When Does a Court-Set Rent Apply in Turkey? Article 345 Filing and Notice Rules

Short answer: Article 345 separates the ability to bring a rent-determination action from the period in which the resulting rent binds the tenant. It provides routes based on filing at least thirty days before the new period, a timely written increase notice followed by filing within that period, or an agreed increase clause and filing by the period’s end. Establish the actual lease-year dates and complete the applicable mediation process; the rent amount remains governed by Article 344.

Separate the amount of rent from the period it can govern

A Turkish rent-determination dispute involving a residential or roofed-workplace lease involves two connected questions: what rent the court can determine and from which rental period that amount binds the tenant. Code of Obligations Article 344 addresses the substantive rent-setting framework. Article 345 addresses filing and the effect of the decision. A strong valuation case does not by itself establish the earliest date from which the resulting rent applies.

Begin with the lease, its commencement date, renewal provisions and the period for which a new amount is sought. Identify the rent actually paid and any later agreement. An owner’s reference to “this year’s rent” is insufficient when the contractual rental year does not follow the calendar year. The claim should name the relevant period and explain how its beginning and end were established.

The tenant should make the same distinction when responding. Disputing the proposed amount does not answer a separate allegation that a timely notice preserved the period’s starting date. Conversely, accepting that an increase clause exists does not establish that every sum demanded under it is lawful. The amount, period and statutory route must each be addressed.

The ability to sue at any time does not make every past period recoverable

Article 345 begins by stating that an action to determine rent can be brought at any time. The following paragraphs then regulate when the court-determined amount binds the tenant from the beginning of a new rental period. Read those parts together. The opening sentence is not a rule allowing the landlord to select any earlier period without satisfying the stated conditions.

Identify the legal effect actually requested in the pleading. A demand for a new rent from a specified renewal date should be supported by the relevant filing date, notice or contractual clause. Where the conditions for that period are disputed, the court must be able to see the chronological issue clearly. A general claim for “market rent from the earliest possible date” leaves the decisive dates unexplained.

Keep this effective-period inquiry separate from limitation of a particular money claim, calculation of arrears and enforcement of a judgment. Those issues can arise later or alongside the determination action, but Article 345 is not a universal answer to all of them. The file should identify the legal basis of each requested consequence rather than treating determination as immediate collection.

The first route is filing at least thirty days before the new period

Article 345 provides for the court-determined rent to bind from the new period’s beginning where the lawsuit is filed no later than thirty days before that beginning, within the provision’s framework. Establish the actual court-filing date from the official record. A draft petition, appointment with counsel or payment of a professional fee is not the same event as bringing the case.

Calculate the timing against the correct contractual renewal date. Review any amendment affecting commencement or the agreed term and distinguish those changes from a mere change in payment day. A bank standing order paid on the first of each month does not necessarily establish that the annual lease period also began on that date. The lease and relevant later agreements must supply the chronology.

For an overseas landlord, document preparation and representation should be organised early enough for the applicable pre-action requirements and filing. Article 345’s timing should not first be examined when the tenant receives the claim. The procedural calendar must identify the relevant renewal date, necessary preliminary process and the legal act relied on to preserve the requested effective period.

A timely written increase notice provides the second statutory route

The second paragraph also addresses a written notice from the landlord to the tenant, within the same advance period, stating that the rent will be increased. Where that condition is met and the action is brought by the end of the following new rental period, the rent determined by the court binds from that new period’s beginning. Both the notice and later filing condition require attention.

Obtain the full notice and the legally relevant delivery evidence. A record showing that a letter was prepared or posted does not necessarily establish when the communication took legal effect against the tenant. Identify the addressee, property, intended rental period and contents. The notice must be assessed as the communication contemplated by Article 345, not merely as a general expression of dissatisfaction with the current rent.

The later lawsuit must still be brought within the statutory framework for the period being claimed. A notice should not be treated as preserving an unlimited sequence of future rental years without further analysis. Record the beginning and end of the particular new period and the actual filing date. The chronology should show how the notice and action connect to that period.

An agreed increase clause has a distinct effect under Article 345

Article 345’s final paragraph addresses a contract containing a provision that the rent will increase in the new rental period. Where the action is brought by the end of that new period, the court-determined rent is effective from its beginning. This is a separate statutory route. The analysis should identify the actual clause rather than assume one exists in every standard lease.

Read the full lease and amendments, including the wording surrounding the increase provision. A statement dealing only with payment method or a future discussion does not necessarily perform the same function as an increase clause. Conversely, a clause should not be disregarded merely because the parties later disagree about the lawful amount. Its effect under Article 345 must be examined alongside the substantive limits governing the rent.

Preserve the executed version relied on. Different copies with different clauses create an evidential issue that should be resolved before presenting a confident date conclusion. Where a representative signed the lease, check the relevant authority and document history. The timing argument needs an established contractual provision, not a clause inserted into an unsigned template after the dispute arose.

Article 344 still controls the substantive assessment

For ordinary renewed rental periods, Article 344 makes rent agreements valid only up to the change in the consumer price index calculated over twelve-month averages for the preceding rental year. Where no agreement exists, judicial determination is also subject to that ceiling and must consider the premises’ condition and equity. The separate longer-term review follows the next paragraph’s framework. The fact that Article 345 permits an amount to operate from a period’s beginning does not remove the substantive rules governing that amount.

Article 344 separately addresses leases longer than five years or renewed after five years, and subsequent five-year intervals. In that framework, the court considers the specified index, the premises’ condition and comparable rents in an equitable determination. An estate agent’s proposed asking rent is therefore not the entire statutory analysis. Identify reliable comparables and explain differences in condition, location and relevant contractual characteristics.

Foreign-currency rent is addressed separately in Article 344, with the foreign-exchange legislation and the hardship provision in Article 138 expressly reserved. A contract denominated in another currency should not be treated as an ordinary domestic-currency calculation without checking those rules. This article concerns the effective-period question; the actual amount must be determined under the substantive framework applicable to the particular lease.

A lease written for more than one year does not remove the need to examine the statutory annual rent framework. Article 344 expressly extends its first-paragraph rule to contracts longer than one year. Read the contractual term, payment periods and increase clause together. The duration of the original signed contract and the rental period for which a determination is sought are related facts, but they should not be substituted for one another when preparing the Article 345 chronology.

Build one chronology that the court and tenant can verify

A useful chronology records execution, commencement, renewals, amendments, written notices, their legal delivery, mediation and filing. Link each date to the document establishing it. Separate the date printed on a notice from the date of its legally effective communication. Separate a mediation application from a court action. Those distinctions prevent a seemingly complete timeline from relying on the wrong legal events.

The payment schedule should identify the contractual rent, amounts requested, amounts paid and the periods to which each payment was allocated. Preserve bank descriptions and correspondence explaining disputed allocations. A larger payment made once should not automatically be described as a permanent agreement to every future increase. Its legal effect depends on the actual agreement and circumstances.

Where the property changed owner, provide the acquisition record and relevant lease documents. Article 310 states that the new owner becomes a party to the lease when the premises change hands, with the specified expropriation reservation. A purchase does not by itself establish a new annual lease-start date. The rent-determination chronology must be built from the continuing contractual relationship actually in force.

Include mandatory mediation in the timetable without confusing the legal events

Law No. 6325 Article 18/B makes application to mediation a precondition to rental-relationship lawsuits within its scope. Its specified enforcement-eviction exception should not be treated as an exemption for an ordinary rent-determination claim. The parties should plan the required process as part of the filing timetable and retain the final mediation record.

Article 18/A(15) addresses suspension of limitation and non-running of forfeiture periods between the mediation application and final record. That rule must be read for the period and consequence actually in issue. Do not assume without analysis that applying to mediation is identical to the court filing or written increase notice referred to in Article 345. Preserve the separate dates and establish how the rules apply to the requested effective period.

The mediation account should identify the rental period, amount sought and any disagreement about prior notice or the increase clause. If the parties settle, state the agreed amount, effective date, payment schedule and treatment of existing differences clearly. An agreement mentioning a new monthly figure without its starting period can leave the principal dispute unresolved.

Use the rent-dispute court and plead the requested period precisely

Code of Civil Procedure Article 4 assigns rental-relationship cases to the Civil Court of Peace within its stated scope. The claim should identify the correct parties, lease, property, period and requested determination, with the applicable mediation record. The procedural route is different from simply sending the tenant a revised invoice.

Present the Article 345 basis expressly: timely advance filing, timely written notice followed by filing within the relevant new period, or the contractual increase-clause route. The supporting documents should allow each element to be checked. If the parties dispute the clause or notification date, identify that issue rather than burying it in an argument about comparable properties.

The judgment must then be read for the amount and effective period actually determined. A favourable assessment of valuation evidence during the case is not itself an order changing the tenant’s rent. The parties should avoid reporting an interim procedural development as the final outcome. Keep the operative decision and its review status in the file.

Reconcile the resulting account without treating a judgment as automatic payment

Once the applicable rent and period have been established through a legally effective result, compare them with the amounts actually paid for the relevant months. The account should show the calculation transparently and credit the payments received. A demand for the gross difference without identifying the period or payment history makes the claim difficult to assess.

Distinguish the determination of rent from the procedure and conditions for collecting an alleged balance. Any interest, costs or enforcement demand requires its own legal basis and relevant dates. Article 345 should not be described as establishing every additional monetary item automatically. A payment dispute must be analysed on the actual operative result and the governing collection rules.

The rental-deposit guide concerns a separate security account. A deposit should not be silently treated as payment of an unagreed rent difference or as a universal release of the tenant’s obligations. Record the legal basis of any agreed use or return of security and keep it distinct from the rent-determination calculation.

Keep notice, authority and outcome under documentary control

For an owner abroad, identify who will approve the notice, verify its delivery, supply the lease and monitor the procedural calendar. A representative should report each material event using the corresponding document. The owner should not have to infer from a general progress message whether the notice was drafted, dispatched, legally delivered or followed by a court filing.

Property access for valuation or other necessary steps must be organised under the applicable rules. The landlord-entry guide explains notice and consideration of the tenant’s interests under Article 319. A rent dispute does not itself provide unrestricted permission to enter the premises. Keep access arrangements separate from the parties’ positions on the amount.

The final report should state the rental period assessed, the Article 345 route relied on, the rent determined or agreed, and the account actually settled. Those facts allow both parties to understand what changed and from when. The statutory timing analysis is valuable precisely because it prevents a later judgment, an earlier notice and the contract’s renewal date from being treated as the same event.

Frequently asked questions

Can a rent-determination action be filed at any time?

Article 345 says it can, but separately regulates when the resulting rent binds from a new rental period’s beginning.

What is the advance filing rule?

The provision addresses filing no later than thirty days before the new rental period starts.

Can a written notice preserve that period’s beginning?

Article 345 provides a route where the landlord gives the specified timely written notice and files by the end of the following new rental period.

Does posting a notice prove its legal delivery date?

Not necessarily. Preserve and assess the actual communication and service evidence.

What if the lease already contains an increase clause?

The final paragraph provides a distinct route for an action brought by the end of the new period, subject to the actual clause and applicable law.

Is the rental year always January to December?

No. Establish it from the lease and legally relevant amendments.

Does a five-year review guarantee the advertised market rent?

No. Article 344 requires the statutory factors and equitable assessment; asking prices are not the entire analysis.

Does a mediation application equal a court filing under Article 345?

Do not assume equivalence. Record the separate events and analyse the statutory timing consequence in issue.

Does a rent judgment prove the tenant has paid the difference?

No. Determination, account reconciliation and actual collection are distinct.

What is the key file for an overseas landlord?

Keep the executed lease, renewal chronology, complete notices and delivery evidence, mediation record, filing record, decision and payment ledger.
