Prenuptial Agreements in Turkey (2026 Guide)

Updated 8 July 2026 · By Bayraktar Attorneys

Quick answer: Turkey allows prenuptial and marital property agreements. By signing one in the required form, usually before a notary, a couple can replace the default regime with terms of their own, either before the wedding or during the marriage. It mainly governs property, not child-related duties.

A prenuptial agreement is not just for the wealthy. For international couples with assets in more than one country, it is often the simplest way to avoid uncertainty about what belongs to whom. Turkish law gives couples real freedom here, as long as the agreement is made correctly.

Why the Default Regime May Not Suit You

Without an agreement, the default regime applies, sharing the value of property acquired during the marriage. That works for many couples, but not all. If one partner brings a business, expects an inheritance, or owns property abroad, a tailored agreement can prevent disputes later. The alternatives are set out in marital property regimes.

What a Prenup Can and Cannot Do

A Turkish agreement chooses and shapes the property regime. It decides how assets are classified, owned and divided if the marriage ends. It cannot remove protections for children or waive duties the law treats as mandatory, so questions like child support stay outside its reach.

Making the Agreement Valid

Form matters. A marital property agreement generally must be made in the manner the law requires, typically before a notary, and signed by both parties with full understanding. An agreement that ignores these formalities risks being unenforceable, which defeats its purpose.

Key Points

Prenups are valid in Turkey and can be signed before or during marriage.
They mainly set the property regime, not child-related obligations.
Correct form, usually before a notary, is essential for validity.
International couples should ensure the agreement works in every relevant country.

Cross-Border Couples

If you own assets in several countries, coordinate your Turkish agreement with the rules that apply elsewhere, so it is not undone abroad. This ties closely to protecting foreign-owned assets and to the question of which law applies to your family matters.
