I would guess that binder contains some Stock Share Certificates. They should be given out to the shareholders and that would determine the ownership. I HATE S-CORPS. It sounds like you are encountering the same type of S-Corp I have met my whole career. Mikey at the Barber shop mention what a great thing the S-Corp is so everyone at the bar went home and did some research with the cab driver on the way home. They all ran out and set up this mess they could done more gooder by getting a good insurance agent to buy some liability policy for themselves.  I HATE S-CORPS.
