Introduction
In United Servs. Auto. Ass'n v. Wenzell, 2026 CO 25, the Colorado Supreme Court addressed two important questions in first-party insurance litigation: when Colorado’s failure-to-cooperate statute applies, and when an excess underinsured-motorist (“UIM”) insurer must begin responding to a claim.
The respondent, Anthony Wenzell, was injured in a 2017 rear-end collision after having suffered serious injuries in a prior 2014 accident. He pursued UIM benefits from State Farm Mutual Automobile Insurance Company, his primary UIM insurer, and United Services Automobile Association (“USAA”), an excess UIM insurer under a family policy. Both insurers sought medical-record authorizations to distinguish damages from the 2017 accident from those related to the 2014 accident. They asserted that Wenzell failed to provide adequate releases.
The court held that section 10-3-1118’s notice-and-cure procedures apply only to defenses arising from a policy’s general cooperation clause, not to separate defenses based on failure to satisfy specifically enumerated conditions precedent. It also held that an excess UIM exhaustion clause may be enforced, but exhaustion depends on undisputed damages exceeding all underlying policy limits—not on actual payment of those limits by underlying insurers.

Statutory Interpretation and Common-Law Background
The court relied on Apodaca v. Allstate Ins. Co. for the rule that interpretation of Colorado’s insurance code is reviewed de novo, and on Bailey v. Lincoln Gen. Ins. Co. for de novo review of insurance contracts and public-policy challenges to policy provisions.
Skillett v. Allstate Fire &Cas. Ins. Co. supplied the basic interpretive framework: courts seek to effectuate legislative intent, beginning with plain language. Vigil v. Franklin, United States v. Hansen, and Beach v. Beach were central to the majority’s conclusion that the legislature is presumed to know existing common law and does not abrogate it without clear expression.
The majority used Cowen v. People to justify consulting dictionary definitions of “cooperate,” but ultimately found the term ambiguous because it could bear either a broad ordinary meaning or a narrower technical meaning rooted in insurance policies and common law.
Failure to Cooperate Versus Conditions Precedent
State Farm Mut. Auto. Ins. Co. v. Brekke played a key role. The majority read it as distinguishing a general duty to cooperate from specific policy duties that operate as conditions precedent to coverage. The court also relied on Soicher v. State Farm Mut. Auto. Ins. Co. for the rule that a true failure-to-cooperate defense requires the insurer to show it was materially and substantially disadvantaged.
State Farm Mut. Auto. Ins. Co. v. Goddard and Ahmadi v. Allstate Ins. Co. reinforced the distinction between cooperation clauses and separate contractual conditions. Finally, Jensen v. Am. Fam. Mut. Ins. Co. supported the consequence of the holding: failure to comply with a condition precedent bars recovery under the policy.
The dissent, by contrast, invoked Farmers Auto. Inter-Insurance Exch. v. Konugres, State Farm Mut. Auto. Ins. Co. v. Secrist, Cribari v. Allstate Fire &Cas. Ins. Co., and Polland v. State Farm Mut. Auto. Ins. Co. to show that Colorado courts have not consistently drawn a clean line between general cooperation duties and specific policy obligations. In the dissent’s view, that inconsistency was exactly why the legislature enacted section 1118.
Excess UIM Exhaustion
On UIM exhaustion, the court cited Shelter Mut. Ins. Co. v. Mid-Century Ins. Co. for the principle that insurers may use “other insurance” clauses to define priority among multiple policies.
The court discussed Apodaca v. Allstate Ins. Co. and Pub. Serv. Co. of Colo. v. Wallis &Cos., noting that although those cases referenced exhaustion, they did not define exhaustion in the excess UIM context.
The division below had relied on Tubbs v. Farmers Insurance Exchange and Ligotti v. Allstate Fire &Casualty Insurance Co.. The Supreme Court agreed with the core logic of Ligotti v. Allstate Fire &Casualty Insurance Co.: an excess UIM insurer may not wait for actual payment of underlying limits if the insured has undisputed damages exceeding those limits.
The court compared two national approaches: the undisputed-damages approach, illustrated by Waste Mgmt. of Minn., Inc. v. Transcon. Ins. Co., and the payment-limit approach, illustrated by Citigroup Inc. v. Fed. Ins. Co.. Colorado adopted the undisputed-damages approach for excess UIM claims.
Meyer v. State Farm Mut. Auto. Ins. Co., Schlessinger v. Schlessinger ex rel. Schlessinger, and Jordan v. Safeco Ins. Co. of Am., Inc. informed the court’s public-policy analysis: insurance provisions cannot dilute, condition, or limit statutorily mandated coverage. State Farm Mut. Auto. Ins. Co. v. Fisher clarified that statutory bad-faith liability turns on delay or denial of undisputed covered benefits. Westin Operator, LLC v. Groh supplied the summary-judgment standard.
Legal Reasoning
1. Section 10-3-1118 Applies Only to General Cooperation-Clause Defenses
The majority framed the statutory question as whether “failure-to-cooperate defense” covers all insurer defenses based on an insured’s failure to comply with policy obligations, or only defenses based on a general cooperation clause.
Because Colorado common law had distinguished general cooperation duties from specific conditions precedent, the court held that section 1118 did not erase that distinction. The statute did not clearly state that it was abrogating common law. Therefore, its notice-and-cure procedures apply only when the insurer invokes the general cooperation clause.
Applied here, the medical-release provisions were specific policy obligations. The insurers’ defense was therefore treated as a condition-precedent defense, not a statutory failure-to-cooperate defense. As a result, the insurers were not required to comply with section 1118 before relying on Wenzell’s failure to provide adequate medical authorizations.
2. Excess UIM Exhaustion Turns on Undisputed Damages, Not Actual Payment
The court then addressed USAA’s argument that, as an excess UIM insurer, it owed nothing until State Farm actually paid its primary UIM policy limits. The court rejected that payment-limit theory.
The court reasoned that UIM coverage is governed by Colorado statute and public policy. Allowing an excess insurer to wait for actual payment by the primary insurer would improperly condition excess coverage on another insurer’s conduct. Instead, exhaustion occurs when the insured demonstrates undisputed damages exceeding the combined limits of all underlying coverage.
This rule preserves exhaustion clauses while preventing them from operating as disguised setoffs or barriers to statutorily required UIM coverage.
Impact
This decision has significant consequences for Colorado insurance litigation.
-
For insurers: Insurers may distinguish between a general cooperation defense and a condition-precedent defense. But the majority cautioned that insurers may not use novel or unduly onerous conditions precedent to evade section 1118 in bad faith.
-
For policyholders: Insureds must pay close attention to specific policy duties, such as providing medical authorizations, records, or other documentation. Failure to comply may bar coverage without the statutory notice-and-cure protection of section 1118.
-
For excess UIM carriers: They cannot refuse to evaluate a claim merely because the primary insurer has not paid its limits. If damages above underlying limits are undisputed, excess obligations may be triggered.
-
For future litigation: Courts will likely see disputes over whether a policy provision is a general cooperation clause or a specific condition precedent, and whether claimed damages are truly “undisputed.”
