Practice Experience

Blair C. Fensterstock founded Fensterstock & Partners LLP, a commercial litigation boutique in New York, where he is the Managing Partner.  Prior to founding his present firm in 1998, Mr. Fensterstock was with Simpson Thacher & Bartlett, Dewey Ballantine, and Sutherland Asbill & Brennan. From 1984-1992, he served as head of litigation for Saul Steinberg’s Reliance Group and then General Counsel of Frank B. Hall & Co., Inc.

Mr. Fensterstock has served as President of the New York American Inn of Court, on the Board of the Center for Security Policy, on the Board of Visitors of Columbia Law School, and presently is a member of the Board of the New York County Lawyers Association and the Financial Policy Council Board. In addition, he currently serves on the Board of a number of corporate clients.

Mr. Fensterstock specializes in complex commercial litigation in all areas including securities, tax shelters, fraud, insurance and reinsurance, partnership disputes, intellectual property,  employment, accounting malpractice, construction, and defamation.

Having litigated in both the  corporate and private law firm environments, he has successfully merged his extensive economic background and his over-35-years of litigation expertise to create novel and cost- effective means to litigate “out of the box” in a David v. Goliath world. His accomplishments include successfully trying the largest tax shelter cases in the U.S., all of the civil cases arising from the bombing of the World Trade Center in 1993,  a plethora of securities, intellectual property and trade secret litigations across the U.S., as well as cases in the Hague and Brazil.

Mr. Fensterstock is often quoted in Bloomberg News, The Wall Street Journal, The New York Times, and on CNN, NBC, CBS, and in the Asian press. He has been honored as a New York Super Lawyer, is listed in a number of Who’s Who publications including as Professional of the Year for Commercial and Civil Litigation, and is the author of the chapter on Complaints in the leading West publication, Commercial Litigation in New York State Courts.
