Auto Insurance Demand Letter Generator

Generate a professional demand letter for any car accident property damage claim in a few minutes — free, no sign-up.

Letter type Appraisal applies to claims under your own policy, when you and the insurer agree the loss is covered but disagree on the amount. Most insurance departments also take complaints through an online form; the letter text works there too.

Not legal, financial, or insurance advice. This tool gives a general, educational estimate only. Insurance laws, deadlines, and formulas vary by state, by policy, and by insurer, and they change over time. Verify anything important with your insurance policy, your state department of insurance, or a licensed attorney before relying on it. This generator produces a first draft based on what you enter. Review it carefully, attach your supporting documents, and consider legal review before sending a large or disputed claim.

What makes a demand letter effective

A strong demand letter states the facts plainly, cites a specific dollar amount backed by documentation, and sets a clear deadline. Avoid emotional language — insurers respond to evidence and a credible signal that you understand your claim’s value.

What a strong demand letter includes

The accident date, place and the other driver's name, so the claim can be matched to the right file.
One clear number, with the repair estimate, rental receipts and other bills that add up to it.
A response deadline, usually 14 to 30 days, and how to reach you.

Example: how this letter could read

On [date], your insured, [name], rear-ended my car at [place]. Your company has accepted liability under claim [number]. I am requesting $4,850: $4,120 for repairs under the attached estimate from [shop], $230 for five days of rental at $46 a day, and $500 for towing and storage. Please respond in writing within 21 days.

What to do next

Frequently asked questions

How should I send my demand letter?

Send it by email and by certified mail with return receipt requested, so you have proof of delivery and a timestamp for your deadline.

What should I attach to the letter?

Attach your repair estimate(s), photos of the damage, the police report if one exists, and any relevant receipts. The stronger your documentation, the stronger your position.

What if the insurer doesn't respond by my deadline?

Follow up in writing, consider filing a complaint with your state department of insurance, and — for larger or disputed amounts — consult a consumer or personal injury attorney about next steps, including small claims court.

How long should I give the insurer to respond?

A deadline of 14 to 30 days is common and reasonable. Check your state's claim-handling deadlines too, since the insurer may already be required to respond sooner.

Does sending a demand letter mean I am suing?

No. A demand letter is a formal written request that documents your claim and your number. It often settles the matter without court, and if it does not, it shows a judge you tried to resolve it first.
