To hear and resolve a dispute, a court will need to have personal jurisdiction over the defendant. If the defendant resides in the state or does business in the state, a court will have jurisdiction over them. If the defendant does not reside or do business in the state where the plaintiff wants to sue them, the plaintiff still may be able to establish jurisdiction in limited situations. They can serve the defendant with the summons and complaint while they are in the state, or they can show that the defendant has some minimum contact with the state, such that it would be fair for a court in the state to have jurisdiction. Special rules apply to car accident cases, which always can be filed in the state where the accident happened.
