@ Author DV has a retrospective effect as well .
Even if your wife stayed with you for 2-3 days she can file a DV case .and also 498 A case and rope in all your relatives from all parts of the coountry and than they would have to seek anticipiatory bail in the case of 498 A . Although your relatives would be fuming and turning red at the false allegations being laid out .
The reliefs in DV are
1. Maintanence .
2. custody... when she files DV only she can apply for custody and you can only get visitation rights in this as this is a gender biased law . Else you have to apply for custody in gaurdians and wards act
3. Right to residence .she can park her aXX in your place of residence sit on your lap , perform a lap dance kiss you even though she does not love and you cant even throw her out since
4. She can ask for a protection order .
