Washington Letters of Guardianship or Limited Guardianship are legal documents that appoint a guardian or limited guardian to manage the affairs of a person who is unable to do so for themselves. This may include minors, the elderly, those with disabilities, or those with mental illness. There are two types of Washington Letters of Guardianship or Limited Guardianship: Full Guardianship and Limited Guardianship. Full Guardianship is a legal document granting a guardian full decision-making authority over the ward's personal and financial matters. This type of guardianship can be used for a minor or for an adult who is unable to care for themselves due to physical or mental disability. Limited Guardianship is a legal document granting a guardian limited decision-making authority over the ward's personal and financial matters. This type of guardianship is usually used for an adult who is unable to care for themselves due to physical or mental disability, but who still has some capacity to make decisions. Limited Guardianship allows the guardian to make decisions on behalf of the ward in a limited capacity, such as managing their finances, making medical decisions, or living arrangements. Washington Letters of Guardianship or Limited Guardianship must be approved by a court in order to become legally binding. The court will consider the best interests of the ward, the ability of the guardian to make decisions on behalf of the ward, and the wishes of the ward if they are capable of expressing them.
