Dyalá Jiménez

Dyalá Jiménez is a Costa Rican international arbitrator and the founder of DJ Arbitraje, an international arbitration practice based in San José, Costa Rica. The firm has been named Arbitration Law Firm of the Year in Costa Rica at the Corporate INTL Global Awards 2025, recognising the strength of a practice built around one of the region's most highly regarded arbitrators. Jiménez focuses on both commercial and investment arbitration, frequently sitting as presiding arbitrator in significant international disputes.

Her experience in the field is extensive. She has acted as arbitrator in more than forty cases spanning energy, infrastructure, commerce and investor-state disputes, a body of work that reflects both the breadth of her expertise and the confidence placed in her by parties and institutions. She is ranked in the top band by Chambers and Partners for international arbitrators and has been designated a global elite thought leader by Who's Who Legal, distinctions that underline her standing among the leading practitioners in international dispute resolution.

Arbitration is the discipline at the heart of the award, and Jiménez's involvement in the field extends well beyond acting in individual cases. She is a member of the International Court of Arbitration of the ICC, sits on the board of governors of the International Council for Commercial Arbitration, and serves on Costa Rica's panel of arbitrators for ICSID, the World Bank's investment dispute body. Through these roles she contributes to the governance and development of international arbitration as a system, not merely as a participant within it.

Her career reflects a rare combination of practice, public service and scholarship. She served as Costa Rica's Minister of Foreign Trade between 2018 and 2020 and earlier advised the Minister of Finance, experience that gives her a deep understanding of the state and trade perspectives that so often feature in investment disputes. She has also taught at institutions in Costa Rica and Chile and works across Spanish, English, French and Portuguese, allowing her to operate comfortably in the multilingual environment of international arbitration.

Through DJ Arbitraje, Dyalá Jiménez offers parties access to an arbitrator of exceptional experience and international standing, grounded in Costa Rica but engaged with disputes and institutions across the world. The firm's recognition as Arbitration Law Firm of the Year in Costa Rica at the Corporate INTL Global Awards 2025 affirms her reputation as a leading figure in the field, and the value of a practice dedicated to the fair and expert resolution of complex commercial and investment disputes.
