Walk It Through: The Parenting Plan
Two parents in two towns, a request for the school records, a job offer out of state, and thirty days' notice.
Separating parents each want the children most of the time. One assumes the mother will be preferred.
Two things a person in this spot might do. Picking one shows what the law says about it.
A custody plan between two fit parents. A history of family violence changes how the court arranges visitation, which these steps do not walk through.
A practice walkthrough, not a prediction of how any real one will go. Legal information, not legal advice.
