My builder left a new box blade for an earth mover in my backyard following construction and closing in September of 2007. The builder lives in my community and I approached him several times to remove it and he assured me each time that he would. In Decemeber of 2007 I received a call from an equipment company claiming to want to reposses the box blade for non-payment. By that time I had errected a fence and installed a spinkler system and I advised the caller that I wanted proof of their rightful ownership and that I would hold them responsible for damages to my fence, grass and spinkler system. The caller refused to leave a name or contact information. It has been 6 months since my last contact with either party. I called the local district attorneys office to inquire about potential remedys and was advised that they could not offer me legal advise. Can I legally sell this thing and get it out of my yard? If not what remedy can I apply to this situation legally?
