The paper analyses the issue of registering buildings in the land register, considering the complexity of situations arising from their construction without full compliance with the authorization framework or with deviations from the approved documentation. It highlights the main particularities of the registration process, influenced by the time of construction and the degree of conformity with the legislation in force. The study addresses both the legal dimension, by presenting the relevant regulatory framework and the solutions provided by current legislation, as well as the technical dimension, through the use of modern topographic surveying and photogrammetric methods. It also highlights that for buildings erected without a construction permit, but for which the sanctioning term has expired, legalization may be achieved on the basis of a technical expertise. A practical case study illustrates how these instruments can substantiate the required documentation, ensuring both the accuracy and the reliability of the data. The integration of GIS provides a unified framework for recording buildings, by correlating cadastral and legal data with the actual field situation. Orthophotoplans obtained from UAV flights can be overlaid with information from the electronic eTerra system, which manages land registers and cadastral plans, thus facilitating the identification of buildings without legal documentation. Such a system would support both institutions and citizens, in a manner similar to systematic registration processes, although its implementation requires significant financial and logistical resources. The conclusions emphasize the importance of complying with legal procedures and using modern geodetic technologies to integrate buildings into the legal circuit, thereby contributing to the strengthening of real estate security and to a more efficient management of the built heritage.
