The Code of Hammurabi

If a man, after a young child whom he has taken to his sonship and brought him up, has made a house for himself and acquired children, and has set his face to cut off the nursling, that child shall not go his way, the father that brought him up shall give to him from his goods one-third of his sonship, and he shall go off; from field, garden, and house he shall not give him.
