How to Get Power of Attorney in Washington State

To get a power of attorney in Washington State, you sign a written document naming an agent and describing the authority you’re granting, then either have your signature notarized or witnessed by two qualifying witnesses. The requirements sit in chapter 11.125 of the Revised Code of Washington, the state’s Uniform Power of Attorney Act. You must be at least 18 and mentally capable of understanding what you’re signing at the moment you sign it.

The document itself is not complicated. Getting the details right is what separates a power of attorney that works from one a bank refuses to honor.

Confirm You Can Sign

Washington calls the person creating the document the “principal.” You need to be 18 and you need capacity, meaning you understand what authority you’re handing over and to whom. Capacity is judged at the moment of signing, not by your general condition before or after.

For most people this is a non-issue. For older adults, anyone with a recent diagnosis affecting cognition, or anyone whose family situation could produce a challenge later, capacity is worth documenting. The Washington Supreme Court has looked closely at what the principal understood at the time of signing, including one case where a notary refused to notarize because the principal appeared disoriented.¹ A physician’s note dated close to your signing can head off a fight later.

Decide What Kind of Authority You Are Granting

The type of power of attorney you choose determines what your agent can do, when their authority begins, and when it ends. Most people creating a power of attorney for estate planning purposes want a durable one; the other types exist for narrower situations.

Durable

A durable power of attorney continues to work if you later become incapacitated. That’s usually the whole point. Under RCW 11.125.100, a power of attorney that isn’t made durable terminates when the principal becomes incapacitated, which is precisely when families most need an agent in place.² To make it durable, the document must state that the agent’s authority continues even if you become incapacitated.

General

A general power of attorney gives your agent broad authority over your financial and property affairs: bank accounts, bill paying, buying and selling property, investments. If you want that authority to survive incapacity, the document also has to be durable. General authority without durability language stops the moment you cannot manage your own affairs.

Limited

A limited (or “special”) power of attorney restricts your agent to a specific task, such as closing on a house sale while you’re out of the country or handling one particular account. The document spells out exactly what the agent can and cannot do, and the authority ends when the task is done or on a date you set. This is the right tool when you need someone to step in for a defined purpose and nothing more.

Springing

A springing power of attorney takes effect only when a triggering event occurs, usually the principal’s incapacity. The document should say who decides the trigger has been met. Most springing powers require one or two physicians to certify in writing that the principal can no longer manage their affairs. The appeal is that the agent has no authority while you’re healthy; the drawback is that proving the trigger condition to a bank in a hurry can cause delays exactly when your agent needs to act.

Choose Your Agent, and a Backup

Your agent is the person who will sign your name, move your money, and deal with your financial institutions. Washington law imposes no formal qualifications, but the practical demands are real. Your agent needs to be organized enough to keep records, willing to push back on banks when necessary, and honest enough to resist the temptations that come with controlling someone else’s money.

Most people name a spouse, an adult child, or a close friend. Naming co-agents is possible but tends to slow things down because institutions may require both signatures on every transaction. A cleaner setup is a primary agent plus one or two successor agents who step in if the primary can’t serve. RCW 11.125.100 confirms that a power of attorney terminates if the sole agent dies, becomes incapacitated, or resigns and no successor is named.² Naming a backup is the difference between a working document and one that dies with your first choice.

Once appointed, your agent owes you a fiduciary duty: they must act in good faith, keep records, stay within the authority you granted, and put your interests ahead of their own. This is enforceable in court, not just an expectation. If you are also naming your agent to make health care decisions, be aware those authorities are usually handled through a separate advance directive under Washington’s Natural Death Act (chapter 70.122 RCW), though RCW 11.125.400 does allow health care authority within a power of attorney if the document is drafted for it. The person best suited to manage your money is not always the person best suited to make medical calls under pressure, and you can name different agents for each role.

Sign It Correctly

This is where homemade powers of attorney most often fail. RCW 11.125.050 requires the principal to sign and date the document, and the signature must be either acknowledged before a notary public or witnessed by at least two competent witnesses.³ You need one path or the other. You do not need both.

If you use witnesses, they must qualify. A witness cannot be a home care provider for the principal, a care provider at a facility where the principal lives, or related to the principal or the agent by blood, marriage, or registered domestic partnership.³ These restrictions exist because the people with daily access to a vulnerable adult are also the people most likely to exert undue influence.

Even though the statute treats notarization and witnesses as equal options, notarize if you can. Banks, title companies, and county recorders are used to verifying notarized signatures and sometimes balk at witness-only documents even when they are legally valid. If your power of attorney might ever touch real estate, notarization is effectively required, because county recorders typically will not accept an unnotarized document. Notary fees for a signature acknowledgment are usually modest.

Make Sure the Document Will Actually Be Accepted

A valid power of attorney does not help if the bank in front of your agent won’t honor it. Washington addresses that friction in RCW 11.125.200: a person presented with a properly notarized power of attorney must either accept it or request a certification or translation within seven business days, and once a requested certification or translation is provided, must accept within five additional business days. Institutions cannot force you to use their own proprietary form if the power of attorney you have already covers the authority in question.⁴

An institution that wrongfully refuses can be ordered by a court to accept the document and to pay the agent’s reasonable attorney’s fees and costs. Refusal is still permitted where the institution has a good-faith belief that the power of attorney is invalid, that the agent is exceeding their authority, or that the principal may be subject to abuse or exploitation.⁴

Federal Agencies Do Not Recognize a State Power of Attorney

This trips up a lot of families. The Social Security Administration does not accept a state power of attorney for managing someone’s benefits. To handle a parent’s Social Security or SSI, you have to apply through SSA to become a “representative payee,” which is a separate process with its own application and approval.⁵ The IRS has its own system as well: to represent someone before the IRS, you file Form 2848, and the representative must be eligible to practice before the IRS, such as an attorney, CPA, or enrolled agent.⁶ Plan for both separately.

Storage and Recording

Store the original somewhere secure but accessible. A fireproof home safe works. A safe deposit box can be counterproductive because your agent may need the power of attorney to get into the box in the first place. Give copies to your agent, your attorney, and any family members who need to know the document exists. If the power of attorney will be used for real estate, consider recording it with the county auditor in the county where the property sits, which creates a public record title companies can verify without chasing down the original. For major financial accounts, sending each institution a copy in advance can head off delays when your agent later needs to act quickly.

Changing or Ending the Document Later

You can revoke your power of attorney at any time as long as you have the capacity to do so. Under RCW 11.125.100, a power of attorney also terminates when its stated purpose is accomplished, when the document itself says it ends, or when the principal dies.² Revocation should be in writing, and you have to notify both your agent and any third party that has been relying on the document. A bank that never learns of the revocation may reasonably keep honoring the old power of attorney.

One trap catches people who update their documents: signing a new power of attorney does not automatically revoke an earlier one. Unless the new document explicitly says it revokes all prior powers of attorney, both could remain active and create confusion over who has authority.² If you’re replacing an old one, include a revocation clause in the new document and collect or destroy the old originals where you can.

And once the principal dies, the power of attorney is over. Authority passes to the personal representative named in the will or appointed by the probate court, not to the agent. Families sometimes assume the agent can keep paying bills or closing accounts after death; that assumption is how estates end up in front of a judge.
