A clear, updated guide to Spain citizenship by descent in 2025, covering eligibility, required documents, application steps, and key legal considerations.
Spain citizenship by descent offers individuals with Spanish parents or, until recently, grandparents a pathway to European Union citizenship.
This comprehensive guide explains eligibility requirements, the recently expired Democratic Memory Law, required documents, application procedures, and the benefits of claiming your Spanish heritage in 2025 and beyond.
Spain citizenship by descent, also known as citizenship by origin (nacionalidad española por descendencia or nacionalidad por origen), allows individuals to claim Spanish nationality based on their bloodline connection to Spain. This pathway is grounded in the principle of jus sanguinis (right of blood), where Spanish citizenship passes through family lineage rather than birthplace.
Unlike naturalization, which requires years of residency in Spain and passing language and cultural exams, citizenship by descent recognizes your inherent right to Spanish nationality through your Spanish ancestors. However, Spain's descent program has specific limitations and, as of October 2025, has undergone significant changes that affect grandchildren's eligibility.
Spain's relationship with emigration spans centuries, creating one of the world's most significant diasporas. Understanding this history helps explain both Spain's citizenship by descent program and the recent temporary expansion through the Democratic Memory Law.
Following the Age of Discovery in the 15th and 16th centuries, Spain became one of Europe's first and largest emigrating populations. The rapid expansion of the Spanish Empire led to an unprecedented dispersal of Spanish people, primarily concentrated in the Americas, particularly New Spain (Mexico and Central America) and Peru. These colonial settlements established lasting Spanish-speaking communities throughout Latin America that maintain cultural and familial ties to Spain.
Between 1846 and 1932, nearly 5 million Spaniards emigrated to the Americas, mostly to South America, with Argentina and Brazil receiving the largest numbers. Economic hardship, rural poverty, urban congestion, and unpopular wars drove this massive outflow.
Spanish immigrants also settled in:
These communities created substantial diaspora populations that maintain connections to Spain today.
The Spanish Civil War (July 1936 - April 1939) represents the most traumatic chapter in modern Spanish history and created the largest wave of political exiles.
On July 18, 1936, a military uprising led by General Francisco Franco and other nationalist officers erupted against Spain's democratically elected Second Republic. The Republic had instituted progressive reforms including:
Conservative forces, including the military, Catholic Church, landowners, and fascist Falange party, opposed these changes and backed Franco's rebellion.
For nearly three years, Spain was torn apart. Republicans (including socialists, communists, anarchists, and moderate republicans) fought to defend the elected government. Nationalists (including military forces, monarchists, fascists, and Catholic conservatives) sought to overthrow it. The war was brutal, marked by massacres, executions, and bombing campaigns that foreshadowed World War II.
When Barcelona fell to Franco's forces on January 26, 1939, the end was near. The Republic's final collapse triggered a massive exodus.
Between January 28 and February 13, 1939, approximately 475,000 Spanish refugees, soldiers and civilians alike, crossed the Pyrenees into France in what became known as La Retirada (The Retreat).
Key facts about the exodus:
The reception in France was harsh. Despite being a fellow republic, France's government under Édouard Daladier feared the influx of "revolutionary reds." Refugees were separated, men were interned in makeshift camps on beaches at Argelès-sur-Mer and Saint-Cyprien with minimal shelter, while women, children, and elderly were dispersed across France. Conditions were deplorable, with inadequate food, sanitation, and medical care.
By mid-1939, 173,000 Spaniards remained interned in French camps. Many faced pressure to repatriate to Franco's Spain (not always voluntarily). Others tried to emigrate to Latin America, Mexico welcomed refugees but in limited numbers. Some Spanish Republicans stayed in France and later joined the French Resistance during World War II.
Franco's victory installed a repressive right-wing dictatorship that lasted until his death in 1975. The regime:
Exile status is presumed for all Spaniards who left Spain between July 18, 1936, and December 31, 1955. For departures between January 1, 1956, and December 28, 1978, proof of exile status must be provided.
During Franco's rule, hundreds of thousands of Spaniards could not return home and became permanent exiles in France, Latin America, the United States, and elsewhere. They lost or renounced Spanish citizenship, often under duress or due to naturalization requirements in their new countries.
The 1960s brought another major emigration wave as Spain's Stabilization Plan reduced wages and increased unemployment. Over 2 million Spaniards left for Northern Europe, primarily:
They sought better-paying jobs. This economic migration was encouraged by Franco's government to reduce unemployment and receive remittances from abroad.
As of January 1, 2025, according to Spain's Register of Spaniards Resident Abroad (PERE), 3,045,966 people with Spanish nationality live outside Spain, an increase of 4.7% from the previous year.
Major Spanish diaspora communities:
Latin America:
Europe:
Other Regions:
This extensive diaspora explains Spain's citizenship by descent programs, including the recent (now expired) expansion to grandchildren through the Democratic Memory Law.
CRITICAL UPDATE - OCTOBER 2025: The Democratic Memory Law (Grandchildren's Law), which allowed grandchildren of Spanish citizens to claim citizenship, expired on October 22, 2025. The application system is now closed and no longer accepting new applications. This section explains both current options (through parents) and the now-closed grandchildren pathway for historical context.
Claiming Through Spanish Parents (Still Available)
If you have at least one Spanish parent who was a Spanish citizen at the time of your birth, you likely already are a Spanish citizen by origin (nacionalidad por origen), even if you've never formally claimed it. Spanish nationality law prioritizes bloodline (jus sanguinis), not place of birth.
Key Requirements:
This is the most straightforward pathway. The process is essentially recognition of citizenship you already possess rather than acquisition of new citizenship. You need to register your birth with Spanish authorities and obtain documentation.
Age Considerations:
If you were born abroad to a Spanish parent (who was also born abroad), there are specific age windows:
Children born in Spain to at least one Spanish parent are automatically Spanish citizens.
Claiming Through Spanish Grandparents (NO LONGER AVAILABLE - EXPIRED OCTOBER 2025)
IMPORTANT: The pathway for grandchildren through the Democratic Memory Law (Law 20/2022), also called the Grandchildren's Law (Ley de Nietos), expired on October 22, 2025. No new applications are being accepted.
This temporary program (October 21, 2022 - October 22, 2025) allowed three specific categories of people to claim Spanish citizenship:
Category A: Descendants of Political Exiles
Children or grandchildren born outside Spain whose parent or grandparent was originally Spanish but lost or renounced Spanish nationality due to exile for:
Exile presumption: Anyone who left Spain between July 18, 1936, and December 31, 1955, is presumed to have been exiled. For departures between January 1, 1956, and December 28, 1978, proof of exile status must be provided.
Category B: Children of Spanish Women Who Lost Citizenship Through Marriage
Children born abroad to Spanish women who lost their Spanish nationality because they married non-Spanish individuals before Spain's 1978 Constitution came into effect (December 29, 1978).
Before 1978, Spanish law stripped Spanish women of their citizenship if they married foreigners. The Democratic Memory Law sought to correct this historical injustice.
Category C: Adult Children of Historical Memory Law Beneficiaries
Adult children of individuals who obtained Spanish nationality under the previous Historical Memory Law (Law 52/2007). The 2007 law had an age restriction (applicants had to be under 20 years old in some cases), so the Democratic Memory Law extended eligibility to those who "aged out" of the previous program.
Why This Law Existed:
The Democratic Memory Law was Spain's attempt at historical justice, allowing descendants of:
Between 2022 and 2025, thousands of descendants worldwide applied, particularly from Latin America, France, and the United States.
The law was initially set for two years (2022-2024) but was extended for one additional year until October 2025, with explicit statements that no further extensions would be granted.
Great-Grandchildren and Beyond
Spain does not allow direct claims through great-grandparents or more distant ancestors, and the Democratic Memory Law did not create this pathway either.

No. The Democratic Memory Law (Grandchildren's Law) that allowed grandchildren to claim Spanish citizenship expired on October 22, 2025. The application system is now closed and no longer accepting new applications. Only those who submitted applications before the deadline can continue with their cases.
Yes. If your parent was a Spanish citizen at the time of your birth, you likely already are a Spanish citizen and can register your citizenship. This pathway remains available and has no expiration date.
No. If claiming through a Spanish parent, there's no Spanish language requirement or cultural knowledge exam. These requirements only apply to naturalization pathways that require years of residency.
It depends on your current nationality. Spain has dual citizenship agreements with all Ibero-American countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela), Andorra, Philippines, Equatorial Guinea, and Portugal. Citizens of these countries can keep both nationalities. Those claiming citizenship under the (now-expired) Democratic Memory Law could also maintain dual citizenship. For other nationalities, Spain generally requires renunciation of your original citizenship during the oath ceremony.
For parent claims, the process typically takes 6 months to 2 years total. Processing times vary significantly by consulate, some process applications in 3-6 months, while others have backlogs extending to 2+ years.
Yes. Once you obtain Spanish citizenship, your children can claim Spanish citizenship through you as their Spanish parent. Children born after you become a Spanish citizen are automatically Spanish citizens. Children born before can apply for Spanish citizenship by descent through you.
If your Spanish parent naturalized in another country before you were born, they likely lost their Spanish citizenship at that time, breaking the chain. However, Spanish citizenship laws have changed over time, so consult with a Spanish immigration lawyer to evaluate your specific situation.
