Most times there is a stipulation in the paperwork saying she has to have your permission to move over a certain distance away and she has to give you at least 30 days notice of a proposed move.

Not that you have to stop it...but there should be options there for you

Cori's decree says that he is to have 30 notice of move and she can't move more than 50 miles from her current residence (not that she complies with any order anywhere but...at least it is there)

We also meet her half way for drop offs and pick ups (so Sioux Falls)...a 3.5 hour drive
