Demand Letter to Insurance Company: Car Accident Sample

A demand letter is a written request to an insurance company asking for a specific dollar amount to settle your car accident claim. It states the facts, blames the at-fault party, itemizes your losses, and sets a deadline to respond. That’s the whole job. Until you send one, your claim is just a phone file an adjuster can sit on. Once you do, there’s a number on the table and a clock running. This guide walks through what goes in the letter, a section-by-section template you can copy, how to send it so delivery is provable, and what to do when the insurer says no.

What a demand letter has to contain

Skip any of these pieces and the adjuster has a reason to stall or undercut you. A complete letter does five jobs:

1. The facts. Date, time, and exact location of the crash. What you were doing, what the other driver did, what happened as a result. Plain and chronological.
2. Liability. One or two sentences naming the at-fault driver and why the wreck was their fault. Point to the police report and its report number if one exists.
3. Itemized damages. Every loss as its own line with a number: vehicle repair estimate, medical bills, prescription costs, lost wages, towing, rental car. List them, then total them.
4. The demand. One specific dollar figure you want to settle for. Not a range. A number.
5. A deadline. A firm date to respond, commonly 30 days (some use 14), with a clear statement of what you’ll do if they miss it (escalate, file a complaint, or sue).

Attach the proof for every dollar you claim: the repair estimate, photos of the damage, medical bills, a wage letter from your employer, and the police report. The letter makes the argument. The attachments make it stick.

A demand letter template you can follow

Most demand letters use the same skeleton. Copy the structure, drop in your own facts, and keep the tone flat and factual. You’re building a record, not venting.

1. Your header. Your full name, address, phone, and email. The date. The insurer’s name and claims address. The claim number and the at-fault driver’s policy number if you have it.

2. Subject line. Something like: Demand for Settlement — Claim No. [number], Date of Loss [date].

3. The facts paragraph. “On [date] at approximately [time], I was [driving north on Main St / stopped at the light at 5th and Oak]. Your insured, [name], [ran the red light / rear-ended my vehicle], causing a collision. The crash was investigated by [police department], report number [#].”

4. The liability paragraph. “Your insured was at fault. [He failed to stop / She was cited for following too closely.] Liability is clear from the police report and the damage pattern.”

5. The damages list. Lay it out as lines, each with a figure:

• Vehicle repair (estimate attached): $______
• Medical bills (bills attached): $______
• Prescriptions / out-of-pocket: $______
• Lost wages (employer letter attached): $______
• Towing and rental: $______
• Total demand: $______

6. The demand and deadline. “I demand $[total] to settle this claim in full. Please respond in writing within [30] days of this letter. If I do not hear from you by [date], I will pursue all available remedies, including a complaint to the [state] Department of Insurance and a lawsuit.”

7. Close. “I look forward to your response. Sincerely, [name].” Then list your attachments.

For a crash with injuries, you can add a short paragraph on pain and impact — how the injury changed your daily routine, what activities you couldn’t do. Keep it concrete and brief. Adjusters discount drama; they respond to documented loss.

Here is the skeleton above filled in so you can see how the pieces fit together. The names, addresses, dollar amounts, and claim numbers below are fictional examples for illustration only — replace every detail with your own.

How to send it so delivery is provable

How you mail the letter matters almost as much as what’s in it. Send it by certified mail with return receipt requested. That gives you proof the insurer received it and the date they got it — which is what starts your deadline clock and what you’ll show a judge later if it comes to that. Keep a full copy of the letter and every attachment for yourself.

A few dollars on certified mail now can save you a fight over “we never got it” down the road. If you also email a copy, request a read receipt. The point isn’t just getting the letter there. It’s being able to prove it got there.

How long the insurer has to respond

This is where people get tripped up, so be clear-eyed: there is no single nationwide deadline forcing an insurer to answer a settlement demand. What exists is a patchwork of state rules, and they mostly govern the early stages of a claim, not the demand itself.

Many states follow the National Association of Insurance Commissioners’ Unfair Claims Settlement Practices Act model, which requires insurers to acknowledge and act on claims promptly and to attempt a fair settlement when liability is reasonably clear. Some states attach numbers. California, for example, requires an insurer to acknowledge a claim within 15 days and then accept or deny it within 40 days of getting proof. New York has its own response-window rules. Your state may differ, and these timelines often apply to the claim broadly rather than to your demand letter specifically.

Check your own state’s rule before you count on a deadline. Search your state Department of Insurance website for its claim-handling or “prompt payment” regulations. In practice, most insurers answer a demand within 30 to 60 days. The deadline you put in your own letter isn’t a law — it’s a signal that you’re organized and ready to escalate, and that alone often speeds things up.

When they say no — or say nothing

A first response is rarely the final word. Insurers often counter low, or go quiet, to see if you’ll fold. Climb this ladder when that happens:

1. Counter the lowball. If they offer less than your demand, you can accept, counter, or hold. Counter in writing with your documentation again. The number is negotiable. The proof is what gives you the upper hand.
2. Go over the adjuster’s head. Ask in writing for the adjuster’s supervisor or the claims manager. The adjuster may simply lack the authority to pay what your file is worth.
3. Put “bad faith” on paper. If they ignore a documented, clearly valid claim, a written letter raising bad faith and citing your state’s unfair-claims rules often gets a fast reply. Insurers don’t want that phrase in their file.
4. File a Department of Insurance complaint. Most state insurance departments take consumer complaints online. A regulator on the thread changes the tone quickly, and patterns of complaints can trigger a market-conduct exam.
5. Take it to court. For smaller amounts, small claims court is cheap and you can handle it yourself — though claim limits and filing rules vary by state, so confirm your county’s limit first. For larger or injury claims, this is the point to bring in a car accident attorney, who can press the insurer harder and often works on contingency, meaning no fee up front.

Quick answers

Do I need a lawyer to write a demand letter? No. For a property-damage-only claim or a minor injury, many people write and send their own and settle fine. For serious injuries, disputed fault, or a stonewalling insurer, an attorney’s letter carries more weight and the contingency fee comes out of the recovery, not your pocket.

What amount should I demand? Total your actual losses — every documented bill, estimate, and lost-wage figure. For injury claims, people often ask for somewhat more than the hard costs to leave room to negotiate down to a fair number. Anchor it to documents, not a wish.

What if I don’t have all my medical bills yet? Wait until you’ve finished treatment or reached a stable point before sending. Once you settle, you can’t reopen the claim for costs that show up later.

Should I send it to my insurer or theirs? Usually the at-fault driver’s insurer, since they pay the claim. If you’re using your own coverage (uninsured motorist, or a no-fault state), send it to yours and reference the right coverage.

Bottom line

A demand letter works because it forces a fuzzy claim into a documented number with a deadline. Lay out the facts, prove every dollar, name the amount, and send it certified mail so delivery is on the record. If they lowball or stall, climb the ladder: counter, escalate, raise bad faith, file a state complaint, then court. Check your state Department of Insurance for the response and small-claims rules that apply to you. If the case is large or the injuries serious, a car accident attorney can carry the same letter a lot further.
