I was a sole prop. and had offer by a family friend to buy in and incorp. I had 15,000.00 invested , a work truck, and large amount of equipment and tools . He said he would match money investment and buy a truck also. We went to a local attorney and he drew up incorp. papers, when he asked about share investment we told him we were still working on figures, so he drew up 1000 $1 shares and wrote that 100 were paid in. 1 year and alot of meetings and descussions later he hasn't come through with agreement. He has not invested one personal $ bill or one $'s worth of equipment or tools. He is now demanding i buy him out at $52,000.00. He quit coming to work and has started another job with a competitor. How do i go about buying the other 900 shares legally...HELP.
