Notarization is required for some powers of attorney but not all — it depends on what the document will be used for

A power of attorney does not automatically need to be notarized. Many POAs are valid without notarization as long as they meet your state's basic requirements: a signature from you (the principal), a signature from the person you name (the agent), and sometimes a witness signature. However, banks, real estate companies, and government agencies often refuse to accept a POA unless it has been notarized, even if state law does not strictly require it.

The practical answer is that you should have your POA notarized unless you are certain it will only be used for informal family matters. A notarized POA costs between $10 and $50, takes 10 to 15 minutes, and removes the risk that an institution will reject your document later. If you are unsure whether the bank or agency that will use your POA requires notarization, call them first and ask — one phone call can save you from redoing the entire document.

Key Takeaways

  • State law does not require notarization for most POAs, but financial institutions and government agencies routinely demand it anyway.
  • A notarized POA costs between $10 and $50 depending on where you have it done, and takes 10 to 15 minutes.
  • You must appear in person before a notary public with a valid photo ID; the notary watches you sign and verifies your identity.
  • Real estate transactions, bank account access, and Medicaid planning almost always require notarization, even in states where it is technically optional.
  • Some states require notarization only for specific types of POAs, such as those used for real property or healthcare decisions.

Which states require notarization by law

Most states do not mandate notarization for a general financial power of attorney. However, some states do require it for certain types. For example, a few states require notarization for healthcare POAs or POAs that deal with real property. Your state's specific rules depend on the type of POA you are creating and what it will be used for.

The safest approach is to check your state's power of attorney statute or speak with a local attorney, because the rules vary. Even if your state does not legally require notarization, the institution that will use the POA — your bank, your county assessor, or a healthcare provider — may have its own rule that it will only accept a notarized version. That institutional requirement overrides what state law technically allows.

Why banks and government agencies demand notarization

Financial institutions and government offices require notarization not because state law forces them to, but because notarization reduces their risk. A notary public verifies your identity using a photo ID, watches you sign the document, and certifies that you appeared willing and not under pressure. This creates a paper trail that protects the bank or agency if someone later claims the POA was forged or signed under duress.

Real estate transactions are the clearest example. A county recorder will not file a deed signed under a POA unless the POA itself is notarized. Banks will not let an agent access accounts or move money without a notarized POA. Medicaid planning and nursing home admissions almost always require notarization. Even if your state's statute says notarization is optional, these institutions will turn away an unnotarized document.

How to get a power of attorney notarized

You must appear in person before a notary public with a valid photo ID — a driver's license, passport, or state ID card. Bring the unsigned POA document. The notary will ask you to confirm your identity, will watch you sign the document in front of them, and will then sign and stamp it with their official seal. The entire process takes 10 to 15 minutes.

You can find a notary at a bank (often free if you are a customer), a law office, a UPS Store, a FedEx Office, or through an online notary service that uses video conferencing. Costs range from $10 to $50 depending on where you go. Some notaries charge per signature, so if your POA requires both your signature and a witness signature, you may pay for two notarizations. Ask the notary about their fee before you sit down.

What happens if you use an unnotarized POA

An unnotarized POA may work fine for informal situations — for example, if you give it to a family member to handle a straightforward task and no third party ever sees it. But the moment you try to use it with a bank, a government agency, or a real estate transaction, you will likely hit a wall. The institution will ask for a notarized version, and you will have to start over.

In some cases, an institution may accept an unnotarized POA if you sign a separate acknowledgment form in front of a notary, but this is rare and varies by institution. The simpler path is to have the POA notarized from the start. The cost is small, and it saves you from having to redo the work later.

Notarization versus other POA requirements

Notarization is different from witnessing. Some states require one or two witnesses to sign the POA in addition to you and your agent. A witness is someone who sees you sign and confirms that you did so willingly — they do not verify your identity the way a notary does. A notary is a state-licensed official; a witness is just another person present. You can have both: witnesses sign, and then a notary notarizes the whole document.

Some states also require a POA to be recorded (filed with the county) if it involves real property. Recording is separate from notarization. You can record an unnotarized POA in some places, but most counties will not accept it. Again, notarization is the safest choice because it satisfies both the notarization requirement and makes recording possible.

When you might skip notarization

You can reasonably skip notarization only if the POA will be used solely within your family for informal purposes and no financial institution or government agency will ever see it. For example, if you give a POA to your adult child to sign documents at a doctor's office during a hospital stay, and the hospital does not require notarization, you may not need it. But even in this case, having it notarized costs so little that most people do it anyway to avoid surprises.

If you are unsure whether the institution that will use your POA requires notarization, call them and ask before you sign anything. They can tell you exactly what they need. This one phone call can save you the trouble of redoing the document later. Many banks and healthcare providers have this information readily available on their websites or can answer the question in under five minutes.

Frequently Asked Questions

Can I notarize my own power of attorney?

No. A notary cannot notarize a document they are a party to or have a financial interest in. If you are the principal signing the POA, you cannot be the notary. You must use a different notary public.

Does a notarized POA expire?

A notarized POA does not expire straightforward because it was notarized. Expiration depends on what the POA itself says and on your state's law. Some POAs last until you revoke them; others expire on a date you set. Notarization does not change the expiration date.

What if I sign the POA but do not get it notarized right away?

You can sign it first and have it notarized later, as long as you appear in person before the notary with your photo ID. The notary will notarize a document that was signed earlier. However, some institutions may question why there is a gap between the signature date and the notarization date, so it is cleaner to have both happen on the same day.

Do I need a notarized POA for online banking?

Most banks require a notarized POA before they will let an agent access online accounts or move money. Some banks have their own POA form that they require you to use instead of a state form. Call your bank and ask what they need before you create the document.

Can a notary refuse to notarize my POA?

Yes. A notary can refuse if you do not have a valid photo ID, if you appear confused or under pressure, if the document is illegible, or if they believe you are not the person you claim to be. A notary's job is to verify identity and may support the signer is willing, so they have the right to decline.
