On 5th.june 2019 my wife left my house when i was out stationed.Till date i am trying my best to get back her.Recently she threatened me over phone for divorce saying that "you will get notice within 3 month" and also threatening me by saying that "you will not contact me by any means here and there,if you do this i will call police".She has taken a fixed deposit amounting Rs.7.5 Lacs which amount is paid by me but F.D is made in her name. i am worried that she may also file case of domestic violence also.She has got some injury in her hand in the month of march 2019. I have one flat at present. Now my question is : 1.Can she file divorce so quickly. 2.If she file any domestic violence case what will be my protection. 3.How can i proof i am not guilty in case of domestic violence case file by her. 4.Is she eligible for maintenance or can claim property. 5.How i will be able to get back my money which she has taken. 6.Can she file 498 case,then what will be my protection process. 7. Can i get anticipatory bail from any court. Please suggest.
