I am in Indiana. My ex hasn't seen the kids in three years partially because our case is assigned in Arizona and he won't sign the paperwork to have it changed to Indiana and he has supervised visitation per the special master in our case whom since he was assigned has resigned for safety reasons... hes afraid of my ex husband. My ex hasn't seen nor asked to see the kids in a year and a half. Is that abondonment? How do I go about filing paperwork on that?
