Importance of Legal Research

The Importance of Legal Research can be an excellent help for lawyers to streamline their matters or address an issue without any significant trouble. 

1. Gives Accurate 

Good legal research covers more than half of the matter and gives you more confidence in presenting the whole issue in front of the authority without any trouble or second thought. It helps you in winning the matter without any complications. With proper research and information, you can easily fight back against the opponent with strong counterarguments. 

2. Gives Full 

Knowledge about the case, whether it be a matter or a general issue, a lawyer must have answers for the same in front of the jury. It can be a question or a statement, but as a lawyer, you should be answerable to the authority to maintain a good image of yourself in front of your client as well as the authority. The lawyer must explain the information and evidence of the matter the lawyer is presenting. Good legal research enables lawyers to make the most of a matter or case. 

3. Simplifies Issue 

Unnecessary data gets eliminated when you go through the legal research process. You can analyze and understand the different aspects of the issue and how to deal with them. Some matters may appear complicated at first, but with proper legal research, they can be broken down into simplified, manageable pieces, which helps lawyers easily navigate the whole complication without much trouble. 

4. Provides More Value 

A strong case is easily presented and showcases the lawyer's hard work over the past days and months. It reflects a good image of the lawyer or attorney. Legal research helps deliver more value to the authority by submitting core evidence and details related to the matter. Once you have the research work done, things get clearer as you understand the different situations that can take place in the court. It gives you more power to present relevant proof.

8 Tips for Legal Research

1. Use Otio to Simplify Your Legal Research 

Content overload is a real problem for knowledge workers, researchers, and students. Legal researchers are no exception. Luckily, Otio provides one AI-native workspace to help researchers collect, extract, and create from a wide range of data sources. You can collect data from bookmarks, tweets, books, and even YouTube videos. 

Once your data is collected, Otio helps you extract key takeaways with detailed AI-generated notes and source-grounded Q&A chat. Finally, Otio assists you with creating draft outputs using your collected sources. This not only helps you go from reading list to first draft faster, but it also enables you to write research papers or legal memoranda with ease. 

2. Gather Critical Information About Your Legal Issue 

Before you dive into your legal research, take a step back and gather critical information about your legal issue. Recording the who, what, when, where, and how of your case will help you establish a more focused and streamlined research process. 

3. Establish Your Legal Issue and Your Goal 

Use the critical information you gathered to pinpoint your legal and ethical issue and establish your research goals. This will help you identify what you already know, what you need to find out, and the jurisdiction within which you need to conduct your research. 

4. Learn and Understand the Precedent in Your Jurisdiction 

Pay close attention to the jurisdiction where your legal issue will be resolved. Determine whether the precedent you find is controlling or merely persuasive within your jurisdiction.  

5. Determine the Type of Legal Sources You Need 

Legal research involves three types of sources: 

  • Primary, 

  • Secondary 

  • Tertiary. 

Primary sources establish the current law and include constitutions, statutes, treaties, regulations, and case law. Secondary sources interpret legal principles and summarize the state of the law. 

Examples include law review articles, practice guides, and legal treatises. Tertiary sources provide basic background information and include dictionaries and encyclopedias.  

6. Begin Your Legal Research with Secondary Sources 

Starting with secondary sources provides you with the necessary background information and saves time by leveraging the expert research that others have already conducted. 

7. Check That You’re Using “Good” Law 

Verify that the cases and statutes you find are still valid and relevant using a citator tool. This will help you avoid relying on overruled or unconstitutional laws that could undermine your credibility.  

8. Report Your Results to Check for Gaps 

Compile your research into a legal memorandum to identify any information gaps. This will help you make an informed assessment of the outcome of your case.
