New York Consolidated Laws, Lien Law - LIE § 201-a. Proceeding to determine validity of liens

Within ten days after service of the notice of sale, the owner or any person entitled to notice pursuant to section two hundred one of this article may commence a special proceeding to determine the validity of the lien. The special proceeding may be brought in any court which would have jurisdiction to render a judgment for a sum equal to the amount of the lien. If the owner or any such person shall show that the lienor is not entitled to claim a lien in the property, or that all or part of the amount claimed by the lienor has not been properly charged to the account of such owner or such person, or, as the case may be, that all or part of such amount exceeds the fair and reasonable value of the services performed by the lienor, the court shall direct the entry of judgment cancelling the lien or reducing the amount claimed thereunder accordingly. If the lienor shall establish the validity of the lien, in whole or in part, the judgment shall fix the amount thereof, and shall provide that the sale may proceed upon the expiration of five days after service of a copy of the judgment together with notice of entry thereof upon the owner or such person, unless the property is redeemed prior thereto pursuant to section two hundred three of this article. If the lien is cancelled, the judgment shall provide that, upon service of a copy of the judgment together with notice of entry thereof upon the lienor, the owner or such person shall be entitled to possession of the property.
