The concept of European private law is currently used in two fundamentally senses. In a narrower sense, the European private law is in the context of the development of EU legislation considered as a relatively separate part of EU law.
It is at the national level usually treated by private law disciplines, particularly civil and commercial law. In this sense, the European private law is a set of standards reflecting the degree and level of integration, harmonization and achieved "acquis".
Nevertheless it can not yet be regarded as a separate legal domain and comprehensive regulation of private law, as it is usually in national legislation, since the EU private law pursues only the selected private issues.
