Summary: The nature and extent to which "discovery" (a common law term referring to pretrial disclosure of documents and other information) is available in international arbitration continues to vary widely from case to case, depending on the terms of the parties' agreement, including the rules and arbitration situs chosen by the parties. The nationality of the arbitrators and of the parties' counsel also may play a decisive role in determining the amount of discovery parties may obtain in an international case. This article surveys discovery law and practice in international arbitration and discusses circumstances where parties may wish to provide for discovery in their international arbitration clauses.
