The Business Litigation Group handles complex commercial disputes where the stakes are highest — partnership and shareholder conflicts, corporate governance battles, fraud and business tort claims, contract disputes, and matters involving breach of fiduciary duty. Our clients include Fortune 500 companies, corporate banks, significant investors, private equity-backed companies, family-owned businesses, and top-tier law firms retaining us as national litigation counsel.
Our Approach
We are tenacious trial lawyers and that informs every decision we make from the moment a matter comes through the door.
Our approach to complex commercial litigation combines deep legal knowledge, courtroom experience, and business acumen. We understand what is on the line — not just legally, but operationally and reputationally — because our attorneys have sat on both sides of the table. We develop litigation strategy around our client's actual exposure and objectives, build the factual record from day one, and prepare every case as if it will be tried. Our clients receive senior-level engagement at every stage.
Jonathan B. Nelson, Co-Chair of the Litigation Department, has been recognized as a New York Metro Super Lawyers® honoree every year from 2013 through 2026 and is listed in Best Lawyers in America® from 2021 through 2026. His background spans felony criminal prosecution and in-house corporate counsel — a combination that produces a litigator who understands both how to win in court and how clients think about risk, cost, and outcome. Mark Zauderer is a prominent trial and appellate attorney whose clients have included major corporations, prominent individuals, and a Presidential cabinet secretary in significant business and financial litigation. The attorneys they lead are among the most experienced commercial litigators in New York and nationally.
We represent clients in federal and state courts across the country, from the United States District Courts and Courts of Appeals to state trial and appellate courts at every level. Our reach is national. Our attention is personal.
