A notary, or notary public, is a public official authorized to witness the signing of important documents and verify the identities of the signers. Their primary role is to prevent fraud by ensuring that individuals are signing documents willingly and are aware of the contents. Notaries often handle documents like wills, contracts, and deeds. In addition to witnessing signatures, notaries may also administer oaths and affirmations. They are required to keep a record of their notarial acts, which can be important for legal purposes. Notaries are typically appointed by state governments and must adhere to specific laws and regulations.
