In an Ad Hoc Arbitration the arbitrators can be chosen by mutual agreement. But when parties already have a dispute this agreement is not so easy. Therefore they often ask a third party to appoint the arbitrators (= institutional arbitration).

The Institute of Arbitration is often asked :

• to appoint an arbitrator in an Ad Hoc arbitration
• to manage the complete procedure by the Standard Rules Dispute
• to provide logistic support to disciplinary chambers or arbitration committees and their arbitrators
