Kooijman Autar

What Kooijman Autar does

Kooijman Autar is a Dutch notary partnership (maatschap) headquartered at Straatweg 7 in Rotterdam, offering notarial, mediation, and legal advisory services in civil law. The firm's history traces back to 1869, with the Kooijman name associated since 1947 and third-generation notary Peter Kooijman currently practicing. The firm operates across five practice areas: Family and Succession Law (relationships, matrimonial law, wills, inheritance, tax planning), Real Estate and Mortgage (property transfers, financing, rental and management), Estate Planning (asset management, financial planning, legal structures), Company Law (business formation, M&A, business succession), and a specialized Ships and Aircraft niche (maritime and aviation registration, mortgages). Approximately 30 staff are employed, including three notaries, six junior notaries (kandidaat-notarissen), one notary clerk, and 20 other professionals.

The firm runs on a traditional professional services operating model, with revenue generated through hourly fees or fixed office tariffs for deeds and advisory work, plus pass-through disbursements (cadastral fees, court fees, levies). Distribution is exclusively direct-to-consumer via in-office appointments, supplemented by a free weekly Thursday walk-in consultation (17:00–18:00), a monthly newsletter, and a multi-platform social presence. The technology stack is modest: a digital vault for secure document storage and digital tools for estate administration, but no AI/ML features, no mobile app, no public API, and no integrations. Kooijman Autar holds memberships in KNB (the Royal Notary Professional Association), EPN (Estate Planning Netwerk), NICO Notarissen, VMN (maritime notaries), and VON (corporate notaries), and maintains a charitable giving program supporting Rotterdam-area cultural and civic institutions.

The customer base spans three primary segments: high-net-worth individuals and families (often multi-generational clients seeking estate planning, wills, and matrimonial arrangements), SMEs and entrepreneurs (formation, governance, M&A, business succession), and real estate buyers/sellers/investors. Services are predominantly one-time engagements tied to legal events, though ongoing advisory relationships exist with long-tenured clients.
