Introduction
Defective services in Turkey are one of the most frequent causes of consumer disputes. A consumer may pay for a private medical treatment, vehicle repair, renovation work, education service, tourism package, internet subscription, beauty procedure, transportation service, or technical maintenance service and later discover that the service was incomplete, delayed, poorly performed, misleadingly advertised, or materially different from what was promised. In such situations, Turkish Consumer Law gives consumers specific legal remedies against the service provider.
The main statute governing consumer protection in Turkey is Law No. 6502 on the Protection of Consumers. The law regulates consumer transactions, defective goods, defective services, unfair contract terms, distance contracts, consumer arbitration committees, and consumer courts. Defective services are specifically regulated under Articles 13 to 16 of Law No. 6502. Under Article 13, a defective service is a service that does not conform to the contract because it did not start within the contractual period or lacks the agreed or objectively required characteristics. Services containing material, legal, or economic deficiencies may also be considered defective if they reduce or remove the value or expected benefit of the service for the consumer.
For consumers, these rules are important because a defective service does not always mean that the service was never performed. A service may still be legally defective even if it was partially performed, if the result is poor, delayed, incomplete, unsafe, non-compliant with professional standards, or inconsistent with the advertisement, contract, website statement, or written promise of the service provider.
What Is a Defective Service Under Turkish Consumer Law?
Under Turkish Consumer Law, a defective service is not limited to a completely failed service. A service may be defective where it does not start on time, does not comply with the contract, does not have the qualities agreed by the parties, or lacks the characteristics that it should objectively contain. The Ministry of Trade’s consumer guidance similarly states that services that fail to carry the qualities announced by the provider, shown on an internet portal, or included in advertisements may qualify as defective services if they contain material, legal, or economic deficiencies reducing the expected benefit.
This definition is broad and consumer-friendly. For example, if a private course promises a certain number of lessons but fails to provide them, the service may be defective. If a vehicle repair service charges for a repair but fails to solve the problem, the service may be defective. If a travel agency sells a package holiday with specific hotel standards but provides a materially inferior service, the consumer may rely on defective service rules. If a renovation contractor performs poor-quality work that requires correction, the consumer may request legal remedies.
The key point is conformity. The service must conform to the contract, the consumer’s reasonable expectations, the provider’s representations, and the objective standards of the relevant sector. If the service falls below these standards, the consumer may have a claim.
Difference Between Defective Goods and Defective Services
Defective goods and defective services are related but different legal concepts. Defective goods concern products such as vehicles, electronics, furniture, white goods, clothing, or household items. Defective services concern performance-based obligations such as repair, education, healthcare, tourism, transportation, beauty treatment, legal or technical consultancy, subscription services, and maintenance.
The distinction matters because the available remedies and factual analysis may differ. In defective goods cases, the dispute usually focuses on the condition of a product at delivery. In defective service cases, the dispute focuses on the quality, timing, completeness, legality, and result of the service performed.
However, some consumer disputes involve both goods and services. For example, a consumer may buy an air conditioner and also pay for installation. If the device is technically sound but the installation is wrong, the issue may be framed as defective service. If both the product and installation are problematic, the consumer may need to rely on both defective goods and defective services provisions.
Service Provider’s Liability
Article 14 of Law No. 6502 provides that the supplier is obliged to perform the service in conformity with the contract. This means that the service provider cannot simply argue that it made an effort; it must deliver a service that corresponds to the contractual promise and legal standard.
In consumer disputes, service providers often rely on general defenses such as “the consumer misunderstood,” “the service was performed,” “the result was not guaranteed,” or “the problem was caused by the consumer.” These defenses may be valid in some cases, but they must be supported by evidence. If the provider advertised a specific result, gave written assurances, issued service forms, accepted payment for a particular repair, or undertook a defined obligation, those documents may be used to determine whether the service was defective.
A service provider may also argue that it is not bound by an advertisement or announcement if it proves that it was not and could not reasonably have been aware of the announcement, that the announcement was corrected at the time of the contract, or that the consumer’s decision to enter the contract was not causally linked to that announcement. This is a narrow evidentiary defense, not a general right to ignore advertising representations.
Consumer’s Elective Rights in Defective Service Cases
When a service is performed defectively, Turkish Consumer Law gives the consumer several elective rights. Under Article 15 of Law No. 6502, the consumer may request:
- Re-performance of the service
- Free repair of the work resulting from the service
- Price reduction in proportion to the defect
- Rescission of the contract
The supplier is obliged to fulfill the consumer’s preferred request, and the expenses arising from the exercise of the chosen right must be borne by the supplier. The consumer may also request compensation together with one of these rights under the Turkish Code of Obligations.
These remedies are powerful because they allow the consumer to select the remedy most appropriate to the situation. For example, if a repair service failed but can still be properly completed, re-performance may be suitable. If a renovation produced a defective result, free repair of the defective work may be appropriate. If the service was partially useful but below the promised standard, price reduction may be more reasonable. If the service fundamentally failed, rescission and refund may be justified.
Re-Performance of the Service
Re-performance means that the service provider must perform the service again in a proper manner. This remedy is especially suitable where the service can realistically be repeated without creating significant inconvenience for the consumer.
For example, if a cleaning company fails to provide the promised level of cleaning, the consumer may request that the service be performed again. If a vehicle repair service fails to repair the defect, the consumer may request proper re-performance. If an educational service fails to provide certain promised classes, additional sessions may be requested.
However, re-performance must be meaningful. A service provider should not use re-performance as a way to delay the consumer’s other rights. If the service is repeatedly defective, if the consumer has lost confidence, or if re-performance would not solve the problem, the consumer may have stronger grounds to request price reduction, refund, or compensation.
Article 15 also states that where re-performance is chosen, the service must be completed within a reasonable time and in a manner that does not cause significant problems for the consumer. In any case, this period cannot exceed thirty business days from the date the request is made to the supplier. If this period is exceeded, the consumer may exercise other elective rights.
Free Repair of the Resulting Work
In some defective service disputes, the service produces a tangible result. Renovation work, vehicle repair, furniture assembly, installation services, tailoring, technical maintenance, and beauty procedures may create a result that can be repaired or corrected.
In such cases, the consumer may request free repair of the work resulting from the service. This means that the provider must correct the defect without charging additional labor, material, transportation, or service fees. The consumer should not be asked to pay again for correcting a defect caused by poor or incomplete performance.
For example, if a renovation contractor installs tiles incorrectly, the consumer may request correction. If a vehicle service performs a defective repair that causes the same fault to continue, free correction may be required. If a technical service improperly installs a device, the consumer may request proper installation without extra cost.
The legal strength of a free repair request depends on evidence. Photographs, videos, expert reports, service forms, invoices, and written correspondence are essential. In technical disputes, an independent expert opinion may be necessary to prove that the result is defective.
Price Reduction
Price reduction is an important remedy where the consumer received some benefit from the service, but the service was not worth the full price due to defects. Instead of canceling the entire contract, the consumer keeps the benefit received and requests a reduction proportionate to the defect.
For instance, if a hotel package was partially performed but with lower quality than promised, a proportional refund may be appropriate. If a private course delivered some lessons but failed to provide the full promised program, the consumer may request a reduction. If a renovation service was completed but with quality deficiencies, price reduction may be a practical remedy.
The amount of price reduction should correspond to the difference between the value of the service as promised and the value of the service as actually performed. In many cases, expert examination may be required to calculate this difference.
Under the Ministry of Trade’s guidance, when a consumer chooses price reduction or rescission, the paid amount or the reduced portion must be returned immediately.
Rescission of the Contract and Refund
Rescission is the strongest remedy in defective service disputes. It means that the consumer withdraws from the contract because the service was defective and requests the return of the amount paid.
This remedy is most appropriate where the service has fundamentally failed, where the consumer received no meaningful benefit, where the provider’s breach is serious, or where repair or re-performance would not adequately protect the consumer.
For example, if a tourism company fails to provide the essential parts of a package tour, rescission may be considered. If a private course never begins despite payment, the consumer may request refund. If a technical service causes damage rather than repairing the item, rescission and compensation may be claimed. If an aesthetic or healthcare-related consumer service is materially different from what was promised, the refund request may be evaluated together with compensation depending on the damage suffered.
A refund claim should be clearly stated in writing. The consumer should identify the contract, payment date, service promised, defect, evidence, and legal basis. A vague complaint may be less effective than a structured written demand relying on defective service provisions.
Compensation Claims Together with Elective Rights
Defective service remedies do not necessarily exclude compensation. Article 15 of Law No. 6502 expressly allows the consumer to request compensation together with one of the elective rights in accordance with the Turkish Code of Obligations.
This is important because a defective service may cause additional losses beyond the service price. A defective vehicle repair may cause towing costs, additional repair costs, loss of use, or further mechanical damage. A defective renovation may cause property damage, replacement costs, accommodation expenses, or delay damages. A defective tourism service may cause additional accommodation, transportation, or cancellation expenses. A defective healthcare or beauty service may cause physical, emotional, or financial harm, although such claims require careful legal and evidentiary analysis.
To claim compensation, the consumer should prove the defective service, damage, causal link, and amount of loss. In practice, invoices, expert reports, photographs, medical records, correspondence, bank records, and witness statements may be important.
Proportionality and Disproportionate Difficulty
Although consumers have strong rights, the law also considers proportionality. If free repair or re-performance would create disproportionate difficulty for the service provider, the consumer may not be able to insist on those specific remedies. In determining disproportion, factors such as the non-defective value of the service, importance of the defect, and whether other remedies would create a problem for the consumer are considered.
This rule prevents unreasonable outcomes. For example, if re-performing a service would be excessively burdensome compared to the nature of the defect, price reduction may be more appropriate. However, proportionality should not be used as an excuse by service providers to avoid responsibility. The provider must still offer an effective remedy.
In practice, proportionality is often assessed by looking at the seriousness of the defect, the cost of correction, the consumer’s actual loss, whether the service can be repeated, and whether the consumer can still reasonably benefit from the service.
Limitation Period for Defective Service Claims
Limitation periods are critical in consumer disputes. Under Article 16 of Law No. 6502, unless a longer period is provided by law or contract, liability for defective service is subject to a two-year limitation period from the time the service was performed, even if the defect becomes apparent later. If the defect was hidden through gross negligence or deceit, limitation provisions do not apply.
Consumers should not delay. Even where the consumer is legally right, late action may weaken both the legal claim and the available evidence. Written notices, service records, photographs, expert reports, and correspondence should be preserved as early as possible.
Service providers should also keep records for the relevant period. Contracts, service forms, customer approvals, delivery records, technical reports, employee notes, payment receipts, and complaint responses may become decisive evidence if a dispute arises.
Evidence in Defective Service Disputes
Evidence is often the most important factor in defective service cases. Unlike defective goods, where the product itself may be inspected, defective services may be harder to prove because performance occurs over time and may not leave clear physical evidence.
Consumers should preserve:
- Service contract or written offer
- Invoice, receipt, or bank payment record
- Advertisement, brochure, website screenshot, or social media announcement
- WhatsApp messages, emails, SMS records, and call center records
- Service forms, repair records, delivery documents, and appointment records
- Photographs and videos showing the defective result
- Expert reports or technical opinions
- Medical records, if the dispute involves healthcare or aesthetic services
- Witness information, where relevant
For online or digitally advertised services, screenshots are particularly important. The service provider may later change the website, remove campaign statements, or modify service descriptions. Early documentation protects the consumer.
Common Examples of Defective Services in Turkey
Defective service disputes arise in many sectors. Some of the most common examples include:
Vehicle repair services: The mechanic fails to fix the defect, uses improper parts, causes additional damage, or charges for unnecessary work.
Renovation and construction services: The contractor performs poor-quality work, delays completion, uses lower-quality materials, or leaves the work incomplete.
Private education services: The course fails to provide promised lessons, instructors, materials, certificates, or program duration.
Tourism and package travel services: The hotel, transportation, tour content, or promised facilities differ materially from the advertised package.
Internet and telecom services: The provider fails to deliver the promised speed, continuity, installation, or cancellation process.
Beauty and aesthetic services: The service is performed contrary to professional standards, promised procedures are not carried out, or the result causes harm.
Technical services: The provider fails to repair electronics, appliances, air conditioners, or other devices despite charging a fee.
Each sector requires a different evidentiary approach. A vehicle repair dispute may require mechanical expert examination. A renovation dispute may require construction expertise. A tourism dispute may rely heavily on advertisements, booking documents, photographs, and witness statements.
Consumer Arbitration Committees in Defective Service Cases
For lower-value consumer disputes, Consumer Arbitration Committees are the primary dispute resolution mechanism. These committees are designed to resolve consumer disputes in a faster and more accessible way than court litigation. The Ministry of Trade explains that Consumer Arbitration Committees are established to resolve disputes arising from consumer transactions and consumer-oriented practices under Law No. 6502.
For 2026, consumer disputes with a value below TRY 186,000 fall within the jurisdiction of Provincial or District Consumer Arbitration Committees. Disputes of TRY 186,000 or more cannot be decided by these committees; such disputes must proceed through mandatory mediation under Article 73/A and then Consumer Courts, or civil courts acting as Consumer Courts where no separate Consumer Court exists.
Applications may be filed personally or through an attorney, by hand, by post, or electronically through e-Government via TÜBİS. Oral applications are not accepted, and applications must include the dispute, request, value in Turkish lira, and supporting documents.
A strong defective service application should clearly explain the service promised, service performed, defect, evidence, legal remedy requested, and amount in dispute.
Consumer Courts and Mandatory Mediation
Where the dispute exceeds the Consumer Arbitration Committee threshold or falls outside the committee’s jurisdiction, the consumer may need to proceed through mandatory mediation and then file a case before the Consumer Court. This is especially common in high-value renovation disputes, serious vehicle repair disputes, private healthcare disputes, expensive education agreements, and major tourism or subscription disputes.
Consumer Court proceedings may involve expert examination. The expert may evaluate whether the service was defective, whether the defect is attributable to the provider, whether the consumer contributed to the problem, whether re-performance is possible, and what amount should be refunded or compensated.
For this reason, the petition should be precise. It should identify the consumer transaction, the contractual promise, the defective performance, the evidence, the legal remedy, and the amount claimed. A technically weak petition may lead to an unfavorable expert report or incomplete judicial review.
Practical Steps for Consumers
A consumer facing a defective service should act systematically. First, the consumer should document the defect immediately. Second, the consumer should notify the service provider in writing. Third, the consumer should choose the preferred remedy clearly. Fourth, the consumer should preserve all evidence. Fifth, the consumer should apply to the correct legal authority depending on the dispute value.
The written notice should not merely say “I am dissatisfied.” It should state that the service is defective, explain why, refer to the legal remedy requested, and demand performance within a reasonable time where appropriate.
For example, a consumer may write: “The service was performed defectively because the promised repair was not completed and the same malfunction continues. Under Law No. 6502, I request re-performance/free correction/refund/price reduction.”
Practical Steps for Service Providers
Businesses should treat defective service complaints seriously. A poor complaint-handling process may turn a solvable issue into a legal dispute. Providers should maintain written contracts, clear service descriptions, detailed invoices, customer approvals, service forms, and complaint response records.
Providers should avoid vague promises in advertisements. If a business promises a specific result, duration, standard, or benefit, it may later be held responsible for that representation. Advertising language, website content, brochures, and sales messages should be consistent with the actual service.
Where a complaint arises, the provider should respond in writing, investigate the issue, offer a legally appropriate solution, and preserve all technical records. Unsupported statements such as “there is no defect” or “the consumer caused the problem” may not be persuasive without evidence.
Why Legal Assistance Matters
Defective service disputes may appear simple, but they can become complex when technical standards, expert reports, limitation periods, contractual interpretation, compensation claims, and procedural rules are involved. Legal assistance can help determine the correct forum, prepare evidence, select the proper remedy, and draft a persuasive application or lawsuit.
For consumers, a lawyer can help frame the issue as a defective service claim rather than a general complaint. For service providers, legal assistance can reduce litigation risk, improve contract drafting, structure complaint procedures, and defend against unfounded claims.
High-value disputes, especially those involving healthcare, construction, vehicle repair, tourism, education, or long-term subscriptions, should be evaluated carefully before any legal step is taken.
Conclusion
Defective services in Turkey are regulated under Law No. 6502 on the Protection of Consumers. A service may be defective if it does not start on time, does not conform to the contract, lacks agreed or objective characteristics, contains material, legal, or economic deficiencies, or fails to provide the value and benefit reasonably expected by the consumer.
Consumers have several legal remedies: re-performance of the service, free repair of the resulting work, price reduction, rescission of the contract, and compensation where the legal conditions are met. The service provider must generally fulfill the consumer’s chosen remedy, and the expenses arising from the exercise of these rights must be borne by the provider.
For consumers, success depends on timely action, strong evidence, clear written notice, correct remedy selection, and filing before the proper authority. For businesses, compliance depends on transparent service descriptions, fair contracts, accurate advertising, proper performance records, and effective complaint management.
In Turkish Consumer Law, defective service claims are not merely about dissatisfaction. They are legal claims based on non-conformity, contractual failure, objective service standards, and consumer protection principles. A well-prepared claim or defense can make the difference between a rejected complaint and an effective legal remedy.
