Durable power of attorney

A power of attorney lets you name an agent to handle your financial affairs: paying bills, managing accounts, dealing with insurance, and signing on your behalf. Durable means it continues if you become incapacitated, which is exactly when it is needed.

Health care proxy

Massachusetts uses a health care proxy, under General Laws chapter 201D, to name a health care agent. Your agent makes medical decisions only when your attending physician determines that you cannot make or communicate them yourself, and is expected to follow your wishes as best they know them.

A HIPAA authorization is a companion document that lets the people you choose receive your medical information, so they can stay informed and help.

Writing down your wishes

Massachusetts does not have a living will statute, but you can still write down your wishes about end of life care to guide your agent. For people with serious illness, a clinician can complete a MOLST form, a medical order that travels with the patient.

If there are no documents

If you cannot act and have not named agents, your family may need to petition the Probate and Family Court for a conservator to manage money or a guardian to make personal and medical decisions. That process takes time and is public.

Choosing your agents

Choose people you trust who can act calmly and are reachable when needed. Name a backup for each role, and tell the people you choose where your documents are.

Common questions

Can my spouse automatically make decisions for me?

Not for everything. Naming your spouse as your agent is how you make that authority clear.

When does a power of attorney stop working?

It ends at death. After that, the personal representative or successor trustee takes over.
