A legal cases search engine lets you look up court opinions, dockets, and filings online without a lawyer or a trip to the courthouse. Three tools cover most of what a non-specialist needs: Google Scholar for published judicial opinions, CourtListener for opinions plus a large free archive of federal court filings, and PACER for the official federal docket system. Which one you reach for depends on whether you want a judge’s written ruling, the full case file, or records from a specific state court.
Google Scholar for Court Opinions
Google Scholar is the easiest free starting point for finding judicial opinions. It covers published opinions from state appellate and supreme courts going back to 1950, federal district and appellate courts since 1923, and U.S. Supreme Court decisions since 1791.1Google. Google Scholar Search Help Click “Case law” under the search bar, then “Select courts” to narrow results to specific jurisdictions.2Georgetown Law Library. Free Sources of Case Law – Free and Low Cost Legal Research Guide
Scholar is strong for appellate opinions and for checking which later cases cited a ruling. It does not include dockets, motions, briefs, or trial court filings. If you need the paperwork behind an opinion, you’ll need to go elsewhere.
CourtListener and the RECAP Archive
CourtListener, run by the nonprofit Free Law Project, is the strongest genuinely free alternative. It holds millions of opinions from federal and state courts, and its RECAP Archive contains tens of millions of federal court documents that were originally purchased through PACER.3Free Law Project. RECAP Suite — Turning PACER Around Since 2009 When someone downloads a PACER document through the RECAP browser extension, a copy goes into the archive, where you can pull it at no cost. The archive is fully searchable, including documents that were originally scanned PDFs.
Before paying for anything on PACER, check CourtListener first. The filing you want may already be there.
Other free sources are worth knowing about. Justia carries a large volume of federal and state case law and statutes. The Caselaw Access Project at Harvard Law Library digitized all official book-published U.S. case law. Cornell’s Legal Information Institute covers Supreme Court cases, selected historic decisions, and federal statutes and rules.4New York Law School. Free and Low Cost Legal Research – Case Law – General Sources One name you’ll see in older guides is Casetext; Thomson Reuters acquired it in 2023, and it is now a paid professional product rather than a free tool.5Thomson Reuters. Thomson Reuters Completes Acquisition of Casetext, Inc.
PACER for Federal Case Files
The Public Access to Court Electronic Records system, known as PACER, is the official gateway to federal court filings. It covers appellate, district, and bankruptcy courts and includes dockets, motions, briefs, orders, and opinions. Unlike Google Scholar, PACER gives you the actual case file rather than just the judge’s published opinion.
Registration is free, but you need an account before you can search.6PACER. Case Search Only Providing a credit card during registration gives you immediate access. Without one, an activation code arrives by mail in seven to ten business days. Once logged in, the PACER Case Locator searches a nationwide index, updated daily, across all federal courts at once instead of forcing you to hunt through individual court websites.7PACER. Find a Case
PACER charges $0.10 per page for documents, capped at the cost of 30 pages per document. If your total charges stay at $30 or less during a quarterly billing cycle, the fees are waived entirely.8United States Courts. Electronic Public Access Fee Schedule That waiver covers a lot of casual research.
Searching State and Local Court Records
State courts handle most litigation in the country, including civil disputes, criminal cases, and family law. Most states run their own electronic filing and search portals, but the infrastructure varies dramatically. Some states operate a single statewide system; others leave it to individual counties. A few still have limited or no online access.
Finding a state case requires knowing both the state and the specific court level. Trial courts, appellate courts, and supreme courts usually maintain separate records. Some portals offer free access to basic case information like party names, filing dates, and case status, then charge for full document downloads. There is no single national directory covering every state court system, so the practical approach is to search for the specific court’s website by name.
Information You Need Before Searching
The more identifying information you have, the faster you’ll find what you want. Party names are the common starting point: the full legal names of plaintiff and defendant as they appear on court documents. Slight spelling variations will make a search miss, so try alternates if your first try comes up empty.
A case number takes you straight to the file. Federal case numbers follow a standard format with a division code, year of filing, a case type abbreviation, and a sequence number.9United States District Court. The Courts Case Numbering System CV means a civil action, CR means criminal, and BK means bankruptcy.10Loyola Law School. Docket Numbers So 2:23-cv-01234 was filed in division 2, in 2023, as a civil case, and was the 1,234th filing that year. Judge initials sometimes appear at the end and can usually be dropped when searching.
Legal citations are the other precise identifier. A citation like 410 U.S. 113 points to volume 410 of the United States Reports, starting at page 113.11Legal Information Institute. Jane ROE, et al., Appellants, v. Henry WADE Citations work across every legal search platform and are how judges and lawyers reference prior decisions.
What a Case File Contains
The docket is the backbone of any case file. It’s a chronological log of every filing, motion, hearing, and order from the day the case was opened.12Library of Congress. Dockets and Court Filings – Legal Research: A Guide to Case Law Reading a docket shows you the full progression of a dispute: who filed what, when hearings happened, and how the judge ruled at each stage.
Within that docket, the most sought-after documents are judicial opinions, which contain the judge’s reasoning and legal conclusions. You’ll also typically find attorney briefs laying out each side’s legal arguments, motions requesting specific actions from the court, and final orders resolving the dispute.13UCI Law Research Guides. Dockets and Pleadings Trial exhibits and evidence presented in court also become part of the record and are generally accessible to the public. Courts have recognized a strong presumption that material introduced at trial should be available for public review, and documents previously covered by a protective order can lose that protection once used as exhibits in open court.14Reporters Committee for Freedom of the Press. E. Trial Records
What You Won’t Find Online
Not everything is in a searchable database, and knowing the gaps keeps you from assuming a clean search means a clean record.
Court transcripts, the word-for-word record of hearings and trials, are almost never included in online dockets. A court reporter prepares them only when someone orders and pays for one. In federal court, ordinary transcript rates start at $4.40 per page with a 30-day turnaround and run up to $8.70 per page for two-hour rush delivery.15United States Courts. Federal Court Reporting Program A full trial transcript can run hundreds of pages.
Cases filed before roughly 1999 are mostly in paper and may not appear in any online system. Older files are stored at the courthouse where the case was filed or have been transferred to the National Archives and Records Administration, and some have been destroyed under approved retention schedules.16United States Courts. Accessing Court Documents – Journalists Guide For a case from that era, start with the clerk’s office at the court where it was filed.
Settlement terms are another blind spot. When parties settle privately, the terms almost never appear on the public docket. You might see a filing noting the case was “dismissed with prejudice” or “settled,” but the dollar amount and conditions stay confidential. Most private arbitration proceedings and awards don’t appear in court databases at all, since they happen outside the court system. One exception is FINRA, which maintains a free public database of securities arbitration awards.17FINRA. Arbitration Awards Online
Sealed Records and Redactions
Federal Rule of Civil Procedure 5.2 requires that certain personal information be redacted from court filings. Social security numbers are limited to the last four digits, birth dates show only the year, minors are identified by initials only, and financial account numbers are truncated.18Legal Information Institute. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection For Filings Made with the Court These rules apply to both electronic and paper filings.
Some records are sealed entirely, meaning they won’t appear in search results or their contents are inaccessible without a court order. Juvenile criminal records are routinely sealed, and courts may seal cases involving trade secrets, certain family law matters, or sensitive law enforcement information. A sealed record is effectively invisible to public search tools, so an empty search result doesn’t necessarily mean no case exists.
Checking Whether a Case Is Still Good Law
Finding an opinion is only half the job. A ruling that was overturned on appeal or contradicted by a later decision can mislead you badly. Legal researchers use a process informally called “Shepardizing” (after an old print reference) to trace a decision’s later history and see whether courts upheld, distinguished, or reversed it.
The professional tools for this, Shepard’s on Lexis and KeyCite on Westlaw, are paid subscriptions aimed at lawyers. Google Scholar offers a partial substitute: each opinion shows a “Cited by” count linking to later cases that reference the decision.19Temple University Libraries. Free and Low-Cost US Legal Research Tools The count shows how often a case has been cited but doesn’t flag whether the treatment was positive or critical. If you’re relying on a case for anything that matters, reading the most recent citing opinions is the minimum due diligence available with free tools.
When You Need an Official or Certified Copy
A document downloaded from PACER or a state portal is an informational copy. It works for research but isn’t necessarily accepted for official purposes like proving a name change or confirming a judgment in another jurisdiction. For a document that carries legal weight, request a certified copy from the clerk of court. A certified copy includes a court seal or stamp verifying it as an authentic reproduction of the official record.
The process is straightforward: contact the clerk’s office at the court that handled the case, identify the document you need, and pay the certification fee. Fees vary by jurisdiction but typically run between $12 and $50 per document, with additional per-page charges for physical copies. Some courts handle requests online; others require an in-person visit or a written request by mail. For sealed or confidential records, additional paperwork or a court order may be required before the clerk can release a certified copy.
