In recent years, the population in Iran has been increasing. This growth in the population of large cities multiplies the demand for dwellings. The increase in demand, in turn, has led to the creation of high-rise buildings and numerous complex registration maps in these buildings. The current method for registering and storing various legal boundaries in Iran is based on two-dimensional maps. This method has its limitations for visualizing different registration boundaries that define legal spaces. For this reason, a new method to register the ownership of buildings accurately and efficiently is more than ever needed. With the advancement in the field of 3D modeling, especially Building Information Modeling, a lot of research is being done to record the three-dimensional legal boundaries using these models in different countries. In this article, for the first time, Building Information Modeling was used to record three-dimensional legal boundaries in the Iranian jurisdiction. To do this, first different types of registration boundaries in Iran were identified according to the regulations of the Real Estate Registration Organization of Iran and the building subdivision instructions in Iran. Then, to record these boundaries, Industry Foundation Classes (IFC) was developed and implemented on a prototype, which is a building in Tehran. In the evaluation stage, the registration boundaries in the two proposed methods and the current method were compared using a questionnaire. The results of this evaluation in different criteria showed the high capability of the proposed method in registering and visualization legal boundaries approved by the Real Estate Registration Organization so that more than 80% of the elite community participating in the questionnaire considered this method more appropriate than the current method.
