Recently I received checks for my pension plan from a place of previous employment. I was confused because I was not there long enough to be fully vested, so I called the mutual company and they said that in their contract it said nothing about being vested and that the money was mine. I even called back on another day to ask someone else, and they said the same thing. So I cashed the checks. The checks were written out to myself and our shop steward, only I signed them, but the bank cashed them anyway. Now my previous employer is trying to get the money back. Do you know if I will have to give the money back? Any information would be greatly appreciated.
