Nationality for a child born in Spain: born here is NOT automatically Spanish
Being born on Spanish soil does not make a child Spanish automatically — Spain has no general ius soli. But there are real routes: Spanish nationality of origin if one foreign parent was also born in Spain (art. 17 Civil Code), opción (art. 20), nationality by residence with only 1 year for those born here, and an anti-statelessness rule for children who would otherwise be stateless. This guide explains which route fits, the documents, and why CCSE/DELE exams do not apply to small children.
Born in Spain is not automatically Spanish
Spain has no general ius soli: a child born here to two foreign parents is, as a rule, not Spanish just for being born on Spanish territory.
Check my child's nationality — free
The child usually first takes the nationality of the parents (registered at their consulate), and must be inscribed at the Spanish Registro Civil.
Spanish nationality then comes through a specific route — Spanish of origin under art. 17, opción, residencia or the anti-statelessness rule — not automatically.
The four real routes
- Spanish of origin (art. 17 CC): if the child is born in Spain and at least one foreign parent was also born in Spain (except children of diplomats/consular officials), the child is Spanish of origin.
- Opción (art. 20 CC): e.g. a child under the patria potestad of someone who acquires/recovers Spanish nationality, or whose parent was originally Spanish and born in Spain — the child can opt for it.
- Nacionalidad por residencia — 1 año: a child born in Spanish territory needs only 1 year of legal residence (instead of 10), through their legal representative.
- Anti-statelessness: a child born in Spain who would otherwise be stateless (apátrida) — because their parents' country does not grant them nationality — is Spanish of origin.

Opción vs por residencia
- Opción is a declaration, made by the legal representative for a minor, when the legal condition exists (art. 20). It is faster and tied to a specific family link.
- Por residencia (1 año) is a full nationality application based on the child having legal residence and being born here — it needs the residence to be documented.
- For a child the procedure is done by the legal representative; the CCSE and DELE exams do not apply to small children — they are required for adult applicants by residence, not for minors.
Documents you need
- The child's birth certificate (inscribed at the Registro Civil) showing birth in Spain.
- Parents' identity and residence documents (passports, NIE/TIE) and the family link.
- For the 1-year route: proof of the child's legal residence in Spain and municipal registration (empadronamiento).
- For opción: the document proving the art. 20 condition (e.g. a parent originally Spanish, or acquiring nationality).
How to apply
- Register the birth at the Registro Civil (this does not by itself give Spanish nationality).
- Identify the route: Spanish of origin (art. 17), opción (art. 20), residencia 1 año, or anti-statelessness.
- Gather the documents and check the child has documented legal residence (for the residence route).
- The legal representative files the declaration of opción or the residence application.
- Track the file; for residence applications the resolution and oath/inscription follow.
- Once granted, inscribe the Spanish nationality and update DNI / passport / padrón.
Common mistakes
- Assuming the baby is Spanish just for being born in Spain — there is no general ius soli.
- Confusing opción with nationality by residence — they have different conditions.
- Letting the 1-year residence route lapse by not documenting the child's residence.
- Thinking the child must pass CCSE/DELE — those exams are for adults by residence, not small children.
Denied or stuck
- If an application is denied, there is a recurso — check the exact ground (route, residence proof, deadline) before re-filing.
- If the child risks being stateless, raise the anti-statelessness rule explicitly with the documents from the parents' country.

Children's nationality FAQ
Is a child born in Spain automatically Spanish?
No. Spain has no general ius soli — the child needs a specific legal route or condition (art. 17 origin, opción, residence or the anti-statelessness rule).
What if one foreign parent was also born in Spain?
If the child was born in Spain and at least one foreign parent was also born in Spain, the child is Spanish of origin, except in diplomatic or consular cases.
What is opción (art. 20)?
A declaration to acquire nationality when a legal condition exists — e.g. being under the patria potestad of someone who becomes Spanish, or having a parent originally Spanish born in Spain.
How long for the residence route?
A child born in Spanish territory needs only 1 year of legal residence, instead of the general 10.
What if the child would be stateless?
If no other country grants the child nationality, they are Spanish of origin under the anti-statelessness rule.
Do CCSE and DELE apply to my child?
No — those exams are for adult applicants by residence. They do not apply to small children.
Does registering the birth give nationality?
No. Registering at the Registro Civil is mandatory, but nationality exists only if a legal route or condition applies.
Who files for a minor?
The legal representative (usually a parent) files the opción declaration or the residence application.
Can the child keep the other nationality?
It depends on the route and the other country's rules — check your specific case.
