Foreign Corporate Shareholder in Turkey: Fixing Apostille and Signing Authority Problems

A foreign company can own all or part of a Turkish limited liability company (LLC) or joint-stock company (JSC). In practice, the difficult part is rarely foreign ownership itself. Registration is delayed when the overseas company’s existence, corporate decision and signatory authority cannot be followed as one continuous evidence chain.

The solution is not to apostille every paper indiscriminately. First identify what each document must prove, who is legally able to issue or sign it, and whether Turkey will accept the authentication route used in the document’s country of origin. Then align the corporate resolution, power of attorney, registry extract and Turkish translations before originals are couriered.

Why foreign corporate shareholder files are rejected

The Turkish registry must answer several separate questions. A certificate of incorporation may prove that a company was formed, but not that it is still active. A recent registry extract may show the directors, but not necessarily that one director may act alone. A board resolution may approve the investment, but the person signing that resolution must also be authorised under the shareholder’s own law and corporate records.

Türkiye’s Investment Office expressly lists a certificate of activity containing current-status and signatory information, a resolution of the competent corporate organ and—when the application is handled by proxy—a notarised power of attorney. It also states that foreign-executed documents must be notarised and apostilled or alternatively ratified by the Turkish consulate, then officially translated and notarised in Turkey.

Apostille versus consular legalisation

An apostille does not confirm that the board made a commercially sensible decision or that the document’s statements are true. It authenticates the origin of a public document—principally the signature, capacity and seal or stamp. The HCCH Apostille Convention replaces the longer diplomatic or consular legalisation chain between states for which the Convention is in force.

United States: identify whether the document is state or federal

US formation certificates, certified articles, powers of attorney and many corporate records are normally state documents. The US Department of State directs applicants to the state that issued a state document for the relevant certification. Federal documents follow the federal authentication route. For a corporate shareholder, the correct Secretary of State or other state competent authority usually depends on the state of incorporation and on whose signature is being authenticated.

United Kingdom: legalisation through the FCDO route

The UK Legalisation Office checks whether signatures, stamps or seals match its records and attaches a paper apostille or, where acceptable, an e-Apostille. Do not assume that an electronic apostille will be accepted for a paper-based Turkish Trade Registry file; confirm the intended filing format before choosing it.

United Arab Emirates: plan the full attestation chain

For UAE-origin documents, map the competent local issuer, the UAE Ministry of Foreign Affairs attestation and the Turkish consular step applicable to the document. A free-zone or emirate-level company record may have a different issuer and verification route from a mainland company record. Start by confirming which authority can issue the current company extract and certify the signatory’s authority.

Who can sign for the foreign shareholder?

The answer comes from the foreign company’s own law, constitutional documents and current register—not from the Turkish company being formed. A person described as a director, manager, member or secretary may not automatically have unrestricted individual signing power.

1. Confirm the competent organ: Determine whether the board, shareholders, members, general partner or another body must approve formation of a Turkish subsidiary.

2. Confirm the signing rule: Establish whether one person may sign alone or whether joint signatures, a company seal or another formality is required.

3. Approve the transaction: The resolution should identify the investment with enough precision, including the Turkish vehicle, capital participation and any appointed representatives relevant to the file.

4. Delegate specific powers: If a local professional will act, the PoA should be granted by a person whose authority is proved by the current corporate evidence.

5. Keep names identical: Use the same legal name, registration number, registered office and signatory spelling across the resolution, PoA, translations and MERSİS entry.

What the corporate resolution should cover

There is no reliable universal one-paragraph resolution for every jurisdiction. The document must be valid under the shareholder’s own rules and sufficient for the Turkish transaction. Depending on the final structure, the resolution should address:

• approval to establish or participate in a Turkish LLC or JSC;

• the proposed company name, business purpose and registered city when these have been settled;

• the foreign shareholder’s capital commitment, ownership percentage and share class where relevant;

• appointment of the individual authorised to execute formation documents and grant a PoA;

• appointment of the Turkish company’s manager or board member, if that approval is being given in the same document;

• where the foreign legal entity itself will be a board member, the natural person designated to act on its behalf;

• authority to make necessary non-material amendments requested during registry review, if permitted and intended.

Keep the resolution consistent with the final MERSİS draft. A resolution that approves one company name, capital amount or ownership ratio while the application uses another creates an avoidable authority question.

Power of attorney: broad language is not always better

A formation PoA should be broad enough to complete the agreed workflow but specific enough for Turkish authorities to identify the delegated acts. Review whether it covers the steps actually assigned to the representative, such as:

• obtaining potential tax identification numbers;

• preparing, amending and signing MERSİS and Trade Registry submissions where legally permitted;

• signing or acknowledging the articles of association and ancillary declarations;

• submitting, collecting and correcting registry documents;

• making Competition Authority payments and completing related formalities;

• tax-office, Social Security or post-registration acts if these are within the engagement;

• bank-account opening only if the bank has separately approved the PoA wording and remote process.

Matching resolutions, powers of attorney and translations

The most expensive defects are cross-document mismatches. They often appear only after originals reach Turkey. Use one controlled data sheet for the shareholder and the proposed Turkish company, then compare every document against it.

Pre-filing document review checklist

Corporate identity and status

• Current official extract or certificate of activity shows the full legal name, jurisdiction, registration number, status and registered office.

• Signatory information is current and sufficient to establish individual or joint authority.

• Any name change, merger, conversion or continuation is supported by official evidence.

• The ultimate beneficial ownership information required for tax, registry and bank onboarding has been mapped.

Resolution and delegated authority

• The correct corporate organ approved the Turkish investment and satisfied quorum and voting rules.

• The resolution matches the final structure, capital, shareholding and management plan.

• The person signing the resolution and PoA is linked to current authority evidence.

• The PoA covers every delegated formation step but does not assume that registry authority automatically covers bank onboarding.

Authentication, translation and filing

• The apostille or consular legalisation route has been verified for the exact origin and document type.

• The competent authority will authenticate the signature or official certification actually used.

• All pages, attachments, seals and authentication endorsements remain physically or digitally linked.

• The Turkish translation reproduces names, registration numbers, dates, currencies and signing capacities consistently.

• Scans have been reviewed before originals are shipped, and the filing list has been confirmed with the competent Trade Registry for the chosen company type.

A safer execution sequence

1. Freeze the structure: agree the LLC/JSC choice, shareholder percentage, capital, managers or board, registered city and proposed activity.

2. Create the evidence map: assign one source document to each question of existence, authority, approval and delegation.

3. Draft locally for Turkish use: prepare the resolution and PoA against the planned MERSİS and registry steps, while checking validity under the foreign company’s own law.

4. Review unsigned drafts: reconcile names, registration data, capital and authority before notarisation.

5. Execute and authenticate abroad: use the proper signatories and the correct apostille or consular legalisation path.

6. Translate the completed package: translate the document together with every authentication endorsement, then complete Turkish notarial certification.

7. Run a final filing review: compare the original package with MERSİS, tax-number and Trade Registry data before the appointment.
