New York Consolidated Laws, Real Property Actions and Proceedings Law - RPA § 763. Redemption by creditor of lessee

In a case specified in section 761, a judgment creditor of the lessee whose judgment was docketed in the county before the precept was issued, or a mortgagee of the lease whose mortgage was duly recorded in the county before the precept was issued, unless by the terms of the lease the lessee shall have waived his right to redeem, or such lessee, or his executor, administrator or assignee shall have subsequently waived the right to redeem by a written instrument filed and recorded in the office in which the lease is recorded, or if not so recorded, in the office in which deeds are required to be recorded of the county in which the leased premises are located, before such judgment was docketed or such mortgage recorded, or such judgment creditor or mortgagee himself shall have waived in writing his right to redeem, may at any time before the expiration of one year after the execution of the warrant, unless of redemption has been made as prescribed in section 761, file with the court which issued the warrant a notice specifying his interest and the sum due to him, describing the premises, and stating that it is his intention to redeem as prescribed in this section.  If a redemption is not made by the lessee, his executor, administrator or assignee within a year after the execution of the warrant, the person so filing a notice, or, if two or more persons have filed such notices the one who holds the first lien, at any time before two o'clock of the day, not a Sunday or a public holiday, next succeeding the last day of the year, may redeem for his own benefit in like manner as the lessee, his executor, administrator or assignee might have so redeemed.  Where two or more judgment creditors or mortgagees have filed such notices, the holder of the second lien may so redeem at any time before two o'clock of the day, not a Sunday or a public holiday, next succeeding that in which the holder of the first lien might have redeemed;  and the holder of the third and each subsequent lien may redeem in like manner at any time before two o'clock of the day, not a Sunday or a public holiday, next succeeding that in which his predecessor might have redeemed.  But a second or subsequent redemption is not valid unless the person redeeming pays or tenders to each of his predecessors who has redeemed the sum paid by him to redeem and also the sum due upon his judgment or mortgage;  or deposits those sums with the court for the benefit of his predecessor or predecessors.
