Free legal citation checkerCheck every citation
before you file.
Paste a brief or drop the file. We find the case citations, statutes and quotations in it and check each one — without the document leaving your computer.
Your document. Read and parsed in this browser tab, and never uploaded.
Numbers only — 576 U.S. 644. You see the list first.
Nothing. No account, no sign-in.
We can tell you a case exists and whether a quotation is in it. We cannot tell you it is still good law, or that it supports what you wrote — no free source carries that, and we will not pretend otherwise.
Your document has not been sent anywhere and will not be. It was read and parsed in this tab. This is everything that leaves your computer:
Not the case names. Not your argument. Not a word of the text around them.
They go to CourtListener, run by the Free Law Project, a non-profit. They receive the list above and our server’s address — not yours. Nothing is logged here.
These are not being sent, because no reporter is abbreviated this way. Most often a typo; sometimes a citation that was never real. Either way the database cannot answer for them, so they are yours to check.
Found means the case exists. It does not mean the case is still good law, and it does not mean it supports what you wrote. Both of those are still yours to check. What we check against.
Checking a brief is one part of it. There is a workspace for a whole matter — your documents indexed on your own machine, every case an answer cites checked the same way this page checks them, and a model that can run in this browser so that nothing about the matter leaves it. Free, no account, and early.
