Under the Hindu Marriage Act, 1955, a petition on the ground of force or fraud must be filed:

Under section 12(2)(a)(i) no petition on the ground of force or fraud is entertained if "the petition is presented more than one year after the force had ceased to operate or, as the case may be, the fraud had been discovered". The one-year limit counted from the date of marriage applies to the pregnancy ground under section 12(2)(b).
