Washington Guardianship Inventory RCW 11.92_040(1) (IN) is a form that individuals and/or groups may complete to designate a guardian for the person who is incapable of making decisions for themselves. The form must be filed with the court in order to establish a guardianship. There are two types of Washington Guardianship Inventory RCW 11.92_040(1) (IN): the Petition for Guardianship and the Inventory of Assets. The Petition for Guardianship includes information about the guardian, the ward, and the type of guardianship sought. The Inventory of Assets includes a list of the ward’s property, assets, debts, and any other financial information. Once the form is completed and filed with the court, the guardian will be able to make decisions on behalf of the ward.
