Spanish Nationality by Residence: Requirements and Process

Spanish nationality by residence allows foreign nationals to acquire Spanish citizenship after living in Spain legally, continuously and immediately before the application for the period required in each case. In addition to meeting the residence period, applicants must demonstrate good civic conduct and a sufficient degree of integration into Spanish society.

The general qualifying period is ten years, although it may be reduced to five, two or one year depending on the applicant’s personal circumstances and nationality of origin. Completing the required period does not automatically guarantee approval. The continuity of residence, criminal record, foreign documents, integration tests and any circumstance that may affect the application must also be reviewed.

This guide explains who can apply for Spanish nationality by residence, which qualifying period applies, which documents are usually required, how the application is submitted and which steps must be completed after a favourable decision.

What is Spanish nationality by residence?

Spanish nationality by residence is a route through which foreign nationals may acquire Spanish citizenship after residing legally in Spain for a specified period.

The residence required for nationality must not be confused with tax residence, municipal registration or a short-term stay. For this procedure, the key issue is legal residence under Spanish immigration law and whether that residence has been continuous and immediately prior to the application.

The authorities assess the application as a whole. Before filing, it is therefore important to review not only the dates of residence permits, but also renewals, travel outside Spain, criminal records, documents issued abroad and relevant family circumstances.

Applicants who are still reviewing their immigration status may find our English guide on the difference between an NIE and a residence permit in Spain useful.

How many years of residence are required?

The qualifying period depends on the applicant’s circumstances.

The one-year period may apply, among other situations, to a person born in Spanish territory; a person who did not exercise the right to opt for Spanish nationality within the relevant period; a person who has been legally subject to guardianship, foster care or another qualifying protective arrangement involving a Spanish person or institution; a person who has been married to a Spanish citizen for one year and is not legally or de facto separated; a widow or widower of a Spanish citizen where there was no separation at the time of death; or a person born outside Spain to a parent or grandparent who was originally Spanish.

Each reduced-period category has its own conditions and documentary requirements. The applicable period should not be selected solely because the applicant has a family connection with Spain or was born in Spain.

Legal and continuous residence immediately before the application

Residence must satisfy all three of the following conditions:

• Legal: it must be based on an authorisation or status recognised under Spanish immigration law.
• Continuous: it must be maintained throughout the required period without interruptions that are incompatible with the requirement.
• Immediately prior: the qualifying period must directly precede the date on which the application is filed.

Municipal registration proves an administrative address, but it does not by itself prove legal residence. Similarly, not every period of physical presence in Spain counts towards nationality.

Before filing, the full sequence of permits, renewals and residence cards should be reviewed together with periods spent outside Spain. Absences are assessed according to their duration, frequency, purpose and effect on the applicant’s genuine connection with Spain. A single simplified rule should not be applied without considering the facts of the individual case.

If legal residence is based on a non-lucrative permit, our English article on the benefits of non-lucrative residence in Spain provides additional context.

Good civic conduct

Applicants must demonstrate good civic conduct. This requirement is broader than simply providing criminal record certificates with no entries.

The authorities may consider criminal and police records, pending proceedings, cancelled records, administrative penalties and the applicant’s conduct during residence in Spain. The existence of an incident does not automatically determine the outcome, but it does require careful review and appropriate evidence.

Where records exist, applicants should confirm their current status, whether cancellation is available and how the circumstances may affect the application. Filing without this review may lead to requests for further information or an unfavourable decision.

Integration into Spanish society

Where required, integration is mainly demonstrated through tests administered by the Instituto Cervantes:

• CCSE: the test of constitutional and sociocultural knowledge of Spain.
• DELE A2 or higher: evidence of Spanish-language ability for applicants who must take the language test.

Some applicants are exempt from the DELE because of their nationality of origin. There are also situations in which a waiver or adapted testing arrangements may be available. These possibilities must be assessed under the applicable rules and the applicant’s individual circumstances.

Existing diplomas and certificates should also be checked to confirm that they are valid for the nationality procedure.

Who can submit the application?

An adult or emancipated applicant may start the procedure personally. In other cases, the application may need to be submitted by a legal representative or by the applicant with the legally required assistance, depending on age and legal circumstances.

Applications involving minors or people who require support measures need a specific review of representation, family documents and any authorisations that may be required.

An applicant may also act through a representative. Professionals who are legally required to belong to a professional association must communicate electronically with the Spanish Ministry of Justice in accordance with the rules governing the procedure.

Documents normally required

The exact documentation depends on the applicant’s circumstances. A standard application may include:

• The official application form.
• A complete and valid passport.
• The Foreigner Identity Card or equivalent document.
• A birth certificate issued by the country of origin.
• A criminal record certificate issued by the country of origin.
• Proof of payment of the administrative fee.
• Instituto Cervantes diplomas or certificates, where required.
• Documents proving the reduced qualifying period being claimed.
• Proof of representation, where applicable.

Depending on the case, marriage certificates, birth certificates of Spanish relatives, evidence of refugee status, cohabitation records, municipal registration certificates or other documents may also be required.

Foreign documents must satisfy the applicable legalisation or apostille requirements. Documents not issued in Spanish must be accompanied by the corresponding translation. Before filing, applicants should verify the validity of each document and ensure that names, surnames, dates and places are consistent throughout the application.

How to apply for Spanish nationality by residence

The nationality-by-residence procedure is administrative and is designed to be handled electronically. Applications may be submitted through the electronic office of the Spanish Ministry of Justice, without prejudice to any other legally available submission methods.

Online filing allows applicants to upload digitised documents, provide evidence of payment of the fee and obtain proof of registration. Where a representative files the application, evidence of that representation must be included.

Before submitting the application, we recommend:

1. Confirming the applicable residence period.
2. Reviewing all residence permits, renewals and absences.
3. Checking criminal records and any available cancellation.
4. Confirming the CCSE and DELE requirements.
5. Updating, legalising or apostilling foreign documents.
6. Checking that personal details are consistent.
7. Keeping a complete copy of the application.
8. Saving the proof of submission.

Monitoring the application and responding to requests

After filing, applicants should monitor notifications and the status of the procedure. The authorities may request additional documents, explanations or the correction of deficiencies.

A request for further information must be answered within the stated deadline and in a manner that is consistent with the original application. Providing additional documents without explaining a discrepancy may not resolve the issue raised by the authorities.

Contact and notification details should also be kept up to date. A change of address or a problem with an electronic certificate does not remove the obligation to monitor and respond to official communications.

How long does Spanish nationality by residence take?

The procedural rules establish a one-year period for issuing and notifying a decision. In practice, the actual duration may vary depending on the authorities’ workload, the complexity of the case, the reports required and whether further information is requested.

A complete application can reduce the risk of delays caused by errors or missing documents, but it cannot guarantee a specific decision date.

If the statutory period passes without a decision, the current status of the application and the available administrative or judicial options should be assessed before action is taken.

What to do if the application is refused

An unfavourable decision should be reviewed against the reasons given and the evidence included in the application. Refusals may relate to the residence calculation, civic conduct, integration, absences or documentary deficiencies.

Before challenging the decision, applicants should check:

• The date of notification.
• The precise reason for refusal.
• The evidence already included in the file.
• The applicable appeal deadlines.
• Whether an appeal or a new application is the better option.

Not every refusal should be handled in the same way. The appropriate strategy depends on whether the issue can be corrected, whether the authorities have made an assessment error or whether an essential requirement was missing.

What happens after approval?

A favourable decision does not complete the process by itself. The applicant must complete the oath or promise and any other post-approval requirements within the applicable period.

The acquisition is then registered with the Civil Registry, after which the applicant may request the corresponding Spanish identity documents. Personal information may also need to be updated with public authorities, banks, employers and other organisations.

In some cases, the applicant must declare the renunciation of their previous nationality, subject to the exceptions recognised by Spanish law. Whether the original nationality is effectively retained also depends on the law of the country of origin, so both legal systems should be checked.
