This buyer’s guide takes you through the 6 of the best legal research tools to look out for in 2024, let’s dive in. 

What is legal research software?

Legal research software is any tool designed to assist legal professionals in conducting legal research and accessing relevant legal information. 

As recently as a few years ago, this process still relied on using tried and tested textbooks and dedicated legal news resources. Since then, legal technology has come a long way and there’s now a whole universe of dedicated tools to enable lawyers to conduct legal research better. 

The platforms listed below are specifically designed for legal research and each offers the user a specific research experience. There's a tool for everybody, whether you’re a General Counsel, In-House Counsel or in private practice. 

1. Lexis+

LexisNexis has been a staple for lawyers in the US and UK for many years and it has been increasing its digital offering over the past five years. Their online platform, Lexis+ is a subscription-based legal research and practice management solution. 

Lexis+ combines an extensive collection of legal resources integrated with practice management tools. 

It provides full access to UK, US and international case law, legislation and articles in legal journals. The platform also hosts an online version of the Encyclopaedia of Forms and Precedents and Halsbury’s Laws of England.


Key features of Lexis+ include:

  • Email alerts for legislative changes
  • Historic versioning
  • Legislative timelines
  • Links to cases directly for citation 
  • Smart searching capabilities 

On the independent review site, G2 the platform is rated 4.1 out of 5. The main advantage of the platform is listed as its ease of use, however, users note that it is a more expensive option than some other legal research tools on the market. 


The price of the software is dependent on the number of users, type of users and subscription term. For example, a small law firm paying for a basic profile will pay $105 a month whereas the premium option for this user is $295 a month.
