Most people assume that if something serious happened to them, their family would know what to do. That their spouse, their kids, or their closest friend would step in and make the right calls. And maybe they would—but without the right legal documents in place, it might not matter what they want. Hospitals and doctors can't take a family member's word for it. They need paperwork.
That's what advanced directives are. They're the legal documents that tell medical providers exactly what you want—and who's allowed to speak for you—if you can't speak for yourself. Setting them up isn't morbid. It's one of the most considerate things you can do for the people who love you.
Here's everything you need to know.
What Are Advanced Directives?
"Advanced directive" is an umbrella term for a set of legal documents that spell out your healthcare wishes in advance—before a crisis happens. There are two main ones you need to know about:
- A Living Will—a document that tells doctors what kind of medical treatment you do or don't want if you're incapacitated
- A Healthcare Power of Attorney (Healthcare Surrogate)—a document that names a specific person to make medical decisions on your behalf
Most people need both. They serve different purposes and work together.
Living Wills: Putting Your Wishes in Writing
A living will—sometimes called a healthcare directive or directive to physicians—is your chance to spell out your medical preferences before you're ever in a position where you can't communicate them yourself.
It typically covers situations like:
- Terminal illness — If you're diagnosed with a condition that will result in death and there's no reasonable chance of recovery, do you want life-sustaining treatment continued, or would you prefer comfort care only?
- Permanent unconsciousness — If you're in a persistent vegetative state with no reasonable chance of recovery, what do you want?
- End-of-life care — Do you want a feeding tube? A ventilator? Resuscitation (CPR) if your heart stops?
These are hard questions. But answering them now—on your terms, when you're healthy and clear-headed—is far better than leaving it to a doctor and a panicked family member to figure out in real time.
What a Living Will Can and Can't Do
A living will is powerful, but it has limits. It only takes effect when you're incapacitated and unable to communicate your own decisions. If you're conscious and can speak for yourself, the living will steps back—you're always in charge of your own care as long as you're able to be.
It also can't cover every possible medical scenario. That's exactly why most people pair it with a healthcare surrogate designation.
Healthcare Surrogates: Naming Someone to Speak for You
A Healthcare Power of Attorney—also called a healthcare proxy or healthcare surrogate designation, depending on the state—is a legal document that names a specific person to make medical decisions on your behalf if you're unable to make them yourself.
This person is called your healthcare agent or healthcare surrogate. They step in when you can't, and their job is to advocate for what you would want—not necessarily what they want.
Choosing the Right Person
This is the most important decision in the whole process, so take it seriously. Your healthcare surrogate should be someone who:
- Knows you well and understands your values, not just someone you trust in general
- Can handle pressure — medical crises are stressful, and this person may have to make difficult calls while also grieving
- Will actually follow your wishes even if they personally disagree with them
- Is available and accessible — a close friend who lives across the country may not be the best choice if family is nearby
It doesn't have to be a spouse or a family member. It just has to be the right person. And it's worth having a real conversation with them before you name them—make sure they understand your wishes and are willing to carry them out.
What a Healthcare Surrogate Can Do
Once named, your healthcare surrogate has broad authority to make medical decisions for you. That includes:
- Consenting to or refusing medical treatment on your behalf
- Accessing your medical records
- Communicating with your doctors and medical team
- Making decisions about surgery, medications, and life-sustaining treatment
- Choosing your healthcare providers or facilities
Their authority only kicks in when you're deemed unable to make decisions for yourself—a doctor has to make that determination. Until then, you're still fully in control.
Why These Documents Matter More Than You Think
Here's a scenario that plays out more often than people realize: someone is in a serious accident and ends up unconscious in an emergency room. They have strong feelings about end-of-life care—maybe they've talked about it with their partner for years. But without a legal document, the hospital can't act on those conversations. If family members disagree about what to do, it can turn into a legal dispute. Courts get involved. It gets messy, expensive, and painful for everyone—at the worst possible time.
Advanced directives prevent that. They take the guesswork out of an already devastating situation and give your family permission to grieve instead of fight.
They also protect people who aren't married. If you're in a long-term relationship but not legally married, your partner has no automatic legal authority to make medical decisions for you. Without a healthcare surrogate designation, that decision could default to a parent or sibling you're estranged from. The same applies to close friends, unmarried partners, or anyone else who isn't a legal next of kin.
How to Set These Up in Arizona
Arizona has specific rules for advanced directives, and the documents need to meet certain legal requirements to be valid.
For a Living Will in Arizona:
- Must be signed by you (the person making it)
- Must be witnessed by two adults, or notarized
- Witnesses cannot be your healthcare provider, an employee of your healthcare provider, or someone who would inherit from your estate
For a Healthcare Power of Attorney in Arizona:
- Must be signed by you
- Must be witnessed by one adult or notarized
- The person you're naming as your agent cannot be your witness
Once your documents are completed:
- Give a copy to your primary care doctor and have it placed in your medical file
- Give a copy to your named healthcare surrogate
- Keep a copy somewhere accessible at home—not locked in a safe deposit box no one can get to in an emergency
- If you're ever hospitalized, bring a copy with you
A Few Things Worth Knowing
You can change your mind. Advanced directives aren't permanent. You can revoke or update them at any time as long as you're mentally competent to do so. Life circumstances change—relationships end, health situations evolve, your values shift. Review your documents every few years or after any major life event.
These are different from a Do Not Resuscitate (DNR) order. A DNR is a specific medical order signed by a physician that instructs emergency personnel not to perform CPR. It's narrower in scope than a living will, and it's a separate document. Your living will can express your wishes about resuscitation, but a DNR is the document that actually carries that instruction in a medical emergency.
"POLST" is another document to know about. In Arizona, a Physician Orders for Life-Sustaining Treatment (POLST) form is a medical order—not just a directive—that travels with you across care settings. It's typically used for people who are elderly, seriously ill, or in declining health. If that applies to you or someone you're caring for, ask a doctor about it.
Doing nothing is also a choice—just not a good one. Without these documents, medical decisions default to whoever the law designates as next of kin, in a specific legal order. That person may not be who you'd choose. And they'll be making one of the hardest decisions of their life without any guidance from you.
The Bottom Line
Advanced directives aren't about preparing to die. They're about making sure that if something unexpected happens, the people around you know exactly what you want—and have the legal authority to make it happen. It's one of the clearest acts of love and clarity you can offer the people closest to you.
The documents aren't complicated. The conversations that go along with them might be harder—but they're worth having. Most people who do it say they feel relieved once it's done, not sad.
Don't put it off because it feels uncomfortable. Put it in place because you care about what happens.
