Does obtaining a second citizenship mean losing Spanish nationality?
Not automatically in every case. Under article 24 of the Spanish Civil Code, loss may occur in specific situations involving an emancipated Spanish citizen habitually resident abroad who voluntarily acquires another nationality or exclusively uses a nationality acquired before emancipation. A declaration to retain Spanish citizenship within the applicable three-year period may prevent loss. The rules for Spanish nationals of origin and the listed Ibero-American nationalities, Andorra, the Philippines, Equatorial Guinea or Portugal require separate attention. International nationality agreements can also matter.
We assess whether the person was Spanish by origin or acquisition, their dates of birth and naturalisation, residence abroad, possession and use of nationality, Civil Registry entries and any retention statement. A second passport alone does not settle the question.
Legal causes of loss and nullity to examine
- Voluntary acquisition abroad: certain acquisitions of a foreign citizenship by emancipated Spanish nationals habitually resident outside Spain, after the period established by article 24(1).
- Exclusive use of another nationality: where the relevant nationality was attributed before emancipation and the article 24(1) conditions apply.
- Children of Spanish parents born abroad: article 24(3) imposes a particular retention declaration in qualifying second-generation cases, generally within three years of majority or emancipation.
- Express renunciation: under article 24(2), when the Spanish national is emancipated, habitually resident abroad and holds another nationality.
- Non-origin nationals: article 25(1) covers certain cases of exclusive use of a previously renounced nationality, and specified foreign military or political service against an express government prohibition.
- Nullity for fraud: article 25(2) concerns a final judicial declaration of falsehood, concealment or fraud in the acquisition of nationality. It is legally distinct from ordinary loss.
The date of the events may require historical legislation and any applicable treaty to be examined; no automatic conclusion should be drawn from a generic checklist.
How ILS Tenerife can assist your case
- Case diagnosis: review the Civil Registry certificate, foreign naturalisation record, dates, residence and evidence of use of nationality.
- Retention: establish whether a timely declaration of conservation is available and identify the correct Civil Registry or Spanish consulate.
- Adverse decisions: examine the complete notification, the grounds of the entry or decision, evidence and available legal remedies.
- Appeal and litigation strategy: where legally appropriate, prepare a Civil Registry appeal and assess subsequent court proceedings and required representation.
- Recovery: assess article 26 requirements, including the exception to legal residence in Spain for emigrants and children of emigrants, and whether prior government authorisation is needed.
We define the precise scope, fees and any third-party expenses in an engagement agreement. A successful outcome cannot be guaranteed.
Received a notice that you lost citizenship? Protect your deadline
The appeal process depends on the authority and type of decision. Under articles 85–87 of Civil Registry Law 20/2011, certain Civil Registry officers' decisions may be appealed to the Directorate-General for Legal Security and Public Faith; the statutory period under article 85 is one month. Other acts, nationality-by-residence refusals and subsequent judicial actions may follow different rules. Do not assume a general deadline without analysing the decision and date of notification.
For a first review, prepare your Spanish birth certificate, Civil Registry nationality records, Spanish identity documents if held, foreign citizenship documentation, evidence of habitual residence, any retention statement, and the decision with proof of service. Please do not send sensitive passport files through an unsecured contact form.
Common questions
Did I lose Spanish nationality when I became British, Canadian or American?
Not necessarily. The answer depends on the relevant Civil Code provisions, origin status, habitual residence, nationality acquired, dates and declarations.
Can citizenship be recovered from outside Spain?
Article 26 sets a general legal-residence rule but exempts emigrants and their children. A declaration and Civil Registry registration are also required; some cases need government authorisation.
Can I appeal a consular Civil Registry decision?
Some consular Civil Registry decisions can be appealed under the applicable Civil Registry legislation. We must examine the decision and its notification before identifying the remedy.
