At what point in the process do you declare your specialization? For example, Defense, Environmental, Real Estate, Wrongful Death, etc.?
Law school is different from college in that you don't have to "declare" a specialization; all law students receive about the same legal education regardless of whether they plan to specialize in something or not. However, there are some law schools that have specific tracks you can follow (for example, UCLA has an Entertainment Law program -

For the most part, though, once you've fulfilled the basic requirements of your J.D., you don't have to declare anything, you just meet with your advisor and the Career Services Office to figure out what you'd like to do after you graduate, and tailor the rest of your classes and internships to give you the most background and knowledge in that field, and improve your chances of employment once you get your degree.
