Spanish Citizenship by Descent: Complete Document Checklist

The documents required for Spanish citizenship by descent differ significantly depending on which route you are using. The parent route is manageable for most people. The Democratic Memory Law route is substantially more demanding. Get the checklist wrong and you waste months gathering documents that are incomplete, incorrectly apostilled, or missing from the file entirely.

Update: The Democratic Memory Law (Ley de Nietos) closed to new applications in October 2025. Applications filed before the deadline are still being processed, but grandchildren and great-grandchildren of exiles can no longer file new claims under it. The Spanish parent route is unaffected. See what the closure means.

This is the complete list for each route.

Universal Requirements (All Routes)

Regardless of which route you use, you will need:

  • Your valid passport (photocopy of all pages for the application; present the original at appointment)
  • Proof of legal residence in the consular district you are filing under (utility bill, lease, official ID showing address)
  • Your birth certificate — certified, apostilled if issued outside Spain, and translated into Spanish by a sworn translator if not already in Spanish
  • If married: marriage certificate, apostilled and translated
  • Passport photos meeting Spanish specifications (35mm × 45mm, white background, recent)

Route 1: Parent Was Spanish

In addition to the universal requirements above:

  • Parent’s Spanish birth certificate — issued by the Registro Civil where they were born in Spain; request directly from that Registro Civil or through the Registro Civil Central in Madrid
  • Proof that the parent held Spanish nationality at the time of your birth — this is typically satisfied by the Spanish birth certificate itself, but if your parent was born abroad of Spanish parents, you may also need their Spanish passport, DNI, or their own registration in the Registro Civil
  • Parent’s DNI or passport (if available) — not always required but strengthens the file
  • If the parent was born abroad: their Spanish consular registration (Registro de Matrícula Consular) from when they were registered with the Spanish Consulate in their country of residence

Key thing to check before you start: Confirm that your parent’s Spanish nationality has not lapsed. If your parent naturalized in another country before 2002 without formally retaining Spanish nationality, there may be a gap to address. Since 2002, Spanish law generally allows dual nationality — but the rules before that date were stricter.

Route 2: Democratic Memory Law

This route requires establishing two things: the Spanish origin of the qualifying ancestor AND the qualifying exile or loss-of-nationality circumstance. Both must be documented.

Documents proving the ancestor’s Spanish origin:

  • Spanish birth certificate of the grandparent or great-grandparent — from the Registro Civil in Spain where they were born, or from Spanish archival services if the original was lost or damaged
  • Baptismal certificate if civil registration records are missing (common for pre-Civil War births in rural areas)
  • Spanish consular registration in the receiving country (Mexico, Argentina, etc.) — consulates maintained registers of Spanish citizens abroad, and these records often survived even when Spanish civil records did not

Documents proving exile or qualifying loss of nationality:

  • Naturalization records in the country of exile — these often note “refugee” status, Republican exile organizations as sponsors, or other indicators of political flight
  • Records from Republican exile organizations (Ateneo Español de México, Casa de España, Junta de Auxilio a los Republicanos Españoles, etc.)
  • Ship manifests or entry records from the late 1930s–1940s in the receiving country
  • The Salamanca Archive (Archivo General de la Guerra Civil Española) in Spain — holds Republican-era political records, organizational files, and some personal documentation
  • Regional historical archives in Spain — the provinces of departure often have records of Republicans who left
  • Exile newspaper archives in Mexico and Argentina — exile communities were well-documented

Family chain documents (connecting you to the qualifying ancestor):

  • Birth certificate of your parent — showing the qualifying grandparent as a parent
  • If the qualifying ancestor is a great-grandparent: your grandparent’s birth certificate as well
  • All documents in the chain must be certified, apostilled, and translated into Spanish

Route 3: Second Generation Born Abroad (Under 21)

In addition to the universal requirements:

  • Parent’s Spanish birth certificate or proof that the parent had a Spanish parent
  • Documentation that the parent was born abroad (not in Spain)
  • Proof of your age (you must be under 21 at time of application)

Apostilles and Translations

Documents issued outside Spain must be apostilled under the Hague Convention before they are accepted by Spanish authorities. The apostille is obtained from the issuing country, not Spain.

All non-Spanish documents must be translated into Spanish by a sworn translator recognized by Spanish authorities. In the US, a translator certified by the American Translators Association (ATA) is generally accepted, but requirements can vary by consulate — confirm with yours before ordering translations.

Spanish civil registry documents (issued in Spain) do not need apostilles or translations — they are already in Spanish and issued by Spanish authorities.

Requesting Spanish Civil Registry Records

If your Spanish ancestor was born in Spain, their birth is recorded in the Registro Civil of the municipality where they were born. You can request a literal copy (certificado literal) of their birth entry:

  • Online: Through the Ministry of Justice website for the Registro Civil Central and some provincial registries
  • By mail: Writing to the specific municipal Registro Civil
  • In person: At the registry itself if you travel to Spain

For records from the 1930s and earlier, some civil registry offices were damaged or destroyed during the Civil War. In these cases, baptismal records from the parish church of the municipality may substitute, or the Salamanca Archive may have parallel records.

Common Reasons Files Are Rejected or Returned

  • Apostille obtained after the document was issued rather than from the original issuing authority
  • Translation completed by a translator not recognized in Spain
  • Birth certificates that are abstracts rather than literal certified copies (consulates typically require the full literal copy)
  • Documents in the family chain that do not clearly establish the parent-child relationship (different surnames, missing maiden names)
  • Missing evidence of the qualifying exile circumstance for Democratic Memory Law applications
  • Expired documents (some consulates reject documents older than 6 months)
