In a proceeding to open the succession of a person presumed dead, as provided in R.S. 9:1441, or in any other action or proceeding whatever in which the presumption of his death is an issue, this presumption may be proved by a certified copy of an official certificate of the armed service to which he was attached, or of pertinent excerpts from his service record, indicating that the armed service has accepted the presumption of his death.
