Prenuptial Agreements Turkey: Foreign Spouse Guide

For foreign nationals marrying a Turkish citizen — or for international couples relocating to Turkey — a properly drafted prenuptial agreement is one of the most effective instruments for protecting wealth, defining property rights, and avoiding disputes if the marriage ends. Turkish law recognises prenuptial agreements (commonly called evlilik sözleşmesi or mal rejimi sözleşmesi) in Articles 203 to 205 of the Turkish Civil Code (TMK): instead of the default property regime, spouses may adopt by contract one of the other regimes the Code provides (Article 202), within the limits the law sets (Article 203).

For high-net-worth individuals, expat entrepreneurs, and binational couples, the stakes are uniquely high. Without a prenuptial agreement, the default participation in acquired property regime (edinilmiş mallara katılma) applies (TMK Article 202): what each spouse acquires for consideration during the regime — earnings from work and the income of personal assets, which can include business profits and investment returns — is acquired property (Article 219), and on divorce each spouse is entitled to half of the other's surplus, the net value of that acquired property (Articles 231 and 236). Pre-marital assets and inheritances are already personal property by law (Article 220); what a well-structured prenup, executed before a Turkish notary, adds is control over income and growth during the marriage and the choice of a regime that aligns with cross-border estate planning. For a broader overview of how courts split assets when no contract exists, see our recent analysis on matrimonial property division in Turkey.

Key Takeaways

• Marriage contracts (mal rejimi sözleşmesi) are governed by TMK Articles 203 to 205: they may be made before or after the wedding and must be drawn up or certified by a notary, although the choice of regime alone can also be declared in writing when applying to marry.

• Spouses either stay in the default participation in acquired property regime or choose one of the three regimes the Code offers: separation of property, separation of property with sharing, or community of property (TMK Article 202).

• A contract may be signed before or during the marriage (TMK Article 203); if the spouses adopt a new regime during the marriage, the previous regime ends at that point (Article 225).

• Notarial form is mandatory under TMK Article 205, and under Article 74 of the Notary Law No. 1512 a sworn interpreter must be present when a party does not know Turkish.

• A contract made abroad is formally valid in Turkey if it meets the form of the place where it was made or of the law governing the regime (MÖHUK Article 7), and a foreign-law provision manifestly contrary to Turkish public policy is not applied (MÖHUK Article 5).

The Legal Framework Governing Prenuptial Agreements in Turkey

The Turkish Civil Code (TMK) establishes a comprehensive matrimonial property law system in Articles 202 through 281. The architecture distinguishes between the default property regime — which applies automatically when spouses do not sign a contract — and contractual regimes selected through a marriage contract (mal rejimi sözleşmesi). The full text of the relevant provisions is published in the official Mevzuat Bilgi Sistemi, Turkey's official legislation database.

The Default Regime: Participation in Acquired Property

Under TMK Article 202, the default regime is edinilmiş mallara katılma (participation in acquired property). Property acquired for consideration during the regime — earnings from work, payments from social security institutions, compensation for loss of working capacity, the income of personal assets and assets replacing acquired property — is acquired property (Article 219). It does not form a common pool: each spouse remains owner of his or her own assets, and on dissolution each is entitled to half of the other's surplus, meaning acquired property less the debts attached to it (Articles 231 and 236). Personal property — items for personal use, assets owned when the regime began, inheritances and other gratuitous acquisitions, and moral damages claims — remains the separate property of each spouse (Article 220), but every asset is presumed to be acquired property until the contrary is proved (Article 222). While this regime offers a degree of fairness, it exposes business owners, investors, and high-earners to substantial transfers if the marriage ends.

The Three Contractual Alternatives

Spouses may elect one of three alternative regimes set out in TMK Articles 242–281: separation of property (mal ayrılığı, Articles 242–243); separation of property with sharing (paylaşmalı mal ayrılığı, Articles 244–255); and community of property (mal ortaklığı, Articles 256–281). Pure separation of property keeps each spouse's assets apart: each retains the management, use and disposal of his or her own property (Article 242), which removes the surplus calculation that otherwise applies on divorce.

Formal Validity Requirements (TMK Article 205)

Under TMK Article 205 a marriage contract must be made as a notarial deed or with notarial certification by a Turkish notary public (noter), and it must be signed by the parties and, where necessary, their legal representatives. The one exception is the choice of regime itself, which the spouses may also declare in writing when they apply to marry. A private agreement signed only before witnesses does not meet this form. Where the notary draws up the deed, it records the parties' identities and their declaration (Notary Law, Article 84), and each party is given the deed to read and signs it if it reflects his or her wishes (Article 86). If a spouse does not know Turkish, a sworn interpreter (yeminli tercüman) must also be present (Article 74).

Strategic Considerations for Foreign Nationals

For expats and cross-border couples, prenuptial planning in Turkey involves layers that domestic Turkish couples rarely face — choice of law, asset tracing across jurisdictions, and the interaction between Turkish family courts and foreign legal systems. Our divorce and family law team drafts and negotiates prenuptial agreements for clients with assets in more than one jurisdiction, working alongside the Lexin Legal alliance to co-ordinate cross-border estate and tax planning.

Choice of Law Under MÖHUK

Article 15(1) of the Turkish Code on International Private and Procedural Law (MÖHUK, Law No. 5718) lets spouses expressly choose the law governing their matrimonial property: the law of their habitual residence at the time of the marriage, or the national law of either of them. Without a choice, their common national law at the time of the marriage applies, failing that the law of their common habitual residence at that time, and failing that Turkish law. For binational couples, this is a decisive strategic lever: a German-Turkish couple, for example, may choose German law as the national law of one spouse. Two limits matter. The choice must be made expressly, so it belongs in the notarised contract, and on liquidation immovable property is always governed by the law of the country where it is located (Article 15(2)), so Turkish real estate is liquidated under Turkish law whatever the couple chose.

Recognition of Foreign Prenuptial Agreements

A prenuptial agreement executed abroad — for example, before a New York attorney or a London solicitor — is not 'recognised' in Turkey the way a foreign judgment is; recognition under MÖHUK Article 58 concerns court decisions. The questions for a foreign contract are different: whether it met the form required by the law of the place where it was made or by the law governing the regime (MÖHUK Article 7), which law governs the regime (Article 15), and whether applying a provision of that foreign law would be manifestly contrary to Turkish public policy (ordre public, Article 5). Clauses on children or maintenance meet a further limit: under TMK Article 184(5), agreements on the ancillary consequences of divorce are not valid unless the judge approves them. Where Turkish-situated assets are at stake, the prudent approach is to execute a parallel Turkish-language contract before a Turkish notary that mirrors the foreign agreement.

Protecting Pre-Marital and Foreign Assets

For foreign spouses bringing significant wealth into the marriage — investment portfolios, equity in foreign companies, real estate held abroad, family trusts, or future inheritance expectations — a precisely drafted prenup is a reliable shield. The agreement should expressly schedule pre-marital assets, document their valuation as of the marriage date, and establish the regime governing income, appreciation, and reinvestment of those assets during the marriage. Even within the default regime, the contract can provide that assets devoted to a profession or business are personal property, and that the income of personal property does not become acquired property (TMK Article 221). An incomplete or imprecise asset schedule invites disputes years later, because every asset is presumed to be acquired property until the contrary is proved (Article 222).

Common questions about family and divorce matters in Turkey

Are prenuptial agreements legally valid in Turkey?

Yes. The Turkish Civil Code allows spouses to choose their property regime by a marriage contract made before or after the wedding (TMK Articles 202 and 203). Under Article 205 the contract must be drawn up or certified by a notary and signed by the parties; the choice of regime alone may also be declared in writing when applying to marry. A private agreement signed only before witnesses, or an unsigned draft, does not meet this form.

Can a foreign prenuptial agreement be enforced in Turkey?

A contract made abroad is formally valid if it meets the form of the place where it was made or of the law governing the regime (MÖHUK Article 7), and a provision of the foreign law that is manifestly contrary to Turkish public policy is not applied (MÖHUK Article 5). Where significant assets are located in Turkey, a parallel contract before a Turkish notary is the safer approach, not least because Turkish immovables are liquidated under Turkish law (MÖHUK Article 15(2)).

What property regimes can foreign spouses choose under Turkish law?

Spouses may select from four regimes: the default participation in acquired property (TMK Art. 202), separation of property (Art. 242–243), separation of property with sharing (Art. 244–255), or community of property (Art. 256–281). Pure separation keeps each spouse's assets apart (Art. 242).

When must a prenuptial agreement be signed?

A contract may be made before or during the marriage (TMK Art. 203), and the choice of regime can also be declared in writing at the marriage application (Art. 205). If the spouses adopt a new regime during the marriage, the previous regime ends at that point (Art. 225), so what was acquired until then is liquidated under the old regime.

Can a prenuptial agreement protect assets I own outside Turkey?

Yes. A properly drafted prenup can address foreign-held assets, including overseas real estate, foreign company shares, investment accounts, and trust interests. The choice of law under MÖHUK Article 15 applies to the regime as a whole — the law of the spouses' habitual residence at the time of the marriage or either spouse's national law — not asset by asset, and immovables are liquidated under the law of the country where they are located (Article 15(2)). Where significant assets sit in another country, take advice there as well.

Can a prenup waive alimony or determine child custody?

Not with binding effect. Under TMK Article 184(5), agreements on the ancillary consequences of divorce are not valid unless the judge approves them; in an uncontested divorce the judge must approve the arrangement on the financial consequences and the children (Article 166(3)); and on divorce the court itself regulates parental rights and contact, with the non-custodial parent contributing to the child's care and education costs according to his or her means (Article 182).
