If your mortgage has been assigned to a fund and you want to negotiate or exercise the right of retraction, you need to know the assignment price. The problem: the General Directorate of Legal Security and Public Faith (DGSJFP) has just confirmed that this data is not public by default. The resolution of July 21, 2026 (published November 5, 2026, reference BOE-A-2026-23217) dismisses the appeal of a property owner who attempted to know the individualized price at which her mortgages were assigned to the funds LSF11 Boson and Sirocco Lux.
The resolution is not an isolated case: it establishes doctrine applicable to all mortgage debtors in the same situation.
What does this resolution establish?
The DGSJFP establishes three clear rules that every mortgage debtor and advisor must know:
- The assignment price is sensitive patrimonial data. It is protected by data protection regulations. The registrar has the obligation to weigh it before including it in any certification or formal registry note.
- Legitimate interest must be concrete, direct and accredited. It is not sufficient to allege generic interest ("I am the debtor and I want to know it"). You must justify before the registrar that knowledge of the price is necessary to exercise a right recognized by law, in a specific and documented manner.
- The appeal cannot expand the scope of the initial application. The appellant did not expressly request the price in her original application, but claimed it for the first time in the appeal. The DGSJFP confirms that this is not admissible: what is not requested in the application cannot be demanded through appeal.
In summary: the price can only be published when its knowledge is necessary to exercise a right recognized by law, and that necessity must be justified expressly and previously before the registrar.
| Element | Criterion applied by the DGSJFP |
|---|---|
| Assignment price in registry publicity | Not included by default; is protected patrimonial data |
| Legitimate interest to obtain it | Must be concrete, direct and accredited before the registrar |
| Time to request it | In the initial application, not in the subsequent appeal |
| Required justification | Necessity to exercise a right recognized by law |
| Generic interest ("I am the debtor") | Insufficient; does not enable publication of the price |
Economic and operational impact
This doctrine has direct consequences on the negotiating capacity of mortgage debtors whose debt has been sold to funds:
- Negotiation of discounts: Knowing the assignment price allows the debtor to know how much the fund paid for his debt and, therefore, what negotiating margin exists. Without that data, negotiation starts at a disadvantage.
- Right of retraction: In certain legal cases, the debtor can subrogate in the position of the assignee by paying the assignment price. If that price is not accessible, the practical exercise of retraction becomes extremely complicated.
- Procedural cost: Obtaining the data through judicial or administrative means requires accrediting legitimate interest rigorously, which implies legal advisory costs and time.
- For assignee funds (such as LSF11 Boson and Sirocco Lux), this resolution strengthens the protection of their sensitive commercial information against registry publicity requests.
Who does it affect?
- Mortgage debtors whose mortgage has been assigned to an investment fund or assignee entity.
- Credit assignee funds (such as LSF11 Boson and Sirocco Lux, mentioned in the case) that acquire mortgage portfolios.
- Property registrars, who must apply this weighting criterion before issuing certifications with the assignment price.
- Lawyers and advisors who manage mortgage negotiation or retraction processes on behalf of debtors.
- Financial entities that assign credit portfolios and have an interest in the confidentiality of the agreed price.
Practical example
A property owner has two mortgages assigned to the funds LSF11 Boson and Sirocco Lux. She requests from the Property Registry of Majadahonda No. 1 a certification that includes the individualized price at which each fund acquired her mortgages. The registrar issues the certification without including that price.
The property owner appeals to the DGSJFP. However, in her original application she had not expressly requested the price — she claims it for the first time in the appeal. The DGSJFP dismisses the appeal for two cumulative reasons:
- The assignment price is protected patrimonial data that the registrar must weigh before publishing.
- The scope of the appeal cannot be expanded with respect to what was requested in the initial application.
Practical lesson: If a debtor needs the assignment price to exercise retraction or negotiate a discount, he must request it expressly in the initial application to the registry, accrediting in a concrete and documented manner the legal right he intends to exercise with that data. If he does not do so, he will lose the possibility of obtaining it through appeal.
What should those affected do now?
- Mortgage debtors: If your mortgage has been assigned and you need the assignment price, request it expressly in the initial application to the registry — never leave it for the appeal. Indicate in a concrete and documented manner the legal right you intend to exercise (retraction, negotiation, etc.).
- Advisors and lawyers: Review all registry publicity requests in progress that involve assignment prices. If it was not expressly requested in the application, the appeal route is closed according to this doctrine.
- Registrars: Apply the weighting criterion before including the assignment price in any certification, assessing whether the applicant has accredited a concrete and direct legitimate interest.
- Assignee funds: This resolution strengthens the protection of your acquisition prices. Properly document the confidentiality of the price in assignment contracts to facilitate the registrar's work.
- All affected parties: Consult a professional specialized in mortgage and registry law before initiating any registry publicity request procedure that involves assignment data.
Frequently asked questions
Can I know the price at which a fund bought my mortgage?
Yes, but not automatically. According to the DGSJFP resolution of July 21, 2026, the assignment price is protected patrimonial data. To obtain it you must accredit before the registrar a concrete, direct and documented legitimate interest — for example, that you need that data to exercise the right of retraction. Generic interest ("I am the debtor") is not sufficient.
What happens if I did not request the price in my initial application and I claim it in the appeal?
The DGSJFP rejects it. The resolution expressly confirms that the appeal cannot expand the scope of the initial application. If you did not request the price in your original application to the registry, you cannot claim it for the first time through appeal. You will have to initiate a new properly formulated application.
What funds were involved in the case resolved by the DGSJFP?
The specific case that originated resolution BOE-A-2026-23217 involved the funds LSF11 Boson and Sirocco Lux, to which the mortgages of the appellant property owner had been assigned. The doctrine established, however, is of general application to any mortgage assignment to funds.
How should I accredit legitimate interest before the registrar to obtain the assignment price?
You must justify in a concrete manner that knowledge of the price is necessary to exercise a right recognized by law. It is not sufficient to be the debtor: you must specify what right you intend to exercise (for example, legal retraction) and provide documentation that supports that necessity. The interest must be direct, not hypothetical or generic.
What registry processed the case and who issued the certification without the price?
The case was processed by the property registrar of Majadahonda No. 1, who issued the certification without including the assignment price. The DGSJFP confirmed that the registrar's action was correct in weighing the protection of the data before including it in formal publicity.
