Maine: Health Care Power of Attorney Requirements
The short answer
A Maine power of attorney for health care must be written and signed in person—not electronically—by an adult or emancipated minor with capacity and by two witnesses. Notarization is not a substitute for the two witnesses.

| Governing law & document | Maine's Uniform Health Care Decisions Act, 18-C M.R.S. art. 5, pt. 8. A power of attorney may stand alone or be combined with individual instructions in an advance health care directive; § 5-805 provides an optional form. |
|---|---|
| Who can sign | An adult or emancipated minor with capacity signs the writing (§ 5-803(2)). Capacity includes understanding the condition, benefits, risks, alternatives, consequences of declining treatment, and the consequences of naming an agent (§ 5-802(3)). |
| Witnesses or notary | Two witnesses are mandatory; the principal's and witnesses' signatures must be made in person, not electronically. There is no notary alternative (§ 5-803(2)). A narrow infectious-disease isolation procedure permits directed signing and real-time audiovisual witnessing within a hospital or residential facility (§ 5-803-A). |
| Who can't witness or serve | Part 8 states no relationship, inheritance, provider, or agent disqualification for the two witnesses. The agent must have capacity and, unless related by blood, marriage, or adoption, cannot be an owner, operator, or employee of the residential long-term-care institution where the principal receives care (§§ 5-802(2), 5-803(2)). |
| When the agent can act | Springing by default: authority starts upon a determination of incapacity and ends upon recovery, unless the power says otherwise. The primary physician or a court ordinarily determines capacity; a qualified mental-health examiner may do so for a directive authorizing mental-health treatment (§ 5-803(3)-(4)). |
| Agent's powers & limits | May make any health-care decision the principal could make, subject to instructions and known wishes; the statutory definition expressly includes DNR orders and providing, withholding, or withdrawing artificial nutrition, hydration, and life-sustaining treatment (§§ 5-802(6), 5-803(2), (5)). Psychiatric admission under a directive has separate conditions and a five-working-day limit (34-B M.R.S. § 3831(6)). |
| How to revoke | A principal with capacity revokes the agent designation only by signed writing or personally informing the supervising provider. A later conflicting directive revokes to the extent of conflict; an annulment/divorce/dissolution/separation decree revokes a spouse-agent unless the decree or power says otherwise (§ 5-804). |
| Out-of-state directives | Valid if it complies with Part 8 regardless of where executed or communicated, or if valid under the law of the state of execution (§ 5-803(8)). |

Maine's Uniform Health Care Decisions Act, 18-C M.R.S. article 5, part 8,
governs the appointment. A power of attorney for health care may stand alone or
appear with treatment instructions in a combined advance health care directive.
Section 5-805 publishes a form, but expressly makes it optional.
Requirements one by one
Governing law and document
The power of attorney is the designation of an agent with capacity to make health
care decisions (§ 5-802(14)). The optional statutory form combines that
appointment with individual instructions, but a different writing may be used
(§ 5-805).
Who can sign
An adult or emancipated minor with capacity may execute the power
(§ 5-803(2)). Capacity includes understanding the diagnosed condition, treatment
benefits, risks and alternatives, the consequences of declining treatment, and
the consequences of naming an agent (§ 5-802(3)). The ordinary rule requires the
principal to sign; Maine provides a narrow directed-signature exception only for
specified facility isolation circumstances (§ 5-803-A).
Witnesses or notary
The writing must be signed by the principal and two witnesses. All three
signatures must be made in person, not electronically (§ 5-803(2)). Maine does
not offer notarization as an alternative, so a notary alone does not satisfy the
two-witness rule.
Section 5-803-A supplies a narrow exception when an infectious disease confines a
principal to an isolation room or ward in a hospital or residential health care
facility. The principal may direct someone elsewhere in that facility to sign,
and real-time two-way audiovisual technology may be used for the direction and
witnessing. The exception does not apply in other settings.
Who cannot witness or serve
Part 8 does not disqualify a witness because the person is related, an heir, the
agent, or connected to a provider. It simply requires two witness signatures,
made in person (§ 5-803(2)); the optional form adds no eligibility attestation
(§ 5-805).
An agent must be an individual with capacity (§ 5-802(2)). Unless related to the
principal by blood, marriage, or adoption, an owner, operator, or employee of the
residential long-term health care institution where the principal receives care
cannot serve (§ 5-803(2)).
When the agent can act
Authority is springing by default: it begins when the principal is determined
to lack capacity and ends upon recovery, unless the power specifies another rule
(§ 5-803(3)). The primary physician or a court ordinarily makes the determination.
A person qualified to conduct the specified mental-health examination may make
it for a directive authorizing mental-health treatment (§ 5-803(4)). The optional
form expressly lets the principal choose immediate authority (§ 5-805).
Powers and limits
The agent may make any health-care decision the principal could make, subject to
the document (§ 5-803(2)). Maine expressly includes selecting institutions,
approving or refusing tests, surgery, medication, and DNR orders, and providing,
withholding, or withdrawing artificial nutrition, hydration, and life-sustaining
treatment (§ 5-802(6)). Known instructions and wishes control; otherwise the
agent uses the principal's best interest and known personal values (§ 5-803(5)).
Part 8 recognizes directives authorizing mental-health treatment, but special
psychiatric-admission rules apply. Admission over the person's present objection
requires express advance authorization, and the informal stay under that rule
may not exceed five working days (34-B M.R.S. § 3831(6)).
How to revoke
The agent designation has a stricter revocation rule than treatment instructions.
A principal with capacity may revoke the agent only through a signed writing
or by personally informing the supervising health care provider (§ 5-804(1)).
Other parts of the directive may be revoked in any manner communicating intent
(§ 5-804(2)).
A later directive revokes an earlier one to the extent of conflict. A decree of
annulment, divorce, dissolution, or legal separation revokes a spouse-agent
unless the decree or power says otherwise (§ 5-804(4)-(5)).
Out-of-state directives
A directive works if it complies with Maine's Part 8 regardless of where it was
executed or communicated, or if it was valid under the law of the state where
executed (§ 5-803(8)).
What trips people up
- A notary does not replace the witnesses. The statute requires the
principal and two witnesses to sign; it states no notary alternative
(§ 5-803(2)). - The ordinary signatures cannot be electronic. Maine expressly requires
in-person signatures. The audiovisual process is confined to the infectious-
disease isolation circumstances in § 5-803-A. - The agent designation cannot be revoked in just any manner. Destruction or
notice only to the agent is not one of § 5-804(1)'s two methods.
Common questions
Can I use a notary instead of witnesses?
No. Maine requires two witnesses and gives no notary substitute (§ 5-803(2)).
Do my witnesses have to be unrelated or disinterested?
Part 8 states no such requirement. The statutory rule requires two in-person,
non-electronic witness signatures (§ 5-803(2)).
Can my agent act immediately?
Yes, if the power says so. Otherwise authority begins only upon the statutory
capacity determination (§ 5-803(3)-(4)).
Will a directive signed elsewhere work in Maine?
Yes, if valid under the law of the state where it was executed (§ 5-803(8)).
