The enforcement of Mortgage Rights in Indonesia is essentially intended to provide legal certainty for creditors in obtaining repayment of receivables when debtors default. However, in practice, the enforcement of Mortgage Rights over disputed objects continues to raise legal issues, particularly due to the dualism between the mechanisms of parate execution and executorial beslag. This study aims to analyze the legal regulation of parate execution and executorial beslag, examine the dualism of their implementation in judicial practice, and assess the legal certainty of Mortgage Rights enforcement over disputed objects. This research employs a normative juridical method with statutory, conceptual, and case approaches. The legal materials used consist of primary, secondary, and tertiary legal materials, which are analyzed through descriptive qualitative analysis. The results of the study indicate that Law Number 4 of 1996 concerning Mortgage Rights has provided a legal basis for creditors to carry out enforcement through parate execution and executorial title. However, in judicial practice, the enforcement of disputed objects often still involves the court through the mechanism of executorial beslag. This condition creates inconsistency in the application of law and affects legal certainty for creditors, debtors, and third parties. Therefore, regulatory harmonization and consistency in judicial practice are needed so that the enforcement of Mortgage Rights can be carried out effectively, fairly, and with balanced legal protection for all parties.
