Authentication, not approval
An apostille says the signature is genuine, not that the document is correct or sufficient. The receiving authority still decides whether the document meets its rules.
The apostille is usually attached to the original or a certified copy. Some offices accept electronic apostilles; others require paper. Confirm the format before ordering.
Frequently asked questions
Does every country accept apostilles?
No. Countries outside the Convention may require legalisation by their consulate, which is a different and often longer process.
Can one apostille cover several documents?
Usually each document needs its own, though practice varies. Ask the issuing office.
