Arizona Car Insurance Claim Laws
How long insurers have to handle your car insurance claim in Arizona, when a car counts as a total loss, and what to do if the insurer falls behind.
Last reviewed October 24, 2026 by Ali Ahmad, MyAutoTriage editor.
Short answer
In Arizona an insurer must acknowledge your claim within 10 working days, accept or deny it within 15 working days after proof of loss, and pay within 30 days after proof of loss (interest if late). Total loss rule: the insurer decides when repairs are uneconomical; state law sets no fixed percentage. Deadline to file an injury lawsuit: 2 years.
Claim-handling deadlines in Arizona
| Acknowledge your claim | 10 working days |
|---|---|
| Accept or deny it | 15 working days after proof of loss |
| Pay after agreement | 30 days after proof of loss (interest if late) |
Rule: Ariz. Admin. Code R20-6-801(E), (G); A.R.S. § 20-462.
The decision clock usually starts once the insurer has the proof of loss it asked for, not on the day of the accident. Ask the adjuster in writing what they still need, and keep a dated log of everything you send.
When a car is totaled in Arizona
The insurer decides when repairs are uneconomical; state law sets no fixed percentage.
In practice most insurers apply the total loss formula: a car worth $15,000 with $3,000 of salvage value is usually totaled once repairs reach about $12,000. Ask the adjuster which test they used and for the valuation report.
Rule: A.R.S. § 28-2091(T)(3).
If the insurer misses a deadline or lowballs you
- Send a short written follow-up that names the deadline and asks for a decision by a specific date.
- If the offer is low, answer with evidence: repair estimates, comparable cars for sale, receipts.
- Still stuck? File a free complaint with the Arizona Department of Insurance and Financial Institutions.
If you have to sue the other driver in Arizona
Most claims settle without a lawsuit, but these rules decide how much leverage you have when you claim against the at-fault driver's insurer.
| If you were partly at fault | Pure comparative fault |
|---|---|
| Deadline to sue for injuries | 2 years |
| Deadline to sue for car damage | 2 years |
| Small claims court limit | $5,000 |
You can recover from the other driver even if you were mostly at fault, minus your share of the blame: 30% at fault means 70% of your damages.
The lawsuit deadline (statute of limitations) usually runs from the accident date, and an open insurance claim does not pause it.
Small claims court is a cheap way to recover a deductible, a rental bill or diminished value without a lawyer, as long as the amount fits under the limit.
Rules: A.R.S. § 12-2505; A.R.S. § 12-542; A.R.S. § 22-503.
Sales tax and fees on a total loss in Arizona
