You can sue, but whether or not you win is a different story entirely. Defamation cases are extremely expensive to pursue. One of the more difficult aspects is proving your damages. Lost sleep is not enough. How was the alleged defamatory information provided to third parties? If you have not done so already, you should make a copy of the publications or if a computer post, screen shot the posts.
You can "sue" for just about anything. Prevailing is another story. In my 9 years of practice I have never seen a slander claim prevailed upon in Family Court. Most often it is a claim that perturbs the judge and is seen as a vexatious litigant.
Before bringing a claim, one needs to understand the requirements. Here is a bird's eye view of defamation (specifically, slander and libel).
Defamatory language—(i) language diminishing respect, esteem, or goodwill toward P, (ii) of or concerning P (reasonable 3rd party believes language refers to particular P, (iii) publication—intentional or negligent communication to 3rd party, and (iv) Falsity (public concern).
Libel – written, printed or otherwise recorded in permanent form; general damages that compensate P for harm to reputation
Slander – spoken word, gesture, or any form other than libel; special damages required; 3rd party heard comments and acted adversely to P; usually, but not always, economic loss
This is the common law. It will likely vary in Nevada. Contact a local lawyer.
