1)once the summon converted into Mutual divorce ,is it possible for my wife to change her mind withing 6 months and deny the Divorce?If yes, what should be my precautionary measures?
Please note that summon cannot be converted to Mutual consent divorce, you may have to withdraw the present petition filed seeking dissolution marriage by a decree of divorce on other grounds and file a fresh petition for divorce on mutual consent by both of you signing the petition as petitioners.
If she changes her mind at the time of second motion in the MCD case, you cannot force her and you have no option than to file a divorce petition again afresh on the previous grounds, the dismissal of MCD due to her fault may be mentioned as additional ground of cruelty.
2)my wife is saying though she will give me divorce mutually but she wanted me to stay with her during these 6 months for few days in a month .Now my question , what kind of precautions i should take where the family court should not reject/deny the divorce ?
The six months cooling off period ordered by court is for the purpose of reconciling. If understanding develops and you both would like to shed away the differences and desire to continue your married life, the petition on the second motion, i.e., after six months, shall stand dismissed as not pressed by parties. So the possibilities are that if you accede to her desire, the above may result, so think what kind of precautions to be taken. If you are firm enough to divorce her, do not accede to her request or conditions.
3) i have agreed to pay monthly maintenance to my wife instead of lumpsum , i hope this will be grated in the law of court.I dont want to pay full and final.
You can inform the court that you are willing to pay only monthly maintenance and not the lump sum amount, the court will consider your request.
