A decree of nullity is a judicial decree determining in effect that the marriage in question never existed. It is different from a divorce which acknowledges that there was a marriage and it is ending. The decree of nullity declares that the marriage is and has always been null and void as there are many conditions under which marriage in India can be considered as an invalid marriage. A party has to present a petition before Court against the other party, setting in detail the reason for the annulment.
