<![CDATA[This research is motivated by the suboptimal authority of the Regional Supervisory Council (Regional Supervisory Council/MPD) in enforcing the law against violations of the notarial office, which affects legal certainty and the professionalism of notaries. The legal framework governing notarial supervision is regulated under Law Number 2 of 2014 concerning the Amendment to Law Number 30 of 2004 on the Office of Notary and Regulation of the Ministry of Law and Human Rights Number 15 of 2020 concerning Procedures for Examination by the Notary Supervisory Council. In practice, the MPD still faces limitations in authority, institutional coordination, and supervisory effectiveness. This study aims to analyze the legal framework, implementation, obstacles, and reconstruction of the MPD's authority in law enforcement against violations of the notarial office in Batam City.This research employs the theories of the rule of law, authority, legal certainty, and law enforcement. It uses an empirical legal research method with statutory, conceptual, and sociological approaches. Data were collected through library research and interviews and were analyzed qualitatively. The findings indicate that the existing legal framework governing the MPD's authority has not fully supported effective law enforcement. Although supervision in Batam City has been implemented, it remains constrained by limited authority, weak institutional coordination, and ineffective follow-up on examination results. The reconstruction of the MPD's authority is therefore necessary through regulatory reform, stronger institutional coordination, capacity building for supervisors, and the utilization of technology in the supervisory system. The study concludes that reconstructing the MPD's authority is essential to strengthen law enforcement against violations of the notarial office, thus enhancing legal certainty and notarial professionalism. It is recommended that the government improve the existing regulatory framework and strengthen institutional and supervisory mechanisms to enhance the effectiveness of the MPD's functions.]]>
