One Lex Partners is a New York-based boutique law firm advising importers, exporters, financial institutions, and investors on U.S. trade regulation. Our lawyers have served at U.S. government agencies, in senior in-house positions, and at leading international firms.

The Firm

We focus on a defined area of practice: U.S. customs and import compliance, export controls under the EAR and ITAR, economic sanctions administered by OFAC, and foreign investment regimes (OISP and CFIUS). We work with companies of all sizes, from venture-backed startups to multinational corporations, on matters that range from day-to-day compliance counseling to enforcement defense and high-stakes transactional work.

Our model is built on direct, senior-attorney engagement. Clients work with the partner handling their matter rather than through layers of associates. This produces faster decisions, clearer advice, and better economics than conventional firm staffing.
