Biography

A partner in the Firm's Global Litigation Practice, Jeffrey Steinfeld is a first-chair trial and appellate lawyer and nationally recognized securities litigator who represents companies, financial institutions, and senior executives in high-stakes securities, corporate governance, and white collar matters.

Jeff's practice focuses on federal securities class actions, shareholder derivative and fiduciary duty litigation, SEC and government enforcement defense, and complex internal investigations. He regularly serves as lead counsel to boards, audit committees, and senior executives navigating parallel civil litigation, regulatory scrutiny, and reputational risk arising from public company disclosures, business combinations, digital asset transactions, and financial reporting.

Jeff has served as first chair in jury and bench trials in state and federal courts nationwide, including federal criminal proceedings involving insider trading and parallel SEC enforcement actions. He has led multiple appeals before the Delaware Supreme Court, the California Supreme Court, and the U.S. Courts of Appeals. His matters frequently involve multi-billion-dollar exposure, cutting-edge issues under the federal securities laws, and coordinated strategy across jurisdictions, including international arbitration proceedings.

He regularly litigates matters governed by Delaware law, including fiduciary duty, Caremark, and stockholder disputes in the Delaware Court of Chancery and on appeal.

Jeff is ranked by Chambers USA in both Securities Litigation and White-Collar Crime & Government Investigations—one of only two lawyers in California recognized in both categories. Chambers notes that "Jeff's responsiveness, depth of knowledge of securities law and complex matters, thoroughness and understanding of the issues around the assignment are beyond compare." He has appeared three times in The American Lawyer's Litigator of the Week and is recognized by The Legal 500, Lawdragon, Benchmark Litigation, and Best Lawyers.

He represents clients across technology and social media, cryptocurrency and digital assets, fintech, private equity and investment funds, commercial and investment banking, broker-dealers, and SPACs.

A recognized authority on securities and fiduciary duty law, Jeff writes and speaks frequently on developments in federal securities litigation, Delaware corporate law, and enforcement trends. His commentary has appeared in Law360, Bloomberg, Westlaw Today, and Reuters, and he has been featured in The National Law Journal, Delaware Business Court Insider, Private Equity Law Report, Agenda, and International Financing Review.

Jeff is an active member of the Central District of California's Pro Bono Panel and has served as a moot court judge for Berkeley Law's McBaine Honors Moot Court Competition.

He received his J.D., Order of the Coif, from the University of California, Berkeley School of Law, where he won the McBaine Honors Moot Court Competition. He earned his B.B.A. in finance, investments, and banking from the University of Wisconsin.

Prior to joining White & Case, Jeff was a partner at a leading international law firm.
