Trium Notarissen

What Trium Notarissen does

Trium Notarissen is a Dutch notary practice (maatschap/partnership) operating two physical offices in Culemborg (Rinkespad 1, headquarters) and Geldermalsen, serving the Betuwe region between Arnhem, Gorinchem, 's-Hertogenbosch, and Utrecht. The firm was established under its current brand in 2019 by consolidating two predecessor practices — Ton & Van den Broecke Notarissen (Culemborg) and Notariskantoor Swane (Geldermalsen) — and is staffed by approximately 10 people: two notaries (mr. P.K.J. van den Broecke and mr. H.J. de Boer), one candidate-notary (mr. L. van der Lijn), three notarial support staff, and one accountant.

The firm delivers the standard regulated Dutch notarial service set: residential property transfers and mortgage deeds, company formation and corporate restructuring (legal mergers, splits, acquisitions, shareholder agreements), marriage and cohabitation contracts, wills and estate administration, and divorce/notarial separation settlements. There is no proprietary technology stack; service delivery relies on regulated professional expertise, an 'Online Dossier' digital client portal (trium.online-dossier.nu), and shared tools inherited from parent network Netwerk Notarissen, including a network-wide AI knowledge assistant used for research and advisory.

Trium Notarissen is an independent member of the Netwerk Notarissen cooperative of approximately 154 Dutch notary offices, which provides knowledge sharing, peer review, joint training, network marketing, and centralised digital tooling. Revenue is generated on a professional-services fee basis through per-deed billing; pricing is not publicly disclosed and is obtained via a 'request price' workflow. The firm operates a direct-to-consumer go-to-market model with no disclosed external investors, parent company, or funding rounds.

Broad incumbents

• Loyens & Loeff: Benelux-headquartered law and tax firm with notarial capabilities, particularly in corporate and cross-border matters. Comparable as a Dutch notarial services provider but at international scale, competing for higher-end corporate mandates.
• De Brauw Blackstone Westbroek: Top-tier Dutch law firm that also handles notarial acts for major corporate transactions. Comparable as a Dutch notarial services provider, but at a much larger scale and focused on premium corporate and cross-border work rather than regional SME/private clients.
• Houthoff: Major Dutch law firm providing notarial services alongside its legal practice, particularly in corporate transactions. Comparable as a Dutch notarial services provider but operating at national and international scale.

Direct peers

• Hekkelman Notarissen: Mid-sized regional Dutch notary firm with comparable services in property, family and business law. Comparable to Trium as a similarly structured multi-office Dutch notary practice serving a regional client base.
• Netwerk Notarissen: The parent network of ~154 Dutch notary offices that Trium belongs to. Directly comparable because it operates the same notarial service model across the Netherlands, providing shared branding, knowledge, and quality standards to member offices.
• Dirkzwager: Dutch legal and notarial services firm with offices in the Randstad. Comparable to Trium in offering full notarial services (property, corporate, family) to a regional client base, though operating at a larger scale.
• Nysingh Advocaten – Notarissen: Combined Dutch law and notary firm providing notarial services across corporate, real estate and private-client matters. Comparable to Trium as a regional notarial practice with both corporate and private-client capabilities.
• Van Benthem & Keulen: Dutch firm offering notarial services alongside legal advice, headquartered in Utrecht. Comparable to Trium in service mix (property, corporate, private clients) and in serving clients in the central Netherlands.

Others
