Good afternoon. I am Loren, a Florida licensed attorney, and I look forward to assisting you. I am sorry to hear of your dilemma. I realize how frustrating this is for you and I hope to provide you information which is accurate and useful, even though it may not be the news you were hoping to get.
Unfortunately, the landlord has no legal obligation to renew your lease. The only limitation is that they can not take action against you or refuse to renew based upon race, religion, ethnicity, etc., as that violates the Fair Housing Act.
If the neighbor is intentionally making false factual allegations against you you may be able to sue her for defamation.
Actually, you would start with a cease and desist letter to anyone making these false accusations.
If this does not get a retraction, you will need to file suit for defamation. This cause of action is specifically for damage caused to one's reputation. To establish a prima facie case of defamation, four elements are generally required:
1. a false statement purporting to be fact concerning another person or entity;
2. publication or communication of that statement to a third person;
3. fault on the part of the person making the statement amounting to intent or at least negligence; and,
4. some harm caused to the person or entity who is the subject of the statement.
This involves complex litigation and it is strongly advised that you retain local counsel to assist you in protecting your rights before taking any action in this matter.
