Commercial Claim Letter Spain (Carta de Reclamación Comercial)

A Commercial Claim Letter Spain (Carta de Reclamación Comercial) is a formal written instrument through which one Spanish business (empresario) asserts a legal claim against another business arising from a commercial transaction — defective goods, non-conforming services, unpaid invoices, breach of a supply agreement, or failure to comply with a commercial contract. In Spain, commercial claims between traders (reclamaciones mercantiles) are governed principally by the Código de Comercio (Real Decreto de 22 de agosto de 1885 — CCom), specifically Articles 57 through 63 regulating the execution of commercial contracts and Article 59 governing the form of commercial communications, supplemented by the general law of obligations in the Código Civil (CC) Articles 1088 through 1314.

Article 59 of the Código de Comercio provides that commercial contracts shall be binding from the moment of acceptance of the offer, and that commercial communications — including demands and claims — shall be in writing when the amount at stake requires documentary evidence for judicial enforcement. The Código de Comercio distinguishes commercial acts (actos de comercio) from civil acts — commercial transactions between traders are presumed to be commercial acts, subjecting them to the CCom's specific provisions on warranties, delivery, inspection, and prescription periods.

For sales of goods between traders in Spain, the warranty and conformity regime under Articles 327 through 345 of the Código de Comercio applies, distinct from the consumer protection regime in the TRLGDCU. Under Article 336 CCom, the buyer must inspect goods within 4 days of delivery and must notify the seller of apparent defects within that period — failure to inspect and notify within 4 days may forfeit the buyer's warranty claim for apparent defects (vicios aparentes). Hidden defects (vicios ocultos) must be reported within 30 days of discovery under Article 342 CCom.

The Ley 3/2004, de 29 de diciembre, por la que se establecen medidas de lucha contra la morosidad en las operaciones comerciales (LMOC), implementing EU Directiva 2011/7/UE on combating late payment in commercial transactions, is critical for Spanish commercial claim letters involving unpaid invoices. Under Article 4 LMOC, the maximum payment period in commercial transactions is 30 days for private-sector buyers and 30 days for public-sector entities, extendable to 60 days by written agreement. Late payment automatically triggers statutory interest at a rate set semi-annually by the Ministerio de Hacienda — for the first half of 2024, the late payment interest rate is 11.10% per annum under Article 7 LMOC.

The Juzgado de lo Mercantil, established under Ley Orgánica 8/2003, de 9 de julio, para la Reforma Concursal, has exclusive jurisdiction over commercial disputes (litigios mercantiles) in Spain, including claims between traders, insolvency proceedings, and competition law disputes. Before filing in the Juzgado de lo Mercantil, Spanish procedural law encourages alternative dispute resolution — mediation under Ley 5/2012, de 6 de julio, de Mediación en Asuntos Civiles y Mercantiles, and arbitration under Ley 60/2003, de 23 de diciembre, de Arbitraje.

The legal framework governing the Commercial Claim Letter Spain (Carta de Reclamación Comercial) in Spain draws on several key statutes and regulatory bodies. Under the Ley de Sociedades de Capital (LSC) RDL 1/2010, the Registro Mercantil maintains the register of Spanish companies. The Código de Comercio 1885 governs commercial obligations. The Agencia Estatal de Administración Tributaria (AEAT) administers Impuesto sobre Sociedades (IS) under Ley 27/2014. The Comisión Nacional de los Mercados y la Competencia (CNMC) enforces competition law. The Código Civil governs general contractual obligations under Article 1255. Parties executing a Commercial Claim Letter Spain (Carta de Reclamación Comercial) in Spain should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Código de Comercio (Real Decreto de 22 de agosto de 1885), Article 59 sets the foundational requirements.

A Commercial Claim Letter Spain is needed whenever one Spanish business has a formal legal claim against another business arising from a commercial transaction and wishes to assert that claim in writing before commencing formal legal or arbitral proceedings.

The letter is required when a buyer has received goods that do not conform with the contract specifications — wrong quantity, wrong quality, damaged in transit, or not matching the agreed samples — and wishes to formally notify the seller within the 4-day inspection period under Article 336 of the Código de Comercio to preserve warranty rights.

A Commercial Claim Letter is needed when a service provider has failed to complete a contracted service to the agreed specifications or within the agreed time, and the client wishes to demand remedy or compensation before commencing mediation or court proceedings before the Juzgado de lo Mercantil.

The letter is required when a supplier's invoice has not been paid within the agreed payment period — or within the 30-day statutory maximum under Ley 3/2004 (LMOC) — and the creditor wishes to formally demand payment, specify the late payment interest accrued at the LMOC statutory rate, and warn of legal action.

A Commercial Claim Letter is needed when a commercial debt is approaching the prescription period — the Commercial Claim Letter formally interrupts prescription under Article 1973 CC, restarting the 3-year prescription period under Article 943 CCom from the date of dispatch.

A Commercial Claim Letter is needed when a distributor or agent has received defective stock, failed to comply with sales targets, or breached exclusivity provisions — the manufacturer or principal uses the letter to formally assert its contractual rights before initiating arbitration or mediation under the applicable commercial contract dispute resolution clause.

Parties in Spain should prepare a Commercial Claim Letter Spain (Carta de Reclamación Comercial) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under the Ley de Sociedades de Capital (LSC) RDL 1/2010, the Registro Mercantil maintains the register of Spanish companies. The Código de Comercio 1885 governs commercial obligations. The Agencia Estatal de Administración Tributaria (AEAT) administers Impuesto sobre Sociedades (IS) under Ley 27/2014. The Comisión Nacional de los Mercados y la Competencia (CNMC) enforces competition law. The Código Civil governs general contractual obligations under Article 1255. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A valid and effective Commercial Claim Letter Spain under the Código de Comercio and applicable commercial law must include the following essential elements.

Claimant Identification: Full legal name, NIF/CIF, registered address (domicilio social), Registro Mercantil reference, and CNAE activity code of the claimant business. The name and position of the authorised signatory must be stated.

Respondent Identification: Full legal name, NIF/CIF, and registered address of the business against whom the claim is made. Addressing the letter to the respondent's legal representative or responsible department improves the likelihood of a prompt response.

Contract or Transaction Reference: A precise description of the commercial transaction giving rise to the claim — contract number, date, invoice references, delivery notes (albaranes), purchase order numbers, or any other documentary reference that uniquely identifies the underlying transaction.

Description of the Claim: A clear, factual, and specific description of the breach or failure — what was agreed, what was delivered or performed, and how the delivery or performance deviates from the contractual standard. For goods quality claims, reference to the agreed technical specifications, quality standards (normas UNE, ISO, or CE marking requirements) should be included.

Quantification of Loss: A specific monetary quantification of the claim. Under Article 1101 CC, the claimant must prove both the breach and the quantum of loss — attaching supporting documentation strengthens the claim.

Late Payment Interest: For unpaid invoices, the letter should calculate and claim statutory late payment interest under Ley 3/2004 (LMOC) at the rate published by the Ministerio de Hacienda — currently 11.10% per annum for the first half of 2024.

Deadline for Payment or Remedy: A clear and reasonable deadline for the respondent to pay the claimed amount, remedy the defect, or propose an acceptable settlement.

Prescription Interruption: A statement that the letter formally interrupts the applicable prescription period under Article 1973 CC.

Dispute Resolution: Reference to the dispute resolution clause in the underlying contract — arbitration under Ley 60/2003, mediation under Ley 5/2012, or the jurisdiction of the Juzgado de lo Mercantil.
