Legal Question in Civil Litigation in North Carolina

You should be very careful in this situation. You are correct that no contact should occur, even in letter form. Depending on the language you use, it could be argued that you transmitted a threat in your letter.

You should speak to each person that this person spoke to and see if they are willing to give you a statement as to what was said. From there, if you can show that those statements are false and that the person knew they were false, you should contact an attorney that handles personal injury/torts for a potential slander claim.
