What is legal research?
Legal research is essential in law practice, encompassing the systematic study and
analysis of legal issues and statutes to address specific legal questions or contribute to
the broader field of law. At its core, legal research involves a methodical process of
identifying legal problems, gathering relevant facts, and finding and interpreting applicable
laws and cases. This process is crucial for lawyers as it forms the backbone of legal
analysis, argumentation, and effective representation of clients. It ensures that legal
practitioners stay abreast of the continually evolving legal landscape, thus providing
accurate and up-to-date legal advice.
While predominantly undertaken by legal professionals, legal research is not confined
solely to lawyers. Law students, paralegals, and even non-lawyers with adequate
knowledge and access to legal resources can engage in legal research for various
purposes, such as personal legal issues, academic pursuits, or professional
development. This wider accessibility has been further enhanced by technological
advancements, especially in artificial intelligence. AI in legal research has transformed
the field, making the research process more efficient and sophisticated. It has automated
and streamlined the retrieval and analysis of legal information, allowing for quicker, more
accurate insights. In essence, legal research is a vital, evolving practice integral to the
legal profession, increasingly influenced by technological progress and accessible to a
broader range of individuals interested in legal matters.

expertise. Furthermore, integrating such technology into case management software
gives lawyers enhanced capabilities to access and manage their case files, track
important deadlines, and automate routine tasks.
Predictive legal analytics
The application of AI in law practice extends to analyzing historical legal data to yield
predictive insights. By examining past case outcomes, judges’ rulings, and legal
precedents, AI tools provide legal professionals with a data-driven foundation to make
informed decisions about case strategies. This predictive approach is instrumental in
assessing risks and forecasting potential case outcomes. Predictive legal analytics also
assists in identifying pertinent legal authorities, evaluating the strength of legal
arguments, and determining the likelihood of litigation success. Such a data-driven
approach to legal research not only saves time and resources but also significantly
enhances the quality of legal services provided.
Legal research technology
AI-powered legal research technology automates several aspects of legal research,
including citation checking, summarizing legal research findings, and analyzing case law.
These AI legal research assistants can swiftly search through vast legal information
databases, identify relevant sources, and summarize key points. These tools are
increasingly effective because they can learn from user interactions, providing more
accurate and relevant research assistance over time.
Customized research platforms
The advent of AI-powered research platforms is ushering in an era of personalized and
customized legal research experiences. Utilizing machine learning, these platforms adapt
to understand legal professionals’ specific research needs and preferences, thereby
