Some problems of correlation of the categories "contract modification" and "contract termination" with related categories of civil law

The subject of this study is legal relations related to some features of the amendment and termination of the contract from related categories of civil law. The analysis of legislation, scientific materials and law enforcement practice allowed the author to formulate questions related to the qualification of such legal phenomena as "contract modification" and "contract termination". The researcher pays special attention to the possibility of improper interpretation of a legal fact by individuals and legal entities within the framework of contractual legal relations instead of "modification" and "termination of the contract". To the categories, the nature of which may be similar to the legal nature of the amendment and termination of the contract, the author refers to such phenomena as the conclusion of an additional agreement, the termination of contractual relations due to the expiration and invalidity of the contract. In the course of the research, the author used universal dialectical, logical, formal-legal, hermeneutic research methods. The relevance of the chosen topic lies in the modernization and development of the institution of modification and termination of civil contracts due to the dynamics of changes in economic and social aspects and interests of participants in legal relations. The legal aspects of the problems of the correlation of the categories "contract modification" and "contract termination" are considered in the works of such researchers as M.I. Braginsky, V.V. Vitryansky, I.V. Ginzburg and others. Based on the analysis of Russian legislation and the practice of implementing the categories of "modification" and "termination" of the contract, the author concludes that a more detailed and in-depth study of the terms of contractual relations is prioritized for their further proper qualification by both the parties to contractual relations and judicial authorities in the direct application of substantive law. The conclusions formulated based on the results of the work carried out can be used for further scientific research in the field of civil law and form the basis of future regulatory legal acts.
