I contracted with a contractor for a construction job. Who I assumed to be his employee, "Brad", signed off on the construction contract as an officer on behalf of the contractor. Over a year later, Brad sends me a preliminary notice to lien. Apparently, he had some kind of agreement with the contractor before to work on my project that I was never aware of. Brad is not licensed and was only a consultant. Can he put a mechanics lien on my property? Can't I just tell him that he has to go to the contractor to get paid? The job is not yet finished.
