Protection from false dowry case

Hello dear sir/ma'am It's been only three months since I got married, my wife is belongs to hyderabad and i am from gujrat. Firstly we know each other through shaadi.com and decided to get marry. But now i realized that my wife is fraud and just came here to case a false dowry case and loot for money. She told me before marriage that this is her second marriage but after marriage she told me that this is her 3rd marriage and she saying that her first husband was died on exact marriage day. Her second husband was beating her very badly and tried to burn her, there are some burning spots on her skin she shown me but i don't know she is saying truth or false. She told me before marriage that she don't have any family members except his father who is living with her step mother but now after marriage she is saying that her mother is alive and she has a sibling but they both living separate from them and there is not any connection. She never told me before marriage that she was a chain smoker, she was addicted to get drugs, she used to go hokkah bar but now she is revealing everything and after knowing these things i totally broke down. Now she wants to go back to hyderabad and planing to file a false case against me and my family along with her father. Although she doesn't have any marriage documents or we don't have mentioned her name in any kind of documents of our state or voter id or pan card or adhar card or permit card and we haven't even file a marriage certificate in court because according to Muslim low we have only marriage certificate given by kazi. I have faced this thing once in my life and it's gonna be second time. Please dear sir/ma'am show me correct path to save myself and my family from this false dowry case. Thank you
