Requirements for Spanish nationality by residency in 2026

What nationality by residency means

Nationality by residency is the route the vast majority of adult foreigners use to become Spanish. It isn't the only path, but it's the most common one, and it's the one this guide covers.

The other paths exist, though they cover narrow situations. Nationality by origin applies to anyone born to a Spanish mother or father, or born in Spain to stateless parents. Nationality by option is for children of Spanish nationals who didn't get the nationality at birth, adopted children, and a few similar cases. Carta de naturaleza is granted by the government for exceptional reasons (athletes who win medals for Spain, high-profile humanitarian cases), and you don't apply for it: you receive it. There was also a special route for descendants of Sephardic Jews, with an application window that formally closed in 2019, although some old files are still in process.

Residency is different. You file your application, hand in every document they ask for, prove you've spent the minimum legal time living in Spain, and wait for a resolution. If everything checks out, the Registro Civil calls you in to swear the Constitution and you become Spanish. If something is missing or your record has a problem, they deny the application and you start a different story.

The minimum residency time varies a lot depending on your country of origin and your personal situation. Some people need ten years, others only two, and mixed marriages can bring it down to one. That's the first number you need to figure out before you start gathering paperwork.

Years of residency required based on your nationality

The law sets four categories. The one that applies to you depends on the passport you currently hold or your family situation, not on how long you've already been in Spain.

Two years. If your passport is from an Iberoamerican country, Andorra, the Philippines, Equatorial Guinea, or Portugal, two years of continuous legal residency is enough. The Latin American list covers Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, the Dominican Republic, Uruguay, and Venezuela. Descendants of Sephardic Jews also apply through this two-year route now, not through the special 2019 window that's already closed.

One year. Applies to the spouse of a Spanish national after one year of marriage, without legal or de facto separation. It also applies to widows or widowers of a Spanish national if they were living together when the partner died. And to anyone born on Spanish territory who didn't have the right to another nationality at birth, or children of a Spanish national of origin even if they weren't born Spanish themselves.

Five years. For refugees with status recognized by Spain. Filing for asylum isn't enough on its own; you need the status already granted.

Ten years. Everyone else. If your country doesn't fall into the categories above, this is your road. It covers most European, Asian, and African countries, plus the United States, Canada, Australia, and many more.

A word on "continuous": the years count continuously and immediately before the application. You can't add up scattered chunks of your life in Spain with big gaps in between. If you lived here for three years, went back to your country for four, and came back, you're not at seven years; you're starting again from your return.

Short trips don't break continuity. A two-week family visit, a long weekend, a summer month at home in August: none of that hurts you. The problem is long absences. If you spend six months or more outside Spain, especially without keeping clear ties (job here, current empadronamiento, active contracts), they can decide you broke residency and you'll start counting again from your return.

Documents you'll need

The file has a personal side (your own papers) and an administrative side (certificates you request here in Spain). This is what you'll gather.

Valid passport, original and a photocopy. If it's close to expiring, renew it before filing because they'll need it valid at several points in the process.

Literal birth certificate from your country of origin, apostilled under the Hague Convention or legalized through consular channels if your country didn't sign the Hague. If it isn't in Spanish, it needs a sworn translation by a translator appointed by the Spanish Ministry of Foreign Affairs (MAEC). Any old translation won't do. The apostille has to be done in the issuing country, not in Spain.

Criminal record certificate from your country of origin, apostilled and translated if needed. Validity is typically 3 to 6 months from the issue date, so don't request it too early or it'll expire before you file.

Spanish criminal record certificate. You request it for free through the Ministry of Justice electronic office (sede.mjusticia.gob.es). It takes minutes if you have a digital certificate. Validity is also 3 to 6 months.

Historical empadronamiento certificate from the town hall where you live. This is different from the regular empadronamiento: the historical one lists every address where you've been registered and the exact dates. You need it to prove your continuous years of residency. If you've moved within Spain, make sure the historical certificate captures every address with no gaps.

Marriage certificate if you're the spouse of a Spanish national, plus your spouse's documents as the case requires. If your marriage was celebrated outside Spain, this certificate also needs apostille and sworn translation.

Current CCSE diploma. The certificate from the Instituto Cervantes constitutional and sociocultural knowledge exam is valid for 4 years from the pass date. If you passed earlier than that, you'll have to retake it.

DELE A2 diploma or equivalent, if you aren't a native Spanish speaker. Anyone from a Spanish-speaking country is exempt; everyone else has to prove A2 level through DELE or a recognized equivalent.

Paid fee. Modelo 790 código 026, 104,05 euros. You pay it online by card or through online banking, then upload the receipt to the file. The fee isn't refunded if your application is denied or you withdraw it.

Proof of economic means. Updated work history (vida laboral), employment contract if you're employed, IRPF tax returns from the last few years, or equivalent documents if you're self-employed. This shows economic integration and that you aren't a burden on the system.

Depending on your specific case, they can ask for extra documents: certifications of studies you did in Spain, bank account certificates, rental contracts to reinforce your local roots. The list isn't closed; the official reviewing your file can request whatever they consider relevant.

How to file the application

The entire process is handled online through the Sede Electrónica del Ministerio de Justicia (sede.mjusticia.gob.es). There's no paperwork to drop off at an office anymore and no in-person appointment to register the file. The application is signed electronically from home.

To enter the sede you need a digital certificate or DNIe. The DNIe is for Spanish citizens, so foreigners use the digital certificate from the FNMT (Fábrica Nacional de Moneda y Timbre). You get the certificate in two steps: you request the code online on the FNMT website, then go in person to an accreditation office (Agencia Tributaria, Seguridad Social, and several others handle this) with your NIE, and within minutes you download the certificate to your computer from home.

Once the certificate is installed in your browser, you log in to the Ministry of Justice sede, pick the nationality by residency procedure, fill out the form, upload every document as a PDF, pay the fee, and sign electronically. The system assigns you a file number (número de expediente) and that's it, you've filed.

Lawyers and gestores offer to handle the file for you. It isn't required, but if you get tangled up with the apostille or the sworn translations, or if your case has any complication (international marriage, criminal record entries you aren't sure whether to declare, residency with gaps), it can save you a lot of headaches. A well-filed application by a competent professional is worth what it costs. A badly filed one by a random gestoría can cost you dearly in time and denials.

Common mistakes that slow down or sink the file

Three errors come up again and again in files that get returned or denied. Knowing what they are, you can dodge them without effort.

The first is submitting expired criminal record certificates. Validity is typically 3 to 6 months from the issue date, not from the date you decided to request them. If you pull them in January and file in August, the certificates are already expired when the official opens the file, and they get rejected. The practical rule is to request the criminal records as close to the filing date as possible, once you have the rest of the paperwork ready.

The second is empadronamiento with gaps. If you moved from Madrid to Valencia and took three months to register at the new address, your historical certificate shows a three-month gap with no empadronamiento. From the ministry's point of view, that counts as a potential break in residency. The way to avoid it is to register quickly every time you change addresses. The way to catch it before filing is to pull the historical certificate from the town hall and read it carefully: if you spot a gap, try to patch it with rental contracts, bills in your name, or any other proof of continuity. Much better to fix it before filing than to receive a formal request from the ministry two years later.

The third mistake is submitting documents from your country of origin without an apostille or without a sworn translation. Any foreign document that arrives at the ministry without a Hague Convention apostille (or consular legalization if your country didn't sign the Hague), and without a sworn translation by a translator appointed by the MAEC, is treated as if it doesn't exist. You can't apostille an Argentine document in Spain: the apostille is done in the country that issued the document, by the authority designated there. Anyone who tries to skip this step always ends up ordering the documents again, losing months, and sometimes paying twice for international shipping.

How long it takes and what happens next

The legal maximum to resolve is 12 months from the date the complete file is submitted. That's what the law says. The reality is different: most files take 12 to 36 months, and in peak periods the ministry has reached 4 years. That isn't invented statistics, that's the complaint of everyone who's been through it.

While you wait, keep your empadronamiento current. If you move, register at the new address right away. Don't leave Spain for long periods: even after filing, the ministry can verify your continuity of residency up to the moment of the resolution, and if they spot long absences during the wait, they can deny you.

When the resolution arrives, you get an electronic notification on the Sede. Check in every few weeks, because if you don't open the notification within ten days it's considered read automatically. If the resolution is unfavorable, they explain the reason and you have deadlines to appeal. If it's favorable, you receive the nationality grant, but you aren't Spanish yet: you still have to swear.

From the date of the favorable resolution, you have 180 days to go to the Registro Civil for your local district and swear (or promise) the Constitution and fidelity to the King. Miss that deadline and the grant expires, meaning you start the whole file again from zero. It's a shame to lose years of paperwork for failing to book a fifteen-minute appointment, so as soon as the favorable notification arrives, request your Registro Civil slot right away.
