Can I sure for more even after a divorce settlement because of lies of x spouse

It depends upon (a) whether you knew of the lies during the divorce or only learned of them after the divorce was final and (b) how long it has been since your divorce decree was entered.  Check Rule 60.2 of the Tennessee Rules of Civil Procedure for the grounds and time periods for reopening a divorce due to newly found evidence, etc.  Cathy Naugle, Boise, Idaho family law attorney merrisnaugle.com
