What Is Ley Federal de Protección de Datos Personales en Posesión de los Particulares (new, 20 March 2025)?

The current Orden Jurídico text is marked TEXTO VIGENTE and identifies the new Federal Law on Protection of Personal Data Held by Private Parties as published 20 March 2025. The current Chamber of Deputies PDF identifies the same text and a 14 November 2025 last reform; the official decree confirms Article 4 was amended to reference the Código Nacional de Procedimientos Civiles y Familiares and the Ley Federal de Procedimiento Administrativo as supplemental procedural law. The current text does not support an exception-free or consent-free scope statement: Article 1 contains credit-information and qualifying personal/household exclusions, while Articles 7 and 9 establish consent subject to listed exceptions. Articles 21 through 26 provide access, rectification, cancellation, and opposition rights with statutory limitations, not a universal erasure guarantee. Article 31 states a maximum 20-business-day determination period and, if the request is procedent, 15 business days to make it effective, with one equal justified extension available — statutory ARCO process periods, not a provider SLA, deletion guarantee, or favorable-outcome promise. The current law assigns the federal private-party protection procedure to the Secretaría Anticorrupción y Buen Gobierno, with 2025 transition materials addressing former INAI functions and proceedings. A direct fetch of the Secretariat's 21 March transition release returned an access error during the 7 September 2026 review, so it is treated only as transition context alongside the controlling law and decree.

Notable features

Mexico's 2025 law is a genuinely new statute, not merely an amendment to the older LFPDPPP, and it arrived alongside a broader institutional transition: former INAI (the previous transparency and data-protection authority) functions moved to the Secretaría Anticorrupción y Buen Gobierno. Any current description must reflect both the new statutory text and the new authority.

Enforcement & penalties

Regulator: Secretaría Anticorrupción y Buen Gobierno (successor to former INAI private-sector functions)

Penalties: Not independently confirmed from the current text in the 9 October 2026 review; a future update should verify the current administrative sanctions schedule directly from the new law before publication.

Private right of action: No broker-specific endpoint, complete operational private-sector complaint form or portal, or universal public-record deletion rule has been verified. The federal private-party protection procedure is currently assigned to the Secretaría Anticorrupción y Buen Gobierno following the 2025 transition of former INAI functions.

Relevance to data brokers

No broker-specific endpoint, complete operational private-sector complaint form or portal, or universal public-record deletion rule has been verified. Mexico remains discovered-only for jurisdiction-specific broker, public-record, route, and outcome claims pending further review.
