My husband left 5 years ago, we never filed for divorce or separation, I never see him, we have a son and a child support case was opened in 2005 by the welfare office (he left us with nothing) listing me as the custodial parent, we never went to court for custody or visitation either. He does not see my son and my son knows him by name only. He is 6 years old now. I want to move out of state to better our lives, but I thought I'd have to file for divorce and custody first. Does me being listed as the custodial parent mean that I already have sole custody? Do I even need to file for custody?
