A notary public is an official witness who verifies your identity and watches you sign a document, to help prevent fraud. You'll need one for things like certain affidavits, property paperwork, and some legal forms. Banks, shipping stores, and libraries often have one.
What a notary actually does
A notary checks your ID, confirms you're signing willingly, and stamps/seals the document as proof. They don't give legal advice or vouch for the contents — just that you are who you say you are and you signed it.
In most states a will needs witnesses, not just a notary — notarization usually creates a separate "self-proving" affidavit. A notarized but unwitnessed will can be invalid, and nobody finds out until it's too late to fix. Rules differ in every state, so follow your attorney's or service's signing instructions exactly.
Where to find one
- Your bank or credit union (often free for members).
- Shipping and print stores (UPS Store, etc.).
- Libraries, courthouses, and some real-estate or law offices.
- Online notaries for remote signing, where allowed.
A valid government photo ID, the unsigned document (don't sign it ahead — they need to watch you sign), and any other signers who are required.
Common questions
How much does it cost?
Often a few dollars per signature, and sometimes free at your bank. Online notarization may cost a bit more for the convenience.
