This article explores what legal research tools are, its forms, and the free and paid options the internet has to offer.

What are Legal Research Tools

Legal research tools are specialized applications or platforms that aid law students and lawyers alike in fact-finding tasks. This is very important in making sure that the material you are using in class is the most updated and accurate one there is. It also helps you make informed case analyses and case digests when required.

Forms of Legal Research Tools in the Philippines

Legal research tools can take many forms from hard copies to online tools, from books to digest collections. Here are just some common forms we see in law school:

Traditional Legal Research Tools

Traditional forms of legal research tools include printed law books, codals, case digests, and legal encyclopedias. They have long been the backbone of law school study and practice, providing reliable, tangible source for legal interpretations and precedent. Below are other forms of traditional legal research tools:

• Codals

Codals are your bibles in law school. It is usually referenced in your syllabus and even by your professor because it is the most basic copy of the law. Codals like the Revised Penal Code or the Civil Code usually come in pocket-book size so that they are easier to carry around.

• Commentaries

Commentaries, on the other hand, contain the interpretations of legal experts on the legal provisions we find in your codals. These clarify, critique, or provide interpretations of legal statutes as well as developments in case law. 

Commentaries such as those written by Atty. Tolentino on Property Law or Atty. Reyes on Criminal Law are just some prominent examples of commentaries you should look out for in legal research in law school.

• Full-Text Cases

Full-Text cases are those usually assigned to us in law school because they provide binding interpretations of the law. When a legal provision is ambiguous and parties don’t know how to apply it to their legal problem, the Supreme Court steps in to clarify the law through various statutory construction principles or sometimes, even based on equity.

However, as legal education evolves and technology reshapes how information is accessed, students are gradually shifting from printed references to digital platforms that offer faster and more convenient research options.

Digital Legal Research Tools

Digital legal research tools refer to online databases, case repositories, AI legal assistants or tools, and citation managers that streamline the process of finding and analyzing laws and jurisprudence. These platforms make legal information accessible anytime, anywhere.

• Digest Databases

Digests contain a summarized & organized versions of the cases we are tasked to read. While we are highly encouraged to read the cases in full, sometimes we have to be efficient when there are tons of readings to go through. Thus, reliable digest databases such as Digest PH offer free case digests and even full-text cases to ensure accuracy.

• E-Codals

E-Codals are simply digital versions of the codals we have. These make it easier to copy-paste legal provisions to reviewers for quicker reference.

• Legal AI Tools

Legal AI tools are platforms that help in making legal research easier. By simply typing in a legal research question, you can instantly have access to all resources connected to your research topic. 

For instance, Digest AI has multiple answer modes to choose from, comprehensive, recit-ready, and even bar exam. In this way, the legal AI tool can properly tailor its answers to suit your every legal need.

The table below compares these tools based on their type, accessibility, and key features, helping law students and legal professionals choose the best option for their workflow.

In a single file, dump all your research findings, comments, and citations in one document. Don’t worry too much about organizing them first as long as you can keep track where one concept starts and where one ends. 

4. Summarize your Research Findings

This last step has 2 objectives: organizing your research information and looking for the gaps in your research. The latter objective is achieved when you notice that there are still some questions left unanswered by your already existing research. This makes it easier to recall the research you did especially in exams and recitations.
