What a Medical Power of Attorney Does

A medical power of attorney is a legal document that lets you name someone to make health decisions for you if you cannot make them yourself. That person — called your agent or attorney-in-fact — can consent to treatment, refuse treatment, access your medical records, and speak to doctors on your behalf. Unlike a general power of attorney, which covers financial and legal matters, a medical power of attorney covers only healthcare.

You stay in control as long as you are able to make decisions. Your agent steps in only if you become unconscious, mentally incapacitated, or otherwise unable to communicate your wishes. The document takes effect when ready in some states and only upon incapacity in others — you choose when you sign it.

A medical power of attorney is not the same as a living will, which states what medical treatment you do or do not want in specific end-of-life situations. Many people create both documents at the same time.

Key Takeaways

  • You can create a medical power of attorney yourself using your state's statutory form, which is free and legally valid without a lawyer.
  • Your agent must be at least 18 years old, mentally competent, and willing to act — usually a family member or close friend, not a healthcare provider treating you.
  • The document must be signed and dated in front of two witnesses or a notary public, depending on your state's rules.
  • You can revoke or change your medical power of attorney at any time while you are mentally capable, and you should tell your agent, doctor, and family what you have done.
  • Each state has its own form and rules, so you need the document for the state where you live, not where you work or own property.

Get Your State's Statutory Form

Every state has an official form for a medical power of attorney, often called a healthcare power of attorney or healthcare proxy form. Using your state's form is the simplest route because it is already written to meet state law and courts recognize it when ready.

Find your state's form through your state's bar association website, your state attorney general's office, or a free legal resource site like LawHelp.org or the National Hospice and Palliative Care Organization. Search "[your state] medical power of attorney form" or "[your state] healthcare proxy form." read the PDF, print it, and fill it out by hand or on your computer before you sign.

If you cannot find your state's official form, you can use a generic form from a legal document service, but verify that it complies with your state's laws. Some states have very specific requirements about what language must appear in the document.

Choose Your Agent and Alternates

Your agent should be someone you trust completely with your health information and someone willing to make decisions that match your values, even if those decisions are difficult. Most people choose a spouse, adult child, parent, or close friend. Your agent must be at least 18 years old and mentally competent to understand the responsibility.

Do not name your doctor, nurse, or other healthcare provider as your agent unless they are also a close family member. Many states prohibit healthcare workers from serving as agents because of conflicts of interest. If you live in a nursing home or long-term care facility, your agent cannot be an employee of that facility.

Name one or two alternate agents in case your first choice is unavailable, unwilling, or unable to serve when the time comes. Write their full legal names, addresses, and phone numbers on the form. Talk to each person before you sign — they need to know you have named them and understand what the role means.

Decide What Powers Your Agent Has

Most state forms let you check boxes to give your agent broad authority or to limit their power to specific decisions. A broad grant means your agent can consent to any medical treatment, refuse treatment, access your records, and make end-of-life decisions. A limited grant might restrict them to routine care only, or exclude certain decisions like organ donation or psychiatric treatment.

Think about what matters most to you. If you have strong feelings about life support, organ donation, or experimental treatment, you can exclude those decisions from your agent's power or add written instructions about them. Some people write a separate living will to spell out their wishes about end-of-life care and give that document to their agent along with the power of attorney.

If you do not check any boxes or add any limits, your agent will have broad power to make any healthcare decision. This is what most people choose because it gives the agent flexibility to respond to situations you cannot predict.

Sign and Witness the Document

Your state requires your signature to be witnessed or notarized. Most states require two adult witnesses who are not related to you and not named as your agent or alternate. Some states accept a notary public instead of witnesses. A few states accept both.

Read the witnessing requirements on your form — they vary by state. If your form says you need two witnesses, find two people who meet the rules, sit down with them and your agent, and sign the document in front of them. Each witness must also sign and print their name and address. If your form says you need a notary, make an appointment at a bank, law office, or notary service and bring the unsigned form and a photo ID.

Do not sign the document before you meet with your witnesses or notary. The signature must happen in front of them. If you sign it alone and then show it to witnesses, it is not valid.

Store and Share Your Document

Keep the original signed document in a safe place — a home safe, a safe deposit box, or with your agent. Make several photocopies. Give a copy to your agent, your primary care doctor, and any specialist you see regularly. Tell your family members where the original is kept and how to find it if you become incapacitated.

Some states have registries where you can file your medical power of attorney so that hospitals and doctors can find it if you arrive at an emergency room unconscious. Ask your state bar association or attorney general's office whether such a registry exists in your state and whether registration is worth doing.

If you move to a different state, check whether your document is still valid there. Some states recognize out-of-state powers of attorney; others do not. If you move permanently, you may need to create a new document using your new state's form.

Change or Revoke Your Medical Power of Attorney

You can revoke your medical power of attorney at any time while you are mentally capable of understanding what you are doing. You do not need a lawyer or a court order. You can revoke it by destroying the original document, signing a written revocation statement, or straightforward telling your agent and doctor that you are revoking it.

If you want to change your agent or modify the powers you have given, you can create a new document and revoke the old one. Sign the new document with the same witnessing or notarization requirements as the original. Give copies of the new document to your agent, doctor, and family, and tell them to disregard the old one.

Tell your agent, your doctor, and your family what you have done. If your agent does not know you have revoked the document, they may still try to act on it, and confusion could delay your care.

Frequently Asked Questions

Do I need a lawyer to create a medical power of attorney?

No. You can create a valid medical power of attorney yourself using your state's statutory form, two witnesses or a notary, and a pen. A lawyer can help if your situation is complicated — for example, if you have minor children, significant assets, or concerns about family conflict — but most people do not need one.

What happens if I do not have a medical power of attorney and I become unable to make decisions?

Your state has a law that names who can make decisions for you in order: usually your spouse, then adult children, then parents, then siblings. This is called the succession statute. Your family members can make decisions without a court order in most cases, but the process is slower and may cause conflict if family members disagree about what you would want.

Can my agent be paid for making decisions?

Your agent can be paid for reasonable expenses — travel, time off work, copying documents — but most states do not allow them to be paid a fee just for serving as agent. Check your state's law. If you want to compensate your agent, write that into the document or discuss it with them beforehand.

What if my agent and my doctor disagree about my treatment?

Your agent's decision is legally binding unless a court orders otherwise. If your doctor believes your agent is making a decision that is clearly harmful or against your known wishes, the doctor can ask a hospital ethics committee to review the situation or can seek a court order. This is rare and usually happens only in extreme cases.

Is a medical power of attorney the same as a do-not-resuscitate order?

No. A medical power of attorney names someone to make decisions. A do-not-resuscitate order (DNR) is a specific instruction telling paramedics and hospital staff not to perform CPR if your heart stops. You can have both documents, and your agent can help carry out the wishes in your DNR, but they are separate things.
