Jeantet is a leading French business law firm since it was founded in 1924. The firm provides to clients the know-how and experience of its lawyers in the strategic areas of business law, both as advisors and litigators, covering a wide range of legal, tax and regulatory specialities. Aware of economic, technological, sectoral and legal developments, we develop reliable and practical solutions adapted to their challenges.

For four generations of lawyers, Jeantet has been recognised for its independence, its international dimension and its leading role on the economic and legal scene. As a "full-service firm", we are able to quickly assemble dedicated, multi-disciplinary teams that are able to adapt to the different situations faced by our clients. Our lawyers work in cooperation with leading academics and professionals in their field. The technical expertise that results from these exchanges characterises Jeantet's methods, creativity and legal excellence.


The Jeantet lawyers offer their clients high added value thanks to the know-how that they have developed as a primary result of their training and professional experience.

Our in-depth knowledge of our clients’ business sectors combined with our technical case-related expertise, enable us to offer innovative solutions to the issues we are asked to examine.

For our clients, we constantly monitor and anticipate changes in the law by comparing our approaches with academics and many experts who have a sound legal, economic, financial and labour-related background.


In addition to its ability to resolve the issues common to all players in the economic, financial and social sphere, Jeantet boasts specific expertise in certain sectors as a result of the training, experience and career paths of its lawyers. These sectoral skills are a major asset, the benefits of which filter through to its handling of the issues presented to our lawyers in other sectors.

We carry out ongoing monitoring in many fields, including legal, economic and social, and deepen this knowledge on a daily basis to ensure that we provide a rapid response in the way we deal with requirements immediately and in the solutions we offer our clients.


With 200 professionals in 6 offices and its network of "best friends" composed of the best foreign law firms, the firm is operational in more than 145 juridictions. As a result, Jeantet is able to represent its clients in cross-border litigation and assist them in all their international issues. With offices in Casablanca, Geneva, Kiev and Budapest, Jeantet is the only French institutional law firm fully integrated in these jurisdictions, offering a full range of services. Via its 3 strategic Desks (in Africa, Central/Eastem Europe - China), the firm is able to pursue an international development strategy in these high growth potential areas as well as in other countries deemed strategic for the firm.


We are continuing our growth strategy in Africa and the Middle East and in other countries that are considered strategic for the firm. Our activities in China also enable us to extend our influence to this part of the world.

About Our Clients

Jeantet advises major national and international groups in the industrial and service sectors, banks and financial institutions, investment funds, SMEs, the government, local authorities and professional organisations.


Our Infothèque (resources library) is a cornerstone of our firm’s development and know-how. The tools used enable our lawyers to keep abreast of changes in the business sectors and markets in which our clients operate in order to anticipate any potential issues these may pose. Our librarians create and manage many tools for use by our lawyers and clients in order to pass on knowledge and information in real time. Our databases, information gathering and media monitoring systems, newsletters, and legislative, regulatory and jurisprudential monitoring services are also made available to our clients. The wide range of transactions we carry out and our commitment to transparency towards our clients have prompted us to establish permanent monitoring tools to eliminate any risk of conflict of interest.


Our lawyers share the latest legal and legislative news in addition to their experiences, by organising training sessions for their clients on topical issues and major French and European regulatory developments.
