I got the mutual divorce in the first marriage and last year 2019 got married to a divorcee girl and got separated in 2 months of time. The reason is the girls is abnormal as her mental disorder is hided before marriage. She left the home on her own accord. Their family members has not paid any heed towards the medical treatment for her. On nov 2019 i have sent a legal lawyer notice to her but no reply from them. Their family members are harassing us for reunion. Subsequently i have filed a petition before the hon'bl family court at Chennai. Knowing that we have filed the petition at the court, my wife her mother and relatives went to the police station and given complaint against me. The police is now calling me for inquiry . The case number yet to get generated at court. Without case number the police is calling me for inquiry . We are separated from apr 2019 onwards, and till now they have not given any police complaint against me nor approached the courts for divorce. I want to know the following thing 1) I dont have the case number as it has to get generated from the court, if i would have the case number then i shall ask the Police that the case is in court. It may take another max week time to get the number. In this case do i need to appear before the police. 2) Whether the police can book me for domestic violence after getting the false complaint. 3) I have already sent Lawyer notice to her and 2 weeks back filed a petition at family court and the case number yet to get generated. 4) Do i have to appear for inquiry at police station for the complaint given by my wife two days before i.e on 24 jan 2020.
