Guardianship vs power of attorney

Updated 2026-10-16 · Expert review in progress

The short answer

A power of attorney is a document you sign while you can, naming someone you choose to act for you. Guardianship is a court process that starts after you can't decide, where a judge appoints someone and supervises them. In Washington, a working power of attorney is one of the alternatives a court must consider first.

Both of these put another person in a position to decide for you. That is where the likeness ends. One is a choice you make at your kitchen table. The other is a decision a judge makes in a courtroom.

This page sets guardianship vs power of attorney side by side, using Washington's law as the worked example. It is part of our guide to what happens if you can't speak for yourself, which covers the whole stretch of incapacity.

What is a power of attorney?

A power of attorney is a signed document. In it you name someone, called your agent, to act for you. Most people sign two: a financial power of attorney for money and property, and a medical power of attorney for health care decisions.

In Washington you sign and date it before a notary, or before two qualified witnesses (RCW 11.125.050). It must also say it keeps working if you become incapacitated. Without that wording, it ends at incapacity (RCW 11.125.040). Our post on the durable power of attorney explains that rule.

Your agent is a fiduciary: legally required to act in your interest and follow what you wrote. In Washington an agent must act on your reasonable expectations where known, act in good faith and keep records (RCW 11.125.140).

What is guardianship?

Guardianship is a court appointment. Washington's law calls a guardian someone "appointed by the court to make decisions with respect to the personal affairs of an individual" (RCW 11.130.010). Money and property are handled by a different court appointee, a conservator. Our post on conservatorship vs power of attorney covers that side.

A guardian may decide where the person lives and consent to health care, unless the court limits those powers (RCW 11.130.330). The guardian is a fiduciary too. They must make the decision they reasonably believe the person would make, based on that person's known values and wishes (RCW 11.130.325).

How does each one get started?

A power of attorney starts with you. You choose the person, sign the document, and hand over a copy. In Washington it takes effect when signed unless it names a later date or event (RCW 11.125.090).

Guardianship starts with a petition. Any person interested in an adult's welfare can file one (RCW 11.130.270). From there, Washington's process has several required steps:

A court visitor is appointed. The visitor interviews the person, visits their home and reports to the court (RCW 11.130.280).
A professional evaluation is ordered. A physician, psychologist, nurse practitioner or physician assistant examines the person (RCW 11.130.290).
Notice goes out. The person is served with the petition and a plain statement of their rights, including the right to a lawyer and to a jury trial (RCW 11.130.275).
A hearing is held. The person generally must attend, in person or by video, and may present evidence (RCW 11.130.295).

The same notice statute says petitions must be heard within 60 days unless the court extends that for good cause. These steps protect the person. They also mean a guardian is not there the day a crisis starts.

What does a court have to find?

The bar is high on purpose. A Washington judge may appoint a guardian only on clear and convincing evidence of three things (RCW 11.130.265):

The person can't meet essential needs for health, safety or self-care, even with support.
A guardian is needed to prevent significant risk of harm.
A less restrictive alternative won't meet those needs.

Washington's definition of a less restrictive alternative expressly includes a power of attorney for health care or for finances (RCW 11.130.010). So a working power of attorney is often the reason a guardianship isn't needed.

The court must also give only the powers the person actually needs. It may not order a full guardianship if a limited one would do (RCW 11.130.265).

Guardianship vs power of attorney, side by side

Item	Power of attorney	Guardianship
Who picks the person	You	A judge, using a priority list (RCW 11.130.305)
When it's set up	While you can still sign	After someone files a petition
Court steps	None to create it	Visitor, evaluation, notice, hearing
Scope	Whatever your document grants	Only the powers the court orders
Reporting	Records kept; shared on request (RCW 11.125.140)	Plans and periodic reports to the court (RCW 11.130.345)
Privacy	A private document	The existence of the guardianship is a public record (RCW 11.130.300)
Changing it	You can revoke it while you have capacity	Only the court can end or change it (RCW 11.130.355)

Court supervision has real value when nobody else is watching. It is also more formal. In Washington, the order sets a report schedule that can be annual, biennial or triennial (RCW 11.130.310).

What happens if both exist?

Sometimes a court appoints a guardian for someone who already signed a power of attorney. Washington's law is clear about who comes first.

A guardian can't revoke or amend the person's power of attorney. If a health care power of attorney is in effect, the agent's health care decisions take precedence over the guardian's, unless a court orders otherwise. The same goes for a financial agent acting within their authority (RCW 11.130.335).

The same statute does let the court itself revoke or amend a power of attorney. That's the safety valve if an agent isn't doing the job.

Does your choice still count in court?

Yes. If a court ever has to choose a guardian, Washington's priority list puts someone you nominated, including in a power of attorney, ahead of a spouse or relatives. Your health care agent comes next (RCW 11.130.305).

The power of attorney statute goes further. When you nominate a guardian in your power of attorney, the court must follow your most recent nomination except for good cause or disqualification (RCW 11.125.080). Our post on how to avoid guardianship shows how to put that nomination in writing.

Here is a typical case, a composite. Ruth, 74, signed both powers of attorney years ago, naming her friend Carol and a backup. When a stroke left Ruth unable to speak for a few weeks, Carol paid the bills, fed Ruth's cat and talked with her doctors. There was no petition and no hearing, because Ruth had already decided.

Which one fits your situation?

If this is true	Usually the path
You can still understand and sign documents	Sign durable financial and medical powers of attorney now
You signed powers of attorney and the agent can act	Your agent acts; no court needed
Nothing is signed and you can no longer decide	A court process such as guardianship or conservatorship
An agent is misusing their authority	A court can review the agent and appoint a guardian or conservator if needed

If the right person to name isn't obvious, you still have options. Some people name a friend, others a professional or a trust company as first choice or as backup. Our guide to choosing professional help compares those routes. A Kinly membership includes both powers of attorney, with Trella Trust Company available in either role.

Common questions

Is a power of attorney better than guardianship?

For most people who can still sign, a power of attorney is simpler. You choose the person, there's no court process to create it, and it can be ready the day you need it. Guardianship exists for when nothing was signed or the arrangements in place aren't working.

Can a guardian override my power of attorney in Washington?

Not on their own. A Washington guardian can't revoke or amend your power of attorney, and your agent's decisions within their authority take precedence. Only the court can revoke or change it.

Can a power of attorney prevent guardianship?

Often, yes. Washington courts may appoint a guardian only if a less restrictive alternative won't meet the person's needs, and a power of attorney counts as one. It isn't a guarantee, especially if the agent can't or won't act, so naming a backup matters.

Who can be a guardian in Washington?

The court follows a priority list. First comes a guardian already acting in another state, then someone the person nominated, then their health care agent. After that come a spouse or domestic partner, a caring relative or friend, and a certified professional guardian. The court can depart from the list in the person's best interest.

Does guardianship happen quickly?

Not usually. Washington requires a court visitor, a professional evaluation, notice and a hearing, and petitions are to be heard within 60 days unless extended. Emergency guardianships exist for urgent situations, but they are short and limited.
