The rapid development of decentralization processes in Ukraine puts a number of tasks to the scientists, especially the search for ways to improve existing models of management activity in the territories, in administrative-territorial entities, etc. World experience proves that the dynamic development of territories and the country as a whole cannot be ensured on a sustainable level without the decentralization of public administration, without the capacity of local self-government. Ukrainian local self-government has long faced challenges that cannot remain without an appropriate response. It goes about economically-financial insolvency of the vast majority of communities, actual absence of money in the budgets of development and investments in an infrastructure, in particular communal. In addition, all these problems first of all base on an imperfect normatively-legal base. Indeed, in order to achieve high results at the local level, a perfect legal basis and taking into account of regional specifics is necessary. In this article, the principles of organizational and resource support of the modern development of territorial communities are theoretically grounded. Different approaches to the essence of development of the United territorial communities are analyzed and all their features are determined. Several obstacles that exist in the process of achieving the goals of CTC are investigated. Special attention is paid to creation of public information system, which would stipulate free plan of local authorities’ inspections and measures of control for its accomplishment. The fact that respective authorities and public institutions should be attracted to this process to conduct independent monitoring of inspections’ efficiency is emphasized. The problems of functioning of the regulatory and legal support of territorial communities are considered, namely, most of the normative-legal acts concerning their influence on the functioning of the combined territorial communities are analyzed. The ways of financial support for the development of regions are shown and suggestions and recommendations for improving of local self-government functioning are formulated due to the increase of the level of normative and legal support for the development of territorial communities.
