Mortgage law in business loans: when it applies if there are individual guarantors

Key data

A company in the music sector requested financing from Institut Català de Finances with mortgage guarantee on a single-family home owned by the company. The transaction included as guarantors a corporation and several individuals linked to the borrowing company. The property registrar of Palafrugell suspended registration because the individual guarantors had not received the transparency information required by the Law 5/2019 on Real Estate Credit Contracts.

The lending entity argued that, as it was a business loan, the LCI was not applicable. The General Directorate of Legal Security and Public Faith (DGSJFP) rejected that argument and confirmed the suspension, following doctrine already established since 2019.

What does this regulation establish?

The DGSJFP resolution clarifies a rule that many financial entities and companies continue to ignore:

Law 5/2019 applies to a mortgage loan even if the borrower is a commercial corporation, provided that these two conditions are met simultaneously:

• The mortgage is on a residential property (dwelling).
• Individuals act as guarantors or sureties, even if in a personal capacity and even if the borrowing company is a corporation.

In that scenario, the transparency requirements of the LCI must be met at least with respect to individual guarantors. This includes the delivery of pre-contractual documentation, prior notarial advice and the transparency deed, among other procedures of the LCI protocol.

The DGSJFP does not innovate: it applies consolidated doctrine since 2019. What is relevant is that it reaffirms it against an argument that continues to be used in practice: that the business nature of the loan excludes the LCI. That argument does not work when there are individual guarantors.

Economic and operational impact

The impact is not a direct fine, but its economic consequences can be equally serious:

• Registration blockage: If LCI requirements are not met, the registrar suspends mortgage registration. Without registration, the real guarantee does not exist against third parties.
• Financing paralysis: The company cannot access the loan or does so under conditions of legal uncertainty until the defect is remedied.
• Remediation costs: Repeating the notarial process, gathering guarantors again, generating new documentation and resubmitting to the registry for qualification involves additional time and fees.
• Risk of clause nullity: Clauses agreed in violation of the LCI may be declared null, affecting the financial structure of the transaction.
• Project delays: In transactions linked to investment or business activity, delays in registration can have significant opportunity costs.

Who does it affect?

• Companies (any size and sector) that mortgage a residential property they own to obtain financing and have individual guarantors (partners, administrators, family members).
• Financial entities and lenders (banks, public credit entities such as Institut Català de Finances, debt funds) that formalize business mortgage loans with personal guarantors.
• Notaries that must apply the LCI transparency protocol also in these transactions.
• Property registrars, who have the obligation and power to suspend registrations when LCI compliance is not demonstrated.
• Financial and legal advisors who structure business financing transactions with mortgage guarantee.
• Individual guarantors (partners, administrators, spouses) who guarantee their companies' loans with guarantee on residential property.

Practical example

A company in the music sector—exactly the case resolved by the DGSJFP—requests a loan from Institut Català de Finances. The guarantee is a single-family home owned by the company itself. To strengthen the transaction, the company administrator, his spouse and another partner sign as personal guarantors, in addition to a related corporation.

The lending entity considers that, as it is a business loan, it does not need to apply the LCI protocol: it does not deliver the European Standardized Information Sheet (FEIN) to individual guarantors, does not summon them before a notary for the transparency deed, and does not comply with the pre-contractual information deadlines required by Law 5/2019.

Result: the Palafrugell registrar suspends registration. The mortgage is not registered. The company cannot demonstrate the real guarantee against third parties. The transaction must be redone from the notarial stage, with the costs and delays that entails. The DGSJFP confirms that the registrar acted correctly.

The solution would have been simple: apply the LCI protocol from the start to all individual guarantors, regardless of the business nature of the loan.

What should companies do now?

1. Review ongoing transactions: If your company has pending formalization or registration of a mortgage loan on a residential property with individual guarantors, verify whether the complete LCI protocol has been applied to those guarantors.
2. Require the LCI protocol from the bank or lender: Before signing, confirm that the financial entity will deliver the FEIN and other pre-contractual documentation to all individual guarantors and that the notarial transparency deed will be executed.
3. Inform the guarantors: Individual guarantors must know their rights under the LCI. If they have not received pre-contractual information, registration may be suspended.
4. Coordinate with the notary: Ensure that the notary applies the LCI protocol also for the guarantors, not just for the borrower. The transparency deed must reflect that all individual guarantors have been advised.
5. Consult with specialized legal advisor: If you already have a registered business mortgage with personal guarantors and have doubts about its validity, consult whether the process was carried out correctly to avoid surprises in the event of execution or refinancing.
