Getting something notarized means a notary public has witnessed you sign a document and verified your identity

When you get a document notarized, a notary public watches you sign it in person, checks your government-issued ID to confirm who you are, and then adds their official stamp and signature to the paper. That stamp and signature are a record that says: "I saw this person sign this document on this date, and I checked their ID." The notary does not read the document, does not judge whether it is a good idea, and does not verify that what is written in it is true. They are only confirming that you are who you say you are and that you signed it yourself.

Notarization is not the same as having a lawyer review a document or having it filed with a government office. It is straightforward a witness stamp. But that stamp matters because it makes it much harder for someone to claim later that your signature was forged or that you never signed the paper at all.

Key Takeaways

  • A notary watches you sign a document, checks your ID, and stamps the paper to prove they witnessed your signature.
  • Notarization does not mean a document is legal or that its contents are true—it only proves you signed it yourself.
  • Many financial, legal, and real estate documents require notarization because it makes it harder for someone to forge your signature later.
  • You must sign the document in front of the notary; they cannot notarize a signature you made before you arrived.
  • Notaries charge a fee, usually between $5 and $25 per signature, though some banks and employers offer it free to customers or employees.

Why documents need to be notarized

Notarization exists to prevent fraud. If you sign a power of attorney, a deed, or a loan document, the other party wants proof that you actually signed it and that you were not forced or tricked into signing. A notary's stamp creates a record: if someone later claims you never signed the paper, or that your signature was forged, the notary can testify that they watched you do it.

Banks, courts, and government agencies often require notarization for documents that transfer money, property, or legal authority. A mortgage lender will not fund a home purchase without notarized signatures on the deed. A court will not accept a power of attorney unless a notary has witnessed the signature. Some states require notarization for wills, though not all do. If you are unsure whether a document needs notarization, the person or organization asking you to sign it will tell you.

What the notary actually checks

The notary's job is narrow. They check that you have a valid government-issued ID—usually a driver's license, passport, or state ID card—and that the name on the ID matches the name on the document you are signing. They watch you sign the document yourself; they do not accept a signature you made earlier. They record the date and the type of ID you showed them. Then they stamp the document and sign it.

The notary does not verify that the document is legal, that you understand what you are signing, or that the facts in the document are correct. They do not read the whole thing. If you are signing a contract that cheats you, or a power of attorney that gives away your house, the notary will notarize it anyway. Their role is only to confirm your identity and that you signed it yourself.

Documents that commonly need notarization

Real estate transactions almost always require notarized signatures—deeds, mortgages, and title transfers all need a notary's stamp. Powers of attorney, which let someone else make decisions for you, usually require notarization. Affidavits (sworn statements) need notarization. Some states require it for wills and living wills. Loan documents, especially for large amounts, often require notarized signatures.

Many other documents may need notarization depending on where they are going. If you are sending a document to another country, that country may require notarization. If you are submitting something to a court, the court rules will say whether notarization is required. When in doubt, ask the person or organization that is asking you to sign the document.

How to find a notary and what it costs

Notaries are available at banks, law offices, UPS stores, and some pharmacies. Many banks offer notarization free to customers. Some employers have a notary on staff. You can search online for "notary public near me" to find local options. Call ahead to confirm they are available and to ask about their fee, which typically ranges from $5 to $25 per signature.

You must bring the unsigned document and a valid government-issued ID. Some notaries will ask you to bring two forms of ID, though one is usually enough. You sign the document in front of the notary, they check your ID, and they stamp and sign the paper. The whole process usually takes five to ten minutes.

What notarization does not do

Notarization does not make a document legal. A notarized document is not automatically enforceable in court. It does not mean a lawyer has reviewed the document or that it is written correctly. It does not prove that the contents are true. If you notarize a statement that says you own a car but you do not, the notarization does not make it true—it only proves you signed the statement yourself.

Notarization also does not protect you from making a bad decision. If you sign a power of attorney that gives someone control of your bank account, notarization does not prevent them from taking your money. It only proves you signed it. If you are unsure about a document, talk to a lawyer before you sign it, not after.

Remote notarization and online options

Some states now allow remote notarization, where you sign a document on a video call with a notary instead of in person. The notary watches you sign on screen, verifies your ID, and sends you a digitally notarized copy. Remote notarization is faster if you cannot easily reach a notary in person, but not all states allow it yet, and not all documents can be notarized remotely. Check your state's notary laws or ask the organization requesting the notarization whether remote notarization is acceptable.

A few online services offer remote notarization, but they charge more than in-person notaries—often $50 to $100 per signature. In-person notarization at a bank or UPS store is usually cheaper and faster if you have one nearby.

Frequently Asked Questions

Can a notary notarize a document you already signed?

No. You must sign the document in front of the notary. If you signed it before you arrived, the notary cannot notarize it. You will need to get a blank copy and sign it again in the notary's presence.

What if I do not have a driver's license?

A passport, state ID card, or other government-issued photo ID works. Some notaries accept multiple forms of ID if one is expired. Call ahead and ask what ID the notary will accept.

Does notarization mean the document is legally binding?

No. Notarization only proves you signed it. Whether the document is legally binding depends on whether it was written correctly, whether both parties agreed to it, and whether it follows the law. A notarized contract is not automatically enforceable.

Can I notarize a document for a family member?

No. A notary cannot notarize a document for someone they are related to or live with, and they cannot notarize a document they have a financial interest in. This rule prevents conflicts of interest.

How long does a notarized document stay valid?

A notarized document does not expire. The notary's stamp and signature are a permanent record that you signed it on that date. However, the organization using the document may have its own rules—some banks or government agencies will not accept a notarized document if it is more than a few months old, even though the notarization itself does not expire.
