My ex was ordered to pay for my sons health care. He figured since I had to pay for the family plan for my other son (who is not his) thenhe would just quit his job. That fully paid family health care. I have asked him several times to put my son back on his health care and he refuses. Can I sue him for all the years I have been paying it. Also my son is now 18 can he still go back on my ex's plan?
