Advance Directive vs Living Will vs Health Care Proxy

By The ClearLegacyGuide Editor · Updated September 10, 2026

An advance directive is the umbrella term for any written instructions about your future health care. A living will and a health care proxy are the two parts that usually sit inside it — the living will says what treatment you would want, and the proxy says who decides when you cannot. Your state may use different names for these same ideas, which is where most of the confusion begins.

The one-line version

Document	What it does	Common other names
Advance directive	The umbrella term for all of the below	Advance health care directive, health care directive
Living will	Writes down the treatment you would and would not want	Directive to physicians, declaration, health care instructions
Health care proxy	Names the person who speaks for you	Health care power of attorney, medical power of attorney, durable power of attorney for health care

If you remember nothing else: the living will is the “what” and the proxy is the “who”. Together they are your advance directive.

What an advance directive actually is

An advance directive is simply your instructions for health care, written down before you need them. It is “advance” because you make it ahead of time, and “directive” because it directs your care team and your family.

In most states, one advance directive document does both jobs at once: it names your person and states your wishes. In a few states the two jobs are split across two separate forms. Either way, the goal is the same — to keep your choices in your own hands when you are too unwell to speak.

What a living will is

A living will is the part where you write down the treatment you would and would not want if you could not make decisions yourself. People usually write about things like:

• whether you would want life support if there were no hope of recovery,
• whether you would want a feeding tube, and for how long,
• whether you would want comfort care focused on relief rather than a cure.

A living will only takes effect when you cannot speak for yourself, and usually only in serious, end-of-life situations. Until then, you make every decision yourself.

The catch: not every state has one

This is the part that surprises people. New York has no living will statute at all. New Yorkers use a Health Care Proxy instead, and write their treatment wishes into that document. A handful of other states fold the living will’s job into a single combined form rather than keeping it separate.

So if you searched “how to get a living will” and your state’s website never uses that phrase, that is probably why. See our state-by-state table for what your state actually calls it.

What a health care proxy is

A health care proxy (also called a health care power of attorney or medical power of attorney) is the part where you name a person — your agent — to make health care decisions for you when you cannot make them yourself.

Your agent’s job is to follow the wishes you wrote down and, where you did not leave instructions, to decide as you would. Because no form can predict every situation, choosing someone who knows you well matters more than writing the perfect document.

A few things worth knowing:

• You can name a backup agent in case your first choice is unavailable.
• Your agent is not the same as the person who handles your money — that is a financial power of attorney, a separate document.
• You can change your agent at any time, as long as you are still able to make your own decisions.

How the three fit together

Think of it as two questions and one answer sheet:

1. “Who decides for me?” → the health care proxy.
2. “What do I want?” → the living will.
3. “Where do I write it down?” → the advance directive (the document that holds one or both).

Some states keep all of this on a single page. Others split it across two forms. The form itself tells you which parts apply where you live — which is why you should use the form for your state rather than a generic template.

Why your state’s name for it matters

The three terms above are the common ones, but state law decides the actual names — and the names are not interchangeable. A few examples we verified directly with each state’s official source:

• New York calls the whole thing a Health Care Proxy and has no separate living will law. The proxy is the document that counts.
• California does not require any specific form. State law only says your directive has to include certain provisions, so a hospital’s form can be just as valid as the state’s model.
• Pennsylvania does not issue a state form at all. Any written, signed, and witnessed document can serve as your directive.
• Georgia rolls everything into one combined document called the Georgia Advance Directive for Health Care.
• Texas calls a living will a Directive to Physicians and Family or Surrogates, and accepts a notary instead of witnesses on several of its forms.

None of these are quirks to memorize. They are the reason a form from one state may not work in another — and the reason we built a state-by-state comparison rather than handing you a single template.

Do I need all of them?

In practice, yes — you want both a “who” and a “what” covered. But you usually do not need three separate documents. In most states a single advance directive form covers both, and the form itself shows you where to write each part.

The one combination to avoid: a living will with no named person. If you only write down treatment wishes and never name an agent, someone still has to make the calls your form did not anticipate. Naming a trusted contact who knows your thinking is what makes the rest actually work.

How to sign it so it sticks

This is the step people get wrong, and it is the step you cannot shortcut. Witnessing and notary rules differ by state and by document. Some states require two witnesses. Some accept a notary instead. Some require both. Some disqualify certain people — your agent, your relatives, your doctor — from being a witness.

You do not need to learn these rules. The form you download states exactly what it needs, usually on the signature page. Follow the form in front of you, not a summary you read online — including this one. If the form says two witnesses, find two witnesses. If it says notary, find a notary.

A form signed the wrong way is often treated as if it were never signed at all.

Where to keep it

A signed directive only helps if someone can find it. Once yours is complete:

• Give a copy to your health care agent and a backup.
• Give a copy to your doctor and ask them to scan it into your medical record.
• Keep the original somewhere reachable — not in a safe deposit box that needs a bank visit during an emergency.
• Write down where the original lives on your master checklist, so your family knows it exists.

A surprising number of completed directives are never used, simply because no one could locate them in time.

Frequently asked

Is a living will the same as a regular will?

No. A regular will (or “last will”) handles your money and belongings after you pass. A living will handles your health care while you are still here but too unwell to speak. They are completely separate documents.

Does an advance directive cover my money and bank accounts?

No. It only covers health care decisions. To let someone manage your finances, you need a separate financial power of attorney — and to handle what happens to your accounts afterward, you need a will. See our step-by-step guides for how these fit together.

Can I change my mind later?

Yes. You can update or cancel your advance directive at any time, as long as you can still make your own decisions. Tell your agent, your doctor, and anyone with a copy, and replace the old ones. A new signed document usually overrides the old one.

Which family member should I name as my agent?

Whoever knows your wishes best and will follow them even under pressure — which is not always your closest relative. The best agent is calm in a crisis, lives near enough to show up, and is willing to push for what you wanted. Name a backup in case your first choice cannot serve.

What if I move states?

Review it. A directive valid in one state is usually respected in another, but the safest move is to complete the form for your new home state. Our state comparison links to each state’s official form.

Next step

Once your directive is signed and stored, the only thing left is to tell one person where it is. The free Checklist Builder takes about five minutes and leaves you with a single page your family can actually use — including a line for “where I keep my advance directive.”
