This video by Dr. Julie Simpson from American Military University explains the rationale behind writing case briefs and explaining how to develop each section of a brief.
How to Brief a Case and Case Brief Example: The Wildenhus Case
These two pages use the Wildenhus Case as a sample case for a legal brief. How to Brief a Case explains the questions about the case that will be answered in each section and Case Brief Example is how the brief looks once it is fully written.
As each of these briefs is put together and formatted differently, please follow your professor's directions as to how you should write your brief.
