Finding conflicting opinions within a state, among states, between federal circuit courts or between different countries often provides a good starting point for choosing a paper topic.
A federal case search in Westlaw or Lexis for "split w/5 circuits" will provide some example cases. Other strategies include exploring dissenting opinions or certiorari petitions or cases of first impression to find unsettled areas of the law. Try a case law search of "first impression" to find relevant state or federal cases.
Law firms or professional associations sometimes release newsletters about legal current events that may affect their clients. Luckily, there are databases and websites which gather and publish these newsletters and make them accesible to everyone.
