If one was to marry another woman without consulting his first wife, and then begets a child from the secretly married woman is the begotten child an illegitimate child? Must the children of the first wife have any relationship with her or should they disown her as a sibling?
An illegitimate child is not the case of a child born in a lawful marriage. Recognition from half siblings is immaterial but good relations are a blessing.
