No. In Arizona, a durable financial power of attorney does not authorize your agent to make health care decisions. The financial power of attorney under A.R.S. § 14-5501 covers financial and legal decisions only — the statute says nothing about medical care. To let someone make health care decisions for you, Arizona requires a separate document: a health care power of attorney under A.R.S. § 36-3221. Most people need both, and many need a third for mental health care.
Why one document isn’t enough
Arizona splits incapacity planning across separate statutes, and each instrument does one job:
- Durable (financial) power of attorney — § 14-5501. Your agent handles money: bank accounts, bills, real estate, taxes, investments, insurance. “Durable” means the authority survives your incapacity.
- Health care power of attorney — § 36-3221. Your agent makes medical treatment decisions and, if you authorize it, funeral and disposition arrangements.
- Mental health care power of attorney — § 36-3281. A distinct Arizona document for mental health treatment decisions.
- Living will — § 36-3251. Not an appointment of anyone; it records your own end-of-life wishes for your agent and doctors to follow.
A financial power of attorney can be extremely broad and still leave a hospital unable to take direction from your agent, because the authority simply isn’t there. Naming the same person in each is common and usually sensible — but it takes separate signatures on separate documents.
The signing requirements are different too
This trips people up, and getting it wrong can invalidate the document:
- Financial durable POA (§ 14-5501) requires both a witness and a notary. The witness cannot be the agent, the agent’s spouse, the agent’s children, or the notary public.
- Health care POA (§ 36-3221) requires notarization or at least one adult witness — not both. The notary or witness cannot be your named agent or anyone directly involved in providing your health care when you sign. With only one witness, that witness cannot be related to you by blood, marriage, or adoption, or be entitled to any part of your estate.
So a health care power of attorney signed in front of two of your children may be perfectly valid, while a financial power of attorney signed the same way is not.
What happens if you never sign one
You don’t end up with nobody — you end up with whoever the Arizona statute says has priority to speak for you as your surrogate. Under A.R.S. § 36-3231, if you can’t make or communicate your own treatment decisions and have no health care power of attorney, providers turn to a surrogate list in priority order: your spouse (unless legally separated), then an adult child, then a parent, then a domestic partner, then a sibling, then a close friend. A court-appointed guardian with health care authority takes precedence.
Two problems with that. It may not be the person you’d have chosen — and with several adult children, the statute doesn’t break the tie. And a surrogate must act on your known wishes; if nobody knows what those were, they act on their best guess at your best interest. The alternative to a signed health care power of attorney isn’t freedom — it’s a court case, or a decision made by default.
Mental health care is a third, separate document
Arizona is unusual here, and it matters. A standard health care power of attorney does not necessarily let your agent admit you to an inpatient psychiatric facility. Arizona recognizes a separate mental health care power of attorney (A.R.S. § 36-3281 and following), and the authority to seek inpatient evaluation or treatment must be specifically granted — the statutory sample form uses a separate line to initial. Without it, your agent can hold a valid power of attorney in every other respect and still be unable to consent to inpatient care.
Related questions
Doesn’t a durable power of attorney cover medical decisions in other states?
Some states use a single combined instrument, which is where much of the confusion comes from — national forms and online advice often assume it. Arizona doesn’t work that way. Whatever a form is called, in Arizona you want a document satisfying § 36-3221 for health care and a separate one satisfying § 14-5501 for finances.
Can my agent see my medical records under a financial power of attorney?
Not reliably. Access to protected health information is governed by HIPAA, and providers generally look for a health care power of attorney or a specific HIPAA authorization. Many Arizona estate plans include a stand-alone HIPAA release precisely so a family member can get information even when no treatment decision is on the table.
When does each one take effect?
A durable financial power of attorney can be effective immediately on signing, or drafted to spring into effect only on incapacity, depending on how it’s written. A health care power of attorney operates when you’re unable to make or communicate your own health care decisions — while you have capacity, you decide for yourself, regardless of what any document says.
