An electronic filing system is a secure online portal that lets you submit legal documents to a court over the internet instead of walking paper copies to the clerk’s window. In the federal courts, the platform is called Case Management/Electronic Case Files, or CM/ECF, and it handles motions, petitions, exhibits, and nearly every other filing across federal district, bankruptcy, and appellate courts.1United States Courts. Electronic Filing (CM/ECF) Most state courts run comparable systems, often through third-party vendors. You log in through a browser, upload PDFs to the correct case, pay any required fees, and receive a time-stamped confirmation that the court has your document.
How the System Works
The portal is a web application sitting on top of the court’s case database. Encrypted connections carry the data from your browser to the court’s servers, where filings are stored with different access levels depending on whether they are public or restricted. When you upload a document, you tell the system which case it belongs to and what kind of document it is. The system routes it to the right place on the docket, logs the date and time of receipt, and sends automatic notifications to every other registered party in the case.
Who Has to File Electronically
If an attorney represents you in federal court, electronic filing is mandatory. Federal Rule of Civil Procedure 5(d)(3)(A) requires anyone represented by counsel to file electronically unless the court grants an exception for good cause or a local rule provides otherwise.2Cornell Law School. Federal Rules of Civil Procedure Rule 5 – Serving and Filing Pleadings and Other Papers
Self-represented litigants face a different setup. More than half of federal district courts allow pro se filers to use CM/ECF only with individual permission, usually granted by motion to the presiding judge. Even where it is permitted, pro se access is typically limited to cases already open, not new filings that would start a lawsuit. Courts running the NextGen version of CM/ECF require pro se filers to create a PACER account first, which the court then links to filing privileges. Some courts also screen applicants and deny access to filers with a history of abusive litigation.3Federal Judicial Center. Federal Courts Electronic Filing by Pro Se Litigants
Registering for an Account
Before filing anything, you create an account on the court’s portal. Registration asks for your full legal name, mailing address, and an email address that will become the channel for every future case notification, including court orders and filings from the other side. Attorneys supply a bar number and the jurisdiction where they are admitted, and the system may verify this before granting filing access.
You also link a payment method, typically a credit card or bank account, so filing fees can be charged at the moment of submission. Fees vary with the type of case and the court. After the profile is complete, the system can auto-populate document headers and docket entries on later filings, which cuts down on repetitive data entry.
Preparing Your Documents
Every document must be in Portable Document Format (PDF), because PDF preserves the layout no matter what device the judge or clerk uses to open it. Most courts also require the PDF to be text-searchable, meaning it contains real text rather than a scanned image of a page. If you scan a paper document, run optical character recognition on it before uploading.
Each court sets its own cap on PDF file size. Some limit individual files to 25 megabytes; others allow up to 50 megabytes.4PACER. Is There a Limit on the Size of PDF Files Which CM/ECF Will Accept? If a filing is too large, split it into separate smaller documents rather than compressing the quality.
Redacting Personal Information
Federal Rule of Civil Procedure 5.2 limits what personal information can appear on the public docket. When a filing contains a Social Security number, taxpayer identification number, birth date, a minor’s name, or a financial account number, you may include only the last four digits of the Social Security or taxpayer ID number, the birth year, the minor’s initials, and the last four digits of any financial account number. The responsibility to redact is entirely yours. The clerk’s office does not screen for compliance, and anything you fail to redact becomes publicly accessible online. You can ask the court for relief if you file an unredacted identifier by mistake, but the damage may already be done.5Cornell Law School. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection for Filings Made with the Court Also strip hidden metadata, such as revision history and author comments, from the PDF before uploading.
Electronic Signatures
A handwritten signature is not required. In federal courts, the convention on the signature line is to type “/s/” followed by your name (for example, “/s/ Jane Smith”). Filing a document under your CM/ECF login counts as your signature for purposes of the Federal Rules of Civil Procedure. When a document needs signatures from multiple parties, such as a joint stipulation, the filing attorney gathers the other signatures beforehand and represents on the document that each party authorized it.
Submitting the Filing and Paying Fees
Once the documents are ready, you log in, either pull up an existing case by number or start a new case through the menu, and select the document type that matches what you are filing. Choosing the right category matters because it tells the system how to label and route the filing on the docket.
After attaching the PDFs and confirming the descriptions, the system shows a review screen with the total fees. Your linked payment method is charged when you hit the final submit button, and the court’s server logs the filing immediately. Most portals show a progress indicator during the upload so you can confirm the transfer finished without interruption.
In many state court systems, a third-party filing service provider handles the submission rather than the court itself. These vendors often add a per-transaction convenience fee on top of the court’s statutory filing fee, so budget for both.
Your Confirmation and Automatic Service on Other Parties
A successful submission produces a Notice of Electronic Filing (NEF), the court’s official confirmation that your document was received. The NEF records the exact date and time of entry and includes a unique identification number tying the document to the docket.1United States Courts. Electronic Filing (CM/ECF) Save a copy. This time-stamped receipt is often your only proof that you met a deadline.
The NEF also serves as automatic notice to every other registered party in the case. Under Federal Rule of Civil Procedure 5(b)(2)(E), filing through the court’s system counts as legal service on all registered users, so you do not need to separately email or mail copies to opposing counsel who are registered on CM/ECF, and no certificate of service is required. If you need to serve someone who is not a registered user by other electronic means, such as direct email, that person must have consented to electronic service in writing.2Cornell Law School. Federal Rules of Civil Procedure Rule 5 – Serving and Filing Pleadings and Other Papers
Some judges still require courtesy paper copies of certain filings, particularly complex motions, delivered to chambers after you file electronically. Check your judge’s individual practices or standing orders.
Deadlines and System Outages
Electronic filing deadlines in federal court run on the court’s local time zone, not yours. A midnight deadline means midnight where the court sits.6Cornell Law School. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time A West Coast filer facing an Eastern Time court deadline loses three hours; an East Coast filer facing a Pacific Time court gains them.
When the court’s own electronic filing system goes down and becomes inaccessible, Federal Rule of Civil Procedure 6(a)(3) extends your deadline to the next day the system is available, as long as that day is not a weekend or legal holiday.6Cornell Law School. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time The advisory committee notes confirm that a system-wide outage qualifies as the clerk’s office being inaccessible. If the outage occurs only in the last hour before your deadline, the extension runs to the same time on the next accessible day.
A problem on your end, such as a dead internet connection or a crashing browser, is treated differently. Document the error with screenshots, contact the clerk’s office as soon as possible, and file a declaration explaining what happened once you have access again. Many courts require that declaration by the close of the next business day. If the deadline is critical, ask the clerk whether you can submit on paper as a backup.
Fixing Filing Mistakes
Attached the wrong PDF? Picked the wrong case number? Chose the wrong document type? Courts generally expect you to fix these yourself rather than wait for the clerk to catch it. Refile the corrected document in the proper case and notify the clerk’s office, usually by email, with the case number, the docket number of the incorrect entry, and a short explanation.
If the problem was the wrong attachment, file the right one and reference the docket number of the erroneous entry so the clerk can link the two. Do not assume the clerk will automatically pull the bad filing off the docket. Follow up.
Clerks commonly reject filings before they reach the docket for selecting the wrong jurisdiction, uploading a PDF that is not text-searchable, combining documents that should have been filed separately, or submitting with a declined payment method. A rejected filing never hits the docket and does not satisfy a deadline, so check your email for rejection notices right after submitting.
Sealed Filings and What Cannot Be Filed Electronically
Most documents go on the public docket, but some require restricted access. To file under seal, you typically first submit a motion explaining why the court should seal the document, and that motion itself is public. Do not attach the confidential material to the motion or spell out the sensitive details in the motion’s text. Once the court grants permission, you file the sealed document under a separate event category that automatically restricts public access.
A narrow set of documents, called Highly Sensitive Documents, cannot be filed electronically at all. These include materials tied to national security investigations, certain cyber investigations, and documents containing trade secrets or source code whose disclosure could have significant consequences. Courts require them delivered on paper or on a secure physical device such as a USB drive, bypassing the electronic system entirely.
Viewing Filed Documents
Once a document is on the docket, authorized parties can view and download it through the portal. Broader public access to federal court records runs through PACER (Public Access to Court Electronic Records), which charges $0.10 per page with a cap of $3.00 per document.7United States Courts. Electronic Public Access Fee Schedule If your PACER charges stay at $30.00 or less in a quarter, the fees are waived.8PACER. PACER Pricing: How Fees Work Sealed documents, juvenile records, and other confidential materials remain restricted to authorized parties regardless of PACER access.
