Massachusetts: Living Will and Advance Health-Care Instruction Requirements
The short answer
Massachusetts has no statute making a standalone personal directive or living will legally binding on doctors. A person may write one as evidence of treatment wishes, but the statutory route for binding substitute decisions is a health care proxy naming an agent. The proxy—not the personal directive—uses a written, signed, two-witness execution rule and becomes operative after a written incapacity finding.

This is the general rule in Massachusetts. Ezel applies current Massachusetts law to your specific facts and answers with citations to the statutes.
| Governing law and document | No binding standalone living-will statute. The Massachusetts Trial Court Law Libraries says a personal directive or living will is not legally binding but gives providers evidence of wishes. Mass. Gen. Laws ch. 201D instead governs an agent-based health care proxy |
|---|---|
| Who may make an instruction | No statutory maker-eligibility rule for a nonbinding personal directive. The separate binding proxy route is available to every competent adult (§ 2) |
| Oral, written, and signature form | No statutory living-will writing, signature, date, oral, directed-signature, or electronic-execution formula. A ch. 201D proxy is written and signed by the adult or at the adult's direction in two witnesses' presence (§ 2) |
| Witness, notary, and disqualifications | No statutory witness or notary rule makes a personal directive binding. The separate proxy requires two adult witnesses, bars the named agent from witnessing, and provides no notary substitute (§ 2) |
| Covered conditions and trigger | No statutory medical-condition or incapacity trigger makes a standalone living will controlling. Proxy authority begins after the attending physician makes and records a written incapacity determination (§ 6) |
| Treatment, nutrition, hydration, and comfort | A personal directive may give evidence of treatment wishes but does not itself bind doctors. A proxy agent may make any health-care decision the adult could make, including life-sustaining-treatment decisions, subject to express proxy limits (§ 5) |
| Pregnancy and other statutory limits | No standalone living-will statute supplies a document-specific pregnancy, nutrition/hydration, assisted-suicide, or mercy-killing rule. Chapter 201D regulates decisions made through a health care proxy |
| Revocation, notice, and registry | No statutory revocation, provider-notice, charting, or registry procedure applies to a personal directive. Section 7's oral, written, intent-act, later-proxy, and spouse-divorce rules revoke a health care proxy, not a standalone living will |
| Provider duties, recognition, and effect | Doctors are not legally bound by a personal directive or living will, though it provides evidence of wishes. Providers must comply with a health care agent's decisions under a valid proxy (§ 5); ch. 201D states no comparable living-will compliance or interstate rule |

Massachusetts does not have a statute that makes a standalone personal directive
or living will legally binding on doctors. A person may still write treatment
wishes. The current Massachusetts Trial Court Law Libraries guidance says the
document gives care providers clear evidence of those wishes, but it does not
itself compel treatment decisions.
Without a binding living-will statute
The statutory route for binding substitute decisions is a health care proxy under
chapter 201D. That document appoints an agent. It must be written and signed by the
adult, or at the adult's direction, in front of two adult witnesses. The agent
cannot be a witness.
The proxy agent begins acting only after the attending physician makes a written
incapacity determination and enters it in the medical record. Once authorized,
the agent may make the decisions the adult could make, including decisions about
life-sustaining treatment, subject to limits written into the proxy. Providers
must comply with those agent decisions. Those execution, activation, revocation,
and compliance rules belong to the proxy; they do not convert a separate personal
directive into a binding living will.
What trips people up
- Two witnesses validate the proxy, not the personal directive as a binding
living will. Chapter 201D's ceremony attaches to appointment of an agent. - Writing specific treatment choices still has practical value. The official
state guidance describes the document as evidence of what the person wants and
does not want, even though doctors are not legally bound by it. - Pending S 869 would not create a binding living-will form. It would add
anti-discrimination rules concerning whether a person has an advance directive
or treatment instruction.
Common questions
Can I still write down treatment wishes?
Yes. The state law-library guidance says a personal directive gives providers
clear evidence of wishes. It also says the document is not legally binding on
doctors.
Do two witnesses make my personal directive binding?
No. Section 2's two-witness rule governs a health care proxy that appoints an
agent. Massachusetts does not apply that statute as a binding living-will
execution formula.
What Massachusetts document gives someone authority to decide for me?
A health care proxy under chapter 201D. It names an agent whose authority begins
after the written incapacity finding required by § 6.
