N.Y. Lien Law § 34: Waiver of lien

§ 34. Waiver of lien. Notwithstanding the provisions of any other law,

any contract, agreement or understanding whereby the right to file or

enforce any lien created under article two is waived, shall be void as

against public policy and wholly unenforceable. This section shall not

preclude a requirement for a written waiver of the right to file a

mechanic's lien executed and delivered by a contractor, subcontractor,

material supplier or laborer simultaneously with or after payment for

the labor performed or the materials furnished has been made to such

contractor, subcontractor, material man or laborer nor shall this

section be applicable to a written agreement to subordinate, release or

satisfy all or part of such a lien made after a notice of lien has been

filed.
