We can not get paid for a commercial job (hotel) that we delivered all the goods to in Brooklyn, NY in February 2020. On May 18th, we sent a Notice of Intent to Lien; however, this has failed to deliver as the tracking states undelivered "Notice Left (No Authorized Recipient Available)." We are ready to file a mechanics lien on the property. Will it be an issue if the intent was not delivered first? Also what happens if we cannot deliver the lien to the property owner similar to the intent to lien?
