Wisconsin Statutes of Limitations for Civil Cases

Understanding Wisconsin's statutes of limitations is critical for any litigant or attorney. Missing a deadline can permanently bar a claim, regardless of its merits. Wisconsin uses Wis. Stat. § 893, which contains the state's primary limitations framework.

Personal Injury

Limitation Period: 3 years

Statute: Wis. Stat. § 893.54

When the Clock Starts: The statute of limitations begins running on the date the plaintiff discovers (or reasonably should have discovered) the injury. For most acute injuries—such as a slip-and-fall or motor vehicle collision—this is straightforward: the clock starts on the date of the incident.

Discovery Rule Application: Wisconsin recognizes the discovery rule, which can extend the filing deadline in cases where injury is not immediately apparent. For example, if a defective product causes gradual harm that the plaintiff doesn't notice for months, the clock may start when the plaintiff discovered or reasonably should have discovered the injury, not when the defendant's conduct occurred.

Breach of Written Contract

Limitation Period: 6 years

Statute: Wis. Stat. § 893.43

When the Clock Starts: The clock begins running on the date of the breach, not the date the contract was signed. If a party fails to pay on a due date specified in a written contract, the statute of limitations starts on that due date.

Key Distinction: Written contracts receive more favorable treatment than oral contracts under Wisconsin law. A written instrument creates certainty that presumptively protects creditors with documentation.

Breach of Oral Contract

Limitation Period: 6 years

Statute: Wis. Stat. § 893.43

When the Clock Starts: Like written contracts, the clock begins on the date of breach. However, proving breach of an oral contract is far more difficult than proving breach of a written contract, since the parties typically dispute whether an agreement was even made.

Practical Note: Oral contracts are notoriously hard to litigate. Absent corroborating witnesses, written communications, or partial performance, courts may dismiss these claims on credibility grounds even before reaching the statute of limitations question.

Fraud

Limitation Period: 3 years

Statute: Wis. Stat. § 893.54

When the Clock Starts: The clock begins on the date the plaintiff discovered (or reasonably should have discovered) the fraudulent conduct. This typically means when the plaintiff discovered or should have discovered the misrepresentation and its falsity.

Wisconsin's Approach: Wisconsin courts apply the discovery rule strictly in fraud cases. The plaintiff cannot simply assume they should have known about the fraud; the statute runs from when they either knew or acted with reasonable diligence in discovering the fraud. This can significantly extend the apparent three-year window.

Property Damage

Limitation Period: 3 years (for realty); 6 years (for personal property)

Statute: Wis. Stat. § 893.54 (realty); Wis. Stat. § 893.43 (personal property)

When the Clock Starts:

Example: If a contractor negligently damages a homeowner's foundation and the damage goes undetected for two years before discovery, the three-year clock may not start until discovery. However, courts may shorten this if the property owner should have discovered the damage through reasonable inspection.

Medical Malpractice

Limitation Period: 3 years for discovery of injury; 5-year absolute repose period

Statute: Wis. Stat. § 893.55

When the Clock Starts: The clock begins on the date the plaintiff discovers (or reasonably should have discovered) the injury caused by medical negligence.

Absolute Repose Period (Critical): Even if the discovery rule would extend the deadline, no medical malpractice action may be brought more than 5 years after the date of the alleged negligent act or omission, regardless of when the plaintiff discovered the injury. This is an absolute bar.

Example: A surgeon negligently leaves a foreign object inside a patient in 2020. The patient doesn't discover this until 2022 (within the 3-year discovery period). However, the patient cannot sue in 2026 if the negligent act occurred in 2020 because the 5-year repose period will have expired. The repose period runs from the act or omission, not from discovery.

Exceptions to the Repose Period: The repose period does not apply if the defendant fraudulently concealed the malpractice or if the plaintiff was a minor at the time of injury (special tolling applies).

Wrongful Death

Limitation Period: 3 years

Statute: Wis. Stat. § 895.03

When the Clock Starts: The clock begins on the date of death, not the date of injury. This is a critical distinction.

Standing Issue: The claim must be brought by the personal representative of the decedent's estate or by the surviving spouse or heirs. The clock does not extend based on when the survivors discovered the wrongful death; it runs from the date of death itself.

Defamation, Libel, and Slander

Limitation Period: 3 years

Statute: Wis. Stat. § 893.54

When the Clock Starts: The clock begins on the date the defamatory statement is published or communicated to a third party, not the date the plaintiff discovers the statement.

Practical Issue: For statements published in newspapers, broadcasts, or online, determining the exact publication date can be critical. Online defamation presents ongoing challenges: does republication (re-posting, re-tweeting) restart the clock? Wisconsin courts generally treat republication as a new publication that starts a new statute of limitations period.

Trespass

Limitation Period: 3 years (for personal injury trespass); 6 years (for property damage trespass)

Statute: Wis. Stat. § 893.54 (personal injury); Wis. Stat. § 893.43 (property damage)

When the Clock Starts:

Continued Trespass Rule: Wisconsin recognizes that if a defendant continues to trespass after the plaintiff demands cessation, each day of continued trespass may constitute a new actionable wrong, potentially restarting the limitations period.

Debt Collection and Promissory Notes

Limitation Period: 6 years (for open accounts and promissory notes)

Statute: Wis. Stat. § 893.43

When the Clock Starts: The clock begins on the date of the last payment or acknowledgment of the debt. For promissory notes, if no payment is made, the clock starts on the due date specified in the note.

Partial Payment Doctrine: A partial payment on a debt may restart the statute of limitations clock. However, this only occurs if the payment is made with the intent to acknowledge the debt or revive the claim. A payment made under protest or without acknowledgment may not restart the clock.

Promissory Note Specifics: A written promissory note falls under the 6-year statute, not the 3-year personal injury statute, even if the note involves an injury-related loan or settlement.

Discovery Rule and Delayed Accrual

Wisconsin's discovery rule permits the statute of limitations to begin running only when the plaintiff discovered (or reasonably should have discovered) the injury or basis for the claim, rather than when the defendant's wrongful act occurred.

Critical Limitations:

Tolling Provisions

Wisconsin law provides several tolling (pause) mechanisms that extend the statute of limitations deadline:

Minority: If the plaintiff was under 18 years old when the cause of action accrued, the statute of limitations does not begin running until the plaintiff reaches age 18. However, this does not apply to wrongful death claims. Statute: Wis. Stat. § 893.04

Mental Incapacity: If the plaintiff was under legal guardianship or adjudicated incompetent, the statute of limitations is tolled until a guardian is appointed or the incapacity ends. Statute: Wis. Stat. § 893.04

Absence from the State: If the defendant is absent from Wisconsin for an extended period, the time of absence does not count toward the statute of limitations. However, this provision is rarely invoked in modern practice. Statute: Wis. Stat. § 893.07

Military Service: Time spent on active duty in the U.S. military does not count toward the statute of limitations for the active-duty servicemember. Statute: Wis. Stat. § 893.08

Unique Wisconsin Rules and Exceptions

Notice of Claim (Government Tort Claims): Before suing Wisconsin municipalities or state agencies, plaintiffs must file a notice of claim within 120 days of injury. This is a condition precedent separate from the statute of limitations. Statute: Wis. Stat. § 893.80

Reformation and Equitable Estoppel: Courts may toll the statute of limitations in rare cases where the defendant fraudulently concealed the claim or where equitable estoppel prevents the defendant from invoking the statute. These doctrines are narrowly construed.

Relation Back of Amendments: Under Wis. Stat. § 803.06 (civil procedure), an amendment adding a party or changing the cause of action may relate back to the original complaint if the new claim arises out of the same transaction and the new defendant received sufficient notice within 90 days of the complaint.

What Happens If You Miss the Deadline

Dismissal is Mandatory: If a defendant raises the statute of limitations as an affirmative defense, the trial court must dismiss the claim upon motion. There is no discretion to extend the deadline based on fairness or prejudice.

Timing of Assertion: A defendant must raise the statute of limitations either in a motion to dismiss before answering or in the answer itself. Failure to timely assert the defense may result in waiver, though courts construe waiver narrowly.

No Equitable Tolling for Plaintiff Mistake: Wisconsin courts generally do not toll the statute of limitations simply because a plaintiff missed the deadline due to their own attorney's negligence or mistake. However, narrow exceptions exist for fraud or misconduct by the defendant.

Calculating the Deadline Accurately

Date Calculation Method: Under Wis. Stat. § 893.02, when calculating a statute of limitations deadline, the day the cause of action accrues is not counted. If the cause of action accrues on January 15, and the statute runs for 3 years, the deadline is January 15 of the third year following (January 15, three years later).

Filing vs. Service Deadline: In Wisconsin, the statute of limitations is satisfied if the complaint is filed before midnight on the deadline date. Service on the defendant can occur afterward, provided the plaintiff diligently pursues service under the Wisconsin civil procedure rules.

Leap Years: When calculating multi-year periods, leap years are counted normally. A 3-year deadline beginning on a date in a leap year will expire three years later, accounting for the extra day.
