Turkish rental law is primarily governed by the Turkish Code of Obligations (Türk Borçlar Kanunu, TBK), specifically the provisions on lease contracts (TBK Articles 299–378), supplemented by the Rental Relationships Law (Kira İlişkileri Hakkında Kanun) for transitional provisions and by the Civil Procedure Code (HMK) for eviction and rent determination proceedings. The TBK's rental provisions are largely mandatory law in favor of the tenant for residential and roofed workplace leases — meaning the parties cannot contractually reduce the protections the TBK grants to tenants, even if the tenant agrees in the contract to fewer rights. This mandatory character creates a consistent pattern of landlord exposure: a lease clause that purports to give the landlord a broader termination right than the TBK permits, or a rent increase clause that exceeds the TBK's indexation ceiling, is void to the extent it conflicts with mandatory law — and a landlord who relies on a void clause faces a procedural defeat before the merits are assessed. Effective rental law representation in Turkey means building the legal position from the TBK's mandatory framework outward, not from the contract terms inward. This page sets out how we advise and represent landlords, tenants, and property investors across the main categories of Turkish rental law work.
Lease agreement drafting and review
A lawyer in Turkey advising on lease agreement drafting must explain that the TBK permits parties to freely negotiate a wide range of lease terms, but the mandatory provisions — particularly those on rent increase limitations, eviction grounds, and deposit handling — define the outer limits of what the contract can validly provide. A well-drafted lease addresses all the mandatory elements (rent amount, payment deadline and method, lease duration, deposit amount and terms) and also includes specific provisions for the areas the TBK leaves open to negotiation: maintenance and repair allocation between landlord and tenant, sub-letting restrictions, permitted use of the property, renewal mechanisms, and dispute resolution forum. For commercial leases, the parties have significantly more contractual freedom than for residential leases — many of the TBK's mandatory protections apply only to residential and roofed workplace leases, and commercial property leases for properties outside these categories can include terms that would be void in a residential context. Practice may vary by authority and year — verify current TBK mandatory provision scope for the specific lease category before finalizing any lease agreement that contains terms deviating from the TBK's default rules.
An Istanbul Law Firm advising on bilingual lease agreements for international tenants and landlords must explain that a bilingual Turkish-English lease is both a practical necessity for foreign parties and a legal precaution — because the Turkish text governs in any dispute before Turkish courts or enforcement offices, and a tenant who signed an English translation without understanding the Turkish text may face terms they did not appreciate. We draft bilingual leases where the Turkish text is the legally operative version and the English text is a translation, clearly marked as such, so that both parties understand what they are agreeing to. We also advise on the specific documentation requirements for foreign nationals renting property in Turkey (in particular, the tax identification number requirement for tenants and the mandatory bank account deposit holding obligation) and ensure these are reflected in the lease terms. Practice may vary — verify current Turkish civil registry and banking requirements for deposit account management and foreign national tenant documentation before finalizing any lease involving foreign parties.
Rent increases and the TBK indexation ceiling
A law firm in Istanbul advising on residential rent increases must explain that the TBK imposes a specific ceiling on annual rent increases for residential and roofed workplace leases — the increase cannot exceed the twelve-month average change in the Consumer Price Index (Tüketici Fiyat Endeksi, TÜFE) as published by TÜİK. A lease clause that provides for a higher increase (such as a fixed percentage above TÜFE, or a full revaluation clause) is void to the extent it exceeds the ceiling — but this does not void the entire lease or even the entire increase clause; it simply caps the enforceable increase at the TÜFE ceiling. Additionally, where a residential lease has continued for five years or more, either party can apply to court for a rent determination (kira tespiti davası) to reset the rent to the market level if the existing rent has diverged significantly from comparable market rents — and the court-set rent may be either higher or lower than what the contract currently provides. Practice may vary by authority and year — the Turkish government has periodically introduced temporary regulations modifying or capping residential rent increases beyond the standard TBK rule; verify the current applicable ceiling (TBK default, temporary government regulation, or court determination) before advising on any residential rent increase.
An English speaking lawyer in Turkey advising on commercial lease rent adjustment must explain that commercial leases (for properties that are not residential or roofed workplace leases in the TBK sense) offer significantly more contractual freedom — parties can agree to fixed increases, CPI-linked increases, revaluation clauses, or turnover-based rent structures without the TBK's residential ceiling applying. However, commercial lease rent disputes are also more complex because the freely negotiated indexation mechanism may produce disputes about how the index is calculated, which reference date applies, or whether a contractual cap on the increase was properly applied. We review commercial lease rent increase clauses for clarity and enforceability before the lease is signed, and represent landlords and tenants in commercial rent disputes where the calculation methodology is contested. Practice may vary — verify current Turkish court interpretations of commercial lease rent revaluation clause enforceability and the specific conditions under which a commercial rent determination claim can be brought before advising on any commercial rent dispute.
Eviction proceedings: grounds and procedure
A Turkish Law Firm advising on eviction must explain that Turkish law provides an exhaustive list of grounds on which a landlord can terminate a lease and seek eviction — and an eviction petition that does not specifically plead one of these statutory grounds will be dismissed regardless of how strong the factual basis for the landlord's dissatisfaction with the tenant may be. The main eviction grounds under the TBK are: (1) non-payment of rent (TBK Article 352), where the tenant has been served two valid ihtarname notices in one lease year requiring payment and has not paid; (2) breach of the tenant's contractual obligations other than rent payment; (3) expiry of a fixed-term lease without renewal, subject to the tenant's mandatory right to continue the lease beyond the agreed term in certain circumstances; (4) landlord's genuine need to use the property for personal habitation or business (ihtiyaç nedeniyle tahliye, TBK Article 350); and (5) requirement to demolish or substantially reconstruct the property. The procedural requirements for each ground differ — non-payment eviction requires a specific prior written notice (ihtar) sequence, personal use eviction requires a court action filed within a defined period after lease expiry, and contractual breach eviction requires demonstrating the specific breach. A landlord who brings an eviction claim on the wrong procedural foundation loses on procedure even if the underlying facts support eviction. Practice may vary by authority and year — verify current TBK eviction ground requirements and the specific notice and procedural prerequisites for each ground before initiating any eviction proceeding.
A lawyer in Turkey advising on the non-payment eviction procedure must explain that the double-notice (iki ihtar) rule for residential and roofed workplace leases is one of the most technically demanding eviction procedures in Turkish civil law. To establish the right to evict for non-payment, the landlord must serve two separate ihtarname notices in the same lease year on the tenant demanding payment — each notice must be properly served (either by notary or certified mail to the address specified in the lease), must demand a specific overdue amount, and must give the tenant adequate time to pay. If the tenant pays after the first notice, the first notice is extinguished. If the tenant pays after the second notice, the second notice is extinguished. Only after two un-remedied default notices in the same lease year does the landlord have the right to bring a court eviction action for non-payment. A single notice, or two notices in different lease years, does not satisfy the requirement. For squatters (tenants without a valid lease) or tenants whose fixed-term leases have expired, different procedural paths apply. Practice may vary — verify current Turkish court interpretations of the double-notice requirement and the specific notice form and service standards required for the ihtarname before commencing any non-payment eviction procedure.
Security deposits and end-of-tenancy disputes
An Istanbul Law Firm advising on security deposit management must explain that TBK imposes mandatory rules on how residential security deposits are held — the deposit cannot exceed three months' rent, and for cash deposits it must be placed in an interest-bearing bank account in the tenant's name that the landlord can only access with the tenant's written consent or a court order. A landlord who receives a cash deposit and holds it in their own account rather than the tenant's bank account has violated this mandatory rule — and the consequences include the tenant's right to demand the deposit be placed in compliance, plus potential administrative sanctions against the landlord. For non-cash security (bank guarantees, insurance policies) the holding requirements are different. In practice, many residential leases still involve informal cash deposit arrangements that do not comply strictly with the TBK — and both parties should understand the legal risk this creates before agreeing to a non-compliant arrangement. Practice may vary — verify current Turkish court approaches to non-compliant deposit arrangements and the specific bank documentation required for a TBK-compliant deposit account before advising on security deposit structures.
An law firm in Istanbul advising on end-of-tenancy disputes must explain that the most common end-of-tenancy disputes in Turkish rental practice involve two fact patterns that are often not adequately anticipated in the original lease documentation: disputes about property condition at handover (where the landlord claims damage beyond normal wear and tear and the tenant disputes the claim) and disputes about the scope of the tenant's repair obligations under the lease. The evidentiary foundation for both disputes is the property condition documentation at the start of the tenancy — a detailed handover protocol (teslim tutanağı) with photographic evidence signed by both parties at the commencement of the lease is the most effective tool for resolving end-of-tenancy condition disputes, because it establishes the baseline condition against which any alleged damage is assessed. A landlord who has no handover documentation faces an uphill evidentiary burden in claiming damage deductions from the deposit. We prepare handover protocols and advise on mid-tenancy documentation when conditions change. Practice may vary by authority and year — verify current Turkish court standards for damage evidence in deposit deduction disputes and the specific documentation standards required for successful deposit retention claims before advising on any end-of-tenancy dispute.
Commercial lease disputes and rent determination claims
An English speaking lawyer in Turkey advising on commercial lease disputes must explain that commercial lease disputes in Turkey — including rent arrears, termination disputes, and repair obligation conflicts — are heard by commercial courts of first instance (Asliye Ticaret Mahkemesi) where both parties are merchants, and by civil courts for commercial leases involving non-merchant landlords. The mandatory mediation requirement that applies to many commercial disputes applies to lease-related monetary claims as well, meaning that a monetary claim under a commercial lease must go through mandatory mediation before a court claim can be filed. For rent determination claims (kira tespiti) under long-running commercial leases where the rent has diverged from market levels, the court appoints an expert to assess current market rent comparables — and the quality of the comparable evidence submitted by each party significantly affects the expert's assessment and the court's determination. We engage rental market experts and prepare comparable evidence packages as a standard component of commercial rent determination mandates. Practice may vary — verify current mandatory mediation requirements for commercial lease monetary claims and the specific expert appointment procedures in commercial rent determination proceedings before initiating any commercial lease claim.
A best lawyer in Turkey advising on lease termination by the landlord for personal use must explain that the personal use eviction ground (ihtiyaç nedeniyle tahliye) is the most frequently litigated residential eviction ground in Turkey — and also the one where procedural failures by the landlord most often defeat otherwise meritorious claims. The requirements are: the landlord (or their spouse, or an ascendant or descendant in the first degree) must genuinely need the property for their own habitation or business; the need must be sincere and not pretextual; the eviction action must be filed within the correct time window after the lease's first expiry following the commencement of the need; and if the landlord evicts the tenant on personal use grounds and then re-lets the property within three years, the evicted tenant has a right to re-occupy and a compensation claim against the landlord. The three-year re-letting prohibition is one of the most frequently violated rules in Turkish landlord practice — because landlords often do not appreciate that winning a personal use eviction does not give them a free hand to re-let at a higher rent.

Frequently Asked Questions
- Can a residential rent increase exceed the TÜFE ceiling in Turkey? No — for residential and roofed workplace leases, the TBK caps annual rent increases at the twelve-month average TÜFE change. A lease clause providing for a higher increase is void to the extent it exceeds the ceiling. Note that the government has periodically introduced temporary modifications to this rule — verify the currently applicable ceiling before any increase.
- What is the double-notice rule for non-payment eviction? The landlord must serve two separate valid ihtarname notices demanding payment in the same lease year. Each notice must be properly served and the tenant must fail to pay after each notice. A single notice, or two notices in different lease years, does not establish the right to bring a non-payment eviction action.
- Can a landlord evict a tenant without a court order in Turkey? No — self-help eviction (locking out a tenant, removing their belongings, cutting utilities) is illegal regardless of the landlord's legal justification. All evictions require either a court enforcement order or the tenant's voluntary departure.
- What is the personal use eviction ground and what are its conditions? A landlord can seek eviction if they (or their spouse or first-degree relative) genuinely needs the property for habitation or business. The action must be filed in the correct time window after lease expiry. If the landlord re-lets the property within three years of the eviction, the former tenant has a re-occupancy right and compensation claim.
- How must a security deposit be held for a residential lease in Turkey? Cash deposits must be placed in an interest-bearing bank account in the tenant's name. The maximum deposit is three months' rent. The landlord cannot access the deposit without the tenant's written consent or a court order. A landlord who holds the deposit in their own account has violated the TBK mandatory deposit rule.
- What is a kira tespiti davası? A rent determination action brought before the civil court to reset the rent to the current market level where the existing contractual rent has diverged significantly from market comparables. Either the landlord or tenant can bring the action, and the court appoints an expert to assess current comparable rents.
- How long does a Turkish eviction proceeding typically take? Between four and twelve months for first instance proceedings, depending on the specific eviction ground, the court's calendar, and whether the tenant contests the claim. Non-payment evictions with a clear double-notice record are typically faster than contested personal use or breach claims.
- Can a landlord increase rent mid-contract? No — a landlord cannot unilaterally change the rent during the current lease term unless the increase is based on a contractually agreed and legally valid indexation clause. An unauthorized mid-term demand for higher rent does not create an obligation for the tenant.
- Is mandatory mediation required before a rental dispute goes to court? For monetary claims in commercial lease contexts, yes — mandatory mediation applies. For residential eviction proceedings, the procedure depends on the specific eviction ground. Verify the applicable mediation requirement for the specific claim type before filing.
- Can you represent both landlords and tenants? Yes — we represent both landlords in eviction, rent recovery, and lease enforcement mandates, and tenants in eviction defense, deposit recovery, and rent increase challenge mandates. Each mandate is assessed individually for conflicts before acceptance.
