Prenuptial Agreements in Turkey for Foreign Spouses: 2026 Strategic Guide

For foreign nationals marrying a Turkish citizen — or for international couples relocating to Turkey — a properly drafted prenuptial agreement is the single most effective instrument 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) under Articles 202 to 241 of the Turkish Civil Code (TMK), giving spouses the freedom to depart from the default property regime and select a structure that fits their financial reality.
For high-net-worth individuals, expat entrepreneurs, and binational couples, the stakes are uniquely high. Without a prenuptial agreement, every asset accumulated after marriage — including business interests, investment portfolios, and Turkish real estate — falls under the default participation in acquired property regime (edinilmiş mallara katılma), exposing capital built over a lifetime to a 50/50 division upon divorce. A well-structured prenup, executed before a Turkish notary, allows foreign spouses to protect pre-marital wealth, ring-fence inheritance, and select the property regime that aligns with their 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
Prenuptial agreements in Turkey are codified under TMK Articles 202–241 and are fully enforceable when properly executed before a Turkish notary public.
Foreign nationals may elect one of four matrimonial property regimes: separation of property, separation of property with sharing, community of property, or the default participation in acquired property.
A prenup may be signed before marriage or during the marriage; it takes effect on the marriage date or signing date respectively.
Notarisation is mandatory under TMK Article 205, and a sworn translator is required when either spouse does not speak Turkish.
A foreign prenup executed abroad may be recognised in Turkey under MÖHUK provisions, provided it complies with formal requirements and does not offend Turkish public policy.
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 by either spouse during the marriage through paid labour, investment returns, or compensation forms a common pool that is divided equally upon dissolution. Personal property — assets owned before marriage, gifts, inheritances, and personal items — remains the separate property of each spouse. 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). Most foreign nationals and HNWIs select pure separation of property because it preserves the principle that what each spouse owns remains theirs alone — eliminating the equalisation calculation that otherwise applies on divorce.
Formal Validity Requirements (TMK Article 205)
A prenuptial agreement is only valid in Turkey when it is signed and authenticated before a Turkish notary public (noter). Private agreements, even those signed before witnesses, carry no legal effect. The notary verifies the identity and legal capacity of the spouses, reads the contract aloud, and ensures both parties understand the regime they are selecting. If either spouse does not speak Turkish, a sworn translator (yeminli tercüman) must be present throughout the signing.
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 regularly drafts and negotiates prenuptial agreements for clients with assets in multiple jurisdictions, working alongside the Lexin Legal alliance to co-ordinate cross-border estate and tax planning.
Choice of Law Under MÖHUK
Article 15 of the Turkish Code on International Private and Procedural Law (MÖHUK, Law No. 5718) permits spouses to designate the law applicable to their matrimonial property regime. For binational couples, this is a decisive strategic lever. A German-Turkish couple may agree that German marital property law governs; a UK-Turkish couple may elect English law for property classification. The selected foreign law must be specified within the prenuptial contract and authenticated through the notary procedure.
Recognition of Foreign Prenuptial Agreements
A prenuptial agreement executed abroad — for example, before a New York attorney or a London solicitor — does not automatically take effect in Turkey. Turkish courts will examine whether the foreign agreement complies with the formal requirements of the law under which it was signed and whether it offends Turkish public policy (ordre public). Agreements that purport to waive child support, predetermine custody, or unconscionably impoverish one spouse are routinely refused recognition. Where Turkish-situated assets are at stake, the prudent approach is to execute a parallel Turkish-language prenup before a Turkish notary, mirroring the foreign agreement and incorporating it by reference.

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 the most 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. An asset schedule that is incomplete or imprecise is the single most common reason that otherwise valid prenups produce contested outcomes years later.
The Step-by-Step Process to Sign a Prenuptial Agreement
Step 1 — Strategic Assessment and Asset Inventory
Before drafting, both spouses — typically through independent counsel — compile a complete inventory of pre-marital assets, anticipated inheritances, business interests, and cross-border holdings. For HNWIs, this stage often involves co-ordination with tax advisors and trust counsel in multiple jurisdictions to ensure that the prenup aligns with broader estate planning. Our in-house clinical psychologist is also available where the negotiation involves sensitive dynamics between spouses, families of origin, or children from previous relationships.
Step 2 — Drafting and Choice of Regime
The prenuptial agreement is drafted by Turkish family law counsel, typically in Turkish with a parallel English translation. The contract specifies the chosen property regime, the inventory of separate assets, the treatment of income from those assets, provisions for joint property acquired during the marriage, and — for international couples — any choice-of-law election under MÖHUK Article 15.
Step 3 — Notarisation Before a Turkish Notary
Both spouses appear in person at the notary's office with valid identification (passport, residence permit, or Turkish ID). If either spouse does not speak Turkish, a sworn translator joins the meeting. The notary reads the agreement, confirms understanding, and authenticates the signatures. If signed before marriage, the prenup takes legal effect on the date of marriage registration; if signed during the marriage, it takes effect immediately upon notarisation.
Step 4 — Registration and Cross-Border Coordination
While Turkish prenuptial agreements do not require registration in a public marital property register, foreign nationals are advised to lodge certified copies with their home-country counsel and, where appropriate, with foreign courts that may later be called to recognise or enforce the contract. Apostille certification under the 1961 Hague Convention is recommended for cross-border use.
Costs, Timelines & Key Thresholds 2026
Notary fees for prenuptial agreements in Turkey are calculated as a percentage of the declared asset values disclosed in the contract, with a statutory ceiling. For a standard separation-of-property agreement listing assets in the EUR 1–5 million range, official notary fees typically fall between TRY 15,000 and TRY 60,000 in 2026. Legal drafting fees vary based on the complexity of the asset structure and the presence of cross-border elements; for HNWI matters spanning multiple jurisdictions, professional fees commonly range from EUR 3,500 to EUR 15,000.
From engagement to signed contract, the timeline is typically two to six weeks. The asset inventory and drafting phase takes one to four weeks; the notary appointment is scheduled within seven to ten days; the signing itself takes one to two hours. For couples planning to marry imminently, the entire process can be expedited to within ten business days where both parties and their counsel are aligned.
Once signed, the prenuptial agreement remains in force throughout the marriage and may only be modified or revoked by a subsequent notarised contract executed by both spouses.
Frequently Asked Questions
Are prenuptial agreements legally valid in Turkey?
Yes. Prenuptial agreements are codified under TMK Articles 202–241 and are fully enforceable when executed in compliance with TMK Article 205 — meaning they must be signed before a Turkish notary public. Private agreements, contracts signed before witnesses, or unsigned drafts carry no legal effect under Turkish law.
Can a foreign prenuptial agreement be enforced in Turkey?
Foreign prenuptial agreements may be recognised under MÖHUK provisions if they comply with the formal requirements of the law under which they were executed and do not violate Turkish public policy. However, where significant assets are located in Turkey, executing a parallel Turkish-law prenup before a Turkish notary is the safest approach to avoid recognition disputes during divorce proceedings.
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). Most foreign HNWIs and entrepreneurs choose pure separation of property for maximum asset protection.
When must a prenuptial agreement be signed?
A prenup may be signed at any point — before marriage, on the day of marriage, or during the marriage. If signed before marriage, it takes legal effect on the date of marriage registration. If signed during the marriage, it takes effect immediately upon notarisation but does not retroactively reclassify assets that were acquired before signing.
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. For maximum protection, spouses should also execute mirror agreements in jurisdictions where significant assets are located, and consider electing foreign law to govern those assets under MÖHUK Article 15.
Can a prenup waive alimony or determine child custody?
No. Provisions waiving spousal support (yoksulluk nafakası), child support (iştirak nafakası), or pre-determining child custody are unenforceable as a matter of Turkish public policy. Custody and child support are determined by the family court at the time of divorce based on the best interests of the child.
