How to file a diminished value claim
After an accident, your car is worth less even once it's repaired — and you can ask to be paid for that loss. Here's the whole process, step by step, plus the evidence that actually gets insurers to pay.

The 7 steps
- 1
Confirm you likely have a claim
Diminished value generally applies when someone else was at fault, the damage was more than a scratch, and your car is newer with lower mileage (it has more value to lose). A few states also let you claim against your own insurer.
- 2
Establish your pre-accident value
Look up what your car was worth the day before the crash using KBB or Edmunds. This is the anchor for the whole claim — write it down with a screenshot.
- 3
Estimate your diminished value
Run the free calculator to get a market-based figure and see it next to the insurer's 17c formula. This tells you what to ask for and how badly the formula underpays.
- 4
Build your evidence
Get an independent appraisal and pull comparable listings for your exact year/make/model — clean-history cars vs. accident-history cars. That price gap is the proof that actually moves an insurer.
- 5
Send a written demand
Write the right insurer (the at-fault driver's, or your own where allowed) with your vehicle facts, your DV figure, your evidence, and a firm response deadline. Keep everything in writing.
- 6
Rebut the lowball
Insurers often counter with a 17c number. Don't accept it on reflex — respond in writing with your appraisal and comps, and restate your demand. Persistence and documentation win these.

Escalate if they stall
If you're ignored or lowballed, file a complaint with your state's Department of Insurance, invoke your policy's appraisal clause where it applies, and consider small-claims court for the gap.
Third-party vs. first-party: who you file against
A third-party claim goes to the at-fault driver's insurer — this is the most common path. A first-party claim goes to your own insurer, which only a few states require (Georgia is the standout). Which applies to you depends entirely on your state.
Filing with your insurer
The process is the same across major insurers — State Farm, Geico, Progressive, Allstate, USAA, and the rest. Each has its own claim forms and diminished-value quirks, but the seven steps above work with any of them.
Start with your state
The rules, deadlines, and who-pays differ by state. Pick yours:
