The firm has been completely independent since its creation in 2003 and shares the company philosophy of its clients.

It employs specialists renowned for their area of expertise in France and abroad. Based in Paris, the firm represents clients who are expanding internationally or foreign clients investing in France.

Alerion favours an inter-professional approach. The partners converse with their clients’ advisers in areas of activity every day : specialist colleagues in other spheres, chartered accountants and auditors, investment bankers, consultants, notaries, property experts, etc.


Alerion was created in 2003 by six partners and had eleven employees.

Constantly growing, it now has 16 partners and a total of about sixty lawyers.

At first, the firm decided to concentrate on the principal areas covered by business law before adding new services according to the needs of the market.


The firm works for a wide variety of clients (large French and international groups, French subsidiaries of large international groups, listed companies or small and medium-sized businesses, start-ups, investment funds, associations, public institutions, local authorities, family offices, etc.).

Although the firm’s departments work together every day, sometimes in support of one another in certain operations, they have all developed an autonomous activity for clients who want the benefit of specialised knowledge.
