Under the marriage Act 1961 there are certain obligations that you, as a couple intending to get married, must meet prior to a marriage ceremony being solemnised:
A Notice of Intended Marriage (NIM) must be lodged with your Marriage Celebrant no less than one calendar month and no more than eighteen months prior to the marriage being solemnised.
Under normal circumstances the Notice of Intended Marriage would be completed at your first meeting with your chosen celebrant, or certainly before the marriage can be solemnised and within the above requirements. You are required to produce your original Birth Certificate, or authorised extract of such certificate.
Alternatively, you can produce either an Australian Passport or Overseas Passport as identification and evidence of date and place of birth. The passport can be expired but NOT cancelled.
In the case of persons who have been previously married a copy of the Divorce Certificate or Death Certificate, whichever is applicable, must be produced. Some overseas countries do not have a divorce system, rather they have an annulment process, the Philippines is one such country. There must be produced an order of annulment in regards to any dissolved marriage in such countries. Once again, it is important to remember that only original documents can be accepted.
