Florida: Asking for a friend, If he and his ex-wife were married for five years, had a child and then divorced for financial reasons only and have stayed together for 11 years since the divorce. In the divorce agreement he was to pay child support each month. Since the home they live in is in his name only and he pays all the bills except for the phone bill which she pays, if he leaves her now can she claim that he never paid child support? Would he have to pay the back support even though he paid for everything over the past 11 years? He has no problem with paying from the time they separate now.
