This article covers the organization and implementation of the information and analytical work by the prosecuting authorities within public prosecutor's supervision over the compliance with the law on disposal of land. The concept of public prosecutor's supervision is developed in general, but also in relation to the sphere of legal relations relating to land. For the first time in public prosecutor's supervision knowledge the article highlights five main groups of sources for the Prosecutor General to obtain information on violations of the law in the disposal of land, the use of which will increase the efficiency of supervisory activities. The author proposes to understand 'proper information and analytical work' as the collection, accounting, accumulation and analysis of the information on the state of the law in this sphere of relations in order to define the priorities of supervision, measures to improve its effectiveness, formation plans, prepare and conduct inspections by the prosecutors and the application of appropriate measures in response to violations.
