Wow that sucks. I'm not from fl but I think what I have learned in the past is pretty relevant nation wide. A lien can only be put on something if u are a business not personal and small claims you can run into the same problem why individuals can't place liens. Which is the proof the paper work. You would need a detailed work order specifying work to be done and price of work to be done with the individuals signature. Then if you were taking payments that would have to be iteamized and so on. But you could always try. Sorry to hear.
