Talking before pleading

Mediation is a voluntary process in which a neutral third party helps the parties find a solution themselves. In art, where relationships last — between gallery and artist, between collector and auction house — it preserves what a trial destroys.
The TAO has offered a mediation service since 2016. It has 36 mediators, trained in conducting negotiations and in the specifics of the art market. Nearly two mediations in three end in agreement, in seven weeks on average.
This section presents the principle, the mediators and the request for mediation.

Why choose mediation
Mediation is fast, discreet and inexpensive. It leaves the parties in control of the result: they can devise solutions a judge could not impose, such as an exchange of works, a sharing of the price, a joint exhibition or a corrective to a catalogue.
It is particularly suited to disputes where the parties wish to continue their relationship, to emotionally charged cases — inheritances, restitutions — and to those where legal uncertainty makes the outcome of a trial a gamble.
A confidential and voluntary process
Nothing said in mediation may afterwards be used before the arbitral tribunal or before a judge, unless agreed. Each party remains free to stop the process at any time. The mediator has no power of decision.
The agreement reached may be recorded in a consent award made by an arbitrator, which gives it enforceable force internationally.
Mediation and arbitration together
A mediation-arbitration clause provides first for mediation, then for arbitration if it fails. The TAO offers a variant in which the mediator may not afterwards sit as arbitrator, in order to preserve the parties' freedom of speech.
Mediation may also be decided during arbitration, with suspension of the proceedings if the parties so request. Time limits are then extended accordingly.
Solutions a judge cannot deliver
Mediation agreements reached at the TAO frequently contain creative clauses: joint exhibition of the work, long-term loan to a museum, sharing of any capital gain, publication of an erratum, founding of a prize. These solutions meet the parties' real interest more surely than a judgment.
They must, however, be drafted precisely. The mediator and the Registry help to formulate the undertakings and, if the parties wish, to record them in a consent award.
