Statute of Limitations for Medical Malpractice in Wisconsin

ANO-831 deepening pass 2026-04-29: every claim_type now carries primary verbatim raw_statute_text from docs.legis.wisconsin.gov. Major correction: legal_malpractice changed from 6yr (§ 893.43 contract-default fabrication) to 3yr (§ 893.53 injury-to-character/rights, the actual WI rule per Hennekens v. Hoerl). Trespass audit: confirmed 6yr under § 893.52(1) is correct for WI; the CT/IN PI-default pattern does not apply here.

Except as provided in sub. (2), an action upon any contract, obligation, or liability, express or implied, ... shall be commenced within 6 years after the cause of action accrues or be barred. (Wisconsin does not bifurcate oral vs. written contracts; both fall under § 893.43.)

An action to recover damages for an injury to the character or rights of another, not arising on contract, shall be commenced within 3 years after the cause of action accrues, except where a different period is expressly prescribed, or be barred. (Per Hennekens v. Hoerl, 160 Wis. 2d 144, and the statute's annotations, legal malpractice actions sounding in tort are governed by § 893.53. Discovery rule applies: 3-year period begins when the injured party discovers, or reasonably should have discovered, the injury and the defendant's identity.)

An action to recover damages for libel, slander, assault, battery, invasion of privacy, false imprisonment or other intentional tort to the person shall be commenced within 3 years after the cause of action accrues or be barred.
