Commercial Lease Contains a Foreign Currency Rent Clause in Turkey: Is It Enforceable? (2026 Updated Guide)

Meta Title: Foreign Currency Rent Clause in Turkish Commercial Leases: Is It Valid? 2026

Meta Description: Can commercial rent in Turkey be agreed in USD, EUR or another foreign currency? Learn when foreign currency rent clauses are restricted, possible exceptions, payment disputes and remedies for foreign companies.

Foreign investors and international companies leasing offices, stores, factories, warehouses or other commercial premises in Turkey frequently encounter lease agreements in which the monthly rent is stated in USD, EUR or another foreign currency. Whether such a clause is enforceable cannot be answered simply by looking at the wording of the lease. Turkey maintains specific restrictions on certain foreign-currency-denominated contracts, and the result can depend on the parties, the nature of the lease, applicable exceptions and the circumstances existing when the agreement was concluded. A foreign company should therefore determine whether the lease falls within the foreign-currency restrictions before paying, demanding or litigating rent on the basis of the contractual currency.

Can Commercial Rent Be Agreed in Foreign Currency in Turkey?

Not in every case. Turkish foreign-exchange legislation restricts the use of foreign currency or foreign-currency-indexed payment obligations in specified contracts concluded between persons resident in Turkey.

Lease agreements concerning real estate located in Turkey are particularly important within this framework.

However, the legislation also contains exceptions. Therefore, the enforceability of a USD or EUR rent clause depends heavily on the legal status of the parties and the specific transaction.

Why Is the Residence Status of the Parties Important?

The foreign-exchange rules use their own concept of persons resident in Turkey. Therefore, the analysis should not be reduced simply to citizenship.

A foreign national or foreign-owned company may have a legal position different from that of a foreign company operating entirely from abroad.

The parties’ corporate and residence status should therefore be established before analyzing the currency clause.

Does Foreign Ownership of the Tenant Automatically Make the Clause Valid?

No automatic assumption should be made.

A company incorporated in Turkey may still be relevant to the Turkish foreign-exchange restriction even though all or most of its shares belong to foreign investors.

At the same time, specific exceptions may apply to certain foreign-connected parties. The precise corporate structure should therefore be reviewed.

What If the Tenant Is a Foreign Company?

The first question is whether the tenant is contracting directly as the foreign legal entity or through a Turkish subsidiary, branch or another local structure.

These arrangements should not be treated as interchangeable.

The lease should identify the actual tenant correctly.

What If Both Landlord and Tenant Are Turkish Companies?

A commercial lease denominated in foreign currency between two parties resident in Turkey requires particular scrutiny because the general restrictions may apply unless the transaction falls within a recognized exception.

Simply writing “rent shall be USD 10,000” does not override mandatory foreign-exchange legislation.

What If the Landlord Is Foreign?

The landlord’s status can materially affect the analysis. Ownership of Turkish real estate by a foreign person should not, by itself, be confused with the separate question of whether the parties fall within an exception permitting foreign-currency determination.

The actual contracting parties and their legal status must be examined.

What If the Property Is Located Outside Turkey?

A lease concerning real estate outside Turkey presents a different issue from a commercial property located in Turkey.

For Turkish commercial-property disputes, the location of the leased premises should therefore be identified at the beginning of the analysis.

Offices, Warehouses and Factories Can All Be Affected

Foreign-currency issues are not limited to residential leases.

Commercial properties potentially affected can include:

• offices;
• retail stores;
• shopping-center units;
• warehouses;
• logistics facilities;
• factories;
• production facilities; and
• other business premises.

The commercial nature of the premises does not automatically remove foreign-exchange restrictions.

What Happens If the Foreign Currency Clause Violates Mandatory Rules?

If the clause falls within a statutory restriction and no exception applies, the parties may not necessarily be able to enforce the foreign-currency payment obligation exactly as written.

The proper treatment of the rent must then be determined according to the applicable legislation, transitional rules where relevant, contractual history and facts of the case.

Does the Entire Lease Become Invalid?

Not necessarily.

A problem concerning the currency denomination of rent should be distinguished from the validity of the entire landlord-tenant relationship.

Whether the problematic clause can be separated from the remainder of the agreement requires contract-specific analysis.

Old Commercial Leases Require Special Review

Some commercial leases were signed before important foreign-currency restrictions or amendments took effect.

For an older lease, determine:

• the original execution date;
• amendments and renewals;
• whether the rent was subsequently renegotiated;
• whether the parties’ status changed; and
• how rent has actually been paid over time.

The current dispute should not be analyzed solely from the original signature page.

Renewal Agreements Can Change the Analysis

A lease may begin under one legal or factual structure and later be renewed after a corporate restructuring.

If the tenant changes from a foreign company to a Turkish subsidiary, for example, the enforceability analysis may also change.

Addenda Should Be Examined Carefully

Commercial parties often sign addenda changing only the rent.

An addendum denominating rent in USD or EUR should be reviewed together with the main lease and the mandatory rules applicable on the date of the amendment.

Foreign Currency and Foreign-Currency-Indexed Rent Are Both Important

A lease does not necessarily avoid the issue merely because rent is formally stated in Turkish lira but tied directly to a foreign currency.

Clauses providing that rent will equal the Turkish-lira equivalent of a fixed USD or EUR amount can raise similar regulatory questions.

Exchange-Rate Adjustment Clauses Need Separate Analysis

Not every clause affected by exchange-rate movements is legally identical.

The wording should be examined to determine whether the obligation is actually denominated or indexed in foreign currency or whether the contract uses another lawful rent-adjustment mechanism.

What If the Tenant Has Paid in Foreign Currency for Years?

Past voluntary performance does not necessarily settle the legal issue permanently.

However, payment history can be relevant to interpretation, calculation of outstanding amounts and the parties’ conduct.

Bank records should therefore be preserved.

Can the Tenant Suddenly Stop Paying?

A tenant who believes the foreign-currency clause is unlawful should not simply stop paying rent without analyzing the consequences.

Non-payment can trigger default allegations, enforcement proceedings and potentially eviction-related remedies.

The correct rent amount and currency should first be legally assessed.

Can the Landlord Start Enforcement Proceedings in USD or EUR?

A landlord may attempt to enforce the contractual payment obligation, but the tenant can potentially raise objections concerning the validity or enforceability of the foreign-currency clause where the applicable legislation does not permit it.

The precise defense depends on the lease, enforcement proceeding and applicable foreign-exchange rules.

Payment Orders Should Never Be Ignored

A foreign company receiving an enforcement payment order should immediately identify the applicable objection period.

Even a strong substantive defense can be seriously weakened if procedural deadlines are missed.

Can the Landlord Terminate the Lease for Underpayment?

Potentially, if legally due rent is not paid according to the applicable rules and proper default procedures are followed.

The critical question is therefore how much rent was legally due, not simply what amount appears next to the USD or EUR symbol in the contract.

Rent Calculation Can Become the Main Dispute

Where a foreign-currency clause cannot be applied as originally drafted, the parties may disagree over the lawful Turkish-lira rent.

Historical amendments, previous payments and the applicable regulatory rules may become central to the calculation.

Exchange-Rate Changes Can Produce Major Claims

A lease signed when exchange rates were substantially different may produce very large discrepancies between the parties’ positions.

Landlords may seek substantial foreign-currency arrears, while tenants may argue that the underlying clause cannot legally support those claims.

For long-term commercial leases, the financial difference can be significant.

Rent Increase Rules Must Also Be Considered

Foreign-currency restrictions and ordinary rent-increase rules are separate legal questions.

A clause may raise both currency-denomination and rent-adjustment issues.

Each should be analyzed independently.

Turnover Rent Can Create Additional Complexity

Shopping-center and retail leases sometimes combine fixed rent with turnover-based rent.

If one component is denominated in foreign currency, the enforceability of that component should be analyzed separately.

Service Charges Are Not Always the Same as Rent

Commercial leases may require payment of rent, common expenses, management charges, utilities, marketing contributions and other amounts.

The legal characterization of each payment obligation should be examined rather than assuming every amount follows the same currency treatment.

Security Deposits Should Be Reviewed

If a deposit was stated in foreign currency, determine whether the same foreign-exchange restrictions affect the deposit arrangement and how repayment should be calculated when the lease ends.

Bank Guarantees Can Raise Separate Questions

A foreign-currency bank guarantee supporting lease obligations should not automatically be treated as identical to the underlying rent clause.

The guarantee wording, underlying obligation and applicable financial rules should be reviewed separately.

Foreign Parent Guarantees Should Be Examined

International groups sometimes have a foreign parent company guarantee the Turkish subsidiary’s rent.

The guarantee may raise separate contractual and foreign-exchange issues from the lease itself.

Corporate Restructuring Can Affect Existing Leases

A merger, share acquisition or transfer of business may alter the parties involved without physically changing the premises.

Companies should review foreign-currency lease clauses during corporate due diligence rather than discovering the issue after closing.

Commercial Property Buyers Should Review Existing Leases

A foreign investor purchasing a Turkish office building, warehouse or shopping property should not assume that every USD or EUR rent stated in the rent roll is fully enforceable.

The underlying lease agreements and legal status of tenants should be examined.

This Can Affect Property Valuation

If investment value was calculated on foreign-currency rental income that cannot legally be collected in the manner assumed, the property’s expected yield may change materially.

Foreign-currency enforceability should therefore be part of commercial real estate due diligence.

Review the Lease Before Acquisition

A buyer should identify:

• rent currency;
• tenant status;
• landlord status;
• execution date;
• amendments;
• payment history;
• guarantees;
• deposits;
• rent increases; and
• pending disputes.

This is especially important where the purchase price is based on long-term rental cash flow.

What If the Parties Disagree?

The dispute may result in enforcement proceedings, rent claims, declaratory litigation, eviction proceedings or other contractual claims depending on the circumstances.

Before litigation, calculate both parties’ positions carefully and preserve payment and contractual evidence.

Keep All Bank Records

Foreign-currency lease disputes can involve years of payments.

Maintain bank transfer receipts showing currency, amount, date and payment description.

These records can become essential in calculating alleged arrears.

Preserve Negotiation Correspondence

Emails and correspondence concerning conversion of rent, exchange-rate problems, temporary discounts or amendments may help establish what the parties agreed during the lease relationship.

Do Not Sign a New Protocol Without Reviewing Its Effect

A tenant under financial pressure may be asked to sign a debt acknowledgment or payment protocol confirming USD or EUR arrears.

Such documents can materially affect later litigation.

The underlying currency issue should be reviewed before acknowledgment of the debt.

Foreign Companies Should Review Their Entire Lease Portfolio

An international group occupying multiple Turkish properties should identify every lease containing foreign-currency rent or indexation.

A portfolio-level review can prevent inconsistent treatment among subsidiaries and locations.

Renegotiation May Be Commercially Preferable

Not every dispute needs immediate litigation.

Where the legal position creates uncertainty for both sides, the parties may renegotiate the rent currency, adjustment mechanism and future payment structure.

Any amendment should comply with mandatory law.

Drafting New Commercial Leases in 2026

Before stating rent in USD, EUR or another foreign currency, determine whether the parties and transaction fall within a legally permitted exception.

The contract should not simply copy a foreign-currency clause from an international lease template.

Frequently Asked Questions

Is USD rent always prohibited in Turkish commercial leases?

No. The result depends on the parties, the property, applicable foreign-exchange rules and whether a relevant exception applies.

Can a Turkish company with foreign shareholders pay rent in euros?

Foreign ownership alone should not be treated as a complete answer. The company’s legal status and the applicable exceptions must be examined.

Is a Turkish-lira rent indexed to USD automatically valid?

Not necessarily. Foreign-currency-indexed obligations can also fall within regulatory restrictions depending on the transaction.

Does an invalid foreign-currency clause cancel the entire lease?

Not automatically. The currency clause and the continuing validity of the overall lease should be analyzed separately.

Can the tenant stop paying because the USD clause is disputed?

Stopping all rent payments can create serious default and eviction risks. The legally payable amount should first be determined.

Can the landlord demand foreign-currency arrears through enforcement proceedings?

The landlord may initiate a claim, but the tenant may have defenses if the foreign-currency obligation is legally restricted or incorrectly calculated.

Does previous payment in USD make the clause permanently enforceable?

Not necessarily. Past performance is relevant evidence but does not automatically override mandatory legal restrictions.

Should a foreign investor buying a leased property check the rent currency?

Yes. The enforceability of rental income assumptions can directly affect valuation and expected investment returns.

Can the parties convert the lease into Turkish lira voluntarily?

Potentially, subject to the applicable legal framework and contractual requirements. The amendment should clearly address the new rent amount and adjustment mechanism.

What should a foreign company do first?

Review the identity and legal status of both parties, the location and nature of the property, the date of the lease and amendments, the precise currency clause and the exception framework applicable to the transaction before deciding whether the foreign-currency rent is enforceable.
