The Washington Oath of Guardian (OA) is a document created to protect the interests of vulnerable adults in the state of Washington. It is a legal document that is signed by a guardian, who agrees to take responsibility for making decisions on behalf of the person who is unable to make decisions for themselves. The document outlines the guardian's duties, including their responsibility to provide for the person's physical, mental, and emotional well-being. There are two types of Washington Oath of Guardian (OA): a Temporary Guardianship and a Permanent Guardianship. In a Temporary Guardianship, a guardian is appointed to make decisions on behalf of the person for a limited period of time. A Permanent Guardianship is a more long-term arrangement in which the guardian is appointed to make decisions on behalf of the person indefinitely.
