Mexico new Cadastral Law unique cadastral key for homes, Digi Mart USA News: Recently, a topic of interest has emerged among Mexicans regarding the new General Law for the Strengthening and Harmonization of Cadastral and Registry Matters across the country. The law will bring changes to real estate management through a unified, digitalized national system, prompting people to ask whether their properties will receive a kind of Unique Population Registry Code (CURP).
The new law seeks to modernize, update, unify and make interoperable the databases of local cadastres and the Public Property Registries. It aims to establish the basis and coordination mechanisms among the federation, states and municipalities.
Authorities hope to eliminate discrepancies in criteria among different municipalities across Mexico, reduce bureaucracy in real estate procedures and provide greater legal certainty to property holdings.
It has been confirmed that a Clave Única Catastral, a unique code identifying each property in the country, will be created, similar in concept to the CURP used for citizen identification. Authorities will assign the new key to each registered property to better establish its location and physical characteristics.
It will also be linked to the Folio Real of the Public Property Registry, which contains data on legal rights related to the property or home.
The goal is to bring together the physical and legal data of all properties in the country in a single record, making them easier for authorities to identify and consult. The new key does not replace home deeds, and owning the key does not make a person the legal owner of a property.
The new system is intended to speed up these procedures so that the entire country follows similar rules. Planned measures include online tools for consulting and managing property-related procedures, map review and electronic payments.
Citizens will be able to identify themselves digitally through Llave MX. Requirements, forms and procedures will be standardized for all states and municipalities.
Systems will also be able to exchange information to identify discrepancies between the physical data of land or properties and the documents on record.
The system will be implemented nationwide by the Secretaría de Desarrollo Agrario, Territorial y Urbano (Sedatu) and the Agencia de Transformación Digital y Telecomunicaciones. Guidelines related to the Clave Única Catastral must be issued within 30 business days, along with the rollout of digital platforms.
All states and municipalities have until December 31 to adopt the new provisions, which will begin operating on January 1, 2027.
