An Apostille Certificate & International Document Legalisation Service


Most Australian public/government or notarised private/documents to be recognised and accepted by overseas businesses, governments or Courts... must be authenticated or "legalised"… that is, formally proved valid and genuine.

An Apostille Certificate is a short and simple form of legalisation, but available only to those countries which are signatories to The Hague Convention.

If not a signatory to The Hague Convention, full document legalisation by the foreign country's Embassy or Consulate in Australia is required in place of an Apostille Certificate.
