How to Get a Medical Power of Attorney: Agent, Forms, and Signing

To get a medical power of attorney, choose someone you trust to make healthcare decisions for you, fill out your state’s statutory form naming that person as your agent, sign it with the witnesses or notary your state requires, and give copies to your agent and your doctors. In most states you can do this yourself, for free, without hiring a lawyer.

The document goes by different names depending on where you live — healthcare proxy, healthcare directive, medical power of attorney — but the function is the same: it names a specific person to speak for you when you cannot speak for yourself, and gives them authority to consent to or refuse treatments, choose providers, and make end-of-life decisions.

Step 1: Choose Your Agent and a Backup

Your agent must be a competent adult. Beyond that, most states bar your treating physician, employees of the facility where you receive care, and the owners of that facility from serving, unless they happen to be a close relative by blood, marriage, or adoption.

The harder question is practical. Your agent acts under what the law calls a “substituted judgment” standard, meaning they are supposed to make the decision you would make, not the one they would prefer. Someone who shares your values and can hold up under pressure in a hospital matters more than someone who simply agrees to the role. Have a direct conversation about life support, pain management, and organ donation before you finalize the paperwork. People who haven’t had that conversation tend to freeze when it counts.

Name a successor agent on the same form. If your first choice is unavailable, incapacitated, or unwilling when the moment arrives, a backup keeps the decision from defaulting to a court-appointed guardian.

Step 2: Get Your State’s Form

Every state publishes a statutory form for medical power of attorney, and using your state’s version is the simplest way to make sure the document will be accepted without argument. These forms are typically free on your state legislature’s website, your state attorney general’s health page, or your state department of health. Many hospitals and Area Agencies on Aging also stock printed copies.

You do not need a lawyer. The statutory forms are designed for people to complete on their own. If you have a complicated family situation, want to write in detailed conditions on your agent’s authority, or need to coordinate this with a broader estate plan, an attorney can help. Expect to pay roughly $150 to $400 for a lawyer-drafted medical power of attorney, though many estate planning attorneys bundle it with a financial power of attorney and a will for a flat package fee. Online legal services offer template-based versions for $35 to $150.

Use the form for your state of residence, not the state you happen to be in when you fill it out. If you split time between two states, complete forms for both.

Step 3: Fill Out the Form

The form asks for your full legal name, date of birth, and address, and the same information plus current phone numbers for your primary and successor agents. If a hospital cannot reach your agent during a crisis because the phone number on file is three years old, the document is effectively useless.

Next comes the scope of authority. Most forms let you either grant broad authority or set specific limits. You can restrict your agent’s power to certain types of decisions, exclude specific procedures, or set time limits. Common items to address include life-sustaining treatment, artificial nutrition and hydration, organ donation, and mental health treatment.

Some forms use checkboxes; others leave open space for narrative instructions. Either works legally, but be specific enough to give your agent real guidance. Writing “I don’t want extraordinary measures” leaves your agent guessing about what you consider extraordinary. Writing “If two physicians agree I have no reasonable chance of recovery, I do not want mechanical ventilation, CPR, or tube feeding” gives your agent something to work with.

If you already have a living will, check that the instructions in your medical power of attorney do not contradict it. When the two documents conflict, the result varies by state, and the ambiguity can paralyze everyone involved.

Include HIPAA language. Federal privacy law can block your agent from accessing your medical records unless the paperwork is in order. Several state statutory forms already contain HIPAA authorization; if yours does not, attach a separate HIPAA release naming your agent. Without it, providers may refuse to share information until their legal department reviews the document, which can cost critical time.

Step 4: Sign It the Way Your State Requires

Execution rules vary significantly. Roughly half of states require two witnesses and no notary. A smaller number require only a notary. Some require both, and several let you choose. Using both witnesses and a notary, even when your state only requires one, adds a layer of protection and makes the document more likely to be accepted if you need care in another state.

Witness restrictions exist to protect against coercion and self-dealing. Common disqualifications include your appointed healthcare agent, your treating physician, employees of your healthcare facility, and anyone who stands to inherit from your estate. In most states, at least one witness must have no financial connection to you at all. A neighbor or coworker with no stake in your medical decisions is the safest choice.

If your state requires or allows notarization, a licensed notary will verify your identity with a government-issued ID, watch you sign, and affix their seal. Notary fees typically run between $2 and $25 per signature, depending on the state. Many banks, UPS stores, and public libraries offer notary services, and some states now allow remote online notarization.

A document signed without the required witnesses or notary can be rejected by a hospital. Getting the execution right the first time is worth the small amount of extra effort.

Step 5: Distribute and Store the Signed Document

The original should go somewhere safe but accessible. A fireproof home safe works. A safe deposit box can be a problem if your agent cannot get into it on a weekend.

Give copies to:

  • Your primary agent
  • Your successor agent
  • Your primary care physician
  • Any hospital where you regularly receive treatment

Ask your doctor’s office to scan it into your electronic medical record. Some people also carry a wallet card noting that a medical power of attorney exists and listing the agent’s name and phone number, which is useful if you are hospitalized while traveling. The card itself has no legal force, but it tells emergency staff who to call.

When Your Agent’s Authority Actually Starts

In most states, your agent’s authority activates when a physician determines you lack the capacity to make your own decisions. This is a clinical judgment, not a court proceeding. Some states require a single attending physician to make the call; others require a confirming opinion from a second physician, particularly if the incapacity may relate to a mental health condition or developmental disability.

Until that determination is made, you keep full control. You can override your agent, change your instructions, or revoke the document entirely at any point while you have capacity. Signing the form does not hand your healthcare over to anyone.

A few states let you make the document effective immediately upon signing, so your agent can participate in decisions even while you still have capacity. If your state’s form offers this option, choose it deliberately rather than by accident.

Changing or Revoking It Later

You can revoke a medical power of attorney at any time, as long as you have the mental capacity to do so. Most states allow both oral and written revocation, but the safer approach is to put it in writing, have it notarized, and send it by certified mail to your former agent. Then notify every person and provider who received a copy of the original.

If you create a new medical power of attorney, include a clear statement that all prior versions are revoked. Without that language, some states treat both documents as valid, which creates confusion about who has authority. Destroy all copies of the old document you can locate.

Revocation is not effective against anyone who acts in good faith without knowing about it. If a former agent shows up at a hospital with a copy of the old document and the hospital has no reason to think it was revoked, the hospital may follow their instructions. Notifying providers promptly matters as much as the revocation itself.

Plan to review the document every few years, after any major health change, and especially after a divorce or falling-out with your named agent. An outdated form naming an ex-spouse can create exactly the kind of conflict the document was meant to prevent.

If You Live In or Travel Between Two States

Most states have provisions recognizing medical powers of attorney executed elsewhere. The typical standard is that an out-of-state document will be honored if it was valid where signed or if it meets the requirements of the state where treatment is being provided.

Not every state has an explicit reciprocity provision, though, and even in states that do, individual hospitals may hesitate over an unfamiliar form while a legal department reviews it. If you spend significant time in a state other than your home state, execute a version that complies with that state’s specific form and witness rules. Maintaining two forms costs very little compared to having your agent turned away during an emergency.
