Updated August 3, 2026. Quick answer: RCW 11.125.050(1): the principal’s signature must be EITHER acknowledged before a notary public (or other individual authorized to take acknowledgments) OR attested by two or more qualifying competent witnesses — these are alternative valid methods, not cumulative (you do not need both). This state has no statutory form. A power of attorney here must say it is durable, or it ends at incapacity — which is the moment it was written for.

Washington power of attorney form: what the statute says
Each line is quoted from the Washington statute itself.
- Execution. RCW 11.125.050(1): “A power of attorney must be signed and dated by the principal, and the signature must be either acknowledged before a notary public or other individual authorized by law to take acknowledgments, or attested by two or more competent witnesses…”
- Witnesses. RCW 11.125.050(1): the signature may instead be “…attested by two or more competent witnesses who are neither home care providers for the principal nor care providers at an adult family home or long-term care facility in which the principal resides, and who are unrelated to the principal or agent by blood, marriage, or state registered domestic partnership…” so witnesses are an alternative to a notary.
- Recording for real estate. RCW 65.04.030(1): “Deeds, grants and transfers of real property, mortgages and releases of mortgages of real estate, instruments or agreements relating to community or separate property, powers of attorney to convey real estate, and leases which have been acknowledged or proved…”

What decides whether the document is valid
RCW 11.125.050(1): the principal’s signature must be EITHER acknowledged before a notary public (or other individual authorized to take acknowledgments) OR attested by two or more qualifying competent witnesses — these are alternative valid methods, not cumulative (you do not need both). Get this wrong and the document is not merely weak — it may be void, and you will find out at the moment somebody needs to use it.
Who may not witness: If the witness route is used, witnesses may not be home care providers for the principal, care providers at an adult family home or long-term care facility where the principal resides, or persons related to the principal or agent by blood, marriage, or state registered domestic partnership (RCW 11.125.050(1)). This is the condition that most often fails in practice, because the people in the room are usually the people with an interest.
There is no statutory form
Washington does not put a form in its statute, so there is nothing official to copy. The requirements above still govern whatever document you use.
If the free form does not fit your situation
This state has no statutory form to copy, which is the case where a drafted document earns its keep. LawDepot builds a state-specific power of attorney executed under this state’s witnessing and notary rules. Where the estate is complex or a dispute is likely, see a lawyer instead.

Durability — the point most people get wrong
Here a power of attorney must state that it is durable. Without that language it ends exactly when incapacity begins — which is the situation it was almost certainly written for. This is the single most consequential drafting point in this state.
Why a springing power often fails when it is needed, and why durable is usually the better default.
If a bank refuses it
Washington addresses this by statute: Yes. RCW 11.125.200: a person must accept an acknowledged POA, or request a certification/translation, no later than 7 business days after presentation; if requested, must accept within 5 business days after receipt. Wrongful refusal is subject to a court order mandating acceptance and liability for reasonable attorneys’ fees and costs, subject to listed exceptions.
What the form does not solve
- Social Security will not accept it. No power of attorney works there — a representative-payee application is the only route.
- It has to be signed while capacity is intact. The day that closes, the alternative is a court.
- Name a successor agent. A document whose only named agent has died or declined does nothing — how to choose when there is no obvious person.
