In Missouri, a notary public is an officer appointed by the Missouri Secretary of State. Commissioned notaries have statewide authority to attest to the authenticity of a person's signature, to administer oaths, to take affidavits and to perform other legal acts.  Please refer to the Missouri Notary Public Handbook for complete details.

Notarization on a document certifies that the person named on it appeared before the notary, displayed valid identification and signed the document in the notary's presence.
