The general rule: three years
Under Wis. Stat. § 893.54(1m), most personal injury claims must be filed within three years of the date of injury.
Wrongful death: shorter, but only for motor vehicle cases
Here's a genuinely narrow carve-out worth knowing. Wrongful death claims arising specifically from an accident involving a motor vehicle get a shorter two years under § 893.54(2m) — while wrongful death from other causes continues to follow the general three-year rule.
Property damage: split by whether a contract exists
Property damage claims follow a genuinely distinctive split under § 893.52: six years if the claim arises under a written contract, but only three years if there's no contract involved.
A real trap: wrongful death from medical malpractice
A wrongful death claim stemming from medical malpractice doesn't actually follow the wrongful death rule at all. See our full guide to Wisconsin's discovery rule and tolling for this genuinely counterintuitive real court holding.
Government claims: a strict 120-day notice
Claims against a government entity follow their own separate notice framework, enforced with real strictness. See our full guide to Wisconsin government claim deadlines.
