About Esteban
Esteban Leccese built his legal foundation in Argentina and deepened it in the United States. He earned a J.D. from the National University of Tucumán in 1996 and later completed an LL.M. at Columbia University in 2001. Those academic stops set the tone for a career split between teaching and practice.
He returned to Argentina to teach. At the National University of Tucumán Law School he served as an assistant professor of contract law, lecturing on the mechanics of agreement formation and interpretation. He also taught civil and commercial contracts as an assistant professor at Austral University Law School in Buenos Aires. Students and colleagues knew him as an instructor who combined doctrinal detail with practical scenarios drawn from commercial life.
Leccese has also worked in private practice. In 2017 he took an of counsel position at Ajamie LLP. That role brought him into a U.S.-based litigation and counseling environment after years in academic settings. The move reflected a pattern in his career: alternating between analysis in the classroom and direct involvement in client matters.
Outside of work and teaching he participates in professional groups. He holds membership in CARAT, the Argentine Committee for National and Transnational Arbitration, based in Buenos Aires. He is also a member of the American Bar Association. Those affiliations track with the subjects he teaches and the types of disputes he has handled.
Licensed to practice in both Texas and Argentina, Leccese navigates matters that touch cross-border issues. His academic focus on contracts and his membership in an arbitration committee suggest a concentration on commercial agreements and dispute resolution. He has experience explaining contract concepts to judges, students and clients, and translating Spanish-language legal frameworks into a U.S. practice context.
Colleagues describe his approach as methodical. He favors close reading of contract language and attention to applicable procedural rules. He has moved comfortably between Argentine legal education and U.S. practice settings, a path that shapes how he handles cases that involve parties or laws from both countries. He currently practices at Ajamie LLP, handling civil and commercial contract matters and issues in international arbitration.
