Yann Soyer – Partner

Even more importantly than being a man of integrity and conviction, a lawyer is by definition a confidant and must be a good listener. Any action that is not properly thought through is just agitation

For more than thirty years, I have been advising and defending, in close association with their general management, French and foreign businesses, listed companies, institutional investors, real estate developers, logistics firms, car dealerships, fashion houses, associations, court administrators and representatives, professional regulatory bodies, colleagues and individuals.
