Notarizing a form: what it is and when it matters

A notary is a public witness. Their job is to verify the identity of the person signing and to witness the signature. Notarization does not make the document legal — it makes the signature verifiable.

When a form needs it

Some forms require notarization by state law; others do not. When a form says 'notarize this', it usually needs a witness who verifies your identity and signs a certificate. When it does not, signing is enough.

How to get it done

Notaries are common — many banks, post offices, law offices and libraries have one. Bring a valid photo ID, do not sign before the notary arrives, and check whether your state requires witnesses in addition to the notary.
