A legal research engine over primary law
UpLaw indexes court opinions, statutes, regulations, court rules, public laws, and legislation from federal and state sources in one full-text index, cross-linked by the citations inside the documents. Searching is free; a subscription unlocks the premium library, directory data, and the research tools.
What you can search
- Federal and state court opinions, from the Supreme Court to the trial courts, with parallel citations resolved
- The United States Code by section, Public Laws, and the Federal Register
- State codes and administrative codes from dozens of states
- Federal court rules, sentencing guidelines, and bills in Congress and the state legislatures
- Dockets and filings, judges, attorneys, experts, and agency decisions
How a search works
Type a citation and you land on the document. Type a question or a phrase and you get ranked results with facets for type, jurisdiction, court, and year — the same query shaping (abbreviation expansion, citation detection) on every result. Every opinion page carries its treatment history, its citing cases, and the authorities it relies on.
Research tools on top of the index
- Ask UpLaw — a research question answered with citations to the documents the answer came from
- Brief Check — every citation in a brief extracted, resolved, and flagged
- Argument Builder — the authorities for a proposition, assembled
- Deep Research — an agentic research memo with verified citations, exportable to Word or PDF
Frequently asked questions
Is UpLaw free to use?
Searching the library and reading primary law is free. Paid plans add the premium practical library, directory data, and the AI research tools; see the pricing page for the current plans.
Where does the case law come from?
From public sources — the federal courts' own publications, the Caselaw Access Project, CourtListener, and law.resource.org — loaded into one index and de-duplicated so one case is one page.
Can I cite what I find here?
Every document page shows its citation, its source, and a link to the source record. UpLaw provides legal information, not legal advice; verify against the official reporter before filing.
