Louisiana Revised Statutes Tit. 35, § 392.1. Ex officio notaries

A. Any person, not a regularly commissioned notary, who is an ex officio notary, or who is otherwise authorized under the various revised statutes and codes of this state to administer oaths or exercise any or all of the functions, powers, and authority of a notary, is authorized to perform those functions, powers, and authority only as they are directly related to and required for the operation of the office, agency, or department under which the authority is granted. All acts which are performed beyond the specific authority granted in the various statutes and codes of this state to administer oaths and to perform the functions, powers, and authority of a notary and which are not directly related to or required for the operation of the office, agency, or department shall be null and void.

B. The provisions of this Section shall not be applicable to documents notarized by a clerk of court or any of the deputy clerks of court who are employees of the clerk of court when such documents are notarized within the course and scope of their employment with the office of clerk of court. However, nothing in this Section shall prohibit such clerks and deputy clerks from notarizing vehicle titles or acknowledging the signatures on authentic acts even if such authentic acts are not within the course and scope of their employment.
