Insurance Claim Denied in Spain? How to Appeal

Spain combines a universal public health system with a large private insurance market. If your insurer — whether Sanitas, Adeslas, Asisa, Mapfre, or another company — has denied your claim, Spain's regulatory framework gives you clear rights to challenge that decision through free, accessible channels under the Ley de Contrato de Seguro (LCS — Law 50/1980).

Why Insurers Deny Claims in Spain

Spain's Sistema Nacional de Salud (SNS) provides universal healthcare to residents. However, over 12 million Spaniards hold private health insurance, and Spain has major markets for motor, home, life, travel, and business insurance. The principal regulator is the DGSFP (Dirección General de Seguros y Fondos de Pensiones) at dgsfp.mineco.gob.es. Common denial grounds include:

• Health insurance exclusions for pre-existing conditions: Insurers apply exclusion periods of 6–12 months; after 12 months, many exclusions expire automatically under LCS and standard policy terms; Article 3 LCS provides that exclusion clauses not specifically highlighted at inception are unenforceable
• Motor insurance liability disputes: Fault attribution is the most common ground for motor denial; the LCS and Reglamento General de Circulación (Royal Decree 1428/2003) govern the evidentiary standards; dashcam footage and the European Accident Statement (Europeo de Accidente) are critical evidence
• Home insurance maintenance exclusion disputes: Property damage denied on "inadequate maintenance" grounds when the actual cause was a sudden insured event; Article 20 LCS interest penalties create strong incentive to resolve these disputes promptly
• Life insurance non-disclosure: Article 10 LCS requires willful concealment for a full denial — innocent non-disclosure of conditions unknown to the policyholder at application is not sufficient grounds for voiding coverage
• Travel insurance rejection of emergency care: Pre-existing condition exclusions applied to emergency treatment; under Article 3 LCS, prejudicial clauses must be specifically highlighted at policy inception to be enforceable
• Dental and vision coverage disputes: Spanish private health plans frequently exclude or limit dental procedures; disputes arise at the boundary between preventive, restorative, and cosmetic dental care

How to Appeal

Step 1: File a formal reclamación with the Servicio de Atención al Cliente or Defensor del Asegurado

Under DGSFP regulations, every insurer must have a Servicio de Atención al Cliente. File your reclamación in writing, citing the specific LCS clause supporting your position, attaching all supporting evidence, and stating the specific outcome you are seeking. The insurer must respond within 1 month (insurance companies) or 2 months (financial institutions). Request the response in writing.

Step 2: Reference Article 20 LCS for delayed payment

If your valid claim has been withheld beyond 3 months from the loss event, explicitly reference Article 20 LCS in your reclamación. Interest accrues from 3 months at the legal rate; after 2 years the interest rate rises to 20% per year. These penalties are among the strongest anti-delay provisions in Europe and must be formally claimed in writing to be enforceable.

Step 3: Escalate to the Defensor del Asegurado

If the Servicio de Atención al Cliente response is unsatisfactory, escalate to the insurer's Defensor del Asegurado — the independent internal ombudsman whose favorable decisions bind the insurer. The Defensor must respond within 2 months. This step is typically required before filing with DGSFP.

Step 4: File a complaint with the DGSFP Servicio de Reclamaciones

After exhausting the internal process, file at dgsfp.mineco.gob.es online or by registered letter. Include all correspondence, policy documents, and the denial letter. DGSFP investigates whether the insurer violated Spanish insurance law. While DGSFP decisions are recommendations rather than binding court orders, insurers comply in the vast majority of cases. The process is free and takes 3–6 months.

Step 5: Apply contra proferentem under Código Civil Article 1288

Ambiguous policy terms are interpreted against the insurer under Código Civil Article 1288 — the Spanish expression of the contra proferentem principle. If the denial relies on an exclusion or policy provision that is unclear or could reasonably be read in your favor, explicitly invoke this principle in your appeal.

Step 6: Civil court proceedings for unresolved disputes

For amounts under €2,000 the procedimiento verbal applies; higher amounts use the procedimiento ordinario. Spain has justicia gratuita (legal aid) for lower-income claimants. Article 20 LCS interest penalties make litigation economically attractive if the insurer has been slow to pay a valid claim.

What to Include in Your Appeal

• Your insurance policy condiciones generales and condiciones particulares
• Formal denial letter with the insurer's specific grounds and policy references
• Medical specialist letter (for health claims), police report (for motor claims), or expert report (for property claims)
• Calculation of Article 20 LCS interest if payment has been delayed beyond 3 months
• Timeline of all communications with the insurer since the claim was first submitted
• Reference to any exclusion clause you contend was not specifically highlighted at inception per Article 3 LCS
