Massachusetts Power of Attorney Requirements
Massachusetts’ durable Power of Attorney law is in the Uniform Probate Code, M.G.L. chapter 190B, §§ 5-501 to 5-507. It is short: it explains what makes a Power of Attorney durable and how third parties may rely on it. Here are the essentials in plain English, each linked to the official General Laws.
Based on Massachusetts General Laws, chapter 190B, §§ 5-501 to 5-507. Reviewed October 2026. Education, not legal advice — Massachusetts’s requirements are set by state law and can change, so confirm them with an official Massachusetts source or a licensed attorney.

Where is Massachusetts’ Power of Attorney law?
Massachusetts’ durable Power of Attorney law is M.G.L. chapter 190B, §§ 5-501 to 5-507. Massachusetts does not publish an official statutory Power of Attorney form, so many people have an attorney prepare the document.
Is a Massachusetts Power of Attorney durable?
Only if it says so. Under M.G.L. c. 190B, § 5-501, a Power of Attorney is durable when it is in writing and contains words such as “This power of attorney shall not be affected by subsequent disability or incapacity of the principal, or lapse of time,” or similar words. A Power of Attorney can also be written to take effect upon the principal’s disability or incapacity.
Does a Massachusetts Power of Attorney have to be notarized?
The durable Power of Attorney statute (§ 5-501) requires a writing with durability language; it does not itself list notarization or witnesses. In practice, a bank, registry of deeds or other institution may ask for a notarized document, so confirm what will be needed with a Massachusetts attorney before signing.
Who is a Massachusetts agent accountable to?
Under M.G.L. c. 190B, § 5-503, if a court later appoints a conservator or other fiduciary for the principal’s property, the agent (called the attorney in fact) is accountable to that fiduciary as well as to the principal. Keeping clear records protects both the principal and you.
Can a bank rely on a Massachusetts Power of Attorney?
Under M.G.L. c. 190B, § 5-507, a third party acting in good faith reliance on a durable Power of Attorney is not held liable. Under § 5-505, the agent may sign an affidavit that they have no knowledge of a revocation or of the principal’s death, which can be relied on.
How is a Massachusetts Health Care Proxy signed?
Healthcare decisions are covered separately by a Health Care Proxy under M.G.L. chapter 201D. Under § 2, it is signed in writing in the presence of two other adults, who also sign. The person named as health care agent cannot be a witness. Massachusetts does not publish an official state proxy form; the Massachusetts Trial Court Law Libraries list sample forms.

The universal rules of the role
The exact forms, witnessing, and notarization rules change from state to state — those are in Massachusetts’s essentials above.But the heart of the role is the same everywhere in the U.S. Here’s what always applies.
Your duties as an agent
Every decision is for the principal, never for you. This is the core legal duty of an agent, everywhere.
Never mix the principal’s funds with your own. Use their accounts for their expenses, and don’t borrow or lend to yourself.
Track every transaction, receipt, and major decision. Good records protect the principal — and protect you if anyone ever asks.
You can only do what the Power of Attorney actually authorizes. If it isn’t granted in the document, you don’t have the authority.
Follow what they’d want, preserve their existing estate plan where you can, and avoid anything that benefits you at their expense.
What a Power of Attorney can’t do
A Power of Attorney works only while the principal is alive. The moment they pass, it ends and the will and executor (or trustee) take over.
An agent cannot make or rewrite the principal’s will, and generally can’t change beneficiary designations unless the document specifically allows it.
Powers not written into the document — like making gifts or changing accounts — usually aren’t allowed. When in doubt, it’s probably not authorized.
When you sign correctly as the agent (not personally), you’re acting for them — you don’t take on their debts by serving.
How to sign as an agent
Always sign in your representative capacity — never just your own name on the principal’s business. A safe format anywhere is “Jane Doe, as agent for John Doe” (some institutions prefer “John Doe by Jane Doe, agent”). Signing your name alone can make you personally liable; signing as the agent makes clear you’re acting for them.
When the authority ends
- The principal revokes it — they can, at any time, as long as they’re competent.
- The principal dies — authority passes to the will or trust.
- A court appoints a guardian or conservator, or the document’s own end date or condition is reached.
One key distinction, everywhere: a durable Power of Attorney keeps working if the principal becomes incapacitated; a non-durable one ends at incapacity. Whether yours is durable is stated in the document itself.
