Sauer & Oonk Adviseurs & Notarissen

What Sauer & Oonk Adviseurs & Notarissen does

Sauer & Oonk Adviseurs & Notarissen LLP is a privately held Dutch notary firm (LLP) headquartered in Vlissingen with a second office in Goes, both in the Zeeland province of the Netherlands. The firm offers a full-service notarial and advisory practice covering real estate transactions (purchase, sale, inheritance, transfer tax, family mortgages), estate and inheritance services (wills, gifting, estate administration, inheritance and gift tax), family law (cohabitation, marriage, registered partnerships, separation), business law (company formation including BV/NV/cooperative, restructuring, mergers, splits, share transfers, UBO registration), foundation and association formation (including ANBI status), and signature legalization with apostille handling. It also produces educational brochures, checklists, and animated explanations for clients, including a German-language track for cross-border clients.

The underlying delivery model is human-expertise-driven rather than technology-driven: service is executed by approximately 40 staff comprising 3 notarissen, 5 kandidaat-notarissen, and additional HBO/WO-qualified legal professionals (notarieel juristen) and administrative staff, organized by practice area. A digital Klantenportaal (client portal) supplements in-person service for document exchange and communications, and the firm publishes a Dutch-language content website, newsletter, and LinkedIn/Facebook/Instagram channels for top-of-funnel demand generation. The firm operates under the "Nationale Notaris" brand label (a national notary network/affiliation) and is GDPR-compliant with a registered Data Protection Officer.

Commercially, Sauer & Oonk generates revenue through professional-service fees on a predominantly hourly-rate basis with fixed fees agreed by contract in some cases; a published benchmark of EUR 120 (incl. VAT) per signature applies to legalization, and advance payments may be requested. Customer acquisition is direct-to-consumer and direct-to-SMB via two physical locations plus the website quote request flow; customer segments are Dutch individuals and families (primary) and Dutch entrepreneurs and businesses (primary), with foundations/associations and German-speaking clients as secondary segments. Headcount is reported in the 11–50 band ("Ruim 40 medewerkers"), the entity is unlisted, and no external funding rounds are disclosed.
