Arizona Living Will: Directing Your Own End-of-Life Care
A living will is how you keep control of your medical care even when you can no longer speak for yourself. It’s a written statement of what treatment you do and don’t want if you’re ever incapacitated by a terminal condition, an irreversible coma, or a persistent vegetative state — decisions about resuscitation, mechanical ventilation, tube feeding, and other life-sustaining measures. In Arizona, a living will is one of the most important — and most misunderstood — pieces of an estate plan. It’s not a last will and testament (that deals with property after death), and it works best hand-in-hand with a healthcare power of attorney. This guide explains what an Arizona living will does, how to make one valid, and how it fits with your other documents. Available 24/7 • Free confidential consultations • (480) 725-2257
What a living will is (and isn’t)
A living will (governed by A.R.S. § 36-3261) is a written statement directing your future health care — specifically the life-sustaining treatment decisions that come up at the end of life. It lets you say, in advance, what you’d want in situations where you can’t communicate.
A living will is NOT a last will and testament. This is the single most common point of confusion. A last will distributes your property after you die. A living will directs your medical care while you’re alive but incapacitated. They share a word and nothing else. Everyone needs a last will; a living will is optional but strongly recommended. Don’t confuse the two when planning.
A living will typically addresses decisions like:
- Resuscitation (CPR) — whether and when you’d want your heart restarted if it stops
- Mechanical ventilation — whether, and for how long, you’d want a machine to breathe for you
- Artificial nutrition and hydration (tube feeding) — whether you’d want to be fed through a tube
- Other life-sustaining or comfort care — dialysis, antibiotics, pain management, and similar measures
When a living will takes effect
A living will doesn’t control your care while you can still make decisions — it sits inactive in your medical file until two things are both true: a physician determines you can no longer make or communicate your own health care decisions, and you have a qualifying medical condition (typically a terminal illness, irreversible coma, or persistent vegetative state). Until both conditions are met, you remain in charge of your own care. Once they are, your living will guides your treatment.
Making an Arizona living will valid
Arizona sets specific execution requirements. A standalone living will must be verified the same way as a healthcare power of attorney under A.R.S. § 36-3221. In practice, that means the document must be:
- In writing
- Dated
- Signed (or marked) by you, the principal
- Either notarized OR witnessed by at least one adult — not both
Notary OR one witness — you only need one. A frequent mistake is thinking you need both a notary and a witness. Arizona requires one or the other. If you use a single witness, that witness cannot be the agent you named, a person directly providing your health care, and — because it’s a sole witness — cannot be someone related to you by blood, marriage, or adoption, or someone who stands to inherit from you. The witness or notary must affirm you appeared to be of sound mind and free from duress when you signed.
Arizona’s Attorney General publishes a free Life Care Planning packet with a living will template, and you can register your completed directive with the Arizona Health Care Directives Registry (AzHDR), a free state service that stores it electronically so your medical team can find it. Registration is optional and doesn’t affect the document’s validity.
The living will’s important limitation — and why you also want a healthcare POA
A living will has a real limit worth understanding. It speaks for you, but it can’t anticipate every situation, and Arizona’s Attorney General has noted it’s narrower than a healthcare power of attorney. For example, a living will alone generally does not permit a provider to stop tube feeding — only an agent under a healthcare power of attorney (or a court-appointed guardian) can make that kind of decision.
That’s why the two documents work best together: the healthcare power of attorney names a trusted person (an agent) to make real-time decisions across any medical situation, and the living will gives that agent — and your doctors — clear written guidance about your end-of-life wishes. Arizona’s AG recommends attaching your living will to your healthcare power of attorney. Together they cover both “who decides” and “what I want.”

A living will is one piece of a complete Arizona plan. The core health-and-incapacity documents work together:
| Document | What it does |
|---|---|
| Living will | States your end-of-life treatment wishes (this page) |
| Healthcare power of attorney | Names an agent to make medical decisions for you |
| Mental health care power of attorney | Names an agent for mental health decisions specifically |
| Financial power of attorney | Names an agent to handle finances if you’re incapacitated |
| Last will / living trust | Directs your property after death |
Most Arizona adults benefit from having all of these in place. See our Arizona estate planning overview for how the full plan fits together.
Frequently asked questions
Do I need a lawyer to make a living will in Arizona?
No — Arizona doesn’t require an attorney, and the Attorney General’s office provides a free form. But an estate planning attorney helps ensure the document is valid, reflects your actual wishes, and coordinates properly with your healthcare power of attorney and the rest of your plan. Generic forms sometimes miss coordination issues that matter later.
Does an Arizona living will need to be notarized?
It needs to be either notarized OR signed by one qualifying witness — not both. One or the other satisfies Arizona’s requirement.
What’s the difference between a living will and a healthcare power of attorney?
A living will states your treatment wishes; a healthcare power of attorney names a person (agent) to make decisions for you. The living will is guidance; the healthcare POA is a decision-maker. They complement each other, and Arizona’s AG recommends using both together — a living will alone can’t authorize some decisions (like stopping tube feeding) that an agent under a healthcare POA can.
Can I change or revoke my living will?
Yes. As long as you’re able to make decisions, you can update or revoke your living will at any time. It’s wise to review it periodically and after major life or health changes.
Will Arizona doctors follow my living will?
Arizona law requires providers to follow a valid living will, and it protects providers who follow one in good faith from liability. If family members disagree with the directive, they can petition the superior court, which evaluates whether the document reflects your actual intent — another reason to make sure it’s properly drafted.
What happens if I don’t have a living will?
Without one, Arizona law lets a surrogate decision-maker be chosen from a statutory priority list (A.R.S. § 36-3231) — typically a spouse, adult child, or other relative. That means someone else decides, possibly not knowing your wishes, and possibly not the person you’d have chosen. A living will plus a healthcare POA puts you back in control.
