QUICK ANSWER
The legal position in one minute
The Turkish Civil Code allows spouses or prospective spouses to choose among legally recognised matrimonial property regimes by an agreement made in the prescribed form. An agreement should be coordinated with asset ownership, inheritance, company interests, debts and any foreign marital agreement. Provisions about children, personal status or future court powers cannot simply be made binding because the parties call the document a prenuptial agreement.
01
What a Turkish matrimonial property agreement can do
The agreement can select a recognised property regime and, within statutory limits, regulate permitted aspects of that regime. The default regime and the effect of marriage dates should be identified before any change is proposed.
The document should not be treated as a substitute for title records, company agreements, wills, insurance or a complete estate plan. Each instrument has a different function.
02
Form, capacity and informed agreement
The Civil Code prescribes formal requirements for a matrimonial property agreement. Identity, capacity, authority, notarial form and any required registration or annotation should be checked through the competent institution.
Each party should understand the assets, debts and legal effect. Bilingual explanation and independent advice can reduce later disputes about mistake, pressure or misunderstanding, particularly where one spouse does not read Turkish.
03
Foreign prenups and international couples
A foreign agreement is not automatically applied in Türkiye exactly as drafted. Applicable law, formal validity, public policy, the type and location of assets and the relief sought in Turkish proceedings must be analysed under Law No. 5718.
Turkish real estate, company shares, pensions and assets abroad may require separate implementation. The couple should decide where they expect to live and where an agreement may later need recognition or enforcement.
04
A useful asset-and-risk schedule
List premarital and marital assets, valuation dates, debts, family contributions, businesses, expected inheritances, foreign property and the evidence showing their source. Use exact legal identifiers rather than informal descriptions.
The agreement should be reviewed when residence, nationality, major assets, business ownership or family circumstances change. A document written for one country and one balance sheet can become incomplete after an international move.
05
What the agreement should not promise
Parents cannot conclusively predetermine a future custody result or remove the court's responsibility for a child's interests. A waiver of every future support or remedy may also face statutory limits and judicial review depending on the issue and circumstances.
Avoid claims that a prenup guarantees a divorce outcome. Its effect must be assessed together with the applicable law, formal validity, later conduct and the specific claim before the court.
DOCUMENT PREPARATION
Documents to organise before an initial review
Do not send originals until the receiving authority and required form have been identified. Begin with legible, complete copies and retain the source, page order and verification details.
- Identity, nationality and residence records
- Marriage date or planned marriage details
- Complete asset, debt and income disclosure
- Title, company, loan and investment documents
- Existing Turkish or foreign agreements
- Estate-planning and inheritance documents requiring coordination
COMMON QUESTIONS
Questions international families often ask
Can couples sign a prenup in Türkiye?
Yes, the Civil Code permits a matrimonial property agreement in the prescribed form, including selection among legally recognised regimes.
Will a foreign prenup automatically bind a Turkish court?
Not automatically. Applicable law, form, public policy, asset location and the relief requested require analysis.
Can a prenup decide future custody?
It cannot remove the court's duty to decide according to the child's interests at the relevant time.
Does a property agreement change title ownership immediately?
Not necessarily. Selection of a property regime and transfer or registration of a particular asset are different legal acts.
