| Category | Real Estate — Registry cancellation of mortgages |

| Key rule discussed | Art. 1,280.5 of the Civil Code (formalities of power of attorney) |
If you have a paid-off mortgage or manage registry cancellations, this resolution directly interests you. When a bank like Banco Santander grants the debtor themselves an irrevocable advance power of attorney so they can cancel the mortgage by themselves before a notary, the property registrar cannot require additional requirements on that power of attorney if the notary has already issued their judgment of sufficiency. This is established by the DGSJFP Resolution of February 18, 2026, published in the BOE on June 11, 2026.
The conflict arose when the property registrar of Madrid no. 3 refused to register a mortgage cancellation deed from Banco Santander in which the debtor acted with that irrevocable advance power of attorney. The registrar required proof of the signatory's powers of the zero balance certificate and their notarial legitimation. The notary appealed arguing that their judgment of sufficiency is binding and not reviewable by the registrar.
What does this regulation establish?
The resolution addresses two technical issues with very relevant practical consequences:
- Binding nature of the notarial judgment of sufficiency: When a notary issues their judgment of sufficiency on a power of attorney—in this case, the irrevocable advance power of attorney granted by the bank to the debtor—the property registrar cannot question it or require additional documentation to prove representative powers. This principle was already consolidated in registry doctrine, and this resolution reaffirms it in the specific context of advance powers for mortgage cancellation.
- Formalities of the zero balance certificate: It is discussed whether the zero balance certificate—a document that proves that the mortgage debt is paid and acts as a complementary requirement of the power of attorney—must comply with the formalities required by art. 1,280.5 of the Civil Code (which requires a public deed for certain powers of attorney). The resolution clarifies the scope of these formalities in this specific context.
| Element of the conflict | Position of the registrar | Position of the notary / DGSJFP |
|---|---|---|
| Notarial judgment of sufficiency on the power of attorney | Reviewable: requires proof of the signatory's powers of the certificate | Binding for the registrar, not reviewable |
| Notarial legitimation of the zero balance certificate | Required as a registration requirement | Not required if the notary has already assessed the power of attorney |
| Application of art. 1,280.5 Civil Code | Applicable to the complementary requirements of the power of attorney | Its scope is clarified and limited by the resolution |
Economic and operational impact
The mechanism of irrevocable advance power of attorney has spread among banking entities precisely to reduce operational costs and time in mortgage cancellation: the bank does not need to intervene directly at the time of cancellation, delegating that management to the debtor themselves. This represents significant savings in internal management for banks and greater agility for debtors.
However, when registrars question the power of attorney or require additional documentation—as happened in this case with the Madrid no. 3 registrar—the process stalls, generating:
- Delays in the registry registration of the cancellation, with the consequent cost to the debtor (additional notarial fees, extra procedures, delays in related real estate operations).
- Legal uncertainty for notaries who have issued their judgment of sufficiency in good faith.
- Administrative costs for banking entities that must intervene later to remedy registry defects.
This resolution reduces that legal uncertainty and consolidates the advance power of attorney mechanism as a valid and agile route, which has direct impact on the thousands of mortgage cancellations processed annually in Spain under this scheme.
Who does it affect?
- Mortgage debtors who have finished paying their mortgage and want to cancel it registrally using the advance power of attorney granted to them by the bank.
- Banking entities (such as Banco Santander, the reference case in this resolution) that use the irrevocable advance power of attorney mechanism to streamline cancellations without direct intervention.
- Notaries who formalize mortgage cancellation deeds under this scheme and issue the judgment of sufficiency on the power of attorney.
- Property registrars who must qualify these deeds: the resolution defines the limits of their review authority.
- Management firms and law offices that process mortgage cancellations for individual or corporate clients.
Practical example
An individual has finished paying their mortgage with Banco Santander. At the time, when signing the loan, the bank granted them an irrevocable advance power of attorney so that, once the debt was settled, they could go to the notary themselves and execute the cancellation deed without the bank needing to intervene again.
The individual goes to the notary, who examines the power of attorney, issues their judgment of sufficiency and formalizes the cancellation deed. The notary incorporates the zero balance certificate issued by the bank. The deed is presented at the Property Registry.
Before this resolution, a registrar could—as the Madrid no. 3 registrar did—require proof of who signed that zero balance certificate and with what powers, blocking the registration. After this resolution, that blocking is not appropriate: the notarial judgment of sufficiency is binding and the registrar cannot require that additional documentation.
What should companies do now?
- Banks and financial entities: Review the models of irrevocable advance power of attorney granted to debtors to ensure they meet the requirements that allow the notary to issue a solid and unquestionable judgment of sufficiency. A well-drafted power of attorney avoids any subsequent registry discussion.
- Notaries: Document with precision the judgment of sufficiency in mortgage cancellation deeds under advance power of attorney, leaving express record of the elements of the power of attorney examined. This resolution supports their position, but the soundness of the judgment issued remains key.
- Mortgage debtors with paid-off mortgages: If your bank granted you an advance power of attorney and the registrar has blocked your cancellation requiring additional documentation on the zero balance certificate, this resolution is the legal argument to appeal that negative qualification.
- Management firms and law offices: Update the protocols for processing mortgage cancellations with advance power of attorney, incorporating this resolution as a reference in case of possible negative qualifications from registrars.
- Registrars: Adapt the qualification criteria for mortgage cancellation deeds under advance power of attorney to the doctrine established by this resolution, avoiding requiring requirements that the DGSJFP has declared inappropriate.
Frequently asked questions
What is the bank's irrevocable advance power of attorney to cancel a mortgage?
It is a power of attorney that the bank grants to the debtor themselves at the time of signing the mortgage—or later—so that, once the debt is paid, the debtor can go to the notary and cancel the mortgage registrally by themselves, without the bank needing to intervene again. It is an increasingly widespread mechanism among banking entities to streamline the process.
Can the registrar reject a mortgage cancellation if the notary has already validated the power of attorney?
No, according to this DGSJFP resolution. The notarial judgment of sufficiency on the irrevocable advance power of attorney is binding for the registrar and cannot be reviewed by them. The Madrid no. 3 registrar was corrected precisely for requiring proof of the signatory's powers of the zero balance certificate when the notary had already issued their judgment of sufficiency.
What is the zero balance certificate and what formalities must it comply with?
The zero balance certificate is the document issued by the bank that proves that the mortgage debt is completely paid. It acts as a complementary requirement of the advance power of attorney. This resolution clarifies the scope of the formalities required by art. 1,280.5 of the Civil Code for this type of document in the context of mortgage cancellation with advance power of attorney.
What do I do if the registrar has denied the registration of the mortgage cancellation?
If the registrar has issued a negative qualification requiring additional documentation on the advance power of attorney or the zero balance certificate, you can appeal that qualification to the General Directorate of Legal Security and Public Faith (DGSJFP), citing this resolution (BOE-A-2026-12685) as precedent. It is advisable to act with the notary who formalized the deed, as their judgment of sufficiency is the central argument.
Which banks does this resolution affect?
The reference case is Banco Santander, but the doctrine established is of general application to any banking entity that uses the irrevocable advance power of attorney mechanism for mortgage cancellations. Given that this mechanism is "increasingly widespread among banking entities," the resolution has impact on the banking sector as a whole.
