Washington Healthcare Power of Attorney Requirements
Washington never enacted a stand-alone health care power of attorney law.
Introduction
Washington never enacted a stand-alone health care power of attorney law. This authority instead comes from the same statute that governs Washington's general and financial powers of attorney, the Uniform Power of Attorney Act, Revised Code of Washington Chapter 11.125, effective 2017, and it works by letting you name someone you trust, called an agent, to make health care decisions for you if you are ever unable to make them yourself. That shared statute means the execution rules are identical no matter what kind of authority you grant. You sign the document either before a notary public, or in front of two witnesses who are not your home care or facility care providers and are not related to you or your agent. Health care decision-making authority itself, however, is not automatic. Washington law requires you to expressly state, in the document, that you are granting your agent authority over health care decisions. You also control when your agent's authority begins. Under Washington law, a power of attorney takes effect the moment you sign it unless you say otherwise, so many people choose to condition their agent's health care authority on a written determination, by a doctor, a licensed psychologist, or a person they name, that they can no longer make their own decisions. Washington also runs a voluntary Health Care Declarations Registry where you can file this document, along with a living will or mental health directive, so providers can find it in an emergency.
Key Things to Know
- 1
Washington never wrote a stand-alone health care power of attorney statute. This document is the same kind of legal instrument as Washington's financial power of attorney, created under RCW Chapter 11.125's Uniform Power of Attorney Act, and it works by letting you, the principal, name a trusted adult, the agent, to make health care decisions for you if you become unable to make them yourself.
- 2
Health care authority is simply one type of power you can grant in that same kind of document.
- 3
Health care decision-making authority must be expressly granted in the document. It is not included automatically just because you sign a general power of attorney (RCW 11.125.240(1)(l), 11.125.400).
- 4
Unlike some states, Washington does not force your agent's health care authority to wait for an incapacity certification. The document is effective the moment you sign it unless you specifically state that it should only take effect once a doctor, licensed psychologist, or a person you name determines in writing that you cannot make your own decisions (RCW 11.125.090).
- 5
Unless your agent is your spouse, state registered domestic partner, parent, adult child, or sibling, your agent cannot be your physician, your physician's employee, or an owner, administrator, or employee of the facility where you live or receive care (RCW 11.125.400(3)).
- 6
You can sign before a notary public, or in front of two witnesses who are not your or your agent's home care or long-term care facility providers and are not related to you or your agent by blood, marriage, or state registered domestic partnership (RCW 11.125.050). You do not need both.
- 7
You can revoke the document at any time. Washington law does not prescribe a specific method, but you should tell your agent and providers, ideally in writing, since they are protected from acting on an outdated document until they actually know it has been revoked (RCW 11.125.100).
- 8
Washington runs a voluntary, statewide Health Care Declarations Registry where you can file this document along with a living will or mental health directive, so health care providers can find it in an emergency (RCW 70.122.130).
Key decisions before you file
Before you file a Healthcare Power of Attorney in Washington, a few decisions shape the document: which option to choose and what each one means. The Healthcare Power of Attorney guide walks through them.

Washington Requirements for Healthcare Power of Attorney
The principal designates a primary health care agent by expressly granting health care decision-making authority in the power of attorney document (RCW 11.125.240(1)(l)). Once granted, RCW 11.125.400 defines the scope of that authority.
The principal may name one or more successor agents who act if the primary agent resigns, dies, becomes incapacitated, is disqualified, or declines to serve. Unless the document states otherwise, successors hold identical authority and act only after all predecessors are unavailable (RCW 11.125.110(2)).
Once expressly granted under RCW 11.125.240(1)(l), the agent is authorized to provide informed consent for the principal's health care decisions and to act as the principal's HIPAA personal representative (RCW 11.125.400(1), (2)).
Federal HIPAA regulations govern how the agent can be authorized to access the principal's protected health information once the document is in effect.
A Washington power of attorney, including one granting health care authority, is effective immediately upon signing unless the principal states that it becomes effective only at a future date or upon a future event or contingency, such as incapacity (RCW 11.125.090(1)). Durable in Washington means the authority is not terminated by the principal's later incapacity (RCW 11.125.020), a different concept from when the authority first begins.
If the principal conditioned the agent's authority on incapacity, Washington determines incapacity by a written finding from a physician or licensed psychologist who has personally examined the principal and is unrelated to the principal by blood or marriage, or from a judge or other appropriate government official, using the chapter's incapacity definition, inability to manage affairs due to impaired ability to receive or evaluate information or communicate decisions, or absentee or out-of-country status (RCW 11.125.090(3), 11.125.020).
General authority over life-sustaining treatment, artificial nutrition and hydration, and palliative care flows from the agent's broad, expressly granted health care decision-making authority (RCW 11.125.240(1)(l), 11.125.400), not from RCW 11.125.420. RCW 11.125.420 is a hard statutory bar stating that no rights under Washington's Death with Dignity Act, aid-in-dying medication, chapter 70.245 RCW, may ever be exercised through a power of attorney, regardless of what the document says.
Under Washington's Uniform Anatomical Gift Act, an agent under a power of attorney for health care may make an anatomical gift on the principal's behalf during the principal's life, unless the power of attorney or another record prohibits it (RCW 68.64.030(2)).
RCW 11.125.400(2) expressly addresses mental health treatment decisions and cross-references directives under chapter 71.32 RCW, Washington's Mental Health Advance Directive Act. If a principal has appointed more than one agent with authority over mental health treatment decisions, the most recently appointed agent controls to the extent of any conflict, unless either appointment states otherwise.
A power of attorney terminates when the principal revokes it (RCW 11.125.100(1)(c)). Washington does not prescribe a specific method or form of notice for revocation, unlike some states. A third party who acts in good faith without actual knowledge of the revocation is protected (RCW 11.125.100(5)). If the agent is the principal's spouse or state registered domestic partner, the agent's authority, not the whole document, ends when a dissolution, annulment, or legal separation action is filed between them, unless the document states otherwise (RCW 11.125.100(2)(c)). This triggers on filing, not on a final decree.
The document may be signed in the presence of two or more competent witnesses instead of a notary. Both, or all, witnesses, not just one of two as in some states, must independently qualify. Neither may be a home care provider for the principal, nor a care provider at an adult family home or long-term care facility where the principal resides, and neither may be related to the principal or the agent by blood, marriage, or state registered domestic partnership (RCW 11.125.050(1)).
The principal may instead sign with the signature acknowledged before a notary public or other individual authorized by law to take acknowledgments. Notarization is a full alternative to witnessing, not an additional requirement on top of it, and no witnesses are needed if this option is chosen (RCW 11.125.050(1)).
Except as the power of attorney otherwise provides, a person accepts appointment as agent by exercising authority, performing duties as agent, or through any other conduct indicating acceptance. No separate signed acceptance form is statutorily required (RCW 11.125.130).
Unless the power of attorney otherwise provides, the agent is entitled to reimbursement of expenses reasonably incurred on the principal's behalf and to reasonable compensation (RCW 11.125.120).
The agent must act in accordance with the principal's reasonable expectations or best interest, act in good faith, and act only within the scope of granted authority. Absent a breach of duty, the agent is not liable solely because the principal's property declines in value, and is not liable for another agent's actions unless the agent participated in or concealed a known breach (RCW 11.125.140).
Washington does not have a general statutory procedure for resolving disagreements between agents and family members. What exists is narrower. If the principal names two or more coagents, they must exercise authority jointly unless the document says otherwise, and an agent who does not participate in or conceal another agent's known breach of duty is not liable for it (RCW 11.125.110). Separately, for mental health treatment decisions specifically, if more than one agent has that authority, the most recently appointed agent controls to the extent of any conflict, unless either appointment states otherwise (RCW 11.125.400(2)).
A power of attorney executed outside Washington is recognized if its execution complied with either the law of the jurisdiction that governs the power's meaning and effect, as stated in the document, per RCW 11.125.070, or with military power of attorney requirements under 10 U.S.C. Section 1044b (RCW 11.125.060(3)).
Washington's statutory Health Care Directive form, chapter 70.122 RCW, a separate document from this power of attorney, itself asks that, if the principal has also appointed a health care agent, the agent be guided by the directive's stated wishes and any other clear expressions of the principal's desires. This is guidance for the agent, not a strict legal-precedence or override rule between the two documents.
Frequently Asked Questions
A Durable Power of Attorney for Health Care in Washington is a legal document, created under the state's Uniform Power of Attorney Act, RCW Chapter 11.125, that lets you name a trusted adult, your agent, to make health care decisions for you if you are ever unable to make them yourself. It covers health care decisions such as consenting to or refusing treatment. Washington law requires this authority to be expressly stated in the document rather than assumed.
In Washington, both come from the exact same law, the Uniform Power of Attorney Act, RCW Chapter 11.125, and are signed the same way, either before a notary or in front of two qualifying witnesses. The difference is which powers you grant in the document. Financial powers such as banking, real estate, and business decisions are granted under RCW 11.125.240 through 11.125.390, while health care decision-making authority is a separate category under RCW 11.125.400 that must be expressly granted. You can combine both kinds of authority in one document or keep them separate. Washington law does not require two different instruments the way some states do.
Generally no. Washington law bars your physician, your physician's employees, and the owners, administrators, or employees of the health care or long-term care facility where you live or receive care from acting as your health care agent, unless that person is your spouse, state registered domestic partner, parent, adult child, or sibling (RCW 11.125.400(3)).
You need one or the other, not both. Washington law lets you sign before a notary public, or other person authorized to take acknowledgments, with no witnesses required, or sign in front of two competent witnesses instead. Those witnesses cannot be your or your agent's home care or long-term care facility providers, and cannot be related to you or your agent by blood, marriage, or state registered domestic partnership (RCW 11.125.050).
Yes. Washington operates a voluntary, statewide Health Care Declarations Registry, run by the Department of Health, where you can file this document along with a living will or mental health advance directive so providers can access it in an emergency (RCW 70.122.130). Filing is optional. Your document is legally valid whether or not you register it.
You can revoke it at any time. Washington law does not require a specific written form for revocation, but you should notify your agent and your health care providers, ideally in writing, because they are protected from relying on the document until they actually learn it has been revoked (RCW 11.125.100).
No. Washington law specifically states that no rights under the state's Death with Dignity Act, chapter 70.245 RCW, may be exercised through a power of attorney, no matter what the document says (RCW 11.125.420). This is a hard limit on what any health care agent can do in Washington, separate from the agent's general authority to consent to or refuse other medical treatment.
