Power of attorney in Washington: rules, signing, who to name
The short answer
A Washington financial power of attorney keeps working after you lose capacity only if it says so in writing. You sign and date it, then either have it notarized or signed by two qualified witnesses. A bank shown a notarized power of attorney must accept it or ask for a certification within seven business days.
A financial power of attorney lets someone you trust pay your bills, talk to the bank and look after your money if you can't. Washington has its own rules for writing and signing one, and a couple of them catch people off guard.
This page walks through those rules in plain words. It is one of our state-by-state estate planning guides. If the idea is new to you, start with what a power of attorney does, then come back here.
Is a Washington power of attorney durable?
Only if it says so. This is the most important Washington rule to know. A power of attorney ends when you become incapacitated unless it contains words showing you want it to continue (RCW 11.125.040).
The statute gives two examples of that wording: "This power of attorney shall not be affected by disability of the principal," or "This power of attorney shall become effective upon the disability of the principal." Similar words that show the same intent also work.
Without language like this, the document can stop working at the very moment your family needs it. The second example creates a springing power of attorney, one that starts only when you lose capacity. Our post on springing powers of attorney explains the trade-offs, and durable power of attorney covers why durability matters.
How do I sign one in Washington?
You sign and date the document. Then you have a choice: acknowledge it before a notary, or have two qualified witnesses sign it (RCW 11.125.050).
Witnesses have to meet certain rules. A witness can't be:
- Your home care provider.
- A care provider at an adult family home or long-term care facility where you live.
- Related to you or to your agent by blood, marriage or state registered domestic partnership.
A notary is usually the simpler path, and it matters for another reason. The bank acceptance rule below applies to a notarized power of attorney. If you can, have it notarized even if you also use witnesses.
Washington has no official statutory form for a financial power of attorney. Any document that meets the signing rules and uses durability wording is valid.
Will my bank have to accept it?
Washington adopted the Uniform Power of Attorney Act, and it gives notarized documents real weight (RCW 11.125.010).
A bank or other person shown a notarized power of attorney has seven business days to do one of two things: accept it, or ask for a certification or a translation. If they ask, they then have five business days after receiving it to accept. They can't insist that you sign their own form instead (RCW 11.125.200).
There are exceptions. A bank may refuse if it believes in good faith that the document isn't valid, or if it has reported suspected abuse to the state's social services department. A wrongful refusal can lead to a court order and an award of attorneys' fees.
Even with this rule, a little groundwork helps:
- Give your bank and investment firm a copy while you are well.
- Ask whether they need anything else on file.
- Keep the original somewhere your agent can reach, with a note saying where.
What can my agent do, and what can't they?
Your document sets the scope. A broad financial power of attorney usually covers everyday money matters: paying the electric bill, depositing a pension, filing taxes, getting the roof fixed.
Your agent is a fiduciary: legally required to act in your interest and follow what you wrote.
Some powers only exist in Washington if you spell them out. A general grant is not enough for these (RCW 11.125.240):
| Power | Included in a general grant? | What Washington requires |
|---|---|---|
| Create, change or revoke a living trust | No | An express grant in the power of attorney |
| Make gifts | No | An express grant |
| Change beneficiary designations or survivorship rights | No | An express grant |
| Create, change or revoke a community property agreement | No | An express grant |
| Hand your agent's authority to someone else | No | An express grant |
| Make health care decisions | No | An express grant |
If you have a living trust, there is a second hurdle. In Washington, an agent can act on your trust only if the power of attorney expressly allows it and doing so is consistent with the trust (RCW 11.103.030). Our post on what a living trust is explains how the two documents work together.
The last row matters too. Washington has no separate health care proxy law, so medical authority goes in a power of attorney with its own express grant. Our Washington medical power of attorney guide covers that document and its own witness rules.
Who should I name as my agent?
The real questions are practical. Is this person good with money and paperwork? Do they live close enough to go to the bank, or to the house if a pipe bursts? Will they keep records and answer your family's questions?
A short checklist when you choose:
- Trust: would you hand them your checkbook today?
- Distance: can they get to your home, your bank and your mail?
- Time: do they have room in their life for this, maybe for years?
- Backup: who steps in if your first choice can't? Our post on having a backup in every role explains why this matters.
Many people choose a sister, a niece or a longtime friend. Our post on naming a friend as power of attorney covers what to talk through first.
Here is a typical case, a composite. Joan is 70 and lives in Spokane. Her daughter is in Denver. Joan names her friend Diane, who already has a key and waters the tomatoes when Joan travels, as her agent, with her daughter as backup. She has it notarized and drops a copy at her credit union.
What if I never sign one?
If you lose capacity without a durable power of attorney, your family may need to ask a court to appoint a guardian or conservator to handle your money. That takes time and money, and a judge decides who serves. Our post on conservatorship vs power of attorney explains the difference.
Some people would like a professional standing by, either first or behind a friend. A Kinly membership includes a financial power of attorney written for your state, and Trella Trust Company, a Washington State chartered trust company, can be named in the role. You set the order.
Your power of attorney ends at death, when your personal representative takes over. Our Washington probate and small estates guide covers what happens then.
Signing checklist
| Step | What to check |
|---|---|
| Durability wording | The document says it is not affected by your disability, or starts on your disability |
| Signature | You sign and date it |
| Notary or witnesses | A notary acknowledges it, or two qualified witnesses sign (a notary is best for bank acceptance) |
| Witness rules | No relatives of you or your agent, and no home care or facility care providers |
| Special powers | Trust changes, gifts, beneficiary changes and health care each spelled out if you want them |
| Backup agent | A second person named in case your first choice can't serve |
| Copies | Bank and investment firm have a copy; your agent knows where the original is |
Common questions
Is a Washington power of attorney durable automatically?
No. It ends when you become incapacitated unless it contains words saying it continues, or that it starts on your disability. Check that your document has that wording.
Does a power of attorney need to be notarized in Washington?
Not always. It must be notarized or signed by two qualified witnesses. Notarizing is usually wise, because the bank acceptance rule applies to notarized documents.
Does my bank have to accept my Washington power of attorney?
If it is notarized, the bank must accept it or ask for a certification or translation within seven business days. It can't demand its own form. There are exceptions, such as a good-faith belief that the document isn't valid.
Can my financial agent make medical decisions in Washington?
Only if the power of attorney expressly grants health care authority. Many people sign a separate document for health care so the two roles stay clear.
Can my agent change my living trust?
Only if the power of attorney expressly allows it and it is consistent with the trust. A general grant of financial powers is not enough.
