Oaths of corporations

In all cases where a corporation is appointed administrator, executor, collector, or to any other fiduciary position, of which fiduciary an oath is required by law, such oath may be taken by such corporation by and through any officer or agent of said corporation who is authorized by law to verify pleadings in behalf of such corporation; and any oath so taken shall be valid as the oath of such corporation. Any oath heretofore taken in the manner aforesaid in behalf of a corporation as such fiduciary is hereby validated as the oath of such corporation.
