Introduction. In the whole world, all countries are involved to varying degrees in the process of digital transformation of the national economy. There is a global trend towards the use of the processes based on digital solutions. In addition, there are significant opportunities for the emergence of integration processes. Digital integration has an impact on international cooperation. The economic integration of countries becomes impossible without the digitalization of economic systems, legal frameworks, and technologies. The activities of supranational and national bodies of integration associations are adapting to the rapidly developing digital environment. Theoretical analysis. The main directions of legal support for integration processes of digitalization of the Eurasian Economic Union (the EAEU) space at the current stage is the creation of public administration mechanisms through the adoption of policies and programs at the national level. Future development of relations between the EAEU member states within the framework of legal integration on the path of digital transformation largely depends on consolidation and coordination decisions made by national governments in the field of information technologies introduced into the public administration system. This measure requires harmonization and unification of the fundamental legal documents of the member states of the Eurasian Union, which are responsible for the development of digital cooperation of the EAEU member countries in the long term. In addition, a special role is given to the convergence of mechanisms for the organization and functioning of national digital platforms and services towards the creation of a unified information system of the cross-border space of the EAEU. When identifying the fundamental problems of forming a common digital space within the Eurasian Union, the author studied foreign experience of building common digital platforms within the framework of integration associations using the example of the European Union. Results. The improvement of the current legal regulation of digital integration in the EAEU is due to the eff orts of the member states to implement close coordination and make agreed decisions to promote the common digital agenda of the Eurasian Economic Union.
