(Lit., a bastard.) According to Jewish law, a child born of a mother who is married to someone else is a mamzer. A child born out of wedlock is not a mamzer and is, in fact, no different from any other child. The issue of mamzer is a complicating factor in the question of divorce. If a woman who is refused a get – a writ of divorce by her husband – or who never receives a get – remarries and gives birth to children, those children are mamzerim.

(MAHM-zer) Lit. bastard. The child of a marriage that is prohibited and invalid under Jewish law, such as an incestuous union.

Mamzer (Hebrew: ממזר) in Halakha (Jewish religious law) is a person born of certain illegitimate relationships between two Jews. That is, one who is born from a married woman as a product of adultery or someone born as a product of incest between certain close relatives. The mamzer status is inherited by children; a child of a mamzer (whether mother or father) is also a mamzer.
