Massachusetts power of attorney

State form

• Under Massachusetts General Laws chapter 190B, section 5-501, a power of attorney is durable when it says, for example, “This power of attorney shall not be affected by subsequent disability or incapacity of the principal, or lapse of time,” or uses similar words.³
• Massachusetts law also allows a springing durable power with the words “This power of attorney shall become effective upon the disability or incapacity of the principal.”³
• The Massachusetts RMV publishes form TTLREG109, the Vehicle Owner’s Limited Power of Attorney, which can only be used for RMV transactions.⁴
• The Massachusetts RMV accepts either its own form TTLREG109 or any free-form power of attorney that meets Massachusetts legal requirements.⁵
• For tax matters, the Massachusetts Department of Revenue generally accepts a power of attorney only on Form M-2848.⁶

Signing

• Under Massachusetts General Laws chapter 183, section 32, the law on acknowledging and recording deeds also applies to a letter of attorney used to convey real estate.¹
• The Massachusetts Land Court requires a power of attorney used to convey registered land to carry an acknowledgment substantially in the form of chapter 222, section 15(b), with satisfactory evidence of identity and a statement that it was signed voluntarily.²
• The Massachusetts Land Court applies that acknowledgment rule whether the power of attorney was notarized in Massachusetts or in another state.²
• The Massachusetts RMV accepts electronic signatures on a power of attorney except when it has a witness signature, in which case every signature must be handwritten.⁵
• On the Massachusetts RMV limited power of attorney form, the principal, the agent and a witness for each owner’s signature all sign by hand.⁵
• An agent signing Massachusetts RMV documents under a power of attorney must write “P.O.A.” next to each signature.⁵

Deadlines

• A Massachusetts durable power of attorney does not lapse with time unless the document states when it ends.⁷
• In Massachusetts, the principal’s death does not cut off an agent who, without actual knowledge of the death, acts in good faith under a written power of attorney.⁸
• The Massachusetts RMV limited power of attorney expires 30 days after it is signed or when the registration or title is processed, whichever comes first.⁴
• The Massachusetts Department of Revenue asks for 2 business days to attach a Form M-2848 to the taxpayer’s account.⁶

Where it is filed

• Under chapter 185, section 110, as quoted by the Massachusetts Land Court, a power of attorney for registered land is acknowledged, filed with the registry district recorder and registered, and so is any revocation.²
• Since February 2, 2026, the Massachusetts Land Court refuses to register a power of attorney whose powers depend on an off-record document or another vague reference.⁹
• A third party in Massachusetts is treated as knowing of a revocation only once it is in a writing signed by the principal or a personal representative and actually received, or, in a real estate transaction, recorded under chapter 184, section 25.⁸
• When a Massachusetts agent signs a recordable document, the agent’s affidavit that the power was still in force can be recorded with it.¹⁰
• A Massachusetts taxpayer does not need to file a power of attorney with the Department of Revenue unless a matter requires contact with DOR employees.⁶

Law

• Acts an agent takes under a Massachusetts durable power of attorney while the principal is incapacitated bind the principal as if the principal were competent.⁷
• If a Massachusetts court later appoints a conservator for the principal’s property, the agent answers to the conservator, who can revoke or amend the power of attorney.¹¹
• A Massachusetts durable power of attorney can nominate a conservator or guardian, and the court follows the most recent nomination unless there is good cause or disqualification.¹¹
• In Massachusetts, the agent’s affidavit that the agent did not know of a revocation, death or incapacity is conclusive proof that the power was still in effect for good-faith acts.¹⁰
• Massachusetts General Laws chapter 190B, section 5-506 lets the agent sue for damages when a third party unreasonably refuses a valid durable power of attorney.¹²
• A third party that relies in good faith on a Massachusetts durable power of attorney is not liable for acting on it.¹³
• The Massachusetts RMV never transfers a vehicle title to the agent named in the power of attorney.⁵
• The Massachusetts RMV stops accepting a power of attorney once it learns the principal has died.⁵
• A Massachusetts health care proxy, the separate document for medical decisions under chapter 201D, is signed in the presence of two adults who sign as witnesses.¹⁴
• The person named as health care agent in a Massachusetts health care proxy cannot act as a witness to it.¹⁴

• Full legal names and addresses of principal and agent
• Which powers the agent gets, and any limits
• When it starts and whether it continues if the principal becomes incapacitated
• A successor agent, if you want one

Health care decisions usually take a separate document (a health care power of attorney or advance directive).
