Below are a few examples of more commonly-used legal references. Please note that the APA Publication Manual is the best place to go for help with referencing a variety of different legal sources. Please refer to Chapter 11, starting on page 353.
Additionally, APA refers back to The Bluebook: A Uniform System of Citation (2015). While a subscription is needed to see the full manual, Bluebook has a Quick Style Guide for basic legal references.
Cornell University Law School has a very comprehensive guide and eBook on citing legal sources.
