DWMC has built up a particularly strong practice in advising professional and lobby associations based in Belgium.

We assist these associations with their constitution and advise them on all legal issues affecting the exercise of their activities, including issues of association law, European and competition law, commercial law, social law (including immigration issues), tax law, intellectual property and data protection.

In particular, we assist associations in :

  • choosing the most appropriate corporate structure (ASBL, AISBL, foundation) and the constraints in terms of governance and management;
  • drafting articles of association and internal rules so as to adapt them to the functioning of the association and/or align them with best practices adopted by other Brussels-based associations;
  • compliance with anti-trust rules, training in competition law and, in general, all matters relating to European and competition law;
  • restructuring of associations (national and cross-border mergers and demergers and liquidations);
  • registering with the European Transparency Register;
  • data protection law issues, including compliance with the General Data Protection Regulation (GDPR);
  • labour and social security law (including issues relating to immigration and international mobility of workers);
  • tax law (including VAT and cross-border transactions);
  • intellectual property rights (including trademark protection of the association's name and licensing).

We have also developed a Corporate Housekeeping department, which deals with the publication of decisions taken by the associations (composition of the board of directors, change of registered office, etc.) and the obligations regarding (Ultimate Beneficial Owners (UBOs), as well as the coordination of the intervention of the notary when this is legally required.

Finally, we monitor legal developments on an ongoing basis and inform our clients of significant legal developments.

Our team is headed by Alain Costantini, who has developed a unique practice focused on professional and lobby associations since 1994 and is one of the most experienced and recognised specialists in this field. He regularly advises more than 40 associations and is an associate member of FAIB since 2005, the Federation of European and International Associations established in Belgium (www.faib.org).
