Spanish Nationality by Option (Spanish Citizenship by Option)

Spanish nationality is a legal right that some foreign nationals can acquire when they meet specific conditions set out in Spanish law. Spanish nationality by option (also called Spanish citizenship by option) is one of the most important pathways for families—especially children of Spanish citizens, people who were under the legal authority of a Spaniard, and certain adoption or parentage scenarios. On this page, we explain what Spanish nationality by option is, who is eligible, deadlines and age limits, where to apply (Civil Registry vs consulate), documents required, and what happens after approval—so you can self-qualify and avoid costly mistakes.

What is Spanish Nationality by Option?

Spanish nationality by option is a legal pathway that allows certain people—typically based on a family link or legal authority relationship with a Spanish citizen—to acquire Spanish nationality by exercising a right of option under Article 20 of the Spanish Civil Code. In most cases, it is processed in person at the Civil Registry (Registro Civil) corresponding to the applicant’s domicile in Spain, or at the Spanish Consulate if the applicant resides abroad.

Unlike nationality by residence, which depends on years of legal residence and often requires exams, citizenship by option Spain is primarily a status-based route. The key is proving that your scenario fits the legal category and respecting any age windows and deadlines that apply.

Nationality by option vs other routes (quick comparison)

• By option (Article 20): Based on a specific family/legal authority scenario; deadlines can apply.
• By residence: Based on years of legal residence in Spain and other requirements; different process and evidence.
• By origin / “Spanish by origin”: A different legal category (not the same as option) with separate rules.
• Democratic Memory Law: A separate pathway with its own criteria and deadlines (often confused with option).
• Presumption / “simple presumption”: A distinct concept related to certain birth situations; not the same as option.

Am I Eligible? (Eligibility Scenarios Explained)

Eligibility for Spanish nationality by option requirements depends on your legal scenario. Below are the most common categories. If you’re unsure which one applies, focus on two questions: (1) what is your link to the Spanish citizen? and (2) what is your age and deadline window?

Who Has the Right to Opt?

• Persons under the guardianship of a Spanish citizen, with a two-year deadline from the age of majority or emancipation.
• Individuals with a Spanish parent or born in Spain, without any time limit.
• Persons whose parentage or birth in Spain is determined after turning 18 years old, with a two-year deadline from the determination.
• Individuals adopted by Spanish citizens after turning 18 years old, with a two-year deadline from the adoption.
• Children of Spanish parents of origin born in Spain, without any time limit.

Children of a Spanish citizen (including “parent became Spanish later”)

This is one of the most common Spanish citizenship by option scenarios. Many applicants are children of a Spanish citizen—sometimes the parent was already Spanish at the time of birth, and sometimes the parent acquired Spanish nationality later. The practical key is demonstrating the family link correctly and filing within the applicable time window, especially if the applicant is already an adult when the relevant status is established.

Applicants under parental authority, guardianship, or legal care of a Spaniard

If you were under the parental authority or guardianship of a Spanish citizen, the law may grant you the right to opt—but deadline rules often apply. Many delays happen because applicants misunderstand when the two-year window starts (majority/emancipation, or the legal determination date). A clear timeline is essential before you book appointments or legalise documents.

Adoption cases (what changes depending on age)

Adoption scenarios can be straightforward or extremely technical depending on timing. When adoption is recognised and the applicant is over 18, there is typically a two-year window to exercise the option. Document consistency (adoption decision, civil status inscriptions, identity matches) is critical to avoid requirements or refusal.

Common misconceptions (avoid expensive mistakes)

• “My grandparent was Spanish, so I automatically qualify.” Not necessarily. Option is scenario-based and not a universal “grandparent route.”
• “Born in Spain means Spanish citizenship.” Birth in Spain does not automatically grant nationality in all cases; the legal route depends on additional factors.
• “Option and residence are basically the same.” They are different routes with different requirements, timelines, and evidence.

The general deadline to exercise the option is 20 years, unless the age of majority is reached at 18 according to the individual’s personal law.

Deadlines & Age Limits (Don’t Miss the Window)

Deadlines are a major conversion and rejection risk because once the window is missed, the option route may no longer be available. The two most common deadline patterns are: (1) two years after reaching the age of majority or emancipation in certain guardianship/authority scenarios, and (2) two years from the date your parentage/birth/adoption is legally determined in specific cases.

Typical deadline rules (plain English)

• Two-year window: In certain cases, you must apply within two years after majority/emancipation or after the legal determination event.
• No deadline in certain scenarios: Some categories (as listed above) can apply without a time limit, depending on the exact facts.
• Age 20 reference: Some cases refer to a general expiry at age 20, with exceptions depending on personal law and scenario.

What if you missed the deadline?

If the option deadline has passed, the right strategy is to stop guessing and evaluate alternative nationality pathways based on your profile (for example, other family-based categories or nationality by residence where applicable). A short eligibility review can clarify whether you still have an option route or whether another route is safer.

Where to Apply: Civil Registry in Spain vs Spanish Consulate Abroad

One of the most searched “money questions” is: Where do I apply—consulate or Civil Registry for nationality by option? The answer depends primarily on where the applicant lives and where the civil status records are being handled. Below is a practical breakdown so you can choose correctly and avoid filing delays.

Apply in Spain (Registro Civil): process overview

If you live in Spain, the application is generally filed at the Civil Registry corresponding to your domicile. The process is usually in-person and appointment-based. Civil Registry workloads vary by city, so timeline expectations and appointment availability can differ significantly.

Apply abroad (Registro Civil Consular): process overview

If you reside outside Spain, you can generally file through the Spanish Consulate in your country of legal residence. Consular filing requires careful preparation of foreign documents (legalisation/apostille and sworn translations where required) and often involves additional waiting time due to internal coordination and appointment capacity.

Which is right for you? (mini decision tree)

• You live in Spain: Civil Registry filing is typically the correct channel.
• You live abroad: Spanish consulate filing is typically the correct channel.
• You are relocating soon: Strategy matters—filing location and timing can affect how fast your case moves.
• Your case involves documents from multiple countries: Plan legalisation and sworn translation early to avoid missing appointments or deadlines.

How to Apply for Spanish Citizenship by Option?

Application Process (Step-by-step)

The application is typically submitted in person at the Civil Registry corresponding to the applicant’s residence in Spain, following the proximity principle. If applying through a consulate, the process is also appointment-based and document-heavy. The practical key is correct sequencing: confirm eligibility → prepare documents → legalise/translate foreign documents → book appointment → submit → respond to requirements if any.

• In Spain: Applications for minors under 14 may require additional authorisation steps at the Municipal Civil Registry depending on the case and the registry’s criteria.
• Abroad: If you reside outside Spain, the application can be submitted at the Spanish Consulate in your country of origin or legal residence (Registro Civil Consular).

Deadline for Application

The right to opt for Spanish citizenship can expire two years after reaching the age of majority in certain scenarios, even if the applicant is incapacitated, as long as they were under the guardianship or legal authority of a Spanish citizen at some point. This is why timing analysis is essential before you invest in legalisation and translations.

Exception: Individuals whose parent is a Spanish national of origin and was born in Spain may be able to apply without any deadline, depending on the scenario and evidence.

Where Are the Procedures Carried Out?

• In Spain: At the Civil Registry of the applicant’s residence.
• Abroad: At the Spanish Consulate in the applicant’s country of residence.
• For minors or incapacitated persons: At the legal representative’s residence.

Required Documents (Checklist + Apostille/Translation Rules)

Users searching for Spanish nationality by option documents are usually stuck at one of two points: (1) what the Civil Registry/consulate will accept as proof of the scenario, or (2) how to prepare foreign documents correctly (apostille/legalisation and sworn translations). Below is a structured checklist and the most important compliance rules.

Documents Needed to Apply for Citizenship by Option for a Child

The process begins by submitting documentation that proves compliance with the legal requirements at the competent Civil Registry or consulate. Along with the declaratory data sheet for the citizenship oath (where required), the following documents are typically requested:

• Applicant’s Identification: DNI, passport, or another valid identity document (depending on your scenario and place of filing).
• Certificate of Residency (Certificado de empadronamiento): Issued by the municipality, confirming permanent and stable residence in Spain (when filing in Spain).
• Foreign Birth Certificate: Legalised or apostilled and translated by a sworn interpreter if not in an official language of Spain.
• Literal Birth Certificate of the Spanish Parent: Issued by the Spanish Civil Registry, proving the family relationship that supports eligibility for citizenship by option.

These documents are crucial for completing the procedure correctly. In practice, the strongest applications are those that also include clean evidence of identity consistency (names, dates, places) and any civil status links required for the scenario.

Foreign documents: apostille/legalisation + sworn translation

When documents come from outside Spain, they often require apostille or consular legalisation depending on the issuing country, and sworn translation when the document is not in Spanish (or a co-official language accepted by the authority). Getting this wrong is one of the most common reasons for delays and requirements.

Document issues we frequently fix (before you file)

• Name mismatches across certificates (order of surnames, spelling, accents, different transliterations).
• Missing or outdated civil registry certificates when the authority requires a recent issuance date.
• Incorrect legalisation method (apostille vs consular legalisation) for the issuing country.
• Translations not done by a sworn translator when required.
• Unclear evidence of the parent/guardian link in the specific option scenario.

Important Note: This checklist is for informational purposes. The Judge, Registrar, or Civil Registry officer may request additional information depending on your facts, your filing location, and the registry’s criteria.

Submission of the Citizenship by Option Application

• In Spain: Submit in person at the Civil Registry of your residence, typically with a prior appointment. Some authorities use a model application form provided by the Ministry of Justice.
• Abroad: Submit at the Spanish Consulate in your country of residence (Registro Civil Consular).
• For children under 14 years old: The application can usually be submitted by a parent or legal representative at their place of residence, following the applicable rules.
• For individuals over 14 years old: The applicant is typically required to be present for identity confirmation and key steps.

Processing Time, Costs, and What Happens After Approval

How long does Spanish nationality by option take?

People commonly search for Spanish nationality by option processing time because they need realistic expectations. Processing times vary significantly depending on the Civil Registry or consulate workload, appointment availability, and whether the file is complete from the start. A strong, consistent file reduces the chance of “requerimientos” and delays.

What causes delays (and how we prevent them)

• Missing or incorrect civil status evidence for the specific scenario.
• Foreign documents without proper legalisation/apostille or without sworn translation.
• Identity inconsistencies across documents (names, dates, places).
• Filing in the wrong place (Civil Registry vs consulate) or booking the wrong appointment type.
• Registry workload and appointment bottlenecks (varies widely by location).

After approval: registration → DNI → Spanish passport

Once nationality is granted, the next steps are usually: the corresponding Civil Registry inscription, then applying for a Spanish DNI (when applicable in Spain), and then your Spanish passport. If you reside abroad, you will typically register with the Consular Registry to proceed with passport issuance.

Once citizenship is granted, register with the Consular Registry to apply for a Spanish passport.

FAQs About Spanish Nationality by Option

1. What is Spanish nationality by option? Spanish nationality by option (Article 20 Civil Code) is a legal right that allows certain people—typically based on family ties or legal authority/guardianship links with a Spanish citizen—to acquire Spanish nationality if they meet the applicable requirements and deadlines.
2. Who is eligible for Spanish nationality by option in Spain? Eligibility depends on your scenario (children of Spanish citizens, guardianship/parental authority cases, certain adoption cases, and situations where parentage or birth in Spain is determined after age 18). The key is matching your facts to the correct legal category and respecting deadline windows.
3. Where do I apply: consulate or Civil Registry for nationality by option? If you live in Spain, you generally apply at the Civil Registry of your domicile. If you live abroad, you generally apply through the Spanish Consulate (Registro Civil Consular) in your country of legal residence. Your location and timing can influence strategy, especially if you are relocating.
4. What documents are needed for Spanish nationality by option? Typically, identification documents, proof of residence (when filing in Spain), the applicant’s birth certificate (legalised/apostilled and sworn translated if needed), and the Spanish parent/guardian’s civil registry certificate proving the link. Depending on your scenario, additional documents may be required to prove guardianship, adoption, or determination events.
5. How Does Citizenship by Option Differ from Citizenship by Residence? Citizenship by option is based on a qualifying family/legal-authority scenario and may involve strict age/deadline rules. Citizenship by residence is based on years of legal residence in Spain and has a different procedure and evidence requirements.
6. Can I opt for Spanish citizenship if I’m over 20 and don’t meet any exceptions? In many cases, no—because certain option rights expire by age and/or a two-year deadline window. However, the correct answer depends on your exact scenario and the applicable legal category, so an eligibility review is recommended before you assume you are excluded.
7. Do I have to renounce my current citizenship to obtain Spanish citizenship by option? This depends on your original nationality and whether your country allows dual citizenship. Spain’s rules and your home country’s rules can interact, so it’s important to check how your nationality is treated in practice before you take irreversible steps.
8. How long does the citizenship by option process take? Timelines vary widely depending on the Civil Registry or consulate, appointment availability, and whether your file is complete and consistent from the start. The most common delays come from document formalities, identity inconsistencies, and additional requirements from the authority.
9. What can I do if my citizenship by option application is rejected? If your application is denied, there may be appeal options depending on the decision and the procedural route. The best first step is to analyse the refusal reasoning and determine whether the issue is documentary, scenario-based, or procedural—then decide the appropriate remedy.
10. Is it necessary to speak Spanish to obtain citizenship by option? In many cases, Spanish language is not a formal requirement for nationality by option. However, procedural steps may require the applicant’s presence and identity confirmation, and practical communication at appointments can still be important depending on the authority.
11. Can I work in Spain while waiting for my citizenship by option application to be approved? Nationality by option does not automatically grant work authorisation while pending. Whether you can work depends on your current immigration/residence status in Spain. If you already hold a valid residence permit that allows work, you may continue working under that status.
12. Will my minor children also obtain Spanish citizenship if I acquire it by option? This depends on your children’s age, legal relationship, and the specific circumstances. Because family nationality situations can be technical, it’s recommended to review the family unit strategy rather than assuming automatic outcomes.
13. Is hiring a lawyer necessary to apply for Spanish citizenship by option? It is not always mandatory, but professional help can be decisive for deadline management, scenario qualification, document compliance (apostille/legalisation and sworn translation), and preventing delays due to inconsistencies or missing civil registry evidence.
14. Can a child apply for citizenship by option after turning 18? Some scenarios allow a limited window after reaching majority (commonly a two-year period), while other scenarios may not. The right answer depends on the legal category that applies to your case and the relevant determination dates.
15. Is there a specific application form for citizenship by option for those over 14? The authority will generally require an application containing personal details (name, birth details, identity number), the legal basis for the option route, and the supporting documents that prove the family/legal authority link. Applicants over 14 are typically required to attend key steps in person.
16. Can citizenship by option be requested after turning 18? Yes, in certain scenarios, especially where the right is exercised within an applicable deadline window after reaching majority or after the legal determination event. Because timing is decisive, a quick eligibility and deadline review is recommended before proceeding.
