New Jersey Diminished Value Claims
What New Jersey Drivers Need to Know
A crash on the Turnpike, a fender-bender in Newark, or a parking-lot collision in Jersey City all end the same way once the repair invoice is paid: the car's accident history is now permanent, and it costs real money on resale even after a flawless repair. New Jersey law recognizes that loss in value as recoverable within a third-party property damage claim when another driver caused the accident. For a more detailed walkthrough, see our diminished value claim guide.

Understanding Diminished Value in New Jersey
What diminished value is, what drives the amount, and what a New Jersey claim needs before it goes to the insurer.
What Is Diminished Value?
Diminished value is the difference between what your vehicle was worth before the accident and what it is worth after repairs. Even quality repairs leave an accident on the vehicle history report, and buyers typically pay less for a vehicle with that history.
What Affects the Amount
- Vehicle age and mileage
- Severity of the damage
- Structural repairs
- Prior accident history
- Local market conditions
What You Need to File in New Jersey
- Completed repairs and the final repair bill
- The accident report
- Market-based documentation of the loss in value
How Insurers Review a Claim
Carriers use different approaches, from internal formulas to comparable market data. A report built on comparable vehicles with and without accident history gives the adjuster market evidence to review.
How New Jersey Courts Have Ruled on Diminished Value
New Jersey courts have addressed this issue repeatedly over the decades, consistently landing on the same conclusion: a repaired car and an undamaged one aren't worth the same thing.
Jones v. Lahn, 1 N.J. 358 (1949)
The Supreme Court of New Jersey held that, short of total destruction, the general measure of damages for injury to an automobile is the difference between the vehicle's market value immediately before and immediately after the injury.
Fanfarillo v. East End Motor Co., 172 N.J. Super. 309 (App. Div. 1980)
The Appellate Division clarified that when repairs don't restore a vehicle to its former value, the owner may recover the diminished value in addition to reasonable repair costs, provided the post-repair value is less than the pre-accident value.
Premier XXI Claims Management v. Rigstad, 381 N.J. Super. 281 (App. Div. 2005)
The court reaffirmed that a plaintiff may prove property damages either through the cost of repairs plus remaining loss in value, or by showing the straightforward difference between pre-accident and post-accident market value.
Financial Services Vehicle Trust v. Panter, 2019 N.J. Super. LEXIS 28 (App. Div. 2019)
The Appellate Division confirmed that a vehicle owner may recover for diminution in value following an accident when the claim is supported by proper evidence establishing a post-repair loss in market value.
