The purpose of the article is to analyze the constitutional and sectoral aspects of the realization of the right to free legal aid, to determine the optimal subject of administration of the system of free secondary legal aid in Ukraine.Research methods. The methodological basis of this work is a complex of general scientific and special methods and techniques of scientific knowledge, in particular, dialectical, system-structural, formal-logical, statistical method, as well as methods of modeling, analysis and synthesis, etc.Results and conclusions. According to art. 59 of the Constitution of Ukraine, the Law of Ukraine «On free legal aid», procedural codes and by-laws, an extensive system of free legal aid has been created in Ukraine, including the provision of free primary and secondary legal aid.Despite the harsh conditions of a full-scale war, the free legal aid system has demonstrated institutional stability and an intention to develop and strengthen its human resources. The advocate’s corpus is an advanced vanguard and the basis of the FLA system, which is able to solve difficult professional and ethical issues that arose in connection with the russian military invasion. The realization of the management (administration) function of the FSLA system should be carried out by the Coordination center for legal aid provision. The transfer of this function to the bodies of the Ukrainian national bar association is not justified and carries the risks of reducing the clarity of the distribution of assignments for the provision of FSLA between advocates and payment for their services from the state budget.Many ukrainian advocates have changed ethical approaches to protect those suspected of committing crimes related to facilitating russian military aggression. The main reasons were patriotic beliefs, risks of human condemnation, identification of advocate and client, reputational and moral factors.To increase trust and transparency in the work of the FSLA system, it is advisable to stage the introduction of automated distribution of assignments among advocates based on certain criteria.
