Quick Facts
Eligibility
Spain citizenship by descent is governed by Ley de Memoria Democrática · descent. The 2022 Ley de Memoria Democrática opened Spanish citizenship to descendants of exiles from the Civil War and Franco era. We handle both the historical-exile path and standard grandparent descent.
Eligibility for Spain citizenship by descent depends on three key factors: (1) the generational distance between you and your Spanish ancestor — most Spanish programs cover up to grandparent (3rd generation), but some go further; (2) whether the citizenship line was broken by naturalization in another country before the next child's birth in the line; and (3) the specific statute in effect at the time of each birth in the line.
Ancestra's written eligibility opinion addresses all three factors for your specific case, citing the exact statute and consular venue that applies. Our genealogists specialize in recovering the civil registry, parish, and consular records required to establish the unbroken lineage that Spanish nationality law requires.
Key constraints & rules
The #1 thing to know
The Memory Law window is expected to close in late 2025 or early 2026 — act quickly if you have Spanish exile ancestry. Exiles between 1936-1955 are presumed; 1955-1975 require proof of political motive.
Generational limit
Grandparent (3rd generation) for standard descent. The 2022 Democratic Memory Law has NO generational limit for descendants of Civil War/Franco-era exiles (children AND grandchildren).
Transmission rule
Both parents equally since 1978. Before 1978, paternal only.
Dual citizenship
Permitted for descent and Memory Law applicants. Spain generally requires renunciation for naturalized citizens, but this is not enforced for Ibero-American/Sephardic descent.
Language requirement
None for descent path.
Residency requirement
None for descent or Memory Law.
Filing authority
Ministerio de Justicia (Madrid) or Spanish consulate.
Key statute
Civil Code Article 22 (descent); Ley de Memoria Democrática (Law 20/2022), Article 23 (exile path)
Special paths available
