Diminished Value Demand Letter
A diminished value demand letter is the document that formally asks the at-fault insurer to pay what your car lost. Below is a free template you can copy, plus exactly what to include so the insurer takes it seriously.
What to include in your demand letter
Your details and the claim number
Your name, the accident date, the at-fault driver's name, and the insurer's claim number so the letter is routed correctly.
The vehicle
Year, make, model, VIN, and mileage — the exact vehicle whose value was diminished.
A clear statement of liability
State that the insured party was at fault and that you are pursuing a diminished value claim against their liability policy.
Your diminished value figure
The specific dollar amount you're demanding, supported by a certified appraisal attached as an exhibit. This is the number that carries the letter.
A response deadline
A firm, reasonable deadline (commonly 14–30 days) for the insurer to respond, and a note that you'll escalate if they don't.
Attachments
Your appraisal report, repair invoice, and accident report — the evidence that backs your number.

Frequently Asked Questions
What is a diminished value demand letter?
A diminished value demand letter is a formal written request sent to the at-fault driver's insurance company demanding payment for the resale value your vehicle lost due to the accident. It states the amount you're owed, backs it with a certified appraisal, and sets a deadline for the insurer to respond.
What should a diminished value demand letter include?
It should include your contact details and the claim number, the vehicle's year/make/model/VIN/mileage, a clear statement that the other party was at fault, your specific diminished value figure supported by a certified appraisal, a firm response deadline, and attached evidence (appraisal report, repair invoice, and accident report).
Do I need an appraisal to send a demand letter?
You can send one without an appraisal, but it will almost certainly be underpaid or ignored. The certified appraisal is what turns a demand into a documented claim the insurer must take seriously — it provides the market-based figure and the court-admissible evidence behind your number.
What happens after I send the demand letter?
The insurer typically responds within your stated deadline with a payment, a counteroffer, or a denial. If they lowball or deny, your escalation options include invoking the policy's appraisal clause or filing in small-claims court. A well-documented demand backed by an appraisal puts you in the strongest negotiating position.
