While international arbitration spans multiple types of claims, overlapping jurisdictions and legal regimes, there are some commonalities to consider it an appropriate subject for a brief addendum within this guidebook’s framework. A practitioner considering a transaction involving third-party funding of international arbitration will need to consider multiple potentially relevant jurisdictions. For example, one might need to consider the applicable arbitral rules (if any), the law of the seat of the arbitration, the governing law of the underlying agreements, any applicable international treaties, the law of the jurisdiction in which the award will be enforced, and, potentially, the law of the parties’ counsels’ home jurisdictions. Accordingly, this addendum is necessarily limited and endeavours to highlight some of the issues and approaches that are common in the context of third-party funding and international arbitration.
