# What does a Hague Apostille authenticate? > What does a Hague Apostille authenticate? The origin of a public document for use abroad, not its content. See what it certifies and who issues it. https://roxotranslations.com/2026/10/03/what-does-a-hague-apostille-authenticate/ What does a Hague Apostille authenticate? The origin of a public document: the signature, the capacity of the person who signed it and the seal, so the document is valid in another country that signed the Hague Convention. A Brazilian diploma that needs to be valid in the United States, or an American birth certificate that needs to be valid in Brazil: in both cases, the original document usually is not enough on its own. Understanding what it really certifies avoids two common mix-ups: thinking it replaces the translation, or thinking any document can receive one. See the Apostille Service ## Key takeaways - The Apostille is a certificate issued by an authority in the country of origin that confirms the authenticity of the signature, the capacity of the person who signed and the seal on the document. - It is only valid between countries that signed the 1961 Hague Convention, and both Brazil and the United States are members. - The Apostille does not certify the content of the document, only its origin: it is not a guarantee that the information in it is true. - It is different from a certified translation: one authenticates where the document came from, the other guarantees that the translated text is faithful. Often both are needed together. - Not every document can be apostilled directly: some must first go through a notary or the issuing agency. ## Contents - What a Hague Apostille authenticates - Who can use the Apostille: member countries - Apostille vs. certified translation: not the same thing - What the Apostille does not do - Who issues the Apostille - Frequently asked questions ## What a Hague Apostille authenticates A Hague Apostille is a certificate attached to a public document that confirms three specific things: the authenticity of the signature of the person who signed the document, the capacity in which that person acted (the position they hold), and the identity of the seal or stamp on the document. It does not assess whether the content of the document is true: it only confirms that the document came from who it says it came from. ## Who can use the Apostille: member countries The Apostille only has effect between countries that signed the 1961 Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents. Brazil joined the Convention in 2016, and the United States has been a member since 1981. Between these two countries, the Apostille replaces a longer and more bureaucratic consular legalization process. ## Apostille vs. certified translation: not the same thing The Apostille authenticates the origin of the document in its original language. A certified translation guarantees that the translated version is faithful to the original text. They are complementary processes, not substitutes: a Brazilian document for use in the US often needs both, the Apostille on the original document (or on a certified copy of it) and then a certified translation into English. ## What the Apostille does not do The Apostille does not verify whether the information in the document is true, does not correct errors in the original document, and does not replace other specific requirements of whoever will receive the document, such as additional notarization or translation. It specifically solves the question of the formal authenticity of the document between the two countries. ## Who issues the Apostille Each member country designates its own competent authorities to issue the Apostille. In Brazil, these are the notary offices (cartórios) authorized by the CNJ; in the United States, usually the Secretary of State of each state, or the federal Department of State for federal documents. The right authority depends on where the document was originally issued. QuestionAnswer What does the Apostille certify?The authenticity of the signature, capacity and seal on the document, not its content Between which countries is it valid?Only between members of the 1961 Hague Convention (Brazil and the US included) Does it replace the translation?No: they are complementary processes, often used together Who issues it?The authority designated by the country where the document was issued (it varies by country and, in the US, by state) ## Frequently asked questions ### Does a Hague Apostille certify that the information in the document is true? No. It only certifies the authenticity of the signature, the signer's capacity and the document's seal, and it does not verify whether the content itself is true. ### Does the Apostille replace a certified translation? No, they are complementary processes. The Apostille authenticates the document's origin; the certified translation ensures the fidelity of the translated text. Both are often required together. ### Can any document receive an Apostille? Not necessarily. The document generally needs to be a public document, and some need to go through a specific notary or issuing agency before being apostilled. ## Does your document need an apostille?
