Les Notaires du 51 Montaigne

What Les Notaires du 51 Montaigne does

Les Notaires du 51 Montaigne (legally SARL Jacquin & Associés) is a Parisian notarial practice headquartered at 51 Avenue Montaigne in the 8th arrondissement of Paris. It is a regulated French notary office (office notarial) offering legal services across four practice areas: family law (marriage contracts, PACS, divorce, successions), real estate (sales, financing, leases, development), wealth/patrimony engineering (donations, démembrement, Pacte Dutreil structuring, civil wealth companies), and corporate law (company creation, shareholder agreements, transfers, governance). The firm is staffed by 11 notaries — five associés (Rebecca Jacquin, Pascal Bonne, Benjamin Jacquin, Nicolas Ichou, Stéphane Ichou) and six notaires (Sylvain Jouve, Hortense Fontaine, Franck Cret, Olivier Haas, Muriel Mercier, Yves Clary, Isabelle Simeon) — supported by additional administrative personnel.

The firm operates as a regulated public officer practice, meaning most fees are set by state tariff (loi du 6 août 2015 and décret du 26 février 2016) on family law acts, real estate transactions, and successions, while corporate, commercial lease, and standalone advisory work is billed under free-fee convention honoraire. Its go-to-market is direct-to-consumer via in-person appointments at the Avenue Montaigne office, telephone consultations, and video conferencing for clients across France and internationally. Distribution is augmented through the NEGONOTAIRE network of 50 Parisian notary offices for property listings, and through the Art & Finance sub-brand co-founded by Rebecca Jacquin for HNW and art-collector advisory mandates. Customer acquisition relies on educational blog content, LinkedIn video, online fee/tax calculators hosted by notaires.fr, and verified Google reviews. The firm has multilingual capability (French, English, Spanish) and specialized expertise serving Near and Middle East investors, family offices, institutional real estate clients, and developers.

The practice is independently owned by its notary partners with no external investors, no parent company, no disclosed funding history, and no subsidiaries. It has been built incrementally since at least 1989 (Pascal Bonne's original Rambouillet practice), with key partner additions in 1997 (Nicolas Ichou), 2008 (Pascal Bonne, Nicolas Ichou as associates), 2011 (Benjamin Jacquin as partner), and 2022 (Isabelle Simeon).

Direct peers

• Loffi & Associés: Parisian notary practice structured as an étude with multiple notaires offering real estate, family and corporate services. Closely comparable in size, multi-notary structure and central-Paris positioning.
• Cheuvreux Notaires: Large multi-office Parisian notary practice offering family law, real estate, corporate and wealth-engineering services to a comparable HNW and institutional clientele in Paris. Directly comparable in service mix and client profile.
• 14 Pyramides Notaires: Parisian notary study offering comprehensive family, real estate and corporate services with a partner structure similar to Les Notaires du 51 Montaigne. Direct competitor for Paris residential and commercial transactions.
• Alerion Notaires: Paris-based notary office covering real estate, family law, corporate and estate planning with a comparable mid-to-large multi-notary structure. Competes directly for the same Parisian HNW transaction flow.

Others

• Notaires de France (Conseil Supérieur du Notariat): National professional body governing all French notaires and operating the public notaires.fr portal (including the calculators Les Notaires du 51 Montaigne links to). An ecosystem participant rather than a competitor, but shapes the regulatory and digital infrastructure in which the firm operates.

Broad incumbents

• Bignon Lebray Avocats: Multi-office French law firm with strong real estate, corporate and private wealth practices. Comparable to Les Notaires du 51 Montaigne in serving HNW and SME clients but operates under the avocat (non-notaire) regime with a broader national footprint.
• Fidal: Largest French business law firm with a national network of offices, providing corporate, tax, and wealth-planning legal services. Overlaps with the firm's Droit des Sociétés and Ingénierie Patrimoniale practices but at much greater scale and broader scope.

Regional players

• NEGONOTAIRE: Network of 50 Paris-region notary offices co-animated by Les Notaires du 51 Montaigne for real estate. Both a channel partner and a quasi-peer set: the individual member offices compete for the same regional real estate transactions while collectively forming the firm's distribution platform.

Emerging players

• CNotaires: Digital platform aggregating French notaires for online appointment booking and service comparison. An emerging player that could divert top-of-funnel demand away from traditional practices like Les Notaires du 51 Montaigne that lack comparable proprietary digital infrastructure.
