Abstract: The object of this research is establishment of the principle of good faith at different historical periods in the context of formation of various approaches in the doctrine and practice of civil law. Due to the absence of unanimity of opinions regarding the formation of moral-ethical categories within the national civil law, this scientific field is considered problematic and interesting for examination. The subject of this research is the historical, ideological and practical prerequisites that influenced the formation of concept of the principle of good faith in the national civil law. The scientific novelty consists in the proposed by the author principle of good faith in the historical, doctrinal and practical aspects, which leads to suggestion of future course of development of the principle of good faith in the national civil law by means of improving the current civil legislation. The conclusion is drawn that at the present stage the principle of good faith, despite the universality and crosscutting nature, initially forethought by the concept of development of civil legislation, should be concretized in the various civil legal relations, taking into account their peculiarities and specifics. Such type of circumstantiation of the general provisions of law would increase the possibility for introduction of corresponding amendments into the principle of good faith on the level of social norms.
