Debt Collection Letter Spain (Carta de Reclamación de Deuda)

A Debt Collection Letter Spain (Carta de Reclamación de Deuda) is a formal written demand through which a creditor (acreedor) formally requires a debtor (deudor) to pay an overdue obligation, specifying the outstanding principal, accrued interest, and costs, and warning of legal action if payment is not made within a specified period. In Spain, the legal basis for debt collection demands is primarily the Código Civil (Real Decreto de 24 de julio de 1889 — CC), specifically Article 1100, which provides that the debtor is in mora (default) when the creditor formally demands performance of the obligation — making the interpelación judicial or extrajudicial (formal demand) the legal act that triggers mora debitoris (debtor's default) and the obligation to pay default interest under Article 1108 CC.

Article 1100 CC distinguishes between obligations that produce automatic mora (mora automática) — where the obligation specifies a fixed payment date — and obligations that require a formal demand to trigger mora. For obligations with a specific maturity date, the debtor is automatically in default from the day following the due date without any demand being necessary. For obligations without a fixed term, the formal demand — which the Carta de Reclamación de Deuda constitutes — is the act that places the debtor in mora and starts the running of default interest under Article 1108 CC.

Default interest (interés de mora) in Spain is governed by two distinct regimes depending on the nature of the debt. For civil debts (deudas civiles) between private individuals or between a consumer and a business, default interest is governed by Article 1108 CC — where the parties have not agreed an interest rate, the default rate is the legal interest rate (interés legal del dinero) set annually by the Ley de Presupuestos Generales del Estado — for 2024, the legal interest rate is 3.25% per annum. For commercial debts (deudas mercantiles) between traders, Ley 3/2004 (LMOC) establishes a higher default rate — 11.10% per annum for the first half of 2024 — accruing automatically from the payment due date under Article 6 LMOC.

Debt collection activities in Spain are regulated to prevent harassment and abusive practices. The Ley Orgánica 3/2018 (LOPDGDD) and Reglamento (UE) 2016/679 (RGPD) restrict the processing of debtor personal data for collection purposes — the Agencia Española de Protección de Datos (AEPD) has sanctioned debt collection agencies for inclusion of individuals' data in publicly accessible credit files without proper legal basis. The Registro de Morosos — private credit registries such as ASNEF (Asociación Nacional de Establecimientos Financieros de Crédito) and RAI (Registro de Aceptaciones Impagadas) — are regulated by the LOPDGDD.

The legal framework governing the Debt Collection Letter Spain (Carta de Reclamación de Deuda) in Spain draws on several key statutes and regulatory bodies. Under the Ley Cambiaria y del Cheque (Ley 19/1985), promissory notes and bills of exchange are governed in Spain. The Banco de España supervises banking under Ley 10/2014. The Comisión Nacional del Mercado de Valores (CNMV) regulates securities markets. The AEAT administers IVA (Ley 37/1992) and IRPF (Ley 35/2006). The Ley 3/2004 governs late payment in commercial transactions with statutory interest. Parties executing a Debt Collection Letter Spain (Carta de Reclamación de Deuda) in Spain should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Código Civil (Real Decreto de 24 de julio de 1889), Article 1100 sets the foundational requirements.

A Debt Collection Letter Spain is needed whenever a creditor wishes to formally demand payment of an overdue obligation from a debtor who has failed to pay on time or at all.

The letter is required when a payment obligation with a fixed due date has not been met and the creditor wishes to formally place the debtor in mora under Article 1100 CC, triggering default interest and starting the limitation period for enforcement.

A Debt Collection Letter is needed when a landlord wishes to demand payment of overdue rent (renta atrasada) from a tenant under Ley 29/1994 de Arrendamientos Urbanos (LAU) — the letter is the first step before commencing a desahucio por falta de pago (eviction for non-payment) procedure under Article 250.1.1 LEC.

The letter is required when a lender wishes to demand repayment of a personal loan (préstamo personal) or credit facility that has matured or on which the borrower is in arrears.

A Debt Collection Letter is needed when a creditor wishes to include a debtor in a private credit registry (ASNEF, RAI) — the AEPD requires prior written notification of the outstanding debt to the debtor before inclusion in a credit registry, and the Carta de Reclamación de Deuda serves as this notification.

The letter is required when a creditor wishes to interrupt the prescription period — under Article 1973 CC, sending a formal extrajudicial demand interrupts prescription and restarts the applicable limitation period from zero.

A Debt Collection Letter is needed when a freelancer (autónomo) or small business is owed payment for professional services rendered and the client has not paid within the agreed or statutory period — the letter triggers LMOC late payment interest at 11.10% per annum for commercial debts.

The Comisión Nacional del Mercado de Valores (CNMV) regulates securities markets. The AEAT administers IVA (Ley 37/1992) and IRPF (Ley 35/2006). The Ley 3/2004 governs late payment in commercial transactions with statutory interest. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.
