Tell your celebrant as soon as your plans change, and confirm the revised arrangements in writing. Check their availability, your venue and the terms of your booking.

If you reschedule, your celebrant will check that the new date meets the NOIM timing requirements. A marriage must normally take place between one and 18 months after the notice was received. Moving beyond that window means further paperwork and a new notice period may be needed.

Lodging a NOIM does not oblige you to marry. Cancellation charges, transferred booking fees and refunds depend on your agreement and applicable consumer law. If changing celebrants, ask about a proper transfer of the notice and documents.
