Public Registry Digitalizes Registration Certificates

General Resolution 5/2026 of the Public Registry of the City of Buenos Aires (IGJ), published in the Official Gazette on June 2, 2026, establishes a new procedure for generating and delivering digital registration certificates. The regime will apply gradually to the entities and registrable acts included in the IGJ’s Implementation Schedule. Proceedings not yet included will remain subject to the procedure established in IGJ General Resolution 15/2024.

Under the new procedure, once registration has been completed, the IGJ will generate a digital certificate that includes the registered documents as embedded files. The certificate will be delivered to the authorized recipient through the agency-enabled digital platform, while the original instrument, whether public or private, will remain in the administrative file.

The Resolution specifically provides that the certificate must be digitally signed by the competent official. This distinction is relevant because Law 25506 distinguishes digital signatures from electronic signatures. A digital signature makes it possible to verify the signatory’s identity and detect any alteration made to the document after it was signed. It also benefits from presumptions of authorship and integrity. Therefore, unless proven otherwise, the signature is presumed to belong to the holder of the certificate used to verify it, and the document is presumed not to have been modified since it was signed.

These characteristics make it possible to attribute the certificate to the competent official and verify the integrity of its contents. According to the recitals of the Resolution, the certificate constitutes the registration act itself and has full legal effect as a digital instrument, following the terms of article 11 of Law 25506.

The new procedure also provides for the digital recording of certificates. In addition, once the implementation schedule includes acts requiring individual resolutions from the Inspector General, those resolutions will be issued electronically and digitally signed by the Inspector General. Where applicable, the instruments submitted for registration will be embedded in those resolutions, which will in turn be embedded in the digitally signed certificate.
