Cross-Border Arbitration Representation
Cross-border disputes frequently arise from international investments, multinational commercial relationships, and state regulatory actions affecting foreign businesses.
Our lawyers represent clients in complex international proceedings involving:
- Investor-state arbitration
- Cross-border commercial arbitration
- Treaty disputes involving bilateral or multilateral agreements
- State responsibility and reparations claims
- Sovereign immunity and jurisdictional challenges
We manage disputes from early strategic assessment through to arbitration proceedings, final awards, and enforcement actions across jurisdictions.
Where appropriate, we work alongside domestic counsel, diplomatic advisors, and policy specialists to ensure that legal strategies align with broader commercial or governmental objectives.
Investor-State Arbitration
Foreign investors increasingly rely on international investment treaties and arbitration mechanisms to protect their rights when disputes arise with host states.
Our team advises and represents clients in investor-state arbitration proceedings involving claims related to:
- Expropriation or nationalization of investments
- Unfair or discriminatory regulatory measures
- Violations of fair and equitable treatment standards
- Breaches of investment protections under bilateral investment treaties (BITs) or trade agreements
- Jurisdictional and admissibility challenges in arbitration
We guide investors and institutions through the complexities of treaty interpretation, jurisdictional strategy, and international arbitration procedures.

Our cross-border litigation lawyers assist clients with:
- Strategic dispute planning and risk mitigation
- Multi-jurisdictional litigation coordination
- Evidence gathering across borders
- Negotiation and settlement of international disputes
- Enforcement or challenge of international arbitral awards
Our approach combines strong advocacy with pragmatic dispute management, ensuring clients receive clear strategic guidance in complex international environments.
