I'm in Atlanta, Georgia. I was wanting to find out how my father can get guardianship of 2 children. The children were adopted by my father's girlfriend of 7 years. She died last year and no family member has temporary or legal custody of the children. The children are still living with my father and I believe his girlfriend's sister is getting the social security checks and telling my father also. No one else is taking responsibility for the children. I need to know what steps he can take to get guardianship.
