What this document is
“Reclamación previa” is the official form of Spain’s National Social Security Institute (INSS). It is used to challenge an INSS decision on a benefit or pension: a refusal, the amount paid, a termination or a demand to repay money already received.
Under Article 71 of the Social Jurisdiction Act (Ley 36/2011, LRJS) this claim is mandatory before you can sue in the social court. The exception is a medical discharge (alta médica) issued by INSS after 365 days of sick leave, which follows a different procedure.
Who files it and where
- the person whose benefit was refused or wrongly paid — personally or through a representative;
- the claim is addressed to the INSS Provincial Directorate (Dirección Provincial) that issued the decision;
- the signed form is handed in at an INSS centre (CAISS) by appointment, at a public registry, or sent by post;
- deadline under Art. 71 LRJS: 30 days from notification of the decision (or from the date it is deemed refused by silence); for medical discharges that require this claim — 11 days.
What the form asks
One page: applicant details (two surnames, name, DNI/NIE/passport, Social Security number, phone, e-mail), home address, the date and file number (expediente) of the decision challenged, the facts and grounds of your disagreement, what you are asking for, place and date of signing and the province of the INSS directorate.
What to bring
- DNI, NIE/TIE or passport;
- a copy of the INSS decision you are challenging;
- documents supporting your case: work history report (vida laboral), employment contracts, medical reports;
- a second copy of the form — under Art. 71.7 LRJS it is stamped with the filing date, and you will need it in court.
