A friend and his STBX has been to mediation a few times and have settled several issues. They currently have 60/40 custody (mom w/60) and she is threatening to move the children out of state. She became employed after separation and the move would be a personal move and not a job related. Her reason to move is to be with the boyfriend w/whom she cheated with on her husband. The father is paying child support (which is not from the worksheet) and is actively involved in their lives and does not miss any of his scheduled visitation.
Under what circumstance could she take these children out of state?
