I worked for a international start up company. I had no ownership in this company and it has since gone out of business. An investor in the company is suing the company, and the ceo to recover a lost investment. The investor subpeoned the bank records and saw I was paid some money and is now suing me for this money. I don't have any money to defend myself and almost think this is harrassement and or frivolous. What are my options?
