Free legal research tools used to be a dream. High-quality legal research is a necessity for all law firms—after all, finding the right precedent or statute could give you the edge to win your case—but does it have to be expensive?
In the past, paid research platforms were the only choice, so we accepted legal research tools as a costly-but-necessary expense for law firms. Today, however, the landscape of the industry has changed dramatically, with numerous excellent free tools available online—making free legal research a viable option for law firms looking to allocate funds to other areas of their practice, without compromising the quality of their research.
The only catch? You have to know where to look.
Below, we’ve collected some of the best free legal research tools for law firms. Whether you want to add in new resources to you legal research portfolio or paid legal research is straining your firm’s budget, these free tools will help you present your best case—without the big financial investment.
7 Free legal search engines and databases
The combination of more legal resources being digitized and the development of new technologies means that there’s now an overwhelming amount of legal information that can be found online. The good news? Many of these legal research resources can be found online for free (If you want to really dive deep, browse this comprehensive resource for an in-depth listing of free legal research options.)
Below, we’ve curated seven of the best free search engines and databases help you sort through the information to find exactly what you need for your legal research:

The practice is even smoother via Casetext’s Clio integration, which lets you send a document from Clio to CARA in a single click.
Casetext’s AI search is a paid-but-low-cost option for legal research—though you can try for free with a 14-day trial.
A paid subscription to ROSS Intelligence is another way to leverage AI to enhance your legal research.

Beyond legal databases: Other free research resources
As valuable as legal databases are for your case research, there are also other alternative sources where you can find information and resources to support your legal research. Below, we offer a few free and cost-effective options for help build your case.
1. Primary sources: For going straight to the source
Sometimes, the easiest way to get the information you need is to be direct. You can find many case law and court documents online for free. Legislatures and courts are publishing their own materials, which are sometimes available online as downloadable PDFs—a convenience that until recently has never existed. However, keep in mind that some online versions are not considered “official” and can be refuted by the print version, even though they come from the same source.
Here are some resources you can access directly online:
- US Office of the Law Revision Counsel
- Bound Volumes of the Supreme Court
- Rulings from regulatory and administrative agencies like, Social Security Administration, Financial Crimes Enforcement Network, and the Equal Employment Opportunity Commission
Keep in mind, however, that while this information might be easy to access through primary sources, you’ll likely miss out on the advances search functions or analysis features that you’d find with legal search engines and databases.
Also, older legal information may not be available online yet. In this situation, visiting a library may be helpful as you will be able to find archived legal information that is unavailable elsewhere. Also, you may find potential collaborators in your colleagues (and the librarians) who will be researching there as well. These collaborators will be a great source for information on what arguments worked in the past, and may help you find local knowledge you might not be able to uncover yourself.
If you are a member of a bar association, you should also make full use of the resources available to you through your member benefits, such as:
- Law schools
- Bar Association headquarters
2. Legal blogs: For keeping up-to-date
One of the best ways to become a more efficient legal researcher is to stay ahead of the game. The best way to do that? Maintain your subject matter competency by keeping up-to-date on the latest developments in your practice area by regularly reading legal journals and legal blogs.
A great place to find the best of the best when it comes to legal blogs is through the American Bar Association (ABA)’s annual list, which started in 2007 as the Blawg 100 list of blogs, and has evolved into the Web 100 list of favorite law blogs, podcasts, tweeters, and web tools—a.k.a. a list of the best free law-focused resources and people to follow.
LexBlog—an online network of over 22,000 legal bloggers—is a hub of the latest commentary on the law. Sorting blogs by channels, LexBlog makes it easy to find and subscribe to legal blogs that focus on your specific area of law.
The direct research benefit of staying in the loop? By maintaining subject-matter competency, you’ll already have certain cases and ideas in mind—so that when you’re presented with a case, you won’t be starting from scratch every time.
3. Google Scholar: For searching legal journals and published opinions
While not specifically tailored to legal research, Google Scholar allows you to broadly search and access scholarly literature—which means it’s an effective, free way to find legal documents like patents, legal opinions, legal journals, and articles.
Want the simplest way to search case law? On the Google Scholar main page, select the “Case Law” button under the search box to easily search case law, filtered by jurisdiction.
Conducting smart legal research that’s thorough, accurate, and time-effective makes a big difference to the success of your law firm—but it doesn’t have to be expensive.
Whether paid legal research platforms are out of the firm’s budget or you just want to find cost-effective ways to conduct thorough research for your cases, today’s free legal research resources help you be more efficient so you can serve your clients more effectively—and stay a step ahead of the competition.
