Abstract: An essential part of contemporary international civil law practice consists of matters concerning succession of multijurisdictional estates, which in turn accounts for the practical significance and relevance of the scientific study of the regulatory treatment of the respective matters. An understanding of the subject matter of conflict of laws and international civil procedure is essential to effective succession of international estates for clients who own assets in or otherwise have significant contacts with more than one jurisdiction. The primary focus of this article is to describe the approaches to resolving the most typical problems in the practice of succession of multijurisdictional estates on the basis of analysis of the legal doctrine, legislative enactments and case law of foreign jurisdictions. The author considers the approaches to solving the most typical problems of succession of multinational estates, in particular: the practical importance of the location of a testator's assets, the formal validity of testamentary dispositions, establishment of the true domicile of a person, the advantages and disadvantages of a single multijurisdictional will disposing of international property, etc. In the context of these problems the author analyses Regulation EU № 650/2012 of the European Parliament and of the Council of 4 July 2012 on jurisdiction, applicable law, recognition and enforcement of decisions and acceptance and enforcement of authentic instruments in matters of succession and on the creation of a European Certificate of Succession; Convention of 5 October 1961 on the Conflicts of Laws Relating to the Form of Testamentary Dispositions; Convention of 25 November 1973 providing a Uniform Law on the Form of an International Will.
