Although I came up with the idea and created the initial site, I'm getting some feedback from someone about my website's strategy, implementation, and business idea. He claims not to want the financial side of it, but I'm afraid if my site takes off, he will try to claim that he is owed something (I've heard of this happening before).
What kind of easy legal document can I have him sign to put this in writing? Would an email confirming it be enough?
