Records of land and buildings, in accordance with the regulations that remain in force within Poland, act as a real estate cadastre. As a public register, they must fulfil certain specific functions and tasks expected of them. The aim of the present work is to analyse land records data, as illustrated with selected examples, as well as to assess and verify the suitability of these materials in the scope of the functions performed by the real estate cadastre, and in the context of possible legislative changes. Literature studies and the analysis of sample cadastral surveys make it possible to draw conclusions regarding the proposed changes.
