An electronic filing system for courts is the secure online platform a court uses to receive, timestamp, and docket legal documents. Instead of carrying paper to a clerk’s window, you upload a PDF through a web portal, the system records the moment it arrives, and the filing becomes part of the official record. Federal courts run a single nationwide platform called CM/ECF. Most state courts operate their own platforms, often through third-party vendors, with rules that vary by state and sometimes by county.
How Federal CM/ECF Works
Every federal court uses Case Management/Electronic Case Files, usually shortened to CM/ECF. It handles uploading motions and briefs, tracking case information, and generating the official docket.1United States Courts. Electronic Filing (CM/ECF) Attorneys, U.S. Trustees, and bankruptcy trustees are the primary users, and courts can grant access to others.
When a document is filed, CM/ECF creates a permanent, time-stamped docket entry and sends a Notice of Electronic Filing by email to every registered attorney in the case, with a link to the document.2U.S. Courts. FAQs: Case Management / Electronic Case Files (CM/ECF) That notice is proof of service on parties already in the case and proof that the court received the filing. It carries a unique verification code and the timestamp that becomes the legal filing date.
Under Federal Rule of Civil Procedure 5, a filing made through a person’s electronic filing account, authorized by that person and bearing their name on a signature block, counts as that person’s signature, and an electronically filed paper is treated the same as a written paper for all purposes under the rules.3Legal Information Institute.

Viewing Filed Documents Through PACER
PACER, the Public Access to Court Electronic Records system, is the public-facing side of federal e-filing. With a PACER account you can search dockets, orders, and filed documents in any federal appellate, district, or bankruptcy case, around the clock.1United States Courts. Electronic Filing (CM/ECF)
Access costs $0.10 per page, capped at $3.00 for a single document, which works out to the equivalent of 30 pages no matter how long the filing runs.4PACER: Federal Court Records. PACER Pricing: How Fees Work The cap does not apply to search results, non-case-specific reports, or transcripts, which stay at $0.10 per page without a maximum.5United States Courts. Electronic Public Access Fee Schedule
Several categories are free. Judicial opinions carry no charge. Viewing records at a public-access terminal inside a courthouse is free. Parties and their attorneys of record also get one free electronic copy of every document filed in their case through the Notice of Electronic Filing.5United States Courts. Electronic Public Access Fee Schedule Courts can also exempt certain users, including indigent parties, pro bono attorneys, and nonprofit organizations.6PACER: Federal Court Records. Frequently Asked Questions
State Court E-Filing
Most state courts have their own electronic filing platforms, and the technology and rules vary widely. Unlike CM/ECF, which is one platform nationwide, many states contract with third-party vendors. Some states mandate e-filing for all case types, others require it only in certain courts or for certain categories, and a few still treat it as optional.
The practical differences matter. State systems often add a small convenience fee on top of the court’s filing fee. Accepted file formats, size limits, and payment methods can differ from county to county within the same state. If you are filing in state court for the first time, read that specific court’s e-filing page before you start.
Filing Fees
Opening a new civil case in federal district court costs $405.7Office of the Law Revision Counsel. 28 USC 1914 – District Court; Filing and Miscellaneous Fees; Rules of Court A habeas corpus petition carries a much lower statutory fee of $5. Appellate filing fees are set separately and differ by court level.
Payment usually happens during the filing itself through an integrated gateway like Pay.gov. If a required fee is not paid, the filing can be rejected, so a current payment method matters more than it might seem. In some courts an expired credit card on file has been enough to cause a filing to fail even though the document uploaded successfully.
Document Format and Size Rules
Electronic filing systems are strict about format, and a rejected filing does not pause your deadline. Federal courts require submissions in PDF or PDF/A format, which preserves formatting and prevents alteration after upload.8Supreme Court of the United States. Guidelines for the Submission of Documents to the Supreme Court’s Electronic Filing System PDF/A is the archival version and is preferred by many courts because it embeds fonts and disables features that could degrade over time.
File size limits vary significantly. Some district courts cap individual files at 10 megabytes, others allow 35 to 60 megabytes, and the Supreme Court permits files up to 100 megabytes.8Supreme Court of the United States. Guidelines for the Submission of Documents to the Supreme Court’s Electronic Filing System If a document exceeds the limit, split it into separate files. The system will not partially accept an oversized upload. It simply fails.
Redacting Personal Information Before You File
Because electronically filed documents end up in a database the public can search through PACER, Federal Rule of Civil Procedure 5.2 limits what can appear in a filing:9Legal Information Institute. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection For Filings Made with the Court
- Social Security and taxpayer ID numbers: last four digits only.
- Financial account numbers: last four digits only.
- Dates of birth: year only.
- Names of minors: initials only.
Responsibility falls on the filer. Court clerks are not required to review documents for compliance, and a filing with unredacted personal data becomes part of the public record the moment it hits the docket. If a filing needs to include the full, unredacted information, the court can order it filed under seal, or the filer can submit a redacted version for the public record alongside an unredacted copy under seal.9Legal Information Institute. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection For Filings Made with the Court The court can also impose additional restrictions for good cause, including limiting remote electronic access by nonparties.
Deadlines and What Happens If the System Goes Down
For electronic filings in federal court, the deadline is midnight in the court’s time zone unless a local rule or court order sets an earlier cutoff.10Legal Information Institute. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time; Time for Motion Papers A lawyer in California filing in a New York court loses three hours if they are thinking in Pacific time. Some courts set tighter windows, with deadlines as early as 6:00 p.m. local time for certain filings.
When the court’s filing system goes down, the rules provide a safety net. If the clerk’s office is inaccessible on the last day for filing, the deadline extends to the first accessible day that is not a weekend or legal holiday. If the system goes down during the last hour of the deadline, the deadline extends to the same time on the next accessible day.10Legal Information Institute. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time; Time for Motion Papers The rule’s advisory notes confirm that “inaccessibility” includes electronic system outages, not only physical closures.
If the problem is on your end, the deadline does not move. Your internet going out, your PDF software crashing, or your payment method being declined are your problems. Build in a buffer of a few hours before any filing deadline.
What E-Filing Does Not Do
The Notice of Electronic Filing that CM/ECF generates serves as proof that parties already in the case received the document. It does not satisfy the requirements for initial service of a lawsuit. The original complaint and summons must still be served on the defendant through the methods described in Federal Rule of Civil Procedure 4, including personal delivery, leaving copies at a dwelling, or serving an authorized agent.3Legal Information Institute. Federal Rules of Civil Procedure Rule 5 – Serving and Filing Pleadings and Other Papers Only after the defendant has appeared does electronic service through CM/ECF become the standard method for later filings.
Access for Self-Represented Filers
Attorneys admitted to practice before a federal court generally receive CM/ECF filing access as part of bar registration. The path for self-represented (pro se) litigants is different. In most federal courts, a pro se party must file a formal motion asking the presiding judge for permission to use the electronic filing system.11Federal Judicial Center. Federal Courts’ Electronic Filing by Pro Se Litigants Some courts handle it at the clerk’s office level with a less formal application, but the basic requirement is the same: you need permission first.
Practical requirements include an email address, the ability to create PDF documents, and a PACER account. Courts evaluating a pro se request typically want to see technical capability to comply with the filing rules, and they tend to deny e-filing privileges to litigants with a history of abusive or frivolous filings.11Federal Judicial Center. Federal Courts’ Electronic Filing by Pro Se Litigants If the court denies the motion, the pro se party files on paper and may still be able to receive electronic notifications of other filings by email.
