Wisconsin Proof of Claim is a form used to initiate a claim process in Wisconsin, and to provide proof of a debt or claim against an individual or entity. It is most commonly used in bankruptcy proceedings. The form requires the creditor to provide information such as the name of the debtor, the amount of the debt, the type of debt, and the reasons for the debt. There are two types of Wisconsin Proof of Claim forms: an individual form and a joint form for joint debtors. The form must be signed and dated by the creditor and filed with the Clerk of the Circuit Court in the county where the debtor resides. Once filed, the Proof of Claim is used to ensure the creditor's rights are protected in the bankruptcy proceedings.
