Paternity Lawsuit in Turkey: Establishing Fatherhood, DNA Tests and Time Limits

By Av. Talha Yayla · October 20, 2026 · 15 min read

In Turkey (Türkiye), legal fatherhood is established in one of three ways: marriage to the mother, voluntary recognition by the father, or a court judgment in a paternity lawsuit (Turkish Civil Code No. 4721, Art. 282). Where the father will not recognise the child, the mother and the child can sue him — or, if he has died, his heirs — in the family court (Art. 301). The court investigates the facts of its own motion and can order DNA testing; a defendant who refuses the test risks having the result presumed against him (Art. 284). The mother must sue within one year of the birth (Art. 303).

This guide is written for foreign mothers whose child's father is Turkish, for foreign men facing a paternity claim in Turkey, and for adults seeking to establish who their father is. It explains recognition, the lawsuit, the evidence, the time limits, and what a judgment changes: the child's surname, maintenance, inheritance and, where the father is Turkish, citizenship.

Three routes to fatherhood: marriage to the mother, recognition, court judgment (Art. 282).
Presumption for married mothers: a child born during the marriage or within 300 days after it ends is the husband's (Art. 285).
Recognition: written declaration to the civil registrar or the court, or in a notarial deed or will (Art. 295).
Paternity lawsuit: brought by the mother and the child against the father or his heirs (Art. 301).
DNA testing: parties must submit to tests that are necessary and not dangerous to health (Art. 284).
Mother's time limit: one year from the birth (Art. 303).
Mother's own claims: birth costs and six weeks' living costs before and after the birth (Art. 304).
Citizenship: a child of a Turkish father born outside marriage becomes Turkish once paternity is established (Law No. 5901, Art. 7(3)).

Legal status of this guide. It reflects the Turkish Civil Code, the International Private and Procedural Law (No. 5718) and the Turkish Citizenship Law (No. 5901) as in force. Several time limits in this area have been annulled by the Constitutional Court over the years, and the position of the child's own time limit rests on case law. Last updated: October 2026.

How fatherhood is established

Under Turkish law the link between a child and its mother arises automatically at birth. The link with the father does not. Article 282 of the Civil Code lists the ways it can arise: by the father's marriage to the mother, by recognition, or by a judge's decision. Adoption is a fourth, separate route to legal parenthood.

Until one of these exists, the man who is biologically the father is, in law, a stranger to the child. He owes no maintenance, the child does not inherit from him, the child does not carry his surname and cannot derive Turkish citizenship from him. This is why establishing paternity matters so much in practice, and why the law gives the child a right of action of its own, independent of the mother's.

Situation	How fatherhood arises	Legal basis
Child born during the marriage, or within 300 days after it ends	Automatically: the husband is the father	Art. 285
Parents marry each other after the birth	Automatically: the child is treated as born in wedlock	Art. 292
Unmarried father willing to acknowledge the child	Recognition (tanıma)	Art. 295
Unmarried father unwilling, or deceased	Paternity lawsuit (babalık davası)	Art. 301

The husband presumption

A child born while the mother is married, or within three hundred days of the end of the marriage, is presumed to be the husband's child (Art. 285). No declaration is needed; the civil registry records the husband as father. A child born later than three hundred days after the marriage ended can still be attributed to the former husband if it is proved that the mother conceived during the marriage.

The presumption has an important consequence for a mother whose child was fathered by someone other than her husband or recent ex-husband. The biological father cannot recognise the child, and a paternity suit against him cannot succeed, until the existing legal link with the husband has been removed (Art. 295). That requires a separate action to deny paternity, discussed below. Where a woman separated long ago but never divorced, this two-step sequence — first removing the husband's paternity, then establishing the true father's — is unavoidable.

Voluntary recognition

Recognition is the simple route. The father declares that the child is his, and no court case is needed. Article 295 allows the declaration to be made:

by written application to the civil registrar (nüfus müdürlüğü);
by written application to the court;
in an official deed drawn up by a notary; or
in a will.

If the man recognising the child is a minor or under guardianship, his parent or guardian must consent. The authority that receives the declaration notifies the registries where the father and the child are recorded, and the child's registry informs the mother and the child (Art. 296).

Recognition is a unilateral act: the mother's consent is not required by the Civil Code. The safeguard runs the other way. The mother, the child, the public prosecutor, the Treasury and other interested persons can sue to annul a recognition if the man is not in fact the father (Art. 298), within one year of learning of the recognition and of the fact that he cannot be the father, and in any event within five years of the recognition; the child can sue within one year of reaching majority (Art. 300). The man himself can ask for annulment only on grounds of mistake, deception or duress (Art. 297).

For a foreign father, or a Turkish father living abroad, recognition can generally be made through a Turkish consulate, which performs civil registry functions. The documents required — proof of the child's birth, identification of both parents, translations and legalisation — vary with the country, so check with the consulate before attending.

The paternity lawsuit

Where the father will not recognise the child, the mother and the child may each ask the court to determine paternity (Art. 301).

Who sues

The mother sues in her own name. The child sues through a representative: because the mother's interests and the child's may diverge, the court arranges for a trustee (kayyım) to represent a minor child in the proceedings. If the mother brings the case it is notified to the trustee, and if the trustee brings it, to the mother. An adult child sues in person.

Who is sued

The alleged father. If he has died, his heirs. The claim is also notified to the public prosecutor and the Treasury, which may take part because a paternity judgment affects civil status and inheritance.

Where

In the family court (aile mahkemesi) — or, where none exists, the civil court of first instance acting as family court — at the domicile of either party at the time of the lawsuit or at the time of the birth (Art. 283). A mother living in Ankara can therefore sue in Ankara even if the father lives in another city or abroad.

When

The case can be filed before or after the birth (Art. 303). Filing during pregnancy is unusual but possible, for example where the father is about to leave the country.

What must be shown

The law helps the claimant with a presumption. If the defendant had sexual intercourse with the mother between the three-hundredth and the one-hundred-and-eightieth day before the birth, he is presumed to be the father; the same applies if intercourse is shown during the actual period of conception even outside that window (Art. 302). The defendant can rebut the presumption by proving that it is impossible for him to be the father, or that another man is more likely to be. In modern practice both the presumption and its rebuttal are overtaken by genetic testing.

DNA testing and evidence

Paternity cases are not ordinary civil disputes in which the judge decides only on what the parties put forward. Article 284 lays down two special rules:

The judge investigates the facts of his or her own motion and evaluates the evidence freely. An admission by the defendant does not end the case on its own; a denial does not prevent the court from ordering evidence.
The parties and third persons are obliged to consent to examinations that are necessary to determine parentage and that pose no danger to their health. If the defendant refuses, the judge may, depending on the circumstances, treat the expected result as having gone against him.

In practice the court orders a DNA comparison between the child, the mother and the alleged father, carried out by the Forensic Medicine Institute or a university hospital's genetics department. Samples are taken under the court's supervision with identity checks. A privately commissioned test from a commercial laboratory can support the claim but does not replace the court-ordered test.

Where the alleged father is abroad, the court can request the sample through international judicial assistance, which takes time. Where he has died, testing can be carried out on close relatives, on stored medical samples, or — as a last resort and by court order — on the remains.

Other evidence remains useful, especially for obtaining interim maintenance before the test result arrives: messages, photographs, travel and hotel records, witness statements from people who knew of the relationship, and payments made by the father towards the pregnancy or the child.

Time limits

Claimant	Time limit	Notes
Mother	One year from the birth (Art. 303)	If the child is legally linked to another man, the year runs from the date that link is removed. If there is a justified reason for delay, the claim can be brought within one month of the reason ceasing.
Child	The provision that limited the child's claim was annulled by the Constitutional Court in 2011	The child's action is therefore treated as not subject to the one-year period. Confirm the current case law before relying on this for an old claim.

The mother's one-year period is short and is a forfeiture period: the court applies it without the defendant having to raise it. A mother who has missed it has not lost everything, because the child's right is separate. The case can still be brought in the child's name through a trustee, and it is the child's claim that carries the long-term consequences — status, maintenance, inheritance and citizenship. What the mother loses with her own deadline is her personal claim for expenses.

Do not wait. Even where a claim is still legally open, delay costs evidence. Fathers move abroad, witnesses lose touch and maintenance cannot be claimed for an unlimited period into the past. If the father is likely to leave Turkey, file before he does.

What the mother can claim

With the paternity suit or separately, the mother may claim from the father or his heirs (Art. 304):

the costs of the birth;
her living expenses for six weeks before and six weeks after the birth;
other expenses required by the pregnancy and the birth.

The judge can award these even if the child was stillborn. Payments the mother received from third parties or social security bodies are deducted to the extent that fairness requires.

For the child, maintenance is claimed together with paternity. Where the judge finds paternity strongly likely, he or she can order appropriate maintenance for the child's needs before the judgment (Art. 333), and more generally can order the defendant to deposit or provisionally pay maintenance while the case is pending (Art. 332). This matters because a contested case with a DNA test obtained from abroad can take a long time. How maintenance is calculated, and how it is enforced when the father does not pay, is covered in our guide to child custody in Turkey for foreign parents.

Is the father refusing to acknowledge the child, or about to leave Turkey? The mother's own claim expires one year after the birth. Message Yayla Law on WhatsApp or use the contact form with the child's date of birth, both parents' nationalities and where the father lives.

What the judgment changes

Civil registry and surname

Once final, the judgment is entered in the civil registry and the father is recorded. Which surname a child born outside marriage carries after paternity is established has been the subject of Constitutional Court rulings and changes in practice; ask for the current rule at the time of registration rather than assuming the father's surname applies automatically.

Maintenance

The father becomes liable for the child's care, education and protection on the same footing as any parent (Art. 327). The obligation lasts until the child reaches majority and continues during education after that, to the extent that can reasonably be expected of the parents (Art. 328).

Custody

Establishing paternity does not transfer custody. Where the parents are not married, custody belongs to the mother. The father acquires the right to request personal contact with the child, and in an appropriate case can ask the court to reconsider custody in the child's interests.

Inheritance

The child becomes a legal heir of the father with exactly the same share as children born in wedlock, including a reserved portion that cannot be removed by will. Where the father has already died, the judgment allows the child to claim against the estate. See our guide to inheritance law in Turkey for foreigners.

Citizenship

A child born to a Turkish mother is Turkish whether or not the parents are married. A child born outside marriage to a Turkish father and a foreign mother acquires Turkish citizenship when the procedures establishing parentage are completed (Law No. 5901, Art. 7(3)). Recognition or a paternity judgment is therefore the key that opens citizenship, with effect from birth. Our guide to citizenship for a child born in Turkey explains the registration steps.

Residence

The foreign mother of a Turkish child does not become a citizen herself, but she is the parent of a Turkish citizen, which is relevant both for residence permit applications and for any deportation assessment.

Foreign elements: which law, which court

Where the mother, the father or the child is foreign, the Turkish court first decides which country's law governs. Under Article 16 of Law No. 5718, the establishment of parentage is governed by a cascade designed to favour the child:

the child's national law at the time of birth;
if parentage cannot be established under it, the law of the child's habitual residence;
failing that, the national law of the mother or of the father at the time of the birth;
failing that, the law of the parents' common habitual residence at the time of the birth;
failing that, the law of the place of birth.

The court moves down the list until it reaches a law under which parentage can be established. For a child living in Turkey, Turkish law will apply at the second step at the latest. An annulment of parentage is governed by the same law under which it was established.

Turkish courts have jurisdiction where the Civil Code's venue rule points to Turkey — the domicile of either party at the time of the suit or of the birth. A foreign mother resident in Turkey can therefore sue a father who lives abroad; service of the claim on him will go through international channels. Conversely, a paternity judgment obtained abroad does not take effect in the Turkish registry by itself: it must be recognised by a Turkish court. The procedure is described in our guide to enforcing a foreign judgment in Turkey.

Foreign claimants should also be aware that a foreign national who sues in Turkey may be asked to deposit security for costs unless exempt on the basis of reciprocity (Law No. 5718, Art. 48), and that no security can be demanded where the claimant has been granted legal aid.

Challenging paternity

The reverse problem — a man recorded as father who is not — is dealt with by the action to deny paternity (soybağının reddi). The husband may sue the mother and the child to rebut the presumption that he is the father; the child also has a right of action. Where the child was conceived during the marriage, the claimant must prove that the husband is not the father (Art. 287); again, DNA evidence decides the matter.

The husband must sue within one year of learning of the birth and of the fact that he is not the father, or that the mother had intercourse with another man around the time of conception. The child must sue within one year of reaching majority. If the delay is justified, the year runs from the date the reason ceases (Art. 289). An overall five-year cut-off that once applied to the husband has been removed from the text following a Constitutional Court ruling.

Since an amendment made in November 2024, where the husband dies, is declared missing or permanently loses capacity before the time limit expires, the action may be brought within one year by his descendants, his mother or father, or the man who claims to be the father (Art. 291). Outside those situations, the biological father has no general right of his own to attack the husband's paternity, which leaves him dependent on the mother or the child acting.

Frequently asked questions

How do I prove paternity in Turkey?

By a court-ordered DNA test. The family court investigates of its own motion and orders genetic testing of the child, the mother and the alleged father. Other evidence of the relationship supports the claim and helps obtain interim maintenance.

Can the father refuse a DNA test?

He is legally obliged to submit to a test that is necessary and not dangerous to health. If he refuses, the judge may treat the expected result as proved against him, taking the other evidence into account.

How long do I have to file a paternity lawsuit in Turkey?

The mother must sue within one year of the birth. The provision that limited the child's own claim was annulled by the Constitutional Court, so the child's action, brought through a trustee or personally as an adult, remains possible later.

Can I sue if the father has died?

Yes. The lawsuit is brought against his heirs. Genetic testing can be carried out on relatives or on stored samples. If paternity is established, the child becomes an heir.

Does my child become a Turkish citizen if the father is Turkish?

Yes. A child born outside marriage to a Turkish father and a foreign mother acquires Turkish citizenship once paternity is legally established by recognition or by court judgment.

Does the mother have to agree to recognition?

No. Recognition is the father's unilateral declaration. The mother and the child can, however, sue to annul a recognition made by a man who is not the father.

Can the father get custody after a paternity judgment?

Not automatically. Custody of a child whose parents are not married belongs to the mother. The father gains the right to seek contact and can apply to the court if the child's interests require a change.

Can a foreign paternity test or judgment be used in Turkey?

A private test is supporting evidence only. A foreign court judgment establishing paternity must be recognised by a Turkish court before it is entered in the Turkish registry.

I am still married to someone else. Can the real father recognise my child?

Not yet. A child born during the marriage or within 300 days after it ends is legally the husband's. That link must first be removed by an action to deny paternity; only then can the biological father recognise the child or be sued.
