Question 1744) - Why have you stipulated "minor"?

A: The father is not responsible for maintaining adult male children because they are able to earn for themselves, unless the adult son is chronically adult, in which case the father is responsible for two-thirds of his maintenance and the mother is responsible for a third. The parents are also responsible for the unmarried daughter in the same proportion. They are only responsible for the adult chronically ill son and adult unmarried daughter if they are Muslims.
