Which document is this, really
Maine’s law never actually uses the words “living will.” The Uniform Health Care Decisions Act creates a single defined term, the advance health care directive, and builds it out of two components you can use separately or together. The first is the individual instruction, where you say what treatment you do or do not want; the statute lets you give it orally or in writing, with no witness and no notary attached, though an oral one is valid only if you make it to a health care provider or to someone who could serve as your surrogate. The second is the power of attorney for health care, the document that names your agent, the person who decides for you once you cannot. Maine’s optional printed form combines both into one document, but nothing requires that: you can sign an individual instruction alone, or a power of attorney alone.
The asymmetry between the two is the thing to understand before you sign anything. An individual instruction carries no witness or notary requirement at all. A power of attorney for health care does, in the form of two witnesses signing in person alongside you. Most people end up wanting both pieces, their wishes on paper and someone named to act on them, which is exactly what the combined form, and Myend’s Healthcare Directive, are built to produce.
Who can make a Maine advance health care directive
You need to be an adult, 18 or older, to sign either part of Maine’s directive. Maine’s health care law does not define “adult” on its own; it relies on the state’s general definition, an adult being someone who has reached 18. What the health care law does add on its own is an emancipated minor: Maine writes emancipated minors into eligibility for both the individual instruction and the power of attorney directly, rather than leaving them out until a court says otherwise. Past the age line, what actually matters is capacity: whether you understand what the document says, what it does, and what naming an agent means, at the moment you sign it. That is a judgment made in the room at signing, not a diagnosis or certificate you need to produce in advance.
Signing it so it counts
Because Maine’s advance health care directive is really two components with two different formalities, treat them separately even if you sign both at the same sitting.
Your individual instruction
If all you want to do is write down, or say aloud, what treatment you do and do not want, Maine asks for no witness and no notary. An individual instruction can be oral or written. Saying it aloud carries one condition the written version does not: an oral instruction is valid only if you make it to a health care provider, or to someone who could serve as your surrogate under Maine’s own surrogate rule. Most people still put it in writing, since a spoken instruction is only as reliable as whoever was in the room to remember it later.
Your power of attorney for health care
Naming your agent is where the formality shows up.
- 1You sign, in person
You sign the power of attorney for health care yourself, in ink. Maine’s law says plainly that signatures of the principal and witnesses must be made in person and not by electronic means, notwithstanding any other Maine law that would otherwise validate an electronic or digital signature.
- 2Two witnesses sign too
The power has to be in writing and signed by you and by two witnesses, with all three signatures made in person. Maine’s statute sets no age for a witness and names no category of person barred from witnessing, so there is no disqualification list to work through here, unlike many other states.
- 3No notary needed
Maine does not ask for a notary and does not offer one as a substitute for the two witnesses. A notarized power of attorney is still a document Maine law recognizes, but notarization is not what makes it valid; the two witnesses are.
Even where the law does not disqualify anyone, choosing two witnesses who are not your named agent and who will not inherit from you is still the safer practice, the same practice most other states require outright.
One narrow exception loosens the in-person rule. If you are isolated in a hospital or a residential health care facility because of an infectious disease, Maine allows the power of attorney to be signed over two-way audio and video instead: you review an unsigned copy first, sign it, and return the signed copy to be checked against what you reviewed, with a right to revoke on the spot if anything does not match. That exception does not apply once the directive is notarized, or in any other setting.
Naming your agent
The power of attorney for health care is where you name your agent, Maine’s own term for the person authorized to make health care decisions for you once someone has determined that you cannot make them yourself.
Maine disqualifies one narrow group. Unless related to you by blood, marriage, or adoption, an agent cannot be the owner, operator, or an employee of the residential long-term care institution where you are receiving care. Beyond that single rule, Maine’s statute does not hand you a list to sort through, so anyone else you trust with the job can serve.
How much authority they get is your call too. Maine’s own form has a place to limit it; leave that space blank and your agent may make all health care decisions for you, including directing the provision, withholding, or withdrawal of artificial nutrition and hydration and every other form of life-sustaining treatment. Whatever you write there is what your agent is held to, alongside your instructions and your other wishes as far as your agent knows them.
When it takes effect
Unless your power of attorney says otherwise, your agent’s authority turns on only once someone determines that you lack capacity to make your own health care decisions, and it turns off again on a determination that you have recovered capacity. Maine names three people who can make that call: your primary physician, a court, or, if you have included a directive about mental health treatment, a person qualified to conduct that kind of examination. Maine does not ask for a terminal-condition certification the way some older state laws do; a capacity determination is the trigger, not a diagnosis of a terminal or irreversible condition. You can also choose otherwise in the document itself, and Maine’s own form carries a box that starts your agent’s authority immediately instead. Either way the power of attorney is durable, so it stays in effect after you lose capacity rather than lapsing at the moment you need it most.
If you are pregnant
The word pregnant does not appear anywhere in Maine’s Uniform Health Care Decisions Act: not in the definitions, not in the section that sets out your directive, not even in the optional printed form. Maine imposes no automatic pause on your directive if you are pregnant. Whatever you have written, or told your agent, controls exactly as written.
Changing or cancelling it
You can revoke your individual instruction, or any part of your directive other than the agent designation, at any time and in any way that makes clear you mean to revoke it, spoken or written; Maine asks for no particular formality here. Cancelling the agent designation itself is held to a stricter standard: you need a signed writing, or you need to tell your supervising health care provider directly, that you are revoking it. Once you have told anyone, a health care provider, your agent, a guardian, or a surrogate, that person is required to pass the news on to your supervising provider and to any health care institution where you are being treated.
Two revocations happen without you doing anything at all. A decree of annulment, divorce, dissolution of marriage, or legal separation revokes an earlier designation of your spouse as agent, unless the decree or the power of attorney says otherwise. And a later advance health care directive revokes an earlier one to the extent the two conflict, which is why replacing a directive outright is cleaner than layering a new one on an old one.
Making sure it is found
Nothing in Maine’s Uniform Health Care Decisions Act sets up a central place to file your directive, and no state office appears to run one. Without a registry to lean on, getting the paperwork in front of the right people is on you: hand a signed copy to your agent and to your physician before you ever need either one to act on it, and put another wherever the hospital you would most likely use keeps that kind of thing on file. Store the original somewhere obvious enough that your own household does not have to search for it during an emergency.
Maine’s reciprocity rule is unusually clean. An advance health care directive that was valid where you signed it is valid in Maine too, without also being measured against Maine’s own witness rule. If you signed your directive in another state and are later treated in Maine, that earlier document still works here.
This is not a POLST
Maine’s medical orders program is generally known as POLST Maine, short for Physician Orders for Life-Sustaining Treatment, and is coordinated through the Maine Hospice Council and Center for End-of-Life Care rather than created by the Uniform Health Care Decisions Act. It is not the same kind of paperwork as your advance health care directive. A POLST is a set of specific medical orders, signed by a clinician together with someone already living with a serious illness, meant to travel with that person between home, hospital, and ambulance. Your advance health care directive is something you put in place well before any of that, to say what you want and name who decides if you cannot. Myend prepares the directive. It does not, and cannot, produce a POLST, because that has to come from a treating clinician.
What is different about Maine
Maine’s directive is really two rules living under one law: writing down what you want takes no formality at all, and naming who decides for you takes a real signing, witnessed and in person.
Most states hold the whole directive to one signing standard. Maine splits it: the individual instruction, the part that carries your treatment wishes, needs no witness, no notary, and not even paper, as long as a spoken one goes to a health care provider or to someone who could act as your surrogate. The power of attorney for health care, the part that names your agent, needs two witnesses watching you sign, in person, with electronic signatures barred outright. Skip the power of attorney and you have written wishes with nobody formally empowered to enforce them. Skip the instruction and you have an agent with no idea what you actually want. Most people are better served doing both, which is exactly what the combined form is for.
Maine also says nothing at all about pregnancy, in either direction. There is no clause suspending your directive, and no clause asking you to state your wishes about pregnancy specifically. Whatever you have written stands on its own regardless.
And Maine’s in-person signing rule is stricter than it looks at first glance. Electronic signatures are barred for the power of attorney even where other Maine law would otherwise allow them, with one narrow carve-out for a principal isolated in a hospital or care facility during an infectious disease outbreak, signed over live two-way video instead of paper. Outside that one situation, both you and your witnesses need to be in the same room.
