What does an apostille certify?
An apostille is a standard certificate under the Hague Convention of 5 October 1961. It authenticates the signature on a public document, the capacity in which the signer acted and, where appropriate, the identity of the seal or stamp. It does not certify the content of the document and does not confirm that the facts stated in it are correct.
The certificate is normally placed on the document itself or on an allonge permanently attached to it. Its French heading — ‘Apostille (Convention de La Haye du 5 octobre 1961)’ — is mandatory regardless of the language used for the remaining fields. Depending on the competent authority, the certificate and its register may be paper-based or electronic.
When does the Apostille Convention apply?
The system applies when a public document is issued in one Contracting Party and is to be used in another Contracting Party for which the Convention is in force. If either the state of origin or the destination state is outside the Convention, a different legalisation route through national authorities and diplomatic or consular missions may apply.
An apostille is not required in every cross-border case. European rules, bilateral agreements, national law or the receiving authority’s own practice may exempt particular documents from legalisation. The final requirement therefore depends on the countries involved, the type and purpose of the document and the institution that will receive it.
Private documents do not automatically fall within the Convention simply because they will be used abroad. When a signature on a private instrument is notarised, the notarial certification may become the public act to which an apostille can be attached.
How is an apostille identified and verified?
The standard model contains ten numbered fields covering the country, the signer, the signer’s capacity, the seal or stamp, the place and date of issue, the competent authority, the certificate number, the seal and the signature. This common structure makes the certificate recognisable even when the entries are completed in another language.
Bulgarian competent authorities maintain registers of the certificates they issue. A search by number, date and authority can confirm whether an apostille appears in the relevant register, but it does not replace the receiving institution’s assessment of the underlying document. Electronic verification belongs in the register of the authority that issued the certificate.
Who issues apostilles in Bulgaria?
Competence is divided among four groups of authorities according to the origin of the document. The distinction is decisive because one authority cannot apostille an act assigned by law to another.
Ministry of Justice. The Ministry authenticates acts issued by courts and notaries. This group includes judgments, certificates and other judicial acts, as well as notarial certifications when the document satisfies the conditions for an apostille. Issued certificates can be checked in the official Ministry of Justice register.
National Centre for Information and Documentation (NACID). NACID issues apostilles for educational and certification documents originating from higher education institutions, institutions in the preschool, school and vocational education systems, the Ministry of Education and Science and its units. The scope may include diplomas, supplements, academic transcripts and other documents issued by a competent educational institution. Current service information and verification are available from NACID and the apostille register.
Regional administrations. They issue apostilles for documents drawn up by mayors and municipal administrations. Civil-status certificates and other municipal administrative acts are common examples, although competence is determined by the issuer and the legal nature of the particular document.
Ministry of Foreign Affairs. The Ministry authenticates the remaining administrative acts that do not belong to the Ministry of Justice, NACID or the regional administrations, once the required prior certifications are present. This may cover documents from central administrations and other public bodies. Official guidance and electronic verification are provided by the Ministry of Foreign Affairs and its apostille register.
Apostille, translation and certification of the translation
An apostille and a translation perform different functions. The apostille authenticates the origin of the public document, while the translation conveys its content in the language required by the receiving institution. Adding an apostille does not automatically create a translated or certified translation.
The order of the steps depends on the document and the destination country. In one case the original is apostilled first and both document and certificate are then translated; in another, a certified translator’s signature or a particular format may also be required. The receiving authority decides whether it accepts an original, a certified copy, a paper document or an electronic document.
La Fit Trans arranges professional translation and the related certifications for documents intended for use abroad. The service is aligned with the type of document, its country of issue, the destination country and the formal requirements stated by the recipient.
Validity and currency of the document
The Hague Convention itself does not set a general expiry date for an apostille. This does not mean that every underlying document remains acceptable indefinitely. The document may have its own period of validity, and the receiving institution may require a recently issued or recently apostilled copy.
Changes to the competent authority, the specimen signature or the electronic register may also affect verification. Current conditions are established by the official issuer of the document and the institution before which it will be presented.
Practical scope of the service
Preparing a document for international use may involve identifying the issuer, checking prior certifications, identifying the competent apostille authority, translating the document and the apostille, and formatting the file according to the recipient’s rules. These elements form a connected service, but each retains its separate legal function.
The correct procedure cannot be determined from the document’s title alone. Two certificates with similar content may follow different routes when issued by different bodies or intended for different countries. Reliable preparation therefore starts with the origin and intended use of the specific document.
