Your Marriage Celebrant will charge you a booking fee "which is usually a non-refundable" when you meet with him/her to complete the Notice of Intended Marriage (NOIM).
The booking fee covers the costs for the Celebrants time in meeting with the couple, completing the Notice of Intended Marriage Form, any other legal vested obligations and for making a number of his/her relevant resources available to you. Payment of this fee also secures your chosen date and time for your wedding.
Each Marriage Celebrant has different terms and conditions in regard to their fees and refund policy. These aspects should be outlined clearly in his/her Statement of Fees provided to you and you should be made aware of all possible costs at the outset of the engagement.
