For more than twelve years, we have been regular counsel to diplomatic missions in Brussels.

Our “Diplomatic Desk” is dedicated to providing legal services to diplomatic missions and to representing them and their members before the Belgian authorities and courts. It offers a wide range of services on all legal matters related to diplomatic missions and their members, contemplated in the Protocol Guide on Immunities and Privileges published by the Belgian Federal Public Service of Foreign Affairs, Foreign Trade and Development Cooperation (special rights enjoyed by privileged persons derived from the 1961 Vienna Convention on Diplomatic Relations, the 1963 Vienna Convention on Consular Relations and the Headquarters Agreements entered into with international organizations present or represented in Belgium).

We are familiar with the specific legal needs of diplomatic missions. In our approach, we want to offer a comprehensive service that covers all legal issues that diplomatic missions, their diplomats and families may face in Belgium.

Depending on the specific requirements of a diplomatic mission, we usually agree on an annual all-inclusive budget, but we are also open to being compensated for each service provided.

The Diplomatic Desk is headed by Thierry Ongenae who, thanks to his in-depth experience with diplomatic missions since many years, is able to offer a particularly professional, practical and competitive service in this area.
