Stephen Cha-Kim represents global clients in cross-border disputes and in federal and state court litigation across the U.S. From his eight years as an Assistant U.S. Attorney for the Southern District of New York, Stephen brings extensive experience handling all stages of civil litigation, having managed multi-agency investigations of corporate, public, and non-profit entities, obtained numerous trial victories and favorable settlements, and briefed and argued appeals raising issues of first impression.

At SDNY, Stephen led affirmative and defensive matters involving financial and healthcare fraud, as well as environmental, employment, administrative, national security, international, civil rights, and art law. He oversaw major enforcement matters under the Clear Air Act and other environmental statutes; bet-the-company False Claims Act investigations and litigation, including helping win, at US$300 million, one of the largest mortgage fraud judgments ever awarded following a jury trial; internal investigations of federal agencies for alleged discriminatory employment practices and related litigation; and significant commercial and intellectual property disputes involving the Departments of State and Defense, the Export-Import Bank, and the Smithsonian Institution. During his government tenure, Stephen was also detailed to the White House as Associate Counsel to the President, advising the Biden Administration on matters related to environmental regulation and litigation.

Stephen has served as an Adjunct Professor at New York University School of Law, co-teaching a course on government civil litigation, and at Fordham Law School (2018-2020), where he taught legal writing. He has also been a faculty member of the Practicing Law Institute.

Stephen began his legal career as a Skadden Fellow litigating employment matters in federal and state courts at Make the Road New York, a leading non-profit organization.
