Online Case Management and Filing (ECF) and Reporting Tools (PACER)

The United States Court of Appeals for the Tenth Circuit provides two tools to enable online access to important court services and functions. The PACER system enables users to obtain, view, and print case records from federal Appellate, District, and Bankruptcy courts via the Internet. The ECF (aka CM/ECF) system is a comprehensive case management system that enables users to file electronically in cases pending before the United States Court of Appeals for the Tenth Circuit. As of May 15, 2017, the court upgraded its operating system to NextGen ECF. NextGen is accessible via the PACER system.

ECF became mandatory for all attorney filers on June 1, 2009. Please see the court's ECF User's Manual for information on registering for ECF and using ECF to file pleadings with the court. In addition, please see the link on the right side of this page to access the ECF system, including registration information, training tools and FAQs.

You may now submit petitions for writ of mandamus, petitions for review and Fed. R. App. P 5 petitions electronically using the utilities menu in CM/ECF. Please see the sections in the court's CM/ECF Users Manual for additional information regarding these options.
