(M392) Adoption primarily means a process by which parents could admit to the privileges of sonship children born of other parents. There were many reasons which might impel them to such a course. If they were childless, a natural desire for an heir might operate. But under the Babylonian law a man might take a second wife, or a maid, if his wife were childless, to bear him children. A more operative cause was that children were a source of profit to their parents while they remained with them. But it seems that men married early. Hence this alone does not seem sufficient to account for the great frequency of adoption. Besides, in that case, what induced a parent to part with his child for adoption? It seems that the real cause most often was that the adopting parents had lost by marriage all their own children and were left with no child to look after them. They then adopted a child whose parents would be glad to see him provided for, to look after them until they died, leaving him the property they had left after portioning their own children. (M393) The Code admits all kinds of adoption, but regulates the custom. A man might adopt an illegitimate son, or the child of a votary or palace-warder, who had no right to children, or the child of living parents. In the latter case alone was the parents’ consent necessary. We have examples of cases of adoption of relatives, of entirely unrelated persons, of a slave even.(373) We learn from the series _ana ittišu_(374) that a man might take a young child, put it out to nurse, provide the nurse with food, oil for anointing, and clothing, for a space of three years; and then have it taught a trade or profession, such as that of scribe.(375) (M394) Adoption was effected by a deed, drawn up and sealed by the adoptive parents, duly sworn to and witnessed. Such contracts definitely state the relationship, which was in all respects the same as that of a son born in matrimony. But it laid down the obligations of the son, while it stipulated what was the inheritance to which he might expect to succeed. It brought responsibilities to both parties and fixed them. The son was bound to do that which a son would naturally have done, explicitly, to maintain his parents while they lived. The parents were bound, not only to leave him property, but to treat him as a son. But, as a rule, all was matter of contract and carefully set down. If such a contract was not drawn up, although the adoptive parents had brought him up, the child must return to his father’s house.(376) Only, for an artisan, it was sufficient to have taught the child his trade.(377)
