Most people are familiar with the famous opening line of the Miranda warning that police read during an arrest: "You have the right to remain silent. Anything you say or do can and will be used against you..." While no such warning is given to spouses approaching divorce, if a warning was given, it would probably state: "You have the right to remain silent. Anything you post on Facebook or other social networking websites can and will be used against you in a court of family law."
