Nationality for a child born in Spain: born here is NOT automatically Spanish

First separate the birth record from nationality

The child must have a Spanish Registro Civil birth record, but that inscription alone neither grants nor disproves Spanish nationality.

Check my child's nationality

The child usually first acquires the nationality of their parents (and is registered at their consulate) and must also be registered in the Spanish Registro Civil. “Usually” matters: the parents’ national laws decide whether nationality passes automatically, only after an act, or not at all.

If article 17 applies, the child is Spanish of origin; the registry records an existing status. Opción and nationality by residence are later forms of acquisition and follow different procedures.

Which route applies? Use this decision tree

• Spanish parent: a child of a Spanish father or mother is Spanish of origin under article 17.1.a, wherever born.
• Two foreign parents, child born in Spain: the child is Spanish of origin if one foreign parent was also born in Spain, except a child of a diplomatic or consular official accredited in Spain; also if both parents are stateless, neither parents’ law attributes nationality at birth, or filiation is undetermined (articles 17.1.b-d).
• Simple presumption: for the “neither law attributes nationality” case, the Civil Registry of the child’s domicile can declare Spanish nationality of origin with valor de simple presunción. It is an evidence-based registry proceeding, not a general nationality-by-birth application and not a fixed list of passports.
• Adoption: a foreign child under 18 adopted by a Spaniard becomes Spanish of origin from the adoption (article 19).
• Opción: among others, a person who is or was under the parental authority of a Spaniard, or whose father or mother was originally Spanish and born in Spain, may opt under article 20.
• Residence: a person born in Spanish territory qualifies for the shortened 1-year period, but the residence must be legal, continuous and immediately before the application. Birth registration and padrón are not legal residence.

Age decides who speaks and signs

• Under 14: for opción, the legal representative makes the declaration; disagreement between representatives goes to a voluntary-jurisdiction proceeding. For residence, the representative files only after Civil Registry authorisation following the Ministerio Fiscal’s opinion; disagreement over that application likewise goes to voluntary jurisdiction.
• From 14 to 17, unless emancipated: the child acts personally, assisted by the legal representative. A paper residence application is signed by the child and the representatives.
• The parental-authority option under article 20.1.a normally expires at 20 (with the Civil Code adjustment where personal law gives majority later). Only article 20.1.b has no age limit. Article 20.1.c points to two separate 2-year windows: late determination of birth or filiation under article 17.2, and adoption after age 18 under article 19.2.
• Minors under 18 do not sit CCSE or DELE. That is not an exemption from integration evidence: for the residence route, school-age children must provide the relevant school, training, residence or care-centre certificate.

Build a different evidence file for each route

• Always start with the child’s literal Spanish birth certificate and the identity, birth, nationality and representation documents of the child and parents.
• Simple presumption: prove the content and current effect of each known parent’s nationality law. A missing consular registration alone is not the test; the question is whether either law attributed nationality at birth. Keep written consular responses and proof of genuine attempts.
• Opción: add the Spanish parent’s birth/nationality record or the document establishing the relevant article 20 condition and parental authority.
• Residence: add the child’s passport or accepted identity document, TIE/residence evidence, the representative’s documents, Civil Registry authorisation where required and the school/integration certificate. The Ministry form can authorise official checks.
• Foreign documents need translation and legalisation/apostille only where applicable; treaties and EU law may remove or simplify either formality.

How to proceed without mixing the routes

1. Register the birth and obtain the literal Spanish certificate.
2. Check the exact nationality law of each parent at the date of birth before assuming either automatic nationality or statelessness.
3. Choose the legal route: origin/simple presumption at the Civil Registry, opción at the Civil Registry, or nationality by residence through the Ministry procedure.
4. Apply the under-14 or 14-to-17 signature rule and resolve parental disagreement before filing.
5. For residence, count 1 full year of legal, continuous residence immediately before filing; the statutory decision period is a different 1 year.
6. Track the application; for residence applications, a decision is followed by the oath and registration, where applicable.
7. After acquisition, make the corresponding Civil Registry entry and then obtain or update the DNI, Spanish passport and relevant records.

Common mistakes that change the result

• Treating the Spanish birth certificate, padrón, NIE and legal residence as interchangeable.
• Using an old internet “country list” instead of checking both parents’ current nationality laws and the child’s facts.
• Calling simple presumption a concession: if article 17.1.c applies, the child is Spanish of origin and the proceeding declares that status.
• Filing only in a parent’s name after the child turns 14, or mixing the under-14 routes: opción needs the representative and a court proceeding only if representatives disagree; residence needs prior Registry authorisation and the prosecutor’s opinion.
• Assuming the 1-year residence benefit expires. It does not; the error is counting a year that was not legal, continuous or immediately prior.
• Assuming “no exams” means “no integration evidence” for a school-age minor.

Denied or left without documents

• First identify what was refused: a Civil Registry declaration/option and a Ministry residence application do not use the same review path. Obtain the full decision and preserve its notification date.
• For an express refusal of nationality by residence, the ordinary choice is optional reposición within 1 month or direct contentious-administrative proceedings within 2 months. The 1-year negative-silence point is not an express decision and needs separate deadline analysis.
• If statelessness leaves the child without a passport, padrón, healthcare access or schooling, document every practical consequence and every unsuccessful request; do not treat another unproved application as a substitute for a timely challenge.
