Owner finance property - owner dies and title was never transferred

[Linda Garcia]

I purchased property and a mobile home from my step-father with owner financing. The following month he passed away. The mobile home was originally purchased by my father and brother for my step father and mother after their home burned down. My father wanted to stay out of the picture so my brother arranged to have the home delivered with the title in his name. It's been approximately 10 years since and the title was never transferred so my brother claims that he owns the home and is trying to benefit from my fathers good will. Does anyone know how to legally get this remedied? I expect I have to file something in court but I'm not sure where to begin. Any help is greatly appreciated.
