Purchasing an apartment from a development project often requires the buyer to make substantial payments months or even years before the property is completed. When the developer fails to deliver the property on the agreed date, the buyer may face significant financial consequences: continued rent payments, financing costs, lost rental income, accommodation expenses and uncertainty over whether the project will ever be completed.

Under Turkish law, however, a developer’s failure to deliver the property on time is not merely a commercial inconvenience. Depending on the nature of the transaction, it may constitute debtor’s default, breach of contract and, in consumer transactions, a violation of specific consumer-protection rules.

A buyer may therefore have several remedies, including demanding delivery of the property, claiming compensation for the delay, enforcing contractual penalty clauses, terminating the contract and recovering payments already made.

The appropriate remedy depends primarily on the contract, the agreed delivery date, the buyer’s legal status and the reason for the developer’s delay.

1. Is the Buyer a “Consumer” Under Turkish Law?

The first question is whether the transaction falls within the scope of Law No. 6502 on Consumer Protection.

Where an individual purchases a residential property from a professional developer or construction company for personal rather than commercial or professional purposes, the transaction will generally qualify as a consumer transaction.

This distinction is important because Turkish consumer law provides additional protection for buyers, particularly in prepaid housing sales (ön ödemeli konut satışı).

A transaction may qualify as a prepaid housing sale where the consumer pays all or part of the purchase price before the property is transferred or delivered.

On the other hand, if the purchaser acquires the property primarily for commercial purposes—for example, through a company as part of a professional property-investment activity—the special consumer-protection provisions may not apply. The dispute may then be governed principally by the Turkish Code of Obligations and, depending on the parties and transaction, commercial-law rules.

The buyer’s status must therefore be determined before deciding which claims should be pursued.

2. How Long Does a Developer Have to Deliver a Prepaid Property?

For prepaid housing transactions falling within Turkish consumer law, one of the most important statutory protections concerns the maximum delivery period.

According to the Turkish Ministry of Trade’s current consumer guidance, the legal period for transfer or delivery of prepaid housing cannot exceed 48 months from the date of the contract. However, the parties are free to agree on a shorter delivery period. If the developer promises delivery in 24 months, for example, the developer cannot simply rely on the statutory 48-month maximum and postpone delivery until the end of that period. The contractually agreed delivery date remains binding.

Accordingly, suppose a contract signed on 1 January 2025 states:

“The apartment shall be delivered no later than 1 July 2026.”

If the developer fails to perform on 1 July 2026, the relevant delay should normally be assessed by reference to the contractual deadline—not by allowing the developer an automatic additional period up to 48 months.

This is one of the most important points for buyers dealing with delayed construction projects.

3. What Does “Delivery” Actually Mean?

Developers sometimes argue that the property has been “delivered” merely because the buyer received the keys or was allowed to enter the apartment.

Under the prepaid housing rules, however, delivery has a more specific legal meaning.

The Ministry of Trade explains that delivery may take place through:

1. registration of the condominium ownership in the consumer’s name, or
2. registration of the construction servitude in the consumer’s name together with transfer of possession of the dwelling in a condition suitable for habitation.

The Ministry expressly notes that merely handing over the keys or physically allowing the consumer to enter the property does not necessarily constitute legally sufficient delivery.

This distinction can become extremely important where a developer hands over unfinished apartments without completing the title, occupancy or other contractual requirements and subsequently argues that no delay exists.

The contract, title records and actual condition of the property must therefore be examined together.

4. When Is the Developer Legally in Default?

The general rules governing delayed contractual performance are contained in the Turkish Code of Obligations No. 6098.

Article 117 provides that a debtor generally falls into default following a notice from the creditor. However, where the date of performance has already been determined by agreement, the debtor may fall into default when that date expires without the need for a separate notice.

This has significant practical consequences in property transactions.

If the contract clearly provides:

“Delivery shall take place no later than 30 September 2026,”

the expiry of that clearly agreed date may place the developer in default under the circumstances contemplated by Article 117.

Nevertheless, sending a formal notice through a notary may still be strategically advisable. It creates strong evidence that:

• the delivery deadline has expired,
• the buyer continues to demand performance,
• the buyer reserves compensation rights,
• an additional deadline has been granted where legally necessary,
• and the developer has been warned of the consequences of continued non-performance.

5. Can the Buyer Demand That the Developer Complete and Deliver the Property?

Yes.

The buyer does not necessarily have to terminate the agreement simply because the delivery date has been missed.

Under Article 125 of the Turkish Code of Obligations, where the debtor is in default, the creditor may continue to demand performance of the contractual obligation together with compensation for losses caused by the delay.

Accordingly, a buyer may potentially say:

“I still want the apartment, but I also want compensation for the losses caused by your six-month delay.”

This option is especially important where the property has substantially increased in value.

For example, assume that a buyer purchased an apartment for TRY 5 million and that its market value later increased to TRY 9 million. Terminating the agreement and recovering only the original payments may not always be economically advantageous.

The buyer may instead seek performance while simultaneously claiming losses arising from delayed delivery.

6. Can the Buyer Claim Rent or Compensation for Loss of Use?

Potentially, yes.

Article 118 of the Turkish Code of Obligations states that a debtor in default is liable for damage caused by late performance unless the debtor proves that the default occurred without fault.

Depending on the circumstances, the buyer’s damages may therefore include items such as:

• rent the buyer had to continue paying because the new home was not delivered;
• reasonable temporary accommodation expenses;
• loss of rental income if the property was intended to be rented;
• storage or relocation expenses directly resulting from the delay;
• other financial losses that can be proven to have been caused by the developer’s default.

However, compensation is not automatic simply because the property was delivered late.

The buyer must establish the damage, causal connection and legal basis of the claim.

For example, where rental loss is claimed, the market rental value of the property may need to be established through an expert examination.

The Court of Cassation’s official decision database also contains delayed-delivery disputes concerning contractual “kira tazminatı”, or rental compensation, demonstrating the practical importance of such clauses and claims in Turkish housing litigation.

7. What If the Contract Contains a Penalty for Late Delivery?

Many construction and off-plan sale contracts provide clauses such as:

“If the apartment is not delivered by the agreed date, the seller shall pay EUR 1,000 for each month of delay.”

Such provisions may constitute a contractual penalty (cezai şart), agreed compensation or another form of contractual liability depending on their wording.

The exact contractual provision should be analysed carefully.

In appropriate circumstances, a buyer may claim the contractual amount without being required to establish every component of actual rental loss in the same way as a general damages claim.

Court of Cassation decisions also demonstrate that contractual provisions described as rental compensation or penalties may form the basis of claims arising from delayed delivery.

Therefore, the delivery and penalty provisions are among the first clauses that should be examined in any developer-delay dispute.

8. Can the Buyer Terminate the Contract?

Yes, depending on the circumstances.

Under Articles 123–125 of the Turkish Code of Obligations, where one party to a reciprocal contract is in default, the other party may ordinarily grant an appropriate additional period for performance. If the debtor still does not perform, the creditor obtains further remedies.

Article 125 allows the creditor, subject to the applicable conditions, to:

continue demanding performance and delay damages;

waive performance and claim damages resulting from non-performance; or

withdraw from the contract.

Where the contract is rescinded, the parties may demand the return of performances already rendered. The buyer may therefore seek repayment of money already paid, together with other claims available under the circumstances.

Importantly, Article 124 identifies circumstances in which granting an additional period is unnecessary—for example, where granting additional time would clearly be ineffective or where timely performance was essential under the agreement.

Therefore, a termination notice should not be drafted mechanically. Whether an additional period must first be granted should be determined from the contract and facts of the particular case.

9. Can the Developer Simply Claim “Force Majeure”?

Developers frequently rely on clauses referring to:

• economic crises,
• increases in construction costs,
• difficulties obtaining materials,
• subcontractor problems,
• administrative delays,
• labour shortages,
• extraordinary events or force majeure.

The existence of such a clause does not automatically remove the developer’s liability.

The court must examine:

1. what the contract defines as force majeure;
2. whether the alleged event was genuinely outside the developer’s control;
3. whether the event actually caused the delay;
4. whether the consequences could reasonably have been prevented;
5. how long the alleged event prevented performance.

Under Article 118, a developer seeking to avoid liability for delay damages may also have to establish that it was not at fault in falling into default.

A general statement that “construction conditions were difficult” should therefore not automatically be treated as sufficient.

10. What If the Project Is Never Completed?

A substantially more serious situation arises where the project appears to have been abandoned, construction has stopped, the developer is financially distressed or there are indications of insolvency.

In such circumstances, the buyer should immediately investigate:

• current land registry ownership;
• mortgages and liens affecting the land;
• attachments and enforcement proceedings;
• construction permits;
• project financing;
• the developer’s corporate status;
• whether the property has been promised or sold to multiple persons;
• whether security exists for the prepaid housing project.

Current Turkish consumer rules require additional security mechanisms for qualifying prepaid housing projects. For projects involving 30 or more residential units, the seller must generally provide one of the legally recognised safeguards, such as building completion insurance, a bank guarantee, a progress-payment system or secured financing mechanism.

These protections may become particularly important where the developer becomes unable to complete the project.

11. What Evidence Should the Buyer Collect?

Before starting proceedings, the buyer should preserve all documents relating to the transaction.

Particularly important evidence includes:

• preliminary sale agreement or sales contract;
• annexes and technical specifications;
• agreed delivery timetable;
• payment receipts;
• bank transfer records;
• promotional brochures;
• advertisements stating completion dates;
• e-mails and WhatsApp correspondence;
• notices sent by the developer regarding delays;
• photographs and videos of construction progress;
• land registry records;
• building permits and project documents;
• notarised notices;
• documents evidencing rent or other losses caused by the delay.

The exact wording of the contract is particularly important.

A clause stating that delivery will occur “approximately in December” is legally different from a clause stating that delivery will occur “no later than 31 December 2026.”

12. Consumer Court, Mediation and Legal Proceedings

Where the purchaser qualifies as a consumer and the dispute falls within the consumer-law system, the competent judicial forum will generally be determined under Law No. 6502.

For consumer disputes that must be brought before a Consumer Court, mandatory mediation may apply before filing the lawsuit under Article 73/A, subject to statutory exceptions and the nature and value of the particular claim. The Ministry of Trade continues to identify mandatory mediation and Consumer Courts as the applicable route for disputes outside the jurisdiction of Consumer Arbitration Committees.

Because property disputes can involve not only compensation but also transfer of title, specific performance and rights directly affecting immovable property, jurisdiction and procedural requirements should be determined according to the exact relief sought.

13. Do Foreign Buyers Have the Same Rights?

Foreign nationality does not, by itself, deprive a purchaser of contractual or consumer-law remedies in Turkey.

Where Turkish law governs the transaction and the buyer satisfies the conditions for consumer status, a foreign buyer may rely on the same consumer-protection mechanisms applicable to Turkish consumers.

The buyer may therefore seek remedies such as:

• delivery of the apartment;
• enforcement of title-transfer obligations;
• compensation for delayed delivery;
• contractual penalties;
• reimbursement of payments;
• termination of the contract;
• and, where necessary, court protection.

However, the contract’s governing-law and jurisdiction clauses should still be examined, particularly in transactions marketed internationally.

What Should the Buyer Do Immediately?

A buyer facing delayed delivery should generally avoid relying solely on telephone conversations with the developer.

A sensible legal strategy usually begins by reviewing the contract and establishing the precise delivery date. The buyer should then determine whether the seller is already legally in default, calculate the losses caused by the delay and preserve evidence.

Where appropriate, a formal notice can be sent requesting delivery within a specified period and expressly reserving rights to damages, contractual penalties and termination.

If the project appears financially unstable, the land registry, mortgages, attachments and developer’s financial/legal status should be investigated immediately.

The appropriate strategy may ultimately be very different for a buyer who still wants the property and a buyer who wants to exit the project and recover their money.

Conclusion: A Late Property Delivery Can Create More Than One Legal Claim

A developer who misses an agreed delivery deadline may face considerably more than a simple obligation to finish construction.

Under Turkish law, delayed delivery can potentially allow the buyer to:

demand completion and delivery of the property,

claim compensation for the period of delay,

claim contractual rental compensation or penalties,

claim provable financial losses,

withdraw from the contract and recover payments,

or pursue other remedies depending on the nature of the transaction.

The general default provisions of Articles 117–125 of the Turkish Code of Obligations give the creditor significant remedies when contractual performance is delayed.

For consumers purchasing prepaid housing, additional protection is provided under Turkish consumer legislation, including the current 48-month statutory maximum delivery period, while any shorter delivery period expressly agreed in the contract remains binding on the developer.

For this reason, the most important documents in a delayed-delivery dispute are usually the sales contract, the promised delivery date, payment records and evidence of the buyer’s financial loss.
