Every personal injury case in Arizona has a hard legal deadline called a statute of limitations — a window of time within which you must file a lawsuit or permanently lose your right to seek compensation. Missing this deadline is almost always fatal to your case, regardless of how strong your underlying claim is. Understanding these deadlines before they pass is critical.

The General Rule: Two Years for Most Personal Injury Cases

Under Arizona Revised Statutes § 12-542, the statute of limitations for most personal injury claims — including car accidents, slip and falls, dog bites, and other negligence-based injuries — is two years from the date of the injury. For wrongful death claims, the two-year period runs from the date of the deceased person's death.

This is a strict deadline. Arizona courts rarely grant exceptions, and insurance companies know exactly when your window closes. Some insurers deliberately extend negotiations to allow the deadline to pass — eliminating their entire exposure without paying anything.

Specific Limitations Periods in Arizona

• General personal injury (car accidents, slips, falls, dog bites): 2 years (ARS § 12-542)
• Wrongful death: 2 years from date of death (ARS § 12-542)
• Medical malpractice: 2 years from date of injury or date of discovery (ARS § 12-564)
• Product liability: 2 years from date of injury
• Claims against Arizona state government: 1 year (ARS § 12-821), with a 180-day notice of claim requirement
• Claims against Arizona cities/counties/local governments: 180-day notice of claim required (ARS § 12-821.01), then 1 year to sue

Tolling: When the Clock Is Paused

Arizona law recognizes specific circumstances that can pause — or "toll" — the running of the limitations period:

• Minority of the plaintiff: If the injured person is under 18, the limitations period generally does not begin until they turn 18
• Legal incapacity: If the injured person lacks legal capacity at the time of the injury, the period may be tolled during the incapacity
• Fraudulent concealment: If the defendant fraudulently concealed the cause of action, the period runs from when the plaintiff discovered or should have discovered the fraud
• Defendant's absence from Arizona: Time during which the defendant is absent from the state may not count against the limitations period

The Government Claim Trap: 180 Days, Not Two Years

One of the most dangerous limitations pitfalls in Arizona involves government entities. If your accident involved a government vehicle, a city bus, a dangerous road maintained by ADOT or a county, a public school, or any other governmental actor, you must file a formal Notice of Claim with that entity within 180 days of the injury — just six months. Missing this notice requirement typically bars your claim entirely, even if you file within two years. Government entity accidents require immediate action.

Frequently Asked Questions

Does the limitations period start on the accident date or when I discovered my injuries?

Generally the accident date. For most personal injury cases, the clock begins when the injury occurs, not when you realize the full extent of your injuries. The narrow "discovery rule" exception applies primarily to cases where the injury itself was not discoverable at the time it occurred — such as certain toxic exposure or medical malpractice situations — not simply cases where the victim underestimated the severity of their injuries.

What if the at-fault driver was a minor?

You can still pursue a claim against a minor driver. Arizona law allows minors to be named as defendants in personal injury actions, and their parents may have independent liability depending on the circumstances. The limitations period for your claim as the injured adult runs from the accident date.

I have been negotiating with the insurance company for 18 months. Should I be worried about the deadline?

Yes — urgently. Insurance companies do not pause the statute of limitations. If you have been negotiating for 18 months and have not filed a lawsuit, you may have only 6 months remaining. Contact an attorney immediately. Filing a lawsuit does not mean you stop negotiating — cases settle after filing all the time. But you must preserve your legal rights by filing before the deadline.

Can I sue if the at-fault driver left the state after the accident?

Yes, and the time the defendant is absent from Arizona may not count against the limitations period under the absence tolling provision. Arizona courts can exercise jurisdiction over out-of-state defendants through Arizona's long-arm statute.

What happens if I miss the statute of limitations?

The defendant's attorney will file a motion to dismiss based on the expired limitations period. Courts almost always grant these motions. Your case will be dismissed and you will lose your right to compensation regardless of how severe your injuries were or how clearly the other party was at fault. This is why acting promptly and retaining an attorney early is so important.
