I don’t think “jurisdiction” is quite the concept you’re looking for. That has to do with whether a court has the authority to adjudicate a controversy and bind the parties to its judgment. What I think you’re probably asking about is “choice of law,” which is how to decide which state’s substantive law applies to resolve a particular controversy that involves more than one jurisdiction. It’s impossible to summarize that analysis, unfortunately–the Restatement on that subject is three volumes long, as I recall, even without the appendices. Heck, most law schools teach major courses on conflict of laws.
minty green,
Please explain in nice small words for the slow among us why one is responsible for following laws in a state in which he is not in?
One is not “responsible for following laws in a state in which he is not in.” One is responsible for adhering to the laws of another state’s when one’s conduct is directed towards that other state.
How is one completing a legal transaction action directed towards another state?
