1. Why applications fail
The most common reasons an apostille application is refused, and what each means.
2. The document is not apostillable
The document is not a public document within the Convention’s meaning, and it has not been notarized.
A commercial invoice, a packing list, a sales contract drafted by the parties: none of these is a public document in its own right. Notarization is what creates an apostillable document.
The exception is a document already issued by a government authority, such as a business licence. Those may be apostillable directly, though practice varies by locality.
The failure: submitting a raw commercial document and expecting an apostille.
3. The notarial certificate is defective
The notary’s certificate is not in a form the issuing authority will accept.
Common causes: the notary office does not normally handle foreign-related work; the certificate omits information the issuing authority requires; the certification is of a type that does not constitute a notarial act for Convention purposes.
The failure: using a notary who is convenient rather than one who handles foreign-related work.
4. The signature cannot be verified
The apostille certifies a signature or seal. Where the issuing authority cannot verify the notary’s signature against its records, the application fails.
This happens where the notary is newly appointed, or where the notary’s specimen has not been registered with the foreign affairs office.
The failure: timing. A notary appointed recently may not yet be in the verification system.
5. The document is incomplete
Pages missing, an unsigned page, a certificate without its annex.
Where the document is a multipage instrument, all pages must be present and the notary must certify the whole.
The failure: submitting a document that does not match what the notary certified.
6. The document is in a language the office cannot process
This is less common at the issuing stage, since the apostille concerns the notarial certificate rather than the content.
But where the document or the notarial certificate is in a language the office cannot verify, processing may be suspended.
The failure: a document prepared in an unusual language without translation.
7. The destination is not a Convention party
An apostille is issued for a document destined for a country that is not a party, or that has filed an objection.
The apostille is technically issued, and the destination does not accept it.
The failure: not checking the destination’s status. This is the mistake with the most expensive consequences, because the document is prepared, apostilled, shipped, and refused.
8. The document is outside the Convention’s scope
Certain documents are excluded from the Convention regardless of the destination.
Documents executed by diplomatic or consular agents.
Documents relating to commercial or customs operations, in some readings.
The failure: assuming that any document can be apostilled if the destination is a party.
9. The receiving authority requires something else
The apostille is issued correctly. The receiving authority refuses the document because it wanted consular legalization, or registration, or a different form of certification.
The failure: not asking the receiving authority what it accepts.
10. Prevention
Four checks before applying.
Is the document a public document or notarized by a foreign-related notary?
Is the destination a Convention party, and does it apply to China?
Does the receiving authority accept an apostilled document for this purpose?
Is the notarial certificate in the form the issuing office accepts?
All four are answerable in under an hour and prevent the majority of refusals.
11. Closing view
Apostille refusals are rarely about the apostille. They are about the underlying document, or about not checking the destination.
The checks are cheap. The failures are not.
