The research will focus on the study of enforcement titles in cross-border enforcement within the EU. The research will contribute to a better understanding of differences in structure, content and effects of judgements in individual Member States. Furthermore, the impact of these differences on cross-border enforcement will be examined. Research will further focus on the differentiation of dogmatic and empirical concepts of different enforcement titles in the framework of recognition and enforcement. In addition, project team will analyse the importance of terminological barriers that occur during the course of cross-border enforcement. Likewise, an important part of the research will be the analysis of possibilities for overcoming obstacles to cross-border enforcement resulting from a technological progress.
