AO 106A: Application for a Warrant by Telephone or Other Reliable Electronic Means

AO 106A, Application for a Warrant by Telephone or Other Reliable Electronic Means, is a United States District Court form from the U.S. Courts. The U.S. Courts page lists it under Law Enforcement, Grand Jury, and Prosecution Forms, effective on August 1, 2018, and the PDF prints the edition AO 106A (08/18).

The form is written in the words of a federal law enforcement officer or an attorney for the government, who requests a search warrant and states under penalty of perjury which person or property is to be searched, what is concealed there, the basis for the search under Fed. R. Crim. P. 41(c), the code sections involved and the facts. Instead of a line sworn in the judge's presence, it closes with an attestation "in accordance with the requirements of Fed. R. Crim. P. 4.1" by a reliable electronic means the form asks to specify, and a judge's signature. 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.
