Law Number 2 of 2014 Concerning the Amendment to Law Number 30 of 2004 Concerning the Position of Notary which regulates the Position of Notary, specifically regulates the rights, obligations and prohibitions that must be obeyed by notaries in carrying out their positions. This research focuses on the main objectives, namely first analyzing the arrangements related to violations of the notary office area based on the Notary Office Law in Indonesia, and second analyzing the application of sanctions against notaries who violate the notary office area, with reference to the decision of the Notary Regional Supervisory Council Number: 2/PTS/Mj.PWN.Prov.DKI Jakarta/II/2023. This research uses an empirical normative approach, utilizing secondary sources and data consisting of primary legal materials such as UUJN, complemented by secondary legal materials from relevant literature, and also tertiary legal materials such as interviews. The results of this study explain that although the UUJN has regulated the Notary Office in Indonesia, the fact is that there are still notaries who violate the notary office area. This study concludes that the implementation of UUJN in tackling violations of the notary's territory has shown positive results. Notaries who commit violations of the territory of the office are due to a lack of awareness or even forget the prohibitions contained in the UUJN or the notary code of ethics, therefore the Government of Indonesia (Pemerinta) must ensure that the notary's territory is not violated.
