My x-wife wants to move 120 miles away with my 3 kids. In our divorce papers it states that neither parent can move more than 60 miles from the other. It also states that a parent can give resonable notice to the other parent and court. Does this mean she can take them and what is resonable notice? Can I dispute it?

It means she has to give notice before the move of 60 miles or less. It means she can not move without your permission, if she has notified the court, you file a objection to her move so that she can not move. If she does, you file a motion to order her to return the kids to the local area.

It means that only the court can approve such a move. And that before moving, notice must be given to give the court with time to decide whether to change the existing order or not.

If you have been an active part of your children's lives and refuse to agree to the move, it is unlikely the court will grant it. So she will be faced with a choice of not moving or giving you primary custody.
