N.Y. Lien Law § 11-b: Copy of notice of lien to a contractor or subcontractor

§ 11-b. Copy of notice of lien to a contractor or subcontractor.

Within five days before or thirty days after filing a notice of lien in

accordance with section ten of this chapter or the filing of an

amendment of notice of lien in accordance with section twelve-a of this

chapter the lienor shall serve a copy of such notice or amendment by

certified mail on the contractor, subcontractor, assignee or legal

representative for whom he was employed or to whom he furnished

materials or if the lienor is a contractor or subcontractor to the

person, firm or corporation with whom the contract was made. A lienor

having a direct contractual relationship with a subcontractor or a

sub-subcontractor but not with a contractor shall also serve a copy of

such notice or amendment by certified mail to the contractor. Failure to

file proof of such a service with the county clerk within thirty-five

days after the notice of lien is filed shall terminate the notice as a

lien. Any lienor, or a person acting on behalf of a lienor, who fails to

serve a copy of the notice of lien as required by this section shall be

liable for reasonable attorney's fees, costs and expenses, as determined

by the court, incurred in obtaining such copy.
