Can a document be apostilled if it is written in a language other than English?
Yes.
A document may be apostilled even if it is written in a language other than English. In fact, some receiving countries require documents to be presented in their native language for acceptance.
The notarization process is generally handled the same way as any other document in the United States. The notary will verify the identity of the signer(s), witness the signature(s), and complete an English-language notarial certificate, such as a General Acknowledgment, which is attached to the document.
Once notarized, the document can be submitted for apostille through the Secretary of State in the state where the notary is commissioned. The apostille authenticates the notary's commission and signature—it does not certify, translate, or validate the contents of the document itself.
If a certified translation is required by the receiving country, that requirement should be confirmed before the apostille process begins.
