When someone is hurt by the negligence of a corporation, the injured person may have multiple options as to where to file his or her claim. Generally speaking, most such claims are filed in a state court in the county in which the accident occurred.
However, in some cases, the plaintiff may prefer that his or her claim be filed in federal court, providing that there is diversity of citizenship between the parties and that personal jurisdiction exists.
The defendant in a federal case may resist jurisdiction and/or venue for one reason or another. In such an event, the district court in which the action is initially filed must decide whether it does, in fact, have diversity jurisdiction over the case and whether venue is proper in that particular court.
