Only one body is admitted in each coffin. However, the interment in the same coffin of the bodies is authorised:
1° Of several stillborn children of the same mother or children born alive and then deceased after childbirth;
2° Of the mother and one or more of her stillborn children or children born alive and then deceased after childbirth.
The 1° and 2° apply only if the first death occurs at the latest at the time of childbirth or shortly thereafter and the last death occurs before the end of the legal period for burial or cremation following the first death.
