If illness or an accident ever leaves you unable to speak for yourself, someone will make your medical decisions. The only question is whether you chose that person, or whether a hospital and a statute chose for you. Arizona's health care power of attorney settles it in one signed page, and it is one of the simplest documents in all of estate planning.
What it does
You name an adult you trust - your agent - to make health care decisions on your behalf when you cannot. You can name backups in case your first choice is unavailable. The same document may also authorize the agent to handle funeral and disposition arrangements, which spares your family a second set of decisions on their hardest day.
Arizona's signing rules
- You must be an adult, and the document must clearly say it is a health care power of attorney.
- It must be dated and signed by you.
- It must be notarized OR witnessed by at least one qualifying adult. One qualifying witness or a notary - Arizona keeps this deliberately simple.
- If you are physically unable to sign, the statute allows you to direct the signing in front of the notary or witness.
Choosing the right agent
Pick the person who will actually follow your wishes under pressure, not the person who would be hurt to be passed over. Tell them what you want while everyone is healthy - the document gives them authority, but the conversation gives them peace. Many couples name each other first, then an adult child as backup.
Pair it with a living will
The living will (A.R.S. § 36-3261) is your written statement about end-of-life treatment. It can stand alone or be part of a health care power of attorney; verified the same way as a health care POA. Signed together, the two documents mean your agent never has to guess, and never has to carry a decision alone that you could have made for them.
The free official forms
The Arizona Attorney General publishes free statutory health care directive forms, including the health care power of attorney and living will. They are a legitimate way to get this document in place. What the free forms cannot do is coordinate the rest: the financial power of attorney with its stricter signing rules, and the will or trust that takes over after. That is a fifteen-minute conversation.
