Define in personam jurisdiction.

• A. The Defendant Has Physical Presence In Or Contacts With The Forum State
• B. The Property Lying Within The Forum State
• C. The Court’s Power Over Disputes Involving Property
• D. The State’s Legislative Authority

Answer: (A)

In personam jurisdiction is the court’s authority to adjudicate the rights of a particular person, based on that person’s presence or meaningful contacts with the forum state. When someone is physically present in the state or has purposefully availed themselves of the state's benefits and activities, and the lawsuit is properly served, the state can exercise power over that person’s rights. This concept rests on the due process requirement that exercising jurisdiction be fair and reasonable given the defendant’s connections to the state. This is different from jurisdiction over property located in the state (in rem or quasi-in-rem), and it’s not about the state's power to make laws (legislative authority). So the best description is that the defendant has physical presence in or contacts with the forum state.
