My sister had guardianship of my 17 yr old. I found out yesterday that she signed over guardianship back over to the state and she is now living in a foster home with her 3 yr old daughter. I was told by friends that she don't have to stay there if she didn't want to, and that I could go get her and there's nothing anyone can do. Would I get in trouble for kidnapping my own daughter, and grand-daughter, and would she get into trouble for leaving?
