Mississippi Living Will: Statutory Form, Witnesses, and Agents

A Mississippi living will is a written statement of the medical treatment you do and don’t want if you can no longer speak for yourself. To be valid, it has to be in writing, dated, signed by you (or by someone signing at your direction in your presence), and — if it also names a healthcare agent — either witnessed by two qualifying adults or acknowledged before a Mississippi notary public. The Uniform Health-Care Decisions Act at Mississippi Code Sections 41-41-201 through 41-41-229 sets the rules and provides a free statutory form that satisfies every requirement.¹

Who Can Make One

Any adult or emancipated minor in Mississippi can create an advance directive. The document must be written, dated, and signed by you, or by another person signing at your direction and in your presence.²

Written treatment instructions on their own — the “living will” part — don’t require witnesses under the statute. Witnessing rules kick in when the same document also names a healthcare agent, which most people include and which the state’s form assumes.

Witnessing or Notarizing the Document

If your directive includes a healthcare power of attorney, Mississippi accepts either of two methods.²

Two adult witnesses, both personally known to you and present when you sign or acknowledge your signature. Neither can be a healthcare provider, an employee of a healthcare provider or facility, or the agent you’re naming. At least one of the two must also be someone who isn’t related to you by blood, marriage, or adoption and has no claim to your estate.

The notary route is often faster. Finding two adults who meet every disqualifier can be harder than it sounds, especially in a hospital or care facility, and a notary visit sidesteps the problem.

One restriction on who can serve as your agent catches people off guard: unless the person is related to you by blood, marriage, or adoption, an owner, operator, or employee of a residential long-term care facility where you live cannot be your healthcare agent.²

Using the State’s Statutory Form

Mississippi Code Section 41-41-209 contains the official advance directive form. You aren’t required to use it, but it’s built to satisfy every legal requirement and covers the choices most people need to make.¹

The form asks you to say whether you want life-prolonging treatment withheld in three situations: an incurable condition expected to result in death within a relatively short time, permanent unconsciousness, or a case where the risks and burdens of treatment outweigh the expected benefits. It also asks about artificial nutrition and hydration separately, because many people feel differently about tube feeding than about other interventions.¹

Using the statutory form reduces the chance that a hospital will question whether your directive complies with Mississippi law. An attorney can tailor language for unusual situations, but for straightforward cases the form does the job at the cost of printing and either witnessing or notarization.

Add a Healthcare Agent, Not Just Instructions

A living will only speaks to situations you anticipated. When a medical question comes up that your written instructions don’t address, doctors have nothing to go on. Naming a healthcare agent under a power of attorney fills that gap: your agent can make any healthcare decision you could have made yourself when you had capacity.²

The state’s form combines both in one document for a reason. Write down your specific preferences, and name someone who knows your values well enough to handle everything you didn’t predict. Have that person read the living will before anything happens, so there’s no confusion later.

Changing or Revoking Your Living Will

You can revoke your directive, or any part of it, at any time and in any way that shows you intend to revoke. That can mean a written statement, telling your doctor, or tearing up the document. No witnesses are needed to revoke your written instructions.³

Removing your agent takes a bit more formality. You have to either sign a written revocation or personally tell your supervising healthcare provider. A later directive that conflicts with an earlier one automatically replaces the older version to the extent of the conflict.³

Divorce is the revocation people miss. A divorce, annulment, or legal separation revokes a former spouse’s designation as your healthcare agent unless the court decree or the power of attorney says otherwise.³ If you divorce and still want your former spouse to serve, you need a new directive that says so plainly.

When you revoke or update, tell your doctors and anyone holding a copy. A provider, agent, or surrogate who learns of a revocation has to pass that information promptly to your supervising physician and to any facility where you’re receiving care.³

Where to Keep It and Who Needs a Copy

Mississippi doesn’t run a statewide advance directive registry, so distribution is on you. A directive no one can find during a crisis doesn’t help.

Your healthcare agent, and any alternate agents you named.
Your primary care physician, who can put it in your medical record.
Close family members likely to be present in an emergency.
Any hospital or facility where you routinely receive care.

A scanned copy on your phone or in a shared cloud folder gives your agent quick access. Some private online registries let you upload the document so emergency room staff can pull it electronically. The point is that two or three people besides you know it exists and where to find it.

Providers presented with a valid directive have to follow your instructions, or your agent’s decisions, to the same extent as if you’d made the choice yourself while competent.⁴ A provider or facility with a religious or moral objection cannot simply refuse; the statute requires arranging a transfer to a willing provider.

What Happens Without One

If you lose capacity without a directive, Mississippi Code Section 41-41-211 lets a surrogate make healthcare decisions for you when no agent or guardian has been appointed, or when the appointed agent or guardian cannot reasonably be reached.⁵ The surrogate has to guess at your wishes, and family disagreements can delay decisions or land in court. Even a brief written directive gives providers something concrete to follow and takes that weight off the people closest to you.

Two Things Mississippi’s Law Does Not Do

Some states suspend a living will automatically during pregnancy. Mississippi’s statute contains no pregnancy exception, so your directive applies regardless of pregnancy status.

If you signed an advance directive in another state before moving here, Mississippi recognizes it as long as it complies with the law of the state where it was signed or with Mississippi’s requirements. Having a Mississippi attorney glance at it is a practical safeguard, but you don’t have to redo it from scratch just because you crossed a state line.

What It Costs

The statutory form is free to download, and executing it costs no more than a notary fee or the time of two willing witnesses. An attorney who drafts a customized living will and healthcare power of attorney together typically charges from a few hundred to a couple of thousand dollars depending on complexity. For most people the harder work isn’t the paperwork or the price. It’s sitting down to decide what treatments you would and wouldn’t want, and then talking those decisions through with the person you’re asking to carry them out.
