The authors analyze the standards and regulations for scientific (engineering) expertise in several foreign countries to identify common approaches and characteristics. The general scientific, legalistic and structured system research methods are applied. The legal acts of China, USA, Great Britain, Germany, India and Japan are selected from the ranking as the leaders in the number of articles in periodicals indexed in the global databases, and number of patent applications and patents for inventions granted by the countries’ patent offices. Among the common features of the expertise regulations in these countries are: lack of special procedures for scientific expertise, freedom for private (nongovernmental) entities to establish expertise rules when the expertise subjects are not funded through the state budget. The authors divide the countries under the study in respect of the mandatory expertise state regulation and level of regulation into two groups. The experience of the latter may bу addressed when developing the national federal law in the sphere of scientific (engineering) expertise.
