Hernando, this sounds like a complicated situation, and an emotionally draining one. It is important here to take a step back, prioritize, and figure out what exactly you are looking for. If the landlord has filed charges against you (has he or she also filed a civil suit against you?), you need to consult with a criminal defense attorney ASAP and can find one on this site. Is the landlord's eviction suit against you still pending? If you are interested in fighting the eviction suit or counter-suing the landlord for wrongful eviction, I'd recommend consulting with a landlord/tenant attorney so he or she can advise you regarding the eviction suit, possible defenses, and potential claims against the landlord. You can also find a landlord/tenant attorney on this site. I wish you the best. Hope this helps.
Yes, he can. If he does, retain a criminal defense lawyer.
If you want to sue him for wrongful eviction, and if you have any damages from the eviction, hire a civil lawyer to consider the matter.
