A3. ‘Apostille‘ is French for a ‘footnote‘. France co-sponsored the Hague Apostille Convention (see Q2 above), thus its terminology was adopted.
An Apostille is affixed by the relevant authority in a country which has acceded to that convention, either by a rubber stamp, verified by an authorised person and sealed with an official seal, or by attaching a separate certificate.
An Apostille certifies that the notary or government authority which issued the document is indeed authorised to do so. It does not bear any relation to the content of the document, and does not of itself confer any validity on it.
Similarly, an authentication will be affixed by DFAT for non-Hague Convention countries.
