Answer: The family would have to relearn the court system.
Explanation: if there is absence of national court in a country, family moving from one state to another would have to relearn how the court system in the new state works, because the law that is used by a particular state might be different from another, and only a national court can affect all states. Therefore, the moving family would have to relearn the court system in the new state because they are guided by different constitution.
