Practice Areas

Leks&Co offers comprehensive and strategic legal services in international arbitration, assisting clients in resolving cross-border disputes with efficiency and precision. Our practice is rooted in a deep understanding of international arbitral frameworks and a strong record of success across high-stakes matters. We are trusted by multinational corporations and domestic clients alike to navigate arbitration proceedings that demand not only legal acumen, but also cultural fluency and commercial sensitivity.

Our firm has extensive experience representing parties in proceedings governed by leading institutional rules, including the International Chamber of Commerce (ICC) and the Singapore International Arbitration Centre (SIAC). We focus particularly on complex disputes within the construction, real estate, and commercial sectors—areas where contractual intricacies and jurisdictional challenges require sophisticated legal strategy. From reviewing and drafting arbitration clauses to representing clients during hearings and managing the enforcement of arbitral awards, we provide end-to-end legal support tailored to our clients’ business goals. 

We assist clients in navigating jurisdictional issues, arbitrability questions, and conflict of laws, as well as advising on selection of arbitrators and venue. Our team is equipped to handle both investor-state and commercial arbitrations, and we regularly collaborate with foreign counsel to provide coordinated, multi-jurisdictional representation. At every stage, we focus on delivering efficient, enforceable, and business-minded outcomes.

Our commitment to international arbitration extends beyond representation. We are also recognized contributors to global thought leadership in this area. Leks&Co authored the Indonesian chapters of Global Arbitration Review – Construction Arbitration (2024) and Know-how Construction Arbitration (2025), providing insights into Indonesia’s legal framework and procedural nuances. In addition, we contributed to the International Comparative Legal Guide – International Arbitration 2024 (ICLG), further demonstrating our expertise and engagement with the evolving landscape of international dispute resolution.

As a testament to our capabilities, we proudly represent a Singapore contractor firm in an ongoing arbitration before the International Chamber of Commerce (ICC). This case involves a dispute within a consortium partnership and showcases our ability to handle technically and commercially complex matters in an international forum.

At Leks&Co, we combine legal excellence with strategic insight to deliver results that matter. Our international arbitration practice reflects our unwavering focus on protecting our clients’ interests in cross-border disputes while maintaining the highest standards of advocacy, professionalism, and efficiency.
