Advance Directives for Dementia in Maine: Healthcare POA and Living Wills

There is a window — after a dementia diagnosis but before cognitive decline strips legal capacity — when your parent can still put their wishes on paper. Once that window closes, the decisions shift from what your parent wants to what a court-appointed guardian decides.

This is not abstract. In Maine, a durable power of attorney can only be executed while the principal possesses contractual capacity under the Maine Uniform Power of Attorney Act. A physician's certification that your parent lacks the cognitive ability to understand and sign legal documents locks the door permanently.

The Two Documents Every Maine Family Needs

Advance Health Care Directive — This combines two functions into a single document. The "living will" portion records your parent's treatment preferences: whether they want CPR, mechanical ventilation, artificial nutrition, dialysis, or aggressive medical intervention in various scenarios. The "healthcare power of attorney" portion designates an agent — usually an adult child or trusted family member — authorized to make medical decisions when the parent cannot.

Under Maine law, the healthcare agent has broad authority including consenting to or refusing treatment, selecting healthcare providers, accessing medical records, and making end-of-life decisions consistent with the parent's expressed wishes.

Durable Financial Power of Attorney — A separate document authorizing an agent to manage financial affairs: paying bills, accessing bank accounts, filing tax returns, managing investments, filing MaineCare applications, and handling real estate transactions. The word "durable" means the authority survives the principal's subsequent incapacity — without it, the POA becomes void precisely when it is needed most.

Both documents require the parent to have cognitive capacity at the time of signing. Two witnesses must be present, and notarization is strongly recommended (required for real estate transactions under the financial POA).

What Happens Without Advance Directives

If your parent loses capacity without these documents in place, the family must petition the County Probate Court for guardianship (medical and personal decisions) and/or conservatorship (financial management) under Title 18-C, Article 5 of the Maine Uniform Probate Code.

This process is:

• Formal and public — the petition is filed with the court, and notice must be sent to all immediate relatives
• Adversarial — any family member can object, turning a protective filing into a contested hearing
• Expensive — filing fees start at $90 for guardianship or $115 for a joined guardianship/conservatorship petition, plus a mandatory $10 court surcharge, plus court-appointed visitor fees ($150-$200 in Cumberland County, $30/hour in Washington County), plus attorney fees if the petition is contested
• Slow — 60 to 90 days under normal court schedules, though emergency temporary guardianship can be petitioned in cases of immediate safety risk

The court appoints an independent Visitor to interview the parent, evaluate their living conditions, and submit a report. Under confidentiality rules effective January 2026 (18-C M.R.S. § 5-308), clinical evaluations and financial inventories are sealed from public inspection, but the existence of the proceeding and the final order of appointment remain public record.

POLST: The Clinical Companion

A POLST (Provider Orders for Life-Sustaining Treatment) is different from an advance directive — it is a physician-signed medical order, not a legal document. A POLST translates the patient's wishes into actionable clinical instructions that follow them across care settings: from home to ambulance to emergency room to nursing facility.

A POLST addresses specific scenarios:

• CPR: attempt resuscitation or do not resuscitate (DNR)
• Medical interventions: full treatment, selective treatment (IV fluids and cardiac monitoring but no intubation), or comfort-focused treatment only
• Artificial nutrition: long-term feeding tube, trial period, or no artificial nutrition

For dementia patients, the POLST is particularly valuable because it travels with the patient. Paramedics responding to a 911 call check for a POLST form — they do not have time to locate and interpret an advance directive stored in an attorney's filing cabinet.

In Maine, a POLST can be completed by the patient (if competent), by the healthcare agent named in the advance directive, or by a court-appointed guardian. The form must be signed by a physician, nurse practitioner, or physician assistant.

Timing: Act at Diagnosis, Not at Crisis

The most common mistake is delay. Families hear the dementia diagnosis, spend months processing the emotional weight, and by the time they contact an attorney the parent's capacity has deteriorated to the point where they cannot execute the documents.

A physician's capacity evaluation for purposes of signing legal documents is not the same as a clinical dementia assessment. A parent with mild cognitive impairment may be fully capable of understanding and signing a POA — the standard is whether they comprehend the nature and consequences of the document, not whether they can recall what they had for breakfast.

Contact an elder law attorney within 30 days of a dementia diagnosis. The cost of drafting both documents is typically $500 to $1,500 — a fraction of the $5,000 to $15,000 a contested guardianship proceeding would cost.

Don't Use Generic Online Forms

Legal Services for Maine Elders specifically warns against pre-printed online power of attorney forms. Maine has specific statutory requirements for durable powers of attorney, and a generic form downloaded from the internet may not comply with state law — making it unenforceable at the moment it matters most.
