Conciliation professionals

The success of a mediation depends largely on the personality of the mediator. The TAO keeps a list of 36 mediators of 22 nationalities, chosen for their training, their experience of conflict and their knowledge of the art world.
The mediators are former judges, lawyers, curators, market experts or occupational psychologists. All have undergone specific training and signed the tribunal's code of ethics.
This page presents their profile, the selection procedure and their obligations.

Training and ethics
Each mediator shows a certified training in mediation (at least forty hours), five years of experience and knowledge of the art market. Each follows one day of continuing training per year and takes part in practice-analysis groups.
The code of ethics requires impartiality, confidentiality, competence and loyalty. The mediator declares any link with the parties or their counsel before accepting the assignment, and withdraws in the event of a conflict of interest.



Choosing a mediator
The parties may agree together on the name of a mediator. Failing that, the Registry proposes a list of three names matching the language, type of dispute and availability required, among which each party ranks its preferences. The Registry then appoints the mediator with the best joint ranking.
A mediator outside the list may be appointed with the Registry's agreement, provided that the mediator complies with the code of ethics. A pair of two mediators may be proposed for complex or multicultural disputes.
Fees and organisation
Fees are set by the tribunal's scale: a basic flat fee for preparation and two sessions, then an hourly rate. They are shared equally between the parties unless otherwise agreed. For a €100,000 dispute, the average cost is €3,200, including administrative costs.
Sessions may be held on the TAO's premises, at one of the parties' premises or remotely. The mediator has a secure space on the Desk to exchange documents with the parties.
Becoming a mediator
Candidates must hold a certified training, have at least five years of relevant professional experience and a good command of two languages. The file is examined by a committee that arranges an interview and role-play exercises.
Appointment is valid for three years, renewable after evaluation by the parties and the Registry. A mentoring programme pairs new mediators with experienced colleagues during their first assignments.
