A more thorough explanation:

Definition: A foreign county is a county that is separate from the county where matters arising in the former county are called into question, even if both counties are located within the same state or country. A county is the largest territorial division for local government within a state, and is generally considered to be a political subdivision and a quasi-corporation. Every county exists as a result of a sovereign act of legislation, either constitutional or statutory, separating it from the rest of the state as an integral part of its territory and establishing it as one of the primary divisions of the state for purposes of civil administration.

Example: If a person is involved in a legal dispute in Los Angeles County, but the other party is located in Orange County, then Orange County would be considered a foreign county in this case. This means that any legal proceedings related to the dispute would need to be handled in Orange County, even though both counties are located in California.

Explanation: This example illustrates how a foreign county can be located within the same state as the county where a legal matter arises. In this case, the legal dispute is taking place in Los Angeles County, but because the other party is located in Orange County, any legal proceedings related to the dispute would need to be handled in Orange County. This is because Orange County is considered a separate county, or a foreign county, from Los Angeles County.
