What this document is
MS-5 (“Solicitud de auxilio por defunción”) is the official form of Spain’s National Social Security Institute (INSS). It is used to claim a one-off payment that helps cover funeral expenses (gastos de sepelio) for whoever paid them.
If you also need a widow’s, orphan’s or family members’ pension, the form itself warns that a different model applies: MS-3 “Prestaciones de supervivencia”, which has its own funeral grant sections.
Who files and where
- the surviving spouse, the registered partner (pareja de hecho), children and relatives who habitually lived with the deceased;
- anyone else who paid for the funeral, with proof of payment;
- online at the Social Security e-office (digital certificate or Cl@ve) — the form is then not signed;
- a signed form — by post or at an INSS centre (CAISS) by appointment.
What the form asks
Seven pages: applicant details (relationship to the deceased, whether you lived together), the person acting for a minor or for someone with support measures, a representative, details of the deceased (date of death, whether a pensioner, Social Security number), language and notification address, statements, consents, bank account and signature. The last pages are instructions and data protection.
What to bring
- DNI, NIE/TIE or passport of the applicant and, if any, of the representative;
- the death certificate (certificado del acta de defunción);
- spouse, partner or cohabiting relative: the family book (libro de familia) or a kinship certificate from the Civil Registry; for a pareja de hecho, proof of registration;
- everyone else: proof of having paid the funeral (funeral home invoice);
- documents issued abroad must be legalised;
- a Spanish bank account (IBAN) in the applicant’s name.
