Digital transformation in notarial supervision represents a strategic initiative to enhance the effectiveness and efficiency of monitoring the performance of notarial duties, particularly in preventing violations of notarial territorial jurisdiction. One such innovation is the development of an Online Reporting System that enables proactive, technology-based supervision of territorial jurisdiction violations. This system is designed to facilitate reporting and early detection of violations, as well as to accelerate the response of the Notarial Supervisory Council. Through the online reporting system, stakeholders, including notaries and the public, are able to report indications of violations in real time, which are subsequently verified by the supervisory authority. The utilization of the resulting data allows for more structured, transparent, and measurable supervision in preventing and addressing violations. This digital transformation also supports improvements in governance and accountability within the notarial institution in Indonesia, enhances public trust, and reduces the potential for conflicts or disputes related to notarial territorial jurisdiction. The results of the analysis indicate that the implementation of the online reporting system is effective in reducing the number of territorial jurisdiction violations and increasing compliance with applicable regulations.
