AO 451: Clerk's Certification of a Judgment to be Registered in Another District
AO 451, Clerk's Certification of a Judgment to be Registered in Another District, is a one-page form from the U.S. Courts for a civil action in a United States District Court. The U.S. Courts page lists it under Civil Judgment Forms, effective on December 1, 2012, and the PDF prints the edition AO 451 (Rev. 12/12).
It is completed and signed by the court's clerk, not by a party. On it, the clerk certifies that the attached judgment is a copy of a judgment entered by the court on a stated date, and that, as appears from the court's records, no motion listed in Fed. R. App. P. 4(a)(4)(A) is pending, the time for appeal has expired, and no appeal has been filed or, if one was filed, it is no longer pending. The form has a date line and a signature line for the Clerk or Deputy Clerk under CLERK OF COURT.
This page explains the form in plain words and is not legal advice. You can fill it out free in your browser on this page and download the result without an account.
