International document authentication: apostille, consular legalization, notarization and certified translation
To use a document (a diploma, a birth or marriage certificate, a power of attorney) officially abroad, it must be authenticated. Among parties to the 1961 Hague Convention this is an apostille: a single certificate that recognizes the signature and seal and replaces the multi-step consular legalization. For Uzbekistan the Hague Convention entered into force on 15 April 2012 (the instrument of accession was deposited on 25 July 2011); the USA has been a party since 1981 — so between Uzbekistan and the USA an apostille is sufficient, with no additional consular legalization required. Based on official sources.
An official document issued in one country is not automatically recognized in another — it must first be authenticated (legalized). Below, the difference between an apostille, consular legalization, notarization and certified translation is explained strictly on the basis of official sources — the Hague Conference on Private International Law (HCCH), the U.S. State Department and official Uzbek sources.
What an apostille is
An apostille is a certificate issued under the Hague Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents (the Apostille Convention). It authenticates the origin of a public document — the authenticity of the signature, the capacity of the signer, and the seal/stamp. With it, the document can be used in another Convention state without further legalization. The apostille is issued by a designated 'competent authority' in the country where the document originated.
Uzbekistan in the Hague Convention
Uzbekistan deposited its instrument of accession on 25 July 2011, and the Apostille Convention entered into force for Uzbekistan on 15 April 2012 — apostilles have been used from that date. In Uzbekistan the authority that issues the apostille depends on which body produced the document: civil-status (ZAGS) and notarial documents and justice documents — the regional departments of the Ministry of Justice system; court documents — the Supreme Court; prosecution, investigation and inquiry documents — the Prosecutor General's Office; education and science documents (diplomas, transcripts) — the State Testing Center under the Cabinet of Ministers; all other official documents — the Ministry of Foreign Affairs.
The USA is a party too — Uzbekistan–USA practice
The USA has been a party to the Hague Convention since 15 October 1981. So between Uzbekistan and the USA an apostille is sufficient: for a document moving between the two (both have been parties since 2012), no additional consular legalization is needed. To use a U.S. document in Uzbekistan, you obtain a U.S. apostille (state documents — the relevant Secretary of State; federal documents — the U.S. State Department's Authentications Office); to use an Uzbek document in the USA, you obtain an apostille from the relevant Uzbek authority above.
Consular legalization (for non-member countries)
If the destination country is not a party to the Apostille Convention, the older multi-step consular legalization applies: notary → that country's Ministry of Foreign Affairs → the embassy or consulate of the country where the document is going. Each step certifies the previous one. The apostille collapses this chain into a single certificate.
Notarization vs. apostille
A notary verifies identity, a signature or a copy and attests that a document was signed properly — a domestic act. An apostille authenticates the document (or the notary's authority) for international use among Hague members. Notarization alone is not recognized abroad; the apostille (or legalization) is the extra layer that makes it valid across borders. Often a notarized document becomes the 'public document' that is then apostilled.
Certified translation
Uzbek documents are issued in Uzbek (often Russian); to use them in the USA an English translation is usually required. In Uzbekistan the translation is made and then notarized and attached to the apostilled original. For the U.S. immigration service (USCIS), under 8 CFR § 103.2(b)(3), any foreign-language document must include a full English translation plus the translator's signed certification (that the translation is complete and accurate and that the translator is competent to translate); USCIS does not require a licensed translator or a notarized translation.
Documents commonly authenticated
Diplomas and academic transcripts; birth, marriage, divorce and death certificates; powers of attorney; police (no-criminal-record) certificates; notarial deeds and official copies. Note: an apostille authenticates only the origin of the document, not the truth of its contents, and does not override the receiving country's own rules (for example the validity period of a police certificate).
