Who we are?

BMHAVOCATS : a global vision, tailor-made strategies.

Co-founded in Paris in 1988 by Detlev von Breitenstein and Martin Hauser, BMHAVOCATS is an independent, multidisciplinary business law firm that brings together twenty lawyers, including ten partners. In France as well as internationally, BMHAVOCATS assists investors, companies and innovative entrepreneurs in developing their projects and resolving their conflicts.

We offer tailor-made solutions that are the fruit of a global vision and a daily, personalised commitment to serving our clients.

Our Fundamental Values

Multicultural approach

Multicultural approach.
German in origin, BMHAVOCATS has evolved in an increasingly international context. Today, our lawyers, all multilingual, accompany their clients in Europe and all other continents. In order to take up this challenge, we combine our pluridisciplinary and multicultural expertise with the knowledge of transnational environments and a worldwide network of independent patners.


For us the human aspect comes first.
BMHAVOCATS is a law firm on a human scale. Our size nourishes the drive for closeness to which we are particularly attached. Because quality contact is the key to a successful collaboration, we develop enduring, privileged relations with our clients, based on  responsiveness and trust.


We are there for you.
Our commitment to you goes beyond legal support. The quality of our counsel is based on our involvement and availability. For us, a perfect understanding of your company is the determining factor of superior-quality service.

A proactive approach

We don’t just respond to your needs, we anticipate them.
Knowing your environment perfectly enables us not only to respond to your objectives over the long term, but also to anticipate your needs. Managing deadlines, rapid mobilisation and execution are the key words of our commitment at your side.


We play as a team.
The complementary nature of our professional backgrounds, our skills and our experience nourish the life of BMHAVOCATS on a daily basis. United around a shared conception of the profession, we favour teamwork and the synergies capable of bringing forth the legal solutions best suited to your needs.


We do not stop at a merely technical solution.
We all share a passion for our profession. That is why we do not deliver “standard” strategies. Each situation is unique and requires a pragmatic and innovative response. In order to perfectly respond to your objectives, we conceive “tailor-made” legal solutions. We put our creativity in the service of our legal expertise.
