Chaffetz Lindsey Promotes Matilde Flores and May Khoury to Counsel
New York, New York – Chaffetz Lindsey is pleased to announce that Matilde Flores and May Khoury have been promoted to Counsel effective January 1, 2025.
Matilde Flores’ practice focuses on investment arbitration, international commercial arbitration, and public international law disputes. She has recently played a significant role in several high-stakes construction, energy and life sciences cases involving disputes in the US, Mexico, and Argentina. Matilde is an active member of the international arbitration community—she was appointed Co-Chair of the Latin America Interest Group at the America Society of International Law in 2024 and is involved in the ICC Young Arbitrators Forum and the LCIA Young International Arbitration Group. Legal 500 Latin America has recognized Matilde as a Leading Associate in 2025.
“I have had the pleasure of working closely with Matilde Flores on several high stakes hearings in English and Spanish,” said Chaffetz Lindsey partner Anibal Sabater. “She is exceptionally dedicated and talented, and a pleasure to work with. We are delighted to announce her promotion to Counsel and look forward to her continued contribution to our clients’ success in her new role. Given her legal acumen and commitment to excellence, I am sure she will thrive in her new position.”
Prior to joining Chaffetz Lindsey, Matilde was based in Paris as an associate in the arbitration practice of an international law firm. She graduated with a B.A. (with First Class Honors) and J.D. from McGill University in Montreal. Matilde has practiced law in Mexico City, Paris, and New York and is fluent in English, Spanish, and French.
May Khoury has extensive experience in commercial and investment disputes involving across the Americas, the Middle East, and Africa. Most recently, she has worked on complex cases involving an infrastructure project in Panama, a power plant in Mexico, and ISDS cases involving Argentina, the Czech Republic, Mexico and the UAE. She is trilingual in English, Arabic, and French and has participated in proceedings in all three languages.
Together with Chaffetz Lindsey partners Yasmine Lahlou and Caline Mouawad, May has been particularly involved in the firm’s MENA (Middle East and North Africa) practice. She is a member of the New York City Bar Middle Eastern & North African Affairs Committee, and is among five international arbitration practitioners who launched ArabArb, a networking group for international arbitration practitioners with roots, affinity, or interest in the Arab World. The organization was nominated for the GAR: Equal Representation Arbitration Pledge Award in 2024.
“May is a very talented lawyer whose broad international experience and impressive language skills have made a significant contribution to our arbitration practice. While her encyclopedic knowledge of ISDS arbitration has been an asset since joining us six years ago, more recently May has shown she is equally adept in commercial disputes,” commented Chaffetz Lindsey founding partner and head of the firm’s international arbitration practice James Hosking.
Prior to joining Chaffetz Lindsey, May worked at leading international law firms in Paris, Dubai, and New York. She graduated with honors from Harvard University (B.A.), Institut d’Etudes Politiques de Paris (M.A.), and Boston College Law School (J.D.).
