A policy limits demand letter in Illinois is a formal written demand asking the at-fault driver’s insurer to pay the full available policy limits in exchange for a release of the insured. When liability is clear and the injured person’s damages exceed the policy, this type of demand is a critical tool. It places the insurer in a documented position where accepting means resolving the claim and rejecting means exposing its insured — and potentially itself — to significant financial consequences.

Why Policy Limits Demands Matter Under Illinois Law
Illinois law imposes an affirmative duty on liability insurers to protect their policyholders from excess judgments. The Illinois Supreme Court addressed this obligation directly in Haddick v. Valor Insurance Co., 198 Ill. 2d 409 (2001). In that case, the court held that an insurer has a duty to settle within policy limits when the claimant’s damages clearly exceed those limits and a reasonable opportunity to settle exists. Failure to do so can expose the insurer to a claim for the full amount of any excess judgment — even an amount above the policy — on the theory that the insurer acted in bad faith by prioritizing its own financial interests over those of its insured.
This exposure is sometimes called the "bad-faith setup" in litigation practice. The mechanics work as follows: the injured party sends a time-limited demand for policy limits with supporting documentation of liability and damages. If the insurer declines and the case proceeds to trial, and if the jury returns a verdict above the policy limits, the insured is personally liable for the excess. The insured can then bring a bad-faith action against the insurer for failing to settle when it had the chance. The time-limited demand creates a record demonstrating that the opportunity to settle within limits existed and was rejected.
Confirming Policy Limits Before Sending the Demand
Before drafting a policy limits demand, you need to know what limits are available. Under 215 ILCS 5/143.24b, an injured person may submit a written request to the at-fault driver’s insurer for disclosure of applicable policy limits. The request must be accompanied by documentation of the injury — typically a copy of the police report, medical records, or a combination of both. The insurer is required to disclose the limits within a reasonable time. Confirming limits in writing before the demand goes out ensures the demand is calibrated to the correct number and creates a clear record of what the insurer knew and when.
What a Well-Constructed Demand Includes
A policy limits demand is not simply a letter asking for money. To be effective and to serve its function in establishing the insurer’s excess exposure, it needs to include several components. First, it must clearly state that the demand is for the full available policy limits. Second, it must include a reasonable deadline for acceptance — typically thirty days, though shorter timeframes may be appropriate in cases of extreme urgency. Third, it must be accompanied by documentation sufficient to allow the insurer to evaluate the claim: medical records and bills establishing the nature and cost of treatment, evidence of lost wages if applicable, the police or crash report, and any other materials bearing on liability and causation.
The demand should also state the conditions of acceptance — typically a full and final release of the at-fault driver in exchange for the policy limits payment. If there are multiple parties or multiple policies, the demand must address how each applies. For broader insurance claims guidance on how these interactions work, documenting each step of the process in writing is essential throughout.
Illinois Regulations on Timely Claims Handling
The insurer’s obligation to respond promptly to a policy limits demand is supported by 215 ILCS 5/154.6, which identifies unfair claims practices that Illinois law prohibits when they reflect a general business practice. Among the listed prohibitions is failing to promptly settle claims where liability is reasonably clear. An insurer that receives a time-limited demand supported by clear liability evidence and documented damages has an obligation to evaluate that demand seriously and respond within a reasonable time. Delay without documented justification can itself become part of a bad-faith narrative if the matter proceeds to litigation.
The Administrative Code standards under 50 Ill. Adm. Code Part 919 reinforce these requirements by establishing specific investigation timelines. An insurer that has not completed its investigation when a policy limits demand arrives may still be expected to make a coverage decision within the demand period if the supporting documentation provides a sufficient basis for evaluation.
When the Insurer Accepts — and When It Does Not
If the insurer accepts within the deadline, the claim resolves for policy limits. That outcome may be the best available result if the at-fault driver has no significant personal assets and no additional layers of coverage exist. It is worth verifying, before accepting, whether umbrella or excess coverage is available above the primary policy — because once a release is signed for primary limits without preserving rights against umbrella coverage, those rights may be lost.
If the insurer rejects the demand or fails to respond within the deadline, the demand has served a different function: it has created a documented record of the insurer’s decision to decline a reasonable opportunity to settle. That record becomes relevant if the case proceeds to trial and results in an excess verdict. Whether the insurer’s conduct rises to the level of bad faith under Illinois law is a fact-specific analysis, and the outcome of any such claim depends on the specific circumstances of the case. No attorney can guarantee any particular result.
Why Attorney Involvement Is Essential at This Stage
A policy limits demand is a legal document with significant consequences. An error in the demand’s terms, a deadline that is unreasonably short, missing documentation, or an imprecise release condition can undermine the demand’s effectiveness or create problems if the case later proceeds to litigation or an excess judgment claim. Illinois courts evaluate whether a demand was reasonable based on the totality of circumstances, including how well the documentation supported the claimed damages at the time the demand was made.
Retained legal counsel can also evaluate whether policy limits are the right endpoint given your damages, whether additional coverage layers exist, and whether the timing of the demand makes strategic sense given where the insurer’s investigation stands. These are judgment calls that depend on the specific facts of your case and cannot be made based on general information alone.
