For an overseas founder, the slow part of a Turkish company setup is often the document chain. Notary and apostille requirements for Turkish company setup depend on where a document was issued and who is signing it. The practical order is simple: identify the required corporate or identity document, authenticate it abroad where required, obtain an official Turkish translation, then take the final originals to the Trade Registry process.
Which foreign documents need notarisation and apostille?
Türkiye’s official investment guide says that, other than articles signed before authorised Trade Registry personnel, documents issued and executed outside Türkiye for the registration file must be notarised and apostilled, or alternatively ratified by the Turkish consulate in the country of transaction. The original executed, notarised and apostilled documents then need an official translation and Turkish notary certification.
The document list changes with the shareholder. The same official guide lists two passport copies for a foreign individual shareholder. A foreign corporate shareholder normally brings its registry and authority documents as well. Ask the relevant Trade Registry Directorate to confirm the current list for the chosen company type before commissioning translations.
What does an apostille actually confirm?
An apostille is a formal authentication certificate for a foreign public document. Under Article 5 of the HCCH Apostille Convention, it certifies the signature, the signer’s capacity and, where applicable, the seal or stamp. It does not certify that the underlying corporate resolution, passport copy or power of attorney is commercially correct.
Start by checking whether the issuing country and Türkiye are covered for the document in question. The HCCH status table is the primary reference for Convention status. Where the apostille route is unavailable, the Turkish government’s investment guide identifies Turkish-consulate ratification as the alternative route. Do not assume that a domestic notary stamp alone replaces either cross-border step.
Where does the Turkish notary fit after the foreign authentication?
The Turkish notary step is generally about the Turkish-facing file. The official guide states that originals executed, notarised and apostilled abroad must be officially translated and notarised by a Turkish notary. Keep the original, apostille or consular ratification, and the translation together. A clean scan is useful for advance review, but it is not a substitute for the originals requested at filing.
This is also why document sequencing matters. A translation made before the final foreign authentication can create a mismatch in names, dates, stamps or page order. Finalise the source document first, then authenticate it, then translate the finished document.
Is MERSİS the same as registration at the Trade Registry?
No. Invest in Türkiye describes MERSİS as the electronic system used for commercial-registry processes and says the memorandum and articles are submitted online there. The registration application and execution steps still run through the relevant Trade Registry Directorate. Treat MERSİS as the electronic filing layer, not as a replacement for the originals and formalities in a foreign-founder file.
For the final registry window, see our Turkish company-formation timeline guide. It explains why a same-day registry statement applies once the file is ready, rather than to the entire cross-border preparation period.
What should a foreign founder prepare before translating anything?
Use a short control sheet. Confirm the shareholder and director details exactly as they will appear in the articles. Confirm who will sign, whether a power of attorney is needed, and the issuing country for every document. Then ask for the registry-specific list, including the number of originals and copies.
- Match names, passport details and legal-entity names across every document.
- Authenticate the final version, not a draft that will later be amended.
- Keep every original, certificate and translation as one filing set.
- Check the Turkish translation against the apostille page and annexes before the appointment.
Can an apostille solve every Turkish company-formation issue?
No. It solves a narrow authentication question. It does not choose the company type, create a tax identity number, replace a director appointment, or answer sector-specific licensing requirements. It also does not cure an incomplete corporate resolution. The share-transfer process for a Turkish limited company illustrates the same broader point: corporate filings depend on the transaction and the legal record, not a single stamped document.
FAQ
Do all foreign founders need an apostille?
Foreign-issued registration documents normally follow the official authentication route described by Invest in Türkiye. Whether that is an apostille or consular ratification depends on the issuing-country route. Confirm the specific file with the Trade Registry Directorate.
Can a Turkish notary issue the apostille for a document created abroad?
No. The apostille is issued by the competent authority in the jurisdiction of origin. A Turkish notary handles the Turkish notarisation of the official translation described in the official investment guide.
Should translation happen before the apostille?
Usually finalise the source document and its foreign authentication first. Then translate the completed document, including relevant certificates and attachments, for the Turkish filing set.
Does MERSİS remove the need for originals?
No. MERSİS supports the electronic commercial-registry workflow. Foreign-founder files can still require formal originals and registry-facing execution steps.
