How to Revoke a Power of Attorney in Washington State

Circumstances change. The agent you trusted three years ago may no longer be the right person to manage your finances or healthcare decisions. Washington law gives you the absolute right to revoke a power of attorney at any time, as long as you still have mental capacity. But the process has specific requirements you need to follow to make the revocation effective against everyone who matters.

The Legal Basis for Revocation

Under RCW 11.125.100, a principal may revoke a power of attorney at any time while they retain mental capacity. There is no waiting period, no court approval, and no requirement to explain why.

Capacity is the only prerequisite. If you understand what a power of attorney is, who your current agent is, and what revoking it means, you have sufficient capacity to revoke.

Steps to Revoke Properly

Step 1: Write the revocation. While verbal revocation is technically possible under Washington law, written revocation is the only practical option. A verbal statement won't convince your bank to stop honoring the old document. Draft a written revocation statement that identifies the original POA by date, names the agent whose authority you're terminating, and states clearly that the prior POA is revoked in full.

Step 2: Notarize the revocation. This isn't strictly required by statute, but it's essential for enforcement. Banks and financial institutions that previously accepted the original notarized POA will expect notarized proof of revocation.

Step 3: Deliver the revocation to the agent. Send a copy of the written revocation directly to your agent. Use a method that creates proof of delivery — certified mail with return receipt, or hand delivery with a signed acknowledgment.

Step 4: Notify all third parties. This is the step most people miss. Send copies of the revocation to every institution that has a copy of or has previously relied on the original POA: banks, credit unions, brokerage firms, insurance companies, healthcare providers, and the county auditor if the original POA was recorded for real estate purposes.

Until a third party receives actual notice of revocation, they are legally protected in relying on the original document. An undelivered revocation doesn't prevent an agent from continuing to act.

Step 5: If a real estate POA was recorded, record the revocation. The revocation should be recorded with the county auditor in any county where the original POA was recorded. This puts the public land records on notice that the agent no longer has authority over real property.

The New-Document Trap

A common misconception: signing a new power of attorney automatically revokes the old one. It doesn't. Under RCW 11.125.100, executing a new POA does not revoke a prior document unless the new one explicitly states that all previous powers of attorney are revoked.

If you sign a new POA without this revocation clause, you now have two agents — potentially with conflicting authority — both holding valid documents.

Divorce and Automatic Revocation

Washington law provides one automatic revocation scenario. If your spouse or registered domestic partner is named as your agent and you file a petition for divorce, dissolution, or legal separation, their authority as agent terminates automatically under the statute. No separate revocation is needed.

This protection doesn't extend to other relationships. If you named a sibling, adult child, or friend as agent and the relationship deteriorates, you must revoke manually.

When to Get Help

If your agent has been actively managing financial accounts and you're concerned about potential misuse, consider consulting an attorney before revoking. You may want to petition the court for an accounting under RCW 11.125.160 to understand what the agent has done before terminating their authority. Once revoked, obtaining records of the agent's past transactions becomes significantly harder.
