Turkish insurance law is primarily codified in two parallel frameworks: the insurance provisions of the Turkish Commercial Code (Türk Ticaret Kanunu, Law No. 6102, TTK Articles 1401–1520), which establishes the substantive rules governing insurance contracts, insurer obligations, policyholder duties, and claims procedures; and the Insurance Law (Sigortacılık Kanunu, Law No. 5684), which establishes the regulatory framework for the insurance market — governing the licensing of insurers, brokers, agents, and actuaries, and empowering the Insurance and Private Pension Regulation and Supervision Agency (Sigorta ve Emeklilik Düzenleme ve Denetleme Kurumu, SEDDK) to issue binding regulations on policy terms, solvency, and market conduct. For each insurance category — property, liability, motor, life, health, marine, and specialty lines — SEDDK has issued specific general conditions (genel şartlar) that constitute mandatory minimum standards incorporated into every policy of that type, regardless of what the individual policy document says. A policy provision that conflicts with the applicable SEDDK general conditions is void to the extent of the conflict. The SEDDK general conditions are accessible at seddk.gov.tr. This page sets out how we advise and represent policyholders, insurers, brokers, and reinsurers across the main categories of Turkish insurance law work.
Insurance policy structure and mandatory conditions
A lawyer in Turkey advising on insurance policy interpretation must explain that every Turkish insurance policy consists of three layers: the TTK's mandatory rules, which apply by operation of law regardless of what the policy says; the SEDDK general conditions for the relevant policy category, which establish the minimum terms the policy must contain; and the specific policy terms agreed between the insurer and the policyholder, which may improve upon the general conditions for the policyholder's benefit but may not reduce them. In practice, disputes about policy coverage most frequently arise at the interface between the specific policy terms and the mandatory minimum conditions — where an insurer has included an exclusion or a condition in the specific policy terms that either conflicts with the general conditions (rendering it void) or is valid but was not clearly communicated to the policyholder at inception (potentially reducing its enforceability). The TTK imposes specific duties on insurers to draw policyholders' attention to unusual or onerous terms in their policies — a failure to do so can affect the enforceability of the term in a coverage dispute. Practice may vary by authority and year — verify current SEDDK general conditions for the specific policy category and current Turkish court interpretations of the insurer's duty to draw attention to unusual terms before advising on the enforceability of any specific policy exclusion or condition.
An Istanbul Law Firm advising on the duty of disclosure obligations must explain that Turkish insurance law imposes a material disclosure obligation (beyan yükümlülüğü) on policyholders — the obligation to honestly disclose all material facts known to the policyholder that would influence a reasonable insurer's decision to accept the risk or to set the premium. A breach of the disclosure obligation — whether intentional or negligent — gives the insurer specific remedies under TTK: if the breach was fraudulent, the insurer can rescind the policy and retain the premium; if negligent, the insurer may be entitled to adjust the claim payment in proportion to the difference between the premium charged and what would have been charged for the correctly disclosed risk. Insurers frequently rely on alleged disclosure breaches to reduce or deny claims, and the validity of these reliance arguments depends on what the policy application specifically asked, whether the undisclosed fact was genuinely material, and whether the insurer's underwriting assessment would actually have changed. We challenge insurer reliance on disclosure breach defenses where the alleged non-disclosure does not meet the TTK's materiality threshold. Practice may vary — verify current Turkish court interpretations of materiality in insurance disclosure breach claims and the specific remedies available for negligent versus fraudulent non-disclosure before advising on any disclosure-based coverage dispute.
Insurance claims process and notification obligations
A law firm in Istanbul advising on the insurance claims process must explain that Turkish insurance law imposes specific notification obligations on policyholders following an insured event — and failure to comply with the notification timeline can affect the enforceability of the claim, though not necessarily void it entirely. Under the TTK and SEDDK general conditions, policyholders must notify the insurer of an insured event within a defined period (which varies by policy category — typically five working days for property and casualty lines, and longer for liability claims where damage may not be immediately apparent). The notification must be in writing and must describe the nature and extent of the insured event with sufficient specificity for the insurer to begin its assessment. A delayed notification that the insurer can show caused it actual prejudice — for example, by preventing it from preserving evidence or inspecting the loss scene — may reduce the claim payment proportionally. A delayed notification that caused no actual prejudice to the insurer is generally not a valid ground for outright denial under current Turkish court interpretations. Practice may vary by authority and year — verify current Turkish court standards for the nexus between notification delay and claim reduction and the specific notification timelines in the SEDDK general conditions for the relevant policy category before advising any policyholder on notification compliance.
An English speaking lawyer in Turkey advising on the insurer's claims assessment obligations must explain that TTK and SEDDK general conditions impose corresponding obligations on insurers — the insurer must assess a claim and communicate its decision within defined periods following receipt of complete claim documentation. Where the insurer requires additional documentation, it must specifically request the missing information within the required period; it cannot indefinitely delay the claim assessment on the pretext that the documentation is incomplete without specifying what is missing. An insurer that fails to communicate its coverage decision within the regulatory period may be in default (temerrüt), creating liability for statutory default interest (temerrüt faizi) on the outstanding claim amount from the expiry of the assessment period. We calculate the default interest exposure on delayed claims as a standard step in claim litigation preparation, because this interest component is frequently recoverable and creates additional settlement incentive for non-responsive insurers. Practice may vary — verify current SEDDK general conditions assessment period requirements for the specific policy category and current Turkish court default interest calculation methodology before quantifying the interest claim in an insurance dispute.
Denial defense and coverage dispute litigation
A Turkish Law Firm advising on insurance denial defense must explain that an insurer's coverage denial triggers a specific procedural path under Turkish law: the policyholder should first send a formal written objection (itiraz) to the insurer identifying the specific basis for disagreement, then — if the insurer maintains its denial — either refer the dispute to the Insurance Arbitration Commission (Sigorta Tahkim Komisyonu) for claims up to the applicable monetary threshold, or file a civil lawsuit in the competent commercial court (which retains jurisdiction for all insurance disputes regardless of the arbitration commission threshold if the policyholder prefers court proceedings). The Insurance Arbitration Commission is a specialized alternative dispute resolution body established under the SEDDK framework that provides faster and less costly resolution for lower-value insurance disputes — awards are issued within defined timeframes and are enforceable as court judgments. For higher-value or more complex coverage disputes, civil court litigation with expert opinion (bilirkişi) support is typically more appropriate. Practice may vary by authority and year — verify current Insurance Arbitration Commission monetary thresholds and procedural rules before advising any policyholder on the appropriate dispute resolution forum for their specific claim amount and dispute type.
A lawyer in Turkey advising on the most common insurer denial grounds and their legal validity must explain that Turkish insurers most frequently deny or reduce claims on the basis of: alleged non-disclosure of material facts at inception; alleged violation of the policyholder's claims cooperation obligations (for example, failure to allow the insurer's loss adjuster to inspect the loss scene promptly); alleged misrepresentation in the claim submission; application of policy exclusions that the insurer asserts cover the claimed event; and limitation of liability arguments based on sub-limits or deductibles. Each of these denial grounds has specific legal requirements for validity under the TTK and SEDDK general conditions — and in many cases, an insurer's denial is legally defective even if the ground is theoretically available. We assess each denial basis against the applicable legal standard before recommending the appropriate challenge approach. The commercial litigation Turkey framework — covering dispute resolution in Turkish commercial courts — is analyzed in the resource on commercial litigation Turkey. Practice may vary — verify current Turkish court standards for each denial basis and the current Insurance Arbitration Commission approach to common exclusion disputes before developing the challenge strategy.
Motor insurance: compulsory liability and CASCO
An Istanbul Law Firm advising on motor insurance law must explain that Turkish motor insurance operates through two distinct products with different legal frameworks. Compulsory traffic insurance (Zorunlu Mali Sorumluluk Sigortası, ZMSS — commonly known as traffic insurance or sigorta) is mandatory for all motor vehicles in Turkey and provides third-party liability coverage for bodily injury and property damage caused by the insured vehicle. The ZMSS is governed by specific SEDDK general conditions and covers up to defined statutory limits — limits that are periodically adjusted by SEDDK and that have historically been insufficient for serious injury claims, creating important litigation issues about excess liability. CASCO insurance (Kasko Sigortası) is optional comprehensive own-damage coverage for the policyholder's own vehicle. ZMSS claims must be submitted to the at-fault vehicle's insurer within defined periods; CASCO claims must be submitted to the policyholder's own insurer. Practice may vary by authority and year — verify current SEDDK ZMSS coverage limits and CASCO general condition requirements before advising on any motor insurance claim or denial.
An English speaking lawyer in Turkey advising on motor insurance claim disputes must explain that Turkish motor insurance litigation is among the highest-volume categories of Turkish insurance court proceedings, driven by the frequency of disputes about fault allocation, vehicle damage valuation, bodily injury compensation quantum, and the application of ZMSS coverage limits to serious injury claims. A key feature of Turkish motor insurance litigation is the role of the Güvence Hesabı (Security Account) — a statutory fund managed by the Turkish Motor Insurance Bureau that covers bodily injury and death claims from traffic accidents where the at-fault vehicle is uninsured, the at-fault driver is unidentified, or the insurer has become insolvent. Claimants with valid Güvence Hesabı claims can pursue the fund directly through standard civil court proceedings. We represent both claimants and insurers in motor insurance disputes across all stages — from initial claim submission through trial and appeal. Practice may vary — verify current Güvence Hesabı coverage categories and the specific procedural requirements for filing claims against the fund before advising any claimant on their options where the at-fault vehicle is uninsured.
Subrogation, reinsurance, and insurer-side representation
A law firm in Istanbul advising on subrogation rights (rücu hakkı) must explain that TTK Article 1472 grants an insurer that has paid a claim to the insured a statutory right of subrogation — the right to step into the insured's shoes and pursue the claim against the third party responsible for the loss up to the amount of the indemnity paid. The subrogation right arises automatically by operation of law upon payment and does not require assignment from the insured. Subrogation is most commonly pursued by insurers in property damage claims (where a fire or water damage was caused by a negligent third party), in cargo insurance claims (where carrier negligence caused the damage), and in motor insurance claims (where the at-fault driver was a third party not covered under the insurer's policy). The limitation period for subrogation claims follows the limitation period applicable to the underlying tort or contract claim against the responsible third party — not the policy's own prescription period. Practice may vary by authority and year — verify current Turkish court interpretations of subrogation scope in the specific claim category and the applicable limitation period for the underlying third-party liability before initiating any subrogation recovery action.
A Turkish Law Firm advising on reinsurance arrangements must explain that reinsurance contracts in Turkey must comply with both the TTK's provisions on reinsurance and SEDDK's reinsurance reporting and cession requirements for primary insurers. Primary insurers are required to maintain prescribed reinsurance arrangements as part of their solvency framework, and SEDDK imposes reporting obligations on reinsurance cession structures. For international reinsurance arrangements — where the reinsurer is a foreign entity — the Turkish primary insurer must ensure that the reinsurance program meets SEDDK's requirements for qualifying reinsurance, including criteria relating to the financial strength ratings of the reinsurers and the structure of the retrocession chain. Disputes under reinsurance contracts typically arise in the context of claims aggregation, follow-the-settlements provisions, and cedant's facultative or treaty conditions — disputes that are usually resolved through the arbitration mechanisms specified in the reinsurance contract rather than in Turkish courts. We advise both Turkish primary insurers on reinsurance program structure and foreign reinsurers on their Turkish market obligations. Practice may vary — verify current SEDDK reinsurance reporting requirements and qualifying reinsurer criteria before advising on any reinsurance program structure for a Turkish primary insurer.
SEDDK regulatory compliance and licensing
An English speaking lawyer in Turkey advising on SEDDK regulatory compliance must explain that all entities operating in the Turkish insurance market — insurance companies, reinsurance companies, brokers (sigortacılık brokerleri), agents (acenteler), actuaries, and loss adjusters — require specific licenses or authorizations from SEDDK, and must comply with ongoing regulatory obligations including periodic reporting, solvency capital requirements (based on a Solvency II-aligned framework that Turkey has been implementing progressively), product filing requirements, and consumer protection standards. A foreign insurer seeking to operate in the Turkish market can do so either by establishing a Turkish subsidiary (a Turkish company licensed as an insurer) or by establishing a branch of the foreign company — both approaches require SEDDK licensing and are subject to ongoing Turkish regulatory oversight. The specific capital requirements, governance standards, and reporting obligations differ between the subsidiary and branch structures. Practice may vary by authority and year — verify current SEDDK licensing requirements for each entity type, current minimum capital requirements for different insurance categories, and the specific Solvency II implementation timeline status before advising on any market entry or compliance strategy for the Turkish insurance sector.
A best lawyer in Turkey managing an insurance regulatory mandate must explain that SEDDK's supervisory approach has become increasingly active in recent years — the agency conducts on-site inspections of licensed entities, requires remediation plans for identified deficiencies, and has authority to impose administrative fines, suspend licenses, and — in serious cases — initiate criminal referrals for conduct that constitutes an offense under the Insurance Law. For insurers, brokers, and agents facing SEDDK inspections or investigations, the procedural response is important: the regulatory response to an inspection finding must be submitted within the period specified by SEDDK, must specifically address each identified deficiency, and must include a realistic and implementable remediation timeline. A generic or inadequately specific response can result in escalated enforcement action even where the underlying compliance issue is addressable. The Istanbul Bar Association at istanbulbarosu.org.tr provides resources for identifying qualified practitioners. Practice may vary — check current guidance from SEDDK before acting on any regulatory compliance analysis, as regulatory requirements evolve.
Frequently Asked Questions
- What is SEDDK and what does it regulate? SEDDK (Sigorta ve Emeklilik Düzenleme ve Denetleme Kurumu) is the Insurance and Private Pension Regulation and Supervision Agency — the Turkish financial regulator for the insurance sector. It licenses insurers, brokers, agents, and actuaries; issues mandatory general conditions for each policy category; sets solvency and capital requirements; and supervises market conduct.
- Are SEDDK general conditions mandatory? Yes — SEDDK general conditions for each policy category are incorporated into every Turkish insurance policy by operation of law. A policy provision that conflicts with the applicable general conditions is void to the extent of the conflict, regardless of what the policy document says.
- How long do I have to notify my insurer after an insured event? Notification timelines vary by policy category — typically five working days for property and casualty lines under current SEDDK general conditions. Practice may vary — verify the specific notification deadline in the SEDDK general conditions for your policy type before acting.
- Can an insurer deny a claim for late notification? Only if the late notification caused the insurer actual prejudice — for example, preventing timely loss inspection. A late notification that caused no actual prejudice to the insurer is generally not a valid ground for outright denial under current Turkish court interpretations.
- What is the Insurance Arbitration Commission? The Sigorta Tahkim Komisyonu is a specialized dispute resolution body under SEDDK for insurance claims up to defined monetary thresholds. It provides faster and less costly resolution than civil court proceedings, with awards enforceable as court judgments.
- What is compulsory traffic insurance (ZMSS) in Turkey? ZMSS is mandatory third-party liability insurance for all motor vehicles in Turkey. It covers bodily injury and property damage caused to third parties up to SEDDK-defined statutory limits. It is distinct from voluntary CASCO insurance, which covers own-vehicle damage.
- What is the Güvence Hesabı? The Security Account is a statutory compensation fund that covers bodily injury and death claims from traffic accidents where the at-fault vehicle is uninsured, the at-fault driver is unidentified, or the insurer is insolvent. Claimants can pursue the fund directly through civil court proceedings.
- What is subrogation (rücu hakkı) in Turkish insurance law? TTK Article 1472 grants an insurer that has paid a claim the statutory right to pursue the third party responsible for the loss up to the amount paid. The right arises automatically upon payment without requiring a specific assignment from the insured.
- Can a foreign insurance company operate in Turkey? Yes — through a Turkish subsidiary licensed as an insurer or through a branch of the foreign company. Both approaches require SEDDK licensing and ongoing regulatory compliance.
- Do you represent both policyholders and insurers? Yes — we represent policyholders challenging claim denials or pursuing coverage disputes, and we represent insurers and reinsurers in subrogation recovery, regulatory compliance, licensing, and defense of coverage litigation.
