Wisconsin Confidential Petition Addendum is a document used in the state of Wisconsin for certain legal proceedings. It is an addendum to a petition, and allows information to be held confidential from the public. The addendum is used to protect sensitive information related to a case, such as the names of minors or victims, financial data, or other private matters. There are two types of Wisconsin Confidential Petition Addendum: one for personal injury or death cases, and another for family law cases. The addendum is submitted along with the petition and signed by the petitioner, attorney, and judge. It is important that all information provided is valid, accurate, and complete, as any misleading or false information may result in the addendum being denied.
