As from 1 August 1991, the marriageable age is 18 years. If a person, not yet 18, wishes to marry prior to his or her 18th birthday, only a court empowered to give a 'Section 12' order can give authority for this marriage to be solemnised.

A Notice of Intended Marriage may be lodged prior to the 18th birthday, as long as the marriage occurs after the birthday.
