New Jersey diminished value claims: what the law says
In New Jersey you can claim diminished value from the at-fault driver, including the "stigma" of an accident history, if you can prove it. Your own policy generally won't pay it. You have six years to sue.

The short answer
Claim from the at-fault driver's insurer
Yes. You can claim the lost value from the at-fault driver's insurer.
Claim from your own insurer
No. Your own policy doesn't pay diminished value when the car is properly repaired.
Deadline to sue
6 years from the crash to sue for damage to your car
If you were partly at fault
Your claim is cut by your share of the blame, and you get nothing if you were more than half at fault.
State insurance department guidance
We found no diminished value guidance on the state insurance regulator's site.
Claiming from the other driver's insurer
In 2019 a published Appellate Division decision held that the lost value from an accident history, the "scarlet letter" a vehicle-history report shows buyers, is recoverable with sufficient proof. Repair cost plus lost value can't exceed the drop in market value or the car's value before the crash.
“we hold that the damage caused by such a "scarlet letter" is just another factor that bears on value and is recoverable if supported by sufficient proof.” — Financial Services Vehicle Trust v. Panter, No. A-2142-17T3 (N.J. Super. Ct. App. Div., approved for publication Feb. 28, 2019)
Claiming from your own insurer
In Kieffer v. High Point (2011), the Appellate Division upheld auto policies that limit the insurer to repairs and expressly exclude diminished value. A policy without that language could be read differently.
“the insurer's liability is capped at the cost of returning the damaged vehicle to substantially the same physical, operating, and mechanical condition as existed immediately before the loss.” — Kieffer v. High Point Insurance Co., 422 N.J. Super. 38 (App. Div. 2011)
The deadline
You have six years to sue over tortious injury to personal property.
“Every action at law ... for any tortious injury to real or personal property ... shall be commenced within six years next after the cause of any such action shall have accrued.” — N.J.S.A. 2A:14-1(a)
If you were partly at fault
Modified comparative fault (51% bar). You recover, cut by your share, only if your fault isn't greater than the other side's. At 50% you still recover; above that you don't.
“Contributory negligence shall not bar recovery ... if such negligence was not greater than the negligence of the person against whom recovery is sought” — N.J.S.A. 2A:15-5.1 (Comparative Negligence Act)
What this means when you're deciding
Not your fault? Ask the at-fault driver's insurer in writing. New Jersey courts accept the accident-history stigma, but you need competent proof: an appraisal or solid comparable sales.
Your own insurer generally won't pay; most policies exclude it.
Partly at fault? Up to 50%, the claim is cut by your share; above 50%, nothing.
Deadline: six years to sue. Run your numbers through the diminished value calculator first. If the typical appraisal midpoint is under $500, it is rarely worth chasing.
Is a claim worth it on your car?
The calculator runs the insurer's formula on your car, shows what appraisals usually find, and tells you whether to skip it, ask yourself, or pay for an appraisal.
Insurance department guidance: none found. Searched the DOBI auto consumer page, the 2026 Auto Insurance Buyer's Guide and related guides, the Ombudsman auto FAQ, the 'filing an auto damage claim' pages, and N.J.A.C. 11:3-10.
