Article 77
In any case in which the donor has vested the administration in two or more persons independently, when one of them deceases, the other or others take possession individually and if it be laid down that such taking possession shall be collective, then an act of taking possession on the part of anyone of the administrators shall not be valid unless it has the approval of the other or others, and after the death of one of them the judge shall appoint a person to be added to the survivors in order that they may jointly enter into possession.
