Introduction

Who am I?

Following a career in the private sector and in law firms, I founded UGGC Avocats – with other lawyers – in 1993.

From the onset, my foremost speciality is the law of company transfers (what some posers call M&A), providing advice or assisting with litigation, but also deal with the management of the personal assets of wealthy families and I am involved in arbitration, international in particular.

I am also involved in professional associations and organisations (ACE…) and I am currently President of the UIA.

UGGC and I

After many years I still enjoy doing my job as a lawyer with the same pleasure because it is different from other jobs in that you can deal with a case from start to finish.

This is probably a satisfaction which is common to all lawyers but what I am personally proud of, apart from creating this firm, is to meet former interns, 10 or 20 years on, and to hear them say what pleasure they had working with us.

My practice

I am particularly involved in the agri-food and public work sectors, but my job encompasses a much broader area than these sectors.  In fact, my practice is both international and multidisciplinary at the same time since it covers international arbitration as well as transactions governed by OHADA law or more traditional transactions of business law.
