Australia's one calendar month notice rule for marriage, explained with real dates. What starts the clock, what does not, and when shortening of time applies.
Australian marriage law usually requires one calendar month’s notice before the marriage.
That means your NOIM must usually be given to your celebrant at least one calendar month before the date you want to marry.
The simplest way to think about it
If the NOIM is given on:
- 5 May, the earliest ordinary marriage date is 5 June
- 18 August, the earliest ordinary marriage date is 18 September
It is a calendar month, not four weeks.
What does not start the notice period
These things do not start the legal clock:
- sending an enquiry
- paying the fee
- filling out the booking form
- choosing a preferred date
The notice period starts when the NOIM has actually been given to the celebrant.
Can the notice period be shortened?
Sometimes, but only in limited circumstances and only if a prescribed authority approves a shortening of time.
The categories include:
- employment or travel commitments
- wedding or celebration arrangements
- medical reasons
- legal proceedings
- error in giving notice
