N.Y. Lien Law § 12: Notice of lien on account of public improvements

§ 12. Notice of lien on account of public improvements. At any time

before the construction or demolition of a public improvement is

completed and accepted by the state or by the public corporation, and

within thirty days after such completion and acceptance, a person

performing work for or furnishing materials to a contractor, his

subcontractor, assignee or legal representative, may file a notice of

lien with the head of the department or bureau having charge of such

construction or demolition and with the comptroller of the state or with

the financial officer of the public corporation, or other officer or

person charged with the custody and disbursements of the state or

corporate funds applicable to the contract under which the claim is

made. The notice shall state the name and residence of the lienor, the

name of the contractor or subcontractor for whom the labor was performed

or materials furnished, the amount claimed to be due or to become due,

the date when due, a description of the public improvement upon which

the labor was performed and materials expended, the kind of labor

performed and materials furnished, and materials actually manufactured

for but not delivered to such public improvement, and give a general

description of the contract pursuant to which such public improvement

was constructed or demolished. If the lienor is a partnership or a

corporation, the notice shall state the business address of such

partnership or corporation, the names of the partners, and if a foreign

corporation, its principal place of business within the state. If the

name of the contractor or subcontractor is not known to the lienor, it

may be so stated in the notice, and a failure to state correctly the

name of the contractor or subcontractor shall not affect the validity of

the lien. The notice must be verified by the lienor or his agent, to the

effect that the statements therein contained are true to his own

knowledge, except as to the matters therein stated to be alleged on

information and belief, and that as to those matters he believes it to

be true. The comptroller of the state or the financial officer of the

public corporation or other officer or person charged with the custody

and disbursements of the state or corporate funds applicable to the

contract under which the claim is made shall enter the same in a book

provided for that purpose, to be called the "lien book". Such entry

shall include the name and residence of the lienor, the name of the

contractor or subcontractor, the amount of the lien and date of filing,

and a brief designation of the contract under which the lien arose.
