Abstract
Legal regulation of entrepreneurial activity is carried out by a complex of legislative acts representing various branches of law. The main source of legal right here is the law, but business activities are also regulated through judicial practice. Its increasing importance as a regulator of public relations is examined. The tendencies of the development of modern market economy are traced, forming the new contents of many traditional institutions, which is sometimes quite unexpected not only for the participants of these relations, but also for the legislator who cannot always orient in the dynamics of the property turnover relations. It is noted that the judicial authority through its activity approves the legal order regime in our yet only emerging market economy.
