In Cantabria, the application of late fees and interest for delayed rent is governed by the principles of contractual freedom within the limits set by the Ley de Arrendamientos Urbanos (LAU) and the Spanish Civil Code. Landlords must be cautious when drafting penalty clauses, as "abusive" or disproportionate fees can be declared null and void by the Juzgados de Cantabria.
Rent Payment Deadlines
According to Article 17 of the LAU, rent must be paid within the first seven days of each month unless a different date is agreed upon. It is a common misconception that this is a "grace period"; in reality, failure to pay on the agreed due date (or by the 7th if unspecified) constitutes immediate default (mora). While a formal demand is often required to trigger interest, the breach occurs as soon as the deadline passes.
Contractual Penalties and Abusive Clauses
Landlords may include a clause specifying penalties or interest for late payments. In Cantabria, these are viewed as "liquidated damages" (cláusulas penales).
- Judicial Interpretations: There is no statutory cap (e.g., 10%) in the LAU. However, courts in Cantabria frequently strike down penalties exceeding 10-15% of the monthly rent as "abusive" under consumer protection principles.
- Usury Laws: Interest rates significantly higher than the average market rates for consumer loans can be challenged under the Ley de Represión de la Usura.
- Civil Code Supplementary: If the contract is silent, the landlord can only claim the legal interest rate (interés legal del dinero), updated annually by the government.

Debt Recovery and Eviction
Late payment of rent is sufficient grounds to initiate eviction. Under the Ley de Vivienda (12/2023), landlords must comply with new procedural requirements, including checking for tenant vulnerability. If the tenant is found to be in a vulnerable situation, the eviction process in Cantabria can be significantly delayed while social services intervene.
Legal Formalities in Cantabria
The most critical step for a landlord in Cantabria is the Burofax. This serves as a formal demand for payment and as essential evidence for potential judicial action. The Burofax must clearly state the debt and provide a deadline for payment to avoid the "enervation" of any subsequent eviction.
