Altitude Avocats

What Altitude Avocats does

Altitude Avocats is an independent Paris-based tax law boutique founded in 2016 by Julien Bellet, headquartered at 20 avenue de Friedland in the 8th arrondissement. The firm is composed of four partners (Julien Bellet, Nicolas Canetti, Éric Chartier, Éric Ginter) and four collaborators, all admitted to the Paris Bar and operating as a traditional French cabinet d'avocats. It specializes exclusively in tax law, organized around three core service lines: patrimonial tax (structuring, optimization, and transmission of private and professional wealth), tax audit and litigation (defense in tax controls and representation before administrative courts), and international tax (cross-border situations, residence transfers, and European/community tax law). Supporting advisory capabilities include business transmission, management packages and employee stock plans, and real estate tax consulting.

The firm's underlying 'technology' is the technical expertise of its partners, several of whom hold dual qualifications (Paris and New York bar), include an ENA graduate with prior experience at the Prime Minister's office and DGFIP, and maintain active teaching positions at major universities (Paris II Panthéon-Assas, Paris Dauphine, ESCP Europe). The firm has no proprietary software, no patent portfolio, no API, and no AI tooling. It executes international mandates through a network of foreign correspondent law firms across Europe and beyond, and participates in the EU Tax Group think tank on European community tax law.

Altitude Avocats operates on a sales-led professional services model. The firm does not publish pricing; legal services are billed on engagement-specific terms (hourly or fixed fees) and are acquired through professional reputation, referrals from notaires, experts comptables, banquiers and other advisors, and thought-leadership content published on the firm's website and in legal journals. The client base is concentrated in France, with cross-border work routed through the foreign correspondent network. The firm is independently owned by its partners, with no parent company, no private equity or venture capital backing, and no subsidiaries. It has been recognized in the Leaders League 2025 ranking for 'Gestion de Patrimoine - Fiscalité du Patrimoine' and listed in the Chambers High Net Worth directory.
