We signed the agreement with the homeowner to do the job on 09/08/2018. The work did not start until 05/23/2019 and we finished 6/3/19. We send a Notice of Intent to File A Lien, and now we want to File a Lien, as still did not received the payment. We did not sent the Notice of Lien Rights, as we were not aware we have to. We are General contractor, and we already paid all subcontractors and the supplier for material used for this job. This is a residential, one family building. Can we still file for a Lien? Is the Lien enforceable?
