1. Company Registration, Licensing & Trade Registry Obligations

E-commerce companies must first register as a legal entity—usually as an LLC or joint-stock company—with the Turkish Trade Registry and relevant chambers of commerce. Istanbul Law Firm manages incorporation, articles drafting, and registration balancing with foreign ownership structures. Our Turkish Lawyers assist with open banking requirements, commercial registry filings, and online activity permits. The English speaking lawyer in Turkey team ensures that all documents are correctly translated for international shareholders and foreign remittance filings. We also support applications for special trade licenses when dealing with regulated goods, such as pharmaceuticals or food products. Proper entity setup ensures your e-commerce operation is legally backed from the start.

Post-registration, e-commerce sites must publish mandatory information such as trade name, registration number, contact information, and platform operators. Istanbul Law Firm ensures this information appears on your website footer and user interface in compliance with Electronic Commerce Law. Our Turkish Lawyers verify website conformity with template notices, refund clauses, and cancellation policies. The English speaking lawyer in Turkey advisors prepare user-facing content in Turkish and English to match multilingual buyer markets. Additionally, we register verified seals or trust marks used in digital commerce infrastructure. Meeting these public disclosure norms builds trust with consumers and the authorities.

Finally, annual updates—board changes, capital adjustments—must be filed with the Trade Registry and published in the Trade Registry Gazette. Istanbul Law Firm monitors these filing deadlines and prepares required documentation. Our Turkish Lawyers ensure corporate records reflect any operational changes or foreign investment structure alterations. English speaking lawyer in Turkey staff generate bilingual compliance reminders and liaise with international advisors if needed. Timely filings prevent administrative penalties and aid future due diligence. A compliant registry presence is the foundation of transparent e-commerce operations.

2. Consumer Protection, Returns & Terms of Service

Under Turkish Consumer Protection Law, e-commerce operators must provide clear information on price, identity, product features, delivery terms, and cancellation rights before concluding contracts. Istanbul Law Firm drafts consumer-friendly Terms of Service, cookie policies, and return procedures compliant with law. Turkish Lawyers ensure that mandatory 14-day right of withdrawal clauses are included and correctly interpreted. English speaking lawyer in Turkey advisors localize these documents for international clientele. We also prepare bilingual pre-contractual information forms and maintain change logs. Full transparency in consumer law compliance builds buyer trust and mitigates legal risk.

E-commerce platforms are required to offer easy cancellation and refund processing with no penalties for remote purchases. Istanbul Law Firm sets up compliant refund protocols and draft templates for cancellation forms. Our Turkish Lawyers ensure systems process refunds within 14 days after request in accordance with the law, and we align with electronic declaration obligations under KEP and e-archives. English speaking lawyer in Turkey staff help foreign investors design multilingual refund journey communications. Platforms need to report refund processes and must include notifications in user interfaces. This mitigates consumer complaints and fosters regulatory alignment.

Furthermore, e-commerce operators must display complaint mechanisms, alternative dispute resolution (ADR) options, and links to Turkish Consumer Arbitration Committees. Istanbul Law Firm establishes complaint flowcharts, manages ADR registration, and supports arbitration applications. Our Turkish Lawyers draft dispute clauses to channel consumer disputes to online consumer arbitration rather than courts. English speaking lawyer in Turkey advisors finalize user journey documents in English, ensuring clarity for international clients. We also prepare periodic compliance reports on consumer grievances.

3. Data Protection & Privacy Compliance

E‑commerce companies operating in Turkey must fully comply with the Personal Data Protection Law (KVKK), which governs how customer data is collected, stored, processed, and deleted. Istanbul Law Firm conducts comprehensive KVKK compliance assessments, prepares data processing inventories, and drafts clear privacy policies tailored to e-commerce models. Our experienced Turkish Lawyers ensure that both Turkish and English language policies conform to the law, while the English speaking lawyer in Turkey team provides dual-language contracts and consent forms for international users.

Additionally, we help set up user consent modules integrated into mobile apps and websites, balancing UX and legal compliance. With a properly implemented data protection framework, e-commerce platforms not only mitigate legal risk, but also gain consumer trust and credibility in local and global markets.

When e-commerce platforms share personal data with third-party service providers, they must enter into compliant data transfer agreements that include confidentiality clauses and liability protections. Istanbul Law Firm provides standardized agreement templates and oversees the negotiation of terms to ensure legal alignment. Our Turkish Lawyers confirm that data transfers are made only to countries with adequate data protection rules, and we prepare annual compliance reports to the KVKK Board as required.
