The relevance of the topic is determined by the necessity in realizing current changes in legal science.The essence of the changes is explained by the fact that our perception of reality is based on differentscientific paradigms. The world is represented as a place full of contradictions and disorder, and weare looking for a framework that will fill it with sense. Many researchers are widely using concepts andmethods of synergetrics, which is usually referred to as the theory of chaos in American scientific literature.Synergetrics helps to study a certain aspect, connection of a legal phenomenon. Therefore, thisapproach can be applied not in any research, but only in those requiring studying certain aspects andfeatures of a phenomenon. The synergetic paradigm allows revealing such new characteristics of legalsystems as: openness, self-organization, nonlinearity in the development of social and legal phenomena.At the time when the harmonization of the Russian and international legal systems is a priority, thetransformations in the sphere of international relations are being taken into account. The knowledge oflegal entropy will give a chance not only to explain many features of self-organization, disorganizationand self-government of legal systems, but to develop the approaches, techniques allowing influencingthe choice of the alternative ways of their development. Laws of the chaos theory can help while studyingthe dynamics of the modern civilization processes. At the same time, the complexity of the environmentmeans a number of factors, influencing the work of various social organisms. This complexityalso includes variability of these factors. Nowadays, hardly any country does not depend on the globalinformational, financial, economic, technological systems. A similar situation influences economy, politicaldecisions and the system of legal regulation. At the same time there is an issue with the legitimacyof applying characteristics disorder, uncertainty, disorganization to the law, which, as a tool, provides thebalance in social relations, adding essential certainty. This question is quite legitimate since there is nocurrent solution in the modern legal science.
