Power of Attorney vs Healthcare Proxy in Massachusetts
POA handles money. Healthcare proxy handles medicine. Massachusetts treats them as separate documents under separate statutes. Most adults in Boston, Lowell, Cambridge, Andover and Worcester need both.
Massachusetts is one of the few states that splits financial and healthcare authority into two distinct documents. Most other states combine them. Massachusetts wants you to think about each separately. Here is how to choose, execute and use each correctly.

Why You Need Both
Each covers different decisions. Without both, your family faces gaps. POA only means doctors cannot get clear consent. Healthcare proxy only means bills go unpaid. Both means full coverage.
Choosing Agents
Many Massachusetts families name the same person (typically spouse) for both. Others split: adult-child financial agent and spouse healthcare proxy. Pick people who can work together if you split.
Execution
POA: principal signature, two adult witnesses (not the agent or related), notary acknowledgment. All four sign together. Healthcare proxy: principal signature, two adult witnesses (not the named proxy). Notary recommended.
