Ask relevant questions. Any research into legal matters should begin with a review of the facts of the case. To make certain you have a thorough understanding of the details at hand, ask yourself the 5Ws: who, what, where, when, why.
Determine the jurisdiction. After you have established the necessary details of the legal issue, you will need to determine what jurisdiction is involved. Is the matter under research governed by federal or state law? For legal questions arising from the states, which state or states issued the law? For federal legal questions, you will need to determine the relevant Circuit and District courts.
Consult secondary sources. Secondary sources are sources which analyze, critique, or discuss legal issues. In other words, these are resources about the law, not the law itself. Common forms of secondary sources include articles published within legal periodicals, legal dictionaries, and legal treatises.
Consult primary law. Primary law is the actual text of the law as issued by official government bodies. These laws include statutes, cases, and regulations. Constitutions, such as the U.S. Constitution, are also considered primary law.
Confirm your authority is still good law. Use a citator, such as Shepard's, in Nexis Uni, to confirm your case remains good law.
