Electronic Filing

Learn how to file case documents online.

Get Started with E-filing

As of May 1, 2021, the court began to process new petitions for review in immigration cases through the court’s new Appellate Case Management System (ACMS). Since then, other case types have been opened in ACMS, and as of October 1, 2023, all new cases opened in the U.S. Court of Appeals for the Ninth Circuit will be opened in ACMS.
Learn more about ACMS.

Cases opened in CM/ECF will continue to be processed via CM/ECF unless the Court directs otherwise.

E-file in our legacy system:

If you’re representing yourself, you can also submit case documents through the Court’s Electronic Document Submission System.

• CM/ECF and ACMS Case Numbers
  CM/ECF case numbers start with the year, followed by a hyphen, and a 5-digit number. ACMS case numbers for all cases opened in that system since May 1, 2021, start with the year, followed by a hyphen, and a number less than 5 digits.
  For example, 21-70002 is a CM/ECF case number; 21-20 is an ACMS case number.

Before you can e-file using ACMS, you'll need to set up an account in PACER

A PACER account lets you:

1. E-file with ACMS

2. Electronically view documents in a case

Set up an account in PACER:

• Set up your account as soon as possible to avoid delays in filing.
  ATTORNEYS: You must set up your account before you file your first documents.
  PRO-SE LITIGANTS: You are not required to file documents electronically, however, if you are not currently incarcerated, you may register after you have an open case (assigned a case number) in our Court.

Keep in mind

• Don’t share your PACER account log-in ID or password with anyone.

  You are responsible for making sure that you don’t incorrectly share sealed documents that you have access to. For instance, if you share your PACER log-in information with a third-party service provider, you’ve given them access to sealed case documents. That violates the rules, statutes, and/or orders of this Court.

  If you are a fee-exempt user of PACER, you can’t share the documents you get from ACMS. If you want to share them, you have to ask the court for permission.

• Keep your account information up-to-date.

If You're an attorney

You can register for PACER before you apply for the bar of this court. But, any attorney who files an appeal or enters an appearance in this Court (including counsel for amicus parties) should apply for admission to the bar at the same time.
