Mavi Kart (Blue Card) Turkey: Your Rights After Citizenship

If you were born a Turkish citizen and later gave up that citizenship with official permission — most often to naturalise in Germany — you kept far more than you probably think. Article 28 of Law No. 5901 on Turkish Citizenship says that people in your position continue to enjoy the rights of Turkish citizens, with listed exceptions: there is no obligation to do military service and no right to vote, stand for election or import a vehicle or household goods duty-free (Article 28(2)), and permanent, cadre-based public service posts are closed (Article 28(3)). Everything else stays, subject to provisions on national security and public order (Article 28(1)). The document that proves it is the Mavi Kart, the Blue Card.

So the honest headline is this. You can buy an apartment in Kadıköy on the same terms as the cousin who never left. You can inherit your father's land. You can work without a permit. You cannot vote and you cannot hold a Turkish passport. Often the rights are already there and only the registration is missing — an administrative problem, not a legal one.

What the Blue Card is, and what it is not

The Blue Card is issued, on request, to people who held Turkish citizenship by birth and lost it by obtaining permission to renounce, and to their descendants up to the third degree (Article 28(1) and (6)). It is not available to a foreign spouse. It is not available to someone whose citizenship was revoked rather than surrendered.

It is also not a residence permit, not a work permit and not a passport. You travel to Türkiye on your German or other foreign passport and show the Blue Card at the counter. In immigration terms you remain a foreign national, which matters more than people expect — we come back to that.

If you renounced under the older system you may be holding a pink card (pembe kart). Article 28(7) names the Blue Card — or, if it cannot be shown, a record from the Blue Card Holders' Registry together with your foreign identity document — as what institutions work from, so it is worth replacing the old card.

What you keep

Property: you buy as a citizen, not as a foreigner

This is the most valuable thing the card does. Foreign buyers are governed by Article 35 of the Land Registry Law No. 2644: only nationals of countries designated by the President may buy, within a ceiling of 30 hectares per person nationwide and 10 per cent of the privately owned area of any one district, and military and security zones are checked against the maps supplied to the land registry. That foreigner regime is not the one applied to you: Article 28 keeps a citizen's rights, and the implementing regulation directs that property acquisition be handled under the rules applied to Turkish citizens (Citizenship Regulation Article 52(2)), subject to provisions on national security and public order. The title deed (tapu) is issued in your name through the ordinary citizen procedure.

In practice, some land registry offices outside the big cities start opening a foreigner file out of habit. Say plainly that you are a Blue Card holder under Article 28 and give your Turkish identity number. If the office still refuses, ask for the refusal in writing — that is a decision you can challenge, and one our real estate practice can take up for clients abroad.

Inheritance

Turkish immovable property is always inherited under Turkish law, wherever the deceased lived and whatever passport they held. That is Article 20 of MÖHUK, Law No. 5718 on Private International Law; movable assets follow the deceased's national law. As a Blue Card holder you inherit Turkish real estate on the same footing as a citizen (Article 28(1); Citizenship Regulation Article 52(2)), not under the foreigner rules in Article 35 of the Land Registry Law.

What trips families up is procedure, not entitlement. You need a certificate of inheritance (mirasçılık belgesi). A Turkish notary can issue one, but Article 71/B of the Notaries Law No. 1512 bars notaries from doing so where the certificate requires a trial, where the civil registry records are not sufficient, or where it is requested by foreigners; you then go to the civil court of peace instead. Then there is tax: under the Inheritance and Gift Tax Law No. 7338 the declaration falls due within four months of death where the death and the heir are in the same country, and six months where the death was in Türkiye and you are abroad. Filing late costs penalties; it does not cost you the inheritance.

Work, business and daily life

You do not need a work permit. Turkish employers who insist on one are wrong, and the answer is your Blue Card plus your registry entry. You can be a shareholder, a company director or a sole trader on the same footing as a citizen, and Article 6(4) of the International Labour Law No. 6735 preserves your right to work, so company work for a Blue Card holder does not go through the permit regime. You do not need a residence permit under Law No. 6458 on Foreigners and International Protection (Article 20(1)(f)). Your accrued Turkish social security rights survive the renunciation — Article 28 preserves them expressly. Article 28(2) makes the use of those rights subject to the relevant laws, and enrolling fresh in Turkish general health insurance is a separate question under the social security legislation, so do not assume you are covered.

What you lose, and where there is no workaround

• Voting and standing for election. Not at any level, not from abroad, not with any document.
• Public office. Article 28(3) bars permanent, cadre-based posts under public-law rules, such as the civil service, the judiciary, the prosecution service and the military; a public body can still employ you as a worker or as temporary or contract staff.
• A Turkish passport, and Turkish consular protection in third countries. You are protected by the state whose nationality you now hold.
• Duty-free import of a car or household goods.
• Military service — listed as a loss, but it is what most men were after in the first place.

There is one more that is not in the statutory list and should be. Article 28 preserves your rights without prejudice to provisions on national security and public order. You are still a foreign national for immigration purposes, which means a Blue Card holder can in principle be given an entry ban or a deportation decision on those grounds. If it happens you have seven days to take the deportation decision to the administrative court under Article 53(3) of Law No. 6458, and that deadline is unforgiving — miss it and the merits of your case stop mattering. That is immigration work, and it moves fast.

Registration is the step almost everyone skips

Being entitled to a Blue Card and being recorded as a Blue Card holder are two different things. Since the 2012 amendments made by Law No. 6304, holders and their descendants are entered in a dedicated electronic register, the Blue Card Holders' Registry (Mavi Kartlılar Kütüğü), under Article 8/A of the Population Services Law No. 5490, and Article 28(8) provides for an identity number that is used wherever a Turkish identity number is required.

A common pattern looks like this. Someone renounced in 1998, was handed a pink card, and was deleted from the family register without ever being moved into the Blue Card register. Twenty-five years later the identity number fails at the bank, at the land registry, at the tax office and on the state e-government portal, and they are told they are not in the system. Nothing is wrong with their rights. Their record simply is not where it needs to be.

Apply at any Turkish consulate general — in Germany that means Berlin, Cologne, Munich, Frankfurt, Hamburg, Stuttgart, Düsseldorf and the rest — or at a provincial civil registry directorate (nüfus müdürlüğü) in Türkiye. Take the renunciation certificate (çıkma belgesi), your foreign passport, your foreign identity card, biometric photographs and any old Turkish identity papers you still have.

If you are refused in writing, that is an administrative act and you have 60 days to file at the administrative court under Law No. 2577 on Administrative Procedure. If the office simply does not answer, 30 days of silence counts as a refusal and the 60 days run from that point. Both deadlines are strict.

Your children and grandchildren: what Article 28 covers

This is where the rules are most often misunderstood.

If your child was already a Turkish citizen when you renounced — born to you while you still held citizenship — the child is Turkish by descent under Article 7 of Law No. 5901. Under Article 27(2), a minor child loses Turkish citizenship together with the renouncing parent only where that parent asks for it and the other parent consents, or a judge decides; a child included in your renunciation is covered by Article 28 as your descendant. A child who was an adult, or who was not included, did not lose citizenship through your renunciation and is still a Turkish citizen unless they lost it in their own right, and can be registered. Check the file, because older renunciations were handled under the rules in force at the time.

If your child was born after you lost citizenship and the other parent is not Turkish, the child is not a Turkish citizen (Article 7). The child is nevertheless within Article 28: since the amendment made by Law No. 6304 in 2012, the article covers the descendants of a person who renounced up to the third degree — children, grandchildren and great-grandchildren — who document their descent (Article 28(1) and (5)), and Article 28(6) provides for a Blue Card on request.

Article 28 reaches three generations below the person who renounced, not one. Beyond the third degree, Article 28(4) allows the President to extend the rights further.

The practical point for German families is documentary. A child or grandchild relying on Article 28 has to prove the line of descent to the person who renounced (Article 28(5)), so keep the renunciation certificate and the civil-status documents that link each generation.

Should you take Turkish citizenship back?

Germany's nationality law changed in June 2024 and multiple nationality is now generally permitted, so this question now comes up often. On the Turkish side the route is straightforward: under Article 13 of Law No. 5901, someone who lost citizenship by permission to renounce may apply to reacquire it with no residence requirement, unlike those who lost citizenship by revocation, who face a three-year residence condition under Article 14.

We tell most people to slow down, for three reasons.

• Military service can come back. As a Blue Card holder you have no military service obligation (Article 28(2)); after reacquisition, Article 43(2) of the Military Recruitment Law No. 7179 has your military position dealt with under the provisions of that Law that fit your case, taking your earlier military record into account. The Blue Card itself is withdrawn when citizenship is reacquired (Citizenship Regulation Article 55(2)).
• Sequence against German law. If you naturalised in Germany before June 2024, the German consequences of reacquiring Turkish citizenship depend on German rules and on dates. Get German advice before you file in Türkiye.
• Ask what you actually gain. Usually the honest answer is the vote, a passport, and eligibility for public office. If none of those matter, the Blue Card already gives you the rest, and reacquisition is cost and risk for nothing.

Where it does make sense: you want to stand for election or work in the Turkish public sector, you want a Turkish passport for travel, or you want children born in future to be Turkish citizens by birth. That last one is often the real motive and it is a sound one. Our citizenship practice will tell you honestly which of these applies to you.

Two things that surface the moment you use the card

First, your marital status in the Turkish registry is often wrong. If you married in Türkiye and divorced in Germany, the German decree does not change your Turkish record by itself. Since 2017, Article 27/A of Law No. 5490 on Population Services allows a direct route: the spouses apply together, in person or through their attorneys — or, where one of them has died or is a foreign national, the spouse who is a Turkish citizen may apply alone — at the Turkish consulate in the country where the decree was given or at a population directorate designated by the Ministry, and the foreign divorce is registered without a court case, provided it was given by a competent authority, has become final and is not manifestly contrary to Turkish public policy. If that route is not open to you or registration is refused, you fall back on a recognition case under MÖHUK, which is standard family work.

Second, foreign judgments generally. A German order on maintenance, a debt or a property division cannot be enforced in Türkiye, or relied on as res judicata or conclusive evidence, until it is enforced or recognised under MÖHUK Law No. 5718 (Articles 50 and 58). Article 54 sets the enforcement conditions: reciprocity with the state of judgment; that the judgment does not concern a matter within the exclusive jurisdiction of the Turkish courts; that it is not manifestly contrary to Turkish public policy; and that the person against whom it is enforced was properly summoned and represented. Recognition requires the same conditions except reciprocity (Article 58(1)). Proving them is a matter of evidence, and it is what our recognition and enforcement team spends its time on.

If you want us to look at your position, send four things: a scan of your Blue Card or pink card if you have one, your renunciation certificate, the identity page of your current passport, and the dates of birth of any children together with where they were born. We will tell you in writing whether you are properly registered, what your children are and are not entitled to, and whether reacquiring Turkish citizenship would help you or cost you. Where the answer is that you already have everything you need and should spend nothing, we will say that too.
