The study reveals the content of the Biy court as a socio-political value of the Kazakh people. The article is devoted to the study of the Biy court as a fundamental institution of Kazakh customary law and its potential role in the modern legal system of Kazakhstan. The relevance of the research is emphasized due to the need to improve domestic legislation and the judicial system, as well as the desire to use the centuries-old traditions of our ancestors to improve the effectiveness of justice. The expediency of creating a specialized scientific research state institute for the comprehensive and comparative study of Kazakh law "Jargy" and justice biy is substantiated, and an example of foreign experience (Canada, Australia) in creating such centers to take into account local legal specifics is given. Such an appeal to the age-old traditions of our ancestors is largely determined by the need to radically improve the current domestic law and the judicial system of the country. It is noted that the foreign experience of the organization and operation of magistrates' courts deserves careful attention of the domestic legislator. It is advisable to introduce the Biy court into the unified judicial system of the country, as a court of first instance, in order to expand the availability of judicial protection for rural citizens and significantly reduce the burden on district court judges. In this regard, it is necessary to adopt appropriate additions and amendments to the Constitution of the Republic and to the Constitutional Law "On the Judicial System and the Status of Judges", as well as an independent Law "On Judicial Courts in the Republic of Kazakhstan".
