The article carries out a theoretical and legal analysis of the concept and criteria of legal globalization and its impact on national legal systems, stages of its formation, features, classification criteria. Various views on the periodization and reasons for the formation of globalization processes are presented, the main ones being information technologies, which fundamentally change the entire system of socio-economic relations, transfer organizational-economic relations, transport and communication links to a qualitatively new technical level; aggravation of problems that are common to all people and countries of the world and important from the point of view of the preservation and development of human civilization. The well-founded opinion that globalization is a complex, multifaceted, multidirectional process, as a result of which there is a strengthening of relationships between the natural and social world, between countries and peoples, cultures and states, as well as between individual individuals. The forms and methods of the effect of globalization on the political and economic, legal and social life of states and peoples are considered. A classification of global problems that contribute to legal globalization and require the unification of efforts of all subjects and the development of joint solutions is proposed. The main directions of its influence on the legal sphere are analyzed: universalization and unification of law. The main direction of the influence of globalization on law is its universalization, which consists in the development of common basic principles and institutions of law, the elimination of contradictions between national legal systems. In turn, law becomes an important (valuable) tool of globalization, since the absence of a single legal field, its lack of formation (contradiction) slows down globalization processes in various spheres of formation and functioning of world society. In addition, law acts as the main ideological basis of globalization, which is designed to contain the negative aspects and consequences of globalization. It is concluded that the growing trend towards international legal globalization contributes to the emergence of new principles and norms of law, the establishment of which previously belonged to the sphere of internal affairs of sovereign states. This significantly updates the state and legal systems of the members of the world community in the context of modern universal standards. The globalization of law itself, the progressive development of universal properties, norms, forms and procedures of the legal type of social life is a necessary stage and demonstrates the ability of law to regulate the processes of societal globalization within the framework of the general legal world order. Key words: globalization, legal globalization, integration, legal integration, internationalization of law, legal convergence, reception, harmonization, unification of law, universalization of law, standardization of law, norms of international law, norms of national law, legal system, world legal order.
