A medical emergency can happen without warning. If you cannot speak for yourself, whether due to surgery, an accident, or incapacitation, who makes decisions about your treatment?
Without a durable power of attorney for health care (HCPOA), Arizona law does not automatically grant that authority to your spouse or adult children. A court may need to intervene, causing delays that directly affect your care. This document prevents that outcome.
What Is a Durable Power of Attorney for Health Care?
A durable power of attorney for health care is a legal document that designates a specific person called your health care agent or proxy to make medical decisions on your behalf when you lack the capacity to do so yourself.
The term “durable” means the document remains effective even if you become mentally incapacitated. A standard (non-durable) power of attorney would terminate upon incapacity, which is precisely when it is needed most.
Your health care agent can make decisions about:
- Consent to or refusal of specific treatments or procedures
- Choice of physicians, hospitals, and care facilities
- Access to your medical records (often combined with a HIPAA authorization)
- Organ donation and anatomical gifts
- End-of-life care decisions, within the bounds of your stated wishes
How Is This Different From a Living Will?
| Feature | Health Care POA | Living Will |
|---|---|---|
| Who acts | Appoints a person to make decisions | No agent; documents your wishes |
| When active | When you lack decision capacity | Terminal condition or permanent unconsciousness |
| Scope | Broad medical decisions | Specific end-of-life treatment preferences |
| Flexibility | Agent adapts to changing circumstances | Fixed instructions for specific scenarios |
| Works best when | You want someone to advocate for you | You want to pre-specify exact instructions |
In Arizona, most estate plans include both documents. The HCPOA appoints your agent; the living will records your specific wishes on life-sustaining treatment. Together, they give both your agent and your medical team clear guidance.
Arizona Legal Requirements for a Valid HCPOA
Under Arizona Revised Statutes §36-3221, a health care power of attorney must meet specific requirements to be legally enforceable:
- Must be in writing
- Must be signed and dated by the principal (the person granting authority)
- Must be signed before two adult witnesses OR notarized
- Witnesses cannot be the health care agent, a health care provider, or an employee of a health care facility where you receive treatment
- The agent must be an adult (18 or older)
An improperly executed HCPOA may be rejected by a hospital or treating physician at the moment it is needed most. Working with an Arizona estate planning attorney ensures your document meets all statutory requirements.
Choosing Your Health Care Agent
This is the most important decision in the entire document. Your agent will speak for you when you cannot. Choose someone who:
- Understands your values and wishes, not just what they would choose for themselves
- Can remain calm and assertive under pressure from medical professionals or family members
- Lives nearby or can travel quickly if needed
- Is willing to have honest conversations with you now, before a crisis
Many people choose a spouse. But in blended families, aging parents, or situations involving competing family interests, a sibling, trusted friend, or adult child may be a better choice. Name an alternate agent in case your first choice is unavailable.
What Happens Without a Health Care POA in Arizona?
Without a valid HCPOA, Arizona follows a surrogate decision-making hierarchy under A.R.S. §36-3231. Medical providers will look to the following people, in order:
- Court-appointed guardian (if one exists)
- Spouse (unless legally separated)
- Adult child (majority vote if more than one)
- Parent
- Adult sibling
- Close friend
This process creates delays, family conflict, and decisions made by people who may not know your wishes. For blended families especially, a surviving spouse may make decisions that biological children disagree with, and without a formal document, neither party has clear legal authority.
HCPOA and HIPAA: What You Also Need
A HIPAA authorization allows your designated agent to access your medical records. Without it, providers may refuse to share information with your agent, limiting their ability to make informed decisions. Citadel Law Firm includes HIPAA authorization as part of every health care power of attorney package we prepare.
When Should You Create a Health Care POA?
The answer is: before you need it. Most people think of this document only after a health crisis when it may be too late to execute one properly. If a person lacks mental capacity, they cannot sign legal documents.
Key life events that should trigger review include:
- Turning 18 (college students should have one before leaving home)
- Marriage or divorce
- Serious illness diagnosis
- Upcoming surgery or medical procedure
- Aging parent who has not yet executed one
The Role of an Attorney in Preparing Your HCPOA
Online forms exist, but they carry real risk. A generic HCPOA may omit language specific to Arizona law, fail to address your family’s dynamics, or lack the specific instructions that prevent disputes. An attorney at Citadel Law Firm reviews your full situation before drafting a document tailored to you.

5 Frequently Asked Questions
Does a health care POA expire in Arizona?
No. A properly executed HCPOA remains valid indefinitely unless you revoke it. However, reviewing it every few years or after major life changes is strongly recommended.
Can my health care agent override my doctor’s recommendation?
Your agent can consent to or refuse any treatment on your behalf. However, they must act in your best interest and consistent with your known wishes, not their own preferences.
What if I want different people to handle finances and health decisions?
You can and often should appoint different agents. A financial power of attorney handles money; an HCPOA handles medical. Many Arizona estate plans name separate agents for each role.
Can a hospital refuse to honor my HCPOA?
A facility may decline for conscience reasons but must inform your agent and assist in transferring care. A properly executed document is difficult to challenge and should be honored in most cases.
Is a verbal agreement with a family member enough?
No. Verbal agreements have no legal standing in Arizona. Medical providers require a signed, witnessed or notarized document. Without one, your family member has no formal authority.
