The aim of this paper is to present the need for changes of geodetic-legal procedures for the cadastre and real estate management. This problem was analyzed both in theoretical and practical terms. In order to better present the analyzed technical and legal procedures, a study of several cases of surveying documentation was made. On their example the problems associated with the surveying services were shows and the formal and legal procedures, on the basis of which described surveying works were done were verified. The problem presented is current and valid not only for the comfort of the surveyor's work, but also from the point of view of the structure and modernization of the real estate cadastre, constituting the backbone of the real estate management. The article emphasized the need to unify the databases of state registers and the digitization of the National Geodetic and Cartographic Resources (PZDGiK). Research has shown that despite the continuous changes of legislation, there are still many shortcomings and gaps, which often complicate the surveying works. The surveyor must analyze and verify all materials he uses, including those obtained from the Centre of Geodetic and Cartographic Documentation (ODGiK). The quality of the geodetic and cartographic elaboration depends largely on the work of the Centre of Geodetic and Cartographic Documentation. The need of modernization of the Land and Buildings Registry, which acts as a cadastre in Poland, has been demonstrated. Furthermore, the unification of data used as reference systems both for plane coordinates and elevation has been proposed.
