Precaution for possible cases

Hello, 1. Me and my wife were living separately from my parents in another city. In August, we came to my parents home for a festival for a week. But, due to aggressive and abusive behavior of my wife, I had to decide to stay separately. We both decided to rent a house in the same city as her parents live in the same city as well. 2. We stayed there for a couple of weeks but due to our differences we decided to file for mutual consent divorce. a. Our lawyer prepared the draft and finalized it with conditions. b. It was decided that I will pay Rs. 5 lakh to her. After few days wife started demanding Rs. 15 lakh. c. She started threatening that she will file cases. d. Petition is still not submitted, lawyer said it can't be submitted as separation needs to be 1 year. Marriage happened 10 months back. Currently, we are living separately. Wife is staying at same rented house. She is Engineer and works in a software company. My questions are: 1. What precaution or actions I can take to avoid problems of false cases against my parents or relatives. (498A, domestic violence etc)? 2. If wife tries to enter my parents home, do I have any option to stop her? What options I have if she deliberately sends me cohabitation notice? 3. Can she get maintenance in this case? Thank you.
