A notary public verifies your identity and watches you sign documents to prevent fraud
A notary public is a person authorized by your state to witness signatures and confirm that the person signing a document is who they claim to be. They do not read the document, give legal information, or decide whether you should sign it. Their job is narrow: check your ID, watch you sign, and stamp the paper to prove they saw it happen. This creates an official record that the signature is genuine.
Notaries exist because some documents matter too much to leave unsigned. A bank needs proof you actually signed the mortgage. A court needs proof you signed the affidavit yourself, not someone else pretending to be you. A notary's stamp says "I checked the ID, I watched them sign, and I'm willing to swear to it in court if needed." That's why notaries carry liability insurance and why states regulate them.
Key Takeaways
- A notary checks your photo ID, watches you sign the document in front of them, and stamps it to create proof the signature is genuine.
- Notaries cannot give legal information, explain what a document means, or tell you whether you should sign it.
- You can find notaries at banks, UPS stores, law offices, and some government offices; many charge $5 to $15 per signature.
- Some documents require notarization by law (mortgages, powers of attorney, affidavits); others are notarized because one party wants proof the signature is real.
- A notary must be present in the same room as you and watch you sign; remote notarization is available in some states but follows stricter rules.
The three things a notary checks before stamping
When you sit down with a notary, they follow the same steps every time. First, they ask for a photo ID—a driver's license, passport, or state ID card. They check that the photo matches your face and that the ID has not expired. If your ID is expired, most notaries will refuse to notarize, even if you look exactly like the photo. The rule exists because an expired ID is not considered valid proof of identity in most states.
Second, they ask you to sign the document in front of them. You cannot hand them a document you signed last week. The notary must see your hand move across the paper. This is the core of their job—they are a witness to the act of signing, not just to the signature itself.
Third, they check that you understand what you are signing. They will ask, "Do you know what this document is?" or "Are you signing this of your own free will?" If you say no or seem confused, they can refuse to notarize. They are not checking whether the document is fair or legal—only whether you appear to be signing it knowingly and without pressure.
What documents usually need notarization
Some documents are notarized because the law requires it. A mortgage deed, a power of attorney, an affidavit sworn under penalty of perjury, and a will all typically need notarization in most states. Banks and courts will not accept them without the notary's stamp. If you are buying a house or creating a legal document that will go to court, you will almost certainly need a notary.
Other documents are notarized because one party wants proof. A landlord might ask a tenant to have a lease notarized. A business might ask you to notarize a signature on a contract. A school might ask you to notarize a permission slip if you are signing on behalf of someone else. In these cases, notarization is not legally required, but it shifts the risk: if the signature is later challenged, the notary's stamp proves you were there and you signed it yourself.
Some documents cannot be notarized. A notary will not notarize a blank document, a document you did not write, or a document you are signing on behalf of someone else without their knowledge. They also cannot notarize their own signature or a document in which they have a financial interest.
Where to find a notary and what it costs
Notaries work in many places. Banks often notarize for free if you have an account with them. UPS stores, FedEx offices, and some pharmacies have notaries on staff and charge $5 to $15 per signature. Law offices, title companies, and real estate offices notarize documents as part of their service. Some government offices, like county clerk's offices, have notaries available, sometimes for free or a small fee.
To find a notary near you, search online for "notary public near me" or call your bank and ask if they offer notarization. Many notaries work by appointment, so call ahead. Bring your photo ID and the document you need notarized. If the document is not yet signed, bring it unsigned—the notary will watch you sign it.
If you need notarization for a mortgage, title company, or legal document, the other party often arranges the notary and may cover the cost. Ask before you pay out of pocket.
Remote notarization: what it is and where it works
Some states allow remote notarization, in which you sign the document on a video call with a notary instead of in person. The notary watches you sign via webcam, checks your ID by looking at it on screen, and sends you a digitally stamped copy. This is faster and more convenient if you live far from a notary or cannot leave your home.
Remote notarization is not available in all states, and not all documents can be notarized remotely. Some states allow it only for certain types of documents or require additional steps, like recording the video call. If you need remote notarization, search for "remote notary" in your state or ask the organization requesting the notarization whether they accept remote notarized documents.
What a notary cannot do
A notary is not a lawyer and cannot give legal information. They cannot tell you whether a contract is fair, whether you should sign it, or what your rights are. They cannot explain what a document means or translate it into another language (unless they are a certified translator, which is a separate credential). If you have questions about the document itself, you need to ask a lawyer, not a notary.
A notary also cannot notarize a document they did not see you sign, cannot notarize a blank document, and cannot notarize a signature that is not in front of them. Some people ask a notary to notarize a document they signed weeks ago—notaries will refuse because they did not witness the signing.
How notary stamps and seals work
After you sign, the notary stamps the document with an official seal or embosser. The stamp includes the notary's name, their commission number, the state they are commissioned in, and the date. This stamp is proof that a notary was present and witnessed the signing. Courts and banks recognize it as official.
The stamp itself is not what makes the document legal—the notary's presence and their willingness to swear to what they saw is what matters. The stamp is just the record of it. If someone later claims you did not sign the document, the notary can be called to testify in court that they saw you sign it.
Notary seals vary by state. Some states require a raised embosser, others allow ink stamps, and some allow digital seals for remote notarization. The organization requesting the notarization will tell you what kind of seal they need.
Frequently Asked Questions
Can a notary refuse to notarize a document?
Yes. A notary can refuse if your ID is expired, if you do not appear to understand what you are signing, if you seem under pressure, or if the document is blank or unsigned. They can also refuse if they have a financial interest in the document or if they are related to you in some states. A notary's job is to protect against fraud, so they have the right to say no.
Do I need to bring anything besides my ID?
Bring your photo ID and the unsigned document. If the document is already signed, most notaries will refuse to notarize it because they did not witness the signing. Some notaries may ask for a second form of ID if your first one is close to expiring, but a valid photo ID is the main requirement.
What if I sign the document at home and then take it to a notary?
The notary will refuse. They must watch you sign the document in front of them. If you have already signed it, they cannot notarize it because they did not witness the signing. You will need to get a blank copy and sign it in front of the notary.
How long does notarization take?
Usually 5 to 10 minutes. The notary checks your ID, asks a few questions, watches you sign, and stamps the document. If you are notarizing multiple documents, it may take longer. Some notaries require an appointment; others take walk-ins.
Can a family member be a notary for me?
In most states, no. A notary cannot notarize a document for a spouse, parent, child, or sibling because they have a personal interest in the document. Some states have exceptions for certain types of documents. Check your state's notary rules or ask a notary whether they can help.
