RE: SETTLEMENT DEMAND — MOTOR VEHICLE COLLISION
Our Client: [________________________________]
Date of Loss: [__/__/____]
Your Insured: [________________________________]
Policy Number: [________________________________]
Claim Number: [________________________________]
Dear [________________________________]:
This firm represents [________________________________] ("Claimant") in connection with the motor vehicle collision that occurred on [__/__/____] in [________________________________] County, Illinois. This letter constitutes a formal demand for settlement of all claims arising from this incident.
I. ILLINOIS-SPECIFIC LEGAL FRAMEWORK
A. Statute of Limitations
Section 13-202 generally requires an action for damages for injury to the person to be commenced within two years after accrual. Section 13-205 generally supplies a five-year period after accrual for an action to recover damages for injury to real or personal property. Determine accrual, tolling, defendant-specific immunities or notice rules, and any shorter controlling period before stating a deadline.
Preliminary calculated filing date: [__/__/____]. Counsel must confirm this date and file earlier when required.
B. Modified Comparative Negligence (51% Bar)
Illinois follows modified comparative negligence under 735 ILCS 5/2-1116. A plaintiff may recover damages only if the plaintiff's fault is not more than 50% of the proximate cause of the injury. If the plaintiff is more than 50% at fault, recovery is completely barred. Where recovery is permitted, damages are reduced by the plaintiff's percentage of fault.
Based on the evidence summarized below, Claimant contends that Claimant's contributory fault is [ZERO / ___] percent.
C. Joint Liability
Under 735 ILCS 5/2-1117, all defendants found liable are jointly and severally liable for the plaintiff's past and future medical and medically related expenses. For all other (non-medical) damages, a defendant whose fault is less than 25% of the total fault is severally liable only for its proportionate share, while a defendant whose fault is 25% or greater remains jointly and severally liable.
D. Seat Belt Evidence
Under 625 ILCS 5/12-603.1, failure to wear a seat belt is not admissible as evidence of negligence or contributory negligence and cannot be used to reduce damages.
E. Minimum Insurance Requirements
Section 7-601 requires covered vehicles to carry liability insurance in amounts not less than section 7-203. Section 7-203 currently states minimum limits of $25,000 for bodily injury or death of one person, $50,000 for bodily injury or death of two or more persons in one crash, and $20,000 for injury to or destruction of others' property in one crash. Confirm the actual policy limits and every additional coverage source.

XIII. INSURANCE-PRACTICES AND SECTION 155 GATE
215 ILCS 5/154.6 — Unfair Claims Settlement Practices
Section 154.5 defines when acts listed in section 154.6 constitute an improper claims practice. Section 154.6 includes, among other acts, failure to acknowledge pertinent claim communications with reasonable promptness, failure to adopt reasonable investigation and settlement standards, failure to attempt prompt and equitable settlement when liability has become reasonably clear, and failure to provide a reasonable and accurate explanation of a denial or compromise offer. Any assertion should identify the exact subsection and facts and should not imply that sections 154.5-.6 themselves state a private damages remedy.
215 ILCS 5/155 — Attorney Fees and Penalties
Section 155 applies in an action by or against an insurer in which the insurer's liability on a policy, the amount payable under it, or unreasonable delay in settling a claim is at issue. If the court finds the action or delay vexatious and unreasonable, it may allow reasonable attorney fees, other costs, and an additional amount not exceeding one of section 155(1)(a)-(c)'s three ceilings.
Capacity check: Before asserting section 155, identify why this Claimant is a proper party to a qualifying policy-based action (for example, as an insured or through another legally valid basis) and verify controlling case law. If this is only a third-party tort demand to the alleged tortfeasor's liability carrier and no qualifying basis exists, delete the section 155 demand rather than threatening an unavailable remedy.
XIV. ENCLOSED DOCUMENTS
☐ Medical records and bills from all treating providers
☐ Police/crash report
☐ Photographs of vehicle damage and injuries
☐ Employer verification of lost wages
☐ Property damage estimates/repair invoices
☐ Witness statements (if available)
☐ [________________________________]
XV. RESPONSE REQUESTED
Please confirm receipt and provide a substantive response within thirty (30) days. Failure to respond will be considered a rejection of this demand.

A demand letter is a formal written request to fix a problem or pay what is owed, sent before anyone files a lawsuit. It gives the other side a real chance to settle, creates a record of your attempt to resolve things, and in many cases (unpaid debts, insurance claims, broken contracts) starts a legally required response window. A well-written demand letter lays out what happened, what you want, and a deadline to act, which is often enough to get results without ever going to court.
