The advancement of information and communication technology brought significant changes to various aspects of life, including the legal activities. One of the no impacts is the emergence of the Cyber Notary concept, an electronic system for creating and drafting notarial deeds. This study aims to examine the Cyber Notary concept within the context of notarial law in Indonesia and to analyze its implications for the validity of authentic deeds. In this research, the author elaborates on and investigates the discrepancies between the existing regulations in the Notarial Law and the reality in the performance of notarial duties as well as the lack of regulations related to technological aspects in the creation of notarial authentic deeds. This study finds that the Cyber Notary concept holds immense potential for enhancing the efficiency and effectiveness of notarial services. However, there is still considerable constraint in implementation in Indonesia because of existing legal regulations. This leads to legal uncertainty and hesitation among notaries and society in adopting the concept. The uncertainty regarding the authority and responsibilities of notaries in carrying out their duties through Cyber Notary might cause various issues, such as legal disputes, misuse of technology, and violations of notarial ethics. Therefore, in-depth research is necessary to examine the authority and responsibilities of notaries regarding the deeds created using the Cyber Notary concept. This study also finds that Cyber Notary Activities have implications for the validity of authentic deeds. The validity of electronically created authetic deeds needs to be further examined by considering both legal and technological aspects. It is important to ensure that electronically created authentic deeds have the same legal force as conventionally created ones. Based on the findings of this research, it is concluded that the transformation of notarial services in the digital era through the implementation of Cyber Notary requires robust, clear, and comprehensive legal regulations. This is important to ensure legal certainty and protect the rights of all parties involved in the drafting of authentic deeds.
