Under Section 16(2) of the Hindu Marriage Act, 1955, legitimacy in voidable marriage applies to:

Section 16(2) of the Hindu Marriage Act deems legitimate any child "begotten or conceived before the decree is made" annulling a voidable marriage under s.12, if the child would have been legitimate had the marriage been dissolved instead. Conception before the decree is the test, and the provision does not deal with adopted children or children of a former marriage.
