Article 5
Area of activity 1. Subject to paragraphs 2 and 3, a lawyer practising under his home-country professional title carries on the same professional activities as a lawyer practising under the relevant professional title used in the host Member State and may, inter alia, give advice on the law of his home Member State, on Community law, on international law and on the law of the host Member State. He shall in any event comply with the rules of procedure applicable in the national courts. 2. Member States which authorise in their territory a prescribed category of lawyers to prepare deeds for obtaining title to administer estates of deceased persons and for creating or transferring interests in land which, in other Member States, are reserved for professions other than that of lawyer may exclude from such activities lawyers practising under a home-country professional title conferred in one of the latter Member States. 3. For the pursuit of activities relating to the representation or defence of a client in legal proceedings and insofar as the law of the host Member State reserves such activities to lawyers practising under the professional title of that State, the latter may require lawyers practising under their home-country professional titles to work in conjunction with a lawyer who practises before the judicial authority in question and who would, where necessary, be answerable to that authority or with an 'avoué` practising before it. Nevertheless, in order to ensure the smooth operation of the justice system, Member States may lay down specific rules for access to supreme courts, such as the use of specialist lawyers.
