Wisconsin Statute of Limitations for Personal Injury Claims
In Wisconsin, you have 3 years from the date of injury to file a personal injury lawsuit (Wis. Stat. § 893.54). For wrongful death caused by a car accident, the deadline is just 2 years from the date of death. Miss these deadlines and you lose your right to compensation — permanently.

Key Takeaways
- Wisconsin's statute of limitations for most personal injury claims is 3 years from the date of injury under Wis. Stat. § 893.54(1m).
- Wrongful death lawsuits must be filed within 3 years of the date of death — except when death results from a car accident, which has a 2-year deadline.
- Claims against Wisconsin government entities require a written notice of claim within 120 days of the incident under Wis. Stat. § 893.80, followed by a lawsuit within 6 months of claim denial.
- For minors (under 18), the statute of limitations is tolled until they turn 18, giving them until age 20 to file.
- Wisconsin's discovery rule may extend the filing deadline when injuries are not immediately apparent — the clock starts when you discover or reasonably should have discovered the injury.
- If you miss the statute of limitations, the court will almost certainly dismiss your case regardless of how strong your claim is.
The general rule: 3 years from the date of injury
Under Wis. Stat. § 893.54(1m), you have three years from the date of your injury to file a personal injury lawsuit in Wisconsin. This applies to car accidents, slip and falls, dog bites, workplace injuries, and most other types of personal injury claims.
The three-year clock starts on the date the injury occurs — not the date you hire a lawyer, not the date you finish medical treatment, and not the date you realize how serious your injuries are (unless the discovery rule applies). Once the deadline passes, the defendant can ask the court to dismiss your case, and the court will grant that request.
Three years may sound like plenty of time, but building a strong personal injury case requires gathering evidence, obtaining medical records, consulting experts, and negotiating with insurance companies. Attorneys who handle Wisconsin injury claims recommend starting the process within weeks of the accident, not years.
Wrongful death: 3 years, or 2 years for auto accidents
When a personal injury causes death, surviving family members can file a wrongful death lawsuit under Wis. Stat. § 895.04. The general deadline is 3 years from the date of death.
There is one critical exception: when death results from a motor vehicle accident, the wrongful death statute of limitations is shortened to 2 years from the date of death. Given that car accidents are one of the leading causes of wrongful death claims in Wisconsin, this shorter deadline catches many families off guard.
The wrongful death claim belongs to the personal representative of the deceased person's estate. If no estate has been opened, a family member must petition the court to appoint one before the lawsuit can be filed — another reason to start the process early.
Government claims: 120-day notice required
If your injury was caused by a Wisconsin government entity — a city, county, state agency, or government employee acting in their official capacity — you face a much shorter initial deadline. Under Wis. Stat. § 893.80, you must serve a written notice of claim within 120 days of the incident.
The notice must include a description of the circumstances of the claim, be signed by the injured party (or their agent or attorney), and be properly served on the government body. Failure to file this notice within 120 days can bar your claim entirely, even if the 3-year statute of limitations has not yet expired.
After filing the notice, the government entity has 120 days to allow or disallow the claim. If they disallow it (or fail to respond within 120 days, which counts as a disallowance), you then have 6 months from the date of disallowance to file a lawsuit. This means the effective maximum timeline for government claims is approximately 3 years and 120 days, but the 120-day notice is a hard deadline that must not be missed.
Exceptions for minors and individuals with legal disabilities
Under Wis. Stat. § 893.16, the statute of limitations is tolled (paused) for individuals who have a legal disability at the time of injury. In Wisconsin, legal disability includes being a minor (under age 18) or being adjudged mentally incompetent.
For minors, the 3-year statute of limitations does not begin to run until the child turns 18. This means a minor injured in an accident has until their 20th birthday to file a personal injury lawsuit. However, a parent or guardian can file on the child's behalf at any time before then, and there are practical reasons to do so — evidence deteriorates, witnesses become harder to locate, and memories fade.
For individuals who are mentally incompetent at the time of injury, the statute is similarly tolled until the disability is removed. If the person regains competence, the normal limitation period begins running at that point.
The discovery rule: when injuries aren't immediately apparent
Wisconsin recognizes the discovery rule, which can extend the statute of limitations in cases where the injury was not immediately known or discoverable. Under this rule, the 3-year clock does not start on the date of the incident but on the date the injured person discovers — or, exercising reasonable diligence, should have discovered — the injury and its cause.
The discovery rule most commonly applies in medical malpractice cases, where a surgical error or misdiagnosis may not become apparent for months or years. It can also apply in toxic exposure cases and other situations where harm develops gradually.
The discovery rule does not give you unlimited time. You must still file within 3 years of the date you knew or should have known about the injury. Courts will examine whether a reasonable person in your situation would have discovered the injury sooner, and the burden of proving that delayed discovery was reasonable falls on the injured party.
What happens if you miss the deadline
If you file a personal injury lawsuit after the statute of limitations has expired, the defendant will raise it as a defense. Wisconsin courts treat the statute of limitations as a strict bar — there is no grace period, no good-cause exception for most cases, and no judicial discretion to extend it simply because the claim has merit.
Missing the deadline means you lose the ability to file a lawsuit. Without the leverage of a potential lawsuit, insurance companies have no incentive to negotiate a fair settlement. In practice, missing the statute of limitations means losing your claim entirely.
This is why personal injury attorneys in Wisconsin strongly recommend consulting a lawyer as soon as possible after an injury. Even if you are unsure whether you have a case, a brief consultation can clarify your deadlines and protect your right to file.
Specific limitation periods for common claim types
While the 3-year general rule covers most personal injury claims, certain types of cases have their own statutes of limitations in Wisconsin. Medical malpractice claims must be filed within 3 years of the injury date, but are subject to a 5-year statute of repose from the date of the act or omission, whichever comes first. Product liability claims also follow the 3-year rule under Wis. Stat. § 893.54 but may involve different accrual dates depending on when the defect was discovered.
For property damage claims (as opposed to personal injury), Wisconsin has a 6-year statute of limitations. Workers' compensation claims follow their own separate timeline and procedures under the Wisconsin Worker's Compensation Act. If your injury involves multiple legal theories or defendants, different deadlines may apply to different parts of your case — another reason to get legal advice early.
