Maine Power of Attorney Requirements (2026)

Updated August 3, 2026. Quick answer: Must be signed by the principal (or, in the principal’s conscious presence, by another individual directed by the principal) and acknowledged before a notary public or other individual authorized to take acknowledgments; the Act states no witness requirement. This state has no statutory form. A power of attorney here is durable by default — it survives incapacity unless it says otherwise.

What decides whether the document is valid

Must be signed by the principal (or, in the principal’s conscious presence, by another individual directed by the principal) and acknowledged before a notary public or other individual authorized to take acknowledgments; the Act states no witness requirement. Get this wrong and the document is not merely weak — it may be void, and you will find out at the moment somebody needs to use it.

Who may not witness: n/a — the Act requires notarial acknowledgment only; it does not require or address witnesses. Where a state does bar particular people from witnessing, this is the condition that most often fails in practice, because the people in the room are usually the people with an interest.

There is no statutory form

Maine does not put a form in its statute, so there is nothing official to copy. The requirements above still govern whatever document you use.

Durability — the point most people get wrong

Here a power of attorney is durable by default: it keeps working after the principal loses capacity unless the document says it should not. That is the opposite of the historical rule and it is why old advice about needing magic words can mislead.

Why a springing power often fails when it is needed, and why durable is usually the better default.

If a bank refuses it

Maine addresses this by statute: 18-C M.R.S. §5-920: a person must accept an acknowledged POA, or request certification/translation/opinion of counsel, no later than 7 business days after presentation; if requested, acceptance is due no later than 5 business days after receipt. Wrongful refusal exposes the refuser to a court order mandating acceptance and liability for attorney’s fees and costs. Six statutory exceptions excuse refusal (e.g., good-faith doubt about validity, suspected abuse, federal-law conflict).

What the acceptance-and-refusal statutes require where they exist, the permitted grounds for refusal, and the attorney-fee remedy.

What the form does not solve

• Social Security will not accept it. No power of attorney works there — a representative-payee application is the only route.
• It has to be signed while capacity is intact. The day that closes, the alternative is a court.
• Name a successor agent. A document whose only named agent has died or declined does nothing — how to choose when there is no obvious person.
