A neighbor has been telling horrible lies about me and I want to sue her. What are the most damages I can recover against her?
Tennessee law has no limit on the amount of damages you can recover. The jury (or judge, or if jury is requested) sets the amount of the damages based on the amount of harm you have suffered.
Of course, there is always the practical problem of being able to collect the damages you win. But there is no damage cap imposed on jury awards in slander cases.
