AEAT blocks mortgage executions: what adjudicatees must do in 2026

Key data

Winning a collection auction does not guarantee you can register the property in your name. This is confirmed by the Resolution of April 30, 2026 from the General Directorate of Legal Security and Public Faith (DGSJFP), published in the BOE on August 8, 2026. The specific case: the company Gasparito SL attempted to register a mandate for cancellation of charges issued by the General Treasury of Social Security, but the Property Registry of Cádiz no. 3 suspended the registration because the AEAT had noted a prohibition of disposal on the same property, after the executed lien.

The DGSJFP dismisses Gasparito SL's appeal and maintains its doctrine: prohibitions of disposal of administrative origin have a component of public order that generates registry closure, even when the execution that motivates the registration is based on an entry prior to the prohibition.

What does this regulation establish?

The resolution clearly establishes the DGSJFP's position on the conflict between two registry figures:

• Prior administrative execution: the TGSS executes a lien registered before the AEAT noted its prohibition of disposal.
• The AEAT's prohibition of disposal: noted after the executed lien, but before the request for registration of the mandate for cancellation of charges.

Gasparito SL's argument was that article 145 of the Mortgage Regulation only prevents subsequent dispositive acts by the registry owner themselves, not registrations derived from prior entries. Additionally, it argued that the DGSJFP departs from the doctrine of the Supreme Court.

The DGSJFP rejects both arguments and consolidates its doctrine: administrative prohibitions of disposal are not simple civil charges. Their component of public order grants them an effect of registry closure that operates even against earlier executions in time, as long as express administrative authorization is not obtained.

Economic and operational impact

The practical consequences for an awarded company are significant:

• Asset immobilization: while the AEAT authorization is not resolved, the property cannot be registered, transferred or mortgaged. Any financial or commercial operation on that property is paralyzed.
• Opportunity cost: the time spent on administrative processing before the AEAT is added to the time already invested in the collection procedure. Depending on the workload of the corresponding Regional Collection Department, the process can take months.
• Additional legal costs: the company will need specialized legal advice to manage the authorization request before the AEAT and, if necessary, to challenge a denial.
• Risk of loss of the property: if the AEAT does not lift the prohibition, the award may become without practical effect, with the consequent economic damage to the awardee.

This resolution does not introduce a new regulatory change, but rather consolidates and reinforces an existing doctrine of the DGSJFP. Its publication in the BOE on August 8, 2026 makes it a mandatory reference for registrars and legal advisors from that date forward.

Who does it affect?

• Companies awarded in collection procedures of the General Treasury of Social Security or other collection bodies, when there is a prohibition of disposal from the AEAT on the property.
• Individuals who have acquired properties in administrative auctions under the same circumstances.
• Legal advisors and administrative managers who process registrations derived from administrative executions.
• Property registrars, who must apply this doctrine in their qualifications.
• Financial and M&A departments of companies that acquire real estate assets from public auctions or bankruptcy proceedings with pending tax debts.

Practical example

The real case that originates this resolution perfectly illustrates the problem:

Gasparito SL participates in a collection procedure of the General Treasury of Social Security and is awarded a property in Cádiz. The TGSS issues the corresponding mandate for cancellation of charges so that Gasparito SL can register the property in its name in the Property Registry of Cádiz no. 3.

However, after the TGSS lien but before the mandate is presented to the Registry, the Regional Collection Department of Cádiz of the AEAT had noted a prohibition of disposal on that same property.

The registrar suspends the registration. Gasparito SL appeals to the DGSJFP arguing that the prohibition should not affect an execution based on a prior entry. The DGSJFP dismisses the appeal: the AEAT's prohibition of disposal generates registry closure regardless of the age of the executed lien. Gasparito SL must obtain express authorization from the AEAT before being able to register the property.

What should companies do now?

1. Before participating in any collection auction: check the Property Registry to see if there are any prohibition of disposal annotations on the property, especially from the AEAT. This check should be done immediately before the auction, not just at the beginning of the process.
2. If you are already an awardee and the Registry suspends the registration: identify the body that noted the prohibition (in this case, the corresponding Regional Collection Department of the AEAT) and formally request administrative authorization to register.
3. Document the complete file: keep all documentation of the collection procedure, the mandate for cancellation of charges and the Registry's suspension notice. It will be necessary for the request before the AEAT.
4. Assess the administrative litigation: if the AEAT denies authorization, analyze with your legal advisor the viability of challenging the resolution, taking into account that the DGSJFP maintains a doctrine contrary to the arguments of article 145 of the Mortgage Regulation.
5. Review ongoing operations: if you have other pending registrations, verify if there are any prohibition of disposal annotations and act preventively before the Registry issues a negative qualification note.
