A civil union may be contracted under the act by a same-sex or opposite-sex couple, and they may choose to form it either as a marriage or as a
civil partnership. Whichever name is chosen, the legal consequences of a civil union are the same as those of a marriage under the
Marriage Act. Any reference to marriage in any law is deemed to include a civil union, and any reference to a husband, wife or spouse is deemed to include a spouse or partner in a civil union. A person may not contract a marriage or civil partnership if he or she is already married (or civilly partnered) under the Civil Union Act, the Marriage Act, or the Recognition of Customary Marriages Act. Both partners must be 18 or older and mentally competent. The same prohibited degrees of
consanguinuity and
affinity apply as would apply under the Marriage Act. A marriage or civil partnership must be solemnized by a marriage officer in the presence of the partners and two witnesses. The solemnization may occur in a public office, a private house, or in premises used for the purpose by the marriage officer. The marriage officer asks each partner: and when each partner has said "yes", the marriage officer solemnizes the marriage by saying: Secular marriage officers under the Marriage Act
magistrates and
Home Affairs officialsare automatically marriage officers for the purposes of the Civil Union Act. Marriage officers who are ministers of religion are not marriage officers for the purposes of the Civil Union Act unless both they and their denomination apply to be designated as such. Unlike the Marriage Act, the Civil Union Act does not place any restriction on the religious denominations of legally designated marriage officers. Marriage officers have the same powers, responsibilities and duties under the Civil Union Act as they do under the Marriage Act. ==Amendment==
