Hi, My name is XXXXX XXXXX I’m happy to assist you with your question today.
Your procedure to collect the debt would be to file a breach of contract
claim in the Justice of Peace Court in your jurisdiction. At this website
you can find model complaints that you can use to file your claim. After you have that filed and have served the debtor, he'll have 15 days to file an answer. After the answer is filed a trial date will be issued at which time you can prove to the judge that the debt is owed and get a judgment.
With regard to the claims of libel and slander, these would have to filed separately in a court of common jurisdiction and are significantly more difficult to prove. Specifically, you'd first have to send a cease and desist
letter and demand a retraction of these statements. You'd have to be able to allege and prove that the person intentionally misrepresented facts to these people, with the intention to defame your character and cause interference with your job/life that caused you financial and emotional distress as a result. Opinion statements are an absolute defense to these matters, which makes these cases difficult to prove because you have to prove the person made a "factual" (as opposed to opinion) and inaccurate statement intentionally with the intent to harm you. It's difficult to prove that. But if they refuse to retract them and you are harmed as a result it is your only recourse.
