Definition - What does In Rem mean?
"In rem" is a phrase from Latin, which means “about or against a thing”. In legal terms, it is actually a lawsuit that is not directed toward a particular person, but toward a thing like property. The case must be brought to the court, which is determined by the physical location of the property.

For a court to have in rem jurisdiction, the property must be present in the same county. The judgment given by the court must be enforced upon the property and not to any person. Examples may include partitions, foreclosure of lien (real estate), etc.
