Mexico and Paraguay implement digital property registration reforms

Mexico has approved the General Law for the Strengthening and Harmonization of Cadastral and Registry systems. The reform introduces the Clave Única Catastral (CUC), a unique identification key for every property designed to link municipal cadastral data with Public Property Registries. This digital integration aims to reduce deed errors, real estate fraud, and property disputes by eliminating discrepancies between physical land measurements and ownership records. The initiative also intends to use satellite imagery and georeferenced maps to detect undeclared constructions, potentially increasing municipal tax revenue. Digital processes will be managed via cloud platforms under the Agency for Digital Transformation and Telecommunications.

In Paraguay, the government has introduced the Digital Real Estate Cadastral Registry Certificate (CCRID) to unify cadastral, registry, and survey information into a single digital process. While promoted by President Santiago Peña as a technological milestone, the initiative has faced criticism from the Movimiento Nacional de Opiniones Tetagua Sapucai. Critics argue that digitizing administrative processes without first auditing and correcting existing errors in the underlying graphic and cartographic data risks legitimizing systemic corruption and property title overlaps, thereby increasing legal insecurity for owners.
