Diminished Value Demand Letter: Template & Evidence

A diminished-value demand letter organizes your request for the market value remaining lost after repairs. It identifies the claim, explains the amount requested, and makes the supporting evidence easy to review. The letter itself does not prove eligibility or compel payment.

Confirm the claim route before using the template

The template below is for a third-party claim handled by the other driver's liability insurer. Use the claim eligibility guide first if responsibility or the applicable coverage is unclear. For your own insurer, identify your policy and the coverage under which you are requesting payment; do not use a statement that its insured caused the crash.

Check the deadline to sue and any required notice separately. Your requested response date is a practical follow-up date, not a substitute for those deadlines. An ordinary letter is also different from a statutory demand intended to preserve special legal remedies.

The parts of a documented request

1. Identification. Your name and contact details, claim number, date of loss, driver, and the vehicle's year, make, model, and VIN.
2. The basis of the claim. Briefly state what happened and whether responsibility has been accepted. Do not describe disputed fault as settled.
3. The amount and its basis. Explain the pre-accident and post-repair values, the records supporting them, and the difference requested. If this is not established yet, ask for the missing valuation information.
4. The attachments. List the repair records, photographs, available history and market information, and an appraisal if you obtained one. Attach only documents you actually have.
5. The question to resolve. Identify an incorrect input, unsupported adjustment, missing analysis, or reason for denial.
6. A requested response date. Ask for payment or a written explanation by a specific date. Choose the date with your actual filing deadline in mind.

Replace the brackets with supported facts. Delete the alternatives and attachment entries that do not apply. Do not copy a 17c calculator result as proof of market loss.

[Date] [Insurer Name] — Claims Department RE: Diminished Value Request Claim Number: [number] Date of Loss: [date] Claimant: [name and contact information] Vehicle: [year make model], VIN [VIN] To the Claims Adjuster: I am requesting review of diminished value following the [date] collision involving your insured, [driver]. [Briefly state the basis of liability and whether accepted or still disputed.] My vehicle has been repaired. [Use when an amount is supported:] I request $[amount] for the remaining loss of market value. My supporting analysis shows a pre-accident value of $[value] and a post-repair value of $[value]. The difference is $[amount]. [Explain the supporting records or appraisal and how differences in condition, mileage, and prior damage were addressed.] [Use instead when valuation information is missing:] Please provide your written diminished-value assessment, the records and market data considered, and any calculation with its inputs. If you deny the request, please identify the reason and any policy provision relied on. [If responding to an offer:] Your [date] offer used [specific input or reasoning]. I dispute that point because [reason], supported by [attachment and relevant detail]. Please review it. Attached: [list only the documents enclosed, such as final repair invoice, photographs, vehicle details, relevant market evidence, and any appraisal obtained]. Please respond by [date] with the requested valuation information or, if an amount is stated, payment or a written explanation of your position. Please identify any further information you need. Sincerely, [name] [contact information]

How to send it: 6 steps

1. Organize the available evidence. Use existing repair documents first. If a market analysis is missing, decide whether the proposed appraisal work would supply it before purchasing a report.
2. Use supported specifics. Confirm the claim number, VIN, dates, and liability statement. Check that every attachment named is included.
3. State one amount when you can support it. Explain how you reached it. If you cannot yet do that, use the information-request alternative.
4. Set a follow-up date. You might request a response within 30 days if that fits your situation, but this is not a universal legal response period. Do not let it run past a filing or notice deadline.
5. Use the insurer's confirmed delivery channel. A claims portal or adjuster's email may work; save the acknowledgment. If using postal mail, certified mail with return receipt can provide delivery evidence. Confirm the address and retain copies.
6. Keep a complete record. Save the sent version, attachments, delivery confirmation, and each response. A delivery receipt records delivery; it does not prove the claim or automatically start every legal clock.

When the insurer disagrees or does not respond

Follow up with the date and method of delivery and ask what remains unresolved. If an offer arrives, compare the written explanation with your evidence using the negotiation guide. A missed date you selected does not by itself establish bad faith.

For a handling complaint, find your state insurance department's complaint process and supply the correspondence. For a damages dispute, assess the local court rules, proper defendant, filing deadline, and cost. Do not assume that the liability insurer is the correct party to sue.

State-specific demands and first-party claims

Legal requirements for special demands depend on the state and claim type. Georgia first-party and third-party remedies have different conditions; a generic 30-day or 60-day letter does not automatically establish them. If you intend to preserve a statutory bad-faith remedy or make a time-limited settlement offer, get advice about the exact requirements before using this ordinary template.

Quick answers

Do I need an appraisal to send the letter?
No. Submit the evidence you have or request the missing valuation. Obtain a paid report only when it adds needed evidence.

Does giving 30 days force payment?
No. It states your requested response window. Applicable insurer response rules and statutory demand requirements are separate.

Must I use certified mail?
Use a confirmed method and preserve delivery evidence. Certified mail can help for postal delivery; a special legal demand may have its own delivery rules.

Can I write it myself?
You can organize a routine written request yourself. Get advice when coverage or fault is disputed, a deadline is close, injuries or a release are involved, or you need a demand with a particular legal effect.

What should I do next?
Choose the supported-amount or missing-information version, attach the relevant records, and save what you send. The next response should tell you which issue needs evidence or a correction.
