In the modern world of global economic and political associations, the knowledge of foreign languages and communication skills represent essential factors in all professions. In this respect, knowledge of English language as lingua franca of international communication is an indispensable prerequisite for communication within the legal profession worldwide. This paper is a case-study of teaching foreign languages in Croatian Law Schools, presented on the case of the Faculty of Law, University of Osijek. In the introductory part of the paper, a short description of the status and the position of foreign language courses in the Higher Education System of the Republic of Croatia is offered. In the main part the author presents new developments in the foreign language teaching in Croatian law faculties as answers to current challenges of Croatian membership in the EU. On the example of the Faculty of Law, University of Osijek, new projects on teaching foreign languages to practicing lawyers and law students are presented, with an emphasis on the Lifelong Learning Programme for Lawyer-Linguists. This programme, as well as specific foreign language courses in Legal English, Legal German and Legal French, have been developed within the lifelong education projects for lawyers, by which young lawyers are offered an opportunity to learn and/or to improve their knowledge of the three working languages of the EU. These developments in foreign language teaching within the Croatian Higher Education System are one of the responses to current challenges of the internationalization of the modern world.
