Importance of Legal Research

1. Precise Answers Lead to Confidence
Legal research is your secret weapon for finding precise answers and boosting your confidence in court. With thorough research, you're armed with accurate information, enabling you to present your case convincingly. This preparation helps you craft compelling counterarguments and navigate the legal process smoothly.
2. Deep Understanding of the Case
A lawyer must know every case detail to communicate effectively with the court and clients. Legal research equips you with the knowledge to answer questions and explain your position. This expertise strengthens your case and enhances your reputation with clients and the court.
3. Breaking Down Complex Issues
Legal research simplifies complex issues by filtering out unnecessary data. You can analyze different aspects of the issue and develop strategies to address them. This process often reveals that what seemed initially complicated is manageable, allowing you to handle the case easily.
4. Adding Value to Your Case
A well-researched case demonstrates your dedication and enhances your credibility. You show the court your commitment to the matter by presenting solid evidence and insights. This preparation empowers you to anticipate various scenarios in court and present relevant proof effectively.

Record the Facts and Create a Research Plan
Approach legal tasks with confidence by starting with a solid process. Begin by identifying and understanding the facts of your case. Answer questions like:
What is the legal issue?
What are the case details?
What jurisdiction is most relevant?
Do you need state or federal case law?
Record these facts in a case management tool to develop a course of action and determine where to start your research. Skipping this step may be tempting, but it saves time in the long run and helps you efficiently manage multiple clients. Plus, you'll need the recorded facts to file motions or briefs later. With your facts recorded, create a research plan to guide your source-gathering efforts.
Understand the Precedent in Your Jurisdiction
Pay close attention to the geographical location where your legal issue will be resolved. Is the precedent controlling in your jurisdiction, or is it merely persuasive? Understanding this will help you focus your research efforts effectively.
Gather Sources of Law
Once you have a plan, gather relevant sources of law. Start with secondary law materials to get up to speed on what experts have to say about your topic before searching for primary law. Secondary sources provide valuable analysis and insights, such as:
Practice guides
Legal treatises
Law review articles
Scholarly journals
Legal news
Jury instructions
Legal dictionaries
Encyclopedias
Once you have a solid understanding, move on to primary sources, which are formal documents that establish the law, such as:
Case law
Orders
Decisions
Statutes
Regulations
Constitutions
Treaties
Check for Good Law
Before wrapping up your research, ensure you've used “good” case law that has been treated positively in court. As you collect case citations, check them to see how they've been treated in court. Legal research software can help with this, but reviewing your citations once your research is complete is also a good idea to catch:
Any gaps
Changes
Oversights
Report Results and Check for Gaps
Compile your research into a legal memorandum to identify gaps that could present later consequences. A legal memorandum should state the facts of the case, identify the issue, apply “good” law to the facts, predict any counterpoints, and assess the outcome. If you're struggling with legal writing, consider supplementing your efforts with a book from a local law library.
