Someone I thought of as a business partner said he filed us a 501 (3)(c) for our organization, turns out he didn't and as of lately disappeared. We haven't received donations but a similar organization is claiming we are using their name and idea (we weren't) and are saying they will prosecute me for fraud among other things. Not being able to get into contact with my shady partner I have stopped all efforts and taken down all websites nearly a week before this happened and now today I was informed by the similar company if I do not do as they ask they will prosecute me, is this even possible? Should I lawyer up for harassment or should I follow their demands? Either way the organization we were starting is now out the window, I just want to know if they are just yanking my chain with a scare tactic or what to do.
