My question involves a child custody case from the State of: Indiana

Our case is in Southern Indiana. My ex moved to Chicago Illinois. Now that he has moved from the state would I be allowed to move out of state as well? If that is a possibility what would I need to do so that I could move?

I am remarried and my husband would like to go active in the Army which would mean he would most likely be stationed out of state, but he won't because we don't know if I would be able to take my kids with us and we want to stay together as a family.
