Maine Advance Healthcare Directive: How to Set One Up for an Adult Child with a Disability

The call comes on a Saturday morning. Your 19-year-old is in the emergency room after a seizure, and the nurse at the front desk tells you they cannot share any medical information or let you into the consultation. Your child has a significant intellectual disability. They cannot describe their medication regimen, explain their seizure history, or consent to a CT scan. But under federal law, they are a legal adult — and you have no documented authority to act on their behalf.

This scenario plays out across Maine every year because families miss a critical step at the 18th birthday: executing an Advance Health Care Directive.

What Maine's Advance Health Care Directive Actually Is

Maine's Uniform Health Care Decisions Act (Title 18-C, §§ 5-801 to 5-817) combines two functions into a single document. It lets your adult child both state treatment preferences (traditionally called a living will) and designate a healthcare agent — a person authorized to make medical decisions if the individual loses capacity.

For families of young adults with disabilities, the healthcare agent designation is the critical piece. It gives you documented legal authority to access medical records, discuss treatment options with providers, consent to procedures, and make emergency decisions — all without court involvement.

The Capacity Standard for Signing

Your adult child must possess the capacity to understand the basic nature and consequences of a proposed medical treatment, including benefits, risks, and alternatives, and the ability to make and communicate a choice. Under 18-C § 5-802, this is the standard for healthcare decision-making capacity.

This threshold is lower than most parents expect. A young adult who can understand "this person will help me make medical decisions when I can't" and communicate agreement — verbally, through sign language, through an AAC device, or through gestures — generally meets the standard.

If your child's cognitive limitations are so severe that they cannot meet even this threshold, the Advance Health Care Directive is not the right tool. Explore Maine's default-surrogate process and, if that does not provide enough authority, a guardianship or protective arrangement through the probate court.

Execution Rules That Cannot Be Skipped

Maine imposes strict requirements under 18-C § 5-803, and getting any of them wrong invalidates the document:

Two in-person witnesses are mandatory. Both witnesses must be physically present when your adult child signs the document. Electronic or digital witness signatures are explicitly invalid. The witnesses should be people who have no financial or caregiving interest in your child's medical decisions.

Notarization may be added but cannot substitute for witnesses. Some families assume that notarization alone is sufficient because that's how financial Powers of Attorney work in Maine. It is not. The two-witness requirement is non-negotiable for healthcare directives.

The document must be in writing and signed by your adult child (the "principal"). If your child cannot physically sign, Maine allows another person to sign in the principal's conscious presence at their direction.

When the Agent's Authority Activates

Unless the document states otherwise, the healthcare agent's authority kicks in only when the primary physician formally determines that your adult child lacks capacity to make a specific medical decision. If your child regains capacity — after recovering from anesthesia, for example — the agent's authority immediately ceases and your child's direct consent is required again.

This design preserves autonomy. Your child keeps their medical decision-making rights during periods of capacity, and you step in only when they genuinely cannot participate.

How It Prevents the HIPAA Lockout

The practical value of an executed Advance Health Care Directive is that it creates documented proof of your legal standing. When you arrive at an emergency room, urgent care, or specialist's office, you present the directive. HIPAA's privacy rules allow disclosure of protected health information to a personal representative — and a designated healthcare agent under state law qualifies.

Without this document, providers may need to rely on your adult child's consent, a designated healthcare agent or guardian, or Maine's default-surrogate process. A default surrogate may need a physician incapacity determination, and that fallback does not by itself solve routine records access.

Pairing the Directive with HIPAA Release Forms

The Advance Health Care Directive covers decision-making authority. But for routine records access — reviewing lab results, getting copies of therapy notes, communicating with specialists between appointments — a signed HIPAA authorization form is simpler and more broadly accepted.

Have your adult child sign both: the Advance Health Care Directive for decision-making authority during incapacity, and a standing HIPAA release naming you as an authorized recipient of all medical information. The release is revocable at any time and requires minimal capacity to execute.

What If the Default Surrogacy Rules Apply

If an adult lacks capacity and has no designated agent or court-appointed guardian, Maine law permits a reasonably available surrogate to make health-care decisions after the primary physician determines incapacity. The priority list starts with a spouse, then an adult with a spouse-like relationship, adult children, parents, and adult siblings, followed by other listed relatives and, in some circumstances, an adult who has shown special concern.

For an unmarried young adult with no adult children and no spouse-like partner, a parent may be next in priority, subject to the statutory rules and availability. This default process does not by itself solve the records-access problem: providers may still require a HIPAA authorization before discussing care with parents.

An executed Advance Health Care Directive eliminates the guesswork.

The Complete Setup Process

The Maine Adult Guardianship & Alternatives Guide includes step-by-step instructions for executing an Advance Health Care Directive that meets Maine's statutory requirements — including how to pair it with HIPAA and FERPA releases, how to assess whether your child has sufficient capacity to sign, and what to do if they don't. The guide also covers how the directive interacts with Supported Decision-Making agreements and educational Powers of Attorney to create a complete out-of-court protection framework.
