The place and role of the legal profession among other state authorities has been established.The authors come to the conclusion that the institution of advocacy in the mechanism of protection of the rights and freedoms of a person and citizen is one of the means for self-limitation of state power through the creation and active functioning of an independent human rights institution, which is an active actor in the process of implementing the main constitutional functionof the state - the implementation and protection of rights and freedoms person and citizen. The constitutional and legal status of the bar allows it to actively ensure the rights of not only every person, but also of the entire civil society, to effectively implement the human rights function of the state by ensuring proper interaction in the activities of state authorities and civil society.
 The main features of advocacy that reveal its essence in the mechanism of providing legal aid are: 1) advocacy acts as a separate human rights institution; 2) the bar actively interacts with state authorities and institutions of civil society as anequal partner in the mechanism of protection of human and citizen rights and freedoms; 3)as part of their professional duty to protect the rights and interests of their clients, lawyers play a significant role in the fair administration of justice.
