Living Will and Advance Health-Care Instruction Requirements in Massachusetts

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.

At a glance

Governing law and documentNo 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 instructionState guidance treats a personal directive as evidence of wishes; every competent adult may appoint a health care agent through a proxy (§ 2)
Oral, written, and signature formNo 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 disqualificationsNo 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 triggerNo 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 comfortA 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 limitsChapter 201D gives a proxy agent authority over life-sustaining treatment, subject to express proxy limits (§ 5); state guidance treats a separate personal directive as evidence of wishes
Revocation, notice, and registryNo 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 effectDoctors 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. State law-library guidance says a separate personal directive gives evidence of wishes but is not legally binding on doctors.

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.

This page is general legal information about state-law living-will and future treatment-instruction requirements, not medical advice or legal advice about a particular diagnosis, pregnancy, treatment, facility, clinician, surrogate, or decision. A formally valid instruction may operate only after specific medical and capacity findings, may be subject to provider-transfer procedures and other statutory limits, and does not guarantee a particular treatment outcome. Agent appointments, clinician orders, psychiatric directives, directives for minors, and organ donation follow different rules. Verified against the cited official statutes on the date shown; confirm current law and obtain licensed legal and medical advice before signing, revoking, or relying on an instruction.
