The authentic act of the consent of the father and mother or grandparents or, in their absence, that of the family council, shall contain the forenames, surnames, occupations and domicile of the future spouses and of all those who have contributed to the act, as well as their degree of kinship.
Except in the case provided for by article 159 of the Civil Code, this act of consent is drawn up either by a notary or by the civil registrar of the place of domicile or residence of the ascendant, and, abroad, by French diplomatic or consular agents. Where it is drawn up by a civil registrar, it must be legalised, unless there are international agreements to the contrary, only when it is to be produced before the foreign authorities.
