The firm has been completely independent since its start in 2003 and shares the entrepreneurial spirit of its clients.

We employ renowned attorneys within their fields of expertise. 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’ advisors in other areas of activity every day : specialists in other fields, 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, we now have eighteen partners and a total of about sixty lawyers.

At first, the firm decided to concentrate on the principal areas of business law before adding new services in accordance with 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.
