However, she would like to save her marriage and wants to file a unilateral withdrawal application before the family court stating that she wants to save the marriage. Can she file an affidavit in advance to withdraw her consent given earlier to MCD? IF yes, what is the procedure. Since the case is pending in the family court in the boy's native,the boy's father might try and influence any one to get this divorce through, hence the girl wants to take all the precautions and wants to pray before the judge to dismiss the case.
