Types of Adult Guardianship in Washington: Powers and Duties of a Guardian
The legal landscape for protecting vulnerable adults in Washington underwent a systemic transformation on January 1, 2022, with the implementation of the Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act (UGA). This rights-based framework, codified as RCW 11.130, shifted the focus from a paternalistic model to one that prioritizes the autonomy and preferences of the individual. At View Ridge Law, our team provides practical solutions with a holistic outlook to help you navigate these sensitive transitions.
The Presumption of Legal Capacity
Under the UGA, every adult is presumed to have the legal capacity to manage their own affairs. For the state to intervene, a court must find by “clear, cogent, and convincing evidence” that an individual is unable to evaluate information or communicate decisions, even with supportive services. This legal standard ensures that a medical diagnosis alone does not automatically strip an individual of their civil rights.
Distinguishing Guardianship and Conservatorship
Washington law bifurcates the traditional role of a “guardian” into two distinct functional categories.
Guardianship of the Person:
A guardian is appointed to assist an individual with essential needs related to physical health, safety, and self-care. This includes making choices about where a person lives, their medical treatment, and their daily activities.
Conservatorship of the Estate:
A conservator is a fiduciary appointed strictly to manage property and financial affairs. This is appropriate when a person can no longer manage their money due to cognitive impairment, such as advanced dementia. A single person can serve in both roles, but the court often keeps them separate to ensure the “least restrictive” intervention.
Plenary, Limited, and Emergency Arrangements
The UGA requires that any court-appointed protection be tailored to the specific needs of the adult.
- Full (Plenary) Guardianship: The guardian assumes authority for all rights listed in state law.
- Limited Guardianship: The court’s preferred method, where specific rights—such as the right to vote or marry—are explicitly preserved unless evidence demands their removal.
- Emergency Guardianship: Designed for acute crises, these appointments are valid for only 60 days to prevent immediate harm.
- Other Protective Arrangements (OPA): A “single-shot” court order for a specific transaction, such as authorizing a medical procedure, without an ongoing guardianship.
The Fiduciary Duties of a Guardian
Guardians and conservators are held to the highest standard of loyalty and good faith.
Substituted Judgment Standard:
A guardian’s primary duty is to make decisions they believe the adult would make if they were able, prioritizing the individual’s documented values and prior directions. Only if wishes cannot be ascertained may the guardian act in the adult’s “best interest”.
Mandatory Reporting:
Fiduciaries must file regular reports, typically annually, to ensure the individual is receiving proper care and that finances are handled transparently.
