AEAT blocks registration in mortgage auction: what banks and funds must do in 2026

Key data

If your entity executes mortgages or acquires portfolios of awarded assets, this resolution changes the rules of the game. The General Directorate of Legal Security and Public Faith confirms, in its resolution of May 27, 2026, that a preventive annotation of prohibition to dispose ordered by the AEAT blocks the registration of the awarded property, even if the mortgage that motivated the execution predates that prohibition.

Until now, many financial entities assumed that the registration priority of the mortgage guaranteed clean registration of the awarded property. This doctrine demonstrates that this assumption is incorrect when there is a subsequent administrative charge.

What does this regulation establish?

The resolution arises from an appeal against the negative qualification by the property registrar of Madrid no. 37, which suspended the registration of an award decree and order for cancellation of charges. The reason: there was a preventive annotation of prohibition to dispose ordered by the Special Delegation of Madrid of the AEAT, registered after the executed mortgage.

The General Directorate confirms the negative qualification and establishes the following principles:

• Administrative public order prevails over mortgage registration priority. It is not enough that the executed charge (the mortgage) be prior to the prohibition to dispose.
• The AEAT must rule expressly. The administrative authority that agreed to the measure must indicate whether it authorizes registration and whether the prohibition subsists or is cancelled.
• Additional documentary requirements in the award decree: must include the declaration on potentially contaminating soil activities and the statement on freedom from leases. Both may be provided in a separate application with authorized signature.

Economic and operational impact

The impact is not theoretical. Any financial entity or fund that has awarded properties with administrative charges subsequent to the mortgage may find that those assets are not properly registered in their name, which directly affects:

• The accounting valuation of the asset (a property not registered cannot be counted as an effective real guarantee).
• The possibility of selling or refinancing the awarded asset.
• The timelines for resolution of execution proceedings, which are extended while the express ruling of the AEAT is obtained.
• The legal and registration costs associated with remedying proceedings already initiated.

Operationally, the mortgage execution process on properties with AEAT prohibition to dispose requires an additional mandatory step: obtaining the express ruling of the competent AEAT Delegation before presenting the award decree to the Registry.

Who does it affect?

• Mortgage creditor entities (banks, savings banks, credit cooperatives) that execute mortgages on properties with preventive annotations of prohibition to dispose by the AEAT.
• Investment funds and servicers that manage or acquire portfolios of assets awarded in mortgage auction.
• Individual or corporate award recipients who have obtained an award decree in auction and intend to register the property.
• Property registrars, who must apply this criterion in their qualifications.
• Lawyers and court officers who process mortgage executions with subsequent administrative charges.

Practical example

A bank executes a mortgage on a property in Madrid. The mortgage was registered in 2019. In 2023, the Special Delegation of Madrid of the AEAT annotates a prohibition to dispose on that same property due to a tax debt of the owner. In 2025, the bank obtains the award decree after the auction.

When the bank presents the decree to the Property Registry of Madrid no. 37, the registrar suspends the registration: the AEAT prohibition to dispose, although subsequent to the mortgage, closes the registry. The bank cannot register the property in its name until the Special Delegation of Madrid of the AEAT issues an express ruling indicating whether it authorizes registration and whether the prohibition is cancelled or subsists.

While that ruling is not obtained, the asset cannot be sold, refinanced or counted as a registered real guarantee. The bank must initiate a specific procedure with the AEAT to unblock the situation.

What should companies do now?

1. Audit the portfolio of awarded properties pending registration. Identify which assets have preventive annotations of prohibition to dispose by the AEAT subsequent to the executed mortgage.
2. Verify the registration status before initiating execution. Request an updated simple note from the Property Registry to detect administrative charges before presenting the award decree.
3. Initiate the procedure with the AEAT to obtain the express ruling. Contact the competent AEAT Delegation so it rules on whether it authorizes registration and whether the prohibition subsists or is cancelled.
4. Review award decrees in progress. Check that they include the declaration on potentially contaminating soil activities and the statement on freedom from leases, or prepare a separate application with authorized signature.
5. Update internal mortgage execution protocols. Incorporate the step of verifying administrative charges and obtaining the AEAT ruling as a prerequisite to registration submission.
6. Consult with specialized legal counsel on proceedings already initiated where this type of charge may exist, to assess the impact on timelines and accounting valuation of assets.
