OPINION
JEFFREY V. BROWN, Justice.
Appellants Weingarten Realty Management Company and Scottsdale Insurance Company appeal the trial court’s order granting summary judgment in favor of appellee Liberty Mutual Fire Insurance Company and denying their motion for partial summary judgment, for a new trial, for rehearing, and for clarification. We affirm.
I
This case involves an insurance-coverage dispute arising from an underlying lawsuit, Johnson, et ux. v. Weingarten Realty Management Co., No. 2002-46187. In that case, Connie Johnson, a manager of a Fashion Cents retail store, was assaulted by an unknown man who entered the store after business hours. Johnson sued her employer, Norstan Apparel Shops, Inc., d/b/a Fashion Cents, and Weingarten Realty Management Company (“Weingarten Management”), the entity she alleged leased the retail space occupied by Fashion Cents. However, the actual lessor was Weingarten Realty Investors (‘Weingarten Investors”), an entity separate and distinct from Weingarten Management. As its name suggests, Weingarten Management only managed the property. Although Johnson amended her petition seven times, the error was never corrected and Wein-garten Management never challenged the assertion.
In accordance with the lease between Norstan and Weingarten Investors, Nor-stan secured a general commercial-liability insurance policy through Liberty Mutual Fire Insurance Company. The policy contained an endorsement naming “all lessors of the premises leased to [Norstan] as additional insureds under the policy.” Weingarten Investors therefore became an insured lessor under the Liberty Mutual policy. Weingarten Management, however, maintained its own general commercial-liability policy with Scottsdale Insurance Company. When Johnson named Weingarten Management in her suit, [861]*861Weingarten Management initially defended pursuant to a self-insured retention, and Scottsdale later assumed the defense.
Shortly before trial, Weingarten Management made demand on Liberty Mutual for a defense as an additional insured under the Liberty Mutual policy between Norstan and Weingarten Investors. Liberty Mutual refused. The case was eventually tried and the jury found no liability on the part of Weingarten Management. Weingarten Management and Scottsdale then brought this suit against Liberty Mutual for $242,391.57 in incurred defense costs, arguing Liberty Mutual owed a duty to defend because Johnson named Wein-garten Management as a lessor in her underlying petition. Weingarten Management and Scottsdale concede Weingarten Management is not actually a lessor of the property. Nevertheless, the appellants argue that the mistaken allegation gave rise to a duty to defend because the “eight-corners rule” restricted the trial court from looking outside the pleadings and insurance policy to determine Weingarten Management was not the true lessor.
In considering the cross-motions for summary judgment, however, the trial court examined evidence extrinsic to Johnson’s petition in the underlying suit and the Liberty Mutual policy to determine Weingarten Management was not a lessor and therefore was not entitled to coverage under the Liberty Mutual policy’s “additional insured” endorsement. The trial court entered summary judgment in favor of Liberty Mutual and denied the appellants’ motions for partial summary judgment, for a new trial, for rehearing, and for clarification. This appeal followed.
II
In their first issue, the appellants argue the trial court was bound by the eight-corners rule and erred when it considered extrinsic evidence in granting Liberty Mutual’s motion for summary judgment. In their second issue, the appellants contend that in its examination of the extrinsic evidence, the trial court erred by finding as a matter of law that Weingarten Management was not a lessor because the terms of the lease require Norstan to name Weingarten Management as an additional insured. In their third issue, the appellants argue there was a fact issue as to whether Liberty Mutual was estopped from contesting that Weingarten Management was a lessor. In their fourth, fifth, and sixth issues, the appellants contend that the trial court erred to the extent its order can be read to deny the appellants’ subrogation rights, pre-tender defense costs, and attorneys’ fees. Because we find the trial court correctly entered summary judgment in favor of Liberty Mutual, and correctly denied the appellants’ motion for partial summary judgment, we overrule appellants’ issues one through three and consequently do not reach issues four through six.
A
We review the trial court’s grant of summary judgment de novo. Joe v. Two Thirty Nine Joint Venture, 145 S.W.3d 150, 156-57 (Tex.2004). A movant must establish its right to summary judgment by showing that no genuine issue of material fact exists and that it is entitled to judgment as a matter of law. Nixon v. Mr. Prop. Mgmt. Co., 690 S.W.2d 546, 548 (Tex.1985). We take as true all evidence favorable to the non-movant, and we indulge every reasonable inference and resolve any doubts in the non-movant’s favor. Joe, 145 S.W.3d at 157. We review a summary judgment for evidence that would enable reasonable and fair-minded jurors to differ in their conclusions. Wal-Mart Stores, Inc. v. Spates, 186 S.W.3d [862]*862566, 568 (Tex.2006) (per curiam). When we review cross-motions for summary judgment, we consider both motions and render the judgment that the trial court should have rendered. Coastal Liquids Transp., L.P. v. Harris Cnty. Appraisal Dist., 46 S.W.3d 880, 884 (Tex.2001).
The appellants first argue that the trial court erred in granting summary judgment in Liberty Mutual’s favor because it considered evidence in contravention of the eight-corners rule. The eight-corners rule provides that Texas courts may look only to the pleadings and the insurance policy to determine whether a duty to defend exists. Nat’l Union Fire Ins. Co. of Pittsburg, Pa. v. Merck. Fast Motor Lines, Inc., 939 S.W.2d 139, 141 (Tex.1997). The allegations in the pleadings are considered in light of the policy provisions without regard to them truth or falsity. Argonaut Sw. Ins. Co. v. Maupin, 500 S.W.2d 633, 635 (Tex.1973); Heyden Newport Chem. Corp. v. S. Gen. Ins. Co., 387 S.W.2d 22, 24 (Tex.1965). Even if the allegations are groundless, false, or fraudulent, the insurer is obligated to defend. Zurich Am. Ins. Co. v. Nokia, Inc., 268 S.W.3d 487, 491 (Tex.2008). Facts outside the pleadings, even those easily ascertained, are not ordinarily material to the determination of whether the duty to defend exists, and allegations against the insured are liberally construed in favor of coverage. See Nat’l Union, 939 S.W.2d at 141.
The Supreme Court of Texas has never expressly recognized an exception to the eight-corners rule. But it has acknowledged that other courts have drawn a “very narrow exception” allowing extrinsic evidence “only when relevant to an independent and discrete coverage issue, not touching on the merits of the underlying third-party claim.” GuideOne Elite Ins. Co. v. Fielder Road Baptist Church, 197 S.W.3d 305, 308 (Tex.2006); see also Pine Oak Builders, Inc. v. Great Am. Lloyds Ins. Co., 279 S.W.3d 650, 654 (Tex.2009). In GuideOne, the court noted the Fifth Circuit’s observation that if the Supreme Court of Texas were to recognize an exception to the eight-corners rule, it would likely do so only under circumstances where “it is initially impossible to discern whether coverage is potentially implicated and when the extrinsic evidence goes solely to a fundamental issue of coverage which does not overlap with the merits of or engage the truth or falsity of any facts alleged in the underlying case.” 197 S.W.3d at 308-09 (citing Northfield Ins. Co. v. Loving Home Care, Inc., 363 F.3d 523, 531 (5th Cir.2004)) (emphasis in original). The GuideOne court resolved the case before it without expressly approving of this exception because the extrinsic evidence in that case was relevant to both coverage and the merits, so the exception did not apply. Id. at 309.
The exception was first articulated in International Service Insurance Co. v. Boll, 392 S.W.2d 158 (Tex.Civ.App.-Houston 1965, writ ref'd n.r.e.). In Boll, the insured’s automobile-liability policy excluded coverage of “any claim arising from accidents which occur while any automobile is being operated by Roy Hamilton Boll.” Id. at 160. Roy was the insured’s only son. Id. The suit brought against the insured alleged that the insured’s son drove the automobile in question but did not name Roy expressly. Id. The parties later stipulated, however, that the son referred to in the petition was indeed Roy. Id. The court considered the stipulation and found the insurer owed no duty to defend, reasoning that an insurer “cannot be called on to defend a suit against the [insured] in which the petition upon its [863]*863face alleges a state of facts not covered by but excluded from the provisions of the policy.” Id. In the GuideOne decision, the supreme court observed that the extrinsic evidence in Boll “went strictly to the coverage issue” and “did not contradict any allegation in the third-party claimant’s pleadings material to the merits of that underlying claim.” GuideOne, 197 S.W.3d at 310. In other words, the insurer did not claim Roy Hamilton Boll was not liable for the accident. Rather, the insurer argued that even if he were, there were no potential underlying facts under which his liability could be covered by his father’s policy. See Boll, 392 S.W.2d at 161 (“Under the facts of this case the petitions filed against [Roy’s father] cannot be construed to allege a claim potentially within the coverage of the policy of insurance in question.”).
The Texarkana court of appeals followed Boll when it faced a similar scenario in Cook v. Ohio Casualty Insurance Co., 418 S.W.2d 712 (Tex.Civ.App.-Texarkana 1967, no writ). The policy in Cook excluded coverage where the insured was “driving an automobile owned by a relative who was a resident of the same household.” Id. at 714. The insured stipulated that she was living with her mother and was driving her mother’s 1953 Studebaker at the time of the accident. Id. The Cook court followed Boll and held that the trial court could consider extrinsic evidence. But the Cook court went further by attempting to square its decision with the supreme court’s directive to consider a complainant’s allegations “without reference to truth or falsity” and “without reference to what the parties know or believe the true facts to be.” See Heyden, 387 S.W.2d at 24. In doing so, the Cook court contrasted Boll, in which the insurer’s position was that the policy excluded coverage for liability incurred by the insured’s son for any claim, regardless of merit, with the supreme court’s holding in Heyden, in which the insurer’s ultimate position was that the underlying claim could easily be proved meritless. See Cook, 418 S.W.2d at 715. The court went on to surmise that the supreme court had implicitly drawn a distinction “between cases in which the merit of the claim is the issue and those where the coverage of the insurance policy is in question. In the first instance the allegation of the petition controls, and in the second the known or ascertainable facts are to be allowed to prevail.”1 Id. at 716.
The Corpus Christi court of appeals first recognized the exception in Gonzales v. American States Insurance Co. of Texas., 628 S.W.2d 184, 186 (Tex.App.-Corpus Christi 1982, no writ). The court in Gonzales did not find it necessary to apply the exception because it found the allegations within the petition were sufficient to give rise to the duty to defend, but recognized that courts may consider extrinsic evidence “where the petition does not allege facts sufficient for a determination of whether those facts, even if true, are covered by the policy....” Id. at 186. The Corpus Christi court would later employ the exception it articulated in Gonzales in State Farm Fire & Casualty Co. v. Wade, 827 S.W.2d 448, 452-53 (Tex.App.-Corpus [864]*864Christi 1992, writ denied). The Wade court found the exception applicable because “the facts in the petition do not establish whether there is even a potential for coverage.” Id. at 451. The underlying suit in Wade involved a wrongful-death claim arising out of a boating accident. Id. at 449-50. At issue was the applicability of a provision excluding coverage of accidents arising from use of the boat in a “business pursuit.” Id. at 450-51. The court, however, found it impossible within the eight corners to determine how the boat was used at the time of the accident. Id. at 451. But rather than find a duty to defend because facts potentially involving coverage were alleged in the petition, the court considered extrinsic evidence to determine how the boat was used. The court wrote: “It makes no sense to us ... to say that extrinsic evidence should not be admitted to show that an instrumentality (boat) was being used for a purpose explicitly excluded from coverage particularly, when doing so does not question the truth or falsity of any facts alleged in the underlying petition filed against the insured.” Id. at 458.
This court has not had occasion to consider a case in which the extrinsic evidence went solely to the issue of coverage.2 Most recently, we declined to apply the exception in a case in which the extrinsic evidence related to both coverage and liability, which we acknowledged then, and again today, is a combination the supreme court explicitly rejected in GuideOne. See D.R. Horton-Texas, Ltd. v. Market Int’l Ins. Co., 300 S.W.3d 773, 786 n. 19 (Tex.App.-Houston [14th Dist.] 2006), rev’d in part on other grounds, 300 S.W.3d 740 (Tex.2009).
B
In Boll, Cook, and Wade, the terms of a policy exclusion dictated there was no potential for coverage under the facts alleged in the petition. The merits of the underlying claim did not come into play because even if the allegations were true, a policy exclusion made coverage impossible. But Liberty Mutual does not urge the applicability of a policy exclusion. Instead, Liberty Mutual argues that it has no duty to defend because even if the facts alleged are true, Weingarten Management is a stranger to the policy. Although the circumstances giving rise to Liberty Mutual’s argument that the exception applies are different from the cases discussed above, the ultimate position is the same — an insurer should not be required to defend when extrinsic evidence can easily establish that the policy does not provide coverage even if all of the allegations in the plaintiffs petition are true.
The rationale behind the eight-corners rule is to require insurers to defend the insured against all claims, even those without merit. See Tri-Coastal Contractors, Inc. v. Hartford Underwriters Ins. Co., 981 S.W.2d 861, 863 (Tex.App.-Houston [1st Dist.] 1998, pet. denied). To the insured, a meritless claim still requires a defense. But the protection the eight-cor[865]*865ners rule provides exists for the benefit only of the insured. It is the insured who is entitled to trust that his insurer will defend him against all covered claims, meritorious or not. A stranger to the policy neither needs nor should expect this benefit.
Liberty Mutual does not argue that the claim brought against Weingarten Management is’without merit. Rather, Liberty Mutual argues that Weingarten Management is not an insured under the Norstan policy and, as a total stranger to the policy, is not entitled to a defense against any claim. Enforcing the rule under these circumstances does not further the policy underlying the eight-corners doctrine. This is a “pure coverage” question in which Liberty Mutual does not question the merits of the underlying third-party claim. See GuideOne, 197 S.W.3d at 308.
In light of the facts of this case, we are persuaded of the need for a very narrow exception to the eight-corners rule. The exception applies only when an insurer establishes by extrinsic evidence that a party seeking a defense is a stranger to the policy and could not be entitled to a defense under any set of facts. Under this exception, the extrinsic evidence must go strictly to an issue of coverage without contradicting any allegation. in the third-party claimant’s pleadings material to the merits of that underlying claim. See GuideOne, 197 S.W.3d at 310.
Although the supreme court declined to expressly recognize this exception in Gui-deOne, it was not presented with facts under which the exception would potentially apply. See id. at 308-09. GuideOne concerned an action against a church alleging that its youth minister had sexually assaulted the plaintiff. Id. at 307. GuideOne filed a declaratory-judgment action seeking a determination that it had no duty to defend because the youth minister left his job before the policy’s effective date. Id. The court held the extrinsic evidence GuideOne sought to introduce did not fit the exception because it “directly contradicts the plaintiffs allegations that the [cjhurch employed [the youth minister] during the relevant coverage period, an allegation material, at least in part, to the merits of the third-party claim.” Id. at 310. The court contrasted the case before it with Boll, in which the extrinsic evidence went solely to the coverage issue and did not contradict any allegation in the third-party claimant’s pleadings. Id. Although GuideOne argued it should not have to defend because it knew the youth minister was not in fact an employee of the church during the period in question, the court reiterated that the duty to defend required GuideOne to establish such facts in defense of its insured, rather than as an adversary in a declaratory-judgment action. Id. at 311 (citing. Heyden, 387 S.W.2d at 25).
There is a critical distinction between GuideOne and this case. In GuideOne, there was no question that the insurer had a policy with the church at the time of suit and that the insurer was therefore required to defend the church against at least some claims. Accordingly, the Gui-deOne court held the insurer owed a defense because the allegations of sexual misconduct were “potentially within coverage, even if the plaintiffs claims were false or fraudulent.” Id. Put another way, the facts alleged, if true, would support coverage. The insurer’s position in GuideOne simply was that the claim brought against its insured was meritless and could be easily disproved by showing the minister was no longer employed by the church when the policy became effective. But [866]*866although the minister may have left his job before the policy’s effective date, the church nonetheless had an effective policy at the time of suit that entitled it to a defense. In contrast, Liberty Mutual makes no comment on the merits of the underlying claim, but rather contends only that Weingarten Management simply could not be an insured as to any claim because it is a total stranger to the policy.
The case before us is much more similar to Blue Ridge Insurance Co. v. Hanover Insurance Co., 748 F.Supp. 470 (N.D.Tex.1990), than it is to GuideOne. In Blue Ridge, Southern Ionics, Inc., issued a company truck to one of its employees, Jimmy Beech, but Jimmy’s son, Scottie, was driving when the truck was involved in an injury accident. Id. at 471. The injured driver of the other vehicle sued Southern Ionics, Jimmy, and Scottie, and mistakenly alleged in his petition that Southern Ionics had granted Jimmy authority to allow Scottie to drive the truck. Id. Jimmy and Scottie’s insurer, Blue Ridge, assumed a defense but claimed Southern Ionics’s insurer, Hanover, also owed Jimmy and Scottie a defense as the “primary insurer.” Id. at 472. Hanover refused to defend on the grounds that the policy covered only the employer and persons driving a company vehicle with Southern Ionics’s permission. Id. Since it was undisputed that Scottie, not Jimmy, was driving the truck, and that under no circumstances was Scottie a permissive driver, Hanover argued it had no duty to defend. Id.
As in the case before us, Blue Ridge argued that the false allegation that Scottie was driving the truck with Southern Ionics’s permission, granted through Jimmy, gave rise to the duty to defend. Id. at 472-73. But the court held that the authorities Blue Ridge relied on “assume ... that the person claiming a right to a defense is an insured. Blue Ridge’s case authorities do not mean that a person who is not an insured under an insurance policy is to be treated as one for defense purposes just because of false allegations made by the damage suit plaintiff.”3 Id. at 473. The court accordingly held it could consider extrinsic evidence to determine that neither Jimmy nor Scottie was an insured under the Hanover policy. Id.
The “pure coverage” question the court faced in Blue Ridge did not involve the merits of the case because the insurer took the position that neither Jimmy nor Scottie were insureds, and therefore could not be considered permissive drivers in any case. Although it is true that any allegation, true or false, is sufficient to give rise to a duty to defend when the claim is potentially covered under the insured’s policy, the Blue Ridge court appropriately drew the distinction that “[t]he status of ‘insured’ is to be determined by trae facts, not false, fraudulent, or otherwise incorrect facts that might be alleged.” Id.
The appellants contend that because the policy named any of Norstari’s lessors as additional insureds, Liberty Mutual was obligated to defend anyone sued in that role, regardless of whether the party is actually a lessor. To support their position, they cite AccuFleet, Inc. v. Hartford Fire Insurance Co., 322 S.W.3d 264 (Tex.App.-Houston [1st Dist.] 2009, no pet.), and Liberty Mutual Insurance Co. v. Graham, 473 F.3d 596 (5th Cir.2006), as examples of cases in which courts adhered to the eight-[867]*867corners rule “if facts were plead[ed] that would quality the party as an insured.”
The appellants cite AccuFleet as a case where the court ignored extrinsic evidence and “specifically looked at the plaintiffs pleadings to determine whether a party was an additional insured, and therefore, owed a defense under the policy.” The underlying case involved an accident in which a Continental Airlines ground tug rear-ended an AccuFleet vehicle stopped at a stop sign on an airport tarmac. Accu-Fleet, 322 S.W.3d at 268. AccuFleet was a contractor providing services to Continental, and, pursuant to the terms of their contract, AccuFleet was required to name Continental as an additional insured under its liability policy. Id. An AccuFleet employee and passenger in the rear-ended vehicle sued AccuFleet and Continental for alleged injuries, both of which demanded a defense from AccuFleet’s insurer. Continental was not named in the policy, but claimed it was owed a defense under an “additional insured” provision that extended coverage to any parties AccuFleet was required by contract to include in its policy. Id. The insurer did not respond to either demand, and Continental eventually settled the claim. Id.
The court acknowledged that the contract required AccuFleet to name Continental as an insured, and that the policy’s “additional insured” provision included parties AccuFleet was required by contract to name as insureds. Id. at 271. The court interpreted the policy, however, to further require that an “additional insured” also meet the definition of “insured” from a separate section of the policy, a requirement Continental could not satisfy. Id. at 271-72. Therefore, the court was able to determine coverage did not exist for Continental under the facts alleged in the petition and the terms of the policy.4 See id.
AccuFleet stands for the unremarkable proposition that the eight-corners rule applies in the vast majority of cases. The appellants are correct that the court “specifically looked at the plaintiffs pleadings to determine whether a party was an additional insured, and therefore, owed a defense under the policy.” But this observation does not support the appellants’ position that the policy in this case required Liberty Mutual to defend any party sued in the role of lessor. AccuFleet would further the appellant’s position if the court held that, based on the information available in the pleadings and policy, the insurer owed Continental a defense even though extrinsic evidence could show that (1) there was no potential for coverage even if the pleaded facts were true, or (2) Continental was actually a total stranger to the policy. Instead, the Accu-Fleet court was able to resolve the question of coverage within the eight-corners rule, and in doing so it declined to hold the insurer owed Continental a defense because the eight corners told the court all it needed to know about Continental’s status as an insured.
Because AccuFleet did not recognize a duty to defend that would not have been recognized had the court been allowed to examine extrinsic evidence, it does not further the appellants’ argument. It certainly does not stand for the proposition that Liberty Mutual was obligated to defend any party sued in the role of Norstan’s lessor without regard to the party’s actual lessor status. That simply is not a reason[868]*868able reading of the policy. See Utica Nat’l Ins. Co. of Tex. v. Am. Indem. Co., 141 S.W.3d 198, 202 (Tex.2004) (holding the plain language of an insurance policy must be given effect when the parties’ intent may be discerned therefrom); see also Fiess v. State Farm Lloyds, 202 S.W.3d 744, 746 (Tex.2006) (holding if the policy language has only one reasonable interpretation, then it is not ambiguous and is construed as a matter of law). Liberty Mutual contracted to insure Norstan and its actual lessors, not to defend every party sued in the capacity as a lessor even though they are strangers to both the lease and the insurance policy.
Liberty Mutual Insurance Co. v. Graham is similarly distinguishable. Graham was involved in an accident in his company vehicle after he left a restaurant where he had consumed alcohol while celebrating his birthday. Graham, 473 F.3d at 597. He was sued for negligence and his employer was sued for negligently entrusting the vehicle to Graham. Id. at 598. The insurer brought an action for declaratory judgment asserting it was not required to defend Graham because his use of the vehicle was unauthorized and in 15 contravention of the employer’s vehicle-usage policy. Id. The insurer sought to introduce the employer’s vehicle-usage policy, which restricted use of vehicles to “company related business,” as well as evidence of Graham’s intoxication. Id. at 598-99. In' rejecting the insurer’s argument that the court should apply the exception, the court found “the complaint alleges facts sufficient to infer Graham was driving with [the employer’s] express or implied permission. Since the policy unambiguously covers permissive drivers, the duty to defend is invoked.” Id. at 603.
Ultimately, the Gratam court adhered to the eight-corners rule because the potential for coverage existed under the facts alleged by the underlying plaintiff. See id. at 603 & n. 25. If, in deciding whether the insurer owed a duty to defend, the court had explored whether Graham was actually intoxicated or had violated the vehicle-usage policy, it would have impermissibly delved into the merits. Furthermore, while the insurer in Graham might have been able to easily prove the claim merit-less upon mounting a defense, it did not argue that Graham was a total stranger to the policy. To the contrary, it was undisputed that, at least in some circumstances, Graham was a permissive user of the company truck.
The extrinsic evidence that might have been employed in Graham is utterly different from that which the trial court used in this case. The merits of the claim in the underlying case were not touched by the trial court’s inquiry in the coverage dispute. Graham is simply inapposite.
C
The appellants further argue that even if we apply an exception to the eight-corners rule, the extrinsic evidence in this case addresses not only the coverage question, but also the merits of the underlying claim, a combination the supreme court expressly rejected in GuideOne. See 197 S.W.3d at 310. The extrinsic evidence concerns the merits, the appellants argue, because the allegation that Weingarten Management was a lessor was “directly material” and “necessary” to show Johnson was a business invitee and owed a duty of care by Weingarten Management. The appellants further argue that because the terms of the lease would establish that Weingarten Management retained a right of control over the property, the allegation that Weingarten Management was a lessor [869]*869was material in establishing the scope of the duty owed to Johnson.
It is true that in a claim properly brought against an insurer by an actual insured, the existence and terms of a lease could be a significant factor in determining whether a landlord retained control over a leased premises. But here Liberty Mutual seeks to introduce evidence that Weingar-ten Management is not a lessor not to undermine the merits of the plaintiffs claim but to establish that Weingarten Management is a stranger to the policy. The appellants may see the lessor allegation as important to the merits of their case, but Liberty Mutual’s interest in contradicting it is confined to disputing Wein-garten Management’s status as an “insured.”
We also note that in each of the previous instances in which an exception to the eight-corners rule has been applied, the insurer sought to use a policy exclusion, combined with extrinsic evidence, to show that the policy excluded coverage even if the underlying allegations were true. The strict requirement that the proposed extrinsic evidence not contradict the plaintiffs underlying allegations sprang forth from the rationale behind the eight-corners rule, which requires insurers to defend their insureds against all covered claims regardless of merit. Allowing an insurer to admit extrinsic evidence contradicting a plaintiffs allegations to establish the applicability of a policy exclusion would circumvent the very reason for the eight-corners rule.
Therefore, under the narrow exception created by the facts in this case, we conclude that an insurer marking a party seeking a defense as a total stranger to the policy does not contradict allegations material to the underlying merits when it shows by extrinsic evidence that there are no facts that could be pleaded under which the party would be entitled to a defense.
D
The eight-corners rule prevents an insurer from refusing to defend an insured based on the lack of merit of the plaintiffs case. See Tri-Coastal Contractors, Inc., 981 S.W.2d at 863. But applying the eight-corners rule to pure-coverage questions does not advance this policy. Rather than provide a vital protection to the insured, the rule would impose on insurers the duty to defend parties who — by accident or otherwise — plead themselves into an insurance policy to which they were previously a stranger. If a contract does not exist, a duty to defend should not be allowed to spring into existence based on artful or inartful pleading.
Weingarten Management never contracted with Liberty Mutual to provide insurance, nor was it designated as an additional insured under the Liberty Mutual policy. Weingarten Management’s only claim to a defense from Liberty Mutual is a presumably accidental misidentifi-cation in the underlying petition that cited Weingarten Management as a lessor when it was not. But Liberty Mutual’s policy with Weingarten Investors requires it to defend actual lessors against any claim potentially within the policy. It does not require it to defend every entity mistakenly believed to be a lessor.
We hold the trial court did not improperly consider extrinsic evidence in granting summary judgment in Liberty Mutual’s favor and denying the appellants’ partial motion for summary judgment, motion for rehearing, motion for new trial, and motion for clarification. The appellants’ first issue is overruled.
Ill
The appellants argue in their second issue that in its consideration of ex[870]*870trinsic evidence the trial court erred in finding there was no fact issue as to whether Weingarten Management could be considered a lessor under the policy because the lease between Weingarten Investors and Fashion Cents required the latter to name Weingarten Management as an additional insured. The appellants urge us to interpret the word “lessor” in the policy’s “additional insured” endorsement to include any entity required by the lease to be named as an insured.
The appellants cite no authorities to support their argument other than the general proposition that courts should construe insurance policies broadly in favor of coverage and that if a policy is susceptible to more than one interpretation, the uncertainty must be resolved by adopting the construction most favorable to the insured. See State Farm Fire & Cas. Co. v. Reed, 873 S.W.2d 698, 699 (Tex.1993). The policy’s use of the word “lessor,” however, is not susceptible to multiple interpretations. It is not a reasonable interpretation to suggest that by using the word “lessor” the parties intended to incorporate unidentified and unlimited parties named in another contract as additionally insured parties. Appellants’ second issue is overruled.
IV
The appellants argue in their third issue that the trial court erred in granting summary judgment because there is a fact issue as to whether Liberty Mutual is estopped from denying Weingarten Management is a lessor. The appellants’ argument proceeds as follows: First, a certificate of insurance was issued by “Liberty Mutual Group” to both Weingar-ten Investors and Weingarten Management listing both a workers’ compensation policy and a general liability policy in a manner that the appellants contend made no distinction between the various Liberty entities providing the policies. Then, Liberty Insurance Company, Nor-stan’s workers’ compensation carrier, intervened in the underlying suit and adopted all of the plaintiffs allegations. Additionally, the appellants contend that subsequent correspondence did not distinguish between the entities. Therefore, appellants argue, Liberty Mutual Group represented to Weingarten Management that one carrier issued both policies and Liberty Mutual is estopped from arguing Weingarten Management’s lessor status because Liberty Insurance Company arguably adopted all of the plaintiffs allegations.
A judicial admission results when a party makes a statement of fact that conclusively disproves a right of recovery or defense currently asserted. See Richards v. Comm’n for Lawyer Discipline, 35 S.W.3d 243, 247 (Tex.App.-Houston [14th Dist.] 2000, no pet.) To constitute a judicial admission, the statement relied on must be (1) made in the course of a judicial proceeding; (2) contrary to an essential fact or defense asserted by the person making the admission; (3) deliberate, clear, and unequivocal; (4) related to a fact upon which judgment for the opposing party could be based; and (5) the enforcement of the admission would be consistent with public policy. Id.; see also Brown v. Lanier Worldwide, Inc., 124 S.W.3d 883, 900 (Tex.App.-Houston [14th Dist.] 2004, no pet.).
Assuming arguendo that all the above elements are fulfilled and that the statement constitutes a judicial admission on the part of Liberty Insurance Company, the appellants have cited no authority supporting their argument that this admission should be imputed to Liberty Mutual. Although the appellants present evidence that Liberty Mutual Group may have been less than clear in distinguishing between [871]*871its subsidiaries in a certificate of insurance and in correspondence, it has not directed us to any authority standing for the proposition that all the Liberty entities should therefore be treated as the same for purposes of determining whether one and therefore all made a judicial admission. As such, the argument is waived. See Tex.R.App. P. 38.1(i); Nguyen v. Kosnoski, 93 S.W.3d 186, 188 (Tex.App.-Houston [14th Dist.] 2002, no pet.) Appellants’ third issue is overruled.

Because we have overruled appellants’ first through third issues and held Liberty Mutual owed no duty to defend Weingar-ten, we do not reach appellants’ issues four through six. For the foregoing reasons, we affirm the trial court’s judgment.
