What Is Divorce and What Are the Grounds?

The Turkish Civil Code does not define divorce. Ending a validly concluded marriage during the spouses’ lifetime requires a court judgment based on the grounds and conditions set by law. Divorce may therefore be described as the legal termination of the marital union. In the Code’s system, grounds are special or general; by effect they are absolute or relative. This article lists them by those criteria; we will examine each in detail later. In an Ankara family-court file, which ground is chosen shapes the proof strategy from the start.

Under Law No. 4721, absolute grounds include adultery (Art. 161), attempt on life (Art. 162), extremely bad or honour-injuring conduct (Art. 162), desertion (Art. 164), consensual divorce (Art. 166/III) and divorce after de facto separation (Art. 166/IV). Where the material fact (adultery, crime, etc.) is proved in a suit by the faultless spouse, the court grants divorce without examining whether the union was shaken to its foundations—that effect is presumed. • Adultery (TCC Art. 161) • Attempt on life (TCC Art. 162) • Extremely bad or honour-injuring conduct (TCC Art. 162) • Desertion (TCC Art. 164) • Consensual divorce (TCC Art. 166/III) • De facto separation (TCC Art. 166/IV)

Relative grounds are: committing a crime (Art. 163), leading a dishonourable life (Art. 163), mental illness (Art. 165) and breakdown of the marital union (Art. 166/I–II). Relative grounds are discretionary: divorce may be granted only if the union is shaken to a degree that cannot reasonably be expected of the spouses. • Committing a crime (TCC Art. 163) • Leading a dishonourable life (TCC Art. 163) • Mental illness (TCC Art. 165) • Breakdown of the marital union (TCC Art. 166/I–II)

Special grounds: adultery, attempt on life, extremely bad or honour-injuring conduct, crime, dishonourable life, desertion and mental illness (Arts. 161–165). General grounds: breakdown of the union (Art. 166/I–II), consensual divorce (Art. 166/III) and de facto separation (Art. 166/IV).

Adultery is not a crime under the Penal Code but is an absolute divorce ground under the Civil Code. TCC Art. 161: if one spouse commits adultery, the other may sue for divorce. Absolute means divorce may follow once adultery is proved, without seeking further fault. Time bars: the right to sue expires six months after the entitled spouse learns of the ground and, in any event, five years after the act. A forgiving spouse has no right of action. The Code does not define adultery. It ceased to be a criminal offence in 2005; today its divorce role rests on the fidelity duty in TCC Art. 185. Tradition often requires ordinary consummation between opposite sexes for proof. Other sexual or non-sexual acts contrary to fidelity should be assessed under the general ground in Art. 166/1.

Spouses must jointly secure the happiness of the union (TCC Art. 185). Attempt on life, extremely bad treatment or honour-injuring conduct is incompatible with that duty. The victim may also sue under Art. 166 for breakdown; if conduct is systematic, using the absolute ground in Art. 162 is preferable. Art. 162 allows suit where the other spouse attempts the petitioner’s life, treats them extremely badly or engages in grossly honour-injuring behaviour. Each limb has different elements. A single incident of serious violence or threat can suffice. The Court of Cassation has treated knife threats and physical violence as Art. 162 grounds; ongoing physical violence as extremely bad and honour-injuring; exposing a spouse’s faults or insults as honour-injuring—including adultery as honour-injuring in character.

TCC Art. 163: if a spouse commits a degrading crime or leads a dishonourable life so that cohabitation cannot be expected of the other, that spouse may always sue for divorce. Desertion is a special ground with strict formal conditions. Under Art. 164 it applies where one spouse abandons the other to avoid marital duties or fails without just cause to return to the common home. Missing form or time conditions can defeat the claim. In Ankara, choosing the ground, the burden of proof and limitation periods shape the file. At Karınca Law Firm in Çankaya we advise correct ground selection and petition strategy under Arts. 161–166; later articles will cover each ground in depth. • Absolute grounds: proving the material fact is enough • Relative grounds: breakdown must also be shown • Adultery: 6-month / 5-year bars • Desertion has strict formal conditions • Ground choice drives proof strategy
