The article examines the features of the legal regulation of the legal profession and the advocate as the main subject of the provision of qualified legal assistance. The author comes to the conclusion that now there is a need for a legal definition of the concepts of «legal aid» in general, and «qualified legal aid» in particular. This must be done within the framework of federal law, which could legally manifest semantically those concepts that currently exist only at the doctrinal level. For the full development of the system of providing qualified legal assistance with the aim of the fullest realization of constitutional rights, it is necessary to strengthen state mechanisms for the protection of rights and freedoms, and to reform non-state mechanisms, in particular, the legal profession.
