The French law, the most rigorous concerning the reliability of the Fine Art experts, allows everybody to express his rights in the case of a debate.

The expert is reliable for his expertises.

This is the reason why the C.N.E.S. since its foundation in 1967, sticks to a strict selection of its candidates with initial examinations before admission to the definite exams, giving to each member a special training in its institute agreed by the government, and only grants the title of expert after a final control of his competence and knowledge, theoretical as well as practical.

Aware of the necessity to fit with the evolution of the Art Market, the C.N.E.S. spreads its representation through many other countries, by resident experts and correspondant members.

Founding member of the European Confederation of Fine Art Experts, the competence and rigour of the C.N.E.S. has developed the trust and confidence of private investors, collectors or international foundations.
