This article is devoted to the advantages and disadvantages of the model of advisory (deliberative) democracy. Its basic provisions are revealed, the contribution to its development of J. Besset, J. Habermas, J. Cohen, R. Dahl, J. Fishkin is characterized. It has been established that the model of advisory democracy offers tools for active participation of the population in the discussion of important political issues in the period between elections. When discussing problematic issues, the right to vote is given to all those who are influenced by the decisions of public authorities (the principle of equity participation). At the same time, the dialogue should be free, equal, reasoned and aimed at reaching consensus.
 The main problems of deliberative democracy are highlighted, including the difficulty of reaching a general consensus in a socially heterogeneous society, leveling important social differences in the process of compromise, unpreparedness of citizens for a rational dialogue, the presence of cultural barriers in implementing advisory procedures in non-Western countries. Forms and methods of informal participation of citizens in the discussion of political issues in the United States, as well as in Germany, Spain, Belgium, Iceland, Poland and other European countries are considered. Emphasis is placed on the fact that the use of advisory procedures in the world is characterized by a variety of deliberative tools and the breadth of its application: from solving problems of education and ecology, medicine and the local budget to the adoption of a new constitution.
 It is established that the concept of deliberative democracy takes into account both negative realities (alienation of political power from society, low level of public confidence in the political elite) and positive achievements of today (the idea of "good governance", information technology, ideological and legal pluralism). In view of this, it is concluded that the model of advisory democracy is a promising attempt to modernize democracy in the modern world, rethink the democratic principles of government, adapt the classical theory of democracy to modern needs and challenges.
