dear preet ,
Give notice to your wife to return back within a stipulated time , Do not forget to mention that she and her family members are threatening to file false cases against u an dur family members . mention all cases .viz 498 A , Domestic violence, 323 etc Simultaneously write to police station of ur area, and her area about the apprehensions of filing such cases . Prepeare urself for the worst and be cool . If she files u have to face the ordeal . The C Govt directive is very clear that police should first invistigate and then arrest. Protect ur parents , High Court normally give anticipatory bail easily. Once ur arrested , u will get normal regular bai; Than harass ur wife and her parents .
