The method used in this research is descriptive-analytical, with the main approach being normative juridical. Electronic registration, carried out by the Land Office based on Government Regulation Number 18 of 2021, has been very helpful in registering land rights or updating data in the transfer of ownership. However, there are still many obstacles or problems due to human error, such as a lack of Human Resources who are not ready and servers that often experience trouble or difficulties, thus complicating and hindering the land registration process.
