Not sure but prob just making her statement for future court dates (not necessarily that they will appeal or go to next level just that she does not agree with this new order).
Why did she have to sign??? Wasn't a judges order/decision? Weird, here we get decision and that is it, no one signs as it went to judge for a decision and not an agreement between the parties.
Also sounds that she will not appeal now as she prob should have written, do not agree and will be appealing to go to next court?"
My husband taught me (but took years for me to get), deal with what you have in front of you now. You won, as long as she is following new order who cares. Deal with the next blow when it happens, for now...enjoy life...cant always be about court.
