Abstract

One of the most important legal questions facing individuals who acquired Turkish citizenship through investment or other exceptional naturalisation procedures is whether their citizenship remains legally valid.

Following the criminal investigations and administrative reviews publicly announced in 2025 and 2026, many naturalised Turkish citizens living abroad have become concerned about their citizenship records, Turkish passports, national identity cards, family members’ legal status and ability to enter Türkiye.

However, purchasing property from a construction company under investigation, being mentioned in an investigative file or becoming subject to a review of investment eligibility does not necessarily mean that Turkish citizenship has been cancelled.

Conversely, continued access to the Turkish e-Government portal, the presence of population records or possession of a passport that has not reached its printed expiry date does not conclusively establish that no subsequent citizenship decision has been issued.

The correct legal inquiry must determine whether an administrative decision exists, which authority issued it, the statutory provision relied upon, the decision date, whether and how notification occurred, and how the decision was reflected in official records.

This article analyses the relevant provisions of Turkish Citizenship Law No. 5901, Administrative Judicial Procedure Law No. 2577, Council of State Law No. 2575 and Law No. 6458 on Foreigners and International Protection.

It also examines three significant Council of State decisions from 2025 and 2026 concerning the evidentiary grounds for withdrawal, irregular investment documentation and the consequences of missing a judicial filing deadline.

The discussion applies to people of all national origins who have acquired Turkish citizenship, including Arab, Chinese, Russian, Iranian, Afghan, European and other foreign-born Turkish citizens.

1. Do Reports About Turkish Citizenship Revocations Mean That Everyone Has Lost Citizenship?

Investigations concerning alleged irregularities in investment-based Turkish citizenship acquisitions attracted increasing public attention in 2025 and expanded during 2026.

On August 4, 2026, the Turkish Ministry of Justice announced that legal proceedings had been initiated concerning the cancellation of citizenship acquired by 687 individuals.

A second operation announced on September 21, 2026, involved the citizenship files of 1,070 people, comprising 263 principal investors and 807 family members.

These announcements demonstrate that extensive criminal and administrative investigations were underway. They do not establish that every person mentioned had already received a final individual administrative decision terminating citizenship.

1.1. Different Stages of Citizenship Review

The following legal and factual situations must be distinguished:

• A criminal investigation involving a construction company or property development.
• The appearance of an investor’s name in documents examined by investigators.
• An individual criminal investigation concerning the investor.
• Re-examination or cancellation of an investment certificate of conformity.
• An administrative review of a previous citizenship acquisition decision.
• Issuance of an individual citizenship cancellation or withdrawal decision.
• Official notification of that decision to the affected person or authorised representative.
• Judicial proceedings challenging the administrative measure.

These stages may be related, but they are not legally interchangeable.

For example, a foreign investor who purchased a genuine property from a developer subsequently investigated for irregularities does not lose citizenship merely because of that commercial connection.

Nevertheless, cancellation of the investment certificate on which citizenship was originally based may create a serious administrative-law issue requiring immediate examination.

For the broader statistical and international context, see our 2026 study on official citizenship revocation figures and international media coverage.

2. Cancellation, Withdrawal and Deprivation of Turkish Citizenship: What Is the Difference?

The terminology used to describe the termination of nationality is not merely academic. Different legal mechanisms have different statutory conditions, temporal consequences, effects on family members and judicial implications.

2.1. Cancellation Under Article 31 of Law No. 5901

Article 31 of the Turkish Citizenship Law provides for cancellation where the decision to grant citizenship resulted from a false declaration by the individual or concealment of material circumstances forming the basis of citizenship acquisition.

The relevant examination concerns the information provided in the application, the circumstances allegedly concealed and their legal relationship with the original naturalisation decision.

A subsequent reassessment of a property’s market value is not necessarily equivalent to establishing that the investor knowingly made a false declaration or concealed material facts.

However, the absence of an objective statutory investment requirement may raise a separate issue under Article 40.

2.2. Withdrawal Under Article 40

Article 40 governs the withdrawal of citizenship acquisition or loss decisions subsequently found to have been issued without the required legal conditions or as duplicate decisions.

The central inquiry is whether the legally required conditions existed at the time the original decision was issued.

Article 66 of the Regulation on the Implementation of the Turkish Citizenship Law provides that a withdrawn decision becomes legally ineffective from the date of the original decision.

This retrospective effect distinguishes withdrawal from cancellation and can generate complex consequences where the individual has subsequently married, had children, established companies, acquired property or relinquished a previous nationality.

2.3. Deprivation Under Article 29

Article 29 establishes a separate statutory mechanism commonly translated as deprivation or loss of citizenship by decision of the competent authority.

Its legal grounds differ from the cancellation of an investment eligibility certificate or a technical review of real estate valuation.

The consequences and notification rules applicable to Article 29 decisions must therefore be assessed separately.

2.4. Why the Distinction Matters

Under Article 32, an Article 31 cancellation decision takes effect from the date of the cancellation decision.

By contrast, the implementing regulation describes Article 40 withdrawal as rendering the earlier decision ineffective from its original date.

Accordingly, a person informed that their Turkish citizenship has been “revoked” must first obtain and analyse the actual administrative decision before selecting an appropriate legal remedy.

Legal sources: Turkish Citizenship Law No. 5901 and the Regulation on its Implementation.

3. How Can I Find Out Whether My Turkish Citizenship Is Still Valid?

A reliable citizenship-status investigation should not be based solely on an online screenshot, an old passport or an informal statement from a third party.

Article 36 of Law No. 5901 provides that official population records, identity documents and passports constitute presumptive evidence of Turkish citizenship unless proven otherwise.

These documents therefore have significant evidentiary value, but their evidentiary presumption may be displaced by a legally relevant decision or contrary official record.

3.1. Directorate General of Population and Citizenship Affairs

The principal administrative authority responsible for citizenship records is the Directorate General of Population and Citizenship Affairs under the Ministry of Interior.

The individual or a duly authorised representative may request information within the limits permitted by the relevant administrative procedures.

The investigation should determine the original citizenship acquisition date, the underlying decision, any subsequent cancellation or withdrawal measure and the relevant notification records.

3.2. Provincial Population and Citizenship Directorates

Provincial authorities have important application and correspondence functions in citizenship procedures.

Article 37 of Law No. 5901 governs applications submitted through the competent governorate in Türkiye or through diplomatic and consular missions abroad, either personally or through an appropriately authorised representative.

However, the ability to submit an application does not establish an unrestricted right to access every confidential document in every governmental file.

3.3. Examination of the Competent Authority’s Decision

For individuals naturalised through an exceptional procedure involving a Presidential decision, it may be necessary to determine whether a subsequent Presidential withdrawal decision has been issued.

Obtaining a decision number alone may be insufficient. Its date, legal grounds, affected individuals and relationship with the original citizenship file should also be confirmed.

Written official confirmation ordinarily provides a stronger basis for legal analysis than an oral representation.

3.4. Separate Examination of Criminal Records

Citizenship-status records and criminal investigation records are maintained for different purposes.

The absence of an identified citizenship cancellation decision does not conclusively establish that no criminal investigation exists. Conversely, the existence of a criminal investigation does not automatically terminate citizenship.

4. My e-Devlet Account Still Works. Does That Prove My Citizenship Remains Valid?

Türkiye’s e-Government platform, known as e-Devlet, provides access to important official services and documents.

Nevertheless, the ability to log in or retrieve previously issued documents does not conclusively establish that no subsequent administrative citizenship decision exists.

4.1. Official Population Registration Extracts

The e-Devlet service titled “Nüfus Kayıt Örneği Belgesi Sorgulama” allows eligible users to obtain official population registration extracts.

A digitally authenticated population record can be important evidence of the status currently recorded by the relevant administration.

However, the absence of a cancellation notation in a particular extract does not necessarily establish that no review is pending or that no decision has yet to be reflected across administrative systems.

4.2. Citizenship Application Enquiries

The citizenship application enquiry service is useful for following an application process.

It should not automatically be treated as a comprehensive legal verification mechanism for every possible subsequent withdrawal decision issued several years after naturalisation.

Directorate General of Population and Citizenship Affairs – e-Devlet Services.

4.3. Turkish Identity Numbers

The continued appearance of a Turkish identity number in historical documents or electronic systems does not, by itself, replace the need to examine the most recent legally operative citizenship decision.

4.4. The Difference Between Technical Records and Legal Status

The issuance of an administrative decision, communication between public institutions, updating of population records and synchronisation of electronic databases may constitute separate steps.

Such distinctions do not diminish the legal importance of population records. Rather, they explain why a complete status assessment must consider the underlying administrative decision as well as the available official records.

5. Which Documents Should Be Examined in an Official Citizenship File?

A comprehensive legal review should organise the available documents according to their legal function.

5.1. Documents Relating to the Original Acquisition

These may include the citizenship application date, statutory grounds of naturalisation, application reference number, original decision number, the decision date and the documents evidencing notification.

For investment-based applications, the property title deed, investment certificate of conformity, valuation reports, foreign-currency documents and the legislation applicable on the investment date are especially important.

5.2. Documents Relating to a Possible Cancellation or Withdrawal

• The individual cancellation or withdrawal decision, if any.
• The statutory and regulatory provisions relied upon.
• The decision date and official reference number.
• The factual allegations or findings relied upon against the individual.
• Documents showing communication to relevant authorities.
• Notification records concerning the individual or authorised representative.
• Changes made in the population registration system.
• Any subsequent correction or reconsideration decisions.

5.3. Investment Certificates and Citizenship Decisions Are Distinct

A property investment certificate of conformity and the subsequent decision granting Turkish citizenship are separate administrative instruments.

Cancellation of a conformity certificate may provide the factual and legal basis for the withdrawal of an earlier naturalisation decision.

However, the legality of each administrative act and the available judicial remedies should be independently considered.

This distinction was particularly significant in the Council of State’s decision numbered E.2024/405, K.2026/361, which concerned allegedly inaccurate foreign-exchange purchase documents and the subsequent cancellation of a property investment certificate.

5.4. Individual Files of Family Members

The principal investor’s file may contain important information about family members, but the citizenship acquisition date and legal grounds applicable to each spouse and child should be examined separately.

Children born after the original naturalisation, spouses who acquired citizenship independently and family members whose status arose under different provisions may require different legal assessments.

6. What Happens If I Never Received Official Notification of My Citizenship Cancellation?

Notification is one of the most important procedural questions for naturalised Turkish citizens residing outside Türkiye.

Article 41 of Law No. 5901 governs the notification of decisions concerning citizenship acquisition and loss.

A specific publication mechanism exists for deprivation decisions under Article 29. Other cancellation or withdrawal decisions should not automatically be treated as notified merely because a newspaper or government press release discussed the broader investigation.

6.1. Does the Absence of Notification Mean No Decision Exists?

No. The legal existence of an administrative decision and notification of that decision are distinct issues.

Article 32 expressly provides that an Article 31 cancellation decision takes effect from the date of the decision.

Consequently, absence of notification does not necessarily establish that the administrative act is legally nonexistent or incapable of producing any legal consequences.

Nevertheless, missing or defective notification may be highly significant for the commencement of judicial filing periods and access to an effective legal remedy.

6.2. Individuals Residing Abroad

Several explanations may exist where a person residing abroad has not personally received any document.

The administrative authority may not yet have completed the notification process. The address on record may be outdated. The notification may have been transmitted through a diplomatic mission, or another legally permitted service method may have been used.

Residence outside Türkiye does not automatically invalidate all official notifications.

Likewise, the absence of personal physical delivery does not conclusively establish that no legally effective notification occurred.

6.3. Notification to an Authorised Attorney

Where an attorney has been validly authorised to receive documents relating to citizenship proceedings, service upon that representative may have important consequences for the filing period.

In its decision E.2025/6295, K.2025/7133, the Council of State’s 10th Chamber treated notification to the authorised attorney as relevant to the commencement of the statutory period.

Therefore, individuals who previously retained legal counsel should examine former powers of attorney and the existence of any prior notifications.

7. When Does the Deadline for Challenging a Citizenship Decision Begin?

Judicial filing deadlines are a central concern in Turkish administrative litigation.

A potentially strong substantive argument against a citizenship withdrawal decision does not eliminate the consequences of failing to institute proceedings within the legally applicable period.

7.1. The General 60-Day Filing Period

Under Article 7 of Administrative Judicial Procedure Law No. 2577, the general period for initiating an administrative action before the Council of State or an administrative court is 60 days unless another applicable law provides a different period.

Article 8 governs the calculation of periods, generally beginning from the day following the legally relevant notification, publication or announcement.

However, the identification of the legally effective starting date requires examination of the decision, its notification method and the applicable procedural rules.

7.2. Administrative Applications Under Article 11

Article 11 permits an eligible person, within the judicial filing period, to request the withdrawal, annulment, amendment or replacement of an administrative decision from the competent superior authority or, in the absence of such an authority, the authority that issued the decision.

A qualifying Article 11 application suspends the running of the judicial filing period.

Where no response is given within 30 days, the request is deemed rejected under the applicable statutory rule. Following express or implied rejection, the remaining judicial filing period continues to run, taking account of the time that elapsed before the application.

Not every administrative letter automatically qualifies for this legal effect. The nature of the request, its recipient and the statutory conditions must be examined.

7.3. Does a Request for Information Suspend the Filing Period?

Merely asking an authority for a document, a copy of a file or confirmation of citizenship status should not automatically be treated as an Article 11 application capable of suspending a running litigation deadline.

A request for access to information and a formal request to withdraw an existing administrative decision are legally distinct.

Accordingly, an individual who has already become aware of a withdrawal decision may face procedural risks by waiting for documents without evaluating the filing deadline.

7.4. The Importance of Notification Evidence

A complete legal review should identify who received the notification, on what date, with which authority and through which method.

Where electronic notification or service abroad is involved, the relevant special procedural rules must also be considered.

Statutory source: Administrative Judicial Procedure Law No. 2577.

8. Important Council of State Decisions from 2025 and 2026

Judicial decisions demonstrate why citizenship disputes cannot be resolved merely by referring to general media statements.

The following cases concern different legal issues: the sufficiency of evidence, allegedly false investment documents and compliance with the statutory filing period.

8.1. Council of State, 10th Chamber, E.2024/3835, K.2026/324, February 4, 2026

Subject: Withdrawal of Turkish citizenship on national-security and public-order grounds.

The case concerned an individual who had acquired Turkish citizenship through an exceptional naturalisation procedure.

The administration subsequently relied on Article 40 of Law No. 5901 to withdraw the original citizenship decision, citing national-security and public-order concerns.

The Council of State examined whether the legal and factual circumstances necessary to justify withdrawal had been established through sufficient, specific and serious evidence.

The decision addressed the significance of circumstances existing when citizenship was originally acquired, rather than simply treating later allegations as conclusive proof that the earlier statutory conditions had been absent.

The court concluded that the factual and legal basis presented was insufficient to justify the contested withdrawal as applied to the claimant.

Accordingly, the relevant part of the Presidential withdrawal decision was annulled.

Legal significance: The state’s authority over nationality does not eliminate the requirement that an administrative withdrawal decision be supported by lawful and adequately established grounds.

This was not a property-valuation dispute. Nevertheless, the reasoning is important for the judicial assessment of the evidence and legal grounds relied upon in citizenship withdrawal cases.

Council of State – Full Decision, E.2024/3835, K.2026/324.

8.2. Council of State, 10th Chamber, E.2024/405, K.2026/361, February 5, 2026

Subject: Investment citizenship, inaccurate foreign-exchange purchase documents and cancellation of the certificate of conformity.

The dispute involved a foreign national who had obtained Turkish citizenship through a property investment.

The claimant maintained that the investment payment had been made and that the competent authorities had accepted the application and issued the necessary documentation.

However, the authorities subsequently determined that documents concerning foreign-currency purchases had been inaccurately prepared.

The property’s investment certificate of conformity was cancelled, and the original citizenship decision was subsequently withdrawn under Article 40.

The Council of State examined whether the statutory requirements for acquisition through investment had actually been fulfilled.

The cancellation of the certificate of conformity, together with the absence of a successful legal challenge to that certificate decision, was significant in the court’s assessment.

The court found no illegality in the withdrawal of the citizenship decision and dismissed the action.

Legal significance: The previous issuance of an investment certificate does not necessarily prevent withdrawal where the required statutory conditions are subsequently established not to have existed.

Importantly, the case involved the historic investment requirements applicable to the investor’s original transaction. The current USD 400,000 property threshold should not be retroactively substituted for the threshold applicable at that earlier time.

Council of State – Full Decision, E.2024/405, K.2026/361.

8.3. Council of State, 10th Chamber, E.2025/6295, K.2025/7133, December 30, 2025

Subject: Notification to an authorised lawyer and expiry of the judicial filing deadline.

The case concerned a decision withdrawing Turkish citizenship.

The relevant notification was delivered to the claimant’s authorised lawyer on April 10, 2025.

The proceedings were not initiated until December 20, 2025.

The Council of State held that the applicable 60-day filing period had elapsed and dismissed the case as time-barred without examining the substantive legality of the contested withdrawal.

Legal significance: Even where a claimant believes the citizenship withdrawal is unlawful, judicial proceedings must comply with applicable procedural deadlines.

Notification to an attorney authorised to receive relevant documents may start the filing period. Appointing a different lawyer does not automatically restart that period.

Council of State – Full Decision, E.2025/6295, K.2025/7133.

8.4. Comparative Assessment of the Three Decisions

Read together, these decisions demonstrate that the outcome depends on the specific grounds for withdrawal, the underlying evidence, the prior administrative steps and the procedural history of the case.

The availability of subsequent appeals and the finality of these decisions must be verified individually. No general assumption concerning the exhaustion of all judicial remedies is made here.

9. Which Court Has Jurisdiction Over Turkish Citizenship Cancellation?

The competent judicial forum depends on the authority responsible for issuing the contested administrative act.

Under Article 24 of Council of State Law No. 2575, the Council of State has first-instance jurisdiction over annulment proceedings brought against Presidential decisions.

However, a separate decision cancelling a property investment certificate, or a decision issued by another administrative authority, may fall within the jurisdiction of a different administrative court.

It would therefore be incorrect to assume that all disputes concerning Turkish citizenship must necessarily be filed before the same court.

9.1. Suspension of Execution

Under Article 27 of Administrative Judicial Procedure Law No. 2577, filing an annulment action does not automatically suspend the execution of the challenged administrative decision.

A suspension-of-execution decision generally requires the cumulative evaluation of manifest unlawfulness and the risk of damage that would be difficult or impossible to remedy if the administrative act were implemented.

In citizenship cases, the consequences affecting passports, lawful residence, family relationships, professional activity and property may be relevant to that assessment.

However, serious consequences do not guarantee that a court will grant interim relief.

9.2. Multiple Administrative Acts

One factual dispute may involve several distinct administrative decisions: cancellation of a certificate of conformity, withdrawal of citizenship, modification of population records, invalidation of travel documents or subsequent immigration measures.

Each act must be identified and evaluated according to its own legal character and available procedural remedies.

10. What Happens to My Turkish Passport and Identity Card If My Citizenship Is Cancelled?

A Turkish passport and national identity card are official documents issued in connection with the individual’s Turkish citizenship status.

Article 36 of Law No. 5901 recognises their evidentiary significance for the proof of citizenship.

Nevertheless, if the underlying legal status is subsequently terminated, the continued validity of those documents must be examined independently.

10.1. A Passport’s Printed Expiry Date

The printed expiry date does not guarantee that the legal status supporting the passport’s issuance remains unchanged throughout its stated validity period.

Physical possession of the passport and its current legal usability are separate questions.

10.2. Collection or Invalidity of Documents

Where citizenship has legally ended, competent authorities may initiate separate procedures concerning the person’s Turkish identity and travel documents.

However, not every administrative decision necessarily produces identical passport-related action on the same date.

The actual decision and the applicable implementation measures should be identified.

10.3. Consular Appointments

Individuals living abroad may consider visiting a Turkish consulate to enquire about their legal status.

Where citizenship status is uncertain, the purpose of the consular visit and the potential treatment of existing documents should be evaluated beforehand.

There can be no general assurance that every passport will be retained by the holder, nor a general assertion that every document will necessarily be collected.

11. Can a Person Under Citizenship Review Enter Türkiye?

International travel is a central concern for people whose Turkish citizenship is subject to review.

The legal analysis requires consideration of nationality law, immigration legislation, passport requirements and criminal procedure.

11.1. If Turkish Citizenship Remains Legally Valid

Where the individual remains a Turkish citizen, entry into Türkiye is considered under the constitutional and statutory rules applicable to Turkish nationals.

Article 23 of the Constitution provides that a citizen cannot be deported or deprived of the right to enter the country.

However, separate criminal or judicial measures concerning the person may still require examination before travel.

11.2. If Turkish Citizenship Has Legally Ended

Where Turkish citizenship has been terminated, entry into Türkiye may become subject to the immigration rules applicable to foreign nationals.

Possession of a valid foreign passport, satisfaction of any visa requirements and the absence of applicable entry restrictions become relevant.

The loss of Turkish citizenship does not mean that possession of a foreign passport alone guarantees entry.

11.3. Should I Travel With My Turkish or Foreign Passport?

This question cannot responsibly be answered without examining the individual’s legal status and travel documents.

A person who previously acquired Turkish citizenship may no longer be entitled to rely on a Turkish passport if the underlying nationality decision has been legally withdrawn or cancelled.

Conversely, unverified rumours do not establish that Turkish citizenship has necessarily ended.

Before travel, the applicable citizenship status, lawful travel document, visa position and relevant judicial or administrative restrictions must be determined.

11.4. Possible Collection of Passports at Border Control

Passport invalidity, collection of a travel document, seizure under criminal procedure and immigration-related border measures may rest on different legal grounds.

If a person encounters such action, the identity of the authority, the stated legal grounds and the official record of the measure are important.

11.5. Residence Following Entry

A person entering Türkiye as a foreign national must consider the applicable period of lawful stay and any residence permit requirements.

Previous residence as a Turkish citizen does not necessarily create an automatic, unlimited right of residence following citizenship loss.

12. Does a Citizenship Review Mean That I Am Also Under Criminal Investigation?

Criminal investigations and administrative citizenship proceedings may rely on overlapping facts but constitute separate legal processes.

An investment file may be reviewed because evidence was obtained in a criminal investigation involving a developer or an intermediary.

That does not necessarily mean that the investor is personally classified as a criminal suspect.

12.1. Suspects, Witnesses and Victims

The person’s procedural status is essential.

A suspect is a person under investigation for allegedly committing a criminal offence. A witness may possess information relevant to the investigation. A victim or person harmed by a suspected offence may possess different procedural rights.

Confusing these statuses can lead to inaccurate assessments of legal risk.

12.2. Being Summoned for a Statement Is Not the Same as an Arrest Warrant

A summons to provide a statement to the police or prosecutor does not by itself establish that an arrest or detention warrant exists.

Nevertheless, questioning concerning an investment transaction may require careful legal preparation, review of financial evidence and the assistance of an interpreter where appropriate.

12.3. Confidentiality and Access to Investigation Files

Access to a criminal investigation file depends on the person’s procedural status, counsel’s authority and any applicable statutory restrictions.

The fact that a file is not visible to the individual through UYAP does not conclusively demonstrate that no investigation exists.

Likewise, the ability of an attorney to conduct an initial enquiry does not necessarily entail unrestricted access to every document in a confidential investigation.

12.4. Does Acquittal Automatically Restore Citizenship?

A decision not to prosecute, commonly called KYOK in Turkish practice, or a criminal acquittal does not automatically annul every separate administrative citizenship decision.

However, the outcome of criminal proceedings may provide significant evidence in subsequent or pending administrative litigation, depending on the factual and legal grounds relied upon by the administration.

For a detailed assessment, see Turkish Citizenship Cancellation and Criminal Investigations in 2026: KYOK, Acquittal and Judicial Remedies.

13. If My Turkish Citizenship Is Cancelled, Will My Spouse and Children Also Lose Citizenship?

Family members may be affected by the cancellation or withdrawal of the principal investor’s citizenship.

However, it is not legally appropriate to assume that every member of the family necessarily holds citizenship on the same legal basis.

13.1. Spouses and Children Naturalised Through the Principal Investor

Article 32 of Turkish Citizenship Law No. 5901 expressly provides that a cancellation decision also applies to spouses and children who acquired Turkish citizenship dependently through the person concerned.

Accordingly, cancellation under Article 31 may directly affect family members whose citizenship was acquired through that relationship.

Nevertheless, the legal grounds and dates of each family member’s acquisition must be examined.

13.2. Children Born After Naturalisation

Children born after the initial citizenship acquisition may raise different legal questions.

Article 7 of Law No. 5901 governs acquisition of Turkish citizenship by descent.

A child who acquired citizenship by birth through a Turkish parent may have a different initial legal basis from a child naturalised together with the principal investor.

Where the parent’s citizenship is subsequently withdrawn with retrospective effect, additional questions arise concerning how the parent’s nationality at the date of the child’s birth should legally be assessed.

Such matters require specific legal analysis rather than an automatic conclusion.

13.3. A Spouse Who Acquired Citizenship Independently

If a spouse acquired Turkish citizenship through an independent statutory mechanism, the effect of the principal investor’s citizenship decision must be assessed separately.

Marriage alone does not establish that every independently acquired nationality status automatically terminates.

13.4. Children Holding Another Nationality

The existence of a second nationality may be relevant to the practical consequences of citizenship loss.

However, the child’s legal status must be examined under both Turkish nationality law and the nationality legislation of the other state.

13.5. Separate Representation and Litigation

Where separate administrative measures concern individual family members, distinct issues of notification, legal capacity, representation and judicial filing may arise.

This is particularly important where children have reached the age of majority.

14. Can I Recover My Former Nationality If Turkish Citizenship Is Withdrawn?

Not every foreign national who acquired Turkish citizenship retained a previous nationality.

Some states permit dual nationality, while others impose different conditions on acquiring a foreign citizenship or on retaining nationality after naturalisation abroad.

Some individuals may also have formally relinquished their previous nationality.

14.1. Individuals Holding Dual Nationality

Where a person remains a national of another state, the termination of Turkish citizenship does not automatically terminate that foreign nationality.

Nevertheless, the legal validity of foreign travel documents and the nationality rules of the other state should be checked.

14.2. Individuals Who Renounced Their Previous Nationality

Where the individual relinquished a previous nationality, the termination of Turkish citizenship may create a risk of statelessness.

It cannot be assumed that the former nationality will automatically be restored.

Reacquisition depends on the law of the relevant foreign state.

14.3. Statelessness Determination

Statelessness is generally concerned with a person who is not considered a national by any state under the operation of its law.

However, the loss of Turkish citizenship does not automatically mean that a person has been formally recognised as stateless for administrative purposes.

Applicable determination procedures and documentary requirements may need to be addressed separately.

15. What Happens to My Property, Bank Accounts or Company in Türkiye?

Termination of Turkish citizenship and termination of private property rights are distinct legal matters.

Ownership of immovable property, banking assets and corporate participation are regulated through different legal frameworks.

15.1. Ownership of Real Estate

The termination of Turkish citizenship does not mean that every property owned by the individual automatically becomes state property.

Article 33 of Law No. 5901 contains specific provisions concerning the liquidation of property in certain citizenship cancellation cases.

Where liquidation is legally required, the cancellation decision must address that issue and the statutory procedure must be followed.

Article 33 also addresses the postponement of liquidation where the cancellation decision is challenged before the courts.

Importantly, the historic legislative reference in Article 33 to Law No. 5683 must be considered together with the later repeal of that legislation and the current framework under Law No. 6458.

15.2. Foreign Ownership Restrictions

Foreign natural persons may own real estate in Türkiye subject to the applicable legislation, nationality-based conditions and property-related restrictions.

Accordingly, the situation of a former Turkish citizen must be assessed with reference to their current nationality, the type and location of the property and applicable foreign ownership rules.

15.3. Company Ownership

The loss of citizenship does not, by itself, automatically extinguish all private-law rights associated with company shares.

However, rules concerning foreign participation, company management, employment permissions and regulated sectors may become relevant.

15.4. Bank Accounts and Financial Assets

Bank accounts are additionally governed by banking regulations, customer identification requirements and any applicable judicial or administrative measures.

Citizenship loss, account restrictions and criminal seizure orders must not be treated as identical legal events.

16. Can I Continue Living in Türkiye After Losing Turkish Citizenship?

An individual whose Turkish citizenship has legally ended may need to regularise their position under immigration law.

Previous long-term residence, property ownership or family connections do not automatically confer an unrestricted right of residence after nationality has ended.

Nevertheless, family ties, employment, property ownership and other personal circumstances may be relevant to the availability of particular residence permit categories.

Residence permits, deportation decisions and administrative immigration detention are distinct legal measures.

Loss of citizenship does not automatically establish that the person must be immediately deported or placed in immigration detention.

These matters must be evaluated under Law No. 6458, including its separate judicial procedures and potentially different filing deadlines.

Law No. 6458 on Foreigners and International Protection.

17. I Live Outside Türkiye. Can a Turkish Lawyer Investigate My Citizenship Status?

A properly executed power of attorney can be an important instrument for individuals residing abroad who need legal representation in Türkiye.

Article 37 of Law No. 5901 permits relevant citizenship applications through appropriately authorised representatives, subject to the statutory requirements.

The legal effectiveness of a particular power of attorney depends on its form, content and the authority required for the intended action.

17.1. Powers of Attorney Issued at Turkish Consulates

Turkish diplomatic and consular missions abroad may provide notarial services under the applicable conditions.

Individuals should verify appointment requirements, identification documents, interpreter arrangements and the requested authorisation wording before attending.

17.2. Powers of Attorney Issued by Foreign Notaries

A document executed before a foreign notary may require an apostille or another legally recognised method of authentication before it can be used in Türkiye.

The appropriate process depends on the foreign state’s treaty participation and the requirements of Turkish law.

Not every state participates in the Hague Apostille system. Therefore, consular or diplomatic legalisation may be necessary in some cases.

Turkish translation and domestic notarial formalities may also be required.

Republic of Türkiye – Consular Information.

17.3. Scope of Authorisation

Depending on the circumstances, the power of attorney may need to authorise the representative to request information, inspect citizenship records, receive official notifications, submit administrative applications, institute proceedings and conduct related litigation.

Nevertheless, a broad power of attorney does not provide unrestricted access to confidential government information where access is limited by law.

17.4. Previously Appointed Lawyers

Where a former lawyer has acted on the individual’s behalf, the existing powers of attorney and prior proceedings should be examined.

In particular, an earlier notification to an authorised lawyer may already have triggered a statutory filing period.

Issuing a new power of attorney does not automatically invalidate the procedural effects of prior lawful notifications.

18. What Should I Do If I Suspect My Turkish Citizenship Has Been Cancelled?

A structured legal strategy begins with verification of the person’s official status, followed by consideration of the appropriate response to the particular administrative or judicial measures identified.

Step 1: Organise Existing Documents

Collect the original citizenship decision information, Turkish passport, identity card, population registration extracts, investment documents and any official correspondence.

Step 2: Verify the Official Citizenship Status

Examine accessible official records to determine whether an individual cancellation or withdrawal decision exists and identify its date, legal basis and administrative consequences.

Step 3: Check Notification and Filing Deadlines

Review personal notification records, notices delivered to former attorneys, consular correspondence and other lawful service methods.

Where an administrative decision exists, prompt evaluation of the applicable judicial deadline is essential.

Step 4: Examine Criminal Proceedings Separately

Where legally possible, determine whether a criminal investigation concerns the person or the relevant property transaction and identify the individual’s procedural status.

Step 5: Establish the Investment Evidence Chain

For real estate-based naturalisation, review title deeds, contracts, valuation reports, certificates of conformity, SWIFT records, foreign-exchange purchase documents and bank statements.

The objective is not merely to establish that documents exist, but to evaluate whether they prove a genuine transaction satisfying the requirements applicable at the time.

Step 6: Examine Family Members Separately

Identify when and under which legal provisions each spouse or child acquired citizenship.

Step 7: Assess Travel and Residence Consequences

Before travelling, review the legal validity of travel documents, the person’s current nationality, relevant immigration rules and any known judicial or administrative restrictions.

Step 8: Select the Appropriate Legal Remedy

Where no adverse decision has yet been issued, official enquiries, evidence organisation and examination of investment compliance may be priorities.

Where a decision has already been made and notified, protection of the applicable litigation deadline and consideration of judicial remedies may take precedence.

19. Common Misconceptions About Turkish Citizenship Cancellation

“My e-Devlet account works, so I am definitely still a Turkish citizen.”

Electronic access alone is not conclusive. The current official records and any subsequent legally operative administrative decisions must be examined.

“I still have my Turkish passport, so no cancellation decision can exist.”

Physical possession of a passport is not definitive evidence that no subsequent decision has been issued.

“I bought an apartment from an investigated company, so my citizenship was automatically cancelled.”

Buying property from a company under investigation does not by itself establish the termination of an individual’s citizenship.

“I live abroad, so a notification cannot affect my filing deadline.”

Lawful notification methods can apply to persons living abroad. Service upon an appropriately authorised attorney may also have procedural consequences.

“Appointing a new lawyer restarts the lawsuit deadline.”

A change of legal representation does not, by itself, restart a statutory filing period.

“If the prosecutor closes my criminal case, citizenship will automatically be restored.”

A criminal non-prosecution decision and an administrative citizenship decision belong to different legal proceedings. Their interaction requires separate analysis.

“Filing a lawsuit immediately makes my Turkish passport valid again.”

Filing an administrative action does not automatically suspend the challenged decision. Separate interim relief or a relevant judicial ruling may be required.

“If I lose citizenship, my house automatically belongs to the Turkish state.”

Nationality, property ownership and the exceptional statutory rules governing liquidation must be distinguished.

“The citizenship of every member of my family must have the same outcome.”

The legal basis and date of nationality acquisition may differ among family members.

“My original investment certificate makes citizenship withdrawal legally impossible.”

The Council of State’s decision K.2026/361 demonstrates that cancellation of a certificate and the failure of the underlying investment to meet statutory conditions may be decisive in a withdrawal dispute.

20. Conclusion: Turkish Citizenship Status Must Be Determined Through Official Records and Individual Legal Analysis

The developments of 2025 and 2026 have produced understandable uncertainty for individuals who acquired Turkish citizenship through investment or exceptional naturalisation procedures.

However, the question of whether a specific person’s Turkish citizenship has been cancelled or withdrawn cannot be answered solely by reference to press announcements, social-media lists or transactions involving a company under investigation.

Likewise, access to e-Devlet, possession of a passport or availability of historical population records cannot conclusively exclude the possibility of a subsequent administrative decision.

Turkish Citizenship Law No. 5901 establishes different regimes for cancellation, withdrawal and deprivation of nationality, each with different conditions and consequences.

The Council of State decisions examined in this article demonstrate the practical importance of these distinctions.

In one case, insufficient factual and legal grounds resulted in the annulment of a citizenship withdrawal decision. In another, inaccurate investment documents and cancellation of the underlying certificate supported the legality of withdrawal. In a third, the court dismissed proceedings without addressing the substance because the filing deadline had been missed.

The appropriate starting point for an affected individual is therefore a systematic investigation of official citizenship records, any existing administrative decision, the legal basis for that decision, the notification history, relevant criminal proceedings and the available judicial remedies.

Legal certainty in nationality law does not mean that citizenship decisions can never be reviewed. It means that the termination of nationality must rest on lawful grounds, established facts and effective judicial scrutiny.
