A:In the state of Wisconsin, injury victims are allowed to file a personal injury lawsuit for up to 3 years after the date of their accident (Wisconsin Statutes section 893.54). If you wait more than 3 years after the event to try to file a claim, your lawsuit will most likely be dismissed. However, there are some exceptions to this rule for incidents involving minors (under the age of 18), and for cases where the responsible party flees the state for an extended period of time.
