Happily Ever... Before and After

Although it's not mandatory to attend pre-marriage courses for a civil ceremony, it's worth noting that civil celebrants are required to provide couples they marry with a government information pamphlet called "Happily Ever... Before and After" and the details of pre-marriage education courses that are available, as well as urging you to consider enrolling in one. So, while you don't have to take a course, it's something to keep in mind if you're planning to tie the knot.
