Search American law in the free archive run by the nonprofit Free Law Project. Search around ten million published court decisions, federal and state, and read any of them in full. Check every case citation in a piece of writing against the archive, which is how an invented citation is caught before it is filed. Follow federal litigation through the dockets collected out of PACER, from the case down to what was filed and when. Look up the judges who decide these cases and every seat they have held, and find recorded oral arguments with the audio. Free to use, with a free account.

Steps your workflow can run in CourtListener.

Check citationsFind every case citation in a piece of text and check each one against the archive. Paste in a brief, a memo, a contract or anything a language model wrote, and get back each citation it contains with a verdict: the real case it points to, or a plain statement that no such case exists. Citations with a typo in them are corrected where the correction is obvious. This is the step to put in front of anything that will be filed or sent, because an invented citation reads exactly like a real one until somebody looks it up.
Search case lawSearch around ten million published decisions of American courts, federal and state, going back to the eighteenth century. Search by words in the decisions, by the name of the case, by a citation, by the judge who wrote it, by the court it came from, or by when it was decided, and combine any of those. Each result carries the case, how to cite it, how often it has since been cited, and the separate opinions written in it, so a dissent can be read on its own. The twenty best matches come back, along with how many there are in all.
Get a caseRead the full record of one decided case: its name, the day it was decided, every way it can be cited, the judges who sat on it, how often it has been cited since, and whatever the court published alongside the decision such as the syllabus, the posture and the procedural history. It also lists the separate decisions written in the case, so the majority, a concurrence and a dissent can each be read in full with Get a decision. Takes the case ID that a case law search or a citation check returned.
Get a decisionRead the words of one decision in full: a majority opinion, a concurrence, a dissent or a per curiam order. The answer says which kind it is, who wrote it, which judges joined it, and which other decisions it cites, and carries the text itself with the markup taken off, ready to summarise, quote or search in a later step. Takes the decision ID that a case law search or Get a case returned.
Search federal casesSearch federal court cases, the live litigation rather than the decided case law: district court, appellate and bankruptcy dockets collected out of PACER by the RECAP archive. Search by words in the documents filed, by the name of the case, by its docket number, by a party or a law firm, by the judge it is assigned to, by what kind of suit it is, or by when it was filed. Each result carries the case, the judge, the parties, and the filings that matched. The twenty best matches come back, along with how many there are in all.
Get a federal caseRead the full record of one federal court case: its name and docket number, the court and the judge, when it was filed, when anything was last filed in it, whether it has been closed, what kind of suit it is, and what it was appealed from. It also points at the decisions published in the case and any recorded oral arguments, so the litigation and the case law it produced join up. Takes the case ID that a federal case search returned.
List filingsList what has been filed in a federal court case, newest or oldest first, with the date and the court's own description of each entry and the documents attached to it. Narrow it to a range of dates to see only what has happened lately, which is how a workflow watches a case it cares about. Each document says how many pages it runs to and whether the archive holds the document itself, and its text can be included when a later step needs to read it.
Search judgesSearch thousands of federal and state judges by name, by the court they have sat on, by where they studied, by who appointed them, by their political affiliation, or by how they came to the bench. Each result carries their dates, their schools, any American Bar Association rating, and every seat they have held with the dates. Use it to find out who will hear a matter before it is heard. The twenty best matches come back, along with how many there are in all.
Get a judgeRead one judge's biography and their whole career on and off the bench: every seat and job on record, when each started and ended, who appointed them, when they were nominated and confirmed, and why a seat ended. Takes the judge ID that a judge search returned, or the one carried on a decision as its author.
Search oral argumentsSearch recorded oral arguments from the Supreme Court and the federal appellate courts, by what was said, by the case, by its docket number, by the judges on the panel, by the court, or by when it was argued. Each result carries the date, how long the argument ran, and a link to the recording itself, so a later step can transcribe it or hand it to somebody to listen to. The twenty best matches come back, along with how many there are in all.
