QUICK ANSWER
The legal position in one minute
The Turkish Civil Code recognises specific grounds—adultery, attempted murder or serious abuse and degrading conduct, crime or a dishonourable life, desertion and mental illness—and the general ground that the marital union has broken down fundamentally. Uncontested divorce and divorce following failed earlier proceedings are regulated within the general-ground framework.
01
The five specific statutory grounds
Articles 161 to 165 regulate adultery; attempted murder, very serious mistreatment or gravely degrading conduct; commission of a crime or living a dishonourable life; desertion; and mental illness. Each ground has elements that must be matched to dated facts rather than stated as a conclusion.
Specific grounds can involve special preconditions, waiting periods, forfeiture or evidential issues. Desertion, for example, has a formal warning structure; mental illness requires the statutory medical and intolerability framework. The current text should be checked before filing.
- Adultery — Article 161
- Attempted murder, serious abuse or degrading conduct — Article 162
- Crime or dishonourable life — Article 163
- Desertion — Article 164
- Mental illness — Article 165
02
Breakdown of the marital union
Article 166 allows divorce where the marital union has broken down fundamentally and the spouses cannot reasonably be expected to continue their common life. The petition should identify who did what, when, where and how the event affected the marriage.
Repeated insults, violence, economic control, abandonment of family responsibilities, serious trust violations or other conduct may be relevant according to the full context. Courts assess the pleaded events, denials, lawful evidence and comparative fault; they do not decide on broad character descriptions alone.
03
Uncontested divorce is a distinct route
Under Article 166/3, a marriage lasting at least one year may end through a joint application or acceptance when both parties are heard personally and the judge approves the arrangements for financial consequences and children. The legal ground is not simply a private agreement.
If consent is withdrawn or the protocol is incomplete, the case cannot automatically continue as a completed agreed divorce. The procedural position and any alternative allegations should be considered before filing.
04
Grounds, evidence and fault must align
Every relied-on event should be connected to a lawful source: direct witness knowledge, messages in which the party lawfully participated, medical or police records, financial records, photographs or other material whose origin and integrity can be explained.
The ground for dissolving the marriage and the fault analysis for compensation or maintenance overlap but are not identical questions. Overstating allegations can weaken credibility and increase privacy or criminal-law risks if evidence was obtained unlawfully.
05
Why timing can change the available claim
Adultery and the Article 162 grounds have statutory forfeiture periods connected with learning of the event and an outer period from the act; forgiveness can also remove the right to sue on those specific grounds. Desertion has statutory timing and warning conditions.
A person facing a limitation or service issue should not wait for a website calculation. The precise knowledge date, later conduct, formal notices, overseas address and any existing case should be reviewed against official records.

- A dated chronology of every relied-on event

- Service and address records
COMMON QUESTIONS
Questions international families often ask
Is no-fault divorce available in Türkiye?
The general breakdown ground does not require one of the five specific grounds, but a contested case still requires pleaded facts and proof. Article 166/3 separately regulates agreed divorce.
Does adultery have a time limit?
Yes. Article 161 contains periods linked to knowledge and the act, and forgiveness affects the right to sue on that specific ground. Exact dates require prompt review.
Can several grounds be pleaded?
Potentially, if the factual and legal presentation is coherent. Alternative or cumulative pleading should not create contradictory versions of the same events.
Does the spouse with more fault always lose custody?
No. Custody is determined by the child's interests. Marital fault matters only insofar as the conduct is relevant to parenting, safety or the child's welfare.
