Learn how pre-contractual liability works in Turkey, including negotiations, bad faith, culpa in contrahendo, disclosure duties, confidentiality, reliance loss, and the legal consequences of misleading conduct before a contract is signed.
Introduction
Pre-contractual liability in Turkey concerns legal responsibility arising during the negotiation phase, before a final contract is concluded. Turkish law does not regulate this topic in one standalone article titled “pre-contractual liability.” Instead, the doctrine is built mainly on the good faith principle in Article 2 of the Turkish Civil Code, together with the broader structure of the Turkish Code of Obligations. Turkish legal writing commonly refers to this area as culpa in contrahendo, meaning fault in contracting or fault during negotiations. Turkish academic and professional sources also note that the doctrine developed through scholarship and case-law-oriented practice rather than through a single express code provision.
This matters because serious economic harm can occur before a contract is signed. One party may spend money on advisors, due diligence, travel, technical preparation, or internal restructuring because the other side’s conduct created justified confidence that negotiations were serious and honest. If the other side acted in bad faith, gave misleading information, abused confidential data, or continued negotiations without a genuine intention to conclude a contract, Turkish law may recognize liability even if no final agreement was ever formed. Turkish sources discussing culpa in contrahendo expressly describe the negotiation phase as capable of generating legal effects and protective duties grounded in trust and good faith.
For that reason, the key issue under Turkish law is not simply whether a contract was ultimately signed. The key issue is whether the parties’ conduct during negotiations respected the duties of honesty, care, trust, and fair dealing that arise once a real pre-contractual relationship has begun. This article explains pre-contractual liability in Turkey in practical English, focusing on negotiations, bad faith, misleading information, confidentiality, reliance loss, and the main doctrinal and statutory foundations of culpa in contrahendo under Turkish law.
The Statutory Foundation of Pre-Contractual Liability in Turkey
The main legal anchor is Article 2 of the Turkish Civil Code, which states that everyone must comply with the rules of honesty while exercising rights and performing obligations, and that the legal order does not protect the manifest abuse of a right. Turkish scholarship discussing pre-contractual liability repeatedly treats this provision as the central normative basis for duties arising during negotiations. In other words, even before a final contract exists, the law may require parties to behave honestly because negotiation itself can create a legally relevant relationship of trust.
The Turkish Code of Obligations complements that foundation. Article 1 states that a contract is formed through the parties’ mutual and corresponding declarations of intent, while Article 2 provides that if the parties agree on the essential points, the contract is deemed concluded even if secondary matters remain unresolved. These rules matter for pre-contractual liability because they show where the negotiation phase sits in the overall structure: before Articles 1 and 2 produce a final contract, the parties are still capable of causing legally significant harm through dishonest or careless negotiation conduct.
The general damages framework in the Turkish Code of Obligations also remains relevant. Article 49 requires compensation for damage caused by a faulty and unlawful act; Article 50 places the burden of proving damage and fault on the claimant; Article 51 gives the judge discretion to determine the form and scope of compensation according to the circumstances and degree of fault; and Article 52 allows reduction where the injured party consented, contributed to the damage, or worsened the defendant’s position. These provisions matter because Turkish doctrine still debates whether culpa in contrahendo is contractual, tortious, or sui generis, but in practical litigation the general law of fault, damage, causation, and reduction still plays a major role.
Is Pre-Contractual Liability Expressly Codified?
The short answer is no. Turkish legal commentary and academic writing expressly note that culpa in contrahendo is not laid down in one express, standalone article of the Turkish Code of Obligations. Instead, it has been developed through doctrine, comparative influence, and court-oriented reasoning. A Turkish legal article comparing pre-contractual duties states that Turkish law does not implicitly regulate the concept in one direct provision, but doctrine—following Swiss tradition—accepts a general principle of negotiating in good faith. A 2025 academic study on Turkish pre-contractual liability in financial leasing likewise treats the doctrine as a significant legal mechanism arising from negotiations, confidentiality, trust, and bad-faith conduct during the negotiation phase.
That does not make the doctrine weak. On the contrary, its importance lies in the fact that Turkish law does not treat the negotiation table as a law-free zone. Even if no final contract was signed, or even if the final contract later proves invalid, the law may still respond where one side abused the negotiation relationship and caused loss to the other side. This is precisely the gap that culpa in contrahendo fills in Turkish law.
The Nature of Pre-Contractual Liability Is Debated
One of the most interesting points in Turkish law is that the legal character of pre-contractual liability remains debated. Turkish scholarship described in academic and professional sources identifies three major approaches. One approach treats it as a form of contractual liability, arguing that the contract relationship should be understood as extending backward into the negotiation stage. Another treats it as tort liability, because there is not yet a final contract. A third approach treats it as sui generis liability, grounded in the trust relationship created during negotiations and in the combined force of good faith and diligence. The same Turkish source notes that Swiss jurisprudence has supported the sui generis understanding.
For practice, this debate matters for issues such as legal basis, damages theory, and limitation analysis. But it does not undermine the doctrine itself. Even where scholars disagree on classification, they still converge on the idea that parties who enter serious negotiations do not remain completely free to mislead, exploit, or injure the other side without consequences.
When Does a Pre-Contractual Relationship Begin?
Turkish sources on culpa in contrahendo make clear that liability presupposes a pre-contractual relationship between the parties. That relationship is more than a casual commercial contact. It emerges when negotiations become serious enough to create trust, reliance, information exchange, cost exposure, or transaction-specific expectations. Turkish academic commentary describes the negotiation phase as one in which a relationship based on mutual trust can arise, revealing protected interests between the parties.
In business practice, this may happen when parties exchange draft contracts, open a data room, discuss exclusivity, conduct site visits, request technical disclosures, exchange due diligence materials, or engage in structured negotiations over essential commercial terms. At that point, Turkish doctrine is more willing to recognize that each side owes duties not merely to itself, but also to the other side’s justified reliance.
The Core Duty: Negotiate in Good Faith
At the center of Turkish pre-contractual liability lies the duty to negotiate in good faith. Turkish academic commentary expressly states that the parties entering negotiations create a trust relationship and are expected to negotiate honestly and with due care. A comparative Turkish legal study likewise says that Turkish doctrine, as part of the Swiss/German tradition, accepts a general principle of negotiating in good faith even though the Code does not contain one express article under that title.
This does not mean Turkish law imposes a general duty to conclude a contract. A party is generally free not to sign. The doctrine instead targets dishonest negotiation behavior: entering talks without a real intention to contract, continuing negotiations only to extract information, causing unnecessary cost through misleading conduct, or abusing the trust created during the process. Turkish academic commentary citing Court of Cassation decisions reports that Turkish Supreme Court case-law has recognized responsibility where a party enters negotiations without the intention to conclude a contract and has also described negotiations as creating a trust relationship that requires care for the other party’s personal and property interests.
Misleading Information and the Duty to Inform
One of the clearest examples of bad-faith negotiation conduct is the giving of misleading information. Turkish academic writing on pre-contractual duties expressly identifies misrepresentation during negotiations as a major source of culpa in contrahendo liability. The recent 2025 Turkish study also highlights information duties and treats misleading conduct during negotiations as a central ground of pre-contractual responsibility.
This is especially important in commercial transactions. A seller may misstate the condition or legal status of an asset, a supplier may exaggerate production readiness, a licensor may overstate rights ownership, or a negotiating counterparty may distort its authority, solvency, or regulatory position. Even if the final contract is never signed, Turkish law may still protect the injured party if it reasonably relied on false or misleading negotiation-stage information and suffered loss as a result.
Confidentiality as a Pre-Contractual Duty
Confidentiality is another core issue in Turkish pre-contractual liability. The 2025 Turkish academic study specifically identifies the duty to maintain confidentiality as one of the important pre-contractual obligations discussed in Turkish legal analysis. That is commercially significant because modern negotiations often involve disclosure of customer lists, technical specifications, pricing formulas, internal financials, business strategies, and know-how before any final contract exists.
The legal logic is straightforward. Once negotiations create a relationship of trust, the receiving party should not use disclosed information in a way that harms the disclosing party. This is true even where a separate NDA exists, and it becomes even more important where no separate confidentiality agreement was signed. Turkish doctrine therefore treats confidentiality not merely as a side issue, but as part of the broader duty to negotiate and behave in good faith.
Bad-Faith Continuation or Break-Off of Negotiations
Pre-contractual liability in Turkey is not limited to lies. It can also arise from bad-faith continuation or break-off of negotiations. The 2025 Turkish study expressly discusses negotiations conducted in bad faith and treats bad-faith negotiation conduct as a significant legal mechanism of responsibility. The same study points to issues such as negotiation costs and exclusivity or non-parallel negotiation commitments, showing that Turkish analysis pays close attention to how one side structures and prolongs the process.
This does not mean that every broken negotiation is wrongful. Turkish law does not turn the failure to sign into automatic liability. What matters is whether the manner of continuing or ending negotiations was contrary to the principle of trust and good faith. For example, liability risk becomes stronger where one side intentionally creates confidence, induces expense or disclosure, and then withdraws in a way that appears manipulative rather than commercially honest.
The Protective Function of Trust and Reliance
The doctrine of culpa in contrahendo in Turkey is fundamentally based on trust. Turkish sources explain that the negotiation relationship can generate justified reliance and protected interests even before the contract exists. The doctrine protects against harm suffered because one party acted to its detriment during negotiations in reliance on the other party’s good-faith conduct.
That is why pre-contractual liability often centers on reliance loss rather than the full benefit the party hoped to obtain from the eventual contract. A recent Turkish academic article states that, as a rule, culpa in contrahendo compensation concerns negative or reliance loss, though equity may in exceptional situations justify a broader approach. The 2025 study also states that material and even moral damages may be discussed depending on the kind of negotiation-stage harm involved.
Typical Elements of a Pre-Contractual Liability Claim
Although Turkish law does not set out one statutory checklist, the doctrine repeatedly points to recurring elements. First, there must be a pre-contractual relationship. Second, a pre-contractual duty must have been breached, such as truthful information, confidentiality, honest negotiation, or careful handling of the other party’s trust. Third, the claimant must have suffered damage. Fourth, there must be a causal link between the negotiation misconduct and the loss. Fifth, fault remains relevant, especially where the general damages structure of the Turkish Code of Obligations is used. Turkish academic commentary summarizes these elements expressly.
This means pre-contractual liability is not a vague fairness slogan. The claimant still must show what happened, why it was wrong, how it caused loss, and why the law should shift that loss to the negotiating counterparty. Turkish law protects against wrongful negotiation conduct, not against the ordinary disappointment of a deal not closing.
Damages and Their Scope
On damages, Turkish sources are cautious but clear enough to guide practice. Professional and academic Turkish sources state that where good faith and due care are not respected in negotiations, compensation may be awarded according to the circumstances and equity. The 2025 Turkish study adds that both material and, in appropriate settings, moral damages may be discussed, while another recent Turkish academic article describes reliance loss as the normal baseline.
The statutory damages framework in Articles 49 to 52 of the Turkish Code of Obligations remains important here. Those provisions require proof of damage and fault, allow the judge to determine the form and amount of compensation, and permit reduction where the injured party contributed to the loss or worsened the other party’s position. This fits the logic of pre-contractual liability well: Turkish law seeks to compensate real harm caused by bad-faith negotiations without turning every failed deal into a substitute for the unrealized contract price.
Exclusivity, Parallel Negotiations, and Negotiation Costs
Modern Turkish scholarship also discusses parallel negotiations, exclusivity expectations, and negotiation costs as part of pre-contractual liability analysis. The 2025 Turkish study specifically notes that Turkish analysis of culpa in contrahendo addresses confidentiality, negotiation costs, and commitments not to conduct parallel negotiations.
This is particularly relevant in M&A, distributorship, technology licensing, and large supply or lease transactions. One side may incur advisor fees, reserve capacity, suspend talks with others, or provide sensitive information because it believes the process is exclusive or at least being handled honestly. If the other side manipulates that structure in bad faith, Turkish doctrine may treat the resulting loss as compensable.
Relationship With Invalid or Unconcluded Contracts
Pre-contractual liability in Turkey also matters where a contract is never concluded or where it is concluded but later proves invalid. Turkish legal writing explains that culpa in contrahendo is valuable precisely because it allows liability to arise from negotiation conduct itself, rather than depending entirely on the final enforceability of the contract. Without that doctrine, a party could sometimes escape responsibility by arguing that the contract never became valid in the first place. Turkish doctrine avoids that result by focusing on trust, good faith, and harmful reliance during negotiations.
Practical Drafting and Risk-Management Lessons
For parties negotiating under Turkish law, the first lesson is clarity. If talks are exploratory only, that should be stated. If exclusivity, cost allocation, confidentiality, or break-off procedures matter, they should be addressed expressly. Since Turkish doctrine is highly sensitive to trust and reliance, ambiguity about the structure of negotiations can create avoidable exposure.
The second lesson is information discipline. Factual, financial, regulatory, and technical statements made during negotiations should not be casual. Misleading information is one of the clearest sources of Turkish pre-contractual liability. Controlled disclosures, reservation language, and verification steps reduce risk significantly.
The third lesson is procedural consistency. If negotiations are no longer serious, they should not be prolonged in a way that creates false confidence and unnecessary cost for the other side. Turkish analysis of bad-faith negotiation conduct focuses strongly on manipulative continuation of talks and on abuse of the trust created by the process.
The fourth lesson is evidence preservation. Because these disputes are fact-intensive, emails, draft agreements, NDAs, advisor invoices, exclusivity texts, data-room records, and reservation notices can become decisive. Under the Turkish Code of Obligations, the claimant generally needs to show fault, damage, and causation, and under Turkish procedural law that requires concrete factual proof.
Conclusion
Pre-contractual liability in Turkey is a real and important doctrine, even though it is not contained in one express code article. Turkish law builds it mainly on Civil Code Article 2, which requires honest conduct and rejects abuse of rights, and then connects it to the broader Turkish law of obligations and damages. Turkish doctrine commonly describes this area as culpa in contrahendo and treats it as liability for bad-faith behavior during negotiations, especially where one party breaches duties of trust, truthful information, confidentiality, or careful dealing and thereby causes loss to the other side.
The doctrine does not mean that every unsuccessful negotiation becomes actionable. It means that Turkish law protects parties against dishonest negotiation conduct. Misleading information, trust abuse, confidentiality breaches, manipulative continuation of talks, and reliance-inducing bad faith can all lead to compensation even where no final contract is signed. The conceptual debate over whether the doctrine is contractual, tortious, or sui generis continues, but the practical legal message is already clear: under Turkish law, negotiations create duties, and bad-faith violation of those duties can generate liability.
FAQ
Is pre-contractual liability expressly regulated in Turkey?
No. Turkish legal doctrine generally derives culpa in contrahendo from the good faith principle in Article 2 of the Turkish Civil Code and connects it to the broader Turkish Code of Obligations and the general damages framework.
What is the main legal basis for pre-contractual liability in Turkey?
The main normative basis is Article 2 of the Turkish Civil Code, which requires everyone to comply with the rules of honesty while exercising rights and fulfilling obligations and states that manifest abuse of rights is not protected.
Does Turkish law punish every failed negotiation?
No. Turkish doctrine targets bad-faith negotiation conduct, not the mere fact that a final contract was not reached. Liability arises where negotiations are conducted dishonestly, misleadingly, or in a way that wrongfully harms the other party’s justified reliance.
What kinds of conduct can create liability?
Turkish sources highlight misleading information, breach of confidentiality, negotiations without real intention to contract, abuse of trust, bad-faith continuation or break-off of negotiations, and disputes over negotiation costs or parallel negotiations.
What kind of damages are usually discussed?
Turkish academic writing generally points to reliance loss as the normal measure, while also discussing material and, in some settings, moral damages. Articles 49 to 52 of the Turkish Code of Obligations provide the general framework for fault, damage, judicial assessment, and reduction.
Is the doctrine contractual or tortious?
Turkish scholarship is not fully unified. The main views described in Turkish sources are that pre-contractual liability is contractual, tortious, or sui generis, based on the trust relationship created during negotiations.
Can confidentiality duties exist before the contract is signed?
Yes. Turkish academic analysis of culpa in contrahendo specifically identifies confidentiality as one of the important pre-contractual duties that may arise during negotiations.
Why is evidence so important in these disputes?
Because the claimant typically must show the existence of a pre-contractual relationship, wrongful negotiation conduct, damage, causation, and fault. Under the general Turkish damages framework, those elements are fact-sensitive and require concrete proof.
