Many foreign nationals dream of reconnecting with their Spanish roots. If that’s your case, you can apply for Spanish citizenship by descent and recover a lost part of your family’s identity.
But there’s a catch: this path involves more than having a Spanish last name or family story. It requires paperwork, legal proof, and precise filing of specific forms. Let’s go step by step.
What does it mean to apply for Spanish citizenship by descent through family ties?
This legal route lets you claim Spanish nationality through your parents or grandparents. It isn’t automatic. You must meet certain conditions and submit the right documents.
Several factors determine eligibility:
- Your parents’ or grandparents’ place of birth
- Their nationality at the time of your birth
- Whether they renounced or lost Spanish nationality
- If they left Spain due to war or political exile
You’ll also need to prove your family link using official certificates and complete the corresponding forms at a consulate or Civil Registry.
Key eligibility scenarios
You may apply if you fall into one of these categories:
| Family Link | Condition |
|---|---|
| Child of a Spanish national | Parent was Spanish at your birth |
| Born abroad to a Spanish-born parent | One parent was born in Spain and retained nationality |
| Descendant of exiles | Grandparents lost nationality due to political or ideological exile |
| Child of Spanish woman married before 1978 | Mother lost nationality through marriage to a foreigner |
These cases are not the only ones. Some may qualify under transitional provisions, especially through the Democratic Memory Law.
Required forms and supporting documents
The main challenge lies in the paperwork. Spanish authorities require very specific formats and translations.
Here’s a breakdown of the most important forms:
| Form Name | Purpose |
|---|---|
| EX-01 or EX-02 | Used for general nationality applications |
| Model 790, Code 026 | Payment form for processing fees |
| Official affidavit | Declaration of descent and link to Spanish citizen |
| Civil Registry request | Form for registration of nationality acquisition |
All documents must be translated into Spanish and legally certified. Some may require Hague Apostille or consular legalisation.
You will also need:
- Birth certificates (yours and your ancestor’s)
- Marriage certificate if applicable
- Proof of your ancestor’s Spanish nationality
- Proof of exile or forced renunciation (if relevant)
- Criminal background checks
- Empadronamiento (if residing in Spain)
When descent is not enough
Even if your grandfather was Spanish, you may not qualify. Why? Because Spanish law often prioritises transmission of nationality from parent to child, not across multiple generations.
If your parent didn’t claim nationality, you might lose your chance—unless an exception applies. These exceptions are tricky and often misunderstood.
For example, a person whose grandfather left Spain during the dictatorship may still qualify under special rules. But you must provide records showing exile and prove the family link with precision.
Common delays and mistakes
Many applicants submit incomplete or wrongly filled forms. This causes rejections or long delays. Others fail to legalise foreign documents or miss key deadlines.
These are the most frequent errors:
- Submitting birth certificates without Apostille
- Using old or unofficial translations
- Forgetting the payment form
- Applying through the wrong consular office
- Not providing proof of parent’s nationality at birth
Spanish consulates are strict. They check every detail. One missing stamp can block your file for months.
What if you apply from outside Spain?
You don’t need to live in Spain to apply. You can submit your file at the Spanish consulate in your country. But you still must follow the exact same procedure.
If approved, your data will be registered in the Registro Civil Central. You’ll then swear allegiance to the Spanish Constitution. After that, you can apply for your national ID and passport.
But beware: timelines vary greatly by consulate. Some offices take up to 18 months or more, especially in Latin America.
How the Democratic Memory Law affects your case
The Democratic Memory Law (Law 20/2022) opened new doors. It lets descendants of exiles claim nationality, even if their parents never did.
This applies mostly to families affected by the Spanish Civil War or Franco-era dictatorship. The deadline to apply under this law has been extended until October 2025.
To benefit from this option, you must submit:
- Proof of exile (political, ideological, religious, or sexual identity)
- Birth and marriage certificates
- Statement explaining the family’s exile story
This law also helps children of Spanish women who lost nationality before 1978 due to marriage to foreigners. But each case must meet strict documentation rules.
Frequently asked questions about applying for Spanish citizenship by descent
Can I apply for Spanish citizenship by descent if my parent never claimed their nationality?
Yes, in some cases you can. Spanish law allows applicants to claim nationality even if their parent didn’t formalize theirs—but only under certain exceptions.
For instance, if your parent was eligible but never filed for Spanish nationality, and you can prove your link to a grandparent who was originally Spanish, you may qualify through the Democratic Memory Law.
This law was created to correct historical injustices, especially for families affected by political exile. Still, your case must meet strict documentation and historical criteria. You can’t apply based solely on family tradition or last name—you must present official evidence.
Every case is reviewed individually, and outcomes depend heavily on your paperwork. This is why legal assistance is often key.
What happens if I submit the wrong version of a form?
Submitting the wrong form—or an outdated version—is a common mistake. Unfortunately, it can delay or even block your application.
Spanish consulates require current, official forms, properly filled out and signed. They also expect printed copies, not digital scans or handwritten edits.
If you send the wrong version of, say, the Model 790 (Code 026) or fail to attach the payment proof, your file may be returned or left pending. Worse yet, they might not notify you immediately, which leads to long delays.
To apply for Spanish citizenship by descent without setbacks, make sure you download the most recent forms directly from official sources or consult a legal expert who keeps track of changes.
Do I need to be fluent in Spanish to apply for citizenship by descent?
No, you do not need to pass a Spanish language test if you apply for Spanish citizenship by descent. That requirement only applies to residency-based applications.
When your claim is based on ancestry, the focus is on legal connection and documentation—not integration. You won’t be asked to take the DELE or CCSE exams if your descent case falls under the Civil Registry rules or the Democratic Memory Law.
However, some consular officers may require that you understand basic legal documents. It’s not an official test, but communication may still be needed. That’s why many applicants seek legal help, especially when they don’t speak Spanish fluently. It ensures nothing gets lost in translation.
What if I was adopted by a Spanish citizen?
If you were legally adopted by a Spanish citizen, you may apply for Spanish citizenship by descent under special conditions.
The law distinguishes between minor and adult adoptees. If you were adopted before the age of 18, your case is stronger and often processed through the Civil Registry as an option-based nationality request.
If you were over 18 at the time of adoption, you must usually show two years of legal residence in Spain before applying. However, if the adoption took place during the Spanish citizen’s exile or is linked to historical events, special provisions may apply.
These cases often require additional documents—like the adoption ruling, identity certifications, and proof of cohabitation—and must be reviewed carefully before submission.
What law governs the right to apply for Spanish citizenship by descent?
The right to apply for Spanish citizenship by descent is mainly governed by Law 20/2022, also known as the Democratic Memory Law.
This law expanded nationality rights for descendants of Spaniards who suffered exile due to the Civil War or Franco-era persecution. It also includes provisions for children of women who lost their Spanish nationality by marrying foreigners before 1978.
Besides Law 20/2022, some applications rely on Law 52/2007 (Historical Memory Law) or are processed under articles of the Spanish Civil Code, particularly when handled through consulates and civil registries.
The responsible authorities include the Ministry of Justice, the Civil Registry, and Spanish consulates abroad. Each office may interpret the law slightly differently, so the procedure often varies depending on where the file is submitted.
You may qualify—but your documents must prove it
Having Spanish ancestors is one thing. Proving it to Spanish authorities is another. The law provides opportunities—but only if you build a solid file, form by form.
Even small errors—like using outdated formats or forgetting to legalise a document—can slow you down for months or force you to start over.
That’s why many applicants choose not to navigate this process alone. Spanish nationality through descent is a legal right, but also a legal challenge.
If your roots lie in Spain, don’t let bureaucracy bury them.
Act now, prepare with precision, and make sure your claim is treated seriously from the first step.
