I don't think your roommate is being malicious. He probably told his dad about the project and his dad being the lawyer that he is, said "hey, have him sign this contract." And because it was a 17 page contract, your friend didn't even read it. I would have an open & honest conversation with him about what your vision is for the software and what expectations you have for compensation, including equity. If you can't have this discussion, walk away. It's a good indicator that you two won't be able to work out tougher problems in the future. PS: This conversation doesn't have to be a tense situation. In fact, if you are excited about the future of this software, communicate it and maybe he'll catch the fever.
