What is diminished value?
Diminished value is the difference between what your vehicle was worth before an accident and what it's worth after — even with perfect repair. A car with an accident history sells for less than an identical car without one, sometimes 10–25% less depending on vehicle age, value, and accident severity.
Carfax and AutoCheck report accident history. When you sell, buyers see the report and offer less. That difference is the diminished value — and in some cases you can recover it from the at-fault driver's insurance.
When can you claim diminished value in NY?
New York allows third-party diminished value claims — meaning if another driver causes the accident, their liability insurance may owe you the diminished value in addition to repair costs. You cannot typically claim diminished value against your own collision coverage unless your policy specifically includes it (rare).
Important: the claim must be made promptly after the accident. Document the pre-accident condition (photos, maintenance records, KBB or Edmunds valuations) and post-repair condition. Get a professional diminished value appraisal — this is the key evidence.
How much can you recover?
Typical diminished value awards in NY: 10–25% of the vehicle's pre-accident value, depending on severity. A $40,000 luxury sedan with major structural repair could see $4,000–$10,000 in diminished value. A $15,000 commuter car with minor cosmetic repair might see $1,500–$3,000.
Vehicles under 5 years old and worth more than $20,000 typically have stronger diminished value claims. Older or lower-value vehicles see proportionally less recovery.
Steps to file a diminished value claim
Get the at-fault driver's insurance information from the police report. File the diminished value claim with their carrier (not yours). Hire a licensed diminished value appraiser to produce a written assessment.
Submit the appraisal with your claim. The at-fault carrier may negotiate the amount. If they refuse a fair offer, you can pursue small claims court (for amounts under $10,000) or full civil court for larger claims.
Frequently asked questions
Can I claim diminished value from my own insurance?
Usually no — collision coverage typically excludes diminished value. Some specialty policies include it; check your policy.
How much does a diminished value appraisal cost?
Typically $200–$500. The cost is recoverable from the at-fault carrier if your claim succeeds.
How long do I have to file a diminished value claim?
New York's statute of limitations for property damage is 3 years from the accident date. File earlier if possible — evidence is fresher.
