Janssen Advocaten

What Janssen Advocaten does

Janssen Advocaten is a Belgian law firm founded in 1935 and headquartered at Leopoldwal 6, 3700 Tongeren, Belgium, operating as a civil partnership (VOF) under the co-leadership of Yves Janssen and Dominique Janssen. The firm provides specialized legal services across nine practice areas: family and personal status law, family property and inheritance law, mediation and negotiation, liability and insurance law, criminal and traffic law, corporate and commercial law, construction law, contract law, and labor and social law. It serves two horizontal customer segments — private individuals (particulieren) and businesses (ondernememingen) — primarily in the Tongeren and broader Limburg region, with documented cross-border advisory capacity for Dutch clients. The team comprises eight specialized lawyers (Yves Janssen, Dominique Janssen, Caroline Pincemin, Hanne Nicolaers, Lauren Vaes, Céline de Bellefroid, Dries Geusens, plus one additional) supported by two administrative staff (Katja and Sascha), combining the responsiveness of a family business with the depth of a niche practice.

The firm's commercial model is hourly professional-services billing, with rates set per case based on complexity and urgency, an upfront deposit at case initiation, and a detailed final invoice upon completion. The GTM motion is sales-led and relationship-driven: the firm emphasizes personal approach, objective feasibility advice, and negotiated/mediated solutions before litigation. Multiple team members (Yves Janssen, Dominique Janssen, Hanne Nicolaers) hold certified mediator credentials covering family, civil, and commercial disputes. The firm is bilingual (Dutch/French) and maintains collaborative relationships with Dutch lawyers and Dutch damage settlement bureaus (schaderegelingsbureaus) for cross-border matters. The firm's value proposition rests on over 90 years of local presence, multi-specialty depth under one roof, mediator-led alternative dispute resolution, and bilingual case handling for Belgian-Dutch cross-border work.
