Arizona Healthcare Power of Attorney Requirements
Arizona asks for less at the signing table than many states do: a single adult witness is enough to make a Health Care Power of Attorney valid, or a notary's acknowledgment alone, with no need to combine the two or round up a second witness.
Introduction
Arizona asks for less at the signing table than many states do: a single adult witness is enough to make a Health Care Power of Attorney valid, or a notary's acknowledgment alone, with no need to combine the two or round up a second witness. That signed document lets you name someone you trust, called an agent, to make health care decisions for you if you are ever unable to make them yourself. Arizona creates and governs this document under Title 36, Chapter 32, Article 2 of the Arizona Revised Statutes (Sections 36-3221 through 36-3224), and its authority also extends, if you choose, to funeral and disposition arrangements after your death. This is not a general or financial power of attorney; its authority reaches only health care decisions, and it works differently than people often assume. Your agent cannot make decisions the moment you sign. Your agent's authority begins only once you are unable to make or communicate health care decisions yourself, and it ends automatically if you recover the ability to decide. Arizona gives you two ways to make the document legally valid: sign it before at least one qualified witness, or sign it before a notary public. There is no fixed form you must use, only a sample the statute offers, and Arizona also runs a free Health Care Directives Registry, currently operated by Contexture, where you can optionally store a copy so health care providers can find it in an emergency.
Key Things to Know
- 1
Unlike several other states, Arizona does not disqualify your own treating physician from serving as your health care agent. The Health Care Power of Attorney itself simply lets you, the principal, name any trusted adult, including your doctor if you choose, to make health care decisions for you once you become unable to make them yourself.
- 2
Your agent's authority does not start the moment you sign. It begins only once you are unable to make or communicate your own health care decisions (A.R.S. Section 36-3223(A)).
- 3
Unless you limit it in the document, your agent may make any health care decision for you, and you can also give your agent authority over funeral and burial disposition after your death.
- 4
If you have not signed a separate Mental Health Care Power of Attorney, your agent automatically gets authority over ordinary mental health treatment decisions too, but your agent needs your express written permission in this document before consenting to your admission to an inpatient psychiatric facility (A.R.S. Sections 36-3281(B), 36-3283(F)).
- 5
You need only one witness, or a notary instead. Arizona does not require two witnesses like some states. Any witness cannot be your agent or someone directly involved in providing your care; if you use only one witness, that person also cannot be related to you by blood, marriage, or adoption, and cannot be entitled to any part of your estate.
- 6
Arizona law does not bar your own doctor from serving as your agent. It only bars a person directly involved in providing your care from serving as your witness, so review who you name as agent carefully even though the statute allows it.
- 7
You can revoke the document at any time by a written revocation, an oral statement to your agent or a health care provider, signing a new health care directive, or any other act that shows you intend to revoke it. No specific form is required.
- 8
Arizona operates a free Health Care Directives Registry where you can store a copy of your signed document so providers can find it in an emergency, but registering is optional. Your document is legally valid whether or not you register it.
- 9
This is a different document from Arizona's Durable Power of Attorney, which covers property and financial decisions, not health care.

Arizona Requirements for Healthcare Power of Attorney
The document must comply with Arizona's health care power of attorney statutes, Title 36, Chapter 32, Article 2 (A.R.S. Sections 36-3221 through 36-3224), which set the execution, agent authority, and sample form rules for this instrument.
A.R.S. Section 36-3221(A) lets an adult principal designate one or more adult agents to make health care decisions, and, under the same subsection, to handle funeral and disposition arrangements after death. The sample form at A.R.S. § 36-3224 provides for naming a successor agent.
Section 36-3223(A) makes the named agent entitled to make and communicate health care decisions for the principal once the principal is unable to do so, and Section 36-3223(B) states the agent's authority is limited only by the express language of the document itself or by court order. The agent's authority is broad and not limited to a specific list of powers, unless the principal adds express limitations in the document.
If the principal has not signed a separate mental health care power of attorney, the agent named under this health care power of attorney automatically has authority to make mental health treatment decisions once the principal is found incapable (Section 36-3281(B)). One mental health decision needs express written authorization in the document itself regardless: consenting to the principal's admission to a licensed inpatient psychiatric facility (Section 36-3283(F)). Absent that express statement, the agent may not consent to that specific admission.
Under Section 36-3223(A), the agent may act only while the principal is unable to make or communicate health care decisions, but Arizona's health care power of attorney statute does not itself define a certification procedure, such as a written physician certification filed in a medical record, for reaching that determination. Arizona's separate mental health care power of attorney statute does define a specific certification process (opinion of a specialist physician or licensed psychologist, Section 36-3281(D)), but that process does not carry over to this general document.
The principal signs and dates the document, or, if physically unable, directs someone else to sign and has that fact verified on the document. The signature is either notarized or witnessed in writing by at least one adult (Section 36-3221(A), (B)). That notary or witness may not be the named agent, and may not be a person directly involved in providing the principal's health care at the time of signing (Section 36-3221(C)). If only one witness signs, that witness additionally may not be related to the principal by blood, marriage, or adoption, and may not be entitled to any part of the principal's estate (Section 36-3221(D)).
Federal HIPAA regulations govern how the agent can be authorized to access the principal's protected health information once the document is in effect.
The principal may revoke a health care power of attorney by making a written revocation, orally notifying the agent or a health care provider, executing a new health care directive, or any other act demonstrating specific intent to revoke (Section 36-3202).
Section 36-3262 confirms a principal may attach a living will to a health care power of attorney, and that if a principal has a health care power of attorney, the agent must make health care decisions consistent with the principal's known desires. The sample health care power of attorney form itself (Section 36-3224) includes a checkbox confirming whether a living will is attached.
Under Arizona's Revised Uniform Anatomical Gift Act, an agent under a health care power of attorney may make an anatomical gift on the principal's behalf during the principal's lifetime, unless the health care power of attorney or another record signed by the principal prohibits it (Section 36-843(2); agent defined at Section 36-841(2)(a)).
A surrogate, including an agent acting under a health care power of attorney, who makes good faith health care decisions for the principal is not subject to civil or criminal liability for those decisions, and decisions made in reliance on the health care directive are presumed to be made in good faith (Section 36-3203(D)).
Facilities that participate in Medicare and Medicaid must inform patients of their rights under state law to make advance directives, including a Health Care Power of Attorney.
Arizona has its own specific out-of-state recognition rule for health care directives: a health care directive prepared in another state, district, or territory of the United States is valid in Arizona if it was valid where and when it was made, so long as it does not conflict with Arizona's criminal laws (Section 36-3208).
The statutory sample health care power of attorney form lets a principal name a successor agent who serves if the primary agent is unwilling or unable to serve or continue to serve (Section 36-3224).
The agent's authority to make health care decisions becomes exercisable only while the principal is unable to make or communicate those decisions, and lasts until the principal revokes the appointment or a court order ends it (Section 36-3223(A), (C); and the document is durable by definition (Section 36-3201(6))). Arizona's statute does not specify a fixed expiration date or a required renewal interval. The document remains in effect until revoked.
Frequently Asked Questions
A Health Care Power of Attorney in Arizona is a legal document, created under Arizona Revised Statutes Title 36, Chapter 32, Article 2, that lets you name a trusted adult (your agent) to make health care decisions for you if you ever become unable to make them yourself. It covers only health care decisions, and optionally funeral and disposition arrangements, and your agent's authority begins only once you are unable to make or communicate your own decisions.
A Health Care Power of Attorney covers only health care decisions. Arizona's Durable Power of Attorney (A.R.S. Section 14-5501) covers financial matters instead, such as banking or property, and requires you to choose at signing whether it takes effect immediately or only springs into effect on your incapacity. The Health Care Power of Attorney has no such choice, since Arizona law makes it effective only while you are unable to make or communicate health care decisions yourself, and there is no immediate-effect option. Execution differs too. The Durable Power of Attorney requires both a disinterested witness and notarization, while the Health Care Power of Attorney only needs one witness or a notary, not both.
Only one, unless you choose notarization instead, in which case no witness is needed at all (A.R.S. Section 36-3221). Any witness cannot be your named agent or someone directly involved in providing your health care at the time you sign; if you use only one witness, that person also cannot be related to you by blood, marriage, or adoption, and cannot be entitled to any part of your estate.
Arizona law does not prohibit it. Unlike some states, Arizona's Health Care Power of Attorney statute bars a person directly involved in providing your health care only from serving as your witness, not from serving as your agent (A.R.S. Section 36-3221(C)). If you want to avoid a potential conflict of interest, choose someone other than your treating provider anyway, since the law simply does not require it.
Yes. Arizona operates a free Health Care Directives Registry, currently run by Contexture under a designation from the Department of Health Services (A.R.S. Sections 36-3291 through 36-3296). Registering is optional. Your document remains legally valid whether or not you register it, and failing to notify the registry of a revocation does not affect the revocation's validity.
You can revoke it at any time by making a written revocation, telling your agent or a health care provider orally, signing a new health care directive, or through any other act that shows you intend to revoke it (A.R.S. Section 36-3202). No specific form is required.
Arizona law allows another adult to sign on your behalf, as long as you directly indicate to the notary or witness that the document expresses your wishes and that you intend to adopt it. The notary or witness must verify this on the document itself (A.R.S. Section 36-3221(B)).
