I found out mom co-signed a car loan for a felon 6 months ago he defaulted. I have POA told her to not give him any money and not to sign anything without my approval. She did this without my approval and he knew I would not approve and convinced her to do it anyway. He is now back in jail on parole violations. Doesn't this constitute elderly abuse and can I file charges? And are the people who financed this liable as she is obvious that she is confused?
