In a Turkish preliminary sales contract, how enforceable are daily delay penalties and currency-indexation clauses for foreign buyers?

Daily delay penalties in a notarial preliminary sales contract are generally enforceable under the Turkish Code of Obligations as a contractual penalty for late performance, but a court can reduce an excessive amount. Currency-denominated or foreign-currency-indexed price clauses are only valid if at least one party is a non-resident under Decree No. 32; if both parties are Turkish “residents,” the contract must be in Turkish lira and cannot be indexed to foreign currency.

Legal basis and formal requirements

A preliminary sales contract for real estate, called a promise to sell (gayrimenkul satış vaadi sözleşmesi), must be executed as a notarial deed to be valid; an ordinary private agreement is null for lack of form. Because the underlying sale of immovables requires a statutory form, the promise to conclude it must use the same strict notarial form under the Turkish Code of Obligations (Türk Borçlar Kanunu, Law No. 6098). In practice this promise is executed as a “düzenleme şeklinde noter senedi.” Once signed, it may be annotated (şerh) at the land registry under Article 26 of the Land Registry Law (Tapu Kanunu, Law No. 2644), which protects against third parties for five years from the date of annotation. [1][4]

Daily delay penalties in practice

A daily delay penalty (gecikme cezai şartı) is a contractual penalty (cezai şart) agreed for late performance, such as the seller’s failure to deliver the completed unit on the agreed date. Under Articles 179–182 of the Turkish Code of Obligations, the creditor may claim the agreed penalty without proving damage. A judge may reduce it if the amount is excessive in light of equity and the case’s circumstances. Courts look at whether the delay is attributable to the obligor and whether the clause is clear and determinable; they do not require proof of actual loss to award the sum. These rules also apply to foreign buyers because the validity of the penalty clause is governed by Turkish substantive law. [1]

Where the buyer is a consumer and the seller acts in a commercial or professional capacity, the Consumer Protection Law (Law No. 6502) and the Regulation on Prepaid Housing Sales apply alongside the Code of Obligations. Terms that create a significant imbalance to the detriment of the consumer may be deemed unfair and not binding, and the seller has statutory delivery, information and refund duties in advance-payment scenarios. Consumer law does not ban daily delay penalties in favor of the buyer, but wording that excludes the seller’s liability for delay or imposes disproportionate penalties on the consumer may be invalid. [5][6]

Currency-denominated and foreign-currency-indexed pricing

Turkey restricts the use of foreign currency and foreign-currency indexation in certain domestic contracts. Following Presidential Decision No. 85 of 13 September 2018, Decree No. 32 on the Protection of the Value of Turkish Currency and its implementing Communiqué (No. 2008-32/34) prohibit real estate sale and lease contracts between Turkish “residents” from being denominated in or indexed to foreign currency. For contracts caught by this rule, the price and all payment obligations must be stated in Turkish lira, and clauses pegging the price to USD, EUR or another currency are invalid. The Communiqué expressly covers indexation as well as denomination. [2][3]

Whether a foreign buyer can agree an FX or FX-indexed price turns on residency under Decree No. 32, not nationality. “Resident” broadly includes individuals and legal entities domiciled or established in Turkey; persons domiciled abroad are “non-resident.” If at least one party to the preliminary sales contract is a non-resident as defined by the Decree, the FX prohibition does not apply and the parties may denominate or index the price in foreign currency. If both parties are residents, any foreign-currency or foreign-currency-indexed clause is void and the price must be in Turkish lira. Verify residency carefully, as holding a Turkish residence permit or using a Turkish company can change the analysis. [2][3]

How enforceability plays out for foreign buyers

For a foreign buyer under a Turkish-law notarial preliminary sales contract, a clear and determinable daily delay penalty is generally recoverable if the seller misses the delivery date, though a court may reduce an excessive amount; the buyer need not prove actual loss. Annotating the promise at the land registry preserves priority against third parties for five years. [1][4]

FX clauses stand or fall on Decree No. 32’s residency test: a non-resident party can validly agree an FX or FX-indexed price with a resident developer, while contracts between two residents must use Turkish lira. Consumer rules may apply in either case and can strike terms that strip protections granted by Law No. 6502. [2][3][5]

Practical next steps for a foreign buyer

Before signing, confirm each party’s residency status under Decree No. 32 and decide whether a Turkish‑lira price or an FX/FX‑indexed price is legally available; have the notary record the clause in a form consistent with the Decree and Communiqué. Set the daily delay penalty at a level that reflects foreseeable delay without inviting judicial reduction, and tie it to an objective milestone such as the “use permit (iskan)” date or the notarial handover date. Ensure the promise to sell is executed as a “notarial deed (düzenleme şeklinde noter senedi)” and seek a land registry annotation (şerh) to protect your position against third parties for five years. If the seller is a professional developer and you are buying for personal use, check compliance with Law No. 6502 and the Prepaid Housing Sales Regulation. Because enforceability turns on wording and party status, get advice from a Turkish lawyer or notary before finalizing price and penalty terms.
