A more thorough explanation:

Divisum imperium is a Latin term that means "a divided empire." It refers to a situation where two different courts have jurisdiction over the same area, but at different times. For example, in some places, the common law court has jurisdiction over an area when the tide is low, while the admiralty court has jurisdiction when the tide is high.

This term is often used in maritime law, where there are different rules and regulations that apply to ships and boats depending on whether they are on the water or on land. In these cases, the courts have to work together to ensure that justice is served and that the law is applied correctly.

Overall, divisum imperium is an important concept in the legal world, as it helps to ensure that everyone is treated fairly and that the law is applied consistently.
