What a notary does and why it matters
A notary public is a person authorized by your state to witness you sign a document and verify that you are who you say you are. They do not read the document, give legal information, or decide whether it is a good idea for you to sign it. Their job is narrower: they confirm your identity, watch you sign, and stamp the document with an official seal that says "I saw this happen on this date."
The notary's stamp carries legal weight because the notary is bonded and registered with the state. If someone later claims you did not actually sign the document, or that you were forced to sign it, the notary's seal is evidence that you were present and willing. Banks, courts, and government agencies accept notarized documents because they trust that a notary followed the rules.
You need notarization for documents that involve money, property, or legal rights—things where fraud or coercion would cause real harm. A mortgage, a power of attorney, an affidavit, or a deed usually requires notarization. A grocery list does not.
Key Takeaways
- A notary verifies your identity by checking a government-issued ID, watches you sign the document in person, and stamps it with an official seal.
- You must be physically present in front of the notary; they cannot notarize a document you sign elsewhere or mail to them.
- The notary does not read or understand the document—they only confirm that you signed it willingly and that you are the person named in it.
- Notaries are available at banks, UPS stores, law offices, and independent notary services; fees range from a few dollars to $15 per signature depending on location and the notary.
- The notary keeps a record of every document they notarize in a journal, which the state can inspect to prevent fraud.
How the notary verifies your identity
Before the notary will stamp anything, they must see a government-issued photo ID. This is almost always a driver's license, passport, or state ID card. The notary checks that the photo matches your face, that the ID has not expired, and that the name on the ID matches the name on the document you are signing.
If you do not have a photo ID, some notaries will accept a combination of other documents—a utility bill plus a credit card, for example—but this is less common and depends on state law and the notary's comfort. The safest approach is to bring your driver's license or passport.
The notary writes down your ID number, the type of ID, and the expiration date in their journal. This record is part of what makes notarization trustworthy: if someone later forges a notary seal, the state can check the journal and see whether the notary actually performed the work.
What happens when you sign in front of the notary
You sit across from the notary with the unsigned document in front of you. The notary may ask you to read it aloud or may straightforward ask, "Do you understand what this document says?" Your answer does not matter to them—they are not checking whether you understand it, only that you are signing it of your own will and not under duress.
You then sign the document in the notary's presence. The notary watches you sign. They do not sign for you, and they do not let you sign it beforehand and then bring it to them—the signature must happen in front of them. If the document has multiple signature lines, you sign all of them while the notary watches.
After you sign, the notary signs and stamps the document. The stamp includes the notary's name, their commission number, the state, and the date. Some notaries also add a thumbprint or other details depending on state rules. The document is now notarized.
Where to find a notary and what it costs
Notaries work in many places. Banks often have a notary on staff, sometimes for free if you are a customer. UPS stores, FedEx Office, and similar shipping centers employ notaries and charge a fee per signature—usually $5 to $15. Law offices have notaries. Some counties run notary services. Independent notaries advertise online and work from home offices or small storefronts.
Fees vary widely by location and by the notary. A small town may have one notary who charges $10 per signature. A city may have dozens competing on price. Some notaries charge extra if you need multiple documents notarized or if you ask them to travel to you. Always call ahead to ask the fee and whether they are available at the time you need them.
If you need a notary urgently, call your bank first—many offer it free or cheap to customers. If that does not work, search "notary near me" online or call your county clerk's office, which can usually refer you to a local notary.
What notaries cannot do
A notary cannot tell you whether the document is legal, fair, or a good idea. They cannot explain what it means or advise you on whether to sign it. If you have questions about the document itself, you need a lawyer, not a notary. The notary's only job is to verify identity and witness the signature.
A notary cannot notarize a document they did not watch you sign. If you sign something at home and mail it to a notary, they will refuse. If you sign it in front of a notary but the notary did not watch you sign it—for example, you signed it before walking in—they cannot notarize it. The signature must happen in their presence.
A notary cannot notarize a document for themselves or for a close family member in most states. This rule exists to prevent fraud. If you need a document notarized and the only notary you know is your spouse, you will need to find a different notary.
What the notary's seal means to banks and courts
When a bank or court sees a notary seal on a document, they know that someone officially confirmed your identity and watched you sign. This does not mean the document is true or that you understood it. It means the notary performed their job correctly on that date.
If a document is notarized and you later claim you did not sign it, the notary's journal is evidence against you. The notary can testify that you were present and signed willingly. This is why notarization matters for mortgages, wills, powers of attorney, and other high-stakes documents—it creates a record that is hard to dispute.
Some documents require notarization by law. A deed transferring property almost always does. A power of attorney usually does. A mortgage always does. Other documents do not require it but may be stronger if they are notarized. Always check the specific requirement for the document you are signing.
How to prepare for your notary appointment
Bring your government-issued photo ID—a driver's license or passport. Bring the unsigned document. If the document has blank lines for the notary's information, leave them blank; the notary will fill them in. Do not sign the document before you arrive.
If you are unsure whether the document needs notarization, check the document itself or ask whoever gave it to you. Some documents have a section that says "Notary Public" at the bottom; others do not. If you are still unsure, call the notary and describe the document—they can tell you whether they can notarize it.
Arrive a few minutes early. Bring cash or a card if you expect to pay a fee. If the document is long or complex, you do not need to read it beforehand, but it helps to know roughly what it is about so you are not surprised when you sign.
Frequently Asked Questions
Can a notary notarize a document I sign electronically or by email?
Not in the traditional sense. You must sign in front of the notary in person. However, some states now allow remote online notarization, where you sign on a video call while the notary watches. This is newer and not available everywhere, so ask your notary whether they offer it.
What if I lose the notarized document after the notary stamps it?
The notary keeps a copy or a record in their journal, but you cannot get a certified copy from them unless your state law allows it. You will need to contact whoever issued the original document—the bank, the court, or the agency—and ask for a replacement. The notary's seal is on the original, not on copies.
Do I need a notary if the document says "notarization optional"?
No. If notarization is optional, you can sign without it. However, a notarized version is stronger evidence if someone later disputes whether you signed it. If the document involves money or property, notarization is usually worth the small fee.
Can a notary refuse to notarize a document?
Yes. A notary can refuse if they believe the document is fraudulent, if you appear to be under duress, if your ID does not match your appearance, or if state law prohibits them from notarizing that type of document. They can also refuse if you are not physically present or if you refuse to sign in front of them.
How long does a notary seal last?
The seal itself does not expire. Once a document is notarized, it remains notarized forever. However, the notary's commission expires—usually every four to ten years depending on the state. If a notary's commission has expired, their old seals are still valid, but they cannot notarize new documents.
