Preliminary Sale Contracts in Turkey: Guide for Foreign Buyers

Many foreigners who buy property in Turkey sign a preliminary sale contract long before they ever visit a land registry office. The document — known in Turkish as a satış vaadi sözleşmesi, meaning a promise of sale — is perfectly legal and commonly used across Antalya and the rest of the country. But it comes with strict requirements, and misunderstanding them has cost buyers real money and time.

This article explains what the contract actually does, what makes it legally binding, and what you can do if the deal falls apart.

What a Preliminary Sale Contract Actually Is

A preliminary sale contract is a binding agreement in which the seller promises to sell a specific property to the buyer, and the buyer promises to purchase it at an agreed price and on agreed terms. What it is not is a transfer of ownership. Under Turkish law, ownership of real estate passes only when the sale is formally recorded at the land registry (tapu sicili). Until that moment, no matter what any contract says, the property still legally belongs to the seller.

Think of it as an agreement to agree — a firm commitment between two parties to complete a proper sale at some future date. This distinction matters enormously. If the seller becomes insolvent, accumulates debts, or simply changes their mind, a buyer holding only a preliminary sale contract is in a very different legal position from one who holds a registered title deed.

The Turkish Code of Obligations (Türk Borçlar Kanunu, Article 29) confirms that such preliminary contracts are valid in principle, but requires them to follow the same formal requirements as the main contract they will eventually produce. In the case of real estate, that means the form requirement is strict.

Why Notarisation Is Not Optional

Turkish law requires that real estate preliminary sale contracts be executed before a notary public in a specific procedure called düzenleme — which means the notary drafts the document and both parties sign it in the notary's presence. This requirement comes directly from Article 89 of the Notary Act (Noterlik Kanunu), which lists real estate preliminary sale contracts among the transactions that must be notarially drafted.

A contract signed in a developer's showroom, sent over email, or witnessed only by a private lawyer fails this test entirely. A plain written (adi yazılı) preliminary sale contract is legally void in Turkey. Turkish courts have consistently held that such documents create no enforceable obligations — the buyer has no right to demand transfer of title based on an unnotarised agreement.

This is a trap that catches many foreign buyers, particularly those purchasing off-plan apartments in Antalya. If you have not sat across from a notary public and signed a document the notary has drafted, you almost certainly do not have a valid preliminary sale contract under Turkish law.

Annotating the Contract on the Title Deed

Once you have a notarially executed preliminary sale contract, you can take a powerful protective step: ask for the contract to be annotated (şerh) on the property's title deed register. This is governed by Article 26 of the Land Register Act (Tapu Kanunu), which expressly permits notarial preliminary sale contracts to be entered in the property register at the request of either party.

The annotation transforms your personal right under the contract — which exists only between you and the seller — into a right that is effective against third parties. If the seller later sells the same property to a different buyer, or creditors seize the property, your claim survives, provided the annotation was registered before those events took place. This directly reflects the principle in Article 1009 of the Turkish Civil Code (Türk Medeni Kanunu), which gives annotated personal rights priority over later-acquired interests in the same property.

There is an important time limit, however. Under the same Article 26, the annotation remains effective for five years from the date it is entered in the register. If the sale has not been completed and the title formally transferred to you within those five years, the land registry automatically removes the annotation. So while registering the annotation is a strong protective measure, it is not a substitute for completing the purchase promptly. If you are buying through a developer or in stages, keep track of that five-year clock.

When the Seller Refuses to Complete

The most difficult situation arises when you hold a valid, notarised contract, you are ready to complete, and the seller simply refuses to appear at the land registry to sign the final transfer deed. Turkish law gives you the right to bring a forced registration action (cebri tescil davası) — a lawsuit in which you ask the court to order the land registry to transfer title to you directly, without the seller's cooperation.

This type of case is heard in civil courts (Asliye Hukuk Mahkemesi) and examined on its merits: has the preliminary contract been validly concluded? Have the conditions for completion been met? Has the buyer discharged any payment obligations? If the court is satisfied, it issues a judgment that itself substitutes for the seller's signature at the land registry.

Foreign buyers in Antalya should know that litigation takes time, and outcomes are never guaranteed. Having a lawyer review your contract before you sign — not just at the point of crisis — is by far the most effective way to avoid the courtroom.

Passing the Contract to Someone Else

One feature of the preliminary sale contract that surprises many buyers is that the promise-based right it creates can itself be transferred to a third party. The Court of Cassation (Yargıtay) has confirmed that a buyer holding rights under a preliminary sale contract may, through a separate preliminary sale contract, pass those rights to another person. This is useful in investor chains or when the original buyer needs to exit before completion.

Each link in such a chain must meet the same notarisation requirement, and the existence of multiple preliminary contracts can complicate enforcement. Good documentation and legal advice at each step are essential.

Frequently Asked Questions

Q: Is a preliminary sale contract the same as the reservation form I sign with a developer?

Not necessarily. Developers often use reservation forms, framework agreements, or construction contracts that may not meet the notarisation requirement. Unless you signed at a notary's office and the document was drafted as a düzenleme, it is likely not a binding preliminary sale contract under Turkish law. Check carefully — and consult a lawyer — before paying any significant deposit.

Q: Can I pay a deposit before the notarial contract is signed?

Technically yes, but it is risky. Money paid before the contract is notarised is not protected by a valid preliminary sale contract. If the deal falls apart and the seller refuses to refund, recovery depends on unjust enrichment law rather than contract law — a harder and slower path. Pay deposits only after the notarised contract is in place and, ideally, after the annotation has been registered on the title deed.

Q: What if the seller transfers the property to someone else before I complete?

If your contract was annotated on the title deed before the second transfer, you can enforce your prior claim against the new owner and seek court-ordered registration. If it was not annotated, your options are weaker: you can sue the seller for breach of contract and damages, but recovering the property itself becomes significantly more difficult. This is another reason not to delay the annotation step. If you are buying off-plan, consider also reviewing the risks of off-plan property purchases in Turkey.

Q: Do I need a Turkish lawyer to sign this contract?

The law only requires a notary, not a lawyer. However, a lawyer can review the draft before the notarial appointment, check whether the title deed is clean and the seller has authority to sell, and flag any clauses that might leave you exposed. In Antalya's busy property market, that pre-appointment review is often the most cost-effective legal investment a buyer can make.
