Languages of the Court, Secretariat and of ICC Arbitrations
The Court’s official working languages are English and French.
In recent years, however, the Court has begun to hold special Court sessions for the scrutiny of arbitral awards in German and Spanish, when the awards themselves are in one of those languages.
The Secretariat's official working languages are also English and French, but Secretariat personnel speak approximately 30 languages. The Court's official written correspondence is also available for arbitrations in German, Spanish and Portuguese.
