Legal Definitions - conterminous

Definition: Conterminous is an adjective that describes two or more things that share a common boundary or are enclosed within a common boundary.

Examples:

• The surveyor set a new line between the conterminous counties.
• All 48 conterminous states of this country are located within the same boundary.

The first example illustrates how two counties share a common boundary, which makes them conterminous. The second example shows how all 48 states in the United States are enclosed within a common boundary, making them conterminous as well.
