Introduction. Today, universities face the task of establishing cooperation with business, including in the field of creating language courses for advanced training within the framework of the transfer of educational technologies. The author presents a unique experience in the development of language training courses “English for lawyers” (Financial University under the Government of the Russian Federation, 2023). Theoretical analysis. Conducting the comparative analysis of the problem allowed the author to conclude that the appeal to the CLIL-approach in ESP teaching through the tools of online pedagogy is justified. The client-oriented educational track constituted the uniqueness of this course. Empirical analysis. Consideration of the problem of using the CLIL-approach allowed us to identify the effectiveness of the selected methods: communicative, case study, inverted classroom, development of critical thinking, etc. in the field of ESP teaching. Conclusion. The use of the CLILapproach in the ESP training of practicing lawyers is effective and justified in terms of language proficiency development. Such courses allow one to see trends in the labor market and make appropriate adjustments to the educational tracks of universities.
