The article deals with the examination of a legally protected interest as a legal means of securing actual exercise of civil legal capacity by the concerned participants. Assuming that not all legal possibilities amount to subjective legal rights (as opposed to law), the author considers legally protected interests within the scope of civil law that are not mediated by such subjective rights. A lot of civil law (sectoral) interests described in the article include legal interests, i.e. legal forms for those interests that are intended to change the legal status of an individual. As a part of the legal interest and legal means in which it is transformed, the author justifies the existence of a specific legal phenomenon, namely: A protected legal possibility to reasonably expect profitable legal consequences, or right expectation. This legal possibility takes the legal interest of a person as a member of a developing public situation which is fixed by the legal construction of an uncompleted actual composition. The author points out that the establishment of right expectation by civil law constitutes a rewarding sanction for the fair legal initiative of the person concerned. The author provides arguments in favor of integrating all legal possibilities into the sectoral legal regime as a repeating feature. Such a universal legal regime referred to as a regime of the right to expect includes subjective civil rights, legal interests and other legal means aimed at securing an intermediate legal possibility to a person who possesses transforming right to expect. Based on the survey, it is proposed that the existing civil law be amended so that the right to expect will be reflected in the rules of law. The article is intended for anyone interested in the development of fundamentals of civil law.
