My question involves defamation in the state of: I own a property where I want to open a business. I can't start up the business because of financial problems, partner backing out, etc. I'm about to sell for cheap or lose the property. However, I have recently met with many potential partners who were about to sign a deal with me but were intercepted by a person who has inside information about my status and the property. I recently caught wind and have proof that this person finds out who I met and talks to them behind my back. Then blows the deal. (I believe he wants the business and property for himself)
Based on the small amount of facts I have given, do I have case against this person?
(Keep in mind that I have witnesses).
