Wife's intentional filing of dv petition

My wife has filed a dv case against me and my family members in a court which is about 150 km away from my house and also from her parental house by showing to the honourable court that she resides at her brother's house which is nearer to the court. The wife has done this only for putting me in more financial difficulties since she knows very well that I am not having good financial position for the timebeing. She filed this dv petition only after I informed the District Legal Service Authority about her torture to me along with her boyfriend. She has intentionally avoided the notice of DLSA and filed a suit against me and my family members in a court which is far away from my house. It may be noted that no Violence has been faced by her from my side and my family side during the last 7 years of marriage. No FIR has also been lodged by him in my Police station during the last 7 years of marriage. Please suggest me the procedure to quash her false petition or any step as you think better for me in this situation. Thank you so much.
