The implementation of the Job Creation Law has brought significant changes to the regulation of foreign investment in Indonesia, particularly through the establishment of a minimum capital requirement for a Foreign Investment Limited Liability Company (PT PMA) of IDR 10 billion. This study aims to examine the formal minimum capital requirements for PT PMA in notarial deeds under the Job Creation Law using normative juridical methods with statutory, conceptual, and case study approaches, and referring to the theory of legal certainty, responsibility, and legal protection. The analysis includes the evolution of PT minimum capital regulations, capital classification within the company's legal structure, the phenomenon of fictitious PT PMAs such as the PT BKG case, and the status and limitations of notary responsibilities. The results of the study indicate that although the minimum capital requirement for PT PMAs has been explicitly stipulated in Government Regulation No. 5 of 2021 and Regulation of the Head of the Investment Coordinating Board (BKPM) No. 4 of 2021, there are legal loopholes in the form of unclear capital deposit periods, weak verification and oversight mechanisms, and the prevalence of nominee practices and fictitious PT PMAs that reduce the effectiveness of the policy. The notary's position as a public official plays a strategic role in drafting deeds of establishment, verifying documents, and providing legal counseling, but has limited authority in verifying material truth. The study concluded that regulatory improvements are needed through establishing clear capital deposit periods, strengthening verification and oversight mechanisms, and harmonizing regulations between institutions to ensure the effective implementation of minimum capital requirements for foreign-owned companies (PT PMA) in accordance with the principle of economic sovereignty.
