N.Y. Real Property Law § 226 (2026)

§ 226. Effect of renewal on sub-lease. The surrender of an under-lease
is not requisite to the validity of the surrender of the original lease,
where a new lease is given by the chief landlord. Such a surrender and
renewal do not impair any right or interest of the chief landlord, his
lessee or the holder of an under-lease, under the original lease;
including the chief landlord's remedy by entry, for the rent or duties
secured by the new lease, not exceeding the rent and duties reserved in
the original lease surrendered.
