Attorney multijurisdictional practice is an increasingly important topic for attorneys. Thus, it is essential to be aware of topics such as, admission by motion, reciprocity, and pro hac vice admission. The web page of the ABA's Commission on Multijurisdictional Practice is a great place to start. The page includes ABA reports, recommendations and charts containing information on state rules. It is a very useful site!
