Cite11

Citation verification for legal briefs

Catch it before the judge does.

Upload a filing and get a dated Verification Report: every case citation checked against the public case-law record, wrong reporters and pages corrected, and citations to cases that do not exist flagged — before opposing counsel or the court finds them.

In Mata v. Avianca (S.D.N.Y. 2023), six of the cases cited in a filing did not exist. The court found out.

Your filing is checked against the public court record and is not retained by Cite11. Only the citations found in it are sent to CourtListener; see Privacy.

Works best on briefs, motions, and opinions that argue from case law — a complaint or answer usually has no case citations to check.

Checking a single citation? Try the free lookup instead.

What you get

  • Every citation checked against the record. Not only whether the citation number exists, but whether it leads to the case named — a real address can belong to a different case.
  • Corrections, not just flags. When a citation is close but wrong — the right case at the wrong reporter or page — the correct citation is offered.
  • A report for the file. A dated Verification Report with its own report id, returned to you as a page you can copy or print; neither your filing nor the report is retained by Cite11.
  • Quotations and dockets checked. A quotation next to a citation is compared with the opinion text, and a case cited only by docket number is checked on its docket. Nothing in the report is written by AI: the Summary is generated from the results by fixed rules.

How it works

  1. Upload the filing

    A PDF or plain-text brief, up to 10MB. It is read once for its citations and not kept.

  2. Each citation is checked against the record

    Name, address, and court and year — every case citation, against the public case-law record — and the quotation attributed to it. Anything that could not be checked is listed as not checked, with the reason, never guessed at.

  3. You get a Verification Report

    Dated, with its own report id: each citation verified, case confirmed, belonging to a different case, not confirmed or not found, and a plain statement of what was and was not checked. Copy or print it for your records — it is not stored by Cite11 after the check completes.
