Hi! I am a GC and I agreed to a deal with a city urban renewal agency i New Jersey to provide labor/materials to a blighted property that had been foreclosed upon under the condition that the ownership transfers to me when I am done. Now that I have furnished work and labor as agreed upon, they wont give me the property so I need to start the process of filing a lien/claim Is this a public job, a commercial job, or a residential job? How do I proceed here?
