What does the concept of "purposeful availment" refer to in personal jurisdiction?

The concept of "purposeful availment" is crucial in determining whether a court in one state has personal jurisdiction over a defendant located in another state. It refers to the requirement that a defendant must have engaged in activities that are deliberately directed toward the forum state. This means that the defendant has taken some action that connects them to the state, allowing them to reasonably anticipate being haled into court there.

Purposeful availment ensures that it is fair and just for the courts of a state to exercise jurisdiction over a defendant based on their intentional activities within that state. Factors that are commonly considered to establish purposeful availment include conducting business, entering into contracts, or committing acts that cause harm within the state.

This concept helps to protect defendants from being subject to litigation in jurisdictions where they have no meaningful ties or engagements. In contrast, simply being present in the state at the time of litigation, being served personally, or residing in the state are not sufficient on their own to establish personal jurisdiction without evidence of purposeful availment.
