Rent Determination and Rent Adjustment Lawsuits in Antalya
A dispute about the amount of rent does not always require the same legal remedy. Under Turkish law, an action for determination of rent and an action for adjustment of rent are distinct proceedings with different legal grounds, conditions and evidentiary requirements.
When I review a rent dispute in Antalya, I first determine whether the issue concerns the statutory determination of the rent under Articles 344 and 345 of the Turkish Code of Obligations, or whether an extraordinary change of circumstances may justify contractual adaptation under Article 138. The age of the lease, renewal history, existing rent clause, comparable rents, consumer price index data and the economic circumstances affecting the contractual balance must be considered together.
Quick Answer: What Is the Difference Between Rent Determination and Rent Adjustment?
A rent determination lawsuit seeks judicial determination of the rent payable for a new rental period under the statutory rules governing residential and roofed commercial leases. Article 344 regulates the criteria that may be considered, while Article 345 regulates when the action may be filed and when the judicially determined amount becomes effective.
A rent adjustment lawsuit is conceptually different. It is based primarily on Article 138 and requires an extraordinary and unforeseeable change of circumstances that fundamentally disturbs the contractual balance. Ordinary dissatisfaction with the agreed rent or routine market fluctuations do not, by themselves, establish the conditions for adaptation.
Legal Framework for Rent Determination and Rent Adjustment in Turkey
Rent disputes may arise because a contractual rent has remained substantially different from current market conditions, because the parties disagree about the amount payable for a renewed lease period, or because extraordinary circumstances have materially altered the economic balance of the contract.
Turkish law does not resolve all of these situations through a single type of lawsuit. The statutory mechanism for determining rent in residential and roofed commercial leases is principally governed by Articles 344 and 345 of the Turkish Code of Obligations. Contractual adaptation because of excessive hardship is governed separately by Article 138.
Attorney's assessment: I first classify the dispute before evaluating the amount of rent. Choosing the wrong legal basis can affect the evidence required, the relevant rental period and the legal criteria the court will apply.

What Is a Rent Determination Lawsuit in Turkey?
A rent determination lawsuit is a judicial proceeding in which the court determines the rent payable for the relevant rental period according to the statutory rules. It is particularly important in residential and roofed commercial leases where the parties cannot agree on the rent to apply in a renewed period.
The court's assessment depends substantially on how long the lease relationship has continued. A case concerning an early renewal period is not evaluated in the same way as a lease that has continued for more than five years.
A rent determination case is not simply a claim asking the court to substitute the landlord's preferred market figure for the existing rent. The court must apply the criteria prescribed by Article 344.
Who Can Seek Judicial Determination of the Rent?
Rent determination proceedings are frequently initiated by landlords seeking a judicially determined rent for a new rental period. However, the legal mechanism is not conceptually limited to landlords. A tenant may also have a legal interest in obtaining judicial determination where there is a genuine dispute concerning the rent payable under the statutory framework.
Before filing, the lease, existing rent-increase clause, commencement date, renewal periods and previous payments should be examined to determine whether a determination action is the appropriate remedy.
Why Is the Five-Year Period Important in a Rent Determination Case?
Article 344 makes an important distinction for leases that have continued for more than five years or have been renewed after five years. At that stage, the court may determine the new rent by considering several statutory factors together rather than looking only at the ordinary annual increase mechanism.
The court considers the twelve-month average change in the consumer price index, the condition of the leased property, comparable rents and principles of equity. The objective is a judicially determined rent appropriate to the particular lease and property.
Consumer Price Index
The twelve-month average CPI change remains one of the statutory factors considered by the court.
Condition of the Premises
Location, characteristics, size, use and physical condition may be relevant to the valuation.
Comparable Rents
Suitable comparable rental properties can provide important evidence of prevailing market conditions.
Equity
The court reaches its decision by considering the statutory factors and the circumstances of the individual lease.
How Does the Court Determine the Appropriate Rent?
The court does not determine market rent solely from online property advertisements or from one nearby lease. The property itself and genuinely comparable rental evidence must be evaluated together.
In practice, factors that may become relevant include the neighbourhood, exact location, property type, floor area, age, floor level, physical condition, permitted use, commercial characteristics where applicable, facilities and the dates and terms of comparable leases.
Expert examination may play an important role where the court requires a technical assessment of the property and comparable rents.
Practical review: I distinguish asking prices from evidence capable of showing an actual comparable rental relationship. A property advertised at a particular amount does not necessarily prove that the same amount represents the judicially appropriate rent for the disputed premises.
When Does a Judicially Determined Rent Become Effective?
Article 345 states that a rent determination lawsuit may be filed at any time. However, whether the amount determined by the court will bind the parties from the beginning of a particular new rental period depends on the statutory timing rules.
The New Rental Period Must Be Considered in Advance
Where the action is filed no later than thirty days before the beginning of the new rental period, the rent determined by the court may bind the tenant from the beginning of that new period.
Article 345 also contains rules concerning a written notice sent by the landlord within that period and leases containing a contractual provision for rent increases. These rules can affect how long the action may subsequently be filed while preserving effect from the beginning of the relevant rental period.
Filing a rent determination lawsuit and determining the period from which the new rent will apply are separate questions. I therefore calculate the new rental period and Article 345 timing before proceedings are started.
What Is a Rent Adjustment Lawsuit in Turkey?
A rent adjustment lawsuit seeks adaptation of the contractual rent where extraordinary circumstances arising after the contract have fundamentally disturbed the contractual balance. The principal statutory basis is Article 138 of the Turkish Code of Obligations concerning excessive hardship.
This is different from the periodic rent-determination mechanism under Article 344. A party seeking adaptation must establish circumstances satisfying the more demanding conditions of Article 138 rather than merely showing that current market rents have changed.
Important distinction: The passage of five years is central to one part of the rent-determination regime, but it is not the statutory foundation of an Article 138 adaptation claim. Adaptation depends on a fundamental and extraordinary disruption of the contractual equilibrium.
What Conditions Are Examined in a Rent Adjustment Lawsuit?
Article 138 establishes demanding conditions for judicial adaptation. The facts of the particular contract must be assessed rather than assuming that every economic change permits a rent adjustment.
- an extraordinary circumstance must arise after the contract was concluded;
- the circumstance must not have been reasonably expected from the party seeking adaptation when the contract was made;
- the circumstance must not have arisen from that party's own conduct;
- the circumstances existing when the contract was concluded must have changed substantially against that party;
- continued performance on the original terms must become contrary to good faith because of the changed circumstances;
- the statutory rules concerning performance and reservation of rights must also be considered.
Inflation, exchange-rate changes or increases in market rents should not automatically be treated as sufficient. Their legal significance depends on the contract date, duration, foreseeability, allocation of contractual risk and the magnitude of the economic change.
Rent Determination or Rent Adjustment: Which Lawsuit Is Appropriate?
Rent Determination
The focus is the statutory determination of rent for a rental period, particularly within the special rules governing residential and roofed commercial leases.
Rent Adjustment
The focus is an extraordinary post-contractual change that has fundamentally disturbed the contractual balance and created excessive hardship.
The amount by which one party wants the rent to change does not determine the legal remedy. The underlying legal reason for changing the rent must first be identified.
Is Mediation Mandatory Before a Rent Determination or Adjustment Lawsuit?
Yes. Disputes arising from rental relationships are generally subject to mandatory mediation before a lawsuit is filed under Article 18/B of the Mediation in Civil Disputes Law No. 6325, subject to the statutory exception concerning eviction through non-judgment enforcement proceedings.
Rent determination and rent adjustment lawsuits therefore require the mediation stage to be considered before court proceedings are initiated.
Mandatory mediation should not be treated merely as an administrative formality. The amount disputed, proposed rental period and parties' positions should be prepared before the mediation application.
Which Court Hears Rent Determination and Rent Adjustment Cases?
Disputes arising from rental relationships fall within the jurisdiction of the Civil Court of Peace under the Turkish Code of Civil Procedure, subject to the procedural rules applicable to the individual case.
Territorial jurisdiction should be assessed separately according to the parties, lease relationship and applicable jurisdiction rules rather than assuming that every rental dispute must automatically be filed in a particular court merely because the property is located there.
Which Documents and Evidence Are Important in a Rent Dispute?
The required evidence depends on whether the claim concerns rent determination or contractual adaptation. Commonly reviewed materials include:
- the original lease agreement and subsequent amendments;
- documents showing the commencement date and renewal history;
- rent-increase clauses contained in the lease;
- bank records and previous rent-payment history;
- written notices exchanged between landlord and tenant;
- documents from the mandatory mediation process;
- title-deed and property information;
- records concerning the size, condition, use and characteristics of the premises;
- comparable lease agreements and other reliable rental-market evidence;
- expert reports where relevant;
- economic and contractual evidence relied upon in an Article 138 adaptation claim.
Comparable rental evidence should be selected carefully. Properties in the same neighbourhood are not necessarily legally comparable if their size, age, condition, floor, use, building quality or lease dates are materially different.
How I Review a Rent Determination or Rent Adjustment File in Antalya
Review the Lease
I identify the original lease date, contractual term, parties, current rent, rent-increase clause and renewal history.
Identify the Correct Legal Remedy
I distinguish statutory rent determination under Articles 344–345 from contractual adaptation under Article 138.
Determine the Relevant Rental Period
I calculate the lease and renewal periods and identify whether the five-year regime under Article 344 is relevant.
Review Article 345 Timing
If rent determination is pursued, I assess the filing and notice dates in relation to the beginning of the new rental period.
Analyse Comparable Rents and Property Features
I review reliable comparable leases together with the condition, location and characteristics of the disputed property.
Assess Extraordinary Circumstances if Adaptation Is Claimed
For an Article 138 claim, I examine foreseeability, contractual risk, economic change and whether the original contractual balance has been fundamentally disturbed.
Prepare Mediation and Litigation Strategy
The evidence, requested rent, relevant rental period and procedural route are organised before mandatory mediation and any subsequent court proceedings.

Rent Determination and Rent Adjustment in Turkey: Frequently Asked Questions
What is a rent determination lawsuit in Turkey?
It is a lawsuit seeking judicial determination of the rent payable for the relevant rental period under Articles 344 and 345 of the Turkish Code of Obligations.
What is the difference between rent determination and rent adjustment?
Rent determination is governed principally by Articles 344 and 345 and concerns statutory determination of rent. Rent adjustment is based principally on Article 138 and concerns adaptation of a contract where extraordinary circumstances fundamentally disturb the contractual balance.
Why is five years important in a rent determination lawsuit?
For leases continuing for more than five years or renewed after five years, Article 344 permits the court to consider the twelve-month average CPI change, the condition of the property, comparable rents and equity when determining the new rent.
Can a rent determination lawsuit be filed before five years?
A rent determination action is not categorically prohibited before five years. However, the statutory criteria applied before the five-year stage differ from the broader determination regime applicable after five years.
Can a rent determination lawsuit be filed at any time?
Article 345 states that the action may be filed at any time. However, whether the judicially determined rent applies from the beginning of a particular new rental period depends on the statutory filing, notice and contractual timing rules.
What is the 30-day rule in a rent determination case?
Filing the action no later than thirty days before the beginning of the new rental period can allow the judicially determined amount to bind the tenant from the beginning of that period. Article 345 also contains related rules concerning written notice and contractual increase clauses.
Does the court only look at comparable market rents?
No. In the five-year determination regime, Article 344 requires consideration of the twelve-month average CPI change, the condition of the leased property, comparable rents and equity together.
Can inflation alone justify a rent adjustment lawsuit?
Not automatically. An Article 138 adaptation claim requires the statutory conditions concerning extraordinary and unforeseeable changes, allocation of risk, causation and excessive hardship to be evaluated in the specific contractual relationship.
Is mediation mandatory before a rent determination lawsuit?
Yes. Rental disputes such as rent determination and rent adjustment proceedings are generally subject to mandatory mediation before filing suit under Article 18/B of Law No. 6325.
Which court hears rent determination and adjustment lawsuits?
Disputes arising from rental relationships fall within the jurisdiction of the Civil Court of Peace, subject to the applicable procedural and territorial jurisdiction rules.
Are online property advertisements enough to prove market rent?
Online advertisements may provide contextual information, but the court's assessment is not based solely on asking prices. The comparability, condition and characteristics of the properties and other evidence should be considered.
Can a lawyer assist with a rent determination case in Antalya?
A lawyer can review the lease, renewal history, Article 345 timing, comparable rental evidence, mediation procedure and litigation strategy and may represent a party in the proceedings where Turkish law permits.
