Divorce vs Annulment in South Africa
Divorce and annulment both bring a marriage to an end, but they are legally very different. Divorce dissolves a valid marriage that has broken down; annulment treats a defective marriage as if it was never valid in the first place.
Divorce
The legal dissolution of a valid marriage that has irretrievably broken down (or, rarely, on the grounds of mental illness or continuous unconsciousness).
When it applies: The marriage was validly entered into but has since broken down beyond repair.
Law: Divorce Act 70 of 1979
Example: A couple married for eight years grows apart; one spouse sues for divorce on the ground of irretrievable breakdown.
Annulment (Nullity)
A court declaration that a marriage was void or voidable because of a defect that existed at the time of the wedding — treating it as if it was never valid.
When it applies: A defect existed at the start: e.g. one party was already married (bigamy) or the parties are within a prohibited degree; or (voidable) there was duress, fraud, non-disclosure, or incapacity.
Law: Common law; Marriage Act 25 of 1961 (validity requirements)
Example: A person discovers their spouse was already legally married to someone else — the second marriage is void and can be annulled.

Frequently Asked Questions
Can I get an annulment just because the marriage was very short?
No. A short marriage is not a ground for annulment — that would be a divorce. Annulment requires a defect that existed at the wedding, such as bigamy, fraud, duress, or a prohibited-degree relationship.
Is a marriage automatically annulled if my spouse was already married?
A bigamous marriage is void from the outset, so it has no legal effect. But you should still obtain a declaratory court order confirming the nullity, to avoid any confusion about your legal status.
Are children from an annulled marriage illegitimate?
No. South African law protects children regardless of their parents' marital status — children of a void or annulled marriage remain legitimate and are entitled to maintenance and inheritance.
