The court’s words

“Any attorney who signs a filing for which an AI tool was used to prepare (including by appearing on the signature block of the filing) must attach to the filing a signed certification (i) stating whether the litigant personally reviewed the filing for accuracy of cited legal authorities and factual assertions and (ii) if so, describing in detail the steps taken to verify the accuracy of all legal authorities and factual assertions generated by the AI tool.”

Quoted from the court’s own document, read on 26 September 2026. Read it at the source.

What it asks of the person who signs

  • Certify that it was checked

    in the filing: that the content and the citations were verified.

  • Describe the steps taken

    how the citations were verified.

Applies to: Any filing an AI tool was used to prepare, by every attorney who signs it. Where it goes: A signed certification attached to the filing.

The statement, if one is called for

The order asks for words of its own. With the blanks filled in from your answers, they read:

CERTIFICATION REGARDING THE USE OF AN AI TOOL

An AI tool ([name the AI tool]) was used to prepare this filing.

(i) I [did / did not] personally review this filing for accuracy of the cited legal authorities and factual assertions.

(ii) The steps taken to verify the accuracy of all legal authorities and factual assertions generated by the AI tool: [how the citations were checked] [Describe how each factual assertion was verified against the record.]

On the check page Loupe drafts the statement for this court from the parts you tick, for you to read and sign: what it says is your choice and your responsibility. The order in force on the day is what counts; read it at the source before relying on this page.

Check the filing first

Paste the brief or drop the file, and Loupe looks up every citation in the published record: whether the case exists, whether it is the case the filing names, whether the pin cite falls inside the opinion; statutes, regulations, court rules and links too. It doesn’t generate anything, and what it can’t settle it marks “not verified”, never clean.
