About us


ANDERSEN BALLÃO ADVOCACIA was founded in 1979, in the city of Curitiba, by lawyer Wilson José Andersen Ballão, shortly after graduating in Law from the Federal University of Paraná. The firm was created with the objective of providing high quality legal services, initially in the area of ​​International and Maritime Law, with individual and corporate clients, both national and foreign. In the mid-90s, the firm expanded its range of activities to meet the great demand arising from the high level of its services. Specialized departments were established for the main areas of law.
