Lawyer, notary and mediator :
A triple agent at the service of private law

As an associate notary from 2001 to 2018, I draw most of my know-how in the field, in the daily practice of a firm with 8 associates in the Eure region. In 2019, in support of the observation that private international law remains under-invested in the resolution of many cases, I decided to make it a speciality, to help my colleagues to take up the increasingly pressing challenge of an internationalisation of their practice. I then added two skills : that of a lawyer and that of a mediator. I can now intervene indifferently in cases of estate division, constitution or liquidation of matrimonial regimes, and any amicable or judicial resolution of cases involving the family, in all its components.

Mastering and passing on my favourite material: family law

By producing a range of enlightened legal solutions, I aim to guarantee the client a free choice of direction. Although I am less at the forefront of the client relationship, I keep the spirit of this humanist commitment, permeated with empathic listening, mainly at the service of the legal profession.
