No Provision for or Discussion of Future College Choice and Costs. Without going into details on each of the points, let me address the first point, because this is far and away the biggest problem for the courts. At the time of the divorce, one or both parents state that they don't need a schedule - they can work the schedule out and both parents are free to see the children anytime they want. This doesn't give the children much assurance. Most children need the security of knowing where they are going to be and with whom.
Holidays become complete chaos with both parties wanting the children at the same time.
Sometimes, the parenting schedule breaks down completely when the first of the parties starts dating. So, do yourself, your ex-spouse and your children a favor. Work out a schedule with clear pickup and drop-off times. Get a copy of the children's school schedule so that you account for all the children's holidays including teachers' conventions, winter and spring break, etc. Once you have a schedule, you can always adjust it to meet each other's needs.
