ALTIUS is one of the largest Belgian independent law firms, consisting of approximately 65 lawyers. Established in Brussels, Antwerp, and Louvain-la-Neuve, we advise Belgian and international companies on the legal aspects of transactions, projects and disputes.

We help our clients navigate through often-complex legislation and regulatory environments and provide clear solutions to a wide range of legal issues. In addition to our specialist legal knowledge, we focus on thinking creatively with our clients to offer tailor-made solutions. Our aim is to turn, through careful listening and awareness, strategic questions into clear, straightforward answers.

For tax-related issues, ALTIUS works closely with Tiberghien, a leading independent Belgian firm that specialises in tax law.
