Contesting a Will in Turkey: Civil Code Articles 557–559 for Foreign Heirs
1. What does a will-cancellation action do?
A will-cancellation action (vasiyetnamenin iptali davası) attacks the legal validity of a testamentary disposition. It is not the same remedy as a reserved-share reduction action. Cancellation asks the court to remove the testamentary disposition, or the affected part of it, because one of the statutory invalidity grounds in Article 557 exists.
The distinction is essential. A will may be formally and substantively valid but still infringe a protected heir’s reserved share; that problem is addressed through reduction. Conversely, a will may stay within the disposable portion but be invalid because the testator lacked capacity or the required form was not observed. The correct claim depends on the legal defect.
For foreign heirs, the first procedural step is usually to obtain the opened will and its court record. Under Articles 595–597, wills found after death must be delivered to the Civil Court of Peace, opened and read, and the relevant provisions notified to interested persons. See our guide on opening and reading a will in Turkey.
2. Article 557(1): lack of testamentary capacity
The first statutory ground is that the testamentary disposition was made when the testator lacked the legal capacity to make it. The relevant question is the testator’s condition at the time the disposition was executed, not simply whether the person later became ill or elderly.
A capacity dispute must therefore be built around dated evidence. Medical records, hospital files, prescription history, cognitive assessments, witness observations and the circumstances of execution can be relevant. A diagnosis alone does not automatically answer the legal question; the court examines whether the statutory capacity requirement existed at the moment of the testamentary act.
Where the testator lived abroad, medical records may come from another country. Those records should be obtained in full, authenticated where necessary and translated into Turkish. A short family statement that “the deceased was confused” is not a substitute for a properly documented evidentiary file.
3. Article 557(2): mistake, fraud, fear or coercion
Article 557 separately permits cancellation where the testamentary disposition resulted from mistake, fraud, fear or coercion. These grounds focus on whether the testator’s free and informed testamentary intention was distorted.
Mistake concerns an erroneous belief affecting the testamentary act. Fraud involves deceptive conduct that causes the testator to make the disposition. Fear and coercion address pressure that prevents the document from reflecting the testator’s genuine will.
Evidence commonly includes communications, financial records, witness testimony, the testator’s prior consistent estate plan, sudden unexplained changes, isolation from family, and the circumstances in which the will was prepared and signed. No single fact replaces the statutory test. The claimant must connect the evidence to the specific invalidity ground relied upon.
Foreign heirs should preserve messages and digital records before devices, email accounts or cloud data become inaccessible. Cross-border family disputes often turn on contemporaneous evidence created before the death rather than statements made after litigation begins.
4. Article 557(3): unlawful or immoral content, conditions or burdens
The third ground applies where the content of the disposition, a condition attached to it, or a burden imposed by it is contrary to law or morality. The court examines the actual testamentary provision rather than merely whether other family members consider it harsh or unfair.
Turkish succession law gives a testator meaningful freedom within statutory limits. A beneficiary receiving more than another person is not by itself an Article 557(3) invalidity ground. If the complaint is that a protected heir’s reserved share has been infringed, the proper legal route is usually reduction under the reserved-share provisions rather than cancellation for illegality.
Our guide on reserved shares under Turkish Civil Code Articles 505–506 explains the separate protected-share analysis.
5. Article 557(4): failure to comply with the legally required form
The fourth ground is failure to observe the form required by law. Testamentary dispositions are formal legal acts. A document that expresses a person’s wishes but does not satisfy the applicable form rules may therefore be vulnerable to cancellation.
For a Turkish-form will, the relevant Civil Code provisions distinguish official wills, handwritten wills and oral wills made in the exceptional statutory circumstances. Each form has its own legal conditions. A document should not be classified merely by its heading. The court looks at how it was actually prepared, signed, witnessed, dated and preserved.
Where the will was made abroad, the private-international-law analysis becomes central. The form and effect of a foreign testamentary disposition cannot be assessed solely by comparing it with a Turkish domestic template. Law No. 5718 and applicable international rules determine the relevant conflicts framework.

6. Who can file the action? Article 558
Article 558 gives the right to sue to an heir or testamentary beneficiary who has an interest in cancellation of the disposition. The action may seek cancellation of the entire testamentary disposition or only part of it.
Standing therefore requires more than general family dissatisfaction. The claimant must show a legally protected interest affected by the challenged testamentary act. A person who would receive nothing even if the clause were cancelled may lack the required interest in that particular cancellation.
Article 558 also addresses defects arising from participation by persons receiving benefits under the will. Where the invalidity is based on the participation of beneficiaries, their spouses or relatives in the creation of the testamentary disposition, the statutory consequence can be confined to the benefits made to those persons rather than automatically destroying unrelated provisions.
7. Article 559: one-year, ten-year and twenty-year forfeiture periods
Article 559 contains one of the most important rules in will litigation. The right to bring a cancellation action is subject to forfeiture periods, not an open-ended timetable.
The first period is one year. It starts when the claimant learns three matters: the testamentary disposition, the reason for invalidity and the fact that the claimant is entitled to challenge it. Waiting for family negotiations to finish does not replace a statutory deadline calculation.
Article 559 also sets long-stop periods. Against defendants in good faith, the action is barred after ten years; against defendants in bad faith, the long-stop period is twenty years, calculated from the statutory starting point stated in Article 559. The Code differentiates wills and other testamentary dispositions for the start of the absolute period, so the date analysis must be performed from the actual document and procedural history.
Finally, Article 559 expressly provides that invalidity may always be raised by way of defense. That rule does not mean an expired affirmative cancellation claim can simply be relabeled. It means the statute preserves the defensive assertion of invalidity in the circumstances covered by the provision.
The current wording of Articles 557–559 appears in the official Ministry of Justice publication of the Turkish Civil Code.
8. Foreign wills, foreign heirs and Law No. 5718
A foreign nationality does not take the dispute outside Turkish private international law. Article 20 of Law No. 5718 generally points succession to the deceased’s national law, while Turkish law governs immovable property located in Turkey. The applicable law must therefore be identified asset by asset before the substantive validity analysis is completed.
Article 2 of Law No. 5718 requires the Turkish judge to apply the conflict-of-laws rules and the foreign law designated by them ex officio. The parties may be asked to assist in establishing the content of foreign law. The official text is available from the Ministry of Justice.
For Turkish immovable property, the succession analysis must account for the direct Turkish-law rule in Article 20. See our broader guide on Turkish inheritance law for foreigners under MÖHUK Article 20.
9. Evidence and litigation strategy for a foreign heir
A well-founded cancellation action starts with the complete testamentary file, not a translated excerpt sent by a relative. Obtain the will, the court opening record, service documents, the death certificate and the inheritance-certificate file. Then identify the exact Article 557 ground for each challenged provision.
Capacity claims require evidence from the execution date. Fraud or coercion claims require proof of the conduct that distorted the testator’s intention. Form claims require the original instrument or a legally reliable copy and evidence of how it was executed. Unlawful-condition claims require precise analysis of the clause itself.
Foreign evidence should be prepared in a form usable in Turkish proceedings. Depending on the document and issuing country, apostille or legalization may be required, followed by an accepted Turkish translation. See apostille and certified translation for documents used in Turkey.
Most importantly, calculate Article 559 periods at the beginning of the file. A legally strong capacity or coercion argument can fail if the affirmative action is filed outside the applicable forfeiture period.
- Obtain the complete will and official opening record.
- Record the dates of opening, service and actual knowledge.
- Identify the exact Article 557 ground.
- Confirm standing under Article 558.
- Calculate the Article 559 one-year and absolute periods immediately.
- Preserve medical, banking, communication and witness evidence.
- Authenticate and translate foreign documents.
- Determine the applicable law under Law No. 5718 before pleading the merits.
- Separate cancellation claims from reserved-share reduction claims.
- Request interim protection where estate assets face a concrete risk of disposal.
10. Court protection while the will dispute is pending
A cancellation action does not justify allowing estate assets to disappear while the court examines capacity, coercion, form or another Article 557 ground. Where there is a concrete risk that Turkish real estate, company interests, bank assets or other estate property will be transferred in a way that defeats effective judicial protection, the claimant should assess the interim-measure rules of the Code of Civil Procedure together with the inheritance claim. Any request must identify the asset, the threatened act and the legal interest requiring protection; a generic request to freeze an entire estate without connecting the measure to the dispute is not a substitute for the statutory conditions.
The foreign heir should therefore collect current title, company and banking information at the beginning of the case. This also improves the merits analysis: the court can see which testamentary provision affects which asset and why cancellation of that provision matters to the claimant’s legal position.
