Jurisdiction and Venue Are Two Different Things
If you or a loved one has an asbestos diagnosis and a work history that crossed state lines, you may have a valid claim in more than one place — and where it is brought can change what it is worth. We work that out before anything is filed.
They are used interchangeably in conversation and mean different things in practice.
Personal jurisdiction is a court's power over a defendant. It generally exists where the defendant is at home — its state of incorporation or principal place of business — or where the claim itself arises out of the defendant's contacts with that state. A company that manufactured insulation in one state and sold it into a jobsite in another may be subject to jurisdiction in both, but for different reasons and to different extents.
Subject matter jurisdiction is a court's power over the kind of case. It is what determines whether a case belongs in state or federal court.
Venue is which court within a system is the proper place, usually keyed to where the parties reside or where the events occurred.
Note that a case must satisfy all three. In asbestos litigation with many defendants, each defendant's jurisdictional position is analyzed separately, which is one reason these cases are more complicated to place than a single-defendant injury claim.
