N.Y. Comp. Codes R. & Regs. tit. 9 § 2520.13
An agreement by the tenant to waive the benefit of any provision of the RSL or this Code is void; provided, however, that based upon a negotiated settlement between the parties and with the approval of the DHCR, or a court of competent jurisdiction, or where a tenant is represented by counsel, a tenant may withdraw, with prejudice, any complaint pending before the DHCR. Such settlement shall be binding upon subsequent tenants. However, where the settlement encompasses surrender of occupancy by the tenant or the tenant is no longer in possession of the housing accommodation as of the date of the settlement, such settlement shall not be binding upon any subsequent tenant, except to the extent that the complaint being settled is subject to the time limitations set forth in the RSL and this Code.
