The topic of the diploma thesis is closely related to the cadastral procedure of boundary adjustment. Two decades ago, the Slovenian legislation in the field of land cadastre introduced a new cadastral process for individual rearrangement of cadastral boundaries, called boundary adjustment. The procedure of boundary adjustment is used for various purposes due to the weak legal provisions. Still, on the other hand, the instrument of boundary adjustment does not always allow us to find a solution due to legal restrictions. The purpose of the diploma thesis has been to analyse the selected boundary adjustment cases, as recorded in the official documentation of the land cadastre, aiming to understand better the cadastral boundaries’ readjustments needs in the practices and to identify the possible legal weakness of the current measure. The selected boundary adjustment cases have been analysed and presented in collaboration with a certified surveying engineer. It has been shown that boundary adjustment has become an important instrument of the individual cadastral boundary rearrangements. In the practice, it is used for various cadastral cases, which could not be solved only by boundary settlement and land subdivision or the process would be disproportionately more complex.
