Introduction
Letters of intent and memoranda of understanding are widely used in Turkish commercial transactions before parties sign a final contract. They are common in mergers and acquisitions, joint ventures, share purchases, asset deals, real estate projects, international supply agreements, franchise negotiations, distribution arrangements, construction projects, technology transfers, investment rounds, financing transactions and settlement negotiations. In practice, an LOI or MOU often appears at the stage where the parties have reached a commercial understanding but are not yet ready to sign a complete, binding agreement.
The legal risk is that parties often treat these documents informally. A businessperson may believe that a letter of intent is only a “gentlemen’s agreement.” Another party may later argue that the same document created binding obligations. Under Turkish law, the answer depends on the wording of the document, the parties’ intention, the essential terms agreed, the nature of the transaction, conduct during negotiations, good faith principles and whether certain clauses were expressly drafted as binding.
Turkish contract law begins with party autonomy and mutual consent. Article 1 of the Turkish Code of Obligations provides that a contract is established when the parties mutually and concordantly express their will, and such expression may be express or implied. Article 2 also provides that if parties agree on the essential points of a contract, the contract is deemed established even if secondary points are not considered. This makes careful drafting essential. A document titled “non-binding LOI” may still create obligations if its language and content show that the parties intended to be bound on essential points.
This article explains the legal effect of letters of intent and memoranda of understanding in Turkish commercial transactions, including their binding and non-binding elements, preliminary agreements, confidentiality clauses, exclusivity obligations, good faith negotiation duties, pre-contractual liability, dispute risks and drafting strategies.
1. What Is a Letter of Intent?
A letter of intent is a pre-contractual document that records the main commercial understanding between parties before a final contract is signed. It may summarize proposed price, transaction structure, due diligence process, exclusivity, confidentiality, timeline, closing conditions, governing law, dispute resolution, cost allocation and next steps.
In Turkish legal practice, a letter of intent is generally not treated as a final contract if the parties clearly express that they do not intend to be bound until a definitive agreement is signed. Turkish legal commentary explains that an LOI is generally not considered a legally binding document because the party issuing it usually does not intend to be bound, while a binding contract requires mutual declaration of will.
However, “generally non-binding” does not mean “legally irrelevant.” Certain provisions within an LOI may be binding, such as confidentiality, exclusivity, governing law, dispute resolution, cost sharing, due diligence access, return of documents and non-solicitation clauses. The key is whether the parties intended those clauses to have legal effect.
2. What Is a Memorandum of Understanding?
A memorandum of understanding is similar to a letter of intent but is often drafted as a more structured document signed by both parties. In commercial practice, an MOU may record a broader framework for cooperation, investment, project development, distribution, joint venture, licensing, construction or strategic partnership.
The difference between an LOI and MOU is not always legally decisive under Turkish law. Courts and arbitral tribunals will examine the content, not only the title. A document called “Memorandum of Understanding” may be non-binding if it only records negotiation principles. A document called “Letter of Intent” may be partially or fully binding if it contains clear commitments and essential contractual terms.
Therefore, the safest approach is to state expressly which provisions are binding and which are not. For example, the document may say: “Except for Articles 5, 6, 7 and 10 concerning confidentiality, exclusivity, costs and governing law, this MOU is not intended to create legally binding obligations.”
3. LOI and MOU under Turkish Contract Law
Turkish law does not regulate letters of intent and memoranda of understanding as separate named contracts. Their legal effect is determined under general contract law, especially the Turkish Code of Obligations, Turkish Civil Code good faith principles and Turkish Commercial Code rules where the parties are merchants.
The Turkish Code of Obligations recognizes that contracts may be formed expressly or implicitly, and that agreement on essential terms may be sufficient for contract formation. This creates a real risk in commercial negotiations. If an LOI includes clear agreement on essential points such as parties, subject matter, price, delivery, quantity and performance obligations, and if the language suggests final commitment, one party may later argue that a binding contract was already formed.
On the other hand, where the LOI clearly states that the transaction is subject to due diligence, board approval, financing, final documentation and execution of a definitive agreement, it is easier to argue that no final contract exists.
4. Preliminary Agreement under Turkish Code of Obligations Article 29
A letter of intent must be distinguished from a preliminary agreement. Article 29 of the Turkish Code of Obligations provides that agreements concerning the future establishment of a contract are valid. It also provides that, except for legal exceptions, the validity of the preliminary agreement depends on the form of the contract to be established in the future.
This rule is very important. A preliminary agreement is more binding than a simple LOI. It creates an obligation to enter into a future contract. For example, if parties sign a valid preliminary share purchase agreement, real estate promise, asset transfer commitment or future supply agreement, one party may claim that the other must complete the final contract or compensate damages.
The form requirement is also critical. If the future contract is subject to a special form requirement, the preliminary agreement may need to satisfy that form as well. Turkish legal commentary on Article 29 emphasizes that the validity of a pre-contract depends on the form of the future contract, except where the law provides otherwise.
Therefore, parties should not casually label an LOI as a “preliminary agreement” unless they truly intend to create a binding obligation to sign a later contract.
5. Binding and Non-Binding Clauses
In Turkish commercial practice, LOIs and MOUs are often hybrid documents. The main transaction may be non-binding, while specific clauses are binding.
Common binding clauses include:
Confidentiality.
Exclusivity.
Non-solicitation.
Due diligence access.
Cost allocation.
Return or destruction of documents.
Data protection obligations.
Public announcement restrictions.
Governing law.
Dispute resolution.
Break-up fee or penalty clause.
No-shop obligation.
Standstill obligation.
Common non-binding clauses include:
Indicative purchase price.
Proposed transaction structure.
Target closing date.
Non-final commercial terms.
Draft supply quantities.
Preliminary investment assumptions.
Indicative valuation.
Proposed governance principles.
The document should not leave this distinction ambiguous. If the parties intend only selected clauses to bind them, those provisions should be listed expressly. Legal commentary on Turkish law similarly notes that while an LOI is generally non-binding, explicit binding terms such as confidentiality obligations may be enforceable.
6. The Role of Good Faith in Turkish Negotiations
Good faith is central in Turkish law. Article 2 of the Turkish Civil Code provides that everyone must comply with the rules of honesty when exercising rights and fulfilling obligations, and that the legal order does not protect the abuse of a right.
This principle affects pre-contractual negotiations. Even if an LOI is non-binding, parties are not completely free to act dishonestly. A party may incur liability if it negotiates in bad faith, provides false information, abruptly breaks off advanced negotiations without legitimate reason after creating justified reliance, misuses confidential information, conceals material facts, or causes the other party to incur unnecessary expenses through misleading conduct.
This is often discussed under the concept of culpa in contrahendo, or pre-contractual liability. Turkish legal commentary explains that the pre-contractual stage is governed by good faith and by liability for breach of pre-contractual obligations; representations made in term sheets, letters of intent or email negotiations may create liability if they are inaccurate or misleading.
7. When Can a Non-Binding LOI Still Create Liability?
A non-binding LOI may still create liability in several situations.
First, binding clauses may be breached. If a party violates confidentiality, exclusivity, non-solicitation or cost-sharing clauses, the other party may claim damages or seek injunctions.
Second, one party may act contrary to good faith. For example, a buyer may enter negotiations only to obtain trade secrets, customer data or pricing information with no real intention to transact. A seller may invite due diligence while secretly negotiating an exclusive sale with another buyer, despite a no-shop clause.
Third, one party may make false representations. If a party provides inaccurate financial, technical, legal or regulatory information and the other party relies on it, pre-contractual liability may arise.
Fourth, the LOI may be drafted so strongly that it is interpreted as a binding contract. If the document contains essential terms and uses mandatory language such as “shall sell,” “shall purchase,” “the parties hereby agree,” and “closing shall occur,” the title “LOI” may not save it from binding effect.
8. Contract Formation Risk: Essential Terms
The most dangerous drafting risk is unintended contract formation. Under Turkish Code of Obligations Article 2, agreement on essential terms may be enough for contract formation even if secondary issues remain unresolved.
For a sale of goods, essential terms may include parties, subject matter, quantity and price or price determination mechanism. For a share purchase, essential terms may include seller, buyer, shares, price and transfer mechanism. For a lease, essential terms may include property, term and rent. For a distribution agreement, essential terms may include territory, products, exclusivity and core obligations.
If parties want to avoid binding effect, they should state that no definitive agreement will exist unless and until a final written contract is negotiated, approved and signed by authorized representatives. They should also avoid language suggesting final obligation.
9. Authority and Corporate Approval
In Turkish commercial transactions, signature authority is crucial. A company may only be bound by persons authorized to represent it, subject to Turkish company law, trade registry records and internal approval rules. In M&A, joint venture and financing negotiations, an LOI may also be subject to board approval, shareholder approval, investment committee approval, bank approval or regulatory clearance.
The LOI should state whether signatories have authority to bind the parties and whether final transaction obligations remain subject to corporate approvals. If a representative signs without authority, disputes may arise regarding apparent authority, internal approval, reliance and damages.
For foreign companies, the Turkish counterparty’s trade registry records and signature circular should be checked before signing even a preliminary document. A non-binding LOI may still include binding confidentiality or exclusivity clauses, so authority matters.
10. Confidentiality Clauses
Confidentiality is one of the most important binding clauses in an LOI or MOU. During negotiations, parties may exchange financial statements, customer lists, trade secrets, technical drawings, business plans, pricing, supplier data, employee information, IP documents, tax records and strategic information.
A confidentiality clause should define confidential information broadly, identify permitted use, restrict disclosure, regulate advisors’ access, impose return or destruction obligations, protect trade secrets, cover copies and notes, and survive termination of negotiations.
The clause should also address whether disclosure is permitted to affiliates, banks, auditors, lawyers, consultants, investors or regulatory authorities. If personal data is shared during due diligence, Turkish data protection rules may also become relevant.
A weak confidentiality clause may leave the disclosing party exposed if negotiations fail and the recipient uses the information competitively.
11. Exclusivity and No-Shop Clauses
Exclusivity clauses are common in M&A, investment, real estate, franchise, distribution and project development LOIs. A buyer may request that the seller not negotiate with other buyers for a defined period. A potential distributor may request territorial exclusivity while due diligence continues. A franchisor may agree not to appoint another franchisee during site evaluation.
An exclusivity clause should define:
The exclusivity period.
The covered transaction.
Restricted communications.
Permitted exceptions.
Obligation to notify competing offers.
Remedies for breach.
Whether injunctive relief is available.
Whether a break-up fee applies.
Exclusivity should not be indefinite. A long or vague exclusivity clause may create commercial and competition-law issues. It should be tied to a legitimate negotiation period and a clear transaction.
12. Cost Allocation and Break-Up Fees
LOIs often state that each party bears its own costs. This is useful because due diligence, legal review, tax advice, technical inspection, valuation, travel and translation costs can be substantial.
In some transactions, parties may agree to a break-up fee. A break-up fee may be payable if one party walks away after a certain stage, breaches exclusivity, fails to obtain approval, or chooses another bidder. Under Turkish law, such clauses must be drafted carefully, especially if they function as penalty clauses or liquidated damages.
The amount should be commercially reasonable and proportionate. Excessive penalty clauses may be subject to judicial reduction under Turkish law in certain circumstances. A break-up fee should not be drafted as punishment for legitimate refusal to sign a final agreement unless the parties clearly intend such risk allocation and it is legally defensible.
13. Due Diligence and Document Access
In commercial transactions, an LOI often opens the due diligence process. The seller or target grants access to financial, legal, tax, operational, technical and commercial documents. This access must be controlled.
The LOI should regulate:
Scope of due diligence.
Data room access.
Authorized reviewers.
Use of documents.
Confidentiality.
Personal data limitations.
Copying restrictions.
Document return or destruction.
Management interviews.
Site visits.
Third-party consents.
No reliance or reliance provisions.
If the buyer will rely on disclosed information, this should be addressed in the definitive agreement through representations, warranties and disclosure schedules. The LOI should not accidentally create broad warranties unless intended.
14. Data Protection in LOI and MOU Processes
Due diligence often involves personal data: employee lists, payroll, customer databases, supplier contacts, litigation files, contracts, e-mails, HR records and compliance reports. In Turkey, sharing personal data during negotiations may trigger obligations under the Personal Data Protection Law No. 6698.
The LOI or a separate data processing agreement should regulate whether personal data may be shared, whether anonymization or redaction is required, who may access it, how it will be stored, whether it may be transferred abroad and when it must be deleted.
Cross-border due diligence is especially sensitive where a foreign buyer accesses Turkish employee or customer data. A data room should not become an uncontrolled data transfer mechanism.
15. Governing Law and Dispute Resolution
Even a non-binding LOI may need governing law and dispute resolution clauses because binding clauses can create disputes. For example, if confidentiality or exclusivity is breached, the injured party must know where to sue or arbitrate.
The LOI should state whether Turkish law or another law applies. In Turkey-related transactions, Turkish law may be preferable where the counterparty, assets, evidence or interim measures are in Turkey. Arbitration may be preferable in cross-border transactions requiring confidentiality and neutrality.
If the LOI contains binding clauses and a dispute arises over monetary compensation, mandatory mediation may also become relevant for certain commercial lawsuits. Article 5/A of the Turkish Commercial Code makes mediation a precondition for commercial lawsuits concerning monetary receivables and compensation claims within its scope.
The dispute resolution clause should also preserve the right to seek interim injunctions before competent courts for confidentiality, exclusivity, IP misuse or evidence preservation.
16. LOI in M&A Transactions
LOIs are particularly common in Turkish M&A transactions. A buyer and seller may use an LOI to agree on valuation range, transaction structure, due diligence, exclusivity, confidentiality, closing conditions, regulatory approvals, escrow, representations, warranties and expected timeline.
However, M&A LOIs are high-risk documents. If the wording is too definitive, the seller may argue that the buyer committed to purchase. If the LOI is too vague, the buyer may lack exclusivity and spend due diligence costs while the seller negotiates with others.
A well-drafted M&A LOI should state that the transaction remains subject to due diligence, board approval, negotiation of definitive agreements, regulatory approvals and satisfaction of closing conditions. Binding clauses should be expressly identified.
17. LOI in Real Estate and Construction Projects
Letters of intent are frequently used in Turkish real estate and construction projects, including hotel development, build-to-suit projects, lease negotiations, construction contracts, land development, investment projects and contractor selection.
Special caution is required where the future agreement is subject to a statutory form requirement. For example, certain real estate-related promises may require official form. Since Article 29 of the Turkish Code of Obligations links the form of a preliminary agreement to the future contract’s required form, a simple signed LOI may not be sufficient for some real estate obligations.
In construction projects, an LOI may authorize early works before the final contract. This is risky unless scope, price, payment, insurance, site responsibility, health and safety, termination and liability are clearly regulated. Otherwise, disputes may arise over whether the contractor was entitled to payment for early works.
18. LOI in Distribution, Franchise and Agency Negotiations
In distribution, franchise and agency negotiations, an LOI may cover proposed territory, exclusivity, brand use, franchise fee, sales targets, training, supply obligations, market launch timeline and confidentiality.
The main risk is premature market reliance. A potential franchisee may lease premises, hire employees and invest in decoration before the final franchise agreement is signed. A potential distributor may begin contacting customers and promoting the brand. If negotiations fail, both sides may claim losses.
The LOI should expressly state whether the potential partner may begin operations, use trademarks, contact customers, make public announcements or incur expenses. If no such authority exists, the LOI should say so clearly.
19. MOU in Joint Venture and Strategic Partnership Transactions
MOUs are common in joint venture and strategic partnership transactions. They may record business objectives, capital contribution expectations, governance principles, market strategy, IP contributions, financing needs, management structure and future documentation.
A joint venture MOU can easily become ambiguous. One party may treat it as a moral framework, while the other treats it as a binding roadmap. The MOU should therefore distinguish between commercial intentions and legal obligations.
In joint venture negotiations, the parties should be careful with statements about capital contributions, exclusivity, IP transfer, customer allocation and non-compete obligations. These may create future claims or competition-law issues if poorly drafted.
20. Practical Drafting Language
A non-binding LOI may include language such as:
“This Letter of Intent is intended solely as a statement of the parties’ current intentions and does not create any obligation to complete the proposed transaction, except for the provisions expressly stated to be binding.”
A binding clause section may say:
“Articles 6, 7, 8, 9 and 12 concerning confidentiality, exclusivity, costs, governing law and dispute resolution shall be legally binding upon the parties.”
A no-contract clause may say:
“No party shall be bound to complete the proposed transaction unless and until a definitive written agreement is negotiated, approved by the relevant corporate bodies and duly executed by authorized representatives of both parties.”
Such wording reduces ambiguity. It does not eliminate all good-faith liability, but it helps prevent unintended final contract formation.
21. Common Drafting Mistakes
The most common mistakes in LOIs and MOUs in Turkish commercial transactions include:
Using binding language in a supposedly non-binding document.
Failing to identify which clauses are binding.
Forgetting confidentiality obligations.
Granting exclusivity without a time limit.
Failing to address cost allocation.
Allowing due diligence access without data protection controls.
Using “preliminary agreement” language unintentionally.
Ignoring form requirements under Turkish law.
Failing to include corporate approval conditions.
Failing to verify signatory authority.
Contradicting the LOI with later e-mails or conduct.
Failing to preserve the right to seek interim injunctions.
Using foreign templates without Turkish law review.
These mistakes can transform a negotiation document into a source of litigation.
22. Practical Checklist for Turkish Commercial LOIs and MOUs
Before signing an LOI or MOU in a Turkish commercial transaction, parties should ask:
Is the document intended to be binding, non-binding or partially binding?
Which clauses are legally binding?
Are essential transaction terms too definitive?
Is the document subject to board or shareholder approval?
Are signatories authorized?
Does the future contract require special form?
Is confidentiality adequately protected?
Is exclusivity necessary and time-limited?
Are costs and break-up fees regulated?
Is due diligence access controlled?
Is personal data protected?
Is public announcement restricted?
Are governing law and dispute resolution clear?
Is interim relief available?
Does the document contradict prior or future correspondence?
A short LOI may create long litigation if these questions are ignored.
Conclusion
Letters of intent and memoranda of understanding in Turkish commercial transactions are useful tools for structuring negotiations, recording commercial expectations and organizing due diligence. However, they are not legally harmless. Under Turkish law, a contract may arise when parties mutually express their will on essential terms, and good faith applies during negotiations. A document labeled “LOI” or “MOU” may be non-binding, partially binding or, in some cases, effectively binding depending on its wording and context.
The safest drafting approach is clarity. The document should expressly state whether it is binding or non-binding, identify binding provisions, reserve final contract formation until execution of definitive agreements, include corporate approval conditions, regulate confidentiality and exclusivity, control due diligence access, protect personal data, allocate costs and define dispute resolution.
For Turkish and foreign companies, LOIs and MOUs should not be treated as casual business letters. They are legal instruments that can shape liability, negotiation leverage and future disputes. A carefully drafted LOI can protect negotiations; a careless one can create unintended contractual obligations, compensation claims and commercial uncertainty.
Frequently Asked Questions
Are letters of intent binding under Turkish law?
Generally, a letter of intent is not binding if it only records the parties’ intention to negotiate and clearly states that no final contract exists. However, specific clauses such as confidentiality, exclusivity, cost allocation and dispute resolution may be binding.
Can an MOU be legally binding in Turkey?
Yes. An MOU may be binding, non-binding or partially binding depending on its wording, content and the parties’ intention. Turkish law examines substance rather than title.
What is the main legal risk of an LOI in Turkey?
The main risk is unintended binding effect. If the LOI contains essential terms and uses language showing final commitment, one party may argue that a contract was already formed under Turkish Code of Obligations principles.
What is a preliminary agreement under Turkish law?
A preliminary agreement is an agreement to conclude a future contract. Article 29 of the Turkish Code of Obligations provides that such agreements are valid, and their validity generally depends on the form required for the future contract.
Is good faith relevant during negotiations in Turkey?
Yes. Article 2 of the Turkish Civil Code requires parties to act according to honesty and good faith when exercising rights and fulfilling obligations. This principle may affect pre-contractual conduct.
Can a party be liable for breaking off negotiations?
Possibly. A party is generally free not to sign a final contract, but liability may arise if it acts in bad faith, misleads the other party, breaches confidentiality or creates justified reliance through dishonest conduct.
Should an LOI include confidentiality clauses?
Yes. Confidentiality clauses are essential, especially in M&A, joint venture, franchise, supply and technology transactions where trade secrets, financial data, customer information or personal data may be shared.
Should exclusivity clauses be binding?
Usually, yes, if exclusivity is commercially important. The clause should define the exclusivity period, scope, exceptions and remedies for breach.
Can an LOI be subject to Turkish mandatory mediation?
If a dispute arises from binding provisions and the claim is a commercial monetary receivable or compensation claim within Article 5/A of the Turkish Commercial Code, mandatory mediation may be required before filing a lawsuit.
What is the best drafting practice for LOIs and MOUs in Turkey?
The best practice is to state expressly which clauses are binding, which are non-binding, that no final transaction obligation exists until a definitive agreement is signed, and that all binding clauses are governed by a clear law and dispute resolution mechanism.
