Lawyer. Lawyer lawyer lawyer. This is the only answer. You don't need to go in guns blazing, but you do need good legal counsel even before you talk to your business partner. A lawyer will be able to tell you your rights, what you don't have rights to (even more important), and the probable result of various courses of action. You will also have much more confidence when it comes time to have the discussion, because you have gotten help and will understand the situation a lot more clearly. Seriously: GET. A. LAWYER.
