Filling false case against the family

I have married my own aunt’s daughter on 4/1/20.. she has come from cosmopolitan backgrounds from chennai but not interested to live with us in a taluk head quarter a small town in Karnataka. She lived with us only a countable days. She left the matrimonial house on 2/10/21. Thereafter no communication phone is switched off and when we went personally she refused to see us. And we were unceremoniously sent out. One male baby is born on 15/5/22. Still today they have not disclosed and naming ceremony also made with out our knowledge. This we came to know from relatives. We filled a restitution petition on 29/9/22. They are refusing to receive the court summons. Last week they have filed a complaint on DV act against all our family members. a false allegations made stating they have booked 100 rooms in holiday inn hotel and nearly one crore is spent on marriage. They booked us 20 rooms in holiday inn and we paid 60,000/- to the in-laws. By cash. She had taken back her Jwells and our jwell of 400 gms.
