The best of both worlds

« DUPONT–HISSEL » can therefore rely - whenever it serves its clients - on particularly solid institutions capable of providing a wide range of expertise. And, generally, a case or a negotiation in the professional sports sector requires a variety of skills: intellectual property law, company law, contract law, tax law, employment law, criminal law, etc.

Most of the international federations and the IOC have their headquarters in Switzerland. « DUPONT–HISSEL » has therefore developed an expertise in Swiss law, for which it also relies on two leading Swiss law firms,
« NATER-DALLAFIOR » and « INLAW associates ».

This structure is what makes « DUPONT–HISSEL » : so versatile and strong: combining the reactivity and specific expertise of a hyper-specialized firm with the work power and multidisciplinarity of large traditional law firms. In short, the best of both worlds.


« DUPONT–HISSEL » is able to handle cases in:

  • English
  • Spanish
