Legal Definition and Related Resources of Illegitimate

Meaning of Illegitimate

An illegitimate child is a child born of parents who are not legally married. If a child is born to a married woman, and is actually the offspring of her sexual intercourse with someone other than her husband, the law presumes that the child is legitimate as it is still the offspring of the woman who is legally married. The presumption can be rebutted by showing that the husband had no access to the wife at the probable time of conception . A child artificially conceived while the mother was lawfully married has been held to be a legitimate child. See People v Sorenson, 66 Cal. Rptr. 7, 437 P.2d 495, 68 C.ed280.
