Legal certainty is crucial in implementing fiduciary guarantees, especially regarding registration and execution as regulated in Law No. 42/1999. However, Constitutional Court Decision No. 18/PUU-XVII/2019 requires proof of default and mutual agreement before execution, raising practical challenges. This study uses a normative juridical approach by analyzing laws, court rulings, and doctrinal perspectives to assess legal consistency and post-decision constraints. The decision enhances debtor protection but causes procedural ambiguity, weakens executorial power, and delays execution. Inconsistent regulatory implementation worsens legal uncertainty. To restore legal certainty, derivative regulations must be revised and institutional practices harmonized. A fair balance between creditor rights and debtor protection is essential to maintain fiduciary guarantees as an effective credit instrument.
