My question is related to the following. We did a preliminary notice on an address that we thought was the location. This was to the best of our knowledge at the time. The customer did not pay. We contacted the GC but they agreed to pay us but then changed there mind and stated that they never received a preliminary notice. Looks like the job was near the location we had our equipment at. Do we have any recourse? Can we still move forward with a mechanics lien?
