Electronic Case Filing (CM/ECF)

Upgrade to NextGen CM/ECF on August 2, 2021. For more information regarding this upgrade click HERE.


The United States District Court, District of Colorado welcomes you to electronic case filing. Electronic case filing has two components, an electronic document filing component known as Case Management/Electronic Case Filing (CM/ECF), and an electronic document viewing component known as Public Access to Court Electronic Records (PACER). Both components may be accessed from the same login screen. Using CM/ECF for electronic filing has been mandatory in our court for civil cases since June 20, 2005 and for criminal cases since December 5, 2005. CM/ECF allows registered users to file electronically and receive email notice of filed documents. With exceptions for periodic maintenance, CM/ECF is available 24 hours a day, 7 days a week. PACER allows registered users access to case and docket information online from federal appellate, district, and bankruptcy courts.

To view electronic documents, a user must register and receive a login from the PACER Service Center. To file documents electronically using CM/ECF, a registered PACER user must also register with the court as a CM/ECF user. A PACER user does not have to register as an CM/ECF user to take advantage of conveniently viewing documents electronically, but will not be able to electronically file with a PACER login.
