Can i file a case against wife

Dear Sir/Madam, i got married on 1-10-2017. soon after marriage i faced multiple harassments from my wife, she used to throw at me whatever she has in her hand and used to abuse my mother. late we found that she is not mentally fit. After couple of discussions with elders we decided to separate. so we entered to an agreement on Rs 10 Bond paper. saying that i have to pay 17 Lakhs as compensation to her, in that we paid 2 lakhs in cash on the day of agreement and 4 lakhs in elders joint account on [deleted]. remaining 11 Lakhs we agreed to pay in court at time of divorce. She denied to come for mutual divorce and tried to blackmail to extract more money. she tried to file a case, but not succeeded. So finally i went and filed divorce case in court in January 2019. Soon after that she filed 498-A, DVC , MC and Conjugal rights. Now in front of court she is saying i want to live with husband, in background she is blackmailing for more money. It's been 2 years since it is in court, there is no progress as she is not proceeding for hearing. Could you please suggest me how can i file case against her on base of agreement and elders joint account money. Thanks, Ramanatha
