The United Nations Commission on International Trade Law has provided options to states to permit and recognize oral agreements to arbitrate in international arbitration law. An historical and legal analysis of the formation, interpretation and application of international arbitration instruments reveals an emergence of customary international law recognizing oral agreements to arbitrate. This analysis assists in evaluating international legislative options to recognize and enforce oral agreements to arbitrate when they can be evidenced in writing.
"The written form requirement is for many a formality that is no longer justified.”
