A: I would say that the best thing to do is that if you get sued by the car owner to counterclaim for defamation, and any other tings you might be able to think of.

A: Based solely on the facts presented, yes, with a caveat. That caveat being that there may be some privilege within the profession or recognized in the law that may absolve her of such liability.

There are 5 basic elements to a defamation claim; 1. a false statement, 2. about the Plaintiff, 3. published to a third party, 4. damage to reputation, (5. depending on the public figure/matter of public concern analysis, either, strict liability, negligence, or what is called actual malice). This can be a very complicated area of the law to argue and defend. It is best to talk to a local lawyer who has some experience
with this type of case.
A: In Indiana truth is an absolute defense to libel or slander, which I will call defamation.

A defamation case requires 4-5 elements; 1. a false statement, 2. about the plaintiff, 3. published to a third party, 4. damage to the plaintiff's reputation, (5. strict liability, negligence, or what is called actual malice.

Defamation is a complicated field of the law, and you should definitely speak to a local lawyer to whom you can
tell all the facts.
