To exercise personal jurisdiction over a nonresident defendant, which concept is essential?

• A. The defendant must be domiciled in the forum state.
• B. The defendant must have minimum contacts with the forum state.
• C. The defendant must be physically present in the forum at all times.
• D. The plaintiff must reside in the same forum state.

Answer: (B)

Minimum contacts with the forum state is the essential concept. Under due process, a court may exercise personal jurisdiction over a nonresident only if the defendant has purposefully established significant connections with the forum and maintaining the suit would not offend traditional notions of fair play and substantial justice. This can manifest in two main ways: specific jurisdiction, where the claim arises out of the defendant’s in-state activities connected to those contacts; and general jurisdiction, where the defendant’s contacts are so continuous and systematic that they are essentially at home in the forum. Domicile can justify jurisdiction in some circumstances, but it’s not required for nonresidents and isn’t the core rule here. Physical presence isn’t necessary for jurisdiction either, and where the plaintiff lives has no bearing on the defendant’s in-state power to be hauled into court.
