Pre-marital relation of a spouse, resulting in the wife being pregnant at the time of the marriage by…

Section 12(1)(d) of the Hindu Marriage Act, 1955 makes a marriage voidable, and so annullable by a decree of nullity, where "the respondent was at the time of the marriage pregnant by some person other than the petitioner". The petition must be filed within one year of the marriage, the petitioner must have been ignorant of the facts, and there must have been no intercourse with consent after discovering them.

Adultery is a ground for divorce and judicial separation only when it takes place after the marriage, so pre-marital conduct does not fall under those remedies.
