What Groupe Althémis does

Groupe Althémis is a French notary group (SPFPL) operating seven offices across France (Paris, Andrésy, Le Vésinet, Aix-en-Provence, Nantes, Lyon, and Collonges-sous-Salève) with approximately 140 notaries and collaborators. The firm delivers regulated notarial acts and complementary professional services across five core practice areas: Estate Planning (Patrimoine), Business Law (Entreprise), Real Estate (Immobilier), Family & Succession (Famille & Succession), and International. Its primary client segments are high-net-worth individuals and families, business owners and entrepreneurs, real estate investors and developers, professional and institutional investors, and international clients with French or cross-border assets. Revenue is generated through state-regulated notarial emoluments under decree n° 2016-230 and the arrêté du 26 février 2016, plus additional professional service fees for consultation, file audits, and specialised advisory work; pricing follows published transaction-based schedules with remissions of up to 40% on high-value transactions.

Operationally, the firm relies on the Septeo iNot platform (including iNot Compta & Talent) for case, document, accounting, and payroll management, and in 2025 launched an integrated online payment portal serving all seven offices. Internal mechanisms include cross-office working groups, a central documentation centre, and a quality service department that underpin consistency across the network. Distribution is exclusively direct and office-based — no digital-first product offering exists — with engagement led by partner notaries. As a founding member of the Lexunion international network of 500+ notaries, lawyers, and tax experts, and as organiser of the annual Rencontres Internationales Althémis conference (held since 2013 in partnership with LexisNexis and Sphère Événements), the firm positions itself as a specialist in cross-border estate planning and complex wealth, business, and real estate transactions for sophisticated French and international clientele.

Broad incumbents

Its scale and broader corporate bench make it a broad incumbent competitor rather than a direct specialist peer.
• Bredin Prat: Bredin Prat is a leading French corporate law firm whose private client and tax practice handles HNW wealth structuring, estate planning, and family business transfers. Its broader corporate M&A focus and larger bench place it as a broad incumbent relative to Althémis.
