Attorney Information

Overview

Deborah E. Riegel joined Rosenberg & Estis, P.C. in 1994 and is a Member with the firm’s Litigation Department. During her tenure at the firm, Riegel has handled complex litigation before New York state and federal trial and appellate courts. Most notably, Riegel was lead counsel and successfully argued before the Court of Appeals in Matter of Regina Metro. Co., LLC v. New York State Div. of Hous. & Community Renewal, a case which is considered to be one of the most impactful decisions for the real estate industry in decades. The Court of Appeals adopted R&E’s arguments and found the enactment of portions of the HSTPA of 2019 to be unconstitutional in their retroactive application, saving property owners millions of dollars in potential rent overcharges and avoiding catastrophic underwriting and financing consequences. That victory was most recently reinforced in another case for which Riegel was lead counsel and argued before the Appellate Division, First Department: Burrows v 75-25 153rd Street, LLC. The Appellate Division again wholly adopted R&E’s arguments and definitively applied the Court of Appeals’ holding in Regina.

Over the course of her career, Riegel has successfully litigated cases of critical, industry-wide importance on a wide variety of complicated issues on behalf of some of the City’s most prominent owners and developers, including Vornado Realty Trust, The Durst Organization, General Growth Properties/Brookfield Properties and A&E Real Estate. Her practice more generally involves litigating matters related to commercial lease disputes, tort and contract actions, construction disputes, cooperative shareholder disputes, rent regulatory issues and residential and commercial landlord/tenant matters. She also provides counsel to cooperatives and condominiums on a wide range of matters. Riegel’s client base ranges from small owners of residential property to major residential and commercial developers, and her practice has given her a broad spectrum of experience representing clients in every Court from the Civil Court of the City of New York to the New York State Court of Appeals, as well as the United States District Court, United States Bankruptcy Court, and the United States Court of Appeals. While her practice is primarily focused on litigation, Riegel works with clients on development issues and has successfully vacated a number of development sites in Manhattan. Riegel also works with clients, with the support of the firm’s highly experienced Transactional Group, on purchase and sale agreements, leasing and construction management so as to provide a one-stop, integrated approach to managing clients’ legal needs with an eye toward risk management and early dispute resolution.

Riegel received her bachelor’s degree from Queens College of the City University of New York and her J.D. from Brooklyn Law School. She is a member of the Bar of the State of New York and is admitted to practice before the United States District Courts for the Southern and Eastern Districts of New York and the United States Supreme Court. Riegel was previously a member of the Committee on Cooperative and Condominium Law and the Housing Court Committee of the New York City Bar and currently serves on its Judiciary Committee.

Riegel’s approach to working with clients and resolving disputes was shaped by her work in private industry prior to attending law school, as well as her position as a legislative aide in the New York State Assembly. These experiences taught her the need to recognize the real-world value of a case to a client, and that negotiation and compromise are often the most valuable skills in litigation.
