While moving application in DV for custody of the child is one of the options, it has got its own problems. You would do that and ask for custody. While doing so, also file independent custody case along with visitation rights. Because, in the latter case, which is initiated by you the orders are permanent in nature. In the former case, if she stops to attend DV case or withdraws it after you get interim custody orders, then along with the withdrawal of case, all the orders passed during the pendency of cases become ineffective.
