Section 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.
