Concurrent jurisdiction?

Answers:
There are essentially two court systems, federal and state. In order to be able to have your case heard in federal court, there are certain jurisdictional requirements which must be met (e.g., diversity of citizenship -in other words, parties from different states; amount in dispute; whether or not there is a "federal" question involved, etc.). Sometimes, both the state courts and the federal courts both have jurisdiction to hear the matter - that's called "concurrent" jurisdiction. Deciding which court to file in is another matter. For example, if there are local matters involved, you might want to be in state court; if the matter is highly complex, you might want to be in federal court where the judges are, by and large, better because they are appointed, not elected.
