Time matters when you’re injured due to someone else’s negligence

In Arizona, strict legal deadlines—known as statutes of limitations—determine how long you have to file a lawsuit. If you miss these deadlines, your right to compensation may be lost forever, no matter how strong your case is.

Below, we break down the statute of limitations for auto accident, personal injury, and medical malpractice claims in Arizona—plus the critical exceptions that could affect your case.

What Is a Statute of Limitations?

A statute of limitations is a state law that sets a time limit for filing a lawsuit. Once this time expires, courts will typically refuse to hear the case.

These deadlines exist to ensure fairness: evidence remains fresh, witnesses are available, and justice can be delivered efficiently.

Auto Accident Claims in Arizona

If you were injured in a car, truck, motorcycle, pedestrian, or bicycle accident, Arizona gives you:

  • Two years from the date of the accident
  • Law: Arizona Revised Statutes § 12-542

That means if another driver’s negligence caused your crash, you must file your lawsuit within two years. You can negotiate with insurance companies before then, but if the deadline passes, your legal claim is gone.

Property Damage vs. Injury Deadlines

While injury claims follow the two-year limit, property damage claims might differ. However, injury-related timelines are the most urgent and must not be delayed.

General Personal Injury Claims in Arizona

Most other personal injury lawsuits—such as slip and falls, dog bites, premises liability, or assault-related injuries—also carry a two-year deadline:

  • Two years from the date of injury
  • Applies to: All standard personal injury cases

Delaying your legal consultation may weaken your claim or disqualify you from filing altogether.

Medical Malpractice Claims in Arizona

Medical malpractice cases are more complex and operate under a special rule:

  • Two years from the date of injury or the date it was discovered (or reasonably should have been)
  • Known as the “discovery rule”

Discovery Rule Examples

  • A foreign object left in the body post-surgery
  • A delayed diagnosis of cancer
  • A medication error that surfaces months later

The clock starts when the patient knew—or should have known—that malpractice occurred.

Medical Malpractice Requirements

These cases also require:

  • Expert testimony
  • Timely investigation
  • Compliance with Arizona’s medical malpractice laws

Delay can be especially harmful in these claims due to the complexity and evidence required.

Key Exceptions to Arizona’s Statutes of Limitations

Claims Involving Minors

If the injured party is under 18, the statute of limitations is typically paused until they reach adulthood.

Government Claims

If you’re filing against a city, county, or state agency, you must file:

  • A Notice of Claim within 180 days
  • A lawsuit within one year

Failure to meet these shorter deadlines can lead to immediate dismissal of your claim.

Why Time Is of the Essence

Two years may sound like a long time, but it can pass quickly—especially while recovering from injuries or navigating insurance negotiations. Waiting can result in:

  • Lost or degraded evidence
  • Faded witness memories
  • Insurance company pushback
  • Missed legal filing requirements
