What happens to your medical care and your finances if you are in a car accident tomorrow and cannot speak for yourself? Most people push this question aside, but the honest answer is that without the right legal documents in place, someone else – possibly a court – will make those decisions for you.
At Cote Law Group, PLLC, we work with families throughout Plymouth County every day on exactly this issue. Two documents rise to the top of nearly every conversation: the health care proxy and the power of attorney. They sound similar and are often confused, but they do very different things. Knowing the difference could change everything for your family.
What Is a Health Care Proxy in Massachusetts?
A Massachusetts health care proxy is a legal document that gives another person, called your health care agent, the authority to make medical decisions on your behalf when you cannot make them yourself. The law governing this document is Massachusetts General Laws, Chapter 201D. Under M.G.L. c. 201D, Section 2, any competent adult aged 18 or older can appoint a health care agent by signing a written document in the presence of two adult witnesses.
Your health care agent steps in only when a physician determines in writing that you lack the ability to make or communicate health care decisions. Once triggered, your agent can make any health care decision you could have made yourself, including decisions about life-sustaining treatment, under M.G.L. c. 201D, Section 5. Until that point, you remain fully in control of your own medical choices.
Under M.G.L. c. 201D, Section 3, you generally cannot appoint an administrator, operator, or employee of a health care facility as your agent if you are already a patient or resident there, unless that person is a blood relative, spouse, or adoptive relation. The witnesses must also affirm in writing that you appeared to be of sound mind and free from undue influence. The person you name as your agent cannot serve as one of your witnesses.
What Is a Power of Attorney in Massachusetts?
A power of attorney in Massachusetts is a written document in which you (the principal) authorize another person, called your attorney-in-fact or agent, to manage your financial and legal affairs. It covers matters such as banking, paying bills, managing real estate, filing taxes, and handling business matters. The governing law is M.G.L. c. 190B, Article V (Uniform Power of Attorney provisions).
Massachusetts recognizes several forms of powers of attorney:
- Immediate durable power of attorney — Takes effect when signed and remains effective even if you later become incapacitated.
- Springing durable power of attorney — Becomes effective upon a specified condition, typically incapacity.
- Limited power of attorney — Grants authority for a specific transaction or time period and typically ends once that purpose is completed.
In Massachusetts, a power of attorney is generally durable unless the document states otherwise. A durable power of attorney remains effective during incapacity, which is why it is commonly used in estate planning.
Health Care Proxy vs. Power of Attorney: What Is the Real Difference?
This is the question we hear most often from clients when they call a healthcare proxy attorney in Marshfield, MA. The simplest way to put it is this: a health care proxy governs your body, and a power of attorney governs your finances.
Here is a side-by-side look at how these documents differ:
| Feature | Health Care Proxy | Power of Attorney |
| Governing law | M.G.L. c. 201D | M.G.L. c. 190B, §§ 5-501 through 5-507 |
| Scope | Medical decisions only | Financial and legal matters only |
| When it activates | When physician certifies incapacity | Immediately or upon stated condition |
| Agent title | Health care agent | Attorney-in-fact |
| Covers finances? | No | Yes |
| Covers medical care? | Yes | No |
A common misconception is that a power of attorney covers medical decisions. In Massachusetts, it does not. Even if you grant your spouse a broad durable power of attorney over your finances, that document gives them no authority to speak with your doctors or consent to a surgical procedure. Without a health care proxy, a family member who wants to make those medical decisions may be forced to go to court to obtain guardianship – a process that is slow, expensive, and emotionally draining for everyone involved.
The flip side is equally true. A health care proxy does not give your agent any power over your bank accounts, mortgage, or investments. You need both documents working together.
Who Makes Medical Decisions If I’m Incapacitated and Have No Health Care Proxy?
This is a question that does not have a comfortable answer. Massachusetts does not have a formal default surrogate decision-making statute that clearly ranks who can make medical decisions for an incapacitated adult in the way some other states do. Hospitals and physicians often follow informal family hierarchy in practice, but there is no guarantee that the person you would have chosen will actually be recognized or that family members will agree on a course of treatment.
When disputes arise, the matter can end up before a Probate and Family Court judge, who may appoint a guardian to make decisions on your behalf. That guardian may or may not be the person you would have selected. Completing a health care proxy is the only reliable way to make sure your preferred person has the legal authority to speak for you, and that your known wishes guide the decisions being made.
What Should Be in a Massachusetts Health Care Proxy Form?
Under M.G.L. c. 201D, § 4, a valid health care proxy must identify both you (the principal) and your chosen health care agent. It must also make clear that you intend for the agent to have authority to make health care decisions on your behalf.
Beyond the minimum legal requirements, a well-drafted proxy can include:
- The name and contact information of an alternate agent in case your first choice is unable to serve.
- Any specific instructions about your values, religious beliefs, or treatment preferences.
- Clear guidance on end-of-life decisions, including your wishes regarding life-sustaining treatment.
- Instructions about organ donation.
Working with an estate planning lawyer ensures that your proxy reflects your actual wishes in language that medical providers can act on without confusion.
Do I Need Both Documents?
Yes. A health care proxy and a durable power of attorney cover completely separate areas of your life. Together, they form the foundation of any solid incapacity plan. Without both, there will almost certainly be gaps in coverage when your family needs to act quickly and clearly on your behalf.
At Cote Law Group, PLLC, we typically help clients prepare these documents alongside a will and, in many cases, a revocable living trust. Thinking about these documents together, rather than in isolation, is what makes a real plan rather than a collection of forms.
Key Takeaways
- A health care proxy (governed by M.G.L. c. 201D) gives a trusted person the authority to make medical decisions when you cannot make them yourself.
- A durable power of attorney (governed by M.G.L. c. 190B, §§ 5-501 through 5-507) gives a trusted person the authority to manage your finances and legal matters during incapacity.
- These documents serve completely different purposes. You need both.
- In Massachusetts, a power of attorney does not cover medical decisions, and a health care proxy does not cover financial matters.
- Without a health care proxy, there is no guaranteed process for who makes medical decisions if you are incapacitated – the matter could go to court.
- A healthcare proxy form must be signed in front of two adult witnesses who are not named as your agent.
- Both documents should be tailored to your specific situation with the help of a qualified attorney.
Frequently Asked Questions
Does a power of attorney cover medical decisions in Massachusetts? No. In Massachusetts, a general or durable power of attorney applies only to financial and legal matters. To authorize someone to make medical decisions on your behalf, you must sign a separate health care proxy under M.G.L. c. 201D.
Can I name the same person as both my health care agent and my attorney-in-fact? Yes. Many people choose one trusted individual for both roles. What matters is that the right documents are in place and properly signed.
What happens to my health care proxy if I later regain capacity? Under M.G.L. c. 201D, § 6, if you regain the ability to make health care decisions, authority automatically returns to you. Your agent’s authority is suspended while you have capacity.
Can I revoke my health care proxy? Yes. Under M.G.L. c. 201D, § 7, you can revoke a health care proxy at any time, either orally, in writing, or by any act that clearly shows your intent to revoke it, as long as you have capacity to do so.
Does Massachusetts recognize a medical power of attorney from another state? Under M.G.L. c. 201D, § 11, a health care proxy or similar instrument executed in another state in compliance with that state’s law is generally enforceable in Massachusetts, with limited exceptions related to health care facility policies.
Do I need an attorney to complete a healthcare proxy form in Massachusetts? The law does not require you to use an attorney, but the document must meet specific legal requirements to be valid. An attorney can also help you include detailed guidance about your values and wishes that a bare-bones form does not capture.
