Is the husband religiously obligated to cover his wife's expensive university tuition fees, and is the father entitled to refuse to financially support her studies after marriage?

A husband is not obligated to spend on his wife's university education. Rather, the obligatory spousal maintenance is a sufficient amount for food, housing, and clothing, according to what is customary. Likewise, a father is not obligated to spend on his daughter's university education, whether she is married or not.
