- Two copies of the Official Certificate of Marriage
- The Presentation Certificate (that's the pretty one. printed in colour on creamy/yellow paper, with the Commonwealth Coat of Arms on the top of it)
The celebrant keeps one copy of the Official Certificate and forwards the other to Births, Deaths, and Marriages so that your marriage can be registered. All celebrants and all clergy persons who are licensed to solemnise marriages have a Statutory Obligation to send off your marriage papers (Notice of Intended Marriage and Official Certificate) within 14 days to Births Deaths and Marriages in the state or territory in which your wedding took place. It's in the Marriage Act!
The celebrant will give you the Presentation
Certificate to keep.
You should sign using the same signatures you used on
the Notice of Intended Marriage.
In other words, your "usual" signature.
Oh, and all signatures should be in black ink.
