Property Gifted by Parents- what should do during the pendency of Divorce and maintanance proceedings

Got married in 2010 and started living separately in one of the house owned by my parents right next day of the marriage due to problems by wife family. My parents are old and I cannot move far from them as their health wasn't well. We hardly lived together as wife always lived with her parents' house in Chennai. We have two kids. Wife always wanted me to move to her native place Chennai. When i stop her going to her parents house frequently she threatens me that she will commit suicide. It has been a nightmare all these days. wife and her family starts to quarrel with me for simple issues. I tried to explain to my wife but she never understood. In 2019 wife parents asked me to get my parents self owned property to be transferred to me and my wife name so that their daughter will have a hold in living with me. I said NO to them. They started to quarrel with lot of bad words which no one can bear. They took their daughter and my kids to Chennai by train. I tried to convince them but they were firm and didn't listen to me. I got used to problems like this for the last 8 years and i thought she will come back after a month, they all went in a train that was booked already and that gave me a doubt why are they doing this. wife switched off the mobile. After a month she called me by WhatsApp and asked me for her jewels and education certificate that was in the house. I said her to take it. She came alone one fine day without kids and her parents were staying somewhere in a hotel. Me and my parents tried to convince and make her understand but she didn't even listen but threatened that she will commit suicide. We asked her to bring her parents to give the things but she denied. At last, I took a video and gave all the things. She took all her things and left the house and said to me that " I will show what i am capable of". She also took TC from kid school without my knowledge. In 2020 i received a court notice for RCR from Chennai family court saying all false allegation about the whole family and she called me to come and live in Chennai. Counselling person advised her, but nothing worked. Sent friends for patch up but failed. I lost my mother in 2020 covid and then my father was bedridden for 18 months due to lung failure. I called her before and after my mother's death to withdraw the case and come and live with me peacefully but she denied. She just came a day after my mother's death and went. I filed divorce in 2021 after she filed maintenance. I am saving every month for kids in their account. i am ready to pay all expenses for kids. My father gifted his self-owned property to me to pledge as he is senior citizen loan was not given. Should i show this property in assets for maintenance. Having solid proof for all her allegations. how to be prepared. I am doing business & IT return of 50,000/month. How much Maintenace is awarded?She keeps saying she wated to live with me but i dont want her again. case in trial but no evidence submitted by her.
