I am trying to get my child support reduced.I am currently paying for 2 children my son who is 19 is still in school.my daughter is 20 finished school and working fulltime.My ex agrees i shouldnt be paying for my daughter.We both sent forms to FRO stating this the problem is in the wording of my support agreement it say,s global. Fro tells me i need to file a 15a form the courts tell me i need to file a 15d form and my lawyer told me i need to file a form 15.Anybody had this problem and which form did you file.
