Notarized means a notary public has verified your identity and watched you sign a document
When a document is notarized, it means a notary public — a person licensed by your state — has checked who you are, confirmed you are signing of your own free will, and then stamped and signed the document themselves. The notary does not check whether the document is true or fair. They only verify that you are who you say you are and that you actually signed it in front of them.
The notary's stamp and signature create an official record that the signing happened on a specific date, in front of a witness, and with a real person present. This matters because many institutions — banks, courts, government offices, title companies — will not accept certain documents unless they carry a notary's seal. The seal is proof that someone checked your ID before you signed.
Notarization is not the same as a lawyer reviewing your document or a court approving it. A notary is a neutral witness, not an advisor. They will not tell you whether you should sign something or whether it protects your interests.
Key Takeaways
- A notarized document has been signed in front of a notary public who checked your ID and watched you put your signature on the paper.
- The notary's job is to verify your identity and confirm you signed willingly — not to judge whether the document is fair or legally sound.
- Many financial, legal, and real estate transactions require notarized documents because institutions trust the notary's verification.
- Notarization costs between five and twenty dollars per signature, depending on your state and the notary's location.
- You can find notaries at banks, UPS stores, title companies, and online through your state's notary directory.
Why documents need to be notarized
Documents get notarized when the person or organization receiving them needs proof that the signer is real and actually agreed to sign. A bank might require a notarized power of attorney before letting someone else access your account. A court might require a notarized affidavit — a sworn statement — before it will consider your case. A title company will not transfer property without notarized deeds.
The reason is straightforward: notarization reduces fraud. If you forge someone else's signature on a document, you cannot also forge a notary's seal without committing a separate crime. The notary's presence and official record make it much harder to claim later that you never signed something, or that someone else signed your name without permission.
Some documents are notarized by law — wills, deeds, powers of attorney, and loan documents almost always require it. Others are notarized by choice, when the person asking for the document wants extra proof of authenticity. A landlord might ask for a notarized statement from a tenant about a lease dispute. A business might ask for a notarized signature on a contract.
What a notary actually checks
A notary will ask to see a government-issued photo ID — a driver's license, passport, or state ID card. They will compare the photo to your face and check that the ID has not expired. They will also ask your name and may ask what document you are signing and why, though they do not need to understand the details.
The notary watches you sign the document in front of them. They do not sign it for you or let you sign it ahead of time and bring it in. You must be present and sign while they are watching. Some notaries will ask you to initial each page or to sign in a specific place on the document.
After you sign, the notary adds their own signature, the date, their notary number, and an official seal — usually a stamp or embosser that leaves a raised mark on the paper. Different states have different seal requirements, but all notary seals are designed to be hard to copy.
What a notary will not do
A notary will not read your document carefully or tell you whether it is a good idea to sign it. They will not check whether the terms are fair, whether you understand what you are agreeing to, or whether the other person is being honest. They are not lawyers and cannot give legal information.
A notary will not notarize a blank document or one with blank spaces you plan to fill in later. They will not notarize a document you did not write or that someone else is signing on your behalf. They will not notarize a document if you appear confused, intoxicated, or unwilling to sign.
A notary also will not notarize a document if your ID is expired, if you cannot prove your identity, or if the document itself is illegal — for example, a notary in most states will refuse to notarize a document that appears to be forged or that asks them to help with fraud.
Where to find a notary and what it costs
Notaries work at banks, credit unions, UPS stores, FedEx locations, and title companies. Many law offices and real estate offices have notaries on staff. Some libraries and government offices offer notary services, sometimes free to residents. You can search your state's notary directory online — most states maintain a list of licensed notaries by county.
The cost varies by state. Most notaries charge between five and twenty dollars per signature. Some charge a flat fee per document instead. Banks often notarize documents free for customers. Online notaries — who verify your identity through video and email you a notarized document — typically charge fifteen to fifty dollars and take one to three business days.
Before you go to a notary, make sure you have the unsigned document with you, a valid government-issued photo ID, and cash or a card to pay the fee. Call ahead if you are going to a bank or office, because some notaries are available only at certain times or by appointment.
Remote notarization and electronic documents
Some states now allow remote notarization, where a notary verifies your identity through a video call instead of in person. You upload a photo of your ID, the notary watches you sign the document on screen, and they send you a notarized PDF by email. This is faster than visiting a notary in person, but not all documents can be notarized remotely — some states limit it to certain types of paperwork, and some institutions still require an in-person notary seal.
Electronic notarization — where the notary's seal and signature are digital rather than stamped on paper — is also becoming more common. Many courts and government offices now accept electronic notarized documents. However, some older institutions and some states still require a physical seal on paper, so check with whoever is asking for the notarized document before you choose remote or electronic notarization.
Common documents that need notarization
Wills and trusts almost always need notarization, though the rules vary by state. Powers of attorney — documents that let someone else make decisions on your behalf — require notarization in most states. Deeds, mortgages, and other real estate documents must be notarized before they can be recorded with the county.
Affidavits — sworn statements used in court — need notarization. Loan documents, including personal loans and car loans, usually require notarized signatures. Some employers ask for notarized statements about your background or work history. Immigration documents, passport applications, and some government forms also require notarization.
If you are unsure whether a document needs notarization, check the document itself — it will usually say "notary public" or "notarization required" somewhere on the page. If the document does not say, ask the person or organization asking for it.
Frequently Asked Questions
Can a notary notarize a document I did not write myself?
No. A notary will only notarize a document you are signing. They will not notarize a document someone else signed, and they will not notarize a blank form you plan to fill in later. The document must be complete and ready to sign when you arrive.
What happens if I lose a notarized document?
You can ask the notary to issue a certified copy if they kept a record of the notarization. Many notaries keep a journal with details of every document they notarized. If the original notary is no longer in business, you may need to have the document notarized again by a different notary, or contact whoever issued the original document to ask for a copy.
Can I notarize a document for a family member?
No. A notary cannot notarize a document for someone they are related to or have a financial interest in. This is a conflict of interest. You will need to find a different notary who has no connection to you or the document.
Does notarization mean the document is legal?
No. Notarization only proves that you signed the document in front of a notary and that your ID was checked. It does not mean the document is legally valid, properly written, or fair to all parties. A lawyer should review important documents before you sign them.
How long does a notarized document stay valid?
Most notarized documents do not expire. However, some institutions set their own rules — for example, a bank might accept a notarized power of attorney for only five years. Check with whoever is asking for the notarized document to learn about there is a time limit.
