There is no default. You have a badly written PP and you need to take action to fix it either by agreement or mediation. If you cannot agree and try to go to court, the Commissioner wll not be happy with you so you should do something to resolve the issue without court action.

If the parenting plan states that the father is to "pick [the children] up from the mothers home by 3:45pm", it would seem to me that it would be the mother's responsibility to have the children ready to be picked up at her house by 3:45 PM.
If there is a new school, the parents likely need to work together to change the parenting plan to meet the new reality.
On another hand, some parents are inflexible and are always looking for ways to cause troubles.
You should review the parenting plan carefully to see what its provisions on dispute resolutions are.
No one is required to pick up if the parenting plan is silent on that issue. You may have to file a motion or petition for a minor modification to remedy this defect. It’s always best to consult with a good family law attorney to discuss the details before you act.
