Enforcing Awards Against Sovereign States

An arbitral award against a sovereign state is, on its own, a piece of paper. Its value depends entirely on whether — and where — it can be enforced, a question too many claimants leave until after the tribunal has ruled.

This paper sets out the enforcement framework under the New York Convention and the ICSID Convention, and examines the practical strategy of asset identification: which state assets are, as a matter of both law and practicality, actually reachable by a claimant seeking to enforce.

Sovereign immunity remains the central obstacle. Most jurisdictions restrict enforcement to assets used for commercial rather than sovereign purposes — a distinction that sounds clean in the abstract and is frequently contested in practice, particularly for state-owned commercial entities operating at arm's length from the state itself.

The paper concludes with a practical framework: mapping likely enforcement jurisdictions and asset classes before an arbitration begins, not after an award is issued, materially changes both the settlement dynamics during the arbitration and the realistic recovery once it concludes.
