What's the Difference Between an Advance Directive and a Living Will?
An advance directive is a legal document that takes effect only if you can't make your own medical decisions. It has two pieces: a living will (which treatments you would or wouldn't want) and a healthcare power of attorney, the person who decides for you. You can create both for free, without a lawyer; forms vary by state, so use your state's form and store it where it can be found. Families who have these documents describe the same relief — in a terrible moment, they weren't guessing or arguing.
Quick answer
An advance directive is a legal document that takes effect only if you can't make or communicate your own medical decisions. The two main kinds are a living will (which treatments you would or wouldn't want) and a healthcare power of attorney / proxy (the person who decides for you). You can create both for free without a lawyer. A POLST/MOLST is a separate medical order for people who are seriously ill. Laws and forms vary by state, so use your state's form and store it where it can be found.
What an advance directive is
An advance directive is a set of legal documents that only take effect if you become unable to make or communicate your own medical decisions — after a serious accident or illness, for example. While you can still speak for yourself, you remain in charge; the directive simply waits in the background as your backup plan and your voice.
A plain-English guide, not legal or financial advice
This article explains how these rules generally work so you can ask better questions — it isn't legal, financial, or tax advice, and the details vary. For your own situation, check the primary sources linked below and, where it matters, work with a qualified attorney or advisor.
The two main pieces: a living will and a healthcare proxy
- A living will states which medical treatments you would or wouldn't want — things like resuscitation, mechanical ventilation, tube feeding, or comfort-focused care — and under what conditions. It speaks for you about the care.
- A healthcare power of attorney (also called a healthcare proxy or agent) names the person who will make medical decisions for you when you can't. This is the same document discussed in our guide to powers of attorney — the healthcare side of it.
Most people want both: the living will guides the decisions, and the proxy is there to handle the many situations no document could anticipate.
You don't need a lawyer — and it's free
This is the part that surprises people. You can complete advance directives yourself, at no cost. There are free, plain-language tools to walk you through it — the NIA-funded PREPARE for Your Care program offers free advance directives in English and Spanish, and many states publish their own free forms. A lawyer can help if your situation is complex, but they aren't required.
POLST and MOLST: a different document for serious illness
You may run into POLST or MOLST (Physician/Medical Orders for Life-Sustaining Treatment). These are not the same as an advance directive — they're actual medical orders, signed by a clinician, that emergency responders and hospitals can act on immediately. They're meant for people who are seriously ill or near the end of life, and they supplement an advance directive rather than replace it. If you're generally healthy, a living will and a healthcare proxy are what you need now.
Medicare covers advance care planning — free at your wellness visit
You don't have to do this alone. Medicare Part B covers voluntary advance care planning, and it costs you nothing when it's done as part of your yearly ‘Wellness’ visit (or your ‘Welcome to Medicare’ visit) and your provider accepts assignment. Ask for it by name when you book. If the same conversation happens alongside other medical treatment instead, it's billed like any other service — the Part B deductible ($283 in 2026) and 20% coinsurance apply. Either way it's a chance to talk your wishes through with your doctor and get help completing your directive.
Four different documents get lumped together as “end-of-life paperwork,” and mixing them up is how families end up with the opposite of what they asked for. The real dividing line isn’t what each one says — it’s who signs it, and whether paramedics are allowed to act on it. One more thing the table can’t show: a POLST is meant for people who are seriously ill or frail. If you’re healthy, an advance directive is the right document and a POLST is not.
| Document | Who signs it | When it takes effect | Who is bound by it | Does it travel to another state? |
|---|---|---|---|---|
| Living will (a type of advance directive) | You, plus witnesses or a notary depending on your state. No doctor signature. No lawyer required. | Only when you can no longer communicate your own wishes. While you can still speak for yourself, it does nothing. | Your doctors and family use it as guidance. NIA is blunt that an advance directive is legally recognized but not legally binding — a provider whose conscience, institutional policy, or accepted standards conflict with it must tell your proxy and consider transferring your care. | Generally yes, but the receiving state’s rules govern. Most states recognize a directive validly executed elsewhere, though it will likely be interpreted under the law of the state where it is used. Re-execute if you move. |
| Healthcare power of attorney (healthcare proxy; durable POA for health care) | You, plus witnesses or a notary depending on your state. No doctor signature. | When you are unable to make or communicate healthcare decisions yourself. The exact trigger is set by state law. | Your named proxy gains authority to decide for you, and the care team works with that person. Same caveat as a living will: recognized, but not absolutely binding on a provider. | Same answer, same caveat. Because states differ on witnessing, agent qualifications and required language, the safest move is a fresh form in each state where you spend real time. |
| POLST / MOLST (portable medical orders; also POST) | A clinician signs it — that signature is what makes it valid. Most states and the national form also require you or your surrogate to sign. You cannot fill one out on your own. | Immediately, as a standing medical order. EMS and other providers can act on it on the spot, and it also guides day-to-day care decisions. | Healthcare professionals across settings, including EMS in an emergency. It is a medical order, not a statement of preferences. | Most likely yes, with some limitations, per National POLST. Carry it when you travel. If you move, bring it to your first appointment with a new provider and get your wishes onto that state’s form. |
| Out-of-hospital DNR (non-hospital DNR; honored as a bracelet or necklace in some states) | You or an authorized surrogate, plus the attending physician, plus two witnesses or a notary — the pattern in Texas, and typical of how states handle it. | Immediately on the date it is executed, for care outside a hospital. | EMS and out-of-hospital providers. Critically: a DNR written in a hospital chart does not carry over to home. Without an out-of-hospital DNR, EMS is obligated to attempt full resuscitation — Texas guidance states EMS will not consider other written documents, even from a doctor. | Varies by state and cannot be assumed. Some states accept out-of-state DNR forms — Texas expressly does — but many do not. Get the receiving state’s own form. |
Where to keep it (and where not to)
A directive nobody can find in an emergency doesn't help. The guidance is consistent:
- Keep the original somewhere safe but easy to reach — not in a safe-deposit box, which your family may not be able to open in time.
- Give copies to your healthcare proxy, your doctor, and close family.
- Take a copy to the hospital any time you're admitted.
- Carry a wallet card noting that you have a directive and who your agent is.
- Check whether your state has an advance-directive registry.
Keep it current — and re-check it if you move
Review your directive after any major life change — a diagnosis, a divorce, the death of the person you named as proxy. And because advance-directive laws and accepted forms vary by state, a document valid where you signed it may need to be redone if you move. Recording where the current version lives — and who has copies — is exactly what an end-of-life planner is built to do.
Put your advance directive in writing with Trust & Will
A directive only works if the hospital can see it and your agent can pull your records. Trust & Will's Will Plan ($199, 2026) includes the directive, the medical power of attorney, and the HIPAA authorization — the piece that gets skipped, and the reason a named agent still gets stonewalled at the records desk. Updating it later runs $49/year after the first. Code EXCLUSIVE10 takes 10% off.We may earn a commission if you buy through this link — at no extra cost to you.

Once your wishes are written down
Make sure they'll be found and followed
A directive in a safe-deposit box is a directive nobody reads in the ER. The End of Life Planner records where yours lives, who your healthcare proxy is, and the wishes your family may have to act on — so the afternoon you spent on this still counts at 2am in a hospital corridor.

Common questions
If I’m in a coma, who decides whether to keep me on a machine?
Whoever you named in a healthcare power of attorney — and if you named no one, state law picks for you, typically your spouse, then adult children, then parents. A living will tells that person and your doctors which treatments you would and wouldn’t want; the healthcare power of attorney names the human being who applies your wishes to a situation no document anticipated. Most people complete both, because between them they cover the two questions a hospital will actually ask.
I already have a will. Doesn’t that cover this?
No. A will only takes effect after you die and only controls your property — it has no authority over your medical care while you’re alive. An advance directive is the opposite: it operates only while you’re living and only when you can’t speak for yourself, and it ends at death. You need both documents, and neither substitutes for the other.
Do I need a lawyer, and what does this cost?
No lawyer, and it can cost nothing. You can complete a living will and healthcare power of attorney yourself on your state’s form; Medicare Part B also covers a voluntary advance care planning conversation with your doctor, at no cost to you when it’s part of your Welcome to Medicare or yearly Wellness visit. A lawyer is useful for complicated family or estate situations, but is not required for a valid directive.
My father is in the hospital right now with nothing in writing. Is it too late?
Not if he can still understand and communicate his choices — hospitals complete these documents at the bedside routinely, and you can ask a nurse, social worker or the palliative care team today. If he can no longer make decisions, nobody can sign a directive for him; the hospital will turn to whoever state law designates as the decision-maker. Ask specifically who that is under your state’s law, so the family isn’t guessing at 2am.
My mother had said she didn’t want to be resuscitated, but the paramedics did CPR anyway. Why?
Because a living will is not a medical order, and emergency responders cannot act on one. Paramedics are trained to attempt resuscitation unless they see a clinician-signed order — a DNR or a POLST/MOLST form — and a living will sitting in a drawer doesn’t meet that bar. For someone seriously ill or frail, that signed medical order, kept somewhere visible like the refrigerator, is what actually changes what happens in the first five minutes.
What’s a POLST, and do I need one?
A POLST (or MOLST, depending on your state) is a portable medical order signed by a clinician after a conversation with the patient — and if you’re generally healthy, you don’t need one. National POLST is explicit that it’s meant for people with a progressing serious illness or frailty due to aging, and that for healthy adults an advance directive is the preferred tool. A POLST also can’t name your decision-maker, so it supplements an advance directive rather than replacing it.
We’re moving to another state to be near the kids. Does the directive we signed back home still work?
Generally it will be honored, but the law of the state where you’re treated governs how it’s interpreted and what formalities it needs — so re-execute on your new state’s form after you move. The National Institute on Aging treats moving out of state as one of the events that should trigger a review and update of your directives. Re-doing them costs nothing and removes the argument at the worst possible moment.
I signed one years ago and nobody knows where it is. Does that matter?
Yes — a directive nobody can find is functionally the same as not having one. Give copies to your healthcare proxy, your doctor, and the family members most likely to be at the hospital, and keep your own copy somewhere findable, not in a safe deposit box your family can’t open. Then review the whole thing about once a year, and after any major health change.
