Since i work abroad holding porrugues passport i sent Rs 6 lakhs for the marriage expenditure and also sent gifts to her worth 1 lakhs of which i have reciepts . After marriage i went back to england. In one months time her behaviour towards me changed she started insulting me and was very cruelty. She even threathened me to file police complaint against me. Seeing her behaviour and threats on whatsapp messages and phone calls i started contacting her friends to find out about her . Her friends told me that she has filed police complaints against her ex bf saying he raped her on pretext of marriage. She is also abusing drugs of which i have her videos and photos share by her friends. In January 22nd 2019 i filed fraud and extortion case against her She counter filed complaint wife abandoned by husband and cruelty against my family in Women's cell south west cant delhi on 25th january 2019. Then my lawyer went there on my behalf and showed them the whatsapp chats and pulled the charges. But Investigator Officer requested me to come down to delhi for signature. Upon reaching delhi for counselling Investigation officer showed me the whatsapp chat and the fake list of expenditure for marriage incurred by my wife totalling 20 lakhs. I was shocked then i explained the investigation officer that i dont wanna live with her and gave him the reason. After carefully examining my case investigation officer gave both of us next date to report at center dwarka court for mediation. Now my lawyer is askig me to show my bank details and all the propert that is on my name and even foreign bank details as we are filing divorce petition in family court and she might ask for maintenance during the proceedings of divorce. Now my question is thats the money which i saves before marriage is counted for msintenance or just my salary. Why they are asking me for 3 years of bank details when my marriage didnt even last for 6 months. Secondly my wife didnt contribute any thing. Not even a penny for marriage nor i took any gifts from her or her family. My wife is 25 years old and has done bachelor's of business administration. The question is how to avoid paying her maintenance or alimony. Court may say pay her maintenance till she find job. What if she doesnt find job then what? What if she make fake medical report or fake expenditure before and after marriage day to day lifestyle. She never worked before or after marriage. Now please help me how not to pay her maintenance or alimony explain me in details. She has warned me saying that she will finish all my money. The question is our marriage didnt last for long nor she contributed anything for marriage or gifts. The money which i saved is from before marriage not after marriage. The salary i earn abroad is not enough for me to pay my bill food and other expenses so please help me how not to pay her any maintenance or alimony during the process of divorce petition.
