Introduction
Compensation for breach of commercial contracts in Turkey is one of the most important areas of Turkish commercial litigation. Commercial life is built on trust, performance, payment discipline, delivery schedules, quality standards, confidentiality, exclusivity, distribution networks, supply chains, investment obligations, and long-term business cooperation. When one party fails to perform its contractual obligations, performs late, performs defectively, refuses payment, delivers non-conforming goods, violates exclusivity, terminates the contract unlawfully, or causes commercial loss, the injured party may have the right to claim compensation.
Commercial contract disputes in Turkey may arise from sales contracts, supply agreements, distribution agreements, agency contracts, franchise agreements, service contracts, construction contracts, software and IT contracts, logistics agreements, manufacturing contracts, lease-related commercial arrangements, consultancy agreements, shareholder-related commercial obligations, international trade contracts, and joint venture agreements.
The main legal framework is the Turkish Code of Obligations No. 6098 and the Turkish Commercial Code No. 6102. The Turkish Code of Obligations contains the general rules on contract formation, non-performance, defective performance, debtor default, damages, limitation of liability, penalty clauses, and limitation periods. The Turkish Commercial Code regulates commercial enterprises, merchants, commercial transactions, commercial lawsuits, company-related disputes, negotiable instruments, unfair competition, and many other commercial matters.
For foreign companies, investors, exporters, importers, suppliers, manufacturers, distributors, software companies, logistics providers, and international business partners dealing with Turkish counterparties, understanding Turkish contract compensation law is essential. A breach of contract case in Turkey is not only about proving that the other party acted unfairly. The claimant must prove the contract, the obligation breached, the damage suffered, the causal link between breach and damage, and the legally recoverable amount.
What Is a Breach of Commercial Contract?
A breach of commercial contract occurs when a party fails to perform an obligation arising from a valid commercial agreement. The breach may consist of total non-performance, late performance, partial performance, defective performance, refusal to pay, violation of confidentiality, breach of exclusivity, failure to deliver goods, delivery of defective goods, failure to complete a project, wrongful termination, failure to provide services, or failure to comply with agreed quality, quantity, timing, or technical standards.
In Turkish law, contractual liability is primarily governed by the Turkish Code of Obligations. Article 112 provides the general rule: if a debt is not performed at all or is not duly performed, the debtor must compensate the creditor’s resulting damage unless the debtor proves that no fault can be attributed to them. This rule is one of the core provisions for contractual compensation claims in Turkey.
This means that once the creditor establishes non-performance or improper performance, the debtor may need to prove absence of fault to avoid liability. In practice, this is particularly important in commercial disputes because the defaulting party may argue force majeure, impossibility, supply chain disruption, creditor fault, defective instructions, market conditions, or contractual excuse.
Common Types of Breach in Commercial Contracts
Commercial contracts can be breached in many ways. The most common form is non-payment. A buyer may receive goods or services but fail to pay invoices. Another common form is non-delivery. A supplier may fail to deliver goods on the agreed date, in the agreed quantity, or according to agreed technical standards.
Defective performance is also frequent. Goods may be delivered but may not meet specifications, quality requirements, certificates, samples, packaging standards, technical drawings, or contractual warranties. Services may be provided but may be incomplete, late, careless, or commercially useless. Software may be delivered but may not function as agreed. A construction contractor may complete work with defects, delays, or missing items.
Wrongful termination is another major breach. A party may terminate a long-term commercial agreement without legal basis, without respecting notice periods, without following contractual cure procedures, or in violation of exclusivity or minimum purchase commitments. Such termination may cause loss of profit, wasted investment, stock losses, employee costs, marketing losses, reputational damage, and loss of future business.
Confidentiality breaches, non-compete violations, customer poaching, unauthorized use of know-how, and violation of exclusivity clauses may also lead to compensation claims, especially in distribution, franchise, technology, consultancy, and joint venture agreements.
Legal Basis of Contractual Damages in Turkey
Article 112 of the Turkish Code of Obligations is the main provision for compensation arising from non-performance or improper performance. It establishes that the debtor is liable for damage caused by non-performance unless the debtor proves lack of fault. Article 113 further provides remedies for obligations to do or not to do something. If an obligation to act is not performed, the creditor may request authorization for performance by the creditor or a third person at the debtor’s expense, while preserving compensation rights; if an obligation not to act is breached, the debtor must compensate the resulting damage and may also be required to remove the unlawful condition.
Article 114 states that the debtor is generally liable for every kind of fault, and that tort liability provisions apply by analogy to contractual breach where appropriate. This is important because principles such as causation, mitigation, contributory fault, and scope of damages may also influence contractual compensation analysis.
Commercial compensation claims must therefore be structured around several questions: What was the contractual obligation? Was it breached? Was the breach attributable to the debtor? What damage did the creditor suffer? Was the damage caused by the breach? Is the claimed amount foreseeable, provable, and legally recoverable? Are there contractual clauses limiting liability, regulating penalties, or setting special procedures?
Material Damages in Commercial Contract Disputes
Material damages are financial losses suffered by the injured commercial party. In breach of commercial contract cases, material damages may include unpaid invoices, replacement costs, repair costs, wasted expenses, additional procurement costs, storage expenses, transportation costs, customs expenses, inspection costs, third-party penalties, production interruption losses, loss of profit, loss of customers, loss of business opportunity, and costs incurred because of the other party’s breach.
For example, if a supplier fails to deliver raw materials on time, the buyer may suffer production stoppage, delay penalties owed to its own customers, higher replacement purchase costs, overtime costs, and loss of profit. If a contractor delivers defective machinery, the buyer may claim repair costs, replacement costs, installation costs, production losses, and expert inspection expenses. If a distributor unlawfully terminates an agreement, the other party may claim lost margin, wasted marketing investment, unsold inventory losses, and damage caused by sudden market disruption.
The key point is proof. Turkish courts generally require documentary and expert evidence for commercial damages. Contracts, invoices, delivery notes, customs declarations, e-mails, purchase orders, accounting books, bank records, expert reports, technical inspection reports, warehouse records, customer cancellation documents, production records, and commercial correspondence may all be decisive.
Actual Loss and Loss of Profit
Commercial damages are commonly divided into actual loss and loss of profit. Actual loss refers to the reduction in existing assets. It may include money paid, expenses incurred, goods damaged, repair costs, replacement costs, or amounts paid to third parties because of the breach.
Loss of profit refers to the profit the injured party would probably have earned if the contract had been properly performed. This is often the most valuable part of a commercial compensation claim, but also the hardest to prove. Turkish courts will generally not award speculative or hypothetical profits. The claimant should support the claim with past sales data, profit margins, confirmed orders, customer contracts, market data, accounting records, capacity reports, and expert calculations.
For example, a company claiming that it lost customers due to delayed delivery must show more than general dissatisfaction. It should show specific orders, expected margin, cancellation documents, market price, replacement attempts, and the connection between delay and loss. A distributor claiming loss of future profit after unlawful termination should show sales history, territory performance, contract duration, expected volume, margin, and investments made in reliance on the contract.
Delay in Performance and Debtor Default
Delay is one of the most common breaches in commercial contracts. Under Article 117 of the Turkish Code of Obligations, a debtor of a due obligation generally falls into default upon notice by the creditor. If the date of performance has been jointly determined or can be determined based on a right reserved in the contract, default may occur when that date passes without performance.
Article 118 provides that a debtor in default is liable for damage caused by late performance unless the debtor proves that they were not at fault. This allows the creditor to claim delay damages such as production loss, storage expenses, substitute purchase costs, contractual penalties owed to third parties, additional logistics costs, or financial losses caused by late performance.
In commercial practice, a written notice is often critical. A claimant should send a formal notice when payment is overdue, delivery is late, or performance is defective. The notice should identify the contract, breached obligation, deadline, requested performance, damages, and legal consequences. In some cases, the contract may require a cure period before termination or compensation. Failure to comply with contractual notice procedures may weaken the claim.
Default Interest and Excess Damage
In payment disputes, default interest may be significant. Article 120 of the Turkish Code of Obligations provides rules on default interest where the rate is not contractually agreed, and Article 122 allows the creditor to claim damage exceeding default interest if the creditor suffered a greater loss and the debtor cannot prove absence of fault.
Commercial parties often agree on interest clauses, payment deadlines, foreign currency obligations, exchange rate rules, penalty interest, and default consequences. These clauses should be reviewed carefully. If the parties are merchants and the debt is commercial, commercial interest rules may also become relevant depending on the transaction and applicable legislation.
A well-prepared commercial lawsuit should not simply request “interest.” It should identify the correct starting date, interest type, contractual basis, statutory basis, currency, and whether excess damage is claimed. In foreign currency disputes, exchange rate loss and default interest must be analyzed carefully.
Penalty Clauses in Commercial Contracts
Penalty clauses are widely used in Turkish commercial contracts. They may apply to delay, non-performance, defective performance, breach of confidentiality, violation of exclusivity, early termination, failure to meet minimum purchase commitments, non-compete violations, or breach of delivery schedules.
Article 179 of the Turkish Code of Obligations provides that if a penalty is agreed for non-performance or improper performance, the creditor may generally request either performance of the obligation or payment of the penalty, unless otherwise understood from the contract. If the penalty is agreed for failure to perform at the specified time or place, the creditor may request both performance and penalty unless the creditor expressly waived the right or accepted performance without reservation.
Article 180 provides that the agreed penalty is due even if the creditor suffered no damage. However, if the creditor’s actual damage exceeds the penalty, the excess amount generally cannot be claimed unless the creditor proves the debtor’s fault. Article 182 allows parties to freely determine the amount of penalty, but the judge may reduce an excessive penalty ex officio.
This is critical in commercial litigation. A penalty clause may be powerful, but it must be drafted and invoked correctly. If the creditor accepts delayed performance without reservation, the right to claim delay penalty may be disputed. If the penalty is excessive, judicial reduction may be possible. If the creditor wants both penalty and additional damages, the contract and Article 180 must be analyzed carefully.
Limitation of Liability Clauses
Commercial contracts often include limitation of liability clauses, exclusion clauses, warranty limitations, force majeure clauses, caps on damages, indirect loss exclusions, and clauses excluding loss of profit. Turkish law generally respects freedom of contract, but there are limits.
Article 115 of the Turkish Code of Obligations provides that an advance agreement excluding liability for gross fault is null and void. It also contains specific restrictions for certain service and professional relationships.
Therefore, a party cannot always rely on a liability exclusion clause. If the breach involves gross negligence, intentional conduct, bad faith, or breach of mandatory rules, the limitation may be challenged. In addition, general terms and conditions may be subject to special review if they were not individually negotiated, were not properly brought to the other party’s attention, are unclear, or unfairly aggravate the counterparty’s position.
In international commercial contracts, limitation clauses should be reviewed under Turkish mandatory rules, the chosen law clause, jurisdiction clause, and dispute resolution mechanism.
Force Majeure and Impossibility
A defaulting commercial party may argue force majeure or impossibility. Force majeure may include extraordinary, unforeseeable, unavoidable events beyond the control of the parties that prevent performance. Examples may include natural disasters, war, embargo, severe governmental restrictions, export bans, port closures, or other exceptional events depending on the contract.
However, commercial difficulty, market price increases, ordinary supply problems, currency fluctuations, or increased cost do not automatically release a party from liability. The court will examine the contract, nature of the obligation, foreseeability, causation, whether performance became impossible or merely more expensive, and whether the party took reasonable mitigation measures.
A force majeure defense should be supported with evidence. The debtor should show the event, its effect on performance, timely notice, impossibility or serious impediment, lack of fault, and reasonable steps taken to reduce damage. The creditor should examine whether the defense is genuine or merely an excuse for commercial non-performance.
Unlawful Termination of Commercial Contracts
Unlawful termination is a frequent source of compensation. Commercial contracts often include termination clauses, notice periods, cure periods, minimum term obligations, exclusive territory protections, investment obligations, and post-termination duties.
If a party terminates without contractual or legal basis, the other party may claim compensation. The claim may include loss of profit for the remaining contract period, wasted investment, employee costs, marketing expenses, unsold stock, loss of customer network, third-party penalties, and other damages caused by sudden termination.
However, termination claims require careful analysis. The claimant should prove that the contract was still in force, termination was unlawful, contractual procedures were not followed, no valid breach justified termination, and the claimed losses resulted from the termination. If the contract was indefinite-term, reasonable termination notice, good faith, commercial custom, and the nature of the relationship may be relevant.
Breach of Distribution, Agency and Franchise Agreements
Distribution, agency and franchise disputes often involve complex commercial damages. A Turkish distributor may claim that a foreign supplier unlawfully terminated the agreement after the distributor invested in the market. A foreign company may claim that a Turkish distributor failed to meet sales targets, sold competing products, violated exclusivity, failed to pay invoices, or damaged brand reputation.
Agency contracts may involve commission claims, portfolio compensation, unpaid receivables, territorial rights, and termination disputes. Franchise disputes may involve brand use, quality standards, royalty payments, training obligations, know-how, non-compete clauses, and investment losses.
These cases require strong evidence. Sales reports, order history, invoices, commission statements, territory data, marketing expenses, customer lists, termination notices, correspondence, performance reports, and expert financial calculations may be essential.
Breach of Construction and Project Contracts
Commercial construction contracts, fit-out agreements, engineering contracts, installation contracts, and project delivery agreements frequently lead to compensation claims. Breaches may include delay, defective work, failure to meet technical specifications, incomplete work, unauthorized materials, failure to obtain approvals, non-payment of progress payments, or unlawful termination.
In such disputes, expert reports are usually decisive. Technical experts may examine whether the work conforms to the contract, project, specifications, standards, and accepted practice. Financial experts may calculate delay damages, repair costs, completion costs, penalty clauses, and loss of profit.
The claimant should preserve project documents, technical drawings, site records, delivery minutes, progress payment documents, inspection reports, photographs, correspondence, change orders, and expert determinations.
Breach of Software and Technology Contracts
Software, IT, SaaS, licensing, system integration, cybersecurity, e-commerce, and digital service contracts are increasingly common sources of commercial disputes in Turkey. Breaches may involve non-delivery of software, failure to meet functional requirements, data migration problems, security failures, defective coding, service interruption, breach of service level agreements, unauthorized use of software, or non-payment of license fees.
Such disputes require technical and legal precision. The contract should define deliverables, acceptance criteria, testing procedures, support obligations, service levels, intellectual property rights, confidentiality, data protection, limitation of liability, and termination rights.
Evidence may include source code records, ticket systems, project management logs, e-mails, test reports, user acceptance documents, server logs, invoices, technical expert reports, and customer complaints.
Mandatory Mediation in Commercial Compensation Claims
Commercial compensation claims in Turkey often require mandatory mediation before filing a lawsuit. The Turkish Commercial Code Article 5/A rule is summarized by mediation sources as follows: for commercial lawsuits specified in Article 4 of the Turkish Commercial Code and other laws, where the subject matter concerns money, compensation, cancellation of objection, negative declaratory, or restitution claims, applying to mediation is a prerequisite before filing the lawsuit.
Legal commentary also explains that Article 5/A applies to commercial actions where the dispute concerns a pecuniary claim arising from debt or damages, and that both absolute and relative commercial actions may fall within the mandatory mediation framework if the statutory conditions are met.
This procedural requirement is crucial. If a claim is subject to mandatory mediation and the claimant files directly before the commercial court without completing mediation, the lawsuit may be dismissed for lack of a procedural condition. Therefore, before filing a commercial compensation lawsuit, the lawyer must determine whether the dispute is a commercial action and whether the claim concerns money or compensation.
Mediation should not be treated as a formality. It is an opportunity to clarify claims, present documentary evidence, evaluate risk, negotiate payment, agree on installments, obtain acknowledgment of debt, or preserve commercial relationships. However, any settlement should be drafted carefully to avoid ambiguity, tax issues, enforcement problems, or waiver of future rights.
Evidence in Commercial Contract Compensation Cases
Evidence is the foundation of every breach of commercial contract claim. The claimant should collect the signed contract, amendments, purchase orders, invoices, delivery notes, acceptance minutes, e-mails, WhatsApp messages, payment records, bank statements, customs documents, technical specifications, quality certificates, expert reports, accounting records, commercial books, stock records, production records, customer cancellation documents, and notices.
In commercial litigation, the chronology is very important. The court should be able to see when the contract was signed, what each party promised, when performance was due, what was delivered, what was rejected, when notices were sent, how damage occurred, and how the amount was calculated.
If the dispute involves defective goods or services, technical expert evidence may be necessary. If the dispute involves loss of profit, accounting and financial expert reports may be required. If the dispute involves software, construction, machinery, textiles, logistics, food, medical devices, or manufacturing, sector-specific experts may be needed.
Burden of Proof and Expert Reports
The claimant generally must prove the contract, breach, damage, and causation. The debtor may defend by arguing absence of fault, force majeure, creditor default, proper performance, contractual limitation, lack of damage, mitigation failure, or invalidity of penalty clause.
Expert reports are often decisive in Turkish commercial litigation. Experts may calculate unpaid receivables, loss of profit, foreign exchange loss, commercial interest, penalty clauses, defective performance costs, replacement costs, and technical conformity.
A party should not accept an expert report blindly. Reports may contain calculation errors, ignore contractual clauses, use wrong exchange rates, omit invoices, misread commercial books, rely on incomplete documents, or fail to distinguish actual loss from loss of profit. Detailed objections should identify each error clearly and request additional or new expert examination if necessary.
Limitation Periods for Commercial Contract Compensation
Limitation periods must be checked before filing a commercial compensation claim. Article 146 of the Turkish Code of Obligations provides the general rule that every receivable is subject to a ten-year limitation period unless the law provides otherwise. Article 147 provides a five-year period for certain claims, including periodic payments, certain small-scale sales and work claims, partnership-related claims, agency, commission and brokerage-related claims, and certain work contract claims unless the contractor acted with gross fault. Article 149 provides that limitation generally begins when the receivable becomes due.
This means that commercial contract claims should not be assumed to have a single universal limitation period. The applicable period may vary depending on the contract type, receivable type, maturity date, agency relationship, construction/work contract nature, periodic payment structure, or special law.
In practice, limitation analysis should be made before mediation and lawsuit. If the limitation period is close to expiry, the claimant should take appropriate legal steps without relying only on informal negotiations.
Interest, Currency and Exchange Rate Issues
Commercial contracts often involve foreign currency, international transfers, exchange rate differences, late payment interest, and inflation-related losses. Turkish law allows parties to agree on certain payment and interest terms within legal limits, but the enforceability and calculation method should be reviewed carefully.
In a commercial lawsuit, the claimant should clearly state the claimed currency, whether payment is requested in foreign currency or Turkish lira equivalent, interest type, interest starting date, contractual clause, default notice, and exchange rate date if relevant.
If the creditor suffered loss beyond default interest, Article 122 may allow a claim for excess damage under the relevant conditions. However, such claims require proof. The claimant should not simply allege exchange rate loss or financing cost; it should provide bank records, credit costs, payment history, foreign currency obligations, and expert calculation.
Interim Measures and Preservation of Rights
In some commercial disputes, ordinary litigation may not be enough. The claimant may need interim measures, attachment, evidence preservation, injunctions, or urgent protection to prevent further damage.
For example, if the debtor is hiding assets, precautionary attachment may be considered. If defective goods may disappear, evidence preservation may be needed. If confidential information is being misused, an injunction may be necessary. If a distributor is unlawfully using a trademark or customer database, urgent legal protection may be required.
The availability of interim remedies depends on the facts, evidence, urgency, probability of claim, security deposit requirements, and court discretion. A strong preliminary file is essential.
Enforcement of Commercial Compensation Judgments
Winning a commercial compensation lawsuit is not always the end of the process. If the debtor does not pay voluntarily, enforcement proceedings may be necessary. In Turkey, court judgments and certain settlement documents may be enforced through execution offices.
Before filing a lawsuit, the claimant should consider collection strategy. Does the debtor have assets in Turkey? Are there bank accounts, receivables, real estate, vehicles, inventory, shares, or ongoing commercial operations? Is the debtor solvent? Is there a guarantor, surety, pledge, mortgage, letter of guarantee, or parent company obligation?
A commercially successful case is not only legally strong but also collectible. For foreign companies, enforcement planning is particularly important if the Turkish counterparty has limited assets or may transfer assets during the dispute.
Commercial Contract Claims by Foreign Companies in Turkey
Foreign companies may file compensation claims in Turkey if Turkish courts have jurisdiction or if the contract provides Turkish jurisdiction or arbitration connected with Turkey. Many disputes involve foreign suppliers, Turkish distributors, international sales, logistics, manufacturing, agency, franchising, software, consulting, construction, and investment-related agreements.
Foreign companies should preserve corporate documents, board authorizations, powers of attorney, contracts, invoices, delivery records, customs documents, bank transfers, correspondence, technical reports, and accounting documents. Documents issued abroad may require sworn translation and apostille or consular legalization depending on the procedure.
Jurisdiction and governing law clauses must be reviewed carefully. If the contract contains arbitration, the dispute may need to be filed before an arbitral tribunal rather than Turkish courts. If the contract contains foreign law, Turkish mandatory rules and procedural law may still matter depending on where the case is heard.
Common Mistakes in Commercial Contract Compensation Claims
One common mistake is filing a lawsuit without completing mandatory mediation where required. This may cause procedural dismissal and loss of time.
Another mistake is claiming loss of profit without evidence. Courts require concrete data, not speculation.
A third mistake is failing to send timely default notice. In some cases, default, interest, penalty, termination, and delay damages depend on proper notice.
A fourth mistake is accepting defective or late performance without reservation. If a party accepts performance without objection, certain penalty or defect claims may become harder to assert.
A fifth mistake is ignoring limitation periods. Commercial negotiations do not always stop limitation from running.
A sixth mistake is relying only on invoices. A strong commercial damages file should include the contract, performance records, correspondence, delivery evidence, accounting data, and expert calculation.
Why Work With a Turkish Commercial Litigation Lawyer?
Compensation for breach of commercial contracts in Turkey requires legal, financial, procedural, and strategic analysis. A Turkish commercial litigation lawyer can review the contract, identify breached obligations, assess evidence, send default notices, calculate damages, initiate mandatory mediation, file lawsuits, request interim measures, manage expert reports, challenge defective calculations, negotiate settlement, and enforce judgments.
For foreign companies, legal representation is especially important because of language barriers, Turkish procedural rules, mediation requirements, notarization, apostille, sworn translation, jurisdiction issues, and enforcement strategy.
A commercial contract dispute should be handled not only as a legal claim but as a business recovery strategy. The goal is not merely to prove breach, but to recover money, protect commercial interests, preserve evidence, reduce risk, and reach an enforceable result.
Conclusion
Compensation for breach of commercial contracts in Turkey provides essential protection for companies and merchants harmed by non-payment, non-delivery, defective performance, delay, wrongful termination, confidentiality breaches, exclusivity violations, and other contractual failures. Turkish law allows injured commercial parties to claim actual loss, loss of profit, penalty clauses, default interest, excess damage, replacement costs, repair costs, and other financial losses where legally proven.
The Turkish Code of Obligations provides the core contractual liability framework. Article 112 establishes liability for non-performance or improper performance unless the debtor proves absence of fault. Articles 117 and 118 regulate debtor default and delay damages. Articles 179 to 182 regulate penalty clauses. Articles 146 to 149 regulate limitation periods and the starting point of limitation.
In commercial lawsuits involving monetary or compensation claims, mandatory mediation under Turkish Commercial Code Article 5/A may be a prerequisite before filing the case. Therefore, commercial compensation claims must be prepared with both substantive and procedural precision.
Anyone seeking compensation for breach of a commercial contract in Turkey should act quickly, preserve evidence, send proper notices, calculate losses carefully, complete mandatory mediation where required, and obtain legal advice before filing a lawsuit or signing a settlement. A well-prepared commercial compensation claim can make a decisive difference in recovering losses, enforcing contractual rights, and protecting long-term business interests.
