Diminished value in Arizona: what the law actually says

A plain-language guide for Arizona drivers whose vehicle was damaged by an at-fault driver — what's recoverable, from whom, on what clock, and what evidence carries the claim.

Is diminished value recoverable in Arizona?

Yes. Arizona follows the widely-recognized measure of damages for injury to personal property: the difference in the property's fair market value immediately before and immediately after the harm. Arizona case law (Oliver v. Henry) recognizes what every used-car buyer already knows — that a vehicle carrying an accident record sells for less than an identical clean-history vehicle, even after a proper and complete repair. That remaining gap is inherent diminished value, and it is compensable in a third-party claim.

The key word is third-party: the claim runs against the at-fault driver (and in practice, their liability insurer), not against your own policy. First-party diminished value claims under your own collision coverage are a different question and are generally excluded by policy language.

The deadline: two years

Arizona's statute of limitations for property damage actions is two years from the date of loss. In practice you should move much sooner: the claim is easiest to document while the repair file is fresh, the vehicle is still in your hands, and the adjuster who handled the property damage claim is still assigned.

Who pays

The at-fault driver's liability carrier. Diminished value rides the same legal theory as the repair bill itself — their insured damaged your property, and the measure of that damage includes the market value the vehicle cannot recover through repair. That is why our eligibility questions start with fault: without an at-fault third party, the standard claim has no payer.

What you'll need

• The at-fault carrier's name and the claim number they assigned;
• The final repair invoice — the paid one, including supplements — not the initial estimate;
• Photos of the repaired vehicle (we walk you through exactly six);
• An honest account of the vehicle's condition and history before the loss.

From there, the appraisal does the heavy lifting: licensed market data, comparable listings adjusted to your exact vehicle, a published methodology, and a signed certification an adjuster cannot dismiss as a guess.

What an appraisal is — and isn't

An independent appraisal is evidence: a credentialed, data-backed statement of what the accident record costs your vehicle at resale. It is not a demand letter, a negotiation, or a settlement. We prepare independent appraisals. We do not negotiate or settle claims — you or your attorney submit the report and negotiate the number. That separation is deliberate: an appraiser with a stake in the settlement is an appraiser an adjuster can discount.
