<![CDATA[This study examines the responsibility of the state in cadastral mapping as a basis for strengthening civil rights over land in Indonesia. Cadastral mapping occupies a strategic position within the land law system, as it serves as the foundation for land registration and the issuance of land title certificates, which function as evidentiary instruments in civil legal relations. Inaccurate mapping has the potential to give rise to land disputes, weaken the evidentiary value of land certificates, and cause losses to rights holders, even when such errors originate from state administrative processes. This research employs a normative juridical method using statutory, conceptual, and relevant court decision approaches. The findings indicate that state responsibility in cadastral mapping encompasses the establishment of standardized technical norms, the implementation of accurate and integrated mapping, and the provision of correction mechanisms and legal accountability for mapping errors. The accuracy of cadastral mapping directly affects the evidentiary strength of civil land rights, legal certainty, and the protection of land rights holders. Therefore, the state must promote the adoption of high-precision cadastral mapping supported by regulatory reform, enhanced human resource competence, and the integration of national geospatial data, so that cadastral mapping can function optimally as an instrument for the protection of civil land rights and the equitable administration of land affairs]]>
