An Apostille Certificate & International Document Legalisation Service
Australian public/government or notarised private documents that need to be recognised or accepted by overseas businesses, governments, courts or others must be verified, authenticated or “legalised”… that is, formally proved valid and genuine by the country of issue via official records.
An Apostille Certificate is a short and simple form of legalisation, but available only to those countries that 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.

Why an Apostille Certificate?
Prior to the introduction of Apostille Certificates, the burden fell on international governments, Courts and businesses to ascertain whether foreign public documents were authentic.
What does an Apostille look like?
An Apostille (Certificate) is a square approximately 9cm long, usually stamped onto the reverse side of a single page public document.
How effective is an Apostille certificate?
