The Parlex Group

DELSOL Avocats’ international strategy relies on:

  • qualified teams from top French and foreign universities and schools, operational in various languages and registered with foreign bars.
  • extensive experience in negotiating and drafting international contracts.
  • access to reliable networks representatives renowned in their fields of expertise and sectors.

DELSOL Avocats assists its clients facing international issues, either French clients with international projects or foreign clients involved in operations in France. We are able to:

  • coordinate their projects (multi-country due diligence or acquisition of targets operating in several countries)
  • help them understand international (for our French clients) and French (for our international clients) legal practices and assist them in negotiating and drafting investment contracts and industrial or business partnerships
  • settle litigation or pre-litigation issues
  • act as an intermediary for their own international advisors.

DELSOL Avocats is an active member of two international networks: TELFA and PARLEX. The firm has therefore made strong connections with « best-friends » located in Europe, the USA, South America, Asia, Africa and the Middle East. There are now nearly 100 law firms, or about 7000 lawyers around the world.

DELSOL Avocats has built on the proximity of his Lyons office with Italia to create an « Italian desk » and thus inject dynamism into its transalpine activities relying on several bilingual partners and associates.

CLIENT: Jean-Sébastien DEGOUVE, Chairman
COMPANY/FIRM: Opéra Energie
TESTIMONIAL: I knew that DELSOL Avocats was well grounded in the energy sector, as I had called on the firm’s services during my time with the Suez Group (Engie). Therefore it was only natural for us to turn to Emmanuel KAEPPELIN for our M&A needs.

COMPANY/FIRM: MediaSchool Group
TESTIMONIAL: Because of the dual nature of our activity, we often come up against issues of employment law (permanent employees, occasional lecturers, journalists etc.), real estate law (the need for our school premises to comply with public access building (ERP) standards), tax law (particularly as regards VAT exemptions for training) and company law (company creations, M&A, transformations). We are highly satisfied with the advice we have received from DELSOL Avocats over a number of years, and particularly that of Henri-Louis DELSOL, Séverine BRAVARD and Vincent GUEVENOUX. In the course of successive acquisitions, the pertinence of the firm’s counsel within often tight timescales and its ability to identify with the position of the business client have proved invaluable throughout such operations, across the whole spectrum of the issues we face.

CLIENT: Nicolas POTEL, General Counsel, France & West Mediterranean Region
TESTIMONIAL: We have worked with DELSOL Avocats for a number of years, and more specifically with Stéphane PERRIN, who has been familiar with our business, its products and its legal issues for close on 30 years. We have built up a bespoke working relationship with him that combines responsiveness and competence, and this support and advice is essential in both Group litigation in France and in complex contractual issues.

CLIENT: Sophie DOSTERT, General Manager
COMPANY/FIRM: Hôpital Européen and Hôpital Saint Joseph de Marseille
TESTIMONIAL: Our recent experience comprehensively confirms the considerable skills of Xavier DELSOL and his teams, who swiftly helped to set up the legal framework for the merger process by reviewing the various possible scenarios.
