Living will requirements in Louisiana

Louisiana calls its living will a Declaration, and the same paper can name your health care agent if you want it to. You must be an adult, 18 or older, and sign it in the presence of two witnesses; Louisiana does not ask for a notary. If you cannot sign in writing, the law also lets you make the Declaration orally or by any nonverbal means, still in front of two witnesses.

Which document is this, really

Louisiana’s living will has a plain statutory name most people never hear until they need it: the Declaration. It is a written, spoken, or otherwise expressed statement, made by the person the law calls the declarant, authorizing the withholding or withdrawal of life-sustaining procedures if a terminal and irreversible condition is ever diagnosed. The Louisiana Secretary of State’s own registry calls it the “Living Will Declaration,” and that is the label most people in Louisiana actually use.

Louisiana lets one Declaration do double duty. The law says the declaration “may, but need not,” follow the illustrative form the statute prints, and that it can include other directions, among them naming another person to make the treatment decision for you if you become comatose, incompetent, or otherwise unable to communicate. There is no separate statutory document you are required to fill out just to name that person; it can live inside the same paper as your treatment wishes.

Louisiana also recognizes a broader arrangement outside the Declaration’s narrow terminal-condition scope, generally called a mandate, that lets you give someone authority over your health care decisions more generally. Louisiana’s civil-law tradition, inherited from France and Spain, is where that concept comes from, and it is worth knowing the vocabulary even though, as the section further down explains, it does not change how your medical decisions actually get made. This is exactly what Myend’s Healthcare Directive prepares for Louisiana: one Declaration, carrying your wishes and, if you want, your choice of decision-maker.

Who can make a Louisiana Declaration

Louisiana asks that you be an adult, meaning 18 or older, to make your own Declaration. A minor cannot sign one for themselves. The law separately allows a spouse of full age, a parent, or a guardian to make a Declaration on behalf of a terminally ill minor, but that is a decision made for the minor by someone else, not the minor exercising the right personally.

Beyond the age line, capacity is the practical question: you need to understand what the Declaration says, what it does, and, if you are naming someone, what it means to give them authority over your treatment decisions, at the moment you sign it. That is not a medical certification you carry around, just an ordinary understanding of the document in front of you.

Signing it so it counts

Louisiana’s Declaration has one signing rule, and it applies whether or not you also use it to name a decision-maker.

  1. You sign

    You sign the written Declaration yourself.

  2. Two witnesses

    You sign in the presence of two witnesses. Louisiana does not offer a notary as an alternative; the two witnesses are the only route the law provides for a written Declaration.

  3. Who cannot witness

    A witness cannot be a relative of yours by blood or marriage, and cannot be anyone who would inherit any part of your estate if you died. Louisiana keeps that rule inside its definition of the word witness rather than in the signing section, which is why a reader who only reads the execution rules misses it, and that definition says nothing about your attending physician or the people who work at your hospital or care facility.

Witness one
Witness two

If you cannot sign in writing, Louisiana also lets you make the Declaration orally or by any other nonverbal means of communication, still in front of two witnesses. That route is only available once you have already been diagnosed with a terminal and irreversible condition, so it is a fallback for that moment, not something you can use while planning ahead in good health. Most people who plan ahead sign the written version.

Naming your agent

Whether you name a decision-maker inside your Declaration or through a separate mandate, Louisiana’s health care consent law calls that person an agent. The underlying legal instrument for the broader mandate is a Civil Code contract, and in Louisiana’s own civil-law vocabulary the appointed person is often called a mandatary, though the health care statute itself uses the word agent.

Louisiana writes this rule permissively rather than as a list of people who are barred. The Civil Code says even a person of limited capacity may act as a mandatary for matters they are able to contract for, and authority over health care has to be given expressly. The Declaration’s own designation power lets you name someone to make the treatment decision for you without attaching any condition to who that person is. Louisiana does know how to write exclusions when it wants them. If you never name anyone and a decision falls to the default order of family members instead, a spouse who is judicially separated from you, living with someone else as if married, convicted of a crime of violence against you that caused your condition, or found to have violated a protective order you obtained against them, is skipped in that order. Those exclusions attach to the automatic family hierarchy, not to an agent or mandatary you actually choose and name yourself.

Once your Declaration or your agent’s mandate takes effect, they can make the treatment decisions you have authorized, including whether life-sustaining procedures continue.

When it takes effect

Your Declaration applies once you become what Louisiana law calls a “qualified patient.” That means you have been diagnosed and certified, in writing, as having a “terminal and irreversible condition”: either a continual profound comatose state with no reasonable chance of recovery, or a condition caused by injury, disease, or illness that, within reasonable medical judgment, would produce death, where life-sustaining procedures would only postpone that moment. Two physicians who have personally examined you must make that certification, and one of them has to be your attending physician.

If you are pregnant

Louisiana does not set your Declaration aside automatically the moment a pregnancy is diagnosed. What the law gives instead is a rule for resolving genuine ambiguity in your Declaration: when a court or a physician has to interpret what your Declaration means, Louisiana’s stated policy is to interpret any ambiguity in favor of preserving life, including the life of an unborn child, but only where two things are both true at the same time. An obstetrician who examines you has to determine that the probable postfertilization age of the child is twenty weeks or more, and has to determine that your life can reasonably be maintained in a way that lets the pregnancy continue and the child be born alive. That finding also has to be communicated to your family and to anyone you have designated under the Declaration.

If your Declaration says clearly, in your own words, what you want to happen during a pregnancy, there is no ambiguity for this rule to resolve, and your stated wishes govern. The rule only steps in where the Declaration is unclear, and even then only once both medical findings above are made.

Changing or cancelling it

You can revoke your Declaration at any time, no matter your mental or physical condition, in any of three ways: destroying it yourself, or having someone else destroy it in your presence and at your direction, by cancelling, defacing, obliterating, burning, or tearing it; signing and dating a written statement that says you revoke it; or simply telling someone, or expressing by any nonverbal means, that you intend to revoke it.

A revocation takes effect once it reaches your attending physician, who has to record the date and time they were notified. If you had filed your Declaration with the Secretary of State’s registry, a written revocation notice has to be filed there too before the registry record is updated; a physician or facility that relies in good faith on your Declaration before that notation is made is protected for having done so.

Making sure it is found

Louisiana runs the Living Will Declaration Registry through the Secretary of State’s Elections Services division. Filing is optional, not a condition of your Declaration’s validity: it costs twenty dollars to register, another twenty for a certified copy, and five dollars to file a revocation notice. Registrants can also get a wallet identification card and, if they choose, an engraved “Do Not Resuscitate” bracelet. This registry is separate from Louisiana’s Will Registry, which exists for last wills and testaments, not for this document, so do not assume registering one covers the other.

Whether or not you register, give copies of your Declaration to your agent, your physician, and the hospital you are most likely to use, and keep the signed original somewhere your family knows to look. A Declaration nobody can find in the moment it matters does little good, registry or not.

If you signed your Declaration somewhere else, Louisiana treats a declaration validly executed under another state’s own law as validly executed here too.

This is not a POLST

Your Declaration is something you complete in advance, for a future you cannot yet see. A portable medical order, sometimes called a POLST, MOLST, or a similar name depending on where it is used, is a different kind of document: specific medical orders a clinician signs together with someone who is already facing serious illness, meant to travel with that person between hospital, nursing facility, home, and ambulance. If you are already being treated for a serious illness in Louisiana, ask your care team whether a portable order form is part of your care plan; that would be a separate document from your Declaration. Myend prepares the Declaration. It does not, and cannot, produce that kind of clinician-signed order, because that has to come from a treating physician.

What is different about Louisiana

Louisiana’s private law runs on the civil-law tradition of France and Spain, but the Declaration that carries your medical wishes reads like the living-will statutes of the other fifty states.

It is easy to assume that a state built on civil law would treat health care decisions differently too, the way Louisiana’s forced-heirship rules make its last will and testament genuinely unlike the other states’. That assumption does not hold here. The Declaration statute asks for a written or oral document, two ordinary witnesses, and nothing else, no notarial act, even though Louisiana is exactly the kind of state where a notary is the default way to make many other documents binding. Civil law shaped the vocabulary around naming a decision-maker; it did not change the outcome for your medical care.

The vocabulary is still worth knowing. The statute calls you the declarant. Where you appoint someone under the broader mandate arrangement rather than inside the Declaration itself, Louisiana’s Civil Code calls that contract a mandate and, in its own civil-law usage, the person you appoint a mandatary, even though the health care consent statute prefers the plainer word agent. None of those labels change what the appointed person can actually decide.

Two more things set Louisiana apart. Its rule about who may hold the role is written permissively rather than as a list of exclusions: the Civil Code says even a person of limited capacity may act as mandatary for matters he is capable of contracting for. And Louisiana’s pregnancy provision is not a flat pause the way it is in several other states; it is a two-part interpretation rule that only activates when your Declaration is ambiguous and an obstetrician makes two specific findings, gestational age and the chance of a live birth, together.

Common questions

Does a Louisiana living will have to be notarized?
No. Louisiana’s Declaration only ever needs two witnesses, whether you sign it in writing or make it by speaking or another nonverbal means instead. Louisiana is a civil-law state, where notarial form is the usual way to make many other documents binding, but the law that governs this one never mentions a notary at all, and the illustrative form the statute prints has two witness lines and no notary block.
What is the difference between Louisiana's Declaration and a health care power of attorney?
The Declaration is the document that carries your treatment wishes if you are ever diagnosed with a terminal and irreversible condition, and Louisiana lets that same paper name a decision-maker for you, if you choose to use it that way. Louisiana separately recognizes a broader arrangement, generally called a mandate, that lets you give someone authority to make health care decisions for you outside that narrow terminal-condition scope. In Louisiana’s civil-law vocabulary the person appointed under a mandate is often called a mandatary, though the health care consent law itself uses the word agent when it talks about health care decisions specifically.
How many witnesses does a Louisiana Declaration need, and who cannot be one?
Two. Louisiana defines a witness as a competent adult who is not related to you by blood or marriage and who would not inherit any part of your estate if you died. The rule sits in the definitions section rather than the signing section, and that definition says nothing about your attending physician or the people who work at your hospital or care facility.
Who can be my agent in Louisiana, and what can they decide?
Louisiana writes this rule permissively rather than as a list of exclusions. The underlying legal concept is a mandate, and the Civil Code says even a person of limited capacity may act as a mandatary for matters they are able to contract for, with authority over health care having to be given expressly. The Declaration’s own designation power attaches no condition to who you pick. Once your Declaration, or your agent’s mandate, takes effect, they can make the treatment decisions you have authorized, including whether life-sustaining procedures continue.
Is a Louisiana Declaration the same as a POLST?
No. A Declaration is something you complete in advance, for a future you cannot yet see. A portable medical order, if your care team in Louisiana uses one, is a different kind of document: specific orders a clinician signs together with someone who is already seriously ill, meant to travel with that person between hospital, nursing facility, home and ambulance. Myend prepares the Declaration. It does not produce that kind of clinician-signed order, and cannot, because that has to come from your treating physician.
If I signed my declaration in another state, does Louisiana honor it?
Yes, if it was validly executed under that other state’s own law. Louisiana treats a declaration properly signed elsewhere as validly executed here too, so moving to Louisiana, or being treated here while traveling, does not by itself void a directive you made somewhere else.
How do I make sure my Louisiana declaration is found when it matters?
Louisiana runs the Living Will Declaration Registry through the Secretary of State’s office. Filing is optional, costs twenty dollars, and gets you a wallet card and, if you want one, an engraved bracelet noting that a declaration is on file. It is separate from Louisiana’s Will Registry, which is for last wills and testaments, not this document. Whether or not you register, give copies to your agent, your physician, and the hospital you are most likely to use.
Do I need a lawyer to make a Declaration in Louisiana?
No. Louisiana’s own illustrative form is optional, not mandatory, and the law does not require an attorney to prepare or witness it. Myend’s Healthcare Directive prepares a Declaration formatted to Louisiana’s requirements at no cost, so the only work left is finding two witnesses.
