Hello, Jaime. When you got divorced, you should have had a Joint Parenting Agreement (JPA) that detailed what the parenting time was and the issues around it. It sounds like you have that since there are specific periods of time during which you are supposed to have custody of the children. The JPA becomes, in effect, a court order that you are both bound by. If one of you violates that order, it can be reported to the court and relief sought from the court for the violation of the JPA. It is up to the Judge exactly how the situation will be remedied (it could be anything from a scolding to a reworking of the JPA to make a new one, to the most extreme recourse of being held in contempt). I should note that it sounds like one of you moved away, and it is possible that this could constitute a "significant change in circumstances" which could lead a Judge to ask for an updated JPA which takes into account the distance between the parties. It should further be noted that the JPA and/or the Marital Settlement Agreement (MSA) should specifically say which court's jurisdiction is to be used in all future matters. If an Iowa court is to be used, you should seek help from a licensed Iowa attorney for further guidance; likewise, if an Illinois court is to retain jurisdiction, you should contact an Illinois attorney for additional help. I hope this helps get you on the right track in your matter.   (This answer does not create a binding attorney-client relationship and should be used for information purposes only.)
