A prenuptial agreement in Turkey is a contract that lets a couple choose how their property will be owned during the marriage and divided if it ends, instead of relying on the law’s default rules. If you marry without one, the Turkish Civil Code automatically applies the regime of participation in acquired property, which splits most assets earned during the marriage equally between the spouses. A prenuptial agreement, known in Turkish as a mal rejimi sözleşmesi, lets you keep that default or replace it with one of three alternative regimes.
This guide explains how the marriage property regimes in Turkey work, what a prenuptial agreement in Turkey can and cannot do, how the agreement is signed, and what foreign couples in particular should check. The names and procedures below are current as of the time this article is written; because rules change, confirm the points that affect you with a lawyer.
What Is a Prenuptial Agreement in Turkey?
A prenuptial agreement in Turkey is a formal contract in which spouses, or a couple about to marry, choose their matrimonial property regime under the Turkish Civil Code. Turkish law calls this a property regime agreement (mal rejimi sözleşmesi), and although people often say prenuptial agreement, the same contract can also be signed after the wedding. Its purpose is narrow but important: it sets which assets belong to each spouse and how property is shared if the marriage ends through divorce or death.
It helps to understand what the agreement does not do. A Turkish property regime agreement governs property, not personal arrangements. It cannot fix child custody in advance, cannot waive child support, and cannot decide questions the law reserves for a court at the time of divorce. Within its proper field, property ownership and division, it is binding and enforceable once signed in the required form.
The Default Regime: Participation in Acquired Property
If a couple marries in Turkey without signing an agreement, the law applies the regime of participation in acquired property (edinilmiş mallara katılma rejimi) as the default. This has been the statutory regime since the current Turkish Civil Code took effect on 1 January 2002. Under it, each spouse keeps ownership of their own assets during the marriage, but on dissolution each is entitled to a share of the value of what the other acquired while married.
The regime divides each spouse’s property into two categories, and the difference between them decides who gets what.
- Acquired property (edinilmiş mal): assets gained through effort during the marriage, such as salary and earnings from work, income from a profession or business, social security and pension payments, and income produced by personal property.
- Personal property (kişisel mal): assets that stay with the owner, such as property owned before the marriage, inheritances and gifts received during the marriage, items for strictly personal use, and compensation for non-pecuniary loss.
When the regime ends, each spouse calculates the net value of their acquired property after deducting debts. The other spouse has a participation claim (katılma alacağı) equal to half of that net value. In plain terms, the value built up by work during the marriage is shared equally, while what each spouse brought in or inherited generally stays personal. This is why many couples who want a different outcome look at a prenuptial agreement in Turkey before deciding how to hold their assets.
Marriage Property Regimes in Turkey: The Four Options
Turkish law offers one default regime and three optional regimes, and a property regime agreement is how a couple selects an option other than the default. The marriage property regimes in Turkey are set out in the Turkish Civil Code, and spouses can only choose among these defined regimes; they cannot invent a custom one.
- Participation in acquired property (the default): each spouse owns their own assets during the marriage, and on divorce each shares half the value of what the other earned while married. It suits couples who are content with the legal default.
- Separation of property (mal ayrılığı): each spouse fully owns and manages their own assets, and there is no sharing on divorce, so each keeps what is theirs. It suits couples who want clear financial independence.
- Shared separation of property (paylaşmalı mal ayrılığı): each spouse owns their own assets, but property that served the family is shared on divorce, subject to statutory rules. It suits couples who want separation with some fairness for family assets.
- Community of property (mal ortaklığı): certain assets form a joint pool the spouses own together, and that pool is divided between them on divorce. It suits couples who want most assets held jointly.
Most couples who sign an agreement choose separation of property, because it keeps each person’s finances fully their own and avoids a participation claim later. The other regimes suit narrower situations. Whichever you prefer, understanding the marriage property regimes in Turkey before you sign is the foundation of a sound decision.
How a Prenuptial Agreement in Turkey Is Made
A prenuptial agreement in Turkey must follow a strict form to be valid. The agreement has to be made before a notary (noter), who draws it up or approves it, and both spouses must have legal capacity to contract. Couples can also state their chosen regime at the time of the marriage application to the civil registry; outside that moment, the notarised form is the safe route. An agreement that ignores the required form is not enforceable, so the formalities matter as much as the content.
The timing is flexible. Spouses may sign before the wedding, in which case it functions as a classic prenuptial agreement, or at any point during the marriage, when it is often called a postnuptial agreement. A couple can also change regimes later by signing a new agreement, again before a notary. If you are wondering how does a prenuptial agreement work in Turkey in practice, the short answer is that it takes effect through this notarised form and then governs property for as long as the chosen regime lasts. In our practice at Karanfiloglu Law Firm, the smoothest cases are those where both spouses take independent advice first and bring identification and a clear list of assets to the notary appointment, so the document reflects what they actually intend.
What a Marital Property Agreement in Turkey Can and Cannot Do
A marital property agreement in Turkey can select any of the regimes the Civil Code allows and tailor certain details the law permits, but it cannot override the law’s mandatory protections. The clearest way to understand its limits is to separate what is allowed from what is not.
What it can do
- Choose separation of property, shared separation of property, or community of property instead of the default.
- Confirm that assets each spouse brings into the marriage stay personal.
- Adjust, within statutory limits, how certain shares are calculated under a chosen regime.
- Be signed before the wedding or during the marriage, and be replaced later by a new agreement.
What it cannot do
- Decide child custody or waive child support, which a court determines on the child’s best interests at the time.
- Waive spousal maintenance entitlements that the law protects.
- Create a property regime that is not one of the four defined by the Civil Code.
- Bind a spouse who did not have legal capacity or who signed under duress.
Because a marital property agreement in Turkey operates inside these boundaries, the drafting matters. A clause that tries to reach beyond property into matters the law reserves for the court will simply not take effect, while the property choices themselves remain binding.
Prenuptial Agreement for Foreigners in Turkey
A prenuptial agreement for foreigners in Turkey raises an extra question: which country’s law governs the couple’s property. Under Turkish private international law, set out in the Act on Private International Law and Procedural Law (MÖHUK), spouses can agree to apply the law of a country where one of them is habitually resident or a national. If they make no choice, the law looks to their common nationality, then their common habitual residence, and failing those, to Turkish law as the law of the place most closely connected to them.
For international couples living in Turkey, this often means Turkish law and Turkish property regimes apply unless they choose otherwise in writing. A prenuptial agreement for foreigners in Turkey can therefore do two jobs at once: select the applicable law where the rules allow, and select the property regime within that law. Couples with assets in more than one country should also consider how a Turkish agreement will be viewed abroad, since recognition depends on the other country’s rules. In our experience at Karanfiloglu Law Firm, foreign spouses who clarify both the applicable law and the regime early avoid the most difficult disputes later.
How Property Is Divided When the Marriage Ends
How property is divided on divorce in Turkey depends entirely on the regime in force at that time. Under the default participation regime, the court values each spouse’s acquired property, deducts debts, and awards each a participation claim equal to half the other’s net acquired property, while personal property stays with its owner. Under separation of property, there is no sharing at all; each spouse simply keeps what they own. The shared separation and community regimes follow their own division rules.
This is the heart of how does a prenuptial agreement work in Turkey: by fixing the regime in advance, the couple decides today how a future division will run, rather than leaving it to the default. Disputes still reach the family court when spouses disagree on values or on which assets count as personal, but the framework, the regime, is already settled. Choosing a regime knowingly is far easier than arguing over one during a divorce.
Prenuptial Agreement in Turkey: Key Takeaways
A prenuptial agreement in Turkey lets a couple choose their matrimonial property regime under the Turkish Civil Code instead of accepting the default participation in acquired property, which shares the value of marital earnings equally on divorce. The marriage property regimes in Turkey are four: the default plus separation of property, shared separation, and community of property, and a notarised agreement is how a couple selects another option. A marital property agreement in Turkey governs property only, not custody or child support, and for international families a prenuptial agreement for foreigners in Turkey can also fix which country’s law applies. Deciding the regime knowingly, before disagreements arise, is the surest way to keep a marriage’s finances clear.

Frequently Asked Questions
What is a prenuptial agreement in Turkey?
A prenuptial agreement in Turkey is a notarised contract in which a couple chooses their matrimonial property regime under the Turkish Civil Code. It sets which assets belong to each spouse and how property is shared if the marriage ends. Turkish law calls it a property regime agreement (mal rejimi sözleşmesi), and it can be signed before or during the marriage.
What happens if you marry in Turkey without a prenuptial agreement?
If you marry in Turkey without an agreement, the law applies participation in acquired property as the default regime. Each spouse keeps ownership of their own assets during the marriage, but on dissolution each has a claim to half the net value of what the other acquired through work while married. Property owned before the marriage and inheritances generally stay personal.
How does a prenuptial agreement work in Turkey?
A prenuptial agreement works in Turkey by replacing the default property regime with one the couple chooses from those the Civil Code allows. The spouses sign the agreement before a notary, selecting separation of property, shared separation, or community of property, or confirming the default. The regime in force at the time of divorce then decides how property is divided.
What are the marriage property regimes in Turkey?
The marriage property regimes in Turkey are four: participation in acquired property, which is the default, separation of property, shared separation of property, and community of property. A couple keeps the default automatically or selects one of the other three by signing a property regime agreement before a notary. They cannot create a regime outside these four.
Can a prenuptial agreement decide child custody in Turkey?
No, a prenuptial agreement in Turkey cannot decide child custody or waive child support. These are determined by a family court on the best interests of the child at the time of the dispute. A marital property agreement governs property ownership and division only, so any clause that tries to settle custody in advance has no effect.
Does a prenuptial agreement for foreigners in Turkey hold up?
A prenuptial agreement for foreigners in Turkey is valid when it follows the required notarised form and respects the applicable law rules. Under Turkish private international law, spouses can choose the law of a country connected to them, and otherwise Turkish law often applies to couples living in Turkey. Couples with assets abroad should also check how the agreement is recognised in the other country.
Can spouses change their property regime after marriage in Turkey?
Yes, spouses can change their property regime after marriage in Turkey by signing a new agreement before a notary. The change takes effect for the future, and the previous regime is wound up according to its own rules. This flexibility means a couple can move, for example, from the default participation regime to separation of property as their circumstances change.
