Authentication of authority of officer.
(a) If the notarial act is performed by any of the persons described
in paragraphs 1 to 4, inclusive of Section 2, other than a person
authorized to perform notarial acts by the laws or regulations of a foreign
country, the signature, rank, or title and serial number, if any, of the
person are sufficient proof of the authority of a holder of that rank or
title to perform the act. Further proof of his authority is not required.
(b) If the notarial act is performed by a person authorized by the laws
or regulations of a foreign country to perform the act, there is sufficient
proof of the authority of that person to act if:
(1) either a foreign service officer of the United
States resident in the country in which the act is performed or a diplomatic or consular officer of the foreign country resident in the United States certifies that a person holding that office is authorized to perform the act;
(2) the official seal of the person performing the
notarial act is affixed to the document; or
(3) the title and indication of authority to perform
notarial acts of the person appears either in a digest of foreign law or in a list customarily used as a source of such information.
(c) If the notarial act is performed by a person other than one
described in subsections (a) and (b), there is sufficient proof of the
authority of that person to act if the clerk of a court of record in the
place in which the notarial act is performed certifies to the official
character of that person and to his authority to perform the notarial act.
(d) The signature and title of the person performing the act are prima
facie evidence that he is a person with the designated title and that the
signature is genuine.
