This article attempts to consider an alimony relationship in the context of the balance of interests. The paper highlights peculiarities of the balance of interests in family legal relations, primarily in the legal relations related to the principle of ensuring the interests of minors and disabled family members. It is concluded that the balance of interests should be understood as the family legal relation where the rights and obligations of the parties are proportionate and the rights and legitimate interests of minors and disabled family members are properly protected. The balance of interests in alimony legal relations is considered at three levels: Legislative, law enforcement and individual (the level of agreements between the subjects of family Law), - and at three stages of the alimony legal relation: formalization of alimony obligation, fulfillment of alimony obligation, and changes and termination of the obligation. At the stage of the alimony obligation formalization, in order to ensure the balance of interests it is necessary, first, to establish the appropriate subjects of alimony obligations and their scope. However, both parties can be involved in abuses; the weaker side of the legal relation may also abuse its right to alimony. Ensuring the balance of interests at the stage of fulfillment of alimony obligations is primarily aimed at maintaining a decent standard of living for all participants of alimony legal relations. When alimony obligations are modified or terminated, a situational method of the family relations regulation plays an important role, in particular, if the amount of alimony payable is changed. The RF Constitutional Court clarifications play a significant role in ensuring the balance of interests in alimony relations.
