<p>In all states where support stops at 18 (most) neither parent is required to pay a dime for college. I'm not so sure they are in states where the age is 18 either.</p>
<p>Also, if a father has money to jet set and the mother and children are in a ratty apartment, they have every right to go after him for additional funds unless the mother waived her rights at the time of divorce, and no one does that who doesn't have their own assets to protect. They can get funds out of his pay from his employer and even get his tax returns. It's hard for the wealthy to be deadbeat dads.</p>
<p>For the family to slip him under the rug, they would have to prove that he had not paid child support for some time and that the child did not see him.</p>
