Dear Rohini, Marriage can be nullified only on three grounds : (i) either party has a living spouse at the time of marriage; (ii) the parties are within the degrees of prohibited relationship and the custom or usage governing each of them does not permit the marriage between the two; (iii) parties are sapindas of each other and the custom and usage governing them does not permit their marriage. Your case does not fall within the above. Hence, your marriage cannot be declared as null and void. However, your marriage may be annulled by a decree of nullity on the ground that your consent has been obtained by fraud as to the material fact or circumstances governing the respondent. Section 12(1)(c) of Hindu Marriage Act applies to your case. You will have to file the petition before completion of one year from the date you came to know about being subjected to fraud. Else, you will not get the decree under section 12 of Hindu Marriage Act and you will have to go for divorce under section 13. Please file the petition immediately.
