I started a company (corporation) a year ago. Initially, a family friend helped me with the investment. He deposited some money into my business account and made charges for my business on his personal credit card. He also worked for the business and get paid. Anyhow, all his investment had been paid. Now, he opens his own company and wants me to pay him 50% of the profit. Am I entitled to pay him? We never had any written contract and I'm the only managing member when the corporation was incorporated.
