The article discusses the impact of the EU Succession Regulation on the German system of private international law. The change came with some important differences introduced in the text of the Regulation as in comparison to previous German solutions (especially the use of the habitual residence as the main connecting factor instead of nationality), and, as a result of the number of decisions of the CJEU on the Regulation (in particular the Kubicka case). The paper presents the most important, up-to-date German case-law relating to the EU Succession Regulation. It starts with the general remarks in that regard and continues to discuss judgments covering issues of jurisdiction, applicable law, and the European Certificate of Succession. Three conclusions are drawn therefrom. First, the cases show a general willingness of the courts to cope with the fundamental changes introduced by the Regulation. In particular, the concept of “habitual residence” is applied on the basis of an autonomous interpretation by reference to the case-law of the CJEU on Regulation Brussels IIa. Second, a number of decisions make apparent that the courts are sometimes slow to accept the consequences which flow from the changes brought about by the Regulation, and which oblige to re-consider the German practice in matters of international successions. That applies in particular to the issuing of the European Certificate of Succession. Third, German courts are generally ready to initiate cooperation with the CJEU by formulating preliminary questions (three questions posed by the end of 2019).
