Medical Power of Attorney in Maine: Healthcare vs. Financial POA

Maine Has Two Completely Different Powers of Attorney

One of the most common mistakes in Maine estate planning is conflating a medical power of attorney with a financial power of attorney. They are governed by different statutes, have different signing requirements, and serve entirely different purposes.

Medical power of attorney (officially called a "health care agent" designation under Maine's Uniform Health Care Decisions Act, Title 18-C, Section 5-803): Gives your chosen agent authority to consent to or refuse medical treatment, access your medical records, and make end-of-life decisions on your behalf.

Financial power of attorney (governed by Title 18-B): Gives your agent authority over financial matters — bank accounts, real estate transactions, tax filings, bill payments. Must be notarized to be valid.

You need both, but they do not need to name the same person. Some families designate one adult child for medical decisions and another for financial management.

Durability: Both Are Automatically Durable in Maine

Under 18-C M.R.S. Section 5-904, a power of attorney in Maine is automatically durable — meaning it remains effective even after you become incapacitated — unless the document explicitly states otherwise.

This is the opposite of how it works in some other states, where you have to add "durable" language to make the document survive incapacity. In Maine, durability is the default. If you want a power of attorney to terminate upon your incapacity (a "springing" or non-durable POA), you must specifically say so in the document.

This automatic durability applies to both medical and financial powers of attorney.

Different Signing Requirements

This is where confusion causes real problems:

The critical distinction: your medical power of attorney does not need a notary to be legally valid (with one exception for burial authority). Your financial power of attorney must be notarized.

When Your Medical POA Takes Effect

By default, your healthcare agent's authority activates only when your primary physician determines that you lack the capacity to make your own medical decisions. Capacity means you can understand your condition, weigh treatment options, and communicate a decision.

You can override this default by including an "immediate effect" provision in your directive, giving your agent authority from the moment the document is signed. This is useful if you want your agent to communicate with your medical team on your behalf even while you are still competent — for example, during a hospitalization where you are conscious but too fatigued to manage conversations with multiple specialists.

What Your Medical Agent Can and Cannot Do

Can do:

• Consent to or refuse medical treatment, including surgery, medication, and life support
• Access your complete medical records under HIPAA
• Authorize transfer between hospitals, hospice, or care facilities
• Make decisions about pain management and comfort care
• Direct end-of-life treatment based on your documented wishes

Cannot do:

• Make financial decisions (that requires a separate financial POA)
• Override your explicit written instructions — if you wrote "no feeding tube under any circumstances," your agent must honor that
• Act while you still have capacity (unless you included an immediate-effect provision)
• Direct burial or cremation unless the document is notarized

Nominating a Guardian in Your Directive

Maine law allows you to nominate a guardian within your advance directive. If a court ever considers appointing a guardian for you — typically when there is a dispute about your care — the court must give priority to your nominated person.

This is a powerful safeguard. Without a nomination, a court-appointed guardian could be someone you would never have chosen. Including a guardian nomination in your medical POA adds one more layer of protection for a few minutes of additional paperwork.

Revoking or Changing Your Medical POA

You can revoke your medical power of attorney at any time by signing a written revocation, verbally notifying your healthcare provider, or executing a new advance directive (which supersedes the old one). After revocation, distribute updated copies to everyone who held the old version — your agent, alternate agent, physicians, hospitals, and any care facilities.

The Maine Advance Directive & Living Will Kit covers both the health care agent designation and how it coordinates with your financial power of attorney, including a side-by-side reference for signing requirements.
