Apostille and Notarial Certification — International Document Authentication Process

In the globalizing world, the need for individuals and institutions to conduct legal transactions internationally increases every day. For an official document issued in one country to be accepted as valid in another country, certain authentication procedures must be fulfilled. The primary procedures include apostille and consular legalization. The 1961 Hague Apostille Convention has significantly simplified the international document authentication process and eliminated the requirement for diplomatic/consular legalization. In this article, we will comprehensively examine the concept of apostille, the 1961 Hague Convention, consular legalization, apostille-issuing authorities in Turkey, procedures, fees, and practical issues.

What Is an Apostille and Why Is It Necessary?

An Apostille is an international authentication annotation that enables an official document issued in one country to be accepted as valid in another country without any additional authentication procedure. An apostille consists of a standard form containing specific information, placed on the document or on a separate paper attached to the document.

The fundamental purpose of the apostille system is to facilitate international document circulation. In the pre-apostille era, a long and complex chain of authentication was required for an official document issued in one country to be used in another: first, the superior authority of the issuing authority, then the Ministry of Foreign Affairs, and finally the consulate of the country where the document would be used had to certify it. The apostille has reduced this multi-stage process to a single transaction.

An apostille does not confirm the accuracy of the document's content; it only confirms the authenticity of the signature, seal, or stamp on the document and that the person who signed the document was authorized to do so. In other words, the apostille is a confirmation regarding the formal validity of the document, and no content verification is performed.

The 1961 Hague Apostille Convention

The Convention Abolishing the Requirement of Legalization for Foreign Public Documents (Convention de La Haye du 5 octobre 1961), commonly known as the Hague Apostille Convention, was signed in The Hague on 5 October 1961. The Convention entered into force on 24 January 1965. Turkey acceded to this convention on 8 May 1962, and the convention entered into force for Turkey on 29 September 1985.

The Convention applies to public documents issued in one contracting state and to be presented in another contracting state. The documents covered by the Convention are:

1. Documents issued by an authority or official connected with the courts or tribunals of the state, including documents issued by prosecutors, court clerks, and judicial officers.

2. Administrative documents (civil status records, diplomas, military documents, etc.).

3. Notarial documents.

4. Official certifications placed on documents signed by persons in their private capacity (registration records, declarations of existence at a certain date, signature authentications, etc.).

Documents not covered by the Convention are documents issued by diplomatic or consular agents and administrative documents directly related to commercial or customs operations.

Difference Between Apostille and Consular Legalization

Apostille and consular legalization are both authentication methods that enable a document issued in one country to be used in another. However, there are significant differences between them.

Between countries party to the Hague Convention, an apostille is sufficient, and consular legalization is not required separately. However, if the country where the document will be used is not a party to the Hague Convention, the apostille is invalid, and consular legalization must be obtained.

The consular legalization process is much longer and more costly than the apostille. The document is first authenticated by a notary, then certified by the governor's office or district governor's office in the province where the notary's office is located, then approved by the Ministry of Foreign Affairs, and finally certified by the consulate of the country where the document will be used located in Turkey.

Apostille-Issuing Authorities in Turkey

The authorities authorized to affix the apostille annotation in Turkey vary according to the type of document:

Governor's Offices and District Governor's Offices: For documents issued or authenticated by notaries and administrative documents (civil status records, diploma certifications, etc.), the provincial/district secretariat offices within the governor's or district governor's offices are authorized to affix the apostille annotation. In practice, the most common apostille-issuing authority is the provincial secretariat offices of governor's offices.

Competent Authority for Court Decisions: For court decisions and documents issued by authorities connected with judicial organs, the governor's office at the location of the chief judge of the heavy penal court is competent.

To obtain an apostille annotation, an application is made to the competent authority with the original document or its notarially certified copy. Presentation of an identity document is required with the application. The process is generally completed on the same day or within a few business days.

Required Documents and Process for Apostille

The process to be followed for an apostille may vary depending on the type of document. Generally, the process is as follows:

1. Document Preparation: The original or notarially certified copy of the document to be apostilled is prepared. If the document was issued by a notary, the notary's original document or certified copy is sufficient.

2. Translation (If Necessary): If the document needs to be presented in a foreign language, it must be translated by a sworn interpreter and authenticated by a notary. Notarially certified translations in Turkey are carried out under Article 103 of the Notary Law.

3. Apostille Application: An application is made to the competent authority (generally the governor's office) with the prepared document. The applicant's identity document is presented.

4. Affixing the Apostille Annotation: After verifying the authenticity of the document, the competent authority places the standard apostille annotation on the document or on a separate page attached to the document.

5. Document Ready for Use: After the apostille annotation is affixed, the document can be used in any country party to the Hague Convention without additional authentication.

Content and Standard Form of the Apostille Annotation

Article 4 of the Hague Convention determines the standard form of the apostille annotation. The apostille annotation is square or rectangular and must be at least 9 x 9 cm. The following information is included in the annotation:

1. Name of the country where the document was issued

2. Name of the person who signed the document

3. Title of the person who signed the document

4. Authority to which the seal/stamp on the document belongs

5. Place where the apostille was issued

6. Date the apostille was issued

7. Authority issuing the apostille

8. Apostille number

9. Seal/stamp of the authority issuing the apostille

10. Signature of the official issuing the apostille

The apostille annotation begins with a French title: "Apostille (Convention de La Haye du 5 octobre 1961)". The remainder of the annotation is prepared in the official language of the country issuing the apostille.

Which Documents Require an Apostille?

The documents most frequently apostilled in practice are:

Civil Status Documents: Documents relating to personal status such as birth certificates, marriage certificates, divorce decrees, death certificates, and civil registry records.

Educational Documents: Education-related documents such as diplomas, transcripts, student certificates, and equivalency certificates.

Judicial Documents: Criminal records, court decisions, and prosecution documents.

Commercial Documents: Trade registry gazette, signature circulars, company articles of association, and activity certificates.

Notarial Documents: Documents issued or authenticated by notaries such as powers of attorney, consent forms, undertakings, and declarations.

Official Correspondence: Official letters issued by ministries, institutions, and public organizations.

Apostille Fees

Fees charged for apostille transactions vary according to the type of document and the competent authority. As of 2026, the apostille fee in Turkey is determined according to the tariff attached to the Fees Law No. 492, and a fixed fee is charged [TO BE VERIFIED].

In addition to the apostille fee, additional costs such as notary fees and sworn interpreter fees may arise if a notarially certified copy or translation of the document is required. All these items should be taken into account when calculating the total cost.

Some documents may be exempt from fees. Fee exemptions may apply to documents within the scope of legal aid, documents exempt under international agreements, and documents issued by certain public institutions.

Common Issues in Apostille Practice

Some issues are frequently encountered in apostille practice:

Translation Issues: The apostille annotation confirms only the formal validity of the document, not its content. Therefore, the document may need to be separately translated in the country where it will be used. Some countries accept only translations made by their own sworn interpreters.

Expired Documents: Some countries require that the apostilled document be used within a certain period. For example, criminal records must be used within 3-6 months in some countries. Therefore, the timing of the apostille process is important.

Double Apostille Issue: There are different practices among countries regarding whether separate apostilles need to be placed on both the original document and its translation. The general practice in Turkey is to apostille the notarially certified translation as a separate document.

Electronic Apostille (e-Apostille): The Hague Conference on Private International Law is promoting the electronic apostille application. Some countries have transitioned to e-apostille applications, and efforts are ongoing in Turkey in this direction.

Consular Legalization Process (Countries Where Apostille Does Not Apply)

Consular legalization is mandatory for documents to be used in countries that are not party to the Hague Convention. The consular legalization process consists of the following stages:

1. Authentication of the document by a notary

2. Certification of the notary's signature by the governor's office of the province where the notary is located

3. Approval of the governor's office certification by the Ministry of Foreign Affairs

4. Certification of the Ministry of Foreign Affairs approval by the embassy or consulate in Turkey of the country where the document will be used

This process can take much longer than the apostille (1-4 weeks), and separate fees and charges must be paid at each stage. Additionally, each authority's working hours, appointment systems, and document requirements may vary.

Apostille on Documents Coming from Abroad to Turkey

Documents issued in foreign countries and to be used in Turkey must also bear an apostille annotation. Documents issued in a country party to the Hague Convention and apostilled by the competent authority of that country are accepted in Turkey without being subject to additional authentication procedures.

For apostilled documents coming from abroad to be usable in Turkey, they must be translated into Turkish by a sworn interpreter and this translation must be authenticated by a notary. The apostille does not cover the translation of the document's content; it only confirms its formal validity.

For documents coming from countries not party to the Hague Convention, certification by the Turkish consulate in that country and then approval by the Ministry of Foreign Affairs in Turkey is required.

Relationship Between Apostille and Notarial Practice

There is a close relationship between notarial transactions and apostille. Documents issued or authenticated by notaries are among the most frequently processed document types within the scope of apostille. Notarial documents such as powers of attorney, consent forms, declarations, and translation authentications require an apostille annotation if they are to be used abroad.

To have an apostille placed on a document issued by a notary in Turkey, it is sufficient to submit the document to the provincial secretariat office of the governor's office in the province where the notary is located. The governor's office verifies the notary's signature and seal and affixes the apostille annotation.

Notaries play an important role in the apostille process. For documents prepared by private individuals to be usable abroad, they must first be authenticated by a notary and then apostilled. Notaries also play a role in authenticating translations of apostilled documents coming from abroad.
