My lawyers want me to remind you that I'm not a lawyer and that I'm completely unqualified to offer legal advice. This site is meant to serve as a reference for you on your journey. If you have questions or concerns, please contact a qualified lawyer (or accountant) to help you. Also, as a general rule, never take random legal advice on the internet.
