PACER and CM/ECF work together. This court is using NextGen CM/ECF and requires an updated PACER account that also allows users to file in this court. All Federal Appellate courts are also using NextGen and over time, all District and Bankruptcy Courts will as well. If permitted, you can apply for filing permissions at other courts using the same upgraded PACER login. Please contact the PACER service center if you have questions. https://www.pacer.gov/contact.html
If you are permitted to file in another Federal court that is not using NextGen yet, you need to contact that court directly for a CM/ECF filing account.
