When you cannot speak for yourself, someone else will make health care choices for you. In Arizona, who that person is depends on whether you planned ahead. The right papers put you in control. Without them, a court may decide for you.
If You Have a Health Care Power of Attorney
A health care power of attorney is the strongest tool for naming a medical decision maker. Under A.R.S. 36-3221, any adult can pick another adult to make health care choices for them. Your named agent can approve or refuse treatments. They can choose doctors and care centers. They can make choices about long-term care. The agent steps in only when you are unable to make or share choices yourself.
The paper must be in writing, dated, signed, and either notarized or witnessed. Arizona law limits who can serve as a witness. The witness cannot be your named agent or someone involved in your care at the time you sign. If you use a single witness instead of a notary, that witness cannot be a relative or someone who would inherit from your estate.
If You Have a Living Will
A living will does not name a decision maker. Instead, it gives written instructions about the care you want or do not want at the end of life. If you are terminally ill, in a lasting vegetative state, or in a coma that cannot be reversed, your directive tells the medical team what to do.
Under A.R.S. 36-3209, if your directive conflicts with a doctor's order, your directive is presumed to represent your wishes. If you signed more than one directive over the years, the most recent version controls.
If You Have No Documents: Surrogate Decision Makers
When there is no health care power of attorney and no directive, Arizona law has a backup. Under A.R.S. 36-3231, a surrogate can step in to make health care choices for you. The law sets a priority list:
- Your spouse (unless legally separated)
- An adult child
- A parent
- A domestic partner
- A brother or sister
- A close friend who knows your values and health care wishes
If more than one person at the same level disagrees, the doctor usually follows the majority. If there is no majority, the doctor follows the person they believe best knows your wishes.
Why the Surrogate System Is Not Enough
The surrogate list sounds fair. But it creates real problems. Family members may disagree about what you would want. A brother or sister may see things differently than your adult child. And if no one on the list is around or willing to serve, the hospital may need to go to court.
A court-appointed guardian can make medical choices for you. But the process is slow, costly, and public. It also puts a stranger, the judge, in charge of picking who speaks for you. That is not what most people want.
Documents That Work Together
The best approach uses three papers together:
- Health care power of attorney to name your decision maker
- Living will to state your care wishes
- HIPAA authorization to give your agent access to your medical records
These papers make sure the right person can act fast when you are unable to make health care choices on their behalf. They remove guesswork. They prevent family fights. They keep the courts out of your medical care.
Having these papers in place is one of the most important steps anyone can take. It costs far less than a guardianship case. And it gives you peace of mind that your wishes will be followed. That is the smart play.
