I know of one similar case. It got dismissed in the wife's new state, but only because he had filed in their home state. He had gone into the hospital for an issue & when he got out a week later, she was gone with the kids. Becasue he ASKED his state to take juridsiction over the kids, he was able to challenge it in the other's new state. BUT if you haven't yet filed, then you don't have this one thing that he needed to have in order to get the case dismissed in her new state.
