This article is an attempt at a comprehensive legal analysis of current problems of civil law in the fields of contemporary law of Ukraine. With regard to cross-industry links, legal doctrine is defined as relations of interdependence, conditionality and commonality between different legal sectors, including their individual parts. In particular, the problems of correlation of civil law of Ukraine with other branches of law, such as labor law, business law, administrative law, criminal law, information law, financial law, are considered. Considering the problems of civil law in the context of modern law, the connection between private and public in civil law of Ukraine was highlighted. It has been concluded that scientists have for many years regarded civil law as a basic component of private law, and in some cases even identified it. At the same time, both the branches of private law and the branches of public law are recognized as components of the unified system of law of Ukraine, and, accordingly, they cannot exist completely autonomously from each other. All areas of law interact and interact. It was possible to distinguish the civil law of Ukraine from other basic branches of the system of Ukrainian law, and to draw some conclusions about the recognition of the civil law of Ukraine as a complex branch of law. Civil law terms and concepts used in other areas of law, relevant industry codes or other regulatory issues were also considered. The cross-sectoral links of civil law, which are not only limited to the legislative sphere, but also the cross-sectoral links at the level of enforcement are highlighted. This article stated that in order to achieve a stable and efficient functioning of the legal system, as a component of the domestic legal system, it is possible, subject to fruitful cooperation of the legislator, theorists and practitioners, their main task – to justify and develop a single organic complex of balanced branches of law. That is why special attention should be paid to the interaction of civil law with other branches of Ukrainian law, in particular, to determine the points of their contact, permissible situations and limits of mutual influence. The tendency to expand the sphere of civil law is reflected in the domestic law enforcement practice, which is reflected in the actual extension of civil law structures to public rights, the judicial protection of which affects the rights and obligations of a private nature (in particular, it concerns a tax lien, financial credit, etc.). It is concluded that the system of civil (private) law should be characterized as clear criteria for boundaries of action and separation from related fields (industries). Public law, defined by the codes of the relevant sphere (branch) of law, and take into account the tendencies of development of relevant spheres of public relations by means of norms capable to create inter-sectoral links with public-law norms in the framework of complex legislative acts.
