This study aims to analyze the adequacy of the applicable legal framework in ensuring the legal certainty of electronic land certificates and to formulate a model for reconstructing legal certainty to strengthen the validity and reliability of digital land registration. This research is a normative legal research with a statutory and conceptual approach, using primary and secondary legal materials that are analyzed qualitatively through legal interpretation methods and juridical argumentation. The results of the study show that the existing legal framework has provided a normative basis for electronic certificates, but it has not fully guaranteed comprehensive legal certainty due to the potential for regulatory disharmonization, the regulation of evidentiary strength has not been optimal, and the security standards and state accountability mechanisms have not been rigorous. The reconstruction of legal certainty is needed through the harmonization of regulations, strengthening the legitimacy of proving electronic certificates, integrating cybersecurity standards in the land system, and establishing a transparent digital correction and audit mechanism. With a theoretical approach to legal protection, this reconstruction is expected to be able to realize a valid, reliable, accountable, digital land registration system that guarantees the protection of land rights in a sustainable manner within the framework of the Indonesian legal state.
