Abstract
Article deals with the problem of the harmonisation and unification of the family law in the European Union as the consequence of the building the single European Space. Th e main claim of the author is that a speedy unification of substantive family law, particularly one that is decreed by European institutions, would lead to loss on national and regional legal culture, what accorfing the author can’t be justified. Th e alternative is a close cooperation of individual European cultural groups or neighboring countries and the unification of the conflict of laws provisions and of the law of jurisdiction of the courts as well as by enacting regulations on (mutual) recognition and enforcement of court decision.
