Wisconsin Portion of Judgment Regarding Surname is a legal document issued by a court in Wisconsin that legally changes a person's last name. This document is filed with the court and becomes a part of the person's official records. There are two types of Wisconsin Portion of Judgment Regarding Surname: a regular petition for change of name and a joint petition for change of name. The regular petition is used when the petitioner wishes to change their own name, while the joint petition is used when two or more people wish to change their surnames jointly. In both cases, the petitioner must provide evidence to the court that the proposed name change is in the best interests of the petitioner or petitioners. The court will review the evidence and, if satisfied, will issue a judgment granting the name change. The Wisconsin Portion of Judgment Regarding Surname is then filed with the court and becomes part of the petitioner's official records.
