How Is Turkish Citizenship Acquired Through Marriage?

Marrying a Turkish citizen does not, by itself, confer Turkish citizenship on the foreign spouse. Article 16 of Law No. 5901 on Turkish Citizenship (5901 sayılı Türk Vatandaşlığı Kanunu) provides as follows:

"ARTICLE 16 – (1) Marriage to a Turkish citizen does not directly confer Turkish citizenship. However, a foreigner who has been married to a Turkish citizen for at least three years and whose marriage continues may apply to acquire Turkish citizenship. Applicants must: a) live within a family union (aile birliği içinde yaşama), b) not engage in any activity incompatible with the marital union, c) have no condition that would constitute an impediment on grounds of national security or public order. (2) Where the marital union ends after the application due to the death of the Turkish citizen spouse, the condition in subparagraph (a) of the first paragraph shall not be required. (3) A foreigner who has acquired Turkish citizenship through marriage shall retain Turkish citizenship, provided they acted in good faith at the time of marriage, if the marriage is later annulled (butlan)." (Law No. 5901, Art. 16)

As is apparent from the text, once the required duration and conditions are jointly satisfied, the marriage merely gives rise to a right to apply; the actual acquisition of citizenship remains subject to a separate administrative review and discretionary decision. This article examines the legal framework governing acquisition of citizenship through marriage on the basis of Law No. 5901 (dated 29 May 2009) and the Regulation on the Implementation of the Turkish Citizenship Law (Türk Vatandaşlığı Kanununun Uygulanmasına İlişkin Yönetmelik), enacted by Council of Ministers Decision No. 2010/139 dated 11 February 2010, together with the effect of divorce, death, and a declaration of absence (gaiplik) on the application process.

Quick Reference

I. Legal Basis

The principal legal basis is Law No. 5901 on Turkish Citizenship, published in the Official Gazette dated 12 June 2009, No. 27256. The procedures and principles for its implementation are set out in the Regulation on the Implementation of the Turkish Citizenship Law, adopted by Council of Ministers Decision No. 2010/139 dated 11 February 2010 and published in the Official Gazette dated 6 April 2010, No. 27544. Article 14(1)(ç) of the Regulation lists acquisition of citizenship through marriage as a distinct category of acquisition by decision of the competent authority.

Article 10(1) of Law No. 5901 further provides:

"A foreigner who wishes to acquire Turkish citizenship may acquire it by decision of the competent authority if they satisfy the conditions specified in this Law. However, satisfying the required conditions does not confer an absolute right to the person to acquire citizenship." (Law No. 5901, Art. 10/1)

This provision confirms that even where all the conditions discussed below are met, the applicant is not thereby granted a guaranteed entitlement; the matter remains subject to the discretion of the Ministry of Interior (the "Ministry").

II. Conditions for the Right to Apply

Under Article 16(1) of Law No. 5901, quoted in full above, four elements must be jointly satisfied for the right to apply to arise: (i) marriage to a Turkish citizen for at least three years, (ii) the continued subsistence of that marriage, (iii) living within a family union, and (iv) the absence of any activity incompatible with the marital union or any condition constituting an impediment on grounds of national security or public order.

Article 28 of the Regulation sets out the matters to be investigated by the provincial security directorate:

"The provincial directorate of security shall investigate, with respect to the foreigner seeking to acquire Turkish citizenship through marriage: a) whether they live within a family union; b) whether they have engaged in conduct incompatible with the marital union, such as prostitution or procuring; c) whether there exists any condition constituting an impediment on grounds of national security or public order to their acquisition of Turkish citizenship; the resulting positive or negative assessment shall be clearly recorded on the investigation form." (Regulation, Art. 28/1)

A particular point requiring attention in calculating the marriage duration arises where the spouse acquired Turkish citizenship only after the marriage. Under Article 25(3) of the Regulation, in such cases the three-year period runs from the date the spouse acquired Turkish citizenship, not from the date of marriage.

These conditions differ markedly from those governing acquisition of citizenship through the general route under Article 11 of Law No. 5901, which requires five years of uninterrupted residence in Turkey and adequate knowledge of Turkish; no such residence period or language requirement is prescribed for acquisition through marriage.

III. Grounds for Rejection of the Application

Article 25(2) of the Regulation expressly and exhaustively lists the circumstances in which an application will not be accepted:

"Where the investigation establishes that the foreigner: a) has not been married to a Turkish citizen for three years; b) the marriage has ended prior to the application date for reasons such as divorce or death; c) is subject to ongoing criminal proceedings or is convicted or in pretrial detention; ç) has failed to produce the documents required under Article 26 — the application shall not be accepted, and the person concerned shall be duly notified." (Regulation, Art. 25/2)

This provision addresses one of the points most frequently overlooked in practice: where the marriage has ended through divorce prior to the application date, the application is rejected outright, irrespective of whether the three-year duration requirement has otherwise been met. In other words, even where the three-year period has elapsed, the application cannot be accepted if the marital union has, as a matter of law, already ended at the time of application.

IV. Effect of the Termination of the Marital Union on the Application: Death, Divorce, and Absence (Gaiplik)

1. Death of the Turkish Citizen Spouse

Under Article 16(2) of Law No. 5901, quoted above, where the marital union ends due to the death of the Turkish citizen spouse after the application has been filed, the family-union condition is not required. This exception applies only to deaths occurring after the application; a death occurring before the application date constitutes a ground for rejection under Article 25(2)(b) of the Regulation.

2. Divorce

Unlike death, neither the Law nor the Regulation provides any exception in favour of divorce. Under Article 25(2)(b) of the Regulation, a marriage that has ended through divorce prior to the application date results in rejection of the application. There is no separate provision in the Regulation addressing the possibility that a divorce occurs after the application is accepted but before a final decision is issued. However, given that Article 16(1) requires the marriage to "continue" as an ongoing condition, it is considered that a divorce occurring during the review process would likewise adversely affect the application.

3. Absence (Gaiplik)

Law No. 5901 and its Regulation do not separately address a declaration of absence (gaiplik) concerning the Turkish citizen spouse. Reference must therefore be made to the general provisions of the Turkish Civil Code (Türk Medenî Kanunu):

"The spouse of a person in respect of whom a declaration of absence has been made may not remarry unless the court has decreed the dissolution of the marriage (evliliğin feshi). The spouse of the missing person may seek dissolution of the marriage together with the application for a declaration of absence, or in a separate action." (Turkish Civil Code No. 4721, Art. 131)

The consequence of this provision is that, unlike death, a declaration of absence does not by itself and automatically terminate the marriage; the marriage ends only where the spouse separately obtains a court decree of dissolution. On this point, the following is generally accepted in legal doctrine:

• Where the declaration of absence is accompanied by a decree dissolving the marriage, the marriage is thereby legally terminated, and the right to apply is regarded as extinguished within the meaning of Regulation Article 25(2)(b).

• Where no decree of dissolution has been obtained and the marriage subsists on paper, the family-union condition may nonetheless be practically impossible to satisfy given that the whereabouts of the spouse are unknown; the administration retains broad discretion to reject the application on this ground.

• Some commentators argue that, given the legal consequences of a declaration of absence are analogous to death, an absence arising after the application should by analogy benefit from the death exception under Article 16(2); however, because the statutory text refers only to "death," this view is not the prevailing one, and no precedent has been identified confirming that administrative practice applies this exception by extension.

In sum, the effect of a declaration of absence on a citizenship application is not expressly resolved in the legislation; the source review conducted for this article did not identify a verifiable judicial decision addressing this specific point, with confirmed parties and reasoning. Accordingly, where such a situation arises in a specific case, it is recommended that confirmation be separately sought from the relevant governorate (valilik) and the General Directorate of Population and Citizenship Affairs of the Ministry of Interior before applying. It should further be noted that, for the purpose of determining the law applicable to a declaration of absence, Article 11 of Law No. 5718 on Private International and Procedural Law generally applies the person's national law, but permits a declaration of absence under Turkish law where the spouse is a Turkish citizen.

V. Application Procedure and Review Process

Article 26 of the Regulation sets out the documents required in the application file: a form petition stating the request, a civil registry record for the Turkish citizen spouse, the foreigner's passport or equivalent document showing nationality, a document evidencing identity, a valid residence permit if resident in Turkey, and any final court judgment, where applicable.

For applications filed domestically, the file is prepared by the provincial directorate and then forwarded to the provincial directorate of security for investigation (Art. 27). The commission stage has a distinct character for marriage-based applications:

"The foreigner seeking to acquire Turkish citizenship and their spouse shall be interviewed separately and jointly by the commission in order to establish whether the marriage is a genuine marriage or one entered into for the purpose of acquiring Turkish citizenship." (Regulation, Art. 29/1)

For applications filed abroad, the same assessment is carried out by the deputy consul responsible for consular affairs or a more senior official:

"The deputy consul responsible for consular affairs, or a more senior official, shall interview the foreign national and their spouse separately and jointly in order to determine whether the marriage is a genuine marriage or one entered into for the purpose of acquiring Turkish citizenship." (Regulation, Art. 30/2)

At the final stage of review, a further security assessment is carried out. Article 35(2) of the Regulation provides that, for applications made under Article 16 of the Law, an archive investigation shall be requested from the National Intelligence Organization (MİT) and the General Directorate of Security in order to determine whether any impediment exists on grounds of national security or public order. Applicants found to satisfy the required conditions may acquire Turkish citizenship by decision of the Ministry of Interior under Article 35(5).

Note: Various decisions of the 10th Chamber of the Council of State (Danıştay) have been found to hold that conduct incompatible with the marital union must relate to a period following the date of marriage, and that the family-union condition should not be interpreted narrowly or formalistically by the administration.

VI. Consequences of Annulment of the Marriage for Citizenship

Under Article 16(3) of Law No. 5901, quoted above, a foreigner who has acquired Turkish citizenship through marriage retains that citizenship, provided they acted in good faith at the time of marriage, if the marriage is subsequently annulled (butlan). Article 31 of the Regulation gives concrete effect to this principle:

"A person who has acquired Turkish citizenship through marriage shall lose Turkish citizenship if the marriage is annulled. However, a foreigner who acquired Turkish citizenship through marriage shall retain Turkish citizenship where the Ministry, following its review, determines that the person acted in good faith at the time of marriage. A child born of a marriage that is annulled shall retain Turkish citizenship regardless of whether either parent acted in good faith." (Regulation, Art. 31)

Annulment is a general institution of family law regulated under the Turkish Civil Code No. 4721. Article 145 provides that a marriage is subject to absolute nullity where, among other things, one of the spouses was already married at the time of marriage, permanently lacked capacity of discernment, suffered from a degree of mental illness precluding marriage, or the spouses were related within a degree that precludes marriage. Article 156 provides that, even in cases of absolute nullity, the marriage ends only by decision of a judge, and continues to produce all the effects of a valid marriage until that decision is rendered.

VII. Relationship Between the Citizenship Application and the Residence Permit

The foreign spouse's physical presence in Turkey is not required while the citizenship application is under review. However, for foreign spouses who intend to reside in Turkey, the family residence permit regulated under Article 34 of Law No. 6458 on Foreigners and International Protection separately becomes relevant. This permit is an administrative matter independent of the citizenship application; it should be particularly emphasised that the citizenship application process and the residence permit process must not be conflated, as frequently occurs in practice.

VIII. Conclusion and Assessment

Taken together, Article 16 of Law No. 5901 and Articles 25 to 31 of the Regulation show that acquisition of Turkish citizenship through marriage is an exceptional route, subject to distinctive procedures conditioned on a minimum duration, the family-union requirement, and a multifaceted review for sham marriage and security concerns. Under Article 10(1) of Law No. 5901, satisfying the required conditions does not, even then, confer an absolute right.

As discussed above, the legislation prescribes different consequences depending on whether the marriage ends through death, divorce, or a declaration of absence: divorce and death occurring before the application constitute grounds for rejection, death occurring after the application removes the family-union requirement, while absence remains an area of genuine uncertainty not expressly resolved in the legislation. Independent legal advice is recommended before filing any specific application, particularly where special circumstances of the marriage are present (the death of a spouse, divorce, absence, prior marriages, and the like).
