Caroline Zalka
Biography
Forbes named Caroline one of America’s Top Women Lawyers in 2026, and Euromoney honored her as North America Securities Lawyer of the Year at its Women in Business Law Americas Awards that same year. She was selected to three 2025 Lawdragon 500 lists — “Leading Lawyers in America,” “Leading Litigators in America,” and “Leading Global Litigators.” Chambers USA ranks Caroline as a leading securities litigator in New York, with clients describing her as “a brilliant lawyer — not only a great strategist and a great writer, but a very, very commanding personality in an adversarial setting,” someone whose “depth of understanding, both of the relevant facts and of applicable law, is consistently impressive,” who “stands out for how she understands the business objectives and how to get there in the least painful way,” and is “very sharp at seeing around corners.” Benchmark Litigation has named her a “Local Litigation Star” in New York for Securities Litigation, while Legal 500 recognizes her nationally as a top-ranked “Leading Partner” for Securities Litigation: Defense, and recommends her for M&A Litigation: Defense, based on her “incredible practical advice.”
Beyond the courtroom, Caroline advises boards of directors, board committees, and senior management on securities law, corporate governance, disclosure, and regulatory matters. She has deep experience with internal investigations and governmental and regulatory proceedings, including those brought by the DOJ, SEC, New York Attorney General’s Office, and New York District Attorney’s Office.
