Marc Abenhaïm, founding partner, graduated from the prestigious College of Europe and is a member of the Brussels Bar.

Marc is an accomplished lawyer with a deep understanding of EU law in general, and competition law in particular.  Before starting his own practice, Marc trained and worked as a Senior Associate with several leading international law firms (such as Sidley Austin LLP, Willkie Farr & Gallagher LLP and Van Bael & Bellis).

Each time, he gained an additional insight into the legal business and the variety of internal processes which lead to the best possible outcomes, in an extremely competitive environment.

Marc now translates his decade of professional experience into tailor-made, top-quality and cost-efficient legal services.

Small is beautiful

Size certainly matters in the legal world.  And that is exactly why we choose to be a small boutique. 

Aside from the inherent cost-efficiencies, our direct and straightforward approach to communication helps us provide our clients with a great level of flexibility.  Also, in an increasingly complex legal environment, the “horizontal” approach of a well-rounded legal mind very often fosters the quick delivery of integrated legal solutions, keeping in line with all types of clients’ expectations.  And where a given matter so requires (e.g., multi-jurisdictional merger filing, complex merger filings before the Commission, pan-European follow-on damages litigation, etc.), we – of course – rely on the capabilities of our trusted counterparts across the globe.

Our approach simply favors a lesser degree of economic integration, so as to ensure that each and every legal mind contributing to our output does so with the most pertinent expertise, and the utmost independence.


Because he is convinced that legal practice and legal thinking mutually enrich other, Marc Abenhaïm has always strived to maintain close ties with the academic world.

Among other scientific engagements, Marc has been teaching at the College of Europe in Bruges, the University of Paris X-Nanterre, and the University of Paris-Saclay.

He has also been coaching the College of Europe team during the European Law Moot Court competition (2013).

Marc was also widely published in numerous legal journals.
