So you sold half the accounts to Turd1, and half to Turd2. Sold the equipment to Turd 3. TurdX wants all 12 accounts, the 6 he bought and the 6 TurdY bought. OR You sold 12 accounts to Turd1 and sold the equipment to Turd3 and Turd 1 and 2 above are with the same company and you lumped them together. Either way a client isn't property and sale of a client's contract and the service it entails shouldn't be on the table until the client agrees to use the person you are selling to or agrees to use the person buying. I wouldn't pay for 12 accounts until the 12 accounts agreed to use me.
