Database of Arbitrators and Mediators

The MIAC Database features a global pool of both highly experienced and new arbitrators as well as mediators, drawn from civil and common law jurisdictions around the world.

In creating an online Database, MIAC aims to create a useful resource to users, and at the same time bring to the fore the recognized talent of arbitrators and mediators from Africa, Asia, and beyond.

The Database is freely accessible to the public for assistance in identifying appropriate arbitrators for specific cases. Appointments by the MIAC appointing authority may also draw upon, but would not be limited to, the Database. While MIAC encourages qualified individuals to join the Database, inclusion in the Database does not entail an endorsement or certification by MIAC.
