Arbitration in Ibero America: a comparative perspective - Second edition

The CMS Ibero American Arbitration Group (GIA) analyses key arbitration issues in Brazil, Chile, Colombia, Spain, Mexico, Peru and Portugal

28 Jul 2026 International 2 min read
Companies are increasingly turning to arbitration as an effective, confidential and flexible mechanism for resolving disputes, particularly those involving greater complexity or cross‑border elements. Coordinated advice and strong local knowledge are essential to defining a robust strategy, from the drafting of the arbitration clause through to the enforcement of the award.

At CMS, we have established the Ibero‑American Arbitration Group (GIA), a team made up of specialists from Brazil, Chile, Colombia, Spain, Mexico, Portugal and Peru, working closely with colleagues in other jurisdictions across the region. We support clients in domestic and international disputes and in court proceedings related to arbitration, including the recognition and enforcement of awards, following a practical, rigorous and results‑oriented approach.

Through this content series, we share practical insights for legal teams and business decision‑makers who need to anticipate risks, understand local legal frameworks and make informed decisions in relation to arbitration. The articles are written by arbitration specialists, acting both as arbitrators and as counsel, from the various CMS jurisdictions: Brazil,  Chile, Colombia, Spain, Mexico, Peru and Portugal. The authors combine an international outlook with strong domestic expertise, addressing the issues from this dual perspective.
