Dominique Heintz



Dominique HEINTZ, attorney with the Paris Bar and with the Brussels Bar, was a founding partner of the HWH firm in 1988.

He practices principally in the fields of competition, distribution and industrial risks law on behalf of a clientele comprised of French and international, notably German, companies and major groups. German-speaking, Dominique Heintz has in fact developed special relationships over 30 years with German companies and their French subsidiaries. He advises his clients with respect to complex subjects related to restrictive competition practices, merger control, antitrust, complex commercial contracts, industrial risks and insurance law. He represents their interests by means of lobbying of public powers and also assists them in their lawsuits. He has recourse to alternative dispute settlement when strategically required: mediation and arbitration. Dominique Heintz is very involved in the representative institutions of the legal profession. He has also been one of France’s foreign trade advisers since 2012.
