Picture a Tuesday evening. You're at your kitchen table with a cup of tea, the radio low, and a friend's voice on the phone telling you about her husband's hospital stay. Then she says something that lands: "The doctors kept asking what he wanted, and nobody had the answer in writing." You look around your quiet kitchen and wonder who would answer that question for you.
That wondering is not gloom. It's care for the person you are today. Here is the short answer to the question behind it. An advance directive is a legal document that records your wishes and can name the person who speaks for you. A POLST is a medical order, signed by a clinician, for people who are seriously ill or frail. Most healthy adults need the first. Only some need the second. Both can sit side by side.
TL;DR
- An advance directive (which can include a living will and a health care proxy) is a legal document every adult can complete while they can still decide for themselves.
- A POLST is a portable medical order for people with serious, life-limiting illness or advanced frailty. It is completed with a clinician and works like a doctor's order.
- A POLST complements an advance directive. It does not replace it, and a living will is one kind of advance directive.
- POLST forms, names and rules differ by state, so use the form your own state approves.
- If you live alone, the person you name matters as much as the paperwork. Choose them and talk with them first.

Two documents, two different jobs
Think of it this way. One document tells your story. The other gives instructions for a specific moment.
An advance directive is completed while you have the capacity to make decisions. According to the National POLST form guidance, it may appoint a surrogate and spell out your treatment preferences. It speaks for you when you can't speak for yourself, and it's written in general terms: what matters to you, what kind of care you would or wouldn't want.
A POLST is different. The same guidance describes it as a voluntary, portable set of medical orders. It takes effect once it is completed and signed, and healthcare professionals, including emergency personnel, can act on it. It's not a statement of values. It's a set of orders.
That's where the "legal document versus medical document" line you see all over search results comes from. The American College of Physicians toolkit puts it the same way: living wills and advance directives are legal documents that may identify a representative, while a POLST-type form is a medical order that does not name a surrogate.
Where the living will fits
People often ask about a POLST versus a living will, as if they were rivals. They aren't the same kind of thing at all. UCSF Health explains that a living will records medical wishes only. A healthcare power of attorney names the decision-maker only. An advance directive commonly combines the two: your wishes plus the person who decides if you can't.
So a living will is a piece of the advance directive family. A POLST sits in a different category altogether, because a clinician signs it and it becomes part of your medical orders.
A quick side-by-side
| Advance directive (including living will) | POLST | |
|---|---|---|
| What it is | Legal document | Medical order |
| Who it's for | Every adult with decision-making capacity | People with life-limiting illness or frailty due to aging |
| Who completes it | You, often with witnesses or a notary, depending on your state | You or your legal surrogate, together with a clinician, who signs |
| What it can do | Name a surrogate and describe your treatment preferences | Specify treatment choices, such as CPR or a level of care |
| Can emergency crews act on it? | Generally not | Yes |
| When it applies | When you can't speak for yourself | Once completed and signed |
The sources behind the table: the National POLST guidance covers who each is for and how a POLST takes effect. For emergency crews, the American Cancer Society says they can use a POLST but cannot adhere to an advance directive. For the signing differences, Nevada's health department says an advance directive generally needs two witnesses or notarization, while a POLST needs the patient or surrogate and an authorized practitioner to sign.
Who actually needs which one
Here's the reassuring part. If you're healthy and active, you don't need a POLST. The National POLST Collaborative says healthy people generally should use an advance directive. People who are seriously ill or have advanced frailty should talk with their provider about a POLST.
Arkansas says the same from the state side: all adults should have an advance directive regardless of health, while a POLST is useful for seriously ill, frail or hospice patients. New Jersey's guidance for providers recommends an advance directive for all adults and a POLST for those who are seriously ill or medically frail with limited life expectancy.
So if you're 58 and you just finished a long hike, the question is not "POLST or directive?" It's "who is my person, and do they know what I'd want?" If you're 84, living with advanced heart failure, and your doctor says another serious event is a real possibility, a POLST conversation belongs on your calendar, and your directive still stays in place.
What a conversation about wishes sounds like
Someone once described to me the afternoon she finally sat down with her neighbor of twenty years. They had split a fence, a lemon tree and a hundred pots of soup between them. She asked one question: "If I couldn't speak for myself, would you be willing to be the one who speaks for me?" Her neighbor teared up and said yes before she'd finished the sentence.
That's the real work of an advance directive. The form is the easy part. The harder, warmer part is a conversation with someone who knows you, so that when they read your words they can hear your voice.
If you live alone or have no children, this is where your own people come in: a close friend, a niece or nephew, a trusted neighbor, a member of your community. We've written about how to pick a health care proxy and name a backup, and about why solo agers benefit from setting up a proxy before they need one. Both are good places to begin if you haven't had that conversation yet.
Does a POLST override an advance directive?
Not in the way people fear. The two should say the same thing. A POLST is meant to complement your directive, as the American Association of Nurse Practitioners puts it, rather than replace it.
In the real world, though, life changes and documents can drift apart. You wrote your directive at 55 when you felt invincible. Then came a diagnosis and a new conversation with your doctor. If the two papers disagree, New Jersey's guidance says the care team should talk with you or your surrogate as soon as possible about your most current wishes and update the documents. If that can't happen before a crisis, they follow the most recent document. Arkansas directions likewise say to review the documents together and update them to resolve conflicts.
The practical takeaway is gentle: when something big changes, read both documents again, out loud if you like, and ask whether they still sound like you.
Do you need a DNR if you have a POLST?
Usually, no. A do-not-resuscitate order speaks only to CPR. A POLST can cover CPR and more. Nolo's legal guide notes that, like a DNR, a POLST tells emergency personnel whether to give CPR, and that it also includes directions about things like intubation, antibiotics and feeding tubes. Some people still keep a separate out-of-hospital DNR, and some states have specific rules about it. Nevada, for example, says emergency responders must attempt resuscitation unless a POLST or out-of-hospital DNR is available.
The question for your own doctor is simple: "In our state, does my POLST cover what I need in an emergency, or should I also have a separate order?"
What a POLST can and can't say
A POLST can record whether you want full treatment, selective treatment or comfort-focused care. It can also record choices about CPR and tube feeding, according to the American Cancer Society. The National POLST Collaborative adds that it can guide care beyond emergencies when you can't communicate.
That precision is its strength. It's also why it's built for people whose health makes those questions immediate. A POLST asks, "Given where your health is right now, what do you want us to do?" An advance directive asks a bigger, steadier question: "What matters to you, and who should speak up if you can't?"
Is POLST accepted in all 50 states?
Nearly, but not uniformly. The American Association of Nurse Practitioners reports that 43 states and Washington, D.C. have codified POLST programs or an officially recognized state form, while seven states lack an officially recognized single statewide form. Rules, including whether a nurse practitioner's signature counts, vary.
Names vary too. The National POLST site notes that states use POLST, MOLST, POST, MOST and LST. A 2019 study in the Journal of Palliative Medicine found active POLST participation in 48 of 51 jurisdictions examined, with real differences in the treatment options on the forms. Antibiotics appeared on 32 of 45 reviewed forms, for instance.
What does that mean for you? Use your own state's form, and ask your clinician about it. The National POLST Collaborative has warned that a generic national model form should not substitute for the state-developed or state-approved form. If you spend winters in another state, ask your clinician how that state treats your form.
Keeping it all alive, not filed away
An advance directive that sits in a drawer doesn't help anyone. A few simple habits make it real.
Give copies to your doctor and to the person you named. Nevada recommends giving copies to physicians and your health care agent, and submitting documents to a registry where one exists. The American College of Physicians suggests storing them in your medical record or another place that's easy to find, and reviewing them periodically. Annual review can help as health and preferences change.
A POLST has its own rhythm. The National POLST guidance says to review it whenever your condition or care setting changes, and at least annually. New Jersey recommends review after a transfer, a substantial health change or a change in your preferences. And Arkansas says a patient with capacity may revoke a POLST at any time. You are always the author.
If you live alone, one more small thing helps: make sure someone knows where your papers are and who to call. Our Advocacy Card is one way to carry that information with you.
Our perspective
We've sat with a lot of people at the very point you may be at now: curious, a little wary, and not sure which form is theirs. What we notice is that the paperwork rarely causes the worry. The worry comes from not knowing who would speak up.
We started Aging Solo Today because a solo life can be a complete life, and a complete life includes the people who would stand beside you if things changed. Documents matter, but they work best when a real person understands them and has agreed to carry them. So we tend to start with the person, not the form. Who knows you well? Who would you trust to say "this is what she'd want"?
From there, the directive follows naturally, and a POLST becomes a conversation with your doctor if and when your health calls for it. You don't have to do it all at once. You also don't have to do it alone, even if you live alone. We built our resources and our one-on-one sessions to make that conversation feel lighter, so you can get back to the parts of life you love.

A little help to get started
If you'd like to talk it through with someone who understands solo living, we offer the Solo Aging Clarity Session: a 45-minute Zoom conversation for personalized solo ager planning, for $97. It's a chance to sort out which of these documents fits your situation, who your people are, and what to tackle first, in a calm, unhurried way. This is guidance, not legal or medical advice, so it works alongside your attorney and your clinician.
You can book a Solo Aging Clarity Session whenever you're ready. If you'd rather browse first, our free checklists and resources are there for self-guided planning, and our guide to naming a surrogate decision maker is a good companion to this article.
FAQ
Is a living will the same as an advance directive?
Not quite. A living will records your treatment wishes. An advance directive is the broader category and often also names a person to decide for you, according to UCSF Health. Many people complete both parts together.
Can I fill out a POLST on my own?
No. A POLST needs a clinician's signature, plus yours or your legal surrogate's, as the National POLST guidance explains. It comes out of a conversation with your provider about your current health and goals. Ask your doctor or nurse practitioner whether it's right for you.
Do I need both?
If you're healthy, an advance directive is usually the right fit, per the National POLST Collaborative. If you become seriously ill or frail, your clinician may suggest adding a POLST. They work together, and the AANP describes the POLST as complementing the directive.
Does a POLST expire?
Not on a set date, but it should be reviewed. Review it whenever your health or care setting changes, and at least once a year. You can also change or revoke it at any time while you have capacity, as Arkansas directions note.
What if I live in one state and travel or move to another?
Rules differ by state, and the form should be the one your state approves. Ask your clinician how another state treats your documents before a long stay, and update them after a move.
The point of all this is a good life
Back at that kitchen table, the tea has gone cool. But something has shifted. You know the words now. You know that one form tells your story and another gives a clinician's orders. You know the real first step is a name: the person you'd ask.
Once that's settled, the quiet in the house feels different. Lighter. Your life is still yours to fill: a long dinner out for one, a trip you've been putting off, a new friend from the class downtown. The papers simply let you live all of it with a little more ease.
