EXECUTIVE LEGAL SUMMARY (TL;DR)

  • Under Turkish Civil Code (TMK) Article 705, ownership of real estate is legally transferred only upon official registration at the Land Registry Directorate (Tapu Müdürlüğü) — private sales agreements signed with developers or real estate agents are legally invalid to transfer title.
  • Off-plan Promise-to-Sell Agreements (Taşınmaz Satış Vaadi Sözleşmesi) must be executed before a Turkish Public Notary and annotated onto the land registry (Şerh) to protect the foreign buyer against third-party seizures or double-selling.
  • Foreign landlords seeking to evict defaulting or holdover tenants must strictly follow the mandatory mediation (Zorunlu Arabuluculuk) and formal eviction notice timelines under the Turkish Code of Obligations (TBK Art. 347–356).
  • Property owners facing municipal zoning confiscations or state expropriation (Kamulaştırma) can multiply the initial administrative offer by filing an Expropriation Value Increase or De Facto Expropriation (Kamulaştırmasız El Atma) lawsuit.

1. Why Are Private Real Estate Sales Contracts Invalid Under Turkish Law?

One of the costliest mistakes made by foreign property buyers in Istanbul, Antalya, Bodrum, and Ankara is signing an ordinary bilingual "Sales Contract" at a developer’s sales office and wiring funds without appearing before a Turkish Public Notary or the Land Registry.

Under Article 706 of the Turkish Civil Code (TMK), Article 237 of the Turkish Code of Obligations (TBK), and Article 26 of the Land Registry Law, any agreement to transfer real estate that is not executed at the Land Registry Directorate or as a Notarized Promise-to-Sell Contract is legally null and void (Kesin Hükümsüz).

Even if a buyer has paid 100% of the purchase price and received the keys, an unnotarized contract leaves the unit registered as the developer’s asset — exposing it to third-party tax liens or bankruptcy attachments unless a notarized contract is annotated (Şerh) onto TAKBİS.

2. Lawsuits Against Defaulting Developers: Forced Tapu Registration & Refunds

When a construction company delays project completion, refuses to transfer title despite payment, or delivers a defective unit (Ayıplı İfa), foreign investors have strong judicial remedies before the Turkish Consumer Courts and Civil Courts of First Instance.

Forced Title Registration (Tapu İptali ve Tescil): If you hold a notarized promise-to-sell contract (or where formal invalidity is abused in bad faith after possession), we obtain an immediate Precautionary Injunction (İhtiyati Tedbir) freezing the parcel and compel judicial registration in your name.

Purchasing-Power Refund & Lost Rent (Kira Kaybı): Alternatively, buyers exiting a stalled project can sue for full restitution adjusted to current foreign-currency and real-estate purchasing power (Denkleştirici Adalet), alongside fair market lost rental income for every month of delay.

3. How Can Foreign Landlords Lawfully Evict a Tenant in Türkiye?

Turkish residential and commercial lease law (TBK Art. 299–356) strictly protects tenants against arbitrary eviction. Merely reaching the end of a 1-year lease term does not entitle the landlord to remove a tenant without a statutory ground.

Valid eviction grounds include: a Written Eviction Undertaking (Tahliye Taahhütnamesi) signed after move-in and enforced within 1 month of the vacate date; genuine housing need of the landlord or new owner (with notary notice within 1 month of Tapu transfer); or non-payment of rent.

For unpaid rent, our firm initiates the accelerated 30-day Bailiff Eviction Procedure (Örnek No: 13 Tahliyeli İcra Takibi), while complying with Türkiye’s Mandatory Lease Mediation (Zorunlu Arabuluculuk) rules for contested eviction and rent-adaptation suits.

4. Expropriation (Kamulaştırma) & Municipal Zoning Confiscation Lawsuits

Foreign nationals and expats owning land or villas in expanding urban corridors frequently encounter state expropriation (Law No. 2942) or de facto municipal confiscation (Kamulaştırmasız El Atma), where a parcel is frozen as a park, road, or school zone for over 5 years without payment.

Our real estate litigation team challenges undervalued administrative appraisals and files De Facto Expropriation Compensation Lawsuits before the Civil and Administrative Courts to recover full current market value plus statutory interest.

Title Deed Transfer Cost & Developer Delay Penalty Calculation

Tapu Transfer Fee = 4% of Declared Sales Value (minimum municipal tax value) + Döner Sermaye Fee | Developer Delay Claim = Contractual Penalty + Fair Market Lost Rental Income (Ecrimisil / Kira Kaybı)

In Pre-Paid Housing Sales under Turkish Consumer Protection Law No. 6502 (Art. 40–46), developers cannot exceed a maximum delivery period of 36 months from the contract date.

Court of Cassation — General Assembly of Civil Chambers (Yargıtay Hukuk Genel Kurulu) — Principle Ruling on Invalid Private Real Estate Sales Contracts & Unjust Enrichment

Where a real estate sales contract is signed privately without official Tapu registration or notarized form, the contract is null and void; however, the buyer is entitled to recover all paid amounts updated to their current purchasing power (Denkleştirici Adalet İlkesi) calculated via gold, foreign currency, and CPI indices.

FREQUENTLY ASKED LEGAL QUESTIONS (FAQ)

Can I cancel a private (unnotarized) contract I signed with a developer in Türkiye and get my money back?

Yes. Because unnotarized real estate sales contracts are legally invalid under Turkish law, you can demand immediate restitution of all payments. Under Court of Cassation precedent, courts also award purchasing-power equalization (Denkleştirici Adalet) so inflation does not erode your refund.

How long does it take to evict a tenant who stops paying rent in Türkiye?

Using the specialized Bailiff Eviction Procedure (Örnek No: 13 Tahliyeli İcra Takibi), if the tenant fails to pay the full arrears within the statutory 30-day notice period, we apply directly to the Enforcement Court (İcra Hukuk Mahkemesi) for a summary eviction order, which is typically granted within 3 to 6 months.

Are there military zone restrictions for foreign buyers in Türkiye?

Foreign nationals may purchase up to 30 hectares of real estate across Türkiye outside military forbidden zones and special security zones (Law No. 2644 Art. 35). In almost all urban districts, military clearance has been automated within the TAKBİS system.
