An auto accident demand letter is a formal written request to an insurer for payment of bodily-injury and property-damage losses after a crash. It summarizes how the collision happened, why their insured is legally responsible, the injuries you sustained, the medical treatment received, and every category of financial loss tied to the crash. It closes with a specific dollar demand and a reasonable deadline for the insurer to respond. The letter also identifies the claim number, confirms policy limits, and encloses evidence such as medical records, bills, wage verification, photographs, and the police report so an adjuster can evaluate liability and damages in one place.
Quick Facts
- A demand letter is usually sent once treatment stabilizes or a doctor provides a prognosis, so your losses are documented and not speculative.
- Adjusters evaluate three things in this order: liability, causation, and damages.
- Settlement communications often include Federal Rule of Evidence 408 language to signal compromise discussions.
- Recovery cannot exceed the policy’s bodily-injury limits unless other sources of payment exist.
- The statute of limitations for injury claims varies by state, so timing matters.
How to Write an Auto Accident Demand Letter
A strong demand letter reads like a concise case file. Lead with claim identifiers and liability facts, then move into injuries and treatment, followed by a precise accounting of losses. Write in plain language, avoid exaggeration, and connect each loss to the crash. Wherever possible, reference the enclosed proof by name so the adjuster can match each statement to a document.
Header with Your Contact Information
Place your name, mailing address, city and state with ZIP code, phone, and email at the top. If you were represented at treatment under your legal name and a different mailing name, use the same legal name to avoid record mismatches.
Example
John Stamos
860 Washington St, New York, NY 10998
(212) 555-0190 | [email protected]
Date
Use the mailing date. It sets the response deadline and shows that you sent the demand within the statute of limitations period.
Example
June 17, 2094
Subject Line
State the purpose clearly and include the claim number if assigned. Insurers often route mail based on this line.
Example
Subject: Auto accident settlement demand for Claim 19-87452
“Re” Line with Claim Identifiers
List the insured’s name, your name as claimant, the date of loss, and the city or location. This mirrors how insurers index claims.
Example
Re: Insured: Gary Hershberger; Claimant: John Stamos; Date of loss: January 5, 2094; Location: New York City
Opening Paragraph Describing the Crash
State the collision date, exact location, basic mechanism of impact, and the insured’s fault. Keep it factual, avoid adjectives, and reference the evidence you will enclose.
Example
I write regarding the collision on January 5, 2094, at the intersection of 8th Avenue and West 14th Street in New York City. Your insured, Gary Hershberger, struck my vehicle from behind while I was stopped at a red light. The impact caused injuries and financial losses set out below.
Liability and Fault Analysis
Explain why liability is clear or why comparative fault does not apply. Cite objective evidence such as the police report number, witness statements, traffic-camera images, or photographs. If you were stationary, say so. If there is any suggestion of shared fault, address it briefly with facts.
Example
Liability is clear. The NYPD MV-104A and scene photographs confirm a rear-end impact to my vehicle while I was stationary at a steady red signal. There is no evidence of comparative fault.
Injuries and Early Care
List each diagnosed injury using the terms in your records. Identify the first evaluation date and provider, then summarize the care sequence. Do not copy chart notes; present a readable overview tied to your records.
Example
My injuries included cervical strain, right-shoulder sprain, and post-concussive symptoms. I was evaluated the same day at Westside Urgent Care, followed by treatment with Dr. Lori Loughlin and physical therapy with Andrea Barber from January 8, 2094, through March 10, 2094.
Diagnostic Findings and Prognosis
Note imaging results, objective tests, and any provider opinions about expected recovery, flare-ups, or restrictions. If you reached maximum medical improvement, say so.
Example
Cervical spine imaging on January 12, 2094, showed soft-tissue injury without fracture. My providers anticipate intermittent neck pain with prolonged sitting and lifting and recommended a brief home exercise plan.
Pain, Daily-Life Impact, and Activities Missed
Describe the human impact without overstatement. Connect it to specific tasks, sleep, family duties, and hobbies that changed during recovery. Use time frames and concrete examples.
Example
During the first six weeks I had sleep disruption and could not complete normal childcare pickups or resume weekend basketball. Headaches were frequent in the first month and have since decreased.
Itemized Medical Bills and Records
Itemize total medical charges and out-of-pocket payments. If health insurance paid part of your care, you can still list the full billed amounts and include any lien or subrogation notice where applicable. Reference the attached itemization.
Example
Documented medical charges total $14,850 as shown in the enclosed ledger and records. Co-pays and uncovered expenses are included in the out-of-pocket category below.
Lost Wages and Employer Verification
Explain time away from work, hourly rate or salary, and how you calculated the figure. Attach a wage verification letter or pay stubs. Mention vacation or sick time used, since those are compensable losses in many claims.
Example
Lost wages are $3,600 for two weeks away from work at $1,800 per week, verified by my employer letter dated February 1, 2094.
Out-of-Pocket Costs and Property Damage
List reasonable crash-related expenses such as medications, transportation to treatment, and parking. For property damage, include the repair estimate or paid invoice and photographs.
Example
Out-of-pocket expenses are $420 for prescriptions and transportation to therapy. Vehicle repairs totaled $4,200, supported by the enclosed estimate and photographs.
The Demand and Policy-Limits Request
State a precise settlement amount and request written confirmation of the bodily-injury policy limits. The number should reflect medical evidence, pain and suffering, and any future care documented by your provider.
Example
To resolve my bodily-injury claim against Gary Hershberger, I demand $65,000. Please confirm the bodily-injury limits for the policy and respond in writing within 30 days.
Response Deadline and Method of Contact
Set a date that gives the adjuster time to review the file while keeping the claim moving. Thirty days is common. Provide the preferred mailing or email for written responses.
Example
Please respond by July 17, 2094, to the address above or by email to [email protected].
Enclosures List
Name what you are sending so the adjuster can match each record. Common items include medical records and bills, employer wage letter, photographs, police report, and repair estimate. If a document is pending, state that you will supplement the file.
Example
Enclosures: medical records and bills; wage verification letter; photographs; police report; repair estimate.
Settlement-Privilege Language
Close with a short sentence identifying the letter as a settlement communication. This is standard in pre-suit negotiations.
Example
This is a settlement communication under Federal Rule of Evidence 408 and comparable state rules. All rights are reserved.
Signature Block
Sign above your typed name. If you are represented by counsel, your attorney will sign and place their contact information in the header.
Example
Sincerely,
John Stamos

Evidence and Enclosures to Consider
Include the records and bills for every visit, not just summaries. Add diagnostic films and radiology reports if available. Employer letters should state dates missed, pay rate, and totals. Photographs should show both vehicles, the point of impact, and any visible injuries. If a lien holder such as health insurance or a medical provider claims repayment from settlement funds, include the lien notice so the adjuster can account for it during evaluation.
Timing and Statute of Limitations
Send the demand after you complete treatment or receive a stable prognosis so your damages are measurable. Do not wait so long that the statute of limitations becomes a risk. If the deadline is approaching and negotiations are active, you may need to protect your claim through suit filing while discussions continue.
Comparative Fault and Claim Valuation
If the insurer suggests you share fault, address each point with objective facts such as traffic controls, speed estimates, skid marks, or event-data-recorder downloads when available. Settlement figures often reflect the strength of liability evidence, the consistency of medical records, and the credibility of wage documentation. Clear documentation usually leads to faster and more accurate evaluations.
Uninsured and Underinsured Motorist Claims
If the at-fault driver lacks adequate coverage, you may pursue benefits under your own UM or UIM policy where available. The letter format is similar, but you will direct it to your carrier and cite your personal policy number. Be mindful of notice and consent-to-settle requirements in your policy language.
Use a specific number. Adjusters need a concrete figure to evaluate reserves and authority. Your number should reflect itemized medical charges, documented wage loss, property damage, and fair value for pain and suffering based on your records and prognosis. Ranges can slow reviews because they require a follow-up request for a firm demand.
Send it once treatment is complete or a provider has issued a prognosis that explains future flare-ups or care. This timing avoids undervaluing the claim with missing bills and also prevents speculation about future medical needs. If a single follow-up visit remains, you can disclose that and plan to supplement the file.
Address it directly in the liability section. Explain the facts and cite records that reduce or eliminate comparative fault, such as a stationary position at impact or a police diagram that places the other driver outside their lane. Even with some fault, you may recover a reduced amount in many states. The letter should present a clean, factual analysis rather than arguments.
Provide the report, treatment notes, imaging results, and bills that support each statement in your letter. Adjusters rarely pay on summaries alone. If certain records are pending, state that you will supplement them. A complete file shortens evaluation time and reduces back-and-forth requests.
Yes. Many claimants begin negotiations by mail. Use accurate facts, organized evidence, and a reasonable demand grounded in the records. If liability is disputed, injuries are significant, or the policy limits appear low relative to your losses, speak with counsel about strategy before you accept payment.
