A notary, as a public official, has the authority to create authentic deeds required by society due to the special status of these deeds, which are recognized as strong and valid evidence under the law. This internship report states that Notary Nany Angkasa, SH., Sp. Notariat plays a vital role in ensuring the validity and certainty of the authentic deeds she creates, including the establishment deed of a limited liability company. In carrying out her duties and responsibilities, a notary must adhere to the Law of the Republic of Indonesia Article No. 2 of 2014, which amends Law Article No. 30 of 2004 concerning the Notary Office. Meanwhile, the procedures for submitting applications and granting business entity status recognition are regulated by the Law Article No. 40 of 2007. The role of a notary, as outlined in the law governing the Notary Office, is to draft deeds. However, in practice, society often lacks sufficient knowledge about the licensing process, so notaries also assist in providing other related services. This internship report explains that authentic deeds created by notaries provide stronger legal protection for the parties involved, but they also face various issues related to the notary's responsibility, the potential for misuse, and technical challenges in carrying out the notary's duties. This research is expected to contribute to a better understanding of the notary's role in the Indonesian legal system, as well as to provide recommendations for improving the implementation of notarial duties to support legal certainty.
