When a plaintiff offers to settle a covered claim within the primary policy's limits, the insurer that controls the defense faces a conflict: settling costs the insurer money now, while trying the case risks nothing beyond the policy limits for the insurer but exposes the insured to a judgment far above them. Failure-to-settle liability exists to police that conflict. If the insurer unreasonably refuses a settlement demand it could and should have accepted, and the case then goes to verdict for more than the limits, the insurer can become liable for the entire excess judgment -- not just the policy limits it originally promised to pay.

This doctrine is narrower than a general bad-faith claims-handling theory. It attaches to one specific decision point: an insurer that had the opportunity to settle within limits and did not take it. Courts in most jurisdictions evaluate that decision from the standpoint of a reasonable insurer giving the insured's own financial exposure equal consideration to the insurer's own interest, not merely asking whether the insurer's litigation judgment was defensible in hindsight.

A plaintiff (typically the insured, or the judgment creditor standing in the insured's shoes after an assignment) generally must show: (1) a covered claim existed under the policy; (2) a settlement demand within policy limits was made and was reasonable given the likely liability and damages exposure; (3) the insurer had the opportunity to settle within that window and failed to do so; and (4) a judgment was ultimately entered against the insured in excess of the policy limits.

Most jurisdictions apply some version of an 'equal consideration' standard: the insurer must weigh the insured's exposure to an excess judgment on the same footing as its own financial interest in avoiding or minimizing payment. A minority of jurisdictions frame the standard closer to ordinary negligence, asking only whether the insurer acted as a reasonably prudent insurer without personal liability exposure would have acted.

Losing at trial is not, by itself, bad faith. An insurer that reasonably investigated the claim, reasonably assessed liability and damages exposure, and reasonably concluded the demand was too high or the claim too weak to warrant settling within limits has not acted in bad faith even if the jury later disagrees. The doctrine targets the insurer's decision-making process at the time the demand was live, not the outcome the jury eventually reaches.

Because of that timing focus, the record of what the insurer knew and did during the settlement window -- the demand letter, the claims file, any deadline attached to the offer, the insurer's own exposure evaluation -- becomes the central battleground, far more than the trial record itself.

Plaintiffs build the claim from the insurer's claims file: how the adjuster valued the case, whether defense counsel flagged excess exposure, whether the demand had a firm deadline the insurer let lapse, and whether comparable claims were routinely settled at similar values. Expert testimony on claims-handling standards often supports the reasonableness showing.

Insurers defend by showing a genuine, documented, good-faith dispute over liability or damages existed at the time of the demand -- disputed causation, contested damages valuation, or a demand that was itself unreasonable or impossible to accept on its stated terms (an unreasonably short deadline, an incomplete release, or a demand exceeding available limits across multiple claimants). A well-documented, contemporaneous evaluation is the insurer's strongest evidence that its refusal was reasonable rather than self-interested.

Plaintiffs' counsel often manufacture the predicate for this claim deliberately: a time-limited settlement demand within limits, sent early and documented carefully, creates the record needed later if the insurer declines and the case goes to a large verdict. The demand itself becomes a strategic instrument, not just a settlement overture.

In Juricratic terms, this doctrine is a claim path layered on top of the underlying tort exposure model -- the insurer's settle-or-litigate decision becomes a decision node whose modeled outcome depends on dials for liability strength, damages range, and demand reasonableness. War-gaming the excess-exposure branch alongside the underlying claim shows how the modeled bad-faith exposure grows as the settlement window narrows. These are simulation inputs, not predictions.
