Lanier Saperstein




Lanier is a partner in Dorsey’s New York office, co-chair of the firm’s global China Litigation Practice Group and a leading member of the firm’s Banking Industry Group.

With almost 20 years of experience, Lanier handles litigation and regulatory matters for foreign banks and other foreign financial institutions, especially those matters involving cross-border legal issues. Examples of Lanier’s successes include the following.  Lanier won a high-profile case representing three large Chinese banks in the US against an attempt to seize PRC government assets located in China.  He won a decision for a global bank on an issue of first impression concerning the intersection of international fund transfers and various federal and New York State statutes. He was the first attorney to successfully persuade a US court to require a litigant, due to concerns of international comity, to utilize the Hague Convention in requesting confidential bank records from China and to quash a US-issued subpoena. 

Lanier routinely writes on topics impacting foreign financial institutions, and his articles have appeared in the Wall Street Journal, New York Law Journal, the International Financial Law Review, and The Review of Securities & Commodities Regulation. He has been quoted in major US and Chinese media outlets, including Bloomberg Businessweek, People’s Daily, Tencent, and Sing Tao Daily.  He is on the panel for the Shanghai International Arbitration Center (SHIAC) and is an adjunct professor at Fordham University School of Law, where he teaches a class on international banking litigation.
