Fl. DMV won' transfer a clean open title to me.

I would exhaust all my own efforts within reason before I contacted a lawyer. A few internet searches and telephone calls would be worth my time. The OP did not detail specifically what he and the seller have done in the 2 months time but I would take the reins myself and try and get this done. I would also contact Florida DMV for their guidance. I am not here to speculate but to assist.
