At a glance
| Governing law | Maine Uniform Power of Attorney Act, 18-C M.R.S. Art. 5, Part 9, §§ 5-901 to 5-964 (UPOAA-based, enacted 2017) |
|---|---|
| Who must sign | Principal, or in the principal's conscious presence by another individual directed by the principal to sign the principal's name (§ 5-905(1)) |
| Notarization | Mandatory for validity, not merely a presumption aid: 'not valid unless it is acknowledged before a notary public or other individual authorized by law to take acknowledgments' (§ 5-905(1)) |
| Witnesses | None required by the Act |
| Statutory form | § 5-951 offers an optional agent certification form for facts about an existing power; the section is not a grant form |
| Durable by default? | Yes. Durable unless the document 'expressly provides that it is terminated by the incapacity of the principal' (§ 5-904); a durable POA must also carry mandatory statutory notices to the principal and agent (§ 5-905(2)) |
| Springing POA allowed? | Yes (§ 5-909(1)); the principal may name person(s) to determine in writing that the trigger occurred, or if incapacity and no one is named, a physician or an attorney/judge/government official makes that determination (§ 5-909(2)-(3)) |
| Real estate extras | Written instruments require acknowledgment before deed-registry recording (§ 203); § 353-A expressly includes a real-property conveyancing POA among otherwise valid instruments whose missing consideration or seal is cured |
| Out-of-state POAs | Yes — a POA executed outside Maine is valid if its execution complied with the law of the jurisdiction indicated in the POA (or, if none indicated, the jurisdiction of execution), or with the federal military-POA statute (§ 5-906(4), § 5-907) |
Requirements one by one
Signing, acknowledgment, and notices
The principal may sign personally or direct another individual to sign in the principal's conscious presence. The power is invalid unless acknowledged before a notary or another person authorized to take acknowledgments (18-C M.R.S. § 5-905(1)). Section 5-905(2) also makes a durable power invalid unless it contains notices addressed to the principal and agent substantially in the prescribed form.
Durability and later effectiveness
A power created under the Act is durable unless it expressly says incapacity terminates it (§ 5-904). It normally begins on execution, but the principal may specify a future date or event and name one or more people to record that event in writing (§ 5-909(1)-(2)). For an incapacity trigger without an available named determiner, § 5-909(3) supplies a physician route or, under a different incapacity category, an attorney, judge, or appropriate official.
What trips people up
- A signature's acknowledgment creates a presumption of genuineness, but § 5-905(1) separately requires acknowledgment for validity.
- Section 5-951 offers an optional agent's certification of facts about a power. Its wording concerns an existing power; it is not the instrument by which the principal grants authority.
- Written instruments generally require acknowledgment before recording in a deed registry (33 M.R.S. § 203). Section 353-A(1) expressly includes a power of attorney for conveying real property among otherwise valid instruments that remain valid despite missing stated consideration or a grantor's seal.
Common questions
Can someone else sign for me? Yes, if directed to sign your name in your conscious presence (§ 5-905(1)).
Will a power signed elsewhere work in Maine? Section 5-906(4) recognizes one executed under the law governing its meaning and effect or under 10 U.S.C. § 1044b for military powers. Under § 5-907, the governing jurisdiction is the one indicated in the power or, if none is indicated, where it was executed.
