Washington Notice of Guardianship Petition is a legal document filed in the court by an individual seeking to become the legal guardian of a minor or incapacitated adult. This document is used to initiate the guardianship process and informs the court of the petitioner's request to become guardian of the ward. The Washington Notice of Guardianship Petition is required to be served on the proposed ward, as well as other interested parties, including the ward's parents, spouse, and any other relatives who are 18 years of age or older. There are two types of Washington Notice of Guardianship Petition: the Notice of Guardianship of Minor Children and the Notice of Guardianship of Incapacitated Adults. The Notice of Guardianship of Minor Children includes information about the petitioner's relationship to the minor ward, the reasons why the petitioner is seeking guardianship, and the proposed guardianship arrangement. The Notice of Guardianship of Incapacitated Adults includes similar information but may also include a proposed conservatorship arrangement. In both cases, the petitioner must provide evidence of their qualifications to serve as guardian or conservator.
