Cancellation of Will Lawsuit in Turkey: Grounds for Annulment

In Turkey, a Will (Vasiyetname) is a powerful document, but it is not unbreakable. If strict legal conditions are not met, or if the mental state of the testator is questionable, the court can declare the will null and void.

[!NOTE] 💡 Cultural Context: The “Adli Tıp” Factor

In 90% of cancellation lawsuits, the battle is medical, not legal. The court does not rely on witness testimony alone. The entire medical history of the deceased is sent to the Forensic Medicine Institute (Adli Tıp Kurumu) in Istanbul to determine if they had “legal capacity” on the specific day the will was signed.

Legal Grounds for Cancellation (TMK Art. 557)

Under Article 557 of the Turkish Civil Code, there are only four specific grounds to cancel a will. You cannot cancel it just because “it’s unfair.”

1. Incapacity (Ehliyetsizlik)

The most common ground. The testator must have the “Power of Discernment” at the moment of signing.

• Dementia / Alzheimer’s: If the deceased was suffering from advanced dementia, they legally could not understand the consequences of their actions.
• Medication: Heavy sedation or psychosis can also temporary remove capacity.

2. Defect of Consent (İrade Sakatlığı)

The will must be the free product of the testator’s mind.

• Threat (Korkutma): “Sign this or I will hurt you.”
• Fraud (Hile): Tricking the elderly person into signing a will thinking it was a utility bill.
• Error (Hata): A fundamental misunderstanding of the provisions.

3. Formal Deficiency (Şekil Eksikliği)

Turkish law is extremely strict on form.

• Holographic Will: Must be entirely handwritten, and fully dated (Day/Month/Year). If a specific date is missing or typed, it is void.
• Official Will: Two witnesses are required. If a witness was a “beneficiary” or a “close relative,” the will is invalid.

4. Illegality or Immorality

You cannot make a will that violates the law or public morality.

• Example: “I leave my house to my son only if he divorces his wife” is considered contrary to morality and family unity.

⚖️ Legal Reference: Civil Code Art. 557 “The lawsuit for annulment may be filed… if the testator lacked the capacity of disposition at the time of making the will.”

Statute of Limitations

You cannot wait forever. The lawsuit must be filed within strict deadlines (TMK Art. 559):

• 1 Year: From the date you learned about the will and the reason for invalidity.
• 10 Years: From the date of the “Opening of the Will” (statutory max).

Conclusion: The Effect of Cancellation

If the court rules for cancellation, the will is treated as if it never existed. The estate distribution reverts to the default “Legal Heirs” rules (Spouse + Children share), or a previous valid will comes into effect.
