General Attorney Information

Attorneys seeking to practice before the U.S. District Court for the District of Colorado must become members of the bar by completing an Application for Admission to the Bar of the Court (“Application”). The Court does not accept pro hac vice applications. Eligibility is limited to persons licensed by the highest court of a state, federal territory or the District of Columbia, who are on active status, and in good standing in all courts and jurisdictions where admitted. There are no yearly dues or continuing legal education requirements, and an attorney’s membership is valid unless and until terminated by the Court. An attorney need not be a member of the Colorado bar or associated with local counsel to practice here.

All applications for admission to the Court's Bar must be submitted by completion of an electronic form, through the Court’s Attorney Services Portal on the Court’s website. Registration for the Court’s Case Management/Electronic Case Filing System (CM/ECF) can be completed simultaneously, allowing for speedy access to the Court’s filing system for new and existing attorneys. A link to the Portal is provided below and requires creation of an individual online account for all attorneys. You may also submit an online application through the Attorney Services Portal, by visiting the Clerk’s Office in the Alfred A. Arraj Courthouse, 901 19th St., Denver Colorado, 80294.  Completion of the form must be accompanied by a $223.00 fee, paid online from a bank account or by credit/debit card through, a service of the U.S. Department of the Treasury.

The online application form ensures the accuracy of attorney contact information and also allows attorneys to perform a variety of functions – they may register for the Electronic Case Filing System, change their contact information, and order certificates of good standing or duplicate bar admission certificates.  The Court will issue a downloadable Certificate of Admission after successful completion of the online application form and review by Court staff of the online admission form, and the applicant will receive an e-mail confirmation.
