Ways of the closure facultative obligations

Introduction: from 1 June 2015 entered into force amendments to the Civil Code of the Russian Federation (further - GK the Russian Federation), which for the first time in Russian history the facultative obligation were enshrined in the General Part of the law of obligations (articles 308.2, 320.1 of the Civil Code). However, this is not enough. Only a proper understanding of the legislative structure of the facultative obligation will effectively use a dedicated civil legal norms, and to avoid contradictory judicial practice. The purpose is to address relevant for the development of Russian civil law tasks in uncovering the mechanism of the facultative termination of obligations. Results: a number of fundamental questions on the facultative obligations have not received proper authorization in the civil law doctrine. Among these issues is the problem of determining the range of grounds for termination of the facultative obligations. Methods: the study used the following methods: general scientific dialectic, universal scientific methods (analysis and synthesis, induction and deduction, comparison, abstraction, formal-logical, systematic and structural), exclusively legal methods (comparative-legal method, a system of interpretation, legal method of modeling). Conclusions: when the facultative termination of an obligation by impossibility of performance is theoretically conceivable three possible situations, different legal consequences: 1) the debtor is unable to provide the basic design, as it has become impossible due to circumstances for which neither party is not responsible; 2) the debtor is unable to provide the basic design, as it has become impossible due to circumstances for which the lender is responsible; 3) the debtor is unable to provide the basic design, as it has become impossible due to circumstances for which the debtor is responsible.
