International Arbitration — Our Services
Investment Arbitration
We are regularly instructed by both investors and sovereign states to act as counsel in international investment arbitrations arising out of bilateral and multilateral investment treaties.

The team acts at every stage of the investment arbitration process, from amicable settlement negotiations to enforcement and asset recovery under both ICSID and non-ICSID arbitral awards. We are experienced acting as counsel in investment treaty arbitrations proceedings under all the major arbitration rules – including ICSID and UNCITRAL Rules – as well as in arbitrations administered by the Permanent Court of Arbitration.

Our advisory expertise spans from advising governments on investment treaty and legislative drafting to advising clients on protections afforded by international investment treaties as part of their corporate structuring and planning.

Investment arbitrations may involve serious allegations of corruption and bribery. Backed up by our expertise in business crime, we are well placed to handle the most complex of cases.
