How Do I Terminate a Guardianship in Washington?

A guardianship is meant to last only as long as the person actually needs it, and Washington law gives families a clear path to end one when circumstances change. If you are asking how to close out a guardianship in Snohomish County, the short answer is that you file a petition with the superior court and ask the court to end the arrangement because the reason for it no longer exists or because ending it serves the protected person's best interest.

Start With the Right Question: Minor or Adult?

Washington reorganized its entire guardianship system in 2022 under the Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act, found in chapter 11.130 RCW. The first thing that matters is whether the guardianship is over a minor or an adult, because the two follow different sections and different logic. Under RCW 11.130.010, a guardian is the person appointed to make decisions about someone's personal affairs, while a conservator handles property and finances. This article focuses on ending a guardianship of the person. If you are dealing with a conservatorship over money and property, similar principles apply but the governing sections differ.

Ending a Minor Guardianship

A guardianship over a child often ends on its own. Washington law says a minor guardianship terminates automatically when the minor dies, is adopted, becomes emancipated, or reaches the age of majority, which in Washington is eighteen. That rule lives in RCW 11.130.240. So if a grandparent has been serving as guardian for a grandchild, that authority simply expires when the child turns eighteen without anyone needing to file paperwork to make it happen.

The more common situation is a parent who has gotten back on their feet and wants to resume caring for their child before the child grows up. The same section, RCW 11.130.240, allows the minor, a parent, or another person interested in the child's welfare to petition the court to terminate the guardianship, modify it, or replace the guardian. The court will end the guardianship when it finds that the original basis for appointment under RCW 11.130.185 no longer exists. Under that basis section, a guardianship was proper only where each parent consented, parental rights had been terminated, or there was clear and convincing evidence that no parent was willing or able to exercise parenting functions. When that condition has changed, the foundation for the guardianship is gone.

There is an important protection built into the statute. Even when the original basis no longer exists, the court will not automatically hand the child back if doing so would harm the child. RCW 11.130.240 directs the court to keep the guardianship in place if termination would be harmful to the minor and the child's interest in continuing the guardianship outweighs a parent's interest in regaining decision-making authority. The court can also order transitional arrangements to help the child move smoothly from the guardian's home back to a parent, because a child's stability is treated as the priority throughout.

Ending an Adult Guardianship

For an adult, the path runs through RCW 11.130.355, titled termination or modification of guardianship for an adult. The adult under guardianship, the guardian, or anyone interested in the adult's welfare may petition the court to end the guardianship on the ground that a basis for appointment under RCW 11.130.265 no longer exists, that termination would be in the adult's best interest, or for other good cause. That same petition can ask instead for a modification, meaning the guardianship stays in place but the guardian's powers are reduced to match what the person actually needs.

Under RCW 11.130.265, a guardian for an adult was appointed only where clear and convincing evidence showed the person could not meet essential requirements for physical health, safety, or self-care, that appointment was necessary to prevent significant risk of harm, and that no less restrictive alternative would work. If a person has recovered, stabilized, or gained supports that meet those needs in a less restrictive way, the reason for the guardianship falls away.

Washington law tilts strongly toward restoring independence. RCW 11.130.355 provides that once a petitioner presents prima facie evidence supporting termination, the court must order termination unless someone proves that a basis for appointment still exists. In plain terms, the burden shifts. The person asking to keep the guardianship in place has to justify it, rather than the person seeking freedom having to prove they no longer need protection. The statute also requires the court to modify a guardian's powers whenever those powers have become excessive or inadequate because the adult's abilities, supports, or circumstances have changed.

What the Process Looks Like in Practice

For both minor and adult guardianships, you begin by filing a petition in the superior court that has been overseeing the case, which for local families is the Snohomish County Superior Court. The petition explains what has changed and why the guardianship should end or be narrowed. Notice goes out to the people the statute requires, including the protected person, the current guardian, and others the court identifies. The court then holds a hearing. For an adult, RCW 11.130.355 requires the court to follow the same safeguards that applied when the guardianship was first created, including the adult's right to choose an attorney. The court weighs the evidence and enters an order either ending the guardianship, modifying it, or leaving it in place.

Because these petitions turn on specific facts and the statute sets particular standards and burdens, families often find it helpful to have the paperwork and the argument prepared carefully so the hearing goes smoothly.
