Most powers of attorney require a notary, but the rule depends on your state and how you plan to use the document

Whether you need a notary for a power of attorney comes down to where you live and what the document will do. Some states require notarization by law; others make it optional but strongly recommend it; a few states allow certain powers of attorney without one. The safest approach is to assume you need a notary unless you have checked your state's specific rules or spoken with the person or institution that will accept the document.

A notary does not decide whether your power of attorney is valid or legal—that is your state's job. What a notary does is witness your signature, confirm your identity, and certify that you signed the document willingly and without pressure. Banks, healthcare providers, and government agencies often refuse to honor a power of attorney unless a notary has done this, even if your state does not legally require it. That is why notarization is the practical standard almost everywhere.

Key Takeaways

  • Most states require a notary to witness and certify your signature on a power of attorney, though a few allow certain types without one.
  • Even if your state does not legally require notarization, banks and healthcare providers often will not accept the document without it.
  • You must sign the document in front of the notary in person; they cannot notarize a document you signed earlier or remotely.
  • A notary charges a small fee (usually $5 to $15 per signature) and takes only a few minutes to complete the work.
  • Some states now allow remote notarization through video, which can be faster than visiting a notary in person.

Which states require notarization and which do not

About 40 states require a notary's signature and seal on a power of attorney as a matter of law. These include California, New York, Texas, Florida, and most others. In these states, a power of attorney without notarization is not legally valid, period.

A smaller group of states—including some in the Midwest and South—do not legally require notarization but strongly encourage it. In these places, a power of attorney can be valid without a notary, but you will have a much harder time getting a bank or hospital to accept it. The document will look incomplete to them, and they may refuse to act on it or demand additional proof.

A handful of states allow certain types of power of attorney to skip notarization entirely. For example, some states permit a durable power of attorney for healthcare to be valid with only your signature and a witness (not a notary). However, even in these states, adding a notary makes the document stronger and more likely to be accepted without question.

The only way to know your state's exact rule is to check your state's laws directly or ask an attorney. Your state bar association website usually has this information, or you can call your county clerk's office.

Why banks and healthcare providers demand notarization anyway

Even in states where notarization is optional, most financial institutions and healthcare systems have their own internal rules requiring it. A bank's legal department does not want to risk honoring a power of attorney that might be forged, coerced, or signed by someone who lacked the mental capacity to do so. A notary's certification—their signature, seal, and record of the transaction—protects the bank from liability.

Healthcare providers follow the same logic. A hospital will not let someone make medical decisions on your behalf based on a document they cannot verify. They want to see that a neutral third party watched you sign it and confirmed you were who you said you were.

This means that even if your state does not require notarization, you should treat it as mandatory if you plan to use the power of attorney with a bank, brokerage, insurance company, or hospital. The cost is small, and it saves you from a frustrating conversation later when the institution refuses to accept your document.

How the notarization process works

Notarization is straightforward and takes about five minutes. You bring the unsigned power of attorney document and a photo ID to a notary. The notary will ask you to sign the document in front of them while they watch. They will then sign and stamp the document with their official seal, and sometimes record the transaction in a notary journal.

The notary is not reading your document or checking whether it is legally correct. They are only confirming three things: that you are the person whose name is on the document, that you signed it willingly, and that you appear to understand what you are doing. If you seem confused, coerced, or unable to communicate, a notary can refuse to notarize the document.

You must sign the document in the notary's presence. A notary cannot notarize a document you signed days ago or a copy you made yourself. The signature has to happen in front of them, and they have to watch it happen.

Where to find a notary and what it costs

Notaries are widely available and inexpensive. You can find one through several routes:

  • Your bank or credit union: Most offer notary services free or for a small fee, even if you are not a customer. Call ahead to confirm they are available and ask whether they charge.
  • Your employer: Many large companies have a notary on staff or contract with one. Check with your HR or administrative office.
  • UPS Store or FedEx Office: Both chains employ notaries at most locations. Fees are usually $5 to $15 per signature.
  • Local law offices: Attorneys often notarize documents for a small fee, even if they did not draft the document.
  • County clerk's office: Many counties employ notaries who are open to the public, usually for $5 or less per signature.
  • Online notary services: Some states now allow remote notarization through video. Services like Notarize, LegitScan, and others let you complete the process from home, though fees are typically higher ($50 to $100).

Bring your unsigned power of attorney document and a valid photo ID (driver's license, passport, or state ID). The notary will not need anything else from you.

Remote notarization: what you need to know

A growing number of states now permit remote notarization, meaning you can have a notary watch you sign the document over a video call instead of in person. This is faster if you live far from a notary or have mobility issues, but it comes with caveats.

Not all states allow remote notarization for powers of attorney. Some states permit it only for certain types of documents or only if you have an existing relationship with the notary. Before you pay for a remote notarization service, confirm that your state recognizes it for your specific type of power of attorney.

Remote notarization also costs more—typically $50 to $100 per signature—because the service provider has to verify your identity through additional steps, like checking your ID against a database or asking security questions. In-person notarization at a bank or UPS Store is almost always cheaper and faster if it is available to you.

What happens if you skip the notary

If your state requires notarization and you do not get it, your power of attorney is not legally valid. A court will not enforce it, and no institution will accept it. You will have wasted the time it took to draft the document.

If your state does not require notarization but you skip it anyway, the document may still be valid in theory, but in practice it will be nearly useless. Banks will refuse it. Healthcare providers will refuse it. The person you named as your agent will not be able to act on your behalf. You will have to go back and get it notarized, or draft a new one and have that notarized.

The only scenario where you can safely skip notarization is if you have confirmed in writing with the specific institution that will use the document (your bank, your healthcare provider, your brokerage) that they will accept it without a notary. Even then, get it notarized anyway. The cost is negligible, and it protects you against future problems.

Frequently Asked Questions

Can I notarize a power of attorney that someone else drafted for me?

Yes. The notary does not care who wrote the document or whether it is legally correct. They only care that you are signing it willingly and in their presence. If you are unsure whether the document is legally sound, have an attorney review it before you sign, but the notary will not do that for you.

What if I cannot get to a notary in person?

Check whether your state allows remote notarization. If it does, you can use an online service to have a notary watch you sign over video. If your state does not allow remote notarization, you will need to visit a notary in person—there is no legal workaround.

Do I need the notary to be a lawyer?

No. A notary is a separate credential from being a lawyer. Any notary can notarize your power of attorney. You do not need to pay for an attorney to do it unless you also want legal information about whether the document is correct.

Can a family member notarize my power of attorney?

No. Most states prohibit a notary from notarizing a document for a close relative (spouse, parent, child, sibling). The notary has to be an independent third party with no financial interest in the document. Check your state's rules, but assume a family member cannot do it.

How long does a notarized power of attorney last?

That depends on the type of power of attorney and your state's law. A durable power of attorney lasts until you revoke it or die, even if you become incapacitated. A non-durable power of attorney ends if you become incapacitated. The notary's job is only to witness your signature; they have nothing to do with how long the document remains valid.
