My husband has 3 kids from a prior marriage . One is 20 , one is 18 next month and one is 14 . But we still pay support for 3 kids . Shouldn't support end when they turn 19 whether or not they are in college . Although he agreed to pay 50 / 50 for college , neither parent can afford this so the kids are actually having to get student loans . His ex is threatening him stating that he will have to continue to pay support until the kids are 26 . . . I am not quite sure where she is getting that .
