No, not all documents need to be notarised or certified before the apostille can be added. There are a lot of public documents that have the apostille issued without any additional notarisation or solicitor certification. When a document contains a recognised official signature, stamp or seal, further notarisation/certification is not required and should not be added.

Common documents that DO NOT need notarising/certifying include –

Birth Certificate
Marriage Certificate
Death certificates
Adoption Certificates
Certificate of No Impediment to Marriage
