help needed

As long as you have proof of contract, such as e-mail stating the facts of the deal and it comes from his e-mail account that would be useable in a court of law. Have them sigh something stating fact and have it notorized and send you a hard copy. Dont know if that helps. Are we talking big $$$$$$$.
In the end if someone wants to rip you off they will, and even with all the paperwork in the world if they dont have anything or any money good luck with the restitution. Been there, it was alot of very stressfull and angry times. :angry7:
Good luck in what ever happens Chad.
