Wisconsin Personal Injury Statute of Limitations

The Statute of limitations is the deadline for filing a personal injury lawsuit in court. In Wisconsin, 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 Wisconsin is 3 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.

Three years for personal injury. Wis. Stat. § 893.54.

Wrongful death claims must be filed within 3 years of the date of death — not the date of the negligent act that ultimately caused death. Three years for most wrongful-death actions (§ 893.54(1m)(b)); two years after the cause of action accrues if the death arose from an accident involving a motor vehicle (§ 893.54(2m)). Under the discovery rule, the claim may accrue after the date of death — when the injury is discovered or with reasonable diligence should be discovered by the wrongful death beneficiary (Christ v. Exxon Mobil Corp., 2015 WI 58).

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

3 years from injury or 1 year from discovery; 10-year repose. Noneconomic damages capped at $750K (§893.55).

Wisconsin 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.

Medical malpractice: 3 years from date of injury or 1 year from discovery (whichever is later); absolute 10-year repose.

A statute of repose sets an absolute outer deadline — it cannot be extended by the discovery rule, tolling, or any other exception. In Wisconsin, the repose period is 10 years from the date of the act or omission.

Ten-year absolute statute of repose for medical malpractice from date of act or omission (§893.55(1m)(b)).

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 Wisconsin, 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 Wisconsin government entities have separate, shorter notice requirements that must be satisfied before a lawsuit can be filed: For claims against state officers, employees, or agents, sworn written notice of the claim must be served on the Attorney General within 120 days of the event causing the injury (,). For local government claims, written notice of the circumstances of the claim must be served on the political subdivision within 120 days and an itemized claim presented to the clerk (§893.80(1d)).

Wisconsin Governmental Immunity Act. Except as otherwise provided by statute, damages recoverable by any person against political subdivisions capped at $50,000 per person ($25,000 for volunteer fire companies) (§893.80(3)). Recovery against a state officer, employee, or agent may not exceed $250,000, and no punitive damages are recoverable.
