Maine Living Will Requirements: What Makes Your Document Legally Valid

Maine Does Not Use a Standalone Living Will

Most people searching for a "Maine living will" expect a separate document they can fill out and sign. That document does not exist under current Maine law.

Instead, Maine combines your living will with your healthcare agent designation into a single legal instrument called an advance health care directive, governed by the Uniform Health Care Decisions Act (Title 18-C, Section 5-801 et seq.). Your treatment preferences — what most people think of as a "living will" — appear in Part 2 of this combined document, labeled "Individual Instructions."

This matters because filling out only a treatment-preference form downloaded from a generic website may not meet Maine's execution requirements. The state expects a unified document with specific signing formalities.

The Four Legal Requirements for a Valid Maine Living Will

1. You Must Have Capacity When You Sign

Maine law defines capacity as the functional ability to understand your diagnosed condition, evaluate the risks and benefits of proposed treatments, comprehend the consequences of refusing treatment, and communicate a healthcare decision.

There is no required cognitive test. Your primary care physician makes this determination. But if you are signing while managing early-stage dementia or another progressive condition, having your physician document your capacity at the time of signing creates a stronger legal foundation.

2. The Document Must Be in Writing and Signed by Hand

Maine explicitly prohibits electronic or digital signatures on healthcare powers of attorney, regardless of any other state law validating digital signatures (18-C M.R.S. Section 5-803(2)). You must physically sign the document with a pen.

3. Two Adult Witnesses Must Sign in Your Presence

Both witnesses must be competent adults (18 or older) who sign the document in your physical presence. You and both witnesses must all be in the same room at the same time.

Who cannot witness:

• Your designated healthcare agent or alternate agent
• Owners, operators, or employees of a long-term care facility where you receive care (unless related to you by blood, marriage, or adoption)

Best practice: choose witnesses who are not family members, heirs, or anyone who could benefit from your estate. While the statute does not explicitly ban relatives as witnesses, using disinterested witnesses prevents potential challenges.

4. Notarization Is Optional — With One Critical Exception

A notary is not required to make your living will legally valid in Maine. However, notarization is highly recommended if:

• You spend part of the year in another state (many southern states require notarized documents)
• You want to grant your healthcare agent authority over burial or cremation decisions — under 22 M.R.S. Section 2843-A, this specific grant requires notarization

When Your Living Will Takes Effect

Your individual instructions do not activate the moment you sign them. Under Maine law, the directive becomes operative only when your primary physician formally determines that you lack the capacity to make your own healthcare decisions.

You can include a provision making the agent's authority effective immediately, but this is optional. Without that provision, the default trigger is a physician's incapacity determination.

What to Include in Your Individual Instructions

Maine's statutory form allows you to address:

• Whether you want life-sustaining treatment if you are terminally ill or permanently unconscious
• Preferences for artificial nutrition and hydration (feeding tubes, IV fluids)
• Pain management priorities, including comfort-focused care
• Preferences for specific medical interventions (ventilators, dialysis, blood transfusions)
• Organ and tissue donation preferences
• Burial or cremation preferences (if notarized)
• Psychiatric treatment preferences for individuals with fluctuating mental health conditions

The more specific your instructions, the clearer the guidance for your healthcare agent and medical team.

How a Living Will Interacts with Other Maine Documents

Your advance directive works alongside — but does not replace — two other critical documents:

POLST form: A Provider Orders for Life-Sustaining Treatment is a medical order signed by your physician. Unlike your living will, a POLST is directly actionable by emergency responders. If paramedics arrive and find only your advance directive, they are legally required to perform full resuscitation.

Financial power of attorney: A separate document under different statutory requirements (must be notarized). Your healthcare directive covers medical decisions only, not financial ones.

Next Steps

Getting your Maine living will right means understanding that it is one part of a combined advance health care directive with specific signing ceremonies. The Maine Advance Directive & Living Will Kit walks you through each section of the statutory form, the witness requirements, and the filing process to make sure your document holds up when it matters.
