Arizona Diminished Value Claims
What Arizona Drivers Need to Know
Get in an accident in Phoenix, Tucson, or Mesa that wasn't your fault, and repairing the car doesn't erase the problem — a vehicle with an accident on record sells for less than one that's never been wrecked, even after top-quality bodywork. Arizona law recognizes that gap as part of your property damage claim, and its courts have confirmed you don't need to sell the car to prove the loss. You have two years from the accident date to file, so gathering documentation early matters. For a deeper dive into how these claims work, see our diminished value claim guide.
If your vehicle was declared a total loss instead of being repaired, see Arizona total loss appraisals. For what our report includes and what it costs, see our diminished value report service.
Every report is prepared using our Premier Market Comparison Method, built on real world market data and structured for insurance review.

Understanding Diminished Value in Arizona
What diminished value is, what drives the amount, and what a Arizona 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 Arizona
- 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 Arizona Courts Have Ruled on Diminished Value
Arizona's courts have addressed diminished value more than once, and their rulings make clear that a repair estimate doesn't tell the whole story.
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 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 between the vehicle's value immediately before and immediately after the damage — a measure that can include repair costs plus any remaining loss in value once those repairs are done. The court also held that owners aren't required to sell or transfer a damaged vehicle to establish a diminished value claim; the loss occurs at the time of damage and can be proven through expert appraisal of pre-loss and post-repair market value.

Arizona Diminished Value: Common Questions
Below are answers to common questions about Arizona diminished value claims, including how claims work, time limits, and how loss in market value is calculated after an accident.
Are diminished value claims allowed in Arizona?
Yes — Arizona permits third-party diminished value claims against the at-fault driver's insurance carrier.
What if the other driver caused the accident?
You'd file against their insurer. Arizona is a fault-based state, so the responsible driver's carrier may owe compensation for the market value loss.
Does my own insurance cover this?
Typically not, unless your policy specifically adds first-party diminished value coverage.
How is the loss actually calculated?
There's no official Arizona formula — insurers often lean on internal models, but a VIN-specific comparison of real comparable sales gives a more accurate read on resale impact.
What's the deadline to file?
Arizona generally allows two years from the accident for property damage claims. The deadline is set by A.R.S. § 12-542.
Do insurers pay out without a dispute?
Usually not without documentation — supporting evidence is typically necessary to secure fair compensation.
Do I need an appraisal for an Arizona diminished value claim?
It isn't required, but an independent, market-based report documents the loss in a format insurers can review.
