Civil Union vs Civil Marriage
In South Africa, a civil marriage under the Marriage Act and a civil union under the Civil Union Act have equal legal standing. The key historical difference was access — the Civil Union Act opened marriage to same-sex couples in 2006.
Civil Marriage
A marriage solemnised under the Marriage Act 25 of 1961 by a marriage officer (magistrate, Home Affairs officer, or designated religious officer).
When it applies: Available to opposite-sex couples. The Marriage Act has traditionally been the "default" marriage statute.
Law: Marriage Act 25 of 1961.
Example: A man and a woman marry before a magistrate under the Marriage Act.
Civil Union
A marriage or civil partnership solemnised under the Civil Union Act 17 of 2006, originally enacted to allow same-sex couples to marry.
When it applies: Available to both same-sex and opposite-sex couples. The Civil Union Act was amended in 2022 to remove restrictions that had allowed marriage officers to opt out of officiating same-sex unions.
Law: Civil Union Act 17 of 2006 (as amended by Act 4 of 2022).
Example: Two women marry under the Civil Union Act.

Frequently Asked Questions
Are civil unions "lesser" marriages in South Africa?
No. The Constitutional Court confirmed in Minister of Home Affairs v Fourie (2005) that same-sex couples have the same constitutional right to marriage as opposite-sex couples. Civil unions enjoy full legal parity with civil marriages.
What happens if I married under the Civil Union Act — do I need a different divorce process?
No. Divorce is governed by the Divorce Act 70 of 1979 for both civil marriages and civil unions. The process is the same.
Can I convert my civil union to a civil marriage or vice versa?
There is no formal conversion mechanism. If you wish, you would need to divorce and re-marry under the preferred statute. Practically, there is no legal reason to do this as both statutes have the same effect.
