In Mutual divorce, first motion is filed on the presence of both the parties and at that time the case is admitted. In the second motion the divorce is granted. If one of the parties withdraws the petition then they have to give the reason of the withdrawal and if the opposite party contests, then the withdrawal may not happen. Secondly, the opposite party may not come at all for second motion of the divorce and till such time the divorce is not granted. In this case, the affected party has to wait for 18 months from the date of filing of the divorce and then approach the High Court for granting the decree of the divorce in case the other party is not co-operating, provided the case is not withdrawn till that time. There are judgements regarding these cases.
In cas if the matter is written that "All the disputes have been resolved" and then she withdraws the petition, then you can file the divorce on the grounds of cruelty, fraud and breach of trust.
