What a notary does and why documents need one
A notary watches you sign a document and confirms that you are who you say you are. They do not read the document, judge whether it is fair, or check whether you understand what you are signing. They verify three things: your identity (usually through a driver's license or passport), that you are signing of your own will without pressure, and that you are aware you are signing. Then they stamp the document and sign it themselves.
Documents get notarized because a third party — a bank, a court, a government agency, or a business — wants proof that the signature is real and that the person who signed it actually intended to. A notary's stamp carries legal weight because notaries are licensed by the state and can lose that license if they break the rules. When a document says "notarized," it means someone official watched the signing happen.
Key Takeaways
- Real estate transactions, power of attorney documents, and affidavits almost always require notarization because money or legal authority is involved.
- Banks, courts, and government agencies often demand notarized copies of documents like birth certificates or marriage licenses before they will process them.
- A notary cannot notarize a document you sign in front of them without your physical presence — remote notarization exists in some states but requires specific technology and advance notice.
- You can find notaries at banks, UPS stores, law offices, and county clerk offices; fees typically range from five to fifteen dollars per signature.
- Not every signature needs a notary — personal contracts, rental agreements between you and a landlord, and most everyday documents do not require one.
Real estate and property documents that require notarization
Deeds, mortgages, and property transfer documents must be notarized in every state. When you buy or sell a house, the deed — the document that proves who owns the property — gets notarized because the government needs to know the transfer actually happened and that both parties agreed to it. A mortgage note, which is your promise to repay the loan, also gets notarized because the bank needs proof you signed it yourself.
If you are refinancing a mortgage or taking out a home equity line of credit, the lender will require notarization. Power of attorney documents that give someone else the right to handle your property or finances must be notarized in most states. Affidavits about property — for example, a sworn statement that you have lived in a house for a certain number of years — also need a notary's seal.
Financial and legal documents that commonly need notarization
A power of attorney document, which gives another person the legal right to act on your behalf, must be notarized in most states. This applies whether the power of attorney covers healthcare decisions, financial decisions, or both. Wills and trusts do not always require notarization, but many people have them notarized anyway to make them harder to challenge later.
Affidavits — sworn statements you make under penalty of perjury — need a notary's signature. These come up in court cases, loan applications, and immigration paperwork. If you are explore for a loan and the lender asks for a notarized copy of your birth certificate, marriage license, or divorce decree, you will need to bring the original document to a notary, who will compare it to your ID and then stamp a copy as a true copy of the original.
Government and court documents that require notarization
Immigration paperwork often requires notarized documents. If you are explore for a visa, green card, or citizenship, you may need to submit notarized copies of birth certificates, marriage licenses, or other vital records. Court filings in some cases require notarized affidavits. If you are filing a motion or a response in a lawsuit, the court may require that your signature be notarized.
Certain government benefits applications ask for notarized documents. Some states require notarized copies of documents when you explore for a business license or register a business name. If you are explore for a passport or renewing one, you may need a notarized statement or a notarized copy of a birth certificate, depending on your age and the type of process.
Documents that do not need notarization
Personal contracts between you and another individual — like a loan agreement with a friend or a roommate contract — do not require notarization unless a third party (like a bank or a court) demands it. Rental agreements between a tenant and a landlord do not need to be notarized in most states, though some landlords request it. Employment contracts, service agreements, and purchase agreements for items like cars or furniture do not require notarization unless the seller or buyer specifically asks for it.
Letters of recommendation, personal references, and most everyday documents do not need a notary. Emails, text messages, and digital documents you create yourself do not need notarization. A document you sign in front of witnesses but without a notary is not notarized, even if the witnesses sign it too — a notary is a specific legal role, not just any third party.
Where to find a notary and what to bring
Banks often offer notary services to customers for free or a small fee. UPS stores, FedEx Office locations, and some CVS and Walgreens pharmacies have notaries on staff. Law offices, title companies, and real estate offices have notaries. Your county clerk's office or courthouse can direct you to a notary or may have one available.
Bring a valid photo ID — a driver's license, passport, or state ID card. Bring the original document you need notarized. If you are asking for a notarized copy of a document (like a birth certificate), bring both the original and blank copies. Some notaries charge per signature, not per document, so if a document has multiple signature lines, you may pay multiple times. Fees typically range from five to fifteen dollars per signature, though some banks waive the fee for customers.
What happens if you sign something without a notary when one was required
If a document required notarization and you signed it without one, the document may not be accepted by the bank, court, or government agency that asked for it. You will have to get it notarized later. If the document was a deed or a mortgage, the transaction may not be recorded properly, which can create problems if you try to sell the property later or if there is a dispute about who owns it.
If you signed a power of attorney without notarization when your state requires it, the person you named may not be able to act on your behalf. Courts and government agencies will reject unnotarized documents that they specifically asked to be notarized. The solution is to go back to a notary with the original document and your ID and have it notarized then. You do not have to sign it again — the notary will notarize your existing signature if you confirm in front of them that you signed it.
Frequently Asked Questions
Can a notary notarize a document I signed before I met with them?
No. A notary must watch you sign the document or must confirm that you signed it in front of them. If you signed it weeks ago and bring it to a notary now, they cannot notarize it. You will have to sign it again in front of the notary. The notary will then stamp and sign the document to confirm they watched you sign it.
Do I need a notary if I am buying something from a private person?
Not unless the buyer or seller asks for one or unless the item is real property (land or a house). A bill of sale for a car, boat, or other item does not legally require notarization in most states, though some buyers request it for protection. If the seller asks for a notarized bill of sale, you will need to visit a notary together or separately with copies of your IDs.
Can I notarize a document online or by video?
Some states allow remote notarization through video, but it is not available everywhere and usually requires advance scheduling. The notary will watch you on video, confirm your identity through your ID, and then email you a notarized copy. Not all documents can be notarized remotely — real estate deeds and some government documents may require in-person notarization. Check your state's rules or ask the organization requesting the notarized document whether remote notarization is acceptable.
What if I cannot get to a notary in person?
If your state allows remote notarization, you can schedule a video appointment with a notary. Some notaries also travel to your home or office for a higher fee. If neither option works, you can ask the person or organization requesting the notarized document whether they will accept an alternative — for example, a certified copy from a government office instead of a notarized copy.
How long does a notarized document stay valid?
A notarized document does not expire. The notary's stamp and signature prove that the notarization happened on a specific date, but the document itself remains valid unless the law or the organization using it says otherwise. Some organizations ask for documents notarized within a certain time period — for example, a bank might ask for a notarized affidavit dated within the last 30 days — but that is their requirement, not a rule about notarization itself.
