Section 14 in The Hindu Marriage Act, 1955
14 No petition for divorce to be presented within one year of marriage .
(1) Notwithstanding anything contained in this Act, it shall not be competent for any court to entertain any petition for dissolution of a marriage by a decree of divorce, 28 [unless at the date of the presentation of the petition one year has elapsed] since the date of the marriage: Provided that the court may, upon application made to it in accordance with such rules as may be made by the High Court in that behalf, allow a petition to be presented 29 [before one year has elapsed] since the date of the marriage on the ground that the case is one of exceptional hardship to the petitioner or of exceptional depravity on the part of the respondent, but if it appears to the court at the hearing of the petition that the petitioner obtained leave to present the petition by any misrepresentation or concealment of the nature of the case, the court may, if it pronounces a decree, do so subject to the condition that the decree shall not have effect until after the 30 [expiry of one year] from the date of the marriage or may dismiss the petition without prejudice to any petition which may be brought after the 31 [expiration of the said one year] upon the same or substantially the same facts as those alleged in support of the petition so dismissed.
(2) In disposing of any application under this section for leave to present a petition for divorce before the 32 [expiration of one year] from the date of the marriage, the court shall have regard to the interests of any children of the marriage and to the question whether there is a reasonable probability of a reconciliation between the parties before the expiration of the 33 [said one year].
Section 12 in The Hindu Marriage Act, 1955
12 Voidable marriages .
(1) Any marriage solemnised, whether before or after the commencement of this Act, shall be voidable and may be annulled by a decree of nullity on any of the following grounds, namely:
12 [(a) that the marriage has not been consummated owing to the impotence of the respondent; or]
(b) that the marriage is in contravention of the condition specified in clause (ii) of section 5; or
(c) that the consent of the petitioner, or where the consent of the guardian in marriage of the petitioner 13 [was required under section 5 as it stood immediately before the commencement of the Child Marriage Restraint (Amendment) Act, 1978 (2 of 1978)*], the consent of such guardian was obtained by force 14 [or by fraud as to the nature of the ceremony or as to any material fact or circumstance concerning the respondent]; or
(d) that the respondent was at the time of the marriage pregnant by some person other than the petitioner.
(2) Notwithstanding anything contained in sub-section (1), no petition for annulling a marriage
(a) on the ground specified in clause (c) of sub-section (1) shall be entertained if
(i) 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; or
(ii) the petitioner has, with his or her full consent, lived with the other party to the marriage as husband or wife after the force had ceased to operate or, as the case may be, the fraud had been discovered;
(b) on the ground specified in clause (d) of sub-section (1) shall be entertained unless the court is satisfied
(i) that the petitioner was at the time of the marriage ignorant of the facts alleged;
(ii) that proceedings have been instituted in the case of a marriage solemnised before the commencement of this Act within one year of such commencement and in the case of marriages solemnised after such commencement within one year from the date of the marriage; and
(iii) that marital intercourse with the consent of the petitioner has not taken place since the discovery by the petitioner of the existence of 15 [the said ground].
(i) Non-disclosure of age and factum of having major children by husband at the time of marriage amounts to fraud and suppression of material facts having bearing on marriage. Marriage founded on fraud from very inception is a nullity; Sunder Lal Soni v. Smt. Namita Jain, AIR 2006 MP 51.
(ii) Misrepresentation as to the age of the bridegroom made to the mother who acted as an agent and the daughter consented for the marriage believing the statement to be true. It was held that the consent was vitiated by fraud; Babui Panmate v. Ram Agya Singh, AIR 1968 Pat 190.
