Requirements one by one
Governing law
Washington's Uniform Power of Attorney Act (§§ 11.125.010-.903) applies to financial powers of attorney, with exceptions for powers coupled with an interest, entity voting or management proxies, and government-prescribed forms (§ 11.125.030).
Who must sign
If the principal cannot sign, § 11.125.050(2) accepts a mark under § 11.12.030. If the principal cannot make a mark, § 64.08.100 allows the principal to direct the acknowledging officer orally to sign on the principal's behalf.
Notarization
Acknowledgment before a notary or other authorized officer creates a presumption that the principal's signature is genuine (§ 11.125.050(3)).
Springing POA allowed?
The principal may designate a person to determine in writing that the triggering event has occurred. If incapacity is the trigger and a named determiner is unable or unwilling to act, § 11.125.090(3) specifies a written determination by an unrelated examining physician or licensed psychologist, or a judge or appropriate official for the alternate incapacity grounds.
Real estate extras
An instrument granting power to convey real property is expressly excluded from the definition of a “conveyance” in § 65.08.060(3). The deed or other conveyance the agent executes is a separate instrument: § 65.08.070(1) allows an acknowledged conveyance to be recorded and states the consequence of failing to record against a later good-faith purchaser or mortgagee. Section 11.125.270 describes the agent's real-property authority once granted.
What trips people up
- Durability needs words in the document. Section 11.125.040 terminates authority upon incapacity unless the writing says authority survives or begins with disability, or uses similar words showing that intent.
- Care providers and relatives cannot witness. The witness route excludes the specified home and facility care providers and people related to the principal or agent by blood, marriage, or state registered domestic partnership (§ 11.125.050(1)).
- The vehicle exception is narrow. The exception in § 11.125.050(4), added by 2026 c 101, allows a signed and dated limited power used solely to transfer vehicle ownership to an insurer after payment of damages without a notarized signature, and permits electronic signing and printing. It does not rewrite the ordinary financial POA rule.
Common questions
Can an agent use a copy? Except where another statute provides otherwise, a photocopy or electronically transmitted copy has the same effect as the original (§ 11.125.060(4)).
Is the optional form in the chapter a POA form for me to sign? No. Section 11.125.430 provides an optional form for the agent to certify facts about an existing power of attorney.
