Notarization requirements vary by state, but most states require a medical power of attorney to be notarized before it becomes valid
Whether your medical power of attorney needs notarization depends on your state's laws. Most states require it—some make it mandatory, others make it optional but strongly recommended. A few states do not require notarization at all. The document is typically signed in front of a notary public, who verifies your identity and confirms you are signing of your own free will, then stamps and signs the document themselves.
If you do not notarize when your state requires it, the document may be rejected by hospitals, doctors, or other healthcare providers. Even if notarization is optional in your state, having it done protects you because it creates an official record that you were competent and acting voluntarily when you signed. This matters most if someone later challenges the document or questions whether you understood what you were doing.
Key Takeaways
- Most states require notarization of a medical power of attorney, though a few allow it without a notary if witnesses sign instead.
- Your state's specific rules determine what is required—check your state's health department website or ask an attorney before signing.
- A notary public verifies your identity and watches you sign, then adds their official seal and signature to the document.
- Even when notarization is optional, having it done makes the document stronger and less likely to be challenged later.
- You can find notaries at banks, UPS stores, libraries, and online notary services, though online notaries may not be accepted in all states yet.
Which states require notarization and which do not
About 30 states require notarization of a medical power of attorney as a legal requirement. These include California, Florida, New York, Texas, and Pennsylvania. In these states, a healthcare provider can refuse to honor an unnotarized document.
Some states allow notarization to be skipped if you have two adult witnesses sign the document instead. These states include Georgia, Illinois, and Ohio. The witnesses must usually be unrelated to you and not be the person you named as your agent. A few states—including Alaska and Wyoming—do not require either notarization or witnesses, though having one or both is still a good idea.
The safest approach is to check your specific state's requirements before you sign. Your state's health department, secretary of state office, or a local attorney can tell you what your state requires. Many states post their medical power of attorney forms online with instructions that spell out the notarization rule.
What happens during the notarization process
When you meet with a notary public, bring a photo ID. The notary will ask you to confirm your identity, verify that you are signing the document willingly (not under pressure), and watch you sign in front of them. They will then add their official seal, signature, and the date to the document. The whole process usually takes 5 to 10 minutes.
You do not need to bring a witness if notarization is required in your state—the notary's seal replaces the witness signature. However, if your state allows witnesses instead of notarization, you will need two unrelated adults present when you sign, and they will sign as witnesses rather than having a notary involved.
Some notaries will come to your home or hospital if you cannot travel, though this usually costs more. Online notary services have grown in recent years, but not all states accept them yet for medical powers of attorney. Check whether your state recognizes remote notarization before using an online service.
Where to find a notary public
Banks often notarize documents for customers at no charge. Call ahead to confirm they offer this service and ask whether you need an appointment. UPS stores, FedEx Office locations, and some CVS pharmacies also provide notary services for a small fee, usually $5 to $15 per signature.
Public libraries in many areas offer free or low-cost notary services. Your county clerk's office or courthouse may also have a notary available. Search online for "notary public near me" to find local options, or ask your doctor's office—many healthcare facilities have notaries on staff or can refer you to one.
Online notary services like Notarize, NotaryCam, and LegitScan allow you to upload your document and meet with a notary via video call. They verify your identity using your driver's license and watch you sign electronically. However, some states and healthcare providers do not yet accept electronically notarized medical powers of attorney, so confirm this is acceptable in your state before using an online service.
Common mistakes to avoid when getting notarized
Do not sign the document before you meet the notary. The notary must watch you sign—if you sign it ahead of time, the notarization is invalid. Bring the unsigned document with you to the notary's office.
Make sure the notary fills in all required information on the notarization section, including the date, your name, the notary's name, and their commission number. An incomplete notarization can cause healthcare providers to reject the document. Ask the notary to make a copy for your records before you leave.
If your state allows witnesses instead of notarization, do not use both—pick one method and follow it completely. Mixing the two can create confusion about whether the document is valid. Check your state's rules to see which method is required or preferred.
What to do if your state does not require notarization
If your state does not require notarization, you still have the option to get it done. Many people choose to notarize anyway because it strengthens the document and makes it less likely that a healthcare provider or family member will question it later. The small cost and time investment can prevent problems down the road.
If you decide not to notarize, make sure you follow your state's witness requirements exactly. Have the required number of witnesses present, make sure they are unrelated to you and not your agent, and have them sign in front of you. Keep the original signed document in a safe place and give copies to your agent, your doctor, and any hospitals where you receive care.
Frequently Asked Questions
Can I notarize a medical power of attorney online?
Some states now accept online notarization for medical powers of attorney, but not all do yet. Check your state's health department website or ask your doctor's office whether they will accept a remotely notarized document. If you use an online notary service, keep a copy of the video recording and the notary's credentials in case you need to prove the document is valid.
What if I cannot leave my home to get notarized?
Many notaries will travel to your home, hospital, or nursing facility for an additional fee. Call local notary services or your county clerk's office to ask about mobile notary options. Some online notary services also allow you to sign from home using a video call, though you will need to confirm your state accepts this method.
Do I need to notarize a medical power of attorney if I already have a living will?
A living will and a medical power of attorney are different documents with different purposes. Your state's notarization rules explore to each one separately. Check what your state requires for both documents and follow those rules for each one you create.
What happens if I sign the document but forget to get it notarized?
If notarization is required in your state and you did not get it done, the document may be rejected by healthcare providers. You can have it notarized later—bring the signed document to a notary and they can notarize your existing signature. However, it is better to have it notarized at the time you sign to avoid any questions about when you signed or whether you were competent.
Can a family member be a notary for my medical power of attorney?
Most states do not allow a notary to notarize a document for a close family member, and some states prohibit it entirely. Even if it is technically allowed, it weakens the document because it raises questions about whether the notary was truly impartial. Use a notary who is not related to you or your agent.
