Washington Power of Attorney Requirements
Washington’s Uniform Power of Attorney Act (RCW 11.125) sets how a Power of Attorney is signed, what makes it durable, and what an agent must do. One Washington rule surprises many families: a Power of Attorney is not durable unless it says so. Here are the essentials in plain English, each linked to the official Revised Code of Washington.
Based on Washington Uniform Power of Attorney Act, RCW 11.125. Reviewed October 2026. Education, not legal advice — Washington’s requirements are set by state law and can change, so confirm them with an official Washington source or a licensed attorney.
Preparing to serve—or already serving—in Washington?
The National Handbook explains the responsibilities. The National Workbook helps you organize the work. Use the Washington information below to explore requirements, official sources, and available resources.
Requirements depend on your documents and applicable law. Confirm current information with official sources or a qualified professional in your state.
Where is Washington’s Power of Attorney law?
Washington’s financial Power of Attorney law is the Uniform Power of Attorney Act, RCW chapter 11.125, in effect since January 1, 2017. Washington does not include a statutory Power of Attorney form; its only statutory form is an optional agent’s certification (RCW 11.125.430).
How does a Washington Power of Attorney have to be signed?
Under RCW 11.125.050, the principal signs and dates the Power of Attorney, and the signature is either acknowledged before a notary public or attested by two or more competent witnesses who sign in the principal’s presence. The statute excludes certain people as witnesses, including the principal’s home care providers, care providers at an adult family home or long-term care facility where the principal lives, and people related to the principal or the agent by blood, marriage or state registered domestic partnership.
Is a Washington Power of Attorney durable?
Only if it says so. Under RCW 11.125.040, a Washington Power of Attorney terminates upon the incapacity of the principal unless the writing contains durability words, such as “This power of attorney shall not be affected by disability of the principal,” or similar words showing the principal intended the authority to continue. Read your document closely for this language.
When does a Washington Power of Attorney take effect?
Under RCW 11.125.090, a Power of Attorney is effective when signed unless the document says it becomes effective at a future date or on a future event, such as incapacity. The statute explains how incapacity can be determined if the document does not name someone to decide.
What does a Washington agent have to do?
Under RCW 11.125.140, an agent must act according to the principal’s reasonable expectations (or best interest), in good faith, and only within the authority granted. Unless the document says otherwise, the agent must also act loyally, avoid conflicts of interest and keep a record of all receipts, disbursements and transactions. The principal, a guardian, a conservator and certain others can request disclosure of those records.
What happens to a spouse-agent’s authority in a divorce?
Under RCW 11.125.100, unless the Power of Attorney says otherwise, the authority of an agent who is the principal’s spouse or state registered domestic partner ends when an action is filed for dissolution, annulment or legal separation.
What healthcare documents does Washington use?
Washington uses a durable power of attorney for health care, which follows the same signing rules in RCW 11.125.050 and needs durability language, and a health care directive (living will) under RCW 70.122.030, which is signed before a notary or two qualified witnesses. RCW 11.125.400 lists people who may not serve as a healthcare agent, such as the principal’s physicians and employees of the facility where the principal lives, unless they are close family.
This summary is educational and may not reflect the most current law — verify against the current statutes or with a Washington attorney before relying on it.
The universal rules of the role
The exact forms, witnessing, and notarization rules change from state to state — those are in Washington’s essentials above.But the heart of the role is the same everywhere in the U.S. Here’s what always applies.
Your duties as an agent
Every decision is for the principal, never for you. This is the core legal duty of an agent, everywhere.
Never mix the principal’s funds with your own. Use their accounts for their expenses, and don’t borrow or lend to yourself.
Track every transaction, receipt, and major decision. Good records protect the principal — and protect you if anyone ever asks.
You can only do what the Power of Attorney actually authorizes. If it isn’t granted in the document, you don’t have the authority.
Follow what they’d want, preserve their existing estate plan where you can, and avoid anything that benefits you at their expense.
What a Power of Attorney can’t do
A Power of Attorney works only while the principal is alive. The moment they pass, it ends and the will and executor (or trustee) take over.
An agent cannot make or rewrite the principal’s will, and generally can’t change beneficiary designations unless the document specifically allows it.
Powers not written into the document — like making gifts or changing accounts — usually aren’t allowed. When in doubt, it’s probably not authorized.
When you sign correctly as the agent (not personally), you’re acting for them — you don’t take on their debts by serving.
How to sign as an agent
Always sign in your representative capacity — never just your own name on the principal’s business. A safe format anywhere is “Jane Doe, as agent for John Doe” (some institutions prefer “John Doe by Jane Doe, agent”). Signing your name alone can make you personally liable; signing as the agent makes clear you’re acting for them.
When the authority ends
- The principal revokes it — they can, at any time, as long as they’re competent.
- The principal dies — authority passes to the will or trust.
- A court appoints a guardian or conservator, or the document’s own end date or condition is reached.
One key distinction, everywhere: a durable Power of Attorney keeps working if the principal becomes incapacitated; a non-durable one ends at incapacity. Whether yours is durable is stated in the document itself.
