Abstract
Cross-border mergers are regulated by the Directive 2005/56/EC of the European Parliament and of the Council of 26 October 2005 on crossborder mergers of limited liability companies. This article deals with the issue of cross-border mergers of limited liability companies within the internal market of the European Union, more precisely it analyzes the question of the concept of a cross-border merger under the European Union law and its implementation into the national legal order of the Slovak Republic. The legal definition of a cross-border merger under the European Union law comprises three key conditions that must be met cumulatively: cross-border merger is applicable only for a business company formed in accordance with the law of an EU Member State, having its registered office, central administration or principal place of business within the Community, and at the same time business company must be in an eligible legal form and a cross-border element must be given.
