A directory to help decide

The directory brings together the entries of the TAO's 142 arbitrators. It can be consulted online without an account and allows filtering by language, country, chamber, specialism and availability. It is used to prepare the appointment of arbitrators, but also to understand who sits on the tribunal.
Entries are updated every quarter, from information supplied by the arbitrators and checked by the Registry.
This page describes the filters, the content of an entry and the data protection rules.

Searching the directory
Search is by name, but also by cumulative filters: languages of proceedings, chamber, specialisms, country of practice, law taught, availability. A free-text search engine finds arbitrators by keywords: "Chinese ceramics", "tribal art", "restitution", "Islamic law".
Results are sorted by relevance. A button adds an arbitrator to a list of candidates that can be shared with your counsel or with the opposing party.



The content of an entry
The entry shows a photograph, languages, country, career, specialisms, date of listing, number of cases and a brief curriculum. It also states availability (immediate, within two months, limited) and any declared links with the market.
Personal contact details are not published. All contact goes through the Registry, which informs the arbitrator and ensures equality between the parties.
Personal data and accuracy
Arbitrators consent to the publication of their entry. They can correct it at any time. The tribunal publishes neither individual fees nor evaluations. The information is kept for the duration of the listing and then archived for five years.
If any information seems inaccurate to you, report it to the Registry. The parties may also report an undeclared link, which may justify a challenge.
Selection assistance
The Registry offers a pre-selection service: from a short description of the dispute (language, type, stakes, time frame), it suggests three names, with their availability. The parties remain free to choose elsewhere.
This service is free of charge and does not prejudge the appointment, which is for the parties or, failing that, the council. The suggestions are sent to both parties simultaneously to preserve fairness.
