A "natural" child; a child begotten and born out of wedlock; an illegitimate child; one born of an illicit union. Note: By the civil and canon laws, and by the laws of many of the United States, a bastard becomes a legitimate child by the intermarriage of the parents at any subsequent time. But by those of England, and of some states of the United States, a child, to be legitimate, must at least be born after the lawful marriage.
