Stop payment cheque

My wife had filed false 498 on me 7 months back. I was in custody for 5 days .during which some deeds were signed by my dad and gave cheque to my wife as permanent alimony of very very huge amount and for which they will take this false 498 back and mcd will be filed . I was given bail as most of the cases like ipc 325 354 was not prooved by medical report . Investigation for 498 was proposed . And jurisdiction issue . I was given bail . Then we returned everything in fact she robbed me of my own things too . Then we tried a lot for mutual divorce but their conditions were not acceptable . They wanted only momey . So we stopped payment the cheque . Now they have sent us a legal notice for the same . Chargesheet for 498 has come to court . Divorce filed by me 1 week before. Hearing on 1st week July . Cheque and deeds were signed by my dad when I was in custody for my life he sighned . Now how should we fight . Alimony has to be decided by family court and that too by husband . Can they file ni 138 as they have sent statutory legal notice . Regards . Thank you
