Grounds for Divorce under Turkish Law (2026)

Under Turkish law you cannot simply file for divorce because you no longer wish to be married. The court needs a legal reason, and the Turkish Civil Code sets out exactly which reasons qualify. This guide explains those grounds in plain English and points out what changes when one or both spouses are foreign nationals.

Two Categories: Specific and General Grounds

Turkish divorce law lives mainly in the Civil Code, in the articles that follow marriage. The code does not let a spouse walk away for any reason at all. Instead it lists a closed set of grounds, and every petition has to rest on at least one of them. Those grounds fall into two families. Specific grounds describe a defined event or condition, such as adultery or desertion. The general ground is broader and asks whether the marriage has broken down beyond repair. Which family your case belongs to shapes your evidence and strategy. For a wider view of the procedure, see our overview on how to get divorced in Turkey as a foreigner.

The Specific Grounds in the Civil Code

The Civil Code names five specific grounds. Each has its own requirements, and some carry strict deadlines.

• Adultery. A spouse who commits adultery gives the other a ground to divorce. The claim must be filed within six months of learning about it, and never later than five years after the event.
• Attempt on life, cruelty or serious insult. Physical violence, an attempt on a spouse's life, or gravely humiliating treatment all qualify.
• Crime or a dishonorable life. Committing a degrading offence or leading a disreputable life counts where the conduct makes shared life unbearable for the other spouse.
• Desertion. A spouse who leaves the marital home to avoid their duties, and stays away for at least six months, can be sued after a formal warning is served through the court.
• Incurable mental illness. If a spouse has a mental illness that is incurable, has lasted at least three years, and makes cohabitation intolerable, the other may divorce. An official medical board report is required.

Irretrievable Breakdown: the General Ground

Most divorces today rely on the general ground, known as the irretrievable breakdown of the marital union. The question is easy to state and harder to prove: has the marriage deteriorated so severely that the spouses can no longer be expected to live together. There is no fixed list of qualifying facts. Constant conflict, loss of trust, long separation and deep incompatibility can each support the claim. Because the standard is open, the judge weighs the evidence and each spouse's conduct. If the spouse asking for divorce is far more at fault than the other, the other spouse may object, and the court can refuse. This flexibility is why the general ground handles the majority of both contested and uncontested divorces.

Divorce by Mutual Agreement and the One-Year Rule

The friendliest route sits within the general ground. If the marriage has lasted at least one year and both spouses want out, they can divorce by mutual agreement. They either file jointly or one spouse accepts the other's petition. The couple signs a settlement covering money, property and any children, and the judge hears them in person to confirm the agreement is genuine and freely made. When the terms protect the children and neither party is pressured, the court approves it. This is the quickest path, and you can weigh it against the alternatives in our guide to divorce cost and timeline in Turkey.

Absolute Grounds, Relative Grounds and Fault

Turkish lawyers often split the grounds a second way. An absolute ground, such as proven adultery, obliges the court to grant the divorce once the fact is established; the judge does not weigh whether the marriage is otherwise workable. A relative ground, by contrast, leads to divorce only if the proven conduct has actually made the union unbearable for the claimant. Fault also travels beyond the decision to divorce. The spouse who is more at fault can be ordered to pay material and moral compensation, and heavy fault can reduce or bar a claim for alimony. So the ground you rely on can shape the financial result, not just end the marriage.

Which Law Governs the Grounds for a Foreigner's Divorce?

A Turkish court hearing a foreign couple's case does not always apply Turkish grounds. Under Turkey's private international law, the court looks first to the law of the nationality the spouses share. If they hold no common nationality, it turns to the law of their common habitual residence, and only then to Turkish law. In practice many foreign couples fall under Turkish law, but not always. If you are divorcing a Turkish citizen as a foreigner, the analysis can shift again. And if a divorce was already granted abroad, you may not need fresh grounds at all, only recognition of that foreign divorce in Turkey.

How the Ground You Choose Affects the Outcome

Selecting the right ground is a practical decision as much as a legal one. A fault-based petition can secure compensation, but it demands solid proof and usually leads to a longer, contested case. The general ground, and above all mutual agreement, trade some leverage for speed and privacy. Whichever route fits, your paperwork must be in order first; our checklist of the documents needed for divorce in Turkey shows what to prepare. Early advice on the strongest available ground is the surest way to avoid a case that stalls. For broader context on family law in Turkey, explore the rest of this guide.
