Introduction
Turkey has long been one of the most strategically positioned jurisdictions for international commerce, foreign direct investment, logistics, manufacturing, construction, technology, energy, infrastructure, real estate and regional trade. Located between Europe, Asia, the Middle East, North Africa and the Caucasus, Turkey functions as a commercial bridge for foreign investors who wish to access multiple markets through one operational base.
For foreign investors, however, market opportunity must always be evaluated together with legal certainty. Entering the Turkish market without understanding Turkish international commercial law may result in contractual disputes, tax exposure, customs penalties, shareholder conflicts, regulatory problems, payment risks, enforcement difficulties and jurisdictional uncertainty. Therefore, a foreign investor should not only ask whether Turkey is commercially attractive, but also how the investment will be legally structured, protected, operated and, if necessary, enforced.
Turkish international commercial law is not limited to one statute. It is a broad legal framework formed by the Turkish Commercial Code, Turkish Code of Obligations, Foreign Direct Investment Law, private international law rules, customs legislation, tax regulations, competition law, employment law, banking and foreign exchange rules, arbitration law and enforcement mechanisms. The Turkish Commercial Code No. 6102 entered into force on 1 July 2012 and contains core provisions on commercial enterprises, companies, unfair competition, trade names, negotiable instruments, transportation and other commercial matters.
This guide explains the main legal issues foreign investors should consider before doing business in Turkey. It focuses on practical commercial risks and legal tools, including company establishment, international contracts, choice of law, jurisdiction, arbitration, customs compliance, payment security, foreign judgment enforcement and protection of foreign investment.
Why Turkey Matters for Foreign Investors
Turkey offers foreign investors a large domestic market, access to regional supply chains, a young workforce, manufacturing capacity, developed logistics infrastructure and proximity to important export destinations. According to the official Investment Office, Turkey attracted around USD 288 billion of foreign direct investment during the 2003–2025 period, and the number of companies with international capital reached 86,926 as of mid-2025.
These figures show that foreign investment in Turkey is not exceptional or unusual. It is a normal part of the Turkish commercial environment. Foreign-owned companies operate in sectors such as manufacturing, finance, automotive, logistics, energy, technology, real estate, retail, tourism, pharmaceuticals, construction and professional services.
However, foreign investors should distinguish between commercial access and legal preparedness. Turkey is open to foreign investment, but investors must still comply with sector-specific rules, trade registry procedures, tax obligations, customs requirements, employment regulations, personal data rules and dispute resolution procedures. The legal framework is investor-friendly in many respects, but it is also formal, document-driven and procedure-sensitive.
Legal Basis of Foreign Investment in Turkey
The main statute governing foreign direct investment is Foreign Direct Investment Law No. 4875. Under this law, foreign investors may establish a new company or branch in Turkey or acquire shares in an existing Turkish company. Foreign investors include foreign real persons, Turkish nationals residing abroad, foreign legal entities and international institutions that make foreign direct investment in Turkey.
One of the most important principles under Turkish foreign investment law is national treatment. Unless otherwise provided by international agreements or special laws, foreign investors are free to make foreign direct investments in Turkey and are subject to equal treatment with domestic investors. The law also protects foreign direct investments from expropriation or nationalisation except for public interest and upon compensation in accordance with due process of law.
Another important protection concerns transfer rights. Foreign investors may generally transfer abroad net profits, dividends, proceeds from sale or liquidation, compensation payments, amounts arising from license or management agreements, and payments related to foreign loans through banks or special financial institutions.
These principles are highly relevant for international investors. They mean that Turkey does not require foreign investors to operate only through local nominees or Turkish majority shareholders as a general rule. Nevertheless, certain regulated sectors may still contain special rules or limitations, especially in areas such as broadcasting, maritime, aviation, financial services, energy, mining, defense, telecommunications and public procurement.
Choosing the Right Legal Structure in Turkey
A foreign investor may operate in Turkey through different legal structures. The most common options are joint stock companies, limited liability companies, branches, liaison offices and joint ventures. The correct structure depends on the investor’s commercial goals, liability concerns, tax planning, corporate governance expectations, financing model and exit strategy.
A joint stock company, known as “anonim şirket”, is often preferred for medium and large-scale investments. It is suitable for investors who plan to create different share groups, attract external financing, issue shares, establish detailed corporate governance mechanisms or prepare for a future sale. Joint stock companies are also more familiar to international investors due to their flexible shareholding and management structure.
A limited liability company, known as “limited şirket”, is commonly used for smaller and medium-sized businesses. It is easier to operate in some respects and may be appropriate for service businesses, trading companies, local subsidiaries and family-controlled investments. However, share transfer procedures and governance flexibility may differ from joint stock companies.
The official Investment Office notes that joint ventures in Turkey are generally considered ordinary partnerships, which do not have separate legal personality under Turkish law, although parties often prefer to establish a commercial company for the joint venture. It also states that there are generally no nationality restrictions on shareholders or persons holding management rights, except in certain specific sectors such as TV broadcasting, maritime and civil aviation.
A branch office may be appropriate where the foreign parent company wishes to conduct commercial activities in Turkey without establishing a separate subsidiary. However, a branch is not an independent legal entity and generally operates within the scope and duration of the parent company. A liaison office, on the other hand, may be useful for market research, representation and coordination, but it cannot engage in commercial activities in Turkey.
Company Formation and Trade Registry Compliance
Foreign investors must pay close attention to Turkish trade registry requirements. Company formation in Turkey is document-heavy and requires proper preparation of articles of association, shareholder resolutions, notarized and apostilled/legalized corporate documents, tax registration, signature authorities, capital commitments and registration filings.
For foreign corporate shareholders, documents issued abroad usually need to be apostilled or legalized, translated into Turkish and notarized in Turkey. Powers of attorney must be carefully drafted because Turkish authorities, banks, notaries and trade registry offices may require specific authority wording. A general commercial power of attorney that works in another jurisdiction may not be sufficient for Turkish procedures.
After incorporation, companies must comply with bookkeeping, tax, social security, employment, beneficial ownership, licensing and notification obligations. Foreign-owned companies may also be required to submit certain foreign direct investment information electronically through the E-TUYS system. The Investment Office explains that FDI activity, capital and share transfer data forms are received electronically through E-TUYS rather than in printed form.
Corporate governance should not be treated as a formality. In Turkey, company authority is closely connected to trade registry records, signature circulars, board decisions, manager decisions and articles of association. Before signing any commercial contract, a foreign investor should verify whether the Turkish counterparty’s representative is duly authorized.
International Commercial Contracts in Turkey
International commercial contracts are the foundation of foreign investment and cross-border trade. A foreign investor may enter into sales contracts, supply agreements, distribution agreements, agency contracts, franchise contracts, construction agreements, EPC contracts, service agreements, licensing agreements, technology transfer agreements, logistics contracts, shareholder agreements or financing arrangements.
A Turkey-related international contract should clearly regulate the identity of the parties, authority of signatories, scope of goods or services, price, currency, tax responsibilities, delivery terms, Incoterms, customs responsibilities, payment schedule, bank charges, inspection procedures, warranty obligations, limitation of liability, penalty clauses, force majeure, hardship, termination, confidentiality, intellectual property, governing law, jurisdiction or arbitration, evidence, notices and language priority.
Foreign investors frequently make the mistake of relying on short commercial documents, proforma invoices or informal correspondence instead of comprehensive contracts. This may be risky in Turkey because commercial disputes are strongly evidence-based. Turkish courts and arbitral tribunals usually examine written contracts, invoices, delivery documents, correspondence, customs records, payment receipts, bank transfers, expert reports and commercial books.
In international sale of goods transactions, investors should also consider the United Nations Convention on Contracts for the International Sale of Goods, known as the CISG. Turkey became a party to the CISG, and the Convention entered into force for Turkey on 1 August 2011. Therefore, in many cross-border sale of goods contracts involving Turkish parties, the CISG may apply unless the parties validly exclude it.
Choice of Law in Turkey-Related Transactions
Choice of law is one of the most important questions in Turkish international commercial law. Parties to a contract with a foreign element may generally choose the law applicable to their contractual relationship. For example, a Turkish company and a foreign supplier may choose Turkish law, English law, Swiss law or another legal system depending on the nature of the transaction.
However, a choice-of-law clause must be drafted carefully. A vague clause such as “international law shall apply” is usually problematic because there is no single body of private “international law” automatically governing all commercial contracts. The parties should identify a specific governing law and ensure that the dispute resolution clause is compatible with that choice.
Turkish private international law is mainly governed by Law No. 5718 on International Private and Procedure Law, which entered into force on 12 December 2007. This law provides the framework for foreign-element private law disputes, including applicable law, international jurisdiction and recognition and enforcement of foreign judgments.
Even where foreign law is chosen, mandatory Turkish rules may still become relevant. For example, rules concerning customs, tax, employment, real estate, competition, consumer protection, data protection, capital markets or public order may apply regardless of the contractual governing law. Therefore, foreign investors should not assume that selecting foreign law completely removes Turkish legal risk.
Jurisdiction Clauses and Turkish Courts
A foreign investor should decide at the contract stage where disputes will be resolved. The options usually include Turkish courts, foreign courts, domestic arbitration, international arbitration or institutional arbitration.
Turkish commercial courts are commonly used for disputes involving Turkish companies, unpaid invoices, shareholder conflicts, unfair competition, negotiable instruments, commercial debt, contractual termination and damages. In certain commercial receivable disputes, mandatory mediation may be required before filing a lawsuit. Failure to complete mandatory mediation where required may result in procedural dismissal.
Jurisdiction clauses should be drafted clearly. If the parties want Turkish courts to have exclusive jurisdiction, the clause should say so. If they want a foreign court to have jurisdiction, the enforceability of the future foreign judgment in Turkey should be considered. If the counterparty has assets in Turkey, choosing a foreign court may create an additional enforcement stage before Turkish execution proceedings can begin.
Foreign investors should also consider the possibility of interim measures. If assets, goods, receivables or evidence are located in Turkey, Turkish courts may be relevant even where the main dispute is subject to foreign jurisdiction or arbitration. Attachment, injunction, evidence preservation and interim relief strategies should be planned before a dispute escalates.
International Arbitration in Turkey
Arbitration is a major dispute resolution mechanism in Turkey-related international commercial transactions. It is especially common in construction, infrastructure, energy, distribution, shareholder, international sale of goods, logistics and technology disputes.
International arbitration in Turkey is mainly governed by International Arbitration Law No. 4686 where the dispute has a foreign element and Turkey is the seat of arbitration, or where the parties choose the application of that law. A valid arbitration agreement should be in writing and should clearly demonstrate the parties’ intention to submit disputes to arbitration. Turkish arbitration practice places importance on clarity because contradictory clauses may cause jurisdictional disputes.
The arbitration clause should specify the arbitral institution, seat of arbitration, number of arbitrators, language, governing law, procedural rules and scope of disputes covered. A clause that merely says “disputes shall be resolved by arbitration” may be insufficient or may create unnecessary procedural conflict.
Not every dispute is arbitrable. Under Turkish arbitration principles, disputes concerning rights in rem over immovable property in Turkey and matters that do not depend solely on the will of the parties are generally considered non-arbitrable. For this reason, foreign investors should obtain legal review before placing arbitration clauses in contracts involving real estate, employment, consumer relationships, administrative permits or public law elements.
Recognition and Enforcement of Foreign Judgments and Arbitral Awards
Foreign investors often assume that winning a lawsuit or arbitration abroad is the end of the dispute. In practice, if the losing party’s assets are in Turkey, the investor may need recognition or enforcement proceedings before Turkish courts.
A foreign court judgment is not automatically enforceable in Turkey. The successful party must generally file an enforcement action before the competent Turkish court. The Turkish court will not normally retry the merits of the foreign dispute, but it will examine statutory conditions such as finality, jurisdiction, due process, proper service, public order and reciprocity where applicable.
Foreign arbitral awards are often more practical from an enforcement perspective because Turkey is a party to the New York Convention. Nevertheless, enforcement of a foreign arbitral award in Turkey still requires court proceedings if the losing party does not voluntarily comply. The resisting party may raise limited objections, such as invalidity of the arbitration agreement, lack of due process, excess of authority, non-arbitrability or violation of public order.
For foreign investors, the key lesson is simple: dispute resolution clauses should be drafted with enforcement in mind. The best forum is not always the forum that seems convenient at the beginning. The correct question is: where are the assets, how quickly can interim measures be obtained, and how enforceable will the final decision be?
Customs, Import and Export Compliance
Foreign investors engaged in manufacturing, trading, logistics, e-commerce, distribution or industrial projects must pay close attention to Turkish customs law. Customs compliance is not merely an operational matter; it is a legal risk area that may directly affect profitability, delivery, penalties and dispute exposure.
Importers should correctly determine HS codes, customs value, country of origin, applicable customs duties, additional financial obligations, anti-dumping measures, product safety requirements, permits, quotas, CE marking, health certificates and technical standards. The Turkish Ministry of Trade explains that customs duty is determined by the Import Regime, published in the Official Gazette at the end of the year and entering into force at the beginning of the following year.
Documentation is equally important. Commercial shipments to Turkey generally require documents such as a commercial invoice, bill of lading or airway bill, packing list and certificate of origin, while additional documents may be necessary depending on the product’s tariff code and nature.
A foreign investor should ensure that its commercial contract clearly allocates responsibility for customs clearance, import permits, duties, taxes, storage charges, demurrage, delayed delivery, rejected goods and regulatory non-compliance. Many disputes arise not because the parties disagree on the price, but because they failed to determine who bears customs and logistics risks.
Payment Security and Financial Risk
Payment risk is one of the most common problems in international commercial transactions involving Turkey. Foreign investors may face delayed payments, currency fluctuations, bank transfer issues, withholding tax problems, documentary discrepancies, sanctions screening, foreign exchange restrictions or insolvency risks.
To reduce these risks, contracts should include clear payment terms, currency provisions, interest for late payment, default procedures, documentary conditions, bank guarantee mechanisms, letters of credit, escrow arrangements, retention clauses and title retention where legally appropriate. In high-value transactions, advance payment alone may not be sufficient, while open account sales may be too risky without credit insurance or security.
Bank guarantees and letters of credit are commonly used in Turkey-related international trade. However, the exact wording of the guarantee is crucial. Investors should distinguish between conditional guarantees, demand guarantees, performance bonds, advance payment guarantees and letters of credit. The legal consequences may vary significantly depending on the wording and applicable law.
Foreign investors should also preserve evidence of payment. Bank receipts, SWIFT messages, invoices, reconciliation records, account statements and correspondence should be stored carefully. In Turkish commercial litigation, proving payment or non-payment often depends on documentary evidence.
Shareholder Agreements and Joint Ventures
Foreign investors frequently enter Turkey through joint ventures with local partners. A local partner may provide market knowledge, licenses, land, customer access, distribution channels, workforce or public-sector relationships. However, joint ventures may also create serious risks if governance is not carefully structured.
A shareholder agreement should regulate capital contributions, shareholding percentages, management rights, board composition, reserved matters, veto rights, dividend policy, financing obligations, deadlock mechanisms, share transfers, drag-along rights, tag-along rights, non-compete obligations, confidentiality, intellectual property, exit rights and dispute resolution.
Foreign investors should understand that a private shareholder agreement may not always be sufficient unless the articles of association, board resolutions and trade registry records are aligned with it. In Turkish company practice, corporate authority and third-party effect often depend on formal registration and company documents.
Deadlock clauses are particularly important. If two partners hold equal shares and cannot agree on major decisions, the company may become commercially paralyzed. Foreign investors should therefore include clear deadlock resolution tools, such as escalation meetings, buy-sell mechanisms, Russian/Texas shoot-out clauses, put/call options or arbitration.
Employment, Work Permits and Key Personnel
Foreign investors who want to appoint foreign managers, engineers, executives or technical personnel must consider work permit requirements. A foreigner who intends to work in Turkey must generally obtain a work permit from the Ministry of Labor and Social Security, and work permits may be temporary, permanent or independent depending on the circumstances.
The official Investment Office explains that work permit applications are submitted through the E-Permit system and that domestic applications are generally made by the employer. Foreign investors should plan work permit timing carefully because a foreign executive may not be able to legally work in Turkey merely because they are a shareholder or board member.
Employment contracts should comply with Turkish labor law, social security obligations, payroll requirements, termination rules, overtime, annual leave and workplace health and safety rules. For senior executives, additional provisions may be needed regarding confidentiality, non-compete obligations, intellectual property, performance targets, bonuses and termination compensation.
Practical Legal Checklist for Foreign Investors
Before entering the Turkish market, a foreign investor should conduct legal due diligence. This includes reviewing sectoral restrictions, required licenses, tax structure, customs exposure, counterparty authority, trade registry records, real estate status, employment implications, data protection obligations and dispute resolution strategy.
Before signing a contract, the investor should verify the Turkish counterparty’s company status, authorized signatories, financial capacity, litigation history, tax status and commercial reputation. If the contract involves goods, the investor should check customs classification, import permits, product safety rules and delivery terms.
Before transferring funds, the investor should confirm the payment channel, recipient account, tax consequences, withholding obligations, currency restrictions and supporting documentation. Before appointing a local partner, the investor should negotiate a strong shareholder agreement and ensure that company documents reflect the agreed structure.
Before a dispute arises, the investor should already know which court or arbitral tribunal will hear the dispute, where the counterparty’s assets are located, whether interim measures are available, and how a judgment or award can be enforced in Turkey.
Conclusion
Turkish international commercial law offers foreign investors both significant opportunities and important legal responsibilities. Turkey’s strategic location, manufacturing capacity, domestic market and investment framework make it attractive for international business. However, successful investment requires more than commercial ambition. It requires legal planning.
Foreign investors should structure their Turkish operations with carefully drafted corporate documents, strong commercial contracts, effective payment security, customs compliance, clear dispute resolution clauses and enforceable exit mechanisms. They should also understand the interaction between Turkish law, foreign law, international conventions, arbitration rules and mandatory local regulations.
In practice, the most successful foreign investors in Turkey are those who treat legal risk management as part of the investment itself. A well-structured investment can prevent disputes, strengthen negotiation power, protect capital, facilitate growth and improve enforceability if conflict becomes unavoidable.
