Founded in 1992 by Jean CHEVRIER, CHEVRIER AVOCATS Lawfirm, which has been acting for the aviation industry for thirty years, became MAZOYER GUIJARRO AVOCATS Lawfirm in 2022.

The background and experience of each of the firm’s lawyers, together with their in-depth knowledge of the operational and commercial challenges facing a regulated industry, enable us to meet our clients’ expectations with regard to a variety of issues and statuses and to intervene before all courts, whether civil, criminal, administrative, commercial or arbitrational.

In this context, our firm is sought for cases relating to major air accidents, commercial aviation, business aviation and light aircraft for sport and leisure, for out of court settlement, legal action or mediation.

We advise French and foreign airlines, ground handling operators, aircraft and aircraft equipment manufacturers, freight forwarders and their insurers, as well as assisting with expert opinion on technical matters, whether for out of court settlements and legal proceedings.

We also provide counsel and litigation services to French and foreign airports, particularly in matters of governance, liability, land in the public domain, competition law, safety and airport charges.
