Arizona Diminished Value Claims

How Diminished Value Claims Work

In Arizona, a vehicle involved in a not at fault accident may lose market value even after repairs are completed. When another driver is responsible for the accident, Arizona law allows you to pursue compensation for that loss in value from the at fault driver’s insurance company as part of your property damage claim. An Arizona diminished value claim allows you to recover the difference between what your vehicle was worth before the accident and what it is worth after repairs. Arizona is considered a diminished value state, meaning this right is recognized under state law.

Arizona Diminished Value Law

Arizona law recognizes that a vehicle may suffer a loss in market value after a collision even when repairs are properly completed. When another driver is at fault, that loss may be recovered as part of a third party property damage claim.

Farmers Insurance Co. of Arizona v. R.B.L. Investment Co., 138 Ariz. 562, 675 P.2d 1381 (Ariz. Ct. App. 1983)

The Arizona Court of Appeals acknowledged that compensation for a negligently damaged motor vehicle may include both the cost of repair and any proven residual reduction in fair market value.

Oliver v. Henry, No. 1 CA CV 10 0701 (Ariz. Ct. App. 2011)

The court reaffirmed that when personal property is damaged but not destroyed, damages are measured by the difference in the vehicle’s value immediately before the damage and its value after the damage. When a vehicle is repaired, this measure may include repair costs as well as any remaining loss in value after repairs are completed.


The court further held that Arizona law does not require a vehicle owner to sell or transfer a damaged vehicle in order to establish a diminished value claim. A loss in value occurs at the time of damage and may be proven through competent evidence, including expert appraisal of the vehicle’s pre loss and post repair market value.
