Check that every case you cite exists.
Paste a brief or a list of citations. Each case is looked up in the public court record and checked against the name, year and court you cited, and each quotation is looked for in the opinion, on the page you cite.
Free. No account. Nothing is kept.
Questions.
What does it check?
Each full case citation in what you paste: whether an opinion is on the public court record at that volume, reporter and page, and whether its name, year and court match what the citation says. Statutes, rules and short forms like id. are not looked up.
How are quotations checked?
A quotation followed by a case citation, in quotation marks or as a block quotation, is looked for in the text of that case's opinion. Omissions marked with an ellipsis and changes marked with brackets are allowed for. You see whether the words are there, whether they are on the page you cite, and the opinion's own words where yours differ.
What does “could not confirm” mean?
That nothing is on record at that citation in the data we hold. It is a reason to pull the case before you file, not proof that it doesn't exist: recent decisions take months to reach the public record, many unpublished orders never get a reporter citation, and Westlaw and Lexis numbers are mostly absent.
What does “found, but not as cited” mean?
There is an opinion at that citation, and it is a different case, or the same case decided in a different year or by a different court. A mistyped page number lands on a neighbouring opinion this way, and so does a citation borrowed from a real reporter for a case that was never decided.
Where does the record come from?
CourtListener's public bulk data, published by the Free Law Project and refreshed every quarter. The lookup runs on our own server; your text is not sent anywhere else.
Do you keep what I paste?
No. The text is read in memory and gone when the answer is sent. It is not stored, logged or used for anything else.
Does it use AI?
No. Every case is looked up by its citation in a database of court opinions, so the same text always gets the same answer, and every “found” links to the opinion it found.
