Arizona Personal Injury Statute of Limitations

The Statute of limitations is the deadline for filing a personal injury lawsuit in court. In Arizona, missing this deadline almost always means the claim is permanently barred — no matter how strong the evidence, how severe the injury, or how clear the defendant's fault.

The general personal injury statute of limitations in Arizona is 2 years from the date of injury. This covers negligence claims arising from car accidents, slip and falls, defective products, and other incidents causing bodily harm.

Wrongful death claims must be filed within 2 years of the date of death — not the date of the negligent act that ultimately caused death. Two years from date of death.

Medical malpractice claims in Arizona have specific deadline rules that may differ from the general personal injury statute.

2 years from date of injury/discovery. No medical malpractice damage caps (prohibited by AZ Constitution).

Arizona recognizes a discovery rule — the statute of limitations may start when the injury was discovered (or should have been discovered through reasonable diligence) rather than when the negligent act occurred.

This is particularly important in cases where injuries are not immediately apparent: medical malpractice (a foreign object left during surgery), toxic exposure, or defective products that cause progressive harm.

Discovery rule applied by case law. SOL begins when injury is discovered or should have been discovered.

Certain circumstances may pause (toll) the statute of limitations, effectively extending the filing deadline:

• Minority — if the injured person is under 18, the statute of limitations is typically tolled until they reach the age of majority. A parent or guardian can file on the minor's behalf before then.
• Mental incapacity — if the injured person is mentally incapacitated at the time of injury, the clock may not start until capacity is restored
• Defendant absence from the state — if the defendant leaves Arizona, the time away may not count toward the limitations period
• Fraudulent concealment — if the defendant actively concealed the injury or the cause of harm, the clock may be tolled until discovery

Claims against Arizona government entities have separate, shorter notice requirements that must be satisfied before a lawsuit can be filed: 180-day notice of claim to specific government agency (§12-821.01). 1-year SOL for lawsuits against government entities (§12-821).

Notice must contain specific facts and amount claimed. Failure to file notice bars the claim.
