delivered the opinion of the Court.
Thе issue in this case is whether an insurer that posted a $29 million bond to supersede an adverse judgment against its insured may intervene in the insured’s appeal to assert a potentially dispositive issue that its insured abandoned in order to settle certain uninsured claims in another pending lawsuit. The court of appeals denied the insurer’s motion to intervene, and the insurer petitioned this. Court for mandamus relief. We hold that, under the unique facts presented, the court of appeals abused its discretion and, accordingly, conditionally grant the writ of mandamus.
I. Background
Sonat Exploration Company, 1 the owner of several gas wells in Louisiana, entered *721 into a Master Service Agreement (MSA) with Cudd Pressure Control, Inc. The agreement provided that Cudd would conduct “snubbing” operations, which involved forcing pipe into Sonat’s high-pressure wells during well-servicing procedures. The MSA provided that Cudd and Sonat would defend and indemnify each other for any claims brought by their respective employees. It also contained language that Sonat contends, in a separate lawsuit, required Cudd to provide insurance coverage to Sonat. 2 Lumbermens Mutual Casualty Company was Cudd’s excess-liability insurer at the time the parties entered into the MSA.
In 1998, an explosion occurred during snubbing operations at the Otto Cummings No. 2-Alt. well in Louisiana. The explosion killed seven people, including four Cudd employees, and severely injured three others. When Cudd’s employees and their families brought wrongful-death and personal-injury lawsuits in Texas against Cudd and Sonat, Cudd refused to indemnify Sonat and Lumbermens did not provide coverage to Sonat. As a result, Sonat filed a cross-claim against Cudd for indemnity, which was severed from the personal-injury suit and constitutes the underlying proceeding here. 3 Sonat also filed a separate breach-of-contract action against Lumbermens аnd Cudd, claiming that it was an additional insured under Cudd’s policy and, alternatively, that Cudd had breached a contractual obligation to procure insurance covering Sonat.
Sonat eventually settled the personal-injury suits, and the underlying indemnity action proceeded. One of the issues presented was whether Texas or Louisiana law applied to the indemnity claim. The parties contended the issue was potentially dispositive because under Louisiana statutory law the MSA’s indemnity provision was void, while under Texas law it was valid. The trial court granted partial summary judgment in Sonat’s fаvor, holding that Texas law applied and Sonat was entitled to indemnity for the damages it had paid to settle the Cudd employees’ lawsuits. 4 The case went to trial on damages only, and the jury returned a $20.7 million verdict in Sonat’s favor upon which the trial court rendered judgment. Cudd filed a notice of appeal from the trial court’s judgment and from “all other ruling[s], orders and judgments rendered against Cudd in this matter.” Lumbermens posted the $29 million appellate security, and Sonat has not offered to release Lumber-mens from that obligation.
After Cudd perfected its appeal in the indemnity casе underlying this mandamus *722 proceeding, Cudd and Sonat entered into a Rule 11 Agreement in the breach-of-contract suit pursuant to which Cudd agreed to forgo any further challenge to the trial court’s choice-of-law ruling, and Sonat agreed to nonsuit its pending breach-of-contract claim against Cudd. Two days later, Cudd filed its appellate brief in the indemnity appeal, which did not raise the choice-of-law issue. Sonat then filed a motion to dismiss with prejudice its breaeh-of-contract claim pursuant to the Rule 11 Agreement, which the trial court granted. Ten weeks after Cudd filed its apрellate brief, Lumbermens sought leave to intervene in the court of appeals in order to preserve the choice-of-law issue. The court of appeals denied Lumbermens’ motion, and the appeal remains pending in that court.
II. Standard of Review
At the outset, we note that the issue presented has been somewhat miscast. Lumbermens contends the equitable virtual-representation doctrine entitles it to “intervene” on appeal to assert the choice-of-law issue that its insured abandoned. Under that doctrine, a litigant is deemed to be a party if it will be bound by the judgmеnt, its privity of interest appears from the record, and there is an identity of interest between the litigant and a named party to the judgment.
Motor Vehicle Bd. of Tex. v. El Paso Indep. Auto. Dealers Ass’n,
Given the relatively unique procedural posture of this case, it is not surprising that we have not articulated the standard of review by which to measure the court of appeals’ denial of Lumber-mens’ intervention. The parties here assume that an abuse-of-discretion standard governs our review, and we agree. When reviewing a trial court’s decision to strike a party’s intervention under Rule 60 of the Rules of Civil Procedure,
5
we apply an abuse-of-discretion standard.
Guar. Fed. Sav. Bank v. Horseshoe Operating Co.,
III. Parties’ Arguments
Lumbermens contends the court of appeals abused its discretion in rejecting Lumbermens’ intervention because, as Cudd’s insurer and the party that posted the appellate security, Lumbermens is bound by the judgment in the case. Accordingly, Lumbermens claims it is entitled to appeal the trial court’s choice-of-law ruling under the doctrine of virtual representation.
See City of San Benito,
On the other hand, Sonat claims the court of appeals did not abuse its discretion in denying Lumbermens’ intervention. According to Sonat, the virtual-representation doctrine does not entitle Lumbermens to participate in the appeal because there must be an identity of interests between the party claiming the doctrine’s benefit (Lumbermens) and a party to the judgment (Cudd), and Lumbermens has expressly acknowledged that its and Cudd’s interests have diverged. Sonat further contends Lumbermens has no due-process stake in the appellate proceedings because, if Cudd does not prevail in its appeal, Lumbermens can invoke a noncooperation clause in Cudd’s policy to deny coverage and ultimately avoid the judgment. Sonat also contends that, if Lumbermens desired to intervene, it had to do so before the trial court rendered a final judgment and any attemрt to intervene on appeal was untimely. And even if intervention on appeal was permissible, Sonat maintains, Lumber-mens waited too long to avail itself of that procedure by failing to seek leave until after all the appellate briefing was completed. Finally, Sonat asserts that allowing intervention would be bad public policy because it could complicate virtually all appellate proceedings involving liability insurance by enabling insurers to second-guess their insureds’ decisions regarding the appropriate issues to raise on appeal. Such a course, contends Sonat, would be inconsistent with Texas’s status as a state that generally does not permit insurers to join in tort actions against their insureds. See, e.g., TEX. R. CIV. P. 38(c) (prohibiting joinder of a liability or indemnity insurance company unless the insurer is liable by statute or contract to the injured person); TEX. R. CIV. P. 51(b) (same).
IV. Virtual-Representation Requirements
Generally, only parties of record may appeal a trial court’s judgment.
El Paso Indep. Auto. Dealers Ass’n,
In this case, Sonat contends Lumber-mens may not invoke the virtual-representation doctrine’s benefit because Lumber-mens has acknowledged that its interests and Cudd’s have diverged, in that Cudd no longer wishes to contest the trial court’s choice-of-law decision. Lumbermens responds that its and Cudd’s ultimate aim— to reverse the underlying judgment — remains the same. We agree with Lumber-mens. The identity of interest upon which the virtual-representation doctrine in this case turns relates to protecting the funds that the underlying judgment puts at risk.
See Huizar,
In any event, our decisions in
El Paso Independent Automobile Dealers Ass’n
and
City of San Benito
illustrate that the position of one who relies on the virtual-representation doctrine to appeal and the party that formerly represented its interests will have often, if not always, diverged to some extent by the time the beneficiary of the doctrine invokes it. In
El Paso Automobile Dealers Ass’n,
for example, the interests of the Attorney General and the Motor Vehicle Board in defending the Blue Laws’ constitutionality were initially protected by the local attorneys. Not until those attorneys abandoned their defense of the statute did the need arise fоr the Attorney General and the Board to directly participate in order to protect their interests. Despite the diverging positions of the state and local entities regarding the Blue Law’s constitutionality, we held that the Attorney General and the Board were entitled to appeal.
Sonat contends Lumbermens should not be allowed to invoke the virtual-representation doctrine because it can ultimately avoid coverage for the judgment by invoking a noncooperation clause in Cudd’s policy. But irrespective of any potential coverage dispute between Lumbermens and Cudd, Lumbermens has pledged $29 million to secure the judgment in Sonat’s favor. Even if Lumbermens could eventually recoup the amоunt it has pledged through a potential coverage suit against Cudd, its obligation to pay the underlying judgment to Sonat is immediate and binding in the event Cudd’s appeal is unsuccessful.
In this case, neither the fact that Cudd’s and Lumbermens’ interests in pursuing appeal of the choice-of-law issue have diverged, nor the possibility that Lumber-mens could later assert a noncooperation defense against Cudd, prevent Lumber-mens from invoking the virtual-representation doctrine. But because the doctrine is equitable, we must determine whether other considerations weigh against applying the doсtrine to allow Lumbermens’ intervention on appeal.
See Huizar,
V. Timing Considerations
A. Post-judgment Action
Sonat contends that, even if Lumbermens had a right to participate on appeal, the court of appeals did not abuse its discretion in denying Lumbermens’ intervention because Lumbermens only attempted to do so after the trial court’s judgment became final. Ordinarily, a trial court does not abuse its discretion by denying a motion to intervene after the court has rendered a final judgment.
Comal County Rural High Sch. Dist. No. 705 v. Nelson,
B. Timeliness
Sonat argues that Lumbermens is not entitled to intervene because it did not attempt to do so until after Cudd filed its reply brief in the court of appeals, ten weeks after Sonat nonsuited its breach-of-contract claims and Cudd failed to raise the choice-of-law issue in its initial appellate brief. We have never articulated a particular standard for evaluating the timeliness of a virtually-represented party’s effort to invoke appellate rights. But we find useful the test that the Fifth Circuit has recently articulated for evaluating the timeliness of a motion to intervene as of right under Rule 24(a)(2) of the Federal Rules of Civil Procedure.
7
Considerations under that test are (1) the length of time during which the would-be intervenor should have known of its interest in the case before attempting to intervene; (2) the extent of prejudice that the existing parties may suffer as a result of the would-be intervenor’s failure to apply for intervention as soon as it actually knew or should have known of its interest in the case; (3) the extent of prejudice the would-be intervenor would suffer if intervention is denied; and (4) the existence of unusual circumstances militating either for or against a determination that the application is timely.
Ross,
The first factor “‘focuses on the time lapse between the applicant’s receipt of actual or constructive knowledge of his interest in the litigation and the filing of his motion for intervention.’ ”
Id.
at 754 (quoting
Edwards v. City of Houston,
In this case, ten weeks elapsed between the time Lumbermens became aware that Cudd would not pursue the choice-of-law ruling and the time Lumbermens filed its motion to intervene. Lumbermens explains this delay by pointing to the novel posture of this case and the uncertainty created by the lack of any specific rule providing for intervention on appeal. In evaluating the reasonableness of an appellant’s explanation of delay in perfecting an appeal, we have given weight to the fact that the underlying procedural rules were unclear.
See Hone v. Hanafin,
The second factor in the Fifth Circuit’s timeliness test is the extent of prejudice that the existing parties may suffer as a result of the applicant’s failure to apply for intervention at an earlier time; this factor “ ⅛ concerned only with the prejudice caused by the appliсants’ delay, not that prejudice which may result if intervention is allowed.’ ”
Ross,
The third factor the Fifth Circuit considers is the extent of prejudice the applicant would suffer if intervention is not permitted.
Ross,
The fourth factor the Fifth Circuit considers is “the existence of unusual circumstances militating either fоr or against a determination that the application is timely.”
Ross,
In light of the novel posture of this case, the extent of likely prejudice to Lumber-mens if it is not allowed to raise the choice-of-law issue its insured abandoned, and the unlikelihood of prejudice to Sonat resulting from the timing of Lumbermens’ effort to invoke appellate rights, we conclude that the timing of Lumbermens’ motion does not prevent its intervention.
C. Public Policy
Sonat argues that if Lumbermens is permitted to appeal in this case, then all insurers, indemnitors, and other similarly-situated parties will be entitled to intervene on appeal, potentially interfering with insureds’ appellate strategy or raising issues contrary to their insureds’ interests or colluding with their insureds to expand briefing schedules or page limitations. We note that analogous concerns arguably exist when an insurer intervenes in the trial court, and Sonat seеms to agree that Lum-bermens would have been entitled to intervene in the trial court if Cudd had opted not to pursue the choice-of-law issue there. Nevertheless, we agree that every disagreement between an insured and its liability insurer would not justify separate appeals. As we recently acknowledged, the insurance policy determines whether an insurer or its insured has the right to control litigation, a contract right that would be defeated if every disagreement between the two justified each in filing its own appeal.
See Northern County Mut. Ins. Co. v. Davalos,
YI. Conclusion
We hold that under the unusual circumstances this case presents, Lumbermens is entitled to invoke the virtual-representation doctrine to raise on appeal the choice-of-law issue its insured abandoned in order to settle uninsured claims in another suit, аnd the court of appeals abused its discretion in holding otherwise. Accordingly, we conditionally grant the writ of mandamus and direct the court of appeals to permit Lumbermens’ participation to contest the trial court’s choice-of-law ruling. The writ will issue only if the court fails to do so.
Notes
. Sonat's successor-in-interest is El Paso Production Company, but we will refer to the company in this opinion as Sonat.
. Sonat entered into a similar agreement with Brooks Well Servicing, Inc., which performed well-servicing operations for Sonat. Brooks was a party to the underlying lawsuit; howеver, Brooks is not a party to this mandamus proceeding, and we need not discuss Brooks’s involvement at length to resolve the narrow issue presented. We have accordingly omitted much of the background information involving Brooks.
. In addition to the Texas indemnity action, two similar declaratory-judgment actions involving the MSAs and their insurance and indemnity provisions were brought in Louisiana, one of which eventually settled and was dismissed. For the same reason we omitted information about Brooks’s involvement in this litigation, we have also omitted procedural history of the two Louisiana cases that is not material to the issue presented here.
.In the pending Louisiana action brought by Brooks Well Servicing, Inc., the district court concluded, after dismissing Cudd from the suit, that Louisiana law applied to the MSA between Sonat and Brooks and that the insurance and indemnity provisions in the Agreement were void. The Louisiana court of appeals subsequently reinstated the case against Cudd, but there is no decision from a Louisiana appellate court on the choice-of-law issue as to either the Sonat-Brooks MSA or the Sonat-Cudd MSA.
. Under Rule 60, "[a]ny party may intervene by filing a рleading, subject to being stricken ... for sufficient cause ...TEX. R. CIV. P. 60.
. Although Justice Gonzalez and Chief Justice Hill expressed their view that the insurer had a right to continue the appeal that its insured abandoned, a majority of the Court did not reach the question after deciding that the insurer had already voluntarily paid the policy proceeds to the plaintiff.
Huizar,
. The federal rule mandates that intervention be allowed if an applicant timely seeks to intervene and the party “claims an interest relating to the property or transaction which is the subject of [an] action and the applicant is so situated that the disposition of the action may as a practical matter impair or impede the applicant's ability to protect that interest unless the applicant’s interest is adequately represented by existing parties.” FED. R. CIV. P. 24(a). The Fifth Circuit’s timeliness test seems appropriate here because Lumber-mens will be bound by any judgment against Cudd, and Cudd no longer represents its interest in pursuing the choice-of-law issue.
. We note, however, that the trial court has ruled that Sonat is in fact an additional insured under Cudd's policy with Lumbermens. As we understand the proceedings in the breach-of-contract case, that ruling, if it remains undisturbed, would essentially moot Sonat's contractual claims against Cudd and result in no harm to Sonat from the dismissal.
