Arizona Health Care Power of Attorney and Living Will

Arizona health care power of attorney guide for medical agents, living wills, mental health care powers, prehospital directives, POLST, and registry source checks.

By Settled Editorial

Arizona health care power of attorney questions usually start with one source path: who can speak for medical decisions, what the document says, how it relates to a living will, and whether registry steps need a fresh check before anyone relies on them.

Use this guide as source navigation, not legal, medical, or signing guidance. It is not legal advice. It does not choose an agent, decide capacity, tell a provider what to accept, approve a form, give registry filing instructions, or turn on Arizona estate-planning assessment or product support. Arizona remains disabled for public product and assessment use until a later approval gate.

Arizona Health Care Power Of Attorney At A Glance

The Arizona Attorney General's Life Care Planning page says Arizonans can make choices known about who will manage medical affairs in an emergency. The same page lists health care power of attorney, mental health care power of attorney, living will, prehospital medical directive, POLST, and registry materials.

A.R.S. 36-3221 is the starting statute for an Arizona health care power of attorney. It says an adult may designate another adult to make health care decisions on that person's behalf by executing a written health care power of attorney that meets the statute's listed requirements.

Keep the document families separate:

TopicSource path
Who can speak for medical decisions?Arizona health care power of attorney source path.
What treatment preferences are written down?Living will source path.
What mental health treatment decisions need separate planning?Mental health care power of attorney source path.
What happens in cardiac or respiratory arrest before hospital care?Prehospital medical care directive source path.
What medical orders follow a seriously ill or frail patient?POLST source path.
Where can advance directives be registered?Arizona Secretary of State and AzHDR source path.

This page keeps those source paths in one place so families do not confuse a medical decision document with a financial POA, probate authority, or a post-death court role. Use the Arizona estate planning basics guide for the wider will, trust, beneficiary, financial POA, and medical-directive planning sequence. Use the Arizona guardianship planning guide when medical decision documents intersect with adult guardianship, minor-child planning, court authority, or alternatives to guardianship.

Health Care Power Of Attorney Source Checks

An Arizona health care power of attorney is a lifetime document. It can name a medical agent for health care decisions, and the statute also references funeral and disposition arrangements in the event of death. That does not mean the document answers every after-death question. Probate, title, estate assets, and court authority use a different source path.

A.R.S. 36-3221 gives these source checks:

  • the person is an adult
  • the document clearly indicates intent to create a health care power of attorney
  • the document is dated and signed or marked, unless the statute's physical-inability rule applies
  • the document is notarized or witnessed in writing by at least one adult under the statute's framework
  • the notary or witness confirms presence and that the person appeared to be of sound mind and free from duress at execution
  • certain people cannot act as notary or witness for this document

Treat those as statute review points, not step-by-step signing advice. A real document can raise questions about identity, current form version, witness fit, notary process, capacity facts, medical provider acceptance, older directives, or conflict between family members. If any of those facts matter, ask counsel or the care provider before relying on the document.

What A Health Care Agent Can Do

A.R.S. 36-3223 addresses agent powers and duties. The statute says a health care agent may make and communicate health care decisions while the principal is unable to do so. It also says the agent's authority is limited by express language in the document or by court order.

That source point matters because the document, not only the statute label, controls the question. Before anyone says what an agent can do, gather:

  • the signed health care power of attorney
  • any living will attached to it or kept with it
  • any mental health care power of attorney
  • any newer document or revocation source
  • any court order, guardianship, or disputed authority record
  • the provider's document-review process

This guide does not decide whether a person is unable to make decisions, whether an agent can consent to a treatment, or whether a hospital, clinic, hospice, emergency responder, registry, or court accepts a document.

Revocation Source Path

The Attorney General's Life Care Planning page points readers to A.R.S. 36-3202 for health care POA revocation source review. Use that statute as a source path when a person asks how a prior health care document may be revoked or replaced.

Do not rely on a revocation answer without checking where the older document went. A prior directive may have been shared with an agent, family member, physician, hospital, hospice, registry, or care facility. If the document was registered, registry update steps may be separate from the document itself.

Practical source questions include:

  • Which document is the newest?
  • Was any written revocation signed?
  • Who received a copy of the prior document?
  • Does the health care provider have the current version?
  • Does AzHDR need a new submission or update?
  • Is a family dispute or capacity concern present?

This guide cannot tell a reader that a revocation reached every recipient. Use the statute, the provider's process, registry instructions, and counsel when the answer affects care.

Living Will And Treatment Preferences

A.R.S. 36-3261 says an adult may prepare a written statement known as a living will to control health care treatment decisions that can be made on that person's behalf. The statute says the living will may be used as part of or instead of a health care power of attorney or to disqualify a surrogate.

A.R.S. 36-3262 offers a sample living will form and says any writing that meets the article's requirements may be used to create a living will. It also says a person may write and use a living will without writing a health care power of attorney or may attach a living will to the health care power of attorney.

The living will source path answers a different question from the agent source path. A health care power of attorney asks who can speak. A living will records treatment preferences. Many families need both questions in the same folder, but the documents do different jobs.

Use caution with treatment-preference copy. This guide does not tell someone which choices to initial, whether to refuse or request a treatment, or how a provider will apply a directive. Ask a physician, care team, or counsel about medical wording and personal facts.

Mental Health Care Power Of Attorney

Arizona has a separate mental health care power of attorney source path. A.R.S. 36-3281 says an adult principal may designate another adult or adults to make mental health care decisions on the principal's behalf. It also lets the principal designate alternates if the first agent is unwilling or unable to act.

The same statute says an agent may make decisions about mental health treatment if the principal is found incapable. It also says a health care power of attorney agent may make mental health treatment decisions if an adult does not have a mental health care power of attorney, except as provided in the mental health care statute.

Those source points do not answer every mental health planning question. A reader may need medical input, counsel, and current form review if the document touches inpatient treatment, medication, crisis care, facility rules, family conflict, or prior directives.

Do not blend the documents in a way that hides the issue. If mental health decisions matter, review the mental health care power of attorney source and the Attorney General form materials directly.

Prehospital Directive And POLST

Arizona's prehospital medical care directive source path is separate from the standard Arizona health care power of attorney. A.R.S. 36-3251 addresses a prehospital medical care directive for cardiac or respiratory arrest and states that the authorization for withholding CPR does not include withholding other medical interventions, such as fluids, oxygen, or therapies considered necessary for comfort care or pain relief.

The Attorney General's Life Care Planning page links prehospital medical directive forms and notes orange-background requirements. Read the current form and statute before relying on any copy or print instruction. This guide does not give emergency-response instructions or say a form will be honored in a specific event.

POLST is also separate. The Attorney General page links a POLST form and says the form is for when a person becomes seriously ill or frail and toward the end of life. Treat POLST as a medical-order source path to review with a clinician, not as a substitute for a living will or health care power of attorney.

Ask the care team before using POLST language in a plan. The source path can help identify the form family, but the medical decision belongs with the patient, clinician, agent, and legally appropriate review.

Arizona Healthcare Directives Registry

Arizona registry source checks need current review. The Arizona Secretary of State Advance Directives page says the Secretary of State's Office no longer processes advance directive documents as of September 24, 2021, and that the registry moved to AzHDR, Arizona's Health Information Exchange. The page says documents received after that date are forwarded to AzHDR, which communicates with applicants about how to proceed.

AzHDR's registration page gives current consumer-facing registry steps. It says the registration agreement needs to be included with advance directives, copies rather than originals are sent, walk-in drop-off is not accepted, and confirmation comes from Contexture when documents are available for viewing in the registry.

Use this registry section as source navigation only. Registry submission does not, by itself, prove a health care power of attorney is valid, current, accepted by a provider, or right for a person's facts. Before publication or product use, Settled needs a same-day recheck of the Secretary of State page, AzHDR instructions, registration agreement, and FAQs.

Financial POA Versus Health Care Directive

Do not use a medical document to answer financial authority questions. The Arizona power of attorney guide covers durable financial authority, agent roles, incapacity source checks, revocation, and financial POA risk. This page covers medical-agent and advance-directive source paths.

Use this split:

QuestionBetter starting page
Who can handle bank, property, tax, or benefit tasks while I am alive?Arizona financial power of attorney.
Who can speak for health care if I cannot?Arizona health care power of attorney.
What treatment preferences do I want documented?Living will.
What happens after death to assets or court authority?Arizona probate source path.

If a death has already happened, a health care directive usually stops being the main document. The family may need death certificates, title records, court forms, small-estate source checks, or probate authority. Use the Arizona probate guide for after-death source navigation.

Arizona Health Care Power Of Attorney Checklist

Before relying on an Arizona health care power of attorney answer, gather the source material first:

  1. Current health care power of attorney document.
  2. Any living will attached to it or stored with it.
  3. Any mental health care power of attorney.
  4. Any prehospital medical care directive or POLST.
  5. Any newer directive or revocation source.
  6. Names and contacts for the agent and alternate agents.
  7. Health care provider document-review instructions.
  8. AzHDR registry status and current registry instructions, if registration matters.
  9. Counsel or care-team guidance when there is conflict, capacity concern, urgent care, serious illness, mental health treatment, or unclear document language.

Next steps. Keep a copy of each source reviewed with the directive folder. If a source does not answer the facts, pause before filling the gap with assumptions.
