Spanish nationality for your family: spouse, minor children, and other cases

If you're Spanish, your family has doors open

One of the most concrete advantages of getting Spanish nationality is that it opens much faster paths for your spouse and your minor children. They don't have to wait the 2 years required for Ibero-Americans or the 10 years required for non-EU citizens that you had to complete yourself. The law recognizes that the family should follow the same path, and it cuts the timeframes drastically.

That said, not all family members are in the same situation. A spouse follows one path, a 14-year-old child another, a 22-year-old child no special path at all, and a grandchild of a Spaniard yet another. Each relationship and each age has its own procedure, its own paperwork, and its own timeframes. Mixing them up is the most common mistake families make, and it costs months of returned applications.

This guide walks through each case separately so you know exactly what applies to each member of your family and in what order to move. If you still don't have clarity about what applies to you as the main applicant, review the general requirements first so you don't mix procedures and end up with a folder of papers that don't match the right track.

Spouse: 1 year of marriage is enough

Your spouse can apply for Spanish nationality with just 1 year of completed marriage and legal residency in Spain during that same year. It's one of the most generous reductions in the entire framework: instead of the 2 years for Ibero-Americans or the 10 years for everyone else, 1 year is enough.

That said, conditions matter. The marriage must be active, with no legal separation and no de facto separation. If you've separated even without formal paperwork, technically the requirement of an active marriage breaks down and the application can fall through. The administration usually cross-checks the joint padrón registration to confirm cohabitation, so don't underestimate how much paperwork they look at.

The procedure is practically the same as the general residency one:

• Approved CCSE certificate.
• DELE A2 certificate if your spouse isn't from a Spanish-speaking country.
• Criminal record certificate from the country of origin, apostilled and translated.
• Historical padrón certificate proving continuous legal residency.
• Fee of 104.05 euros (the same one you paid).

The only thing that changes is the required prior residency period. All the documentation and the cost are identical to what you went through.

A particular case: if your spouse is the widow or widower of a Spaniard, and you were living together at the moment of death, the 1-year regime still applies even though there's no longer an active marriage. The law protects this situation because the bond was considered active until the very last day.

Important: registered domestic partnership (pareja de hecho), even though it grants rights to residency, healthcare, and inheritance in many regions, does NOT grant the right to nationality by reduced residency. Only formal marriage opens this path. If you've been living together for years without a marriage certificate, you'd need to get married first and wait 1 year from the wedding date. It's a detail that surprises many couples with fully shared lives, and it has no exceptions written into the law.

Minor children: the fast track via option

For children under 18, there's a path that isn't even residency, but option. It's a shorter procedure, cheaper, and with fewer requirements. It only works while they're still minors, so the clock matters a lot.

Three typical situations:

• Minor with 1 year of legal residency in Spain and a Spanish parent: your child can exercise their right of option to Spanish nationality. You get your nationality, you wait until they've completed 1 year registered in the padrón with you in Spain with legal residency, and you apply for the option. There's no CCSE exam or DELE A2 required for the child. There's no criminal record needed if they're a minor.
• Minor born in Spanish territory: in many cases they have a right to Spanish nationality of origin automatically or by option, depending on the parents' nationality at the moment of birth. If both parents were foreigners and neither transmitted their nationality to the child, Spain grants it to avoid statelessness. If you acquire nationality later and the child was born here, their situation reopens with more favorable conditions.
• Minor adopted by Spanish parents: Spanish nationality is automatic from the moment the adoption becomes final. There's no additional procedure.

The option is applied for at the Civil Registry of the municipality where the minor resides. You file it as a parent with parental authority. The basic documents are these:

• Literal birth certificate of the minor, apostilled and translated if foreign.
• Padrón certificate of the minor in Spain.
• Marriage certificate or parentage certificate linking the minor to the Spanish parent.
• Photocopy of your Spanish DNI as the parent.
• Valid passport of the minor.

The fee is free or very reduced depending on the region. Nothing like the 104.05 euros of the general residency procedure. The typical resolution time runs from 6 months to 2 years, depending on the Civil Registry and its workload. Madrid and Barcelona usually take longer; small municipalities resolve faster. Plan around that, because a slow registry can hold your entire family timeline hostage.

Once the option is approved, the minor receives their birth certificate registered in the Spanish Civil Registry and can process a DNI and passport like any other Spaniard.

Children over 18: bad news

If your children are already adults when you get nationality, they don't benefit from your procedure. They have to apply for nationality on their own like any other foreign adult, with their own complete file:

• 2 years of legal residency if they come from an Ibero-American country. Most usually fall in this group because they inherited your previous nationality, so that helps them.
• 10 years of legal residency if they come from a country not included in the Ibero-American group.
• Their own CCSE and DELE A2 certificates (if they're not native Spanish speakers).
• Their own fee of 104.05 euros.
• Their own criminal record from the country of origin.

There's no shortcut. The condition of "child of a Spaniard" stops having a special effect once the child is an adult. For the administration, an adult over 18 with a Spanish parent is exactly the same as an adult over 18 without one. What does count is that their legal residency in Spain is usually already consolidated from before, so the 2-year period tends to be met quickly.

There's a valuable window if you have children close to 18: file the option BEFORE they turn 18. Even if it seems early, Civil Registry resolution times are long and it's better to submit the application while they're still minors. Once the application is signed while the child is a minor, the procedure continues its course even if they turn 18 during processing. It's a key difference many families miss, and there's no fix once the birthday passes without a filed application.

Special cases: grandchildren and other family members

Some profiles have their own paths worth knowing:

• Grandchildren of Spaniards: the Democratic Memory Law of 2022 enabled a special path for grandchildren of Spaniards who lost their nationality due to exile, persecution, or causes linked to the Franco regime. The original window had variable extensions and the criteria keep changing. For the current deadline at the moment you're reading this, check directly with the Ministry of Justice at mjusticia.gob.es or ask at the corresponding consulate. Don't trust old blog information because it has changed several times.
• Great-grandchildren: the law only covered up to grandchildren. If you're a great-grandchild of a Spaniard, you don't have a special path by origin and you have to follow the normal residency procedure.
• Domestic partnership (pareja de hecho): does NOT grant nationality by reduced residency, no matter how much the registered partnership gives you other rights in Spain. Only formal marriage opens the 1-year path. If this applies to you, consider getting married and starting the count from the wedding date.
• Parents of a Spaniard: if your father or mother was a Spaniard of origin but you didn't get nationality at birth (for example, because you were born abroad and your parents didn't register you in time), you can opt for Spanish nationality of origin. It's not residency; it's a different procedure handled at the Civil Registry or at the consulate of the country where you live.

Each of these cases has its own nuances and the documentation changes quite a bit. If your situation fits any of these, get informed at the Civil Registry or the consulate before starting to gather papers, because the requirements aren't the same as the general procedure and a wrong start wastes months.

How to start: paperwork and order

When an entire family wants to move at the same time, the order matters. A reasonable strategy is this:

• Minor children first. The sooner you file the option, the sooner you close it. Civil Registries take time, so it's better to get the file in as soon as possible. If you have several minor children, file one by one with their complete documents to avoid mixing files.
• Spouse in parallel. If your spouse has already been married and registered in the padrón with you in Spain for 1 year, their file can run in parallel with the children's. What takes the longest is the CCSE, which requires sign-up, exam, and certificate. Start there to avoid losing months waiting for a date.
• Adult children separately. Each one handles their own file from scratch, with their own certificates and timeframes. Pass them this guide and the related ones so they understand their path is different from their younger siblings'.
• Other family members case by case. For grandchildren, great-grandchildren, domestic partners considering marriage, or international shared custody situations, it's worth talking to an immigration lawyer before investing time in documentation that might not be useful.

A practical detail: many family procedures get stuck on certificates issued abroad (births, marriages) that need the Hague Apostille and sworn translation by a translator recognized by the Ministry of Foreign Affairs. Those certificates expire every 3 months for official use, so request them when you almost have the full file ready. Requesting them at the start and letting them sit for 8 months is a frequent mistake that forces you to restart the apostille and translation circle from zero.

Another point worth anticipating: Civil Registries work by appointment and availability varies widely between municipalities. In Madrid, Barcelona, or Valencia, appointments run out fast and sometimes you have to wait weeks just to submit documentation. If you live in a big city, book the appointment as soon as you start gathering papers, not when you already have them all. Moving several family procedures in parallel means several appointments, and each one has its own timing.

If your family situation is complex (previous marriages with children from another partner, shared custody with a foreign parent, children born in different countries), get legal advice before starting. Paying 200 euros for an hour with an immigration lawyer can save you months of returned papers. Each atypical case is solved with specific documentation, and improvising usually costs a lot of time.
