My brother had a son by a lady, that died 4years ago, her sister has guardenship, because the mother had the baby in prison( brother didn't know about the baby then). The mother got out jail got herself together, and the kid moved back in with the mother. Mother never got guardenship back from sister, mother died four years ago.The sister took the boy from step father that was married to the mom( not my brother) Since then the child was taken from the aunt because of abuse and drugs, I had temporary guardianship, until the aunt finished her drug program, then the child was placed back with the aunt.The aunt isn't able to care for the child, and I witnessed where the aunt is very verbally abusive to the child, the child is afraid of the aunt ,want can I do to get custody and adopt the child?
