My father died and had a friend on his checking account he thought they could get money for him in case of emergency. I went to the bank and they said she was a co owner when i talked to her she said she took the money out and if he wanted me to have he would have given it to me. Well he did in a will and i have been to probate now she said she needs the money to live on because she only gets ss of 850.00 she wasn't a girlfriend and rarely came around.
To be successful in a lawsuit or criminal prosecution, you would have to prove that dad was somehow coerced into putting her name on the account. You aren't going to be able to prove that.
Forget it.
