Ad hoc arbitration

Arbitration that is not administered by an arbitral institution (cf Institutional Arbitration). The parties do not benefit from any assistance in case of difficulty other than from the courts of the seat of arbitration, who may provide support if they have jurisdiction. Parties to an ad hoc arbitration may agree to the use of established arbitration rules, such as UNCITRAL Arbitration Rules, and may provide for an appointing authority to assist them in the constitution of the arbitral tribunal or the appointment of a sole arbitrator.
