New York Lien Forms
A party providing services or materials to a construction project in NY may file a mechanics lien against the property if they are unpaid. The lien must be filed within 8 months from last furnishing labor and/or materials. If the work is on a single-family residential project, the time to file is just 4 months from the same date.
A copy of the lien must also be served on the property owner and anyone above the claimant in the contracting chain within 30 days of filing, and proof of delivery must be filed.
