NOTICE: A phone scam is targeting people in custody and their families. Callers pretend to be employees of the U.S. Probation Office, U.S. Parole Commission, and Federal Bureau of Prisons (BOP). Their goal is to obtain money and personal information. Callers have promised to get individuals out of BOP custody, end supervised release, and approve relocation requests.

U.S. probation officers and staff from other federal agencies do not ask for money in exchange for services. Please report these calls to the Federal Trade Commission online or by phone at 1 (877) 382-4357 (9:00 a.m. to 8:00 p.m.).

Procedures for Access and Management of Sealed and Restricted Documents

On September 24, 2025, Chief Judge Brimmer entered General Order 2025-2 regarding procedures for access and management of sealed and restricted documents (hereinafter referred to as "sealed documents"). Effective immediately, sealed documents will continue to be filed in CM/ECF under existing procedures but will no longer be accessible or viewable by electronic means. Because sealed documents filed in CM/ECF will no longer be accessible or viewable electronically, service cannot be accomplished through CM/ECF. Instead, parties will have to serve sealed documents by other appropriate means as provided by the Federal Rules of Procedure. The Court (and Probation Office) will serve sealed documents in paper by US mail. A party with the right to access a sealed document in a case who requires a copy of a sealed document must contact the Clerk's Office or Probation Office. Requests for paper copies of sealed documents will be subject to the current docket copy fee rate. For more information and a copy of the General Order please click here.
Any questions about the filing of and access to sealed documents should be directed to the Clerk's Office at 303-844-3433, or the Probation Office at 303-844-5424.
