Diminished Value Appraisal — File Your Claim. Get What You're Owed.
After a not-at-fault accident, your vehicle is permanently worth less — even after perfect repairs. A professional diminished value appraisal from licensed adjusters documents the real market loss and gives you the evidence to demand it back from the at-fault insurer.
⏳ Most states allow 2–3 years to file. Claims documented early settle significantly better.
17c Formula vs. Market-Based Appraisal — The Real Numbers
The insurer's 17c formula is designed to produce the smallest defensible number. Here's what it looks like on a real vehicle versus a market-based appraisal.

Professional appraisal documents the full figure with real comparables
After a not-at-fault accident, your vehicle is permanently worth less on the open market — even after professional repairs. That gap is called diminished value, and in most states you have the legal right to recover it from the at-fault driver's insurance company.
Insurance companies use the 17c formula to systematically undervalue your loss. MyFairClaim produces professional diminished value appraisal reports backed by real comparable vehicle sales — serving vehicle owners in all 50 states.

Claim Filing Guide
"They fixed the car. Not the history."
A step-by-step walkthrough that turns your appraisal into a filed, documented claim. Preview below; the full interactive guide unlocks at checkout.
1Understand Your Rights
✓ In most states you can recover diminished value from the at-fault insurer. The guide explains how your state treats third-party DV claims and what a typical filing window looks like.
2Assemble Your Evidence
Document checklist
• Your Fair Market Impact and Fair Market Value reports • Final repair invoice and estimate • Photos of damage and completed repairs • Claim number and police/incident report • Policy declarations page
3Anchor Your Number
Lead with the MFC Enhanced figure from your appraisal, not the insurer’s 17c estimate. The guide shows how to present your number so the adjuster engages with your documentation instead of their formula.
4Send the Demand Letter
Sample language
“Enclosed is an independent appraisal establishing a diminished value of $4,750 following the repair of my 2022 Honda Accord. I am requesting payment of this amount under my third-party property-damage claim…”
You’ll walk away with an editable demand letter with your appraisal attached — ready to send today.
5Set the Clock & Follow Up
⚑ If the adjuster goes quiet or offers a fraction of your number, that’s a negotiating tactic, not a final answer. The guide gives you the exact follow-up cadence and the next escalation step.

Insurance Response Guide
"They have tactics. You have truth."
Adjusters have a playbook. So do you. The guide gives you the exact response for each move they make — written by licensed adjusters.
When they push back
Low offer
Counter with the exact response language that works, anchored to your appraisal’s comparable evidence. Includes the counter-offer script.
Denial
Know exactly what to say, what to request in writing, and what to file next when they deny the claim outright.
Stalling
The follow-up cadence and escalation steps for when they simply stop responding.
Counter-offer script
“Your offer of $1,196 reflects the 17c formula, not market reality. My appraisal documents $4,750 in diminished value from 15 comparable sales. Please review the enclosed evidence and revise your offer…”
Tactics to watch for
⚑ “We don’t pay diminished value in this state” — often untrue ⚑ Citing only the 17c formula as if it were law ⚑ Verbal-only offers with nothing in writing

When negotiation stalls, you escalate on a documented path — each step raising the cost of denying a legitimate claim.

2State DOI Complaint
How and where to file a Department of Insurance complaint — which puts a regulator on notice and frequently moves a stalled claim.

Step-by-Step Process
How to File a Diminished Value Claim
Most people don't file because they don't know where to start. Here's the complete process — from confirming eligibility to collecting your settlement.
01
Confirm you have a valid claim
You need three things: (1) the accident was not your fault, (2) your vehicle was repaired — not totaled, and (3) you're within your state's statute of limitations, typically 2–3 years from the accident date. Most states allow third-party diminished value claims against the at-fault driver's liability insurance.
Filing a DV claim is against the at-fault driver's insurer — not your own policy. Your rates and deductible are unaffected.
02
Get a professional appraisal
Insurance companies have appraisers on staff. You need one too. A professional diminished value appraisal documents the difference between your vehicle's pre-accident market value and its post-repair market value using real comparable sales — not the insurer's 17c formula. This appraisal is your primary evidence.
MyFairClaim appraisals are prepared by licensed insurance adjusters and appraisers, backed by live MarketCheck comparable vehicle data.
03
Send a demand letter to the at-fault insurer
Write to the adjuster handling your claim and formally demand compensation for diminished value. Your letter should reference your appraisal, state the documented amount, and cite the at-fault driver's liability. Keep it professional and factual — you're presenting evidence, not arguing.
The Professional and Premium tiers include a demand letter generated step by step with your specific vehicle details and claim number.
04
Negotiate from your documented number
The insurer will typically respond with a counter-offer lower than your documented amount. This is standard. Respond in writing, referencing your comparable evidence. Most claims settle within 2–4 weeks of the initial demand. Having professional documentation shifts the negotiation significantly in your favor.
The Insurance Response Guide (Premium) gives you the exact response language for every common insurer pushback — low offer, denial, stalling.
05
Escalate if needed
If the insurer refuses to negotiate in good faith, you have options: invoke the appraisal clause in your policy, file a complaint with your state Department of Insurance, or pursue small claims court for amounts typically under $10,000. These are real escalation paths — not empty threats — and insurers know it.
The Insurance Dispute Guide (Premium) covers each escalation path with specific steps, timelines, and filing instructions by state.

Diminished value is the permanent reduction in your vehicle's resale market value after it has been in an accident and repaired. Even after a perfect repair, a vehicle with an accident history sells for less than an identical clean-history vehicle. That difference is called diminished value — and in most states you have the legal right to recover it from the at-fault driver's insurance company.
In most states, yes — as long as the accident was not your fault, your vehicle was repaired rather than totaled, and you are within the statute of limitations (typically 2–3 years from the accident date). A small number of states have restrictions on first-party claims. MyFairClaim serves vehicle owners in all 50 states.
The 17c formula is the method insurance companies use to calculate diminished value. It caps your claim at 10% of your vehicle's pre-accident value, then applies arbitrary multipliers for damage severity and mileage. On a $30,000 vehicle it typically produces around $1,196. A market-comparable appraisal on the same vehicle produces $4,750. The formula is not required by law — it is the lowest defensible number the insurer can offer. A professional appraisal replaces it with real comparable sales evidence.
Fair Market Value establishes your vehicle's pre-accident market value using real comparable sold vehicles — the baseline every other calculation depends on. Fair Market Impact documents the specific dollar amount your vehicle lost in value after the accident, directly refuting the insurer's 17c formula. Both reports are included in every MyFairClaim tier and together form the complete claim documentation package.
In most cases, no. A professional appraisal report is the key document. Most claims are resolved directly with the insurer using the appraisal and a demand letter. Attorneys are typically only needed if the insurer refuses to negotiate after receiving professional documentation, or if the claim proceeds to litigation.
Most states allow 2–3 years from the date of the accident. Once that window closes, your right to recover is permanently gone. Claims filed soon after repairs are completed consistently settle better than those filed years later — the documentation is fresher and the insurer has fewer grounds to dispute the loss.
No. You are filing a third-party claim against the at-fault driver's liability insurance — not your own policy. Your premiums, deductible, and claims history are completely unaffected by filing a diminished value claim.
The Insurer Has Already Run the Numbers. So Should You.
Every claim that isn't professionally documented is a claim that gets settled on the insurer's terms. Get your appraisal and put the real number on the table.
