Free Legal Research: The Best No-Cost Tools and Databases
You can answer a surprising share of legal questions without paying a cent. Here are the free databases worth knowing, how they stack up, and how to use them together.

Where Can I Do Free Legal Research?
More places than most people realize. The free tier of legal research is genuinely capable: CourtListener and Google Scholar cover court opinions, Cornell’s Legal Information Institute and official government sites carry statutes and regulations, and Justia offers a broad, ad-supported portal with a topic layer on top. Add free on-site access to the paid platforms at public and law libraries, and a determined researcher can get a long way without a subscription.
How to Do Legal Research for Free
The method matters more than the tool. Work from the primary source outward: find the controlling case law free or the relevant statute, read it yourself rather than relying on a summary, and note the citations it points to. Use a topic overview (Justia or a reputable explainer) only to orient yourself, not as authority. Finally — and this is the step free tools handle worst — confirm a case is still good law before you rely on it, which usually means checking how later courts have treated it.
Is There a Free Alternative to Westlaw?
No single free product replaces Westlaw, but a stack of them covers a lot of ground: CourtListener and Google Scholar for cases, Cornell LII and government sites for statutes and regulations, and library access for the rest. What you give up is the editorial layer — curated headnotes and secondary sources — and a full-strength citator. For many questions that is an acceptable trade; for a high-stakes filing, it is a real gap.
The 9 Best Free Databases, Ranked
Free and low-cost tools from our verified directory, roughly in order of everyday usefulness for case-law research:
A free legal-research site run by the nonprofit Free Law Project, hosting millions of court opinions plus oral-argument audio and a searchable docket archive. Free to use, with an API and bulk-data downloads.
Google Scholar's Case Law mode provides free full-text search of US federal and state court opinions alongside scholarly articles. Free to use; coverage and citation depth are narrower than paid platforms.
A free public resource from Cornell Law School publishing the US Code, Supreme Court opinions, the Code of Federal Regulations, and plain-language legal explainers. Free to use, run as a nonprofit within the law school.
A free legal-information portal offering US case law, codes, regulations, and a lawyer directory. Free to use and ad-supported.
A Harvard Law School Library project that digitized US case law and makes the data freely available for download and via an API. Free to use; primarily a bulk-data and research resource rather than a day-to-day search tool.
A free browser extension from the Free Law Project that saves documents users buy on PACER into a public archive on CourtListener, and shows when a filing is already available for free. Free to install and use.
The federal judiciary's official Public Access to Court Electronic Records system, providing case and docket information from US district, bankruptcy, and appellate courts. Registration is free but most page views and document downloads carry per-page fees.
Library Access: Free Westlaw and Lexis
The most underused free resource is the library. Many public libraries, and nearly all county and state law libraries, provide free on-site access to Westlaw, Lexis, or both, plus databases like HeinOnline. Some extend remote access to cardholders. If a question genuinely needs a paid platform’s citator or secondary sources, a trip to the law library often gets you there for free — and law librarians can point you to the right source.
The Limits of Free Research
Free tools are excellent for finding and reading primary law, and weaker at three things: telling you whether a case is still good law, surfacing curated secondary sources that explain a field, and covering state trial-court materials comprehensively. Knowing those gaps is what separates careful free research from risky free research. Use the free stack for most work, lean on library access for the citator step, and see our full legal research platforms overview to decide when a paid tool is worth it.
