I want to move 33 miles away with my children to my home town can I change their school district?

If you have joint legal custody, you cannot change schools without your ex’s consent. Since you are not moving more than 100 miles away, you can move, but you will be expected to follow the court orders on current placement, including pick up and drop offs. If your moving away means that you will not be able to follow those court orders, before you move, you would heed to file a motion to modify those orders. If this is a Wisconsin case, there is also a prohibition on either party filing a motion to modify custody or placement for 2 years from your initial orders, unless there is a showing that your children are in imminent danger.
