AO 445: Warrant for the Arrest of a Witness in a Civil Case
AO 445, Warrant for the Arrest of a Witness in a Civil Case, is a United States District Court form from the U.S. Courts. The U.S. Courts page lists it under Civil Forms, effective on November 1, 2011. The PDF prints the edition AO 445 (Rev. 11/11) and titles it Warrant for the Arrest of a Witness in a Civil Action.
It is a warrant the court issues in a case captioned Plaintiff v. Defendant with a Civil Action No. Page 1 is addressed "To: Any authorized law enforcement officer," commands the arrest of a witness who was served with a subpoena to appear and failed to do so, and is signed by the Clerk or a Deputy Clerk. It ends with a Return the arresting officer completes. Page 2 holds the witness's personal identifiers and is marked Not for Public Disclosure. It is not a form a member of the public completes.
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.

Questions about Form AO 445
Who signs AO 445?
The Clerk or a Deputy Clerk, in the CLERK OF COURT block on page 1. The arresting officer later signs the Return. It is not a form a member of the public completes.
Which witness does AO 445 cover?
The form describes a witness who has been served with a subpoena to appear in the civil action and has failed to do so.
Is it a civil case or a civil action form?
Both names refer to AO 445. The U.S. Courts page calls it Warrant for the Arrest of a Witness in a Civil Case, and the PDF prints Warrant for the Arrest of a Witness in a Civil Action.
What does the warrant say happens after the arrest?
It commands the officer to bring the person before the court and to detain the witness until the court orders discharge from custody. The arresting officer then completes the Return.
Why is page 2 marked Not for Public Disclosure?
The form says page 2 contains personal identifiers provided for law-enforcement use only and therefore should not be filed in court with the executed warrant unless under seal.
Is this page legal advice?
No. This page explains the form in plain words and is not legal advice. It does not say whether a warrant is valid or what a witness can do about one.
