Many custody orders will provide whether the parties are entitled to vacation time with the children in addition to their regularly scheduled time as well as any relevant notice provisions. A standard provision includes at least thirty days advance notice to the other parent and all details of the itinerary/contact information for the children while away. Parties may want to consider going into additional detail about any restraints on travel, particularly out of state or out of country. It's good practice to provide that international travel may only be by written consent of both parties or court order. Parties should pay attention to which country the other parent intends to travel to and whether that country belongs to the Hague Convention on Civil Aspects of International Child Abduction and would recognize a U.S. custody order if necessary.
