Janson is a multidisciplinary and multilingual business law firm founded in 1950. Today, the firm has around one hundred lawyers, most of whom have completed their university studies with an LL.M or another university degree from Belgium or abroad.
Throughout its expansion, Janson has remained independent of other national and international law firms, but has maintained close ties with similarly committed independent law firms throughout the world.
In 2004, the law firm van Drooghenbroeck-Lagneaux, specialising in social law, merged with Janson. In order to be closer to its clients in the Flemish region, the firm opened an office in Ghent in 2011. The law firm Favart, based in Mons since 1957, joined Janson in 2017.
