Quick question
What are the legal grounds for annulment of marriage in Singapore?
Short answer
A marriage can be annulled if it's void, for example due to bigamy, underage marriage, prohibited relationships (for eg.marriage between siblings), improper solemnisation, or if it's voidable, such as through non-consummation, lack of valid consent, or a spouse's undisclosed pregnancy by another person at the time of marriage.
