I've been working with my partner for a few months on our project, and each of us has put in a lot of work, and we share the IP, in the sense that we've been collaborating all along.
We haven't formed a corporation yet, so any division of equity is on a handshake right now. We've agreed over email, but haven't written anything on paper and signed it.
Is there any way to protect myself and the contributions I've made so far? I'm specifically looking for examples of boilerplate agreements that we could both sign which would be enforceable later when the corporation is formed. Basically a pre-nup for partners.
If one of us does walk away, what happens to the contributions we've made? Can the other person still use that IP?
