the damage
    to the house or interior renovations caused by the defec-
    tive work done underneath the house. The defendant
    contends that, under the facts of this case—in which
    the insured was required to lift the entire house—exclu-
    sions k (5) and (6) unambiguously exclude coverage
    for all damage to the house caused by the collapse,
    which was a foreseeable business risk for a business
    that lifts houses.7
    Exclusions k (5) and (6) are not unique to the insur-
    ance policy in the present case; they are standard exclu-
    sions used in policies across the country, and there
    has been considerable litigation as to the exclusions’
    meaning and applicability. Courts have generally inter-
    preted the ‘‘that particular part’’ language in one of
    three ways, adopting either a broad or narrow construc-
    tion, or concluding that the language is ambiguous.
    Under the broad interpretation, ‘‘that particular part’’
    excludes all damage to the insured’s work product
    caused by the insured’s defective work, even if the
    scope of the damage far exceeds the portion of the
    property on which the defective work was actually per-
    formed. See, e.g., Jet Line Services, Inc. v. American
    Employers Ins. Co., 
    404 Mass. 706
    , 711, 
    537 N.E.2d 107
    (1989) (all damage to tank caused by explosion was
    excluded from coverage, even though contractor was
    cleaning only bottom of tank at time of explosion).
    Under the narrow interpretation, ‘‘that particular part’’
    applies only to the specific components on which the
    insured performed defective work and not to wider
    damage to the insured’s work product caused by the
    defective work. See, e.g., Mid-Continent Casualty Co.
    v. JHP Development, Inc., 
    557 F.3d 207
    , 215, 217 (5th
    Cir. 2009) (under Texas law, exclusion applied only to
    exterior portions of building that contractor did not
    properly water seal, not to interior portions that sus-
    tained water damage as result). Finally, courts that
    determine that both, or other, interpretations are rea-
    sonable conclude that the language is ambiguous and,
    as a result, construe the language in favor of the insured.
    See, e.g., Cogswell Farm Condominium Assn. v. Tower
    Group, Inc., 
    167 N.H. 245
    , 249, 252, 
    110 A.3d 822
     (2015).
    Consistent with our precedent favoring a narrow
    interpretation of insurance policy exclusions; see, e.g.,
    Nationwide Mutual Ins. Co. v. Pasiak, 
    327 Conn. 225
    ,
    239, 
    173 A.3d 888
     (2017) (‘‘[w]hen construing exclusion
    clauses, the language should be construed in favor of
    the insured unless [the court] has a high degree of
    certainty that the policy language clearly and unambigu-
    ously excludes the claim’’ (internal quotation marks
    omitted)); several courts, including the federal Courts
    of Appeals for the Fifth and Sixth Circuits, have adopted
    the narrow interpretation of ‘‘that particular part.’’ See,
    e.g., Fortney & Weygandt, Inc. v. American Manufac-
    turers Mutual Ins. Co., 
    595 F.3d 308
    , 311 (6th Cir. 2010)
    (adopting reasoning and conclusion of Fifth Circuit’s
    decision in Mid-Continent Casualty Co. v. JHP Devel-
    opment, Inc., supra, 
    557 F.3d 215
    , 217, with respect to
    k (6)8 and noting that words ‘‘ ‘[t]hat particular part’
    . . . are trebly restrictive, straining to the point of awk-
    wardness to make clear that the exclusion applies only
    to building parts on which defective work was per-
    formed, and not to the building generally’’); Mid-Conti-
    nent Casualty Co. v. JHP Development, Inc., supra, 218
    (under plain reading of policy, exclusions k (5) and (6)
    apply only to property damage to particular part of
    property that was subject of defective work). These
    decisions from federal courts of appeals, combined with
    Connecticut’s preference for interpreting exclusions
    narrowly and the lack of a Connecticut appellate author-
    ity on point, demonstrate that it was possible that this
    court could adopt a narrow interpretation of exclusions
    k (5) and (6). In doing so, we might have concluded
    that ‘‘that particular part’’ of the house on which the
    defective work was performed was only that portion
    underneath the house that was not properly supported,
    leading to the collapse of and damage to the entire
    house.
    Numerous other courts, including the Supreme
    Courts of New Hampshire and Missouri, have con-
    cluded that the exclusions are ambiguous and, there-
    fore, must be construed in favor of coverage. See
    Columbia Mutual Ins. Co. v. Schauf, 
    967 S.W.2d 74
    , 80
    (Mo. 1998) (‘‘applying the exclusion to real property
    . . . is far from easy . . . [because] [h]ouses and
    buildings can be divided into so many parts that
    attempting to determine which part or parts are the
    subject of the insured’s operations can produce several
    reasonable conclusions’’); Cogswell Farm Condomin-
    ium Assn. v. Tower Group, Inc., supra, 
    167 N.H. 251
    –52
    (exclusion k (6) was ambiguous because both broad and
    narrow interpretations were reasonable). Connecticut
    law also requires that ambiguous insurance policy pro-
    visions be construed in favor of coverage. See, e.g.,
    Nationwide Mutual Ins. Co. v. Pasiak, supra, 
    327 Conn. 238
    –39 (‘‘[W]hen the words of an insurance contract
    are, without violence, susceptible of two [equally
    responsible] interpretations, that which will sustain the
    claim and cover the loss must, in preference, be
    adopted. . . . [T]his rule of construction favorable to
    the insured extends to exclusion clauses.’’ (Internal
    quotation marks omitted.)); see also Travelers Casu-
    alty & Surety Co. of America v. Netherlands Ins. Co.,
    supra, 
    312 Conn. 740
     (‘‘if an ambiguity arises that cannot
    be resolved by examining the parties’ intentions . . .
    [c]ourts . . . often apply the contra proferentem rule
    and interpret a policy against the insurer’’ (internal quo-
    tation marks omitted)). These decisions from sister
    state supreme courts, combined with Connecticut’s rule
    regarding the interpretation of ambiguous policy provi-
    sions and the lack of a Connecticut appellate decision
    on point, suggest that it is also possible that this court
    might have concluded that exclusions k (5) and (6) are
    ambiguous and, thus, must be construed against the
    defendant. In doing so, we might have concluded that
    the exclusions do not cover the full extent of the dam-
    ages alleged in the complaint.
    Faced with a lack of any Connecticut appellate
    authority on point and with numerous state supreme
    and federal appellate court cases that have adopted
    interpretations of exclusions k (5) and (6) that are con-
    sistent with Connecticut law and would favor the plain-
    tiff, the defendant was presented with a legal uncer-
    tainty with regard to its duty to defend.9 Because such
    an uncertainty works in favor of providing a defense
    to an insured, exclusions k (5) and (6) did not relieve
    the defendant of its duty to defend New Beginnings.
    Although our case law does not require it, the pru-
    dent, if not ordinary, course would have been for the
    defendant to defend its insured under a reservation of
    rights and separately pursue a declaratory judgment
    action to resolve the legal uncertainty at issue. See,
    e.g., Travelers Casualty & Surety Co. of America v.
    Netherlands Ins. Co., supra, 
    312 Conn. 726
    –27 (‘‘The
    purpose of a declaratory judgment action . . . is to
    secure an adjudication of rights [when] there is a sub-
    stantial question in dispute or a substantial uncertainty
    of legal relations between the parties. . . . [O]ur
    declaratory judgment statute provides a valuable tool
    by which litigants may resolve uncertainty of legal obli-
    gations.’’ (Internal quotation marks omitted.)); see also
    General Statutes § 52-29; Practice Book § 17-55. When
    an insurer declines to defend, it must accept the risk
    that a court may conclude that, by doing so, the insurer
    breached its duty to defend. See Travelers Casualty &
    Surety Co. of America v. Netherlands Ins. Co., supra,
    739–40 n.25. As the Appellate Court of Illinois has
    explained: ‘‘[The] [d]efendant [insurer] . . . unilater-
    ally determined that there was no possibility of cover-
    age for the damages alleged by the [plaintiff’s action]
    . . . . [The] [d]efendant’s unilateral decision . . . was
    simply a calculated gamble; however, under these cir-
    cumstances, we conclude that, even if there existed
    an exclusion that [the] defendant determined barred
    coverage, it improvidently chose to sit back and do
    nothing. . . . [When] there [is] a serious dispute . . .
    regarding whether [a] claim might possibly fall within
    policy coverage and give rise to a duty to defend, the
    insurer . . . should . . . seek a declaratory judgment
    as to its rights and obligations before or pending trial
    or defend the insured under [a] reservation of rights
    . . . .’’ (Citation omitted; internal quotation marks
    omitted.) Soto v. Country Mutual Ins. Co., supra, 
    2015 WL 5307297
    , *10.
    The defendant relies on four cases—one from a state
    supreme court and three from trial courts—that, it
    claims, involve facts and exclusions identical to those
    in this case. In each case, the court determined that
    ‘‘that particular part’’ excluded coverage for damage to
    the entire house. See Lafayette Ins. Co. v. Peerboom,
    
    813 F. Supp. 2d 823
    , 834 (S.D. Miss. 2011) (‘‘[u]nlike the
    insureds in [other cases], [the insured] performed work,
    not on the foundation only, but on the entire house
    . . . and this fact distinguishes the present case from
    . . . cases [in which] a contractor undertakes to work
    on a discrete part of a structure and defects in his work
    cause damage to other property’’); Auto-Owners Ins.
    Co. v. Chorak & Sons, Inc., Docket No. 07 C 4454,
    
    2008 WL 3286986
    , *3 (N.D. Ill. August 8, 2008) (‘‘[T]he
    structure on which [the insured] was working was the
    entire house . . . that is, [the insured] had to raise the
    entire house in order to complete the assigned task.

    and that incorrect performance caused damage to the
    house. Thus, the damage to the house caused by the
    operations is excluded from coverage . . . .’’ (Cita-
    tions omitted.)); Grinnell Mutual Reinsurance Co. v.
    Lynne, 
    686 N.W.2d 118
    , 125–26 (N.D. 2004) (‘‘We con-
    strue ambiguous contract provisions narrowly; how-
    ever, this case fits within even a narrow interpretation
    of the business risk exclusion. . . . The particular part
    of real property on which [the insured] was working
    was the house. Thus, damage to the house resulting
    from [the insured’s] work will not be covered by the
    policy due to the exclusions included in the policy.’’
    (Citations omitted.)); see also Barber v. Berthiaume,
    Superior Court, judicial district of New Haven, Docket
    No. CV-XX-XXXXXXX-S (October 19, 2009) (
    48 Conn. L. Rptr. 662
    , 663) (following Grinnell Mutual Reinsurance
    Co. v. Lynne, supra, 126, because it involved ‘‘an identi-
    cal fact pattern and issue’’). The defendant argues that,
    consistent with these cases, exclusions k (5) and (6)
    clearly and unambiguously exclude coverage for all of
    the damages alleged in the plaintiff’s complaint against
    New Beginnings and, thus, relieve the defendant of its
    duty to defend. We are not persuaded.
    Although the cases the defendant cites involve similar
    facts and identical exclusions to those in the present
    case, the cases are procedurally distinguishable, and the
    distinction is crucial because the different procedural
    postures require fundamentally different inquiries with
    respect to the duty to defend. In this case, the defendant
    declined to defend the underlying case, and the plaintiff
    thereafter won a judgment, which it seeks to collect
    from the defendant. On appeal, our inquiry into whether
    there was a duty to defend involves a retrospective
    examination of whether there was any possibility of
    coverage when New Beginnings tendered defense to
    the defendant. In contrast, in three of the four cases
    that the defendant cites, the insurers did not decline
    to defend their insureds; they agreed to defend under
    a reservation of rights and then brought declaratory
    judgment actions to determine whether they were
    required to defend cases that were then pending. See
    Lafayette Ins. Co. v. Peerboom, 
    supra,
     
    813 F. Supp. 2d 824
    ; Auto-Owners Ins. Co. v. Chorak & Sons, Inc.,
    supra, 
    2008 WL 3286986
    , *1; Grinnell Mutual Reinsur-
    ance Co. v. Lynne, supra, 
    686 N.W.2d 120
    –21. In those
    cases, the courts did not consider whether there was a
    possibility of coverage; they considered whether there
    actually was coverage.10 To determine if there is a duty
    to defend, a court considers whether there was uncer-
    tainty as to coverage at the relevant time. To determine
    if there is a duty to indemnify, as in the cases cited by
    the defendant, a court resolves any uncertainty as to
    coverage. See, e.g., DaCruz v. State Farm Fire & Casu-
    alty Co., 
    268 Conn. 675
    , 688, 
    846 A.2d 849
     (2004) (‘‘the
    duty to defend is triggered whenever a complaint alleges
    facts that potentially could fall within the scope of
    coverage, whereas the duty to indemnify arises only if
    the evidence adduced at trial establishes that the con-
    duct actually was covered by the policy’’ (emphasis in
    original)). The insurer’s use of the declaratory judgment
    action allows the court directly to address the duty to
    indemnify rather than only the duty to defend. But, as
    we have explained, the duty to defend is broader than
    the duty to indemnify, such that it is possible that, in
    a given case, if the duty to indemnify has not been
    resolved, an insurer will have a duty to defend, even if
    it ultimately has no duty to indemnify. See 
    id.
     The cases
    the defendant cites are unpersuasive because they pro-
    vide an analysis—whether there was actually cover-
    age—distinct from that which we undertake in this case,
    namely, whether there was any possibility of coverage.11
    Cf. American Best Food, Inc. v. Alea London, Ltd.,
    
    supra,
     
    168 Wn. 2d 411
     (‘‘[The insurer] relies [on] Lein-
    gang v. Pierce County Medical Bureau, Inc., 
    131 Wn. 2d 133
    , 
    930 P.2d 288
     (1997), which involved . . . the
    duty to indemnify, not the duty to defend. We do not
    find Leingang helpful because the duties to defend and
    indemnify are quite different.’’).
    In sum, we conclude that the trial court incorrectly
    determined that exclusions k (5) and (6) relieved the
    defendant of its duty to defend New Beginnings in the
    underlying action that the plaintiff brought against New
    Beginnings. At the time New Beginnings tendered
    defense of the underlying action to the defendant, there
    was a possibility that the damages the plaintiff alleged
    were covered by the policy. This possibility existed
    because of legal uncertainty as to the meaning and
    applicability of exclusions k (5) and (6), which arose
    from a combination of the following factors: Connecti-
    cut law favors a narrow construction of exclusions and
    requires that ambiguous provisions be construed in
    favor of the insured, multiple state supreme court and
    federal court of appeals decisions have interpreted
    exclusions identical to those in the present case in a
    manner favorable to the insured, and no Connecticut
    appellate authority has interpreted exclusions k (5) and
    (6). The defendant was not entitled to summary judg-
    ment because exclusions k (5) and (6) do not relieve the
    defendant of its duty to defend. Because the defendant’s
    summary judgment motion concerned only two of its
    special defenses; see footnote 2 of this opinion; we
    do not have occasion to consider the merits of the
    defendant’s three remaining special defenses. We leave
    it to the trial court to evaluate the remaining special
    defenses, should the defendant pursue them on remand.
    Cf. W. Horton & K. Bartschi, Connecticut Practice
    Series: Connecticut Rules of Appellate Procedure
    (2019–2020 Ed.) § 61-1, p. 67, authors’ comments (‘‘a
    decision by the Appellate Court reversing summary
    judgment . . . returns the case to the procedural pos-
    ture it would have been in if the trial court denied [the
    motion for] summary judgment’’).
    The judgment is reversed and the case is remanded

    Although the plaintiff’s complaint originally named Main Street America
    Assurance Company and Atlantic Casualty Insurance Company as defen-
    dants, the plaintiff subsequently withdrew its claim against Atlantic Casualty
    Insurance Company, and that entity is not a party to this appeal. We refer
    to Main Street America Assurance Company as the defendant.
    2
    In its special defenses, the defendant alleged that (1) the damages claimed
    by the plaintiff were not caused by an ‘‘occurrence,’’ as defined by the policy,
    (2) coverage is precluded by the exclusion in § II B 1 k (5) of the policy,
    (3) coverage is precluded by the exclusion in § II B 1 k (6) of the policy,
    (4) coverage is precluded by the exclusion in § II B 1 l of the policy, and
    (5) coverage is precluded by the exclusion in § II B 1 m of the policy. For
    convenience, we hereinafter refer to § II B 1 k (5) and (6) of the policy as
    k (5) and (6).
    3
    In granting the defendant’s motion for summary judgment, the trial court
    ruled that the defendant had neither a duty to defend nor a duty to indemnify
    New Beginnings in the underlying action. Because we conclude that, with
    respect to exclusions k (5) and (6), the defendant breached its duty to
    defend, we need not consider whether it has a duty to indemnify in order
    to reverse the trial court’s judgment as to both duties. Under this court’s
    precedent, an insurer that breaches its duty to defend has breached its
    contract with the insured, and it may not subsequently argue that the contract
    absolves it of its duty to indemnify. See, e.g., Capstone Building Corp.
    v. American Motorists Ins. Co., 
    308 Conn. 760
    , 817, 
    67 A.3d 961
     (2013)
    (recognizing as ‘‘central holding of our cases’’ principle that insurer that
    breaches duty to defend is ‘‘estop[ped] . . . from seek[ing] the protection
    of [the] contract in avoidance of its indemnity provisions’’ (internal quotation
    marks omitted)); see also Black v. Goodwin, Loomis & Britton, Inc., 
    239 Conn. 144
    , 149, 156, 
    681 A.2d 293
     (1996) (in action for breach of duty to
    defend brought under § 38a-321 by plaintiff against insurer, ‘‘insurer may
    not hide behind the language of the policy after the insurer abandons its
    insured’’ (internal quotation marks omitted)); Missionaries of the Co. of
    Mary, Inc. v. Aetna Casualty & Surety Co., 
    155 Conn. 104
    , 113–14, 
    230 A.2d 21
     (1967) (‘‘[t]he [insurer] having, in effect, waived the opportunity which
    was open to it to perform its contractual duty to defend under a reservation
    of its right to contest the obligation to indemnify the plaintiff, reason dictates
    that the [insurer] should reimburse the [insured] for the full amount of the
    obligation reasonably incurred by it’’). This is true regardless of whether
    the insured brings an action for recovery against the insurer or whether the
    judgment creditor brings an action against the insurer under § 38a-321. See
    Samelko v. Kingstone Ins. Co., 
    329 Conn. 249
    , 262, 
    184 A.3d 741
     (2018)
    (pursuant to § 38a-321, ‘‘the plaintiffs ultimately suffered the actual harm
    and are thus subrogated to all the rights of the insured’’). For the same
    reason, we do not reach the two other issues presented on appeal, namely,
    whether the trial court correctly concluded that (1) the phrase ‘‘that particu-
    lar part’’ in the policy exclusions is unambiguous, and (2) the plaintiff’s
    property damage is excluded from coverage under exclusions k (5) and (6).
    4
    We do not suggest that the absence of a controlling decision is, in and
    of itself, sufficient to give rise to the duty to defend. There must also be
    sufficient reason to conclude that the court could construe the policy lan-
    guage in favor of coverage. As the Second Circuit explained, ‘‘[t]here are,
    of course, cases in which the policy is so clear that there is no uncertainty
    in fact or law, and hence no duty to defend. . . . Under some circumstances,
    the allegations contained in the complaint against the insured will by them-
    selves eliminate all potential doubt and relieve the insurer of any duty to
    defend. [When], for example, a complaint alleges an intentional tort, and
    the insurance contract provides coverage only for harms caused by negli-
    gence, there would be no uncertainty as to the applicability of the policy
    exclusion, and hence, no duty to defend the particular [action] brought.’’
    (Footnote omitted.) Hugo Boss Fashions, Inc. v. Federal Ins. Co., supra,
    
    252 F.3d 620
    –21; see also Makarka v. Great American Ins. Co., supra, 
    14 P.3d 969
    –70 (‘‘A duty to defend may . . . exist [when] the resolution of a
    contested legal question may lead to covered liability against the insured.
    . . . [Nevertheless, when] coverage turns solely on the interpretation of
    policy language that has never been reviewed by [the Supreme Court of
    Alaska], that fact alone is not enough to create a possibility of coverage
    that require[s] a defense.’’ (Footnotes omitted.)).
    5
    We express no opinion as to whether we agree with the Second Circuit
    that, when a ‘‘vast majority’’ of courts agree as to the meaning of a policy
    provision, one contrary decision creates uncertainty sufficient to trigger an
    insurer’s duty to defend. Hugo Boss Fashions, Inc. v. Federal Ins. Co.,
    supra, 
    252 F.3d 618
    –20, 620–21 n.11. As we explain subsequently in this
    opinion, exclusions k (5) and (6) are standard provisions that are common
    in insurance policies across the country, and there is a significant split of
    authority as to the meaning of the exclusions, which creates a greater
    degree of uncertainty here than was present in Hugo Boss Fashions, Inc.
    Accordingly, we need not decide whether one contrary case gives rise to
    the duty to defend.
    6
    This approach incentivizes insurers to honor the contractual duty to
    defend insureds in cases in which there is a genuine dispute as to coverage
    arising from legal uncertainty. If the inquiry in this procedural posture were
    whether there was actually coverage, insurers could decline to defend, wait
    for judgment or settlement in the underlying action between the plaintiff and
    the insured, and then litigate the question of indemnity, thereby effectively
    avoiding the duty to defend. This would deprive insureds of a bargained
    for contractual right for which insureds pay a premium. It would also be
    inconsistent with our well established rule that an insurer that breaches its
    duty to defend cannot then use the contract to escape its indemnity obliga-
    tions. See Capstone Building Corp. v. American Motorists Ins. Co., 
    308 Conn. 760
    , 813 n.58, 
    67 A.3d 961
     (2013).
    Nevertheless, we note that, although an insurer who breaches its duty to
    defend may not litigate indemnity, the insurer may defend against a claim
    of breach of the duty to defend, in an action brought by either the insured
    or the injured party under the direct action statute, by establishing that there
    is no possibility that coverage existed and no legal uncertainty regarding
    the existence of such coverage. See, e.g., Tiedemann v. Nationwide Mutual
    Fire Ins. Co., 
    164 Conn. 439
    , 444, 
    324 A.2d 263
     (1973) (under predecessor
    to § 38a-321, insurer was able to argue that there was no possibility of
    coverage as defense to breach of duty to defend).
    7
    The defendant also argues that the purpose of a commercial general
    liability policy is to provide coverage for unforeseeable business risks, not
    to protect against foreseeable risks. Because the possibility that the insured
    might drop a house while lifting it was a foreseeable risk, the defendant
    contends that it would be contrary to the purpose of a commercial general
    liability insurance policy to conclude that exclusions k (5) and (6) do not
    apply to all damage to the house. We are not persuaded. The general purpose
    of a commercial general liability policy does not render other interpretations
    of the policy unreasonable. See Cogswell Farm Condominium Assn. v.
    Tower Group, Inc., 
    167 N.H. 245
    , 251, 
    110 A.3d 822
     (2015); see also Mid-
    Continent Casualty Co. v. JHP Development, Inc., 
    557 F.3d 207
    , 217 n.3
    (5th Cir. 2009) (‘‘[i]f insurers believe that this interpretation expands cover-
    age beyond that which commercial general liability insurance policies are
    supposed to provide, the . . . exclusion can of course be rewritten to make
    clear that it excludes this sort of property damage from coverage’’).
    8
    In many insurance policies containing identical or very similar exclu-
    sions, the exclusions are not lettered and numbered the same as the policy
    in this case. To avoid confusion, in discussing other cases construing these
    exclusions, we refer to all of these identical or similar exclusions as k (5)
    or (6), even if they were not so identified in the cases we discuss.
    9
    We recognize that these cases do not involve identical factual situations
    to the present case. We nevertheless find them instructive because, as we
    explained, there need only have been a mere possibility of coverage for the
    plaintiff to prevail. Additionally, the insurer bears the burden of proving
    that an exclusion applies. E.g., Nationwide Mutual Ins. Co. v. Pasiak, supra,
    
    327 Conn. 239
    . Because the burden lies with the insurer, the plaintiff need
    only sufficiently rebut the defendant’s argument.
    10
    The fourth case the defendant cites did not involve a declaratory judg-
    ment action, but that case dealt with indemnity, not the duty to defend.
    Indeed, that case makes no reference to the duty to defend. See Barber v.
    Berthiaume, supra, 
    48 Conn. L. Rptr. 662
    –63.
    11
    We note that, in the present case, the trial court’s memorandum of
    decision suffers from this same deficiency. See Nash Street, LLC v. Main
    Street America Assurance Co., Superior Court, judicial district of Ansonia-
    Milford, Docket No. CV-XX-XXXXXXX-S (December 13, 2018) (‘‘the sole issue
    to be decided is whether one or both policy exclusions preclude coverage
    for the property damage to the entire house that occurred as a result of the
    house shifting [off its] cribbing and collapsing at the time that grading and
    foundation work was being performed’’).
