By judgment of 18 December 2025, the Belgian Court of Cassation delivered a significant ruling in a disciplinary (disciplinary law / professional disciplinary proceedings) case against a real estate agent, with far-reaching consequences for the real estate profession.

The case concerned the scope of the disciplinary liability of a real estate agent practicing within a larger real estate group.
The Court expressly confirmed a cornerstone of Belgian professional disciplinary law: any natural person registered as a real estate agent with the Belgian Institute of Real Estate Agents (BIV / Institut Professionnel des Agents Immobiliers) is personally and individually subject to disciplinary jurisdiction and remains fully liable under the applicable deontological rules for his or her professional conduct.
Such disciplinary liability cannot be transferred to, diluted by, or absorbed into the legal personality, internal organization, or hierarchical structure of a organization within which the professional activities are performed.

The disciplinary court must assess the conduct of the individual who performed the act, rather than the organisational chart of the office.
This applies even where the agent:
For real estate offices and groups, this means that:
For clients, this means that:
The Court of Cassation thereby confirms a fundamental principle of the real estate profession:
Disciplinary liability is personal. Any individual acting as a real estate agent remains personally responsible for their conduct, regardless of the office or organizational structure in which they operate.
