Since 1998, ATHOS, founded by Stijn Butenaerts in the heart of Brussels, has stood for legal expertise and reliability.
What began as a niche firm specialized in public and administrative law quickly developed into a recognized and trusted partner for public authorities, companies and private individuals.
Today, ATHOS is more than a law firm. We are a committed partner who thinks along, guides and defends. Our particular expertise in public procurement and administrative law remains at the core of our practice, but over the years we have broadened our services and assist clients across various areas of law.
Whether it concerns legal advice, negotiations or proceedings before the Council of State, the Constitutional Court, administrative tribunals or the ordinary courts, our team is ready to make a difference with dedication, sharpness and precision.
