Case law and legal doctrine agree that registration of the assignment is an essential procedural requirement for the assignee‑creditor to exercise the mortgage enforcement action. To benefit from the rights of the registered mortgage holder, registration is mandatory; merely producing the deed of assignment is insufficient.
In the realm of real rights (derechos reales), contractual freedom prevails, and even without registration, the holder of the assigned credits may exercise its rights if it proves ownership in declaratory proceedings.
However, to initiate mortgage foreclosure, the Civil Procedure Act (LEC) requires strict compliance with Articles 10 and 685 LEC, and legal doctrine is unanimous:
👉 There is no alternative way to prove standing for mortgage enforcement other than registration.
Any enforcement order (auto de admisión) based on unregistered standing would be null, and so would any procedural act derived from it.
Another interpretative approach holds that involving the Land Registry in acts affected by such nullity would be incorrect, pursuant to Articles 538.2, 549, and 550 LEC.
Under Article 688 LEC, when enforcement is brought against mortgaged property, the court must request from the Registrar a certification including:
- ownership of the property
- all real rights over it
- all existing encumbrances
- a complete list of all registered charges
This necessarily presupposes that the party initiating the enforcement appears as the registered mortgage holder.
Land Registry Limits and the Principle of Rogation
The Registrar cannot act ex officio, nor can the Registrar enter ownership or mortgage rights in favour of an assignee—no matter how public or well‑known—due to the principle of rogation (Article 6 Mortgage Law – LH).
Similarly, a Registrar cannot accept a judicial order referring to a claimant who is not registered as the mortgagee.
The enforcement action under Article 130 LH contains procedural requirements that only allow enforcement based on the content of the registered title.
Thus, the lack of active standing (legitimación activa) in mortgage foreclosures where the credit assignment does not appear in the Land Registry may be assessed:
- at the request of a party, or
- ex officio.
Supreme Court Doctrine
The Supreme Court, in its judgment of 20 July 2004, held that lack of active standing, although preliminary to the merits, may and must be examined ex officio by the judge.
A securitisation fund (or any assignee) may exercise actions derived from ownership of the credit under Article 1526 Civil Code, but cannot exercise the mortgage enforcement action under Article 130 LH unless it is the registered mortgage holder.
Recent Reforms and European Case Law
Mortgage enforcement procedures have undergone recent reforms due to their strict and exclusive grounds of opposition.
The Court of Justice of the European Union (CJEU) has held that the executive nature of enforcement proceedings cannot prevent a national judge from examining the unfairness of contractual terms, even after judgment and before eviction.
This principle was reaffirmed by the Spanish Constitutional Court, STC 31/2019 (Full Court), 28 February, No. 1086/2018.
Conclusion
- A securitisation fund cannot initiate mortgage foreclosure unless the mortgage is registered in its name.
- Producing the assignment deed does not suffice to prove standing in mortgage foreclosure.
- Any enforcement order based on unregistered standing is null, along with all subsequent procedural acts.
- Judges must examine standing ex officio, especially when the assignment is not registered.
- The assignee may enforce the personal action on the credit, but not the real action (mortgage enforcement) unless registered.
