When the Clock Starts
In Wisconsin, the limitations period for defamation and libel claims generally begins on When plaintiff knows or reasonably should have discovered the identity of the tortfeasor. Wisconsin recognizes a discovery rule for this claim type: Wisconsin courts have held that the cause of action under § 893.57 does not accrue until the plaintiff knows—or reasonably should know—who the tortfeasor is; particularly relevant for anonymous online publications

Exceptions That Can Extend the Deadline
- Minors: the clock is generally paused while the injured person is under 18.
- Fraudulent concealment: if the defendant actively hid the wrongdoing, the deadline may be extended until it was or should have been uncovered.
- Defendant leaves the state: absence can pause the clock in many circumstances.
- Government-claim trap: Wis. Stat. § 893.80 requires written notice of claim to the governmental body within 120 days of the event causing injury before suit may be filed against governmental entities
Wis. Stat. § 893.57 explicitly lists 'libel, slander, assault, battery, invasion of privacy, false imprisonment or other intentional tort to the person' in the 3-year category. Wisconsin is one of the few states with an express 3-year defamation period. The statute was last amended by 2009 Act 120. The discovery rule (identity of tortfeasor) comes from case law interpreting § 893.57.

What to Do Before the Deadline Runs
- Pin down your accrual date — the day the clock started — and calendar the deadline conservatively.
- Preserve evidence now: photos, records, witness contacts, bills. Evidence decays faster than deadlines.
- Send preservation/notice letters where required (especially for Wisconsin government defendants).
- If the deadline is inside 6 months, treat it as urgent — filing suit is the only reliable way to stop the clock.
