I was approached to help with a business venture. The idea fulfills a particular niche market. We do not have a partnership agreement. In fact we haven't signed anything. The problem is that these people have been doing nothing but talk. Half a business plan has been drafted, but is collecting dust on someone's desk. I think the idea is very lucrative and has the potential of being very profitable. I do not want this idea to go to waste. Will I be liable if, assuming I can get the start up capital, I do this without them even though I wasn't the original "idea man"?
