Procedural Details in Arizona

Arizona follows the pure comparative fault doctrine under Arizona Revised Statutes Section 12-2505, allowing injured plaintiffs to recover even when substantially at fault — their award is reduced proportionally. Arizona is a traditional tort (at-fault) auto insurance state; it does not have a mandatory no-fault system. Arizona law does not impose general caps on personal injury compensatory damages, although medical malpractice cases have separate caps. Claims against Arizona government entities require compliance with the notice of claim statute under ARS 12-821.01, which requires filing a notice within 180 days of the incident. This government claim deadline is significantly shorter than the two-year limitation for private parties and is strictly enforced.

Frequently Asked Questions

What is the deadline to file a personal injury lawsuit in Arizona?

Under Arizona Revised Statutes Section 12-542, you generally have two years from the date of injury. If your claim is against a government entity (city, county, or state), Arizona Revised Statutes Section 12-821.01 requires a notice of claim to be filed within 180 days of the incident. Missing the government notice deadline may permanently bar your claim even before the two-year period expires.

How does Arizona's comparative fault system work?

Arizona uses pure comparative fault under ARS 12-2505. This means even if you are mostly at fault for an accident, you may still recover a proportional share of damages. For example, if your damages are $50,000 and you are found 60% at fault, you could potentially recover $20,000. There is no threshold that bars recovery based on your percentage of fault.

Does Arizona have damage caps for accident victims?

Arizona generally does not cap compensatory damages for personal injury accident cases. Injured parties may seek recovery for medical expenses, lost income, pain and suffering, and other losses without a statutory ceiling. However, different rules apply to medical malpractice and government entity cases.

Is Arizona a no-fault auto insurance state?

No. Arizona is a fault-based auto insurance state. If you are injured in an accident caused by another driver, you typically pursue that driver's liability insurance for compensation. Arizona requires minimum liability coverage but does not mandate personal injury protection (PIP) insurance.
