What’s the difference between an annulment and a divorce in Singapore?

Short answer

A divorce ends a marriage that was legally valid, while an annulment declares that the marriage was never valid at all, or should be treated as invalid due to a specific defect, restoring your legal status to single rather than divorced. Annulment is only available on narrow, specific grounds set out in the Women's Charter, so most couples seeking to end their marriage will still need to go through divorce instead.
