The Basic Signing Process

To sign a power of attorney, you must sign the document in front of a notary public, and in most states that is the only requirement. You do not need a lawyer present, though you can hire one if you want to. The notary watches you sign, verifies your identity with a government-issued ID, and then signs and stamps the document themselves. This notarization proves you signed it willingly and knew what you were doing.

Some states require witnesses in addition to a notary — typically one or two people who watch you sign and then sign the document themselves. A few states require both a notary and witnesses. Check your state's rules before you sign, because signing without the right witnesses or notary means the document will not be valid.

Key Takeaways

  • You must sign in front of a notary public in all states, and some states also require one or two witnesses to watch you sign.
  • The notary checks your government-issued ID, watches you sign, and then notarizes the document with their stamp and signature.
  • Witnesses (if required) must be present when you sign, cannot be the person you are giving power to, and must sign the document themselves.
  • You can find a notary at a bank, UPS Store, or online search for "notary public near me" — most charge $5 to $15 per signature.
  • Sign the exact same way every time — use the same name spelling and signature style you use on other legal documents.

Finding a Notary Public

A notary public is someone licensed by your state to witness signatures and verify identity. You can find one at a bank (often free if you have an account), a UPS Store, a FedEx Office, a local law office, or an online notary service. Search "notary public near me" to see what is available in your area. Most charge between $5 and $15 per signature, though some banks do it free for customers.

If you use an online notary, you will sign electronically on a video call while the notary watches. This works for most power of attorney documents, though a few states still require in-person notarization. Call ahead to confirm the notary can handle a power of attorney — some only do straightforward documents like affidavits.

What to Bring to the Notary

Bring your signed power of attorney document and a government-issued photo ID. The notary will check your ID to make sure you are who you say you are. Bring the original document, not a photocopy — the notary must see your actual signature on the paper.

If your state requires witnesses, bring them with you. They must be present when you sign and when the notary notarizes the document. Witnesses cannot be the person you are giving power to (called the agent or attorney-in-fact), and they cannot be your spouse or close relative in most states — check your state's rules to be sure.

Signing the Document Correctly

Sign your name exactly as it appears on your government-issued ID. If your ID says "Robert James Smith," sign it that way every time, not as "Bob Smith" or "R.J. Smith." Use the same signature style you use on other legal documents like bank forms or contracts. The notary will compare your signature to your ID, so they must match.

Sign in black or blue ink — do not use pencil or erasable pen. Sign on the line marked for your signature, and do not cross out or white-out any part of the document. If you make a mistake, ask the notary whether you should sign a new copy or whether they can correct it. Some notaries will let you initial a small correction; others will require a fresh document.

After the Notary Stamps the Document

Once the notary stamps and signs the document, it is valid. The notary will give you the original notarized copy. Keep this original in a safe place — a safe deposit box, a fireproof safe at home, or with your attorney. Make photocopies for your records and for the person you are giving power to (your agent).

Some institutions, like banks or healthcare providers, may ask to see the notarized original before they will honor the power of attorney. Do not send the original through the mail unless necessary. Instead, offer to bring it in person or send a certified copy. If you need certified copies, ask the notary whether they can provide them — some can, and some cannot.

State-Specific Signing Rules

A few states have special requirements. For example, Florida requires two witnesses and a notary. California allows a notary alone but has specific language the document must include. New York requires either a notary or two witnesses, but not both. Texas allows notarization or two witnesses.

Before you sign, look up your state's power of attorney rules online or ask a notary what your state requires. Many notaries know the rules for your state and will tell you what you need. If you are unsure, a brief conversation with a lawyer in your state costs far less than signing a document that turns out to be invalid.

Common Mistakes to Avoid

Do not sign the document before you meet the notary. The notary must watch you sign — if you sign it at home and then bring it to the notary, it is not valid. Do not use a different name or signature style than what is on your ID. Do not skip witnesses if your state requires them, and do not use someone who is not allowed to be a witness (like your agent or spouse, depending on your state).

Do not assume an online notary will work in your state — call ahead and confirm. Do not use a photocopy of a notarized document if the institution asks for the original; some will not accept copies. Do not store the original in a place where no one can find it if you become unable to communicate — tell your agent and a trusted family member where it is kept.

Frequently Asked Questions

Can I sign a power of attorney without a notary?

No. Every state requires a notary public to witness and notarize your signature. Some states also require witnesses in addition to the notary, but no state allows you to skip the notary. A power of attorney signed without notarization is not valid.

What if I cannot leave my home to see a notary?

Many notaries will come to your home for an additional fee, usually $25 to $50. You can also use an online notary service, where you sign electronically on a video call. Confirm that online notarization is legal in your state before you use this method.

Do I need a lawyer to sign a power of attorney?

No. A lawyer is not required to sign the document. However, a lawyer can review the document before you sign to make sure it says what you want it to say. This is especially useful if you have complex finances or health wishes.

What happens if I sign the document wrong?

If you sign it incorrectly — for example, with the wrong name or without a notary present — the document is not valid. Your agent cannot use it, and institutions will refuse to honor it. You will need to sign a new copy correctly. This is why it is important to get the signing right the first time.

Can I change my mind after I sign?

Yes. You can revoke a power of attorney at any time by signing a written revocation document and notarizing it. Give copies to your agent and to any institutions that have a copy of the original power of attorney. The revocation takes effect when they receive it.
