I own a home. The administrator yesterday informed us that for the adaptation to the GDPR every administrator and every tenant and / or owner must attend a course for EVERY condominium administered. (repetita iuvant?) I believe, but I am not very expert in this area, that the certification for the administrator is a binding condition for the performance of the professional activity. Among other things, the administrator tells us that the cost is borne by the tenants/owners. Can you please give me some explanations?
