Must children residing with their divorced mother, who manages their affairs due to their father's insufficient financial support, seek their father's permission before going out or traveling, knowing that one of them is 17 years old?

If the son reaches puberty and has a wet dream, he may go wherever he wishes without his father's permission, except that it is commendable for him to seek permission as a form of dutifulness. He must seek permission for travel in which harm or peril is feared, or if his father is in need of him and fears destitution after his departure.
