If your grandparents did not get legal custody/guardianship when you went to live with them, then I am not sure anything can be done now if you are 18 or older. I agree with whoever said you need to talk to an attorney. Indiana has come along way with child welfare issues. I know of a couple who divorced and child went to live with grandparents. The grandparents are getting the child support. Parent will have to pay for college, not grandparents. If your mother is covering you with insurance, you are very blessed. if your are eighteen and if you did not go to college within 12 months of graduating, I do not think you can get any money now. (you would be considered emancipated) You can always sue some one for something, if you can pay the attorney's fees, does not mean you will win. Also, if you are unable to cover copays/medicine, you need to check into Ithe Healthy Indiana Plan (HIP) program or Medicaid. You may not be eligible since your mother has you on her insurance, but check it out anyway. Good luck! Sometimes it is better to choose your own family, and let your "real family" go. I have found that I am better off without some of my family members whose sole purpose in life was to make me feel I was lucky to hear their harsh judgemental opinions on my life choices. Life is to short for that junk, IMHO!
