Insurance Bad-Faith Claims: How State Law Defines It and What Triggers Liability (2026)

Rate Authority’s framework for insurance bad faith identifies this as one of the most consequential and most misunderstood doctrines in U.S. insurance law. Bad faith is not simply a claim that went poorly — it is a legally defined failure by a carrier to fulfill its implied duty of good faith and fair dealing, a duty that exists in every insurance contract as a matter of common law and, in most states, by statute. The doctrine creates liability that can exceed the policy limits themselves, which is why it sits at the center of high-stakes claims disputes. Per Rate Authority’s bad-faith liability framework, three structural branches of conduct generate the overwhelming majority of bad-faith exposure: unreasonable delay in claim handling, unreasonable denial of covered claims, and failure to settle a third-party claim within policy limits when a reasonable opportunity existed.

The Three Branches of Bad-Faith Liability

Unreasonable delay occurs when a carrier fails to investigate, acknowledge, or pay a covered claim within a timeframe that state statute or regulatory standard defines as reasonable. The NAIC’s model Unfair Claims Settlement Practices Act — adopted in substantially similar form by most states — requires acknowledgment of a claim within ten to fifteen days of notice, and prompt investigation and payment thereafter. When carriers allow claims to languish without documented justification, the delay itself becomes the conduct at issue, independent of whether the underlying claim is ultimately paid.

Unreasonable denial is the second branch. A denial is not automatically bad faith simply because a court later finds the claim covered — the carrier must have lacked a reasonable basis for the denial, and in most jurisdictions must have known it lacked that basis or acted in reckless disregard of it. This dual requirement (the “objective-subjective” standard, as codified in states including California under Insurance Code § 790.03 and its Brandt line of case law) means that a genuinely disputed coverage question, handled transparently, rarely qualifies as bad faith. A denial issued without investigation, or one that ignores controlling policy language, is structurally different and meets the threshold more readily.

Failure to settle within limits is the third branch, and it is exclusively a third-party doctrine. When a claimant presents a settlement demand within the insured’s policy limits and the carrier refuses to accept it — exposing the insured to an excess judgment — the carrier may owe the full excess judgment to the insured, regardless of the policy cap. The structural logic: the carrier controls the defense and settlement process, and the insured cannot independently resolve the claim. States including Florida (§ 624.155, Fla. Stat.) and Texas (Tex. Ins. Code § 541) have codified this exposure explicitly.

First-Party vs. Third-Party Bad Faith: A Structural Distinction

The first-party / third-party distinction is not a technicality — it reshapes both the legal elements and the remedies available. First-party bad faith arises between the policyholder and their own carrier: a homeowner whose insurer unreasonably denies a property claim, or an auto insured whose underinsured motorist claim is stonewalled. Third-party bad faith arises when a liability carrier’s failure to settle on behalf of its insured exposes that insured to personal financial liability above the policy limits.

Most states recognize both branches, but the procedural path differs significantly. In first-party bad faith, the policyholder is the direct plaintiff. In third-party bad faith, the insured — now holding an excess judgment — typically assigns their bad-faith claim against the carrier to the injured claimant, or pursues it directly. Some states, including California and Florida, have developed robust statutory frameworks for both branches. Others, particularly in the Southeast and Mountain West, recognize only a common-law tort theory, which narrows the damages available and raises the evidentiary burden. The NAIC’s market conduct model acts govern carrier conduct in all states, but private litigation rights vary substantially by jurisdiction.

Prima Facie Elements and What Plaintiffs Must Show

Rate Authority’s analysis of state statutes and model law identifies four prima facie elements that most jurisdictions require to establish bad faith: (1) the existence of an insurance contract; (2) the insurer’s receipt of a claim or demand under that contract; (3) conduct by the insurer that was unreasonable — meaning no reasonable insurer in the same position would have acted identically; and (4) that the unreasonable conduct caused cognizable harm to the insured. In states with statutory bad-faith causes of action (California, Florida, Texas, Washington), a fifth element is commonly required: notice to the carrier of the alleged violation before suit, giving the carrier an opportunity to cure. Florida’s § 624.155 civil remedy notice requirement is among the most formalized versions of this cure window — carriers that remedy the conduct within sixty days can defeat the statutory claim entirely.

Punitive damages are available in bad-faith cases in most states, but the evidentiary bar is higher than for compensatory damages — typically requiring proof of intentional misconduct or conscious disregard of known rights. Because punitive exposure can be multiples of the compensatory award, carrier claims operations treat the bad-faith threshold as a primary compliance risk, not merely a litigation posture.

The DOI Complaint Mechanism: The Parallel Regulatory Track

Private bad-faith litigation runs parallel to, but does not displace, the administrative enforcement track. Every state Department of Insurance operates a consumer complaint intake process through which policyholders can report alleged Unfair Claims Settlement Practices Act violations. The DOI does not resolve individual claim disputes or award damages — its authority is market conduct enforcement: examining carrier claims practices, issuing cease-and-desist orders, and levying civil fines. Complaint data is published in aggregate by the NAIC through its Consumer Insurance Search portal and by individual DOIs in annual market conduct examination reports.

The DOI track matters because it generates a regulatory record that can be relevant in subsequent private litigation, and because carriers facing elevated complaint ratios in a state draw market conduct examinations that expose systemic practices across thousands of claims — not just the individual case. Rate Authority’s analysis of NAIC market conduct data consistently shows that carriers with elevated complaint ratios in personal lines face disproportionate examination frequency.
