This study aims to analyze and identift the validity of the Notary deed that was not read out by the Notary before the applicants and, to analyze and identify the role of the Notary Supervisory Board in terms of enforcing UUJN regarding the behavior of a Notary who does not read the Notarial deed that they have made. This is a qualitative normative legal research as it examines legal norms related to the validity of notarial deeds which were not read out by the notary before the applicants and witnesses at the time of signing the minutes of the deed. The results of the study concluded that the Notary is obliged to guarantee the certainty of the day, date, month, year, and facing time listed or mentioned at the beginning of the Notarial deed, as proof that the parties face and sign the deed and all procedures for making the deed have been carried out according to the applicable legal regulations in UUJN. In the case of the notarial deed not being read to the applicants and witnesses due to the notary's negligence is certainly in contrary to the UUJN provisions, which undoubtedly will have legal implications for both the deed and the notary concerned. The reading of the deed that is not carried out by a Notary will result in a decrease in the value of proving an authentic deed to become a private deed as stated in Article 16 paragraph (9) UUJN.
