Practice under the home-country professional title
Article 4
1
A lawyer practising in a host Member State under his home-country professional title shall do so under that title, which must be expressed in the official language or one of the official languages of his home Member State, in an intelligible manner and in such a way as to avoid confusion with the professional title of the host Member State.
2
For the purpose of applying paragraph 1, a host Member State may require a lawyer practising under his home-country professional title to indicate the professional body of which he is a member in his home Member State or the judicial authority before which he is entitled to practise pursuant to the laws of his home Member State. A host Member State may also require a lawyer practising under his home-country professional title to include a reference to his registration with the competent authority in that State.
