How could having no national court system affect a family that moved from one state to another?

The family would have to relearn the court system.

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