Can You Get Spanish Citizenship After One Year with a Spanish Partner?

If you are in a relationship with a Spanish citizen and have registered as a pareja de hecho, or domestic partnership, you may be wondering whether you can apply for Spanish citizenship after just one year.

This is one of the most common questions among foreign nationals living in Spain with their Spanish partners.

The answer depends on an important legal distinction: being in a registered domestic partnership with a Spanish citizen is not the same as being married to a Spanish citizen when it comes to acquiring Spanish nationality.

Under Spanish law, certain foreign nationals married to Spanish citizens can apply for Spanish citizenship after just one year of legal residence. However, this reduced period does not automatically apply to unmarried couples, even if their relationship is officially registered.

Nevertheless, establishing a domestic partnership can provide significant immigration benefits, particularly when applying for residence in Spain.

In this comprehensive guide, Visal Immigration Lawyers explains the differences between domestic partnerships and marriage, how to qualify for Spanish citizenship after one year, when your residence period starts counting, and the most practical options available in 2026.

What Does Spanish Law Say About Citizenship After One Year?

The starting point is Article 22 of the Spanish Civil Code, which establishes the legal residence periods required to obtain Spanish citizenship.

As a general rule, foreign nationals must complete ten years of legal, continuous residence in Spain immediately before submitting their citizenship application.

However, the legislation establishes several important exceptions.

Nationals by origin of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea and Portugal, as well as persons of Sephardic origin, may qualify after two years of legal residence.

Recognized refugees may qualify after five years.

Certain applicants benefit from a particularly favorable requirement: only one year of legal residence.

One of these situations concerns foreigners married to Spanish citizens.

Article 22.2(d) of the Spanish Civil Code establishes that one year of residence is sufficient when, at the time of the application, the foreign national has been married to a Spanish citizen for at least one year and is not legally or de facto separated.

This provision is the legal basis for what is commonly described as Spanish citizenship by marriage.

However, two fundamental points must be understood.

First, marrying a Spanish citizen does not automatically grant Spanish nationality.

Second, the legislation specifically refers to marriage. It does not extend this particular benefit to registered unmarried partnerships.

Therefore, if you are in a pareja de hecho with a Spanish citizen, you cannot automatically qualify for the one-year citizenship rule solely because of that relationship.

If you are uncertain about which residence period applies to your circumstances, schedule your consultation here with one of our immigration lawyers.

Is a Pareja de Hecho the Same as Marriage for Spanish Citizenship?

No. Although marriage and registered domestic partnerships may produce similar legal consequences in certain areas of Spanish immigration law, they do not provide identical rights when applying for Spanish citizenship.

This distinction is particularly important for foreign nationals who have lived with their Spanish partners for several years.

Imagine an American citizen who has lived with her Spanish boyfriend in Barcelona since 2022.

The couple registered their domestic partnership in Catalonia in 2023.

They share a home, maintain a stable relationship and have lived together continuously.

Although their relationship is genuine and officially registered, the foreign partner cannot rely on the one-year citizenship requirement established for spouses of Spanish citizens.

The reason is straightforward: Article 22.2(d) of the Spanish Civil Code refers specifically to marriage.

It does not establish a general equivalence between marriage and unmarried partnerships for this purpose.

There is also no rule allowing several years spent in a domestic partnership to be converted retroactively into years of marriage.

Consequently, a foreign national may have been registered as the domestic partner of a Spanish citizen for five years without becoming eligible for the one-year nationality provision.

However, they may qualify for citizenship through another residence period, depending on their nationality, immigration history and personal circumstances.

This is why a complete assessment of the applicant's situation is essential before determining when an application can be submitted.

What Are the Immigration Benefits of a Domestic Partnership with a Spanish Citizen?

Although a pareja de hecho does not automatically reduce the citizenship residence requirement to one year, it can offer very important advantages in obtaining legal residence in Spain.

Since 20 May 2025, Spain has applied a new Immigration Regulation approved through Royal Decree 1155/2024.

This regulation introduced a specific residence authorization for qualifying family members of Spanish citizens.

Among the eligible family members are foreign nationals who are registered partners of Spanish citizens, as well as certain unmarried partners who can demonstrate a sufficiently stable relationship.

As a result, foreign nationals in genuine relationships with Spanish citizens may be able to obtain Spanish residence without getting married.

Residence Through a Registered Domestic Partnership

Article 94 of the Immigration Regulation includes foreign partners who have registered a relationship equivalent to marriage in a qualifying public registry.

For example, a foreign national living with their Spanish partner in Barcelona may qualify for residence if their relationship has been properly registered and the remaining legal requirements are met.

The authorities will examine the existence of the relationship and the documentation supporting the application.

The residence authorization for family members of Spanish citizens is generally valid for five years and permits employment and self-employment in Spain under the applicable legal conditions.

This can be particularly advantageous for couples who wish to establish a long-term life together in Spain.

Can You Apply Without Registering as a Pareja de Hecho?

Yes, in certain circumstances.

The Immigration Regulation also recognizes stable unmarried relationships that have not been formally registered.

As a general rule, the couple must demonstrate a relationship involving at least twelve continuous months of cohabitation comparable to marriage.

However, this minimum period of previous cohabitation is not required where the couple has children together, provided the relationship continues.

The existence and stability of the relationship must be properly documented.

Therefore, formal registration is not necessarily the only option for couples seeking residence based on their relationship with a Spanish citizen.

The appropriate procedure depends on the couple's circumstances.

Nevertheless, obtaining residence through an unregistered stable relationship does not automatically entitle the applicant to Spanish citizenship after one year.

The legal distinction between residence rights and citizenship requirements remains essential.

When Does the Residence Period for Spanish Citizenship Start Counting?

One of the most important questions in any Spanish nationality application concerns the date from which the required residence period begins.

Spanish citizenship by residence requires legal, continuous residence immediately preceding the application.

Simply living physically in Spain for one, two or ten years is not enough.

The applicant must demonstrate a qualifying period of legal residence.

For example, someone who has lived in Barcelona for three years but obtained their first residence authorization only six months ago cannot automatically assume that all three years count towards citizenship.

Registration at the town hall, commonly called empadronamiento, may provide evidence of where someone lives.

However, it is not equivalent to holding legal residence status.

Similarly, periods spent in Spain under a student stay authorization should not automatically be treated as qualifying residence for citizenship purposes.

The precise immigration history must be examined.

Does Residence Obtained Through a Domestic Partnership Count?

Yes.

When a foreign national obtains a qualifying residence authorization as the family member of a Spanish citizen, the period of legal residence under that authorization can count towards the citizenship residence requirement.

This is one of the most significant benefits of obtaining residence through a pareja de hecho.

For example, imagine an Argentine citizen by origin who obtains a residence authorization because he is the registered partner of a Spanish woman.

As a national by origin of an Ibero-American country, he may qualify for Spanish citizenship after two years of legal, continuous residence, provided he meets the remaining requirements.

He does not need to marry his Spanish partner to benefit from that two-year period.

By contrast, an American citizen who receives the same residence authorization through a domestic partnership cannot automatically qualify for citizenship after one year.

Unless another statutory exception applies, the ordinary ten-year residence requirement will remain relevant.

Therefore, a domestic partnership can help you establish legal residence in Spain, but it does not independently shorten the citizenship residence requirement to one year.

What Happens If You Register as a Domestic Partnership and Later Get Married?

This is one of the most interesting situations for international couples.

Imagine a couple consisting of a Spanish citizen and an American citizen.

They have lived together for several years and are officially registered as domestic partners.

The American citizen obtains Spanish residence through the relationship and begins accumulating qualifying legal residence.

Later, the couple decides to marry.

Can the American citizen then benefit from the one-year citizenship requirement?

Yes, provided both the marriage and residence requirements are satisfied.

Specifically, the applicant must have completed at least one year of legal, continuous residence immediately before applying.

They must also have been married to the Spanish citizen for at least one year when submitting the application, without legal or de facto separation.

These are two separate requirements.

The first concerns the duration and continuity of legal residence.

The second concerns how long the marriage has existed.

Importantly, the entire period of legal residence does not necessarily need to have been obtained under a residence authorization specifically based on marriage.

For example, a foreign national who has already legally resided in Spain for three years and subsequently marries a Spanish citizen may qualify for the reduced period once one year of marriage has elapsed, provided all other conditions are met.

Similarly, someone who first obtained residence through a domestic partnership may be able to rely on that earlier period of legal residence after marrying.

However, the years spent as domestic partners cannot be treated as years of marriage.

If you are considering marriage and want to establish the earliest legally possible date for applying for Spanish citizenship, schedule your consultation here.

Spanish Citizenship Through Domestic Partnership or Marriage: Three Examples

The differences become easier to understand through practical situations.

Example 1: An Unmarried American Partner

An American citizen obtains her first Spanish residence authorization on 1 January 2026 through her registered domestic partnership with a Spanish citizen.

Throughout 2026, the couple continues living together.

On 1 January 2027, she completes one year of legal residence in Spain.

Can she apply for Spanish citizenship because she has lived with her Spanish partner for one year?

Not on that basis.

Although she has completed one year of legal residence, she has not satisfied the legal requirement of being married to a Spanish citizen for at least one year.

Unless another exception applies, she will be subject to the ordinary residence period applicable to her circumstances.

Example 2: A British Citizen Who Later Marries

A British citizen obtains legal residence in Spain on 1 February 2026 as the registered partner of a Spanish national.

The couple marries on 1 June 2026.

On 1 June 2027, the British citizen will have completed one year of marriage and more than one year of legal residence.

Provided the residence has remained continuous and the other legal requirements are satisfied, the applicant may be eligible to apply under the reduced one-year provision.

The marriage must be legally valid, the couple must not be separated, and the remaining nationality requirements must be met.

Example 3: A Colombian Citizen in a Domestic Partnership

A Colombian citizen by origin obtains legal residence in Spain on 1 March 2026 because she is the registered partner of a Spanish citizen.

They decide to remain unmarried.

Assuming the residence is continuous and all other legal requirements are fulfilled, she may become eligible to apply for Spanish citizenship after completing two years of legal residence, on 1 March 2028.

In this situation, the reduced residence period results from her Colombian nationality by origin, not her domestic partnership.

These examples demonstrate why nationality, residence history and relationship status must be considered together.

Requirements for Spanish Citizenship After One Year of Marriage

Marrying a Spanish citizen is not enough to acquire Spanish nationality automatically.

Applicants must satisfy the general requirements established by the Spanish Civil Code in addition to the reduced residence and marriage periods.

Legal and Continuous Residence

The applicant must demonstrate at least one year of legal, continuous residence in Spain immediately preceding the application.

Extended periods outside Spain can create difficulties when assessing whether the residence requirement has been satisfied.

However, not every trip abroad automatically interrupts qualifying residence.

The duration, frequency and circumstances of absences should be evaluated carefully.

A Valid Marriage to a Spanish Citizen

At the time of applying, the foreign national must have been married to a Spanish citizen for at least one year.

The couple must not be legally separated or separated in practice.

Evidence of continued cohabitation may therefore be particularly important.

Applicants relying on this reduced residence period must provide documentation establishing their marriage to the Spanish citizen.

This normally includes a Spanish Civil Registry marriage certificate and evidence concerning the couple's shared residence.

Good Civic Conduct

Article 22.4 of the Civil Code requires applicants to demonstrate good civic conduct.

The authorities may consider criminal records and other relevant circumstances when evaluating this requirement.

It is important not to confuse police records with criminal convictions.

Similarly, not every administrative issue automatically leads to refusal.

Each situation must be assessed individually under the applicable legal standards.

Integration into Spanish Society

Applicants must also demonstrate a sufficient degree of integration into Spanish society.

This is normally assessed through official examinations administered by the Instituto Cervantes, although statutory exemptions and dispensations may apply.

Being married to a Spanish citizen does not automatically exempt someone from these requirements.

If you would like to determine whether you satisfy the requirements for nationality by marriage, schedule your consultation here.

What Documents Are Required for Spanish Citizenship by Marriage?

Preparing the documentation correctly is essential to avoid unnecessary requests for additional information and delays.

The exact documents depend on the applicant's nationality, age and individual circumstances.

Generally, a foreign national applying for Spanish citizenship by residence under the reduced period for spouses should prepare the following:

• Valid passport and documentation establishing legal residence in Spain.

• Birth certificate, appropriately apostilled or legalized and translated where required.

• Criminal record certificate from the country of origin and any other certificates required by the applicable rules.

• Spanish birth certificate of the Spanish spouse.

• Marriage certificate issued by the Spanish Civil Registry.

• Evidence of joint residence or cohabitation.

• Proof of passing the applicable nationality examinations, unless an exemption or dispensation applies.

• Proof of payment of the relevant administrative fee.

Foreign documents must satisfy the applicable formal requirements.

For example, certain certificates require an apostille under the Hague Convention or diplomatic legalization.

Documents issued in languages other than Spanish may also require an official sworn translation.

Some certificates have validity requirements that must be checked before submission.

A particularly important situation arises when the couple married abroad and the marriage has not yet been registered with the Spanish Civil Registry.

Where the applicant intends to rely on marriage to a Spanish citizen, the validity and appropriate registration of the marriage should be reviewed before submitting the nationality application.

Careful preparation helps reduce the risk of administrative requests and avoidable delays.

Do You Have to Pass the CCSE and DELE A2 Exams?

Most adult applicants for Spanish citizenship by residence must demonstrate knowledge of the Spanish language and Spanish constitutional and sociocultural matters.

There are two principal examinations administered by the Instituto Cervantes.

The CCSE Exam

The CCSE examination assesses knowledge of the Spanish Constitution, public institutions, culture and society.

It is generally required for adult citizenship applicants, subject to the exemptions and dispensations established by law.

Marriage to a Spanish citizen does not automatically exempt the applicant from taking it.

The DELE A2 Spanish Language Exam

The DELE A2 examination demonstrates a basic level of Spanish language proficiency.

However, nationals by origin of certain Spanish-speaking countries or territories are exempt from taking this language examination.

For example, a Colombian citizen by origin applying for Spanish citizenship will normally be exempt from the DELE A2 requirement.

By contrast, an American citizen who does not qualify for an exemption will generally need to demonstrate the required language level.

Additional exemptions or dispensations may apply depending on personal and educational circumstances.

It is advisable to check these conditions before registering for either examination.

How Do You Apply for Spanish Citizenship?

Once the required residence period and all other legal conditions have been satisfied, the applicant may begin the Spanish citizenship by residence procedure.

Applications are processed by the Spanish Ministry of Justice.

The electronic application system allows applicants or authorized representatives to submit the required information and documentation.

The procedure is available through the official Spanish Ministry of Justice website.

It is important to identify the correct legal basis for the application and demonstrate eligibility for any reduced residence period being claimed.

The Ministry may subsequently request additional documentation.

Any such requests should be answered within the applicable deadline.

Submitting an application before satisfying the minimum legal requirements may result in refusal.

For that reason, applicants should not calculate eligibility solely from the date of their domestic partnership registration or municipal address registration.

The relevant dates include the beginning of qualifying legal residence, the date of marriage and the continuity of the required conditions.

How Long Does Spanish Citizenship Actually Take?

It is essential to distinguish between the minimum residence period required before applying for citizenship and the amount of time the government takes to process the application.

When discussing Spanish citizenship after one year through marriage, we are referring to the reduced period of legal residence required to become eligible to apply.

We are not promising that an applicant will receive a Spanish passport within twelve months.

After submission, the Ministry of Justice must examine the documents, verify that the legal requirements are satisfied and issue the relevant decision.

The regulations establish a one-year period for processing and notifying a decision on citizenship by residence applications.

However, if the Administration does not issue a decision within that period, the application is deemed rejected by administrative silence for procedural purposes, without removing the Administration's duty to issue an express decision.

Actual processing times can differ considerably between applications.

Furthermore, obtaining a favorable decision does not necessarily mean that all formalities have been completed.

The Spanish Citizenship Oath

Once citizenship has been granted, the applicant must complete the formalities established under Article 23 of the Spanish Civil Code.

Depending on the case, these include an oath or promise of loyalty to the King and obedience to the Constitution and Spanish laws.

The applicant may also need to make the legally required declaration concerning their previous nationality.

The applicable formalities must generally be completed within 180 days of notification of the citizenship grant.

Registration of the acquisition of Spanish nationality in the Civil Registry is also required.

Only after the relevant procedures have been completed can the new Spanish citizen obtain the corresponding Spanish identity documents.

Therefore, obtaining citizenship involves more than simply completing one year of residence or marriage.

What Happens If You Separate After Applying for Spanish Citizenship?

A couple's circumstances may change while the nationality application is being processed.

It is important to distinguish between separation before submitting the application and separation afterward.

Article 22.2(d) of the Civil Code expressly requires the applicant to have been married to a Spanish citizen for at least one year and not be legally or de facto separated at the time of the application.

If the couple was already separated when the application was submitted, the foreign national would not meet that specific requirement.

If separation occurs after submission, the legal consequences must be assessed according to the circumstances, relevant dates and documentation.

It would be inaccurate to suggest that every subsequent separation automatically prevents the applicant from obtaining Spanish citizenship.

The requirements for nationality must also be distinguished from the conditions governing residence authorization as the family member of a Spanish citizen.

These are different legal procedures.

A change in family circumstances may affect immigration residence rights even where a citizenship application has already been submitted.

If your relationship has changed while your application is pending, seek legal advice before taking steps that could affect your immigration position.

Common Mistakes When Applying for Citizenship Through a Domestic Partnership or Marriage

One of the most frequent mistakes is assuming that registering as a pareja de hecho automatically provides the same citizenship benefits as marriage.

As explained, Spanish nationality legislation does not establish that equivalence for the special one-year residence period.

Another mistake is calculating the required residence period from the date of municipal registration.

Legal residence and empadronamiento are different concepts and must be considered separately.

Some applicants also believe that marrying a Spanish citizen allows them to apply immediately, even if they have not completed sufficient legal residence.

Marriage alone does not grant Spanish nationality.

A further mistake is overlooking other reduced residence periods available under the Civil Code.

For example, an Argentine citizen by origin who has already completed two years of qualifying legal residence may be able to apply without marrying their Spanish partner.

Finally, applications are sometimes submitted with expired certificates, improperly legalized documents or incorrect translations.

These issues can lead to additional documentation requests and longer processing times.

At Visal Immigration Lawyers, we recommend reviewing the applicant's complete immigration history before preparing a nationality application, especially where different residence permits have been held over time.

Frequently Asked Questions About Spanish Citizenship and Domestic Partnerships

1. Can I Apply for Spanish Citizenship After One Year as a Registered Domestic Partner?

No, not solely because you are the registered domestic partner of a Spanish citizen. Article 22.2(d) of the Civil Code reserves the relevant one-year residence period for qualifying spouses. However, you may benefit from another reduced residence period depending on your nationality, immigration history or other legally recognized circumstances.

2. If I Marry My Spanish Partner, Can I Apply for Citizenship Immediately?

Not necessarily. You must have been married to a Spanish citizen for at least one year when applying and have completed at least one year of legal, continuous residence immediately beforehand. Residence accumulated before marriage can count towards the residence requirement, provided the other legal conditions are satisfied.

3. Does My Previous Residence as a Domestic Partner Count After Marriage?

Yes. Qualifying legal residence obtained through a domestic partnership can count towards a later citizenship application. If you subsequently marry your Spanish partner, you do not necessarily start the residence calculation again. However, you must still complete one year of marriage to qualify for the special spousal residence period.

4. Can I Apply for Spanish Citizenship if I Am Colombian and Have a Spanish Domestic Partner?

Yes, provided you meet the applicable conditions. Colombian nationals by origin may qualify for Spanish citizenship after two years of legal, continuous residence. Marriage is not required to benefit from that particular reduction. A registered domestic partnership may help you obtain qualifying residence, but it does not itself reduce the requirement.

5. Can I Obtain Spanish Citizenship After One Year Because My Child Is Spanish?

Not automatically. Being the parent of a Spanish citizen may provide a route to obtaining legal residence in Spain, subject to the applicable requirements. However, having a Spanish child does not independently establish a one-year citizenship residence period. Your nationality, legal residence history and other circumstances must be evaluated.

Should You Marry Your Spanish Partner to Obtain Citizenship Faster?

The appropriate answer depends on your immigration situation and personal circumstances.

If you do not yet hold legal residence in Spain, obtaining a residence authorization as the partner of a Spanish citizen may be an important first step.

If you already hold residence, the priority should be determining how much qualifying legal residence you have accumulated and which citizenship period applies to you.

If you are registered as domestic partners and are considering marriage, understanding the legal consequences of that decision can help you plan your nationality application.

However, marriage is not necessary for every foreign national who wishes to acquire Spanish citizenship within a relatively short period.

For instance, nationals by origin of Ibero-American countries can benefit from the two-year rule whether they are married, unmarried or registered domestic partners.

Other foreign nationals may face the ordinary ten-year residence requirement if they remain unmarried and no other statutory exception applies.

Marriage to a Spanish citizen may establish a much shorter route to eligibility, but only when the relationship and the applicant's circumstances satisfy the relevant legal requirements.

The objective should not simply be to submit a citizenship application as soon as possible. It should be to apply when all the conditions are met and the application has a sound legal basis.
