Etude Sansonnens et Bossel

What Etude Sansonnens et Bossel does

Etude Sansonnens et Bossel is a private partnership law firm headquartered in Fribourg, Switzerland, operating from a single office at Boulevard de Pérolles 3. The firm is structured around two associate-partner attorneys — Benoît Sansonnens (Fribourg bar, FSA specialist in civil liability and insurance law since 2009) and Sébastien Bossel (admitted 2015, partner since 2016) — with a support team of approximately five administrative and junior staff. The firm provides traditional legal services across civil liability, insurance, family, succession, contract, administrative, criminal, labor, and social insurance law, serving both individuals (physical persons) and legal entities (moral persons) in the Canton de Fribourg. The firm's service offering is organized around four functional pillars: defense/representation, case management, legal counsel, and drafting of contracts and correspondence in French and German. For notarial acts, the firm collaborates with external qualified notaries rather than maintaining in-house capability.

The firm operates a traditional professional services business model with no proprietary technology, no AI-enabled products, and no software platform. Revenue is generated through fee-for-service legal billing with an emphasis on transparent invoicing and a provision/advance payment structure; legal aid (assistance judiciaire) is available for qualifying clients. The go-to-market is largely referral-driven, supported by a basic website, Google reviews, and partner involvement in BNI Chapter G&V Business. The firm is independently owned by its two partners, with no external investors, no funding rounds, and no M&A activity disclosed. There are no certifications, patents, or proprietary data assets; the technology stack consists of standard practice management and website infrastructure.
