New York Mechanics Lien Statutes: Deadlines, Venues & Citations
Where New York liens are filed and enforced
A New York mechanics lien is filed with the County Clerk in the county where the project sits — 8 months (comm) / 4 mo (res) from last date of furnishing. Filing in the wrong county does not perfect the claim, which matters on projects that straddle county lines. Those are two different clocks against two different offices, and New York claimants lose rights far more often by missing the second one than the first.

Frequently Asked Questions

8 months (comm) / 4 mo (res) — From last date of furnishing. The filing goes to the County Clerk in the project's county. See N.Y. Lien Law § 10. The clock runs from the claimant's own last furnishing or completion, not the invoice date.
Where do you file a mechanics lien in New York?
With the County Clerk in the county where the property is located. Recording in the wrong county does not perfect the lien.
Does New York require a preliminary notice?
Not for most claimants (N/A). Sub-tier claimants should still document first furnishing, because New York's filing and enforcement windows are applied strictly.
How long do you have to enforce a New York mechanics lien?
1 year — From filing. A recorded lien left unenforced past that window generally expires and can expose the claimant to slander-of-title risk if it stays on record.

Yes. New York claimants can serve a stop notice within 8 months of last furnishing on the Construction Lender (NY Lien Law § 37). It reaches project funds rather than the real property, and can run in parallel with the lien.
