My question involves landlord-tenant law in the State of: FL
The shortest version possible -- The woman I worked for and was led to believe I was a 50% partner in a company with filed to evict me from the business property I was working and living on. While both of our names were supposed to be on the lease when signed, I was informed by her attorney that I was actually never put on the lease at all, and therefore I was as good as an "unwanted guest" that needed to get out. Her attorney told me that she had already filed suit against me, and that the only way she would "call off the dogs" was if I agreed to be out within 2 days (on Christmas Eve no less), as well as signed a stipulation which signed over a very valuable grand piano that belonged to my mother in exchange for some alleged "damages to the property" (which I later found out from the actual property owner that there were NONE.) It has been just over a year since this occurred, and with my mother's health beginning to fade in a grave capacity, I am finding that this piano keeps coming to mind, as it was one of the last possessions she had after going through a terrible divorce. Likewise, it would have also been the only belonging of hers that I would have had once she passes on, and it is of extra significance, as music was always a common love we shared.
My main question/s are as follows -- Is there a way I can legally challenge the stipulation? Secondly, is there a statute of limitations on a stipulation? Third, does this fall under the category of "signing under duress"? I have never been faced with anything legal in my life, so when faced with being homeless within 48 hours, on Christmas Eve, with an ill parent, AND facing legal threats from a powerful doctor and lawyer, all I could do was run to the first "jack in the box" attorney's office I could find. He basically reviewed the Doctor's stipulation and told me the only way to protect myself from the lawsuit was to sign it. I argued with both him and his paralegal, as there were two clauses I took SEVERE issue with. One being that it had me admitting fault to the alleged damages, and the second stating that I was signing and swearing to the fact that I was not being forced to sign under any duress, threat, or coercion, which was actually exactly what was happening. Obviously it also stated that I was signing over ownership of the piano in exchange for the "damages". He again told me that if I did not sign it, I would be "taken to the bank" with the full blown lawsuit. Having nothing as it was and about to be on the street, I saw no other choice and signed it. They closed the case.
About 2-3 months later I happened to run into the property owner himself, who was a bit confused as to why I had just disappeared from the equation and apologized that there was nothing he could since the doctor only named herself on the lease. Apparently she never even brought up the fact that I was (supposed to be) a 50% partner. Therefore since the property was solely hers, she was technically the landlord and had the ability to do whatever she wanted with me. I told him that she had accused me of causing in excess of $5000 worth of damage and asked him if there was anything wrong with the property after I'd left, to which he said absolutely not. Naturally I took photos of the entire property just minutes before leaving for good, and went so far as to call the police to come do a walkthrough to verify the condition, as my mother had a worry that she would come in behind us and cause damage herself. But the owner said everything was perfect. Obviously in my mind, that would mean she lied in the stipulation, but at that time I didn't have any means of fighting it. Can I do anything about this?
I also just want to state that this eviction came totally out of left field. There was nothing malicious on my part to cause it, I did not break any agreement with the doctor, and I truly believed I was a 50% partner until the day she showed up and told me to give her the keys, get in my car, and leave right at that very moment. She would not tell me what was going on, just kept telling me that I needed to get out, and within an hour her attorney was calling me. In hindsight, what seems to have occurred was that I was kept and used just long enough to get the business going and then told, "Surprise! You're not even on the lease! Thanks for doing the dirty work, now get out." Please help me. If there is any way I can get this much loved piano back for my mother, I would appreciate any advice on how to go about it, as I will most definitely be the ant up against the queen bee.
