According to the civil law, which generally regulates the administration of personalty, it is held that when parent, whether father[593] or mother,[594] and child perish together, as in shipwreck, if the child be of the age of puberty, he shall be presumed to have survived; but on the contrary that he died first if he were under that age: regard being also had to the relation of the party who is to benefit by the decision. (_Domat C. L. p._ 652, 653.) But “it may happen several ways, that the mother may perish under the ruins of a building sooner than the child whom she suckles. It may happen that a son may be killed in a battel before his father; and on the same occasions, and likewise on all others, it may so fall out, that they both die in the _same_[595] instant, or that even he who by reason of his age, or some other infirmity, might be presumed to die first does nevertheless die the last.” (_Domat._ 651). By the _Code Napoleon, Art._ 721, 722, it is laid down that, of persons under fifteen, the eldest shall be presumed to have survived, above sixty the youngest; if some were under fifteen and others above sixty, the former are presumed to have survived; of persons between fifteen and sixty, males are presumed to have survived, the ages being equal or where the difference does not exceed one year. The order of nature appears to afford the best general rule, and therefore, in the absence of all evidence to the contrary, it is to be wished that it were established, that the natural succession had taken place, as if no accident had occurred; that the child survived the parent; the nephew, the uncle; descendants, asscendants; legatees, testators; and generally that the younger had outlived the elder. The decision in the following curious case appears to have been directed in conformity with such a principle. A father and son having perished at the battle of the Dunes, fought near Dunkirk in 1658, and the daughter and sister having at noon, on the very same day and hour, taken the vows in a nunnery, whereby she became _dead in law_[596], a question arose as to survivorship among these three persons, when it was decided that the Nun died first, since her death, being voluntary, was consummated in a moment; whereas that of the father and son, being violent, was probably not immediate. Between the father and son there did not appear to be any data for a just conclusion, and it was therefore decreed, according to the established rule above stated, that the son had survived the father.
