Wife has send me the legal notice for domestic violance and dowry

Hi, I am married to her for last 9 years and we have 4.5 yrs old daughter. She has send a notice putting false allegation against me n my parents for dowry and domestic violance. We were staying in UAE for 8 yrs and recently moved to India as she wanted to stay in India. We had arguments and hence one day her parents asked me to leave the house. After couple of months she send this notice, she is not allowing me to talk to my daughter and not letting me see her. In the notice she has put allegation that I had a relationship with a collegue in Dubai. She took access of my email ids and social media acs and created false chats and attached in the notice. As well we both bought two property in Delhi in joint name and both our parents helped us in buying it along with a housing loan, but she has put it as dowry taken from her parents. This money was given in 2016-17 for the property. All these allegation are fake and instead she has beaten me up on several occasions but I didn't make any official complaint as I never wanted to lose my daughter. I don't know what to do next and how to react. I mean currently working in bangalore and she is not and she is staying in different city with her parents. Complaint is made in delhi court. I want to stay with the family the only reason is my daughter and her future. Pls advice.
