What Wargny Katz does
Wargny Katz is a Paris-based notarial practice (Étude WARGNY KATZ) founded in 1999 by Hubert Wargny and Alain Katz, specializing in corporate (tertiary) real estate transactions in France. The firm operates from 9 avenue Matignon in the 8th arrondissement and is staffed by approximately 50 collaborators, including six managing partners leading the practice since the founders' transition in 2020-2023 and a salaried notary bench expanded by seven new admissions in July 2022. Its core service lines cover investment property transactions, real estate financing, town planning and development, and an international division coordinating cross-border mandates.
The firm's primary product is WKWebspace, a proprietary in-house document-sharing and data-room platform developed to optimize the collection, management, and secure delivery of information across pre-contractual, due diligence, and Q&A phases of a transaction; it supports electronic data rooms and integrates document-exchange workflows with the firm's notarial service delivery. A wholly-owned subsidiary, Matignon Notaires, was established in 2020 at 15 avenue Matignon to serve private clients and mid-cap institutional mandates.
Wargny Katz generates revenue through regulated French notary fees (émoluments) governed by Décret n° 2016-230, which prescribe fee schedules with mandated remissions for larger transactions across property sales, financing, leases, and donations. The go-to-market motion is enterprise field sales: senior partners cultivate direct relationships with major institutional investors, French property companies (foncières), OPCIs, foreign investment funds, banking institutions, and developers, and execute mandates on large-ticket commercial real estate deals. The firm is privately held by its partner-notaries with no external equity or capital-raising activity.
