Notarization requirements vary by state, and most states do not require it

A medical power of attorney does not need to be notarized in most states. However, some states require notarization, and even in states where it is optional, having it notarized makes the document stronger and harder to challenge later. The safest approach is to check your state's specific rules before you sign, because the requirement depends entirely on where you live and sometimes on which hospital or healthcare facility will be using the document.

If your state does not require notarization but your doctor's office or hospital asks for it anyway, you should have it done. Healthcare providers sometimes request notarization as their own internal policy, even when state law does not mandate it. A notarized document carries more weight and reduces the chance that a provider will question whether you actually signed it or whether you had the mental capacity to do so at the time.

Key Takeaways

  • Most states do not legally require notarization for a medical power of attorney, but some do, so you must check your state's laws before signing.
  • Even when notarization is not required by law, hospitals and doctors may request it as part of their own procedures.
  • A notarized document is harder to challenge and gives healthcare providers more confidence that the document is valid.
  • Notarization typically costs between $5 and $15 per signature and takes less than ten minutes at a bank, courthouse, or notary service.
  • Some states require witnesses instead of or in addition to notarization, so read your state's rules carefully.

Which states require notarization

States that require notarization for a medical power of attorney include Alabama, Alaska, Arizona, Arkansas, Delaware, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.

If you live in a state not listed above, notarization is typically optional but still recommended. California, Colorado, Connecticut, Massachusetts, and a few others do not require it by law. Even in these states, having the document notarized removes doubt and makes it easier for hospitals and doctors to accept it without question.

How to get your medical power of attorney notarized

To have your document notarized, you need to find a notary public and bring the unsigned medical power of attorney with you. Notaries are available at most banks during business hours, at UPS stores, at county courthouses, and through online notary services. Call ahead to confirm the notary is available and ask whether they charge a fee — most charge between $5 and $15 per signature, though some banks offer notarization free to customers.

When you arrive, bring a government-issued photo ID such as a driver's license or passport. The notary will watch you sign the document in front of them and will then sign and stamp it themselves. This process usually takes fewer than ten minutes. Do not sign the document before you meet the notary — the notary must see you sign it. If your state requires witnesses as well as notarization, bring those witnesses with you to the notary's office so everyone can sign at the same time.

States that require witnesses instead of notarization

A few states allow you to use witnesses instead of notarization. These states typically require two witnesses who are not related to you and not your healthcare provider. The witnesses must watch you sign the document and then sign it themselves as proof that you appeared to understand what you were signing and that you signed it willingly.

Even if your state allows witnesses instead of notarization, notarization is still a stronger option because a notary is a neutral third party trained to verify identity, whereas witnesses can be questioned about their relationship to you or their bias. If your state gives you a choice, notarization is the safer route.

What happens if you do not notarize when you should

If your state requires notarization and you sign a medical power of attorney without having it notarized, the document may not be accepted by hospitals or doctors. A healthcare provider might refuse to honor your wishes because they cannot verify that the document is valid. This can create serious problems if you become unable to make your own medical decisions and your agent needs to step in when ready.

If you have already signed a medical power of attorney without notarization and your state requires it, you can sign a new one with notarization. You do not need to destroy the old one, but the new notarized version will be the one that hospitals and doctors will trust. Keep both copies in a safe place and give a copy to your agent and your primary care doctor.

Online notarization and remote options

Many states now allow remote notarization, which means a notary can verify your identity and watch you sign through a video call. This is useful if you cannot travel to a bank or courthouse. Services like Notarize, LegitScript, and some state bar associations offer remote notarization for a fee, usually between $25 and $50. The process takes about fifteen minutes, and you receive a digitally notarized copy by email.

Before using an online notary service, confirm that your state accepts remote notarization for medical powers of attorney. Not all states do, and some have restrictions on which documents can be notarized remotely. Your state's secretary of state office can tell you whether remote notarization is allowed in your state.

Keeping your notarized document safe

Once your medical power of attorney is notarized, store the original in a safe place such as a fireproof safe, a safe deposit box at a bank, or with your attorney. Give a copy to your healthcare agent, your primary care doctor, and any hospital where you receive regular care. Do not keep the original in a safe deposit box that only you can access, because your agent may not be able to retrieve it if you become incapacitated.

Some people store a copy with their will or other important documents. Others keep it with their healthcare provider. The key is making sure your agent knows where the original is and can access it quickly if needed. You should also tell your agent that the document has been notarized, so they know it carries the full legal weight of a notarized document.

Frequently Asked Questions

Can I notarize a medical power of attorney myself?

No. A notary public must be someone other than you, the person signing the document. If you are a notary, you cannot notarize your own medical power of attorney. You must find a different notary to do it.

Do I need both a witness and a notary?

It depends on your state. Some states require only notarization, some require only witnesses, and some require both. Check your state's laws or contact your state bar association to find out what your state requires.

What if my state does not require notarization but my hospital asks for it?

You should have it notarized anyway. Hospitals and doctors set their own internal policies, and notarization makes the document stronger and easier for them to accept. The cost is small, and it removes any doubt about the document's validity.

How long does a notarized medical power of attorney last?

A notarized medical power of attorney remains valid until you revoke it or until you die, unless your state has a specific expiration date written into law. Some states require you to renew it every five or seven years. Check your state's rules to see whether renewal is necessary.

Can I update a notarized medical power of attorney?

Yes. If you want to change your agent, your healthcare wishes, or any other part of the document, you can sign a new one and have it notarized. Keep the old one in case questions arise about what you intended at different times, but make clear to your agent and your doctors which version is current.
