PlasBossinade

What PlasBossinade does

PlasBossinade Advocaten en Notarissen is a Dutch full-service law firm and civil-law notary office headquartered in Groningen, with additional offices in Leeuwarden, Rotterdam, and Haren. Founded around 1900 and operating for over a century, the firm is organized around two core divisions: Advocatuur (Advocacy) spanning 25+ practice areas including corporate law, employment law, M&A, construction law, tax, IP, insolvency, and criminal law; and Notariaat (Notary) covering commercial real estate, family and inheritance matters, residential property transactions, company formation, and shipping documentation. The firm additionally offers specialized expertise in regional niches such as Groningen-region earthquake-related matters, WHOA restructuring, maritime law, mediation, and government practice.

The business model is professional services-based, generating revenue through hourly billing for lawyer services (rates varying by seniority and case complexity, charged monthly in arrears), fixed pricing for notarial deeds, and alternative fee arrangements including blended rates, subscriptions, helpdesk functions, and fixed-price agreements for defined matters. Customer segmentation is hybrid, with two primary segments: medium-to-large enterprises requiring cross-disciplinary legal support, and private individuals needing personal legal and notarial services. Distribution is sales-led through direct in-person consultations at the four office locations, supplemented by a content-marketing layer (newsletter, blog, publications, knowledge events) and partnerships such as the cooperation with Rotshuizen Geense Advocaten and joint events with Rabobank.

There is no proprietary technology platform; the firm operates as a traditional professional services organization. As of January 1, 2026, PlasBossinade and Rotshuizen Geense Advocaten formally merged and continue operations under the PlasBossinade name, consolidating their presence across the Northern Netherlands market.

Revenue model

1. Legal Services - Hourly Billing: Fee for activities carried out by lawyers is based on hourly rates, appearing to be the most realistic and transparent fee structure. Activities are charged monthly in arrears with specification showing which activities were carried out and time spent.
2. Notarial Services - Fixed Pricing: For notarial deeds, fixed prices generally apply. Quotations can be requested via website or per e-mail. Specialized advisory activities in which the notarial deed is part of a more comprehensive transaction are charged similar to lawyers' fees.
3. Alternative Fee Arrangements: Alternative arrangements including blended rates (fixed hourly rate for all legal matters), subscription (fixed annual fee), helpdesk function, and fixed price agreements for specific cases or activities.
