Use of professional titles
Article 52
1. If, in a host Member State, the use of a professional title relating to one of the activities of the profession in question is regulated, nationals of the other Member States who are authorised to practise a regulated profession on the basis of Title III shall use the professional title of the host Member State, which corresponds to that profession in that Member State, and make use of any associated initials. 2. Where a profession is regulated in the host Member State by an association or organisation within the meaning of Article 3(2), nationals of Member States shall not be authorised to use the professional title issued by that organisation or association, or its abbreviated form, unless they furnish proof that they are members of that association or organisation. If the association or organisation makes membership contingent upon certain qualifications, it may do so, only under the conditions laid down in this Directive, in respect of nationals of other Member States who possess professional qualifications.
