We are a fabricator of "specially fabricated items", which as I understand, means in NY state that we can file a lien on a property for services performed offsite in our shop. In this instance, building a custom sign for a commercial renovation project, in addition to other custom metalwork. During production the GC on the project sent an email stating that the work had been halted by the client, and the project may not move forward. We stopped fabricating at that time. However work effectively continued on this project for another several weeks while we moved and stored the metalwork pieces which were in progress; engaged in administrative work and went to meetings with the GC to negotiate the amount that would be paid on the uncompleted work. So is the "last date services are furnished" the date we received the email advising work was being halted? Or the day we finished wrapping the unfinished pieces and put them in storage? Or the day these items were eventually disposed of due to non-payment of an agreed on settlement amount? Finally, can we file a lien on specially fabricated pieces (metalwork) that was not yet in production on the shop floor at the time of the work being halted, but had received extensive drafting work, complete with shop drawings submitted to the designers for review. Thank you!
