Electronic Signatures for Federal Court Filing

Every document you file in federal court must be signed. For electronic filing through CM/ECF, that means typing /s/ Your Name on the signature line — not scanning your handwritten signature, not using DocuSign, not inserting a signature image. Here's exactly how to do it and what your signature actually commits you to.

The /s/ Format

Federal courts use a simple text-based signature format for electronically filed documents. On the signature line of your filing, type /s/ followed by your full legal name. That's it. No cursive fonts, no scanned images, no digital certificates.

The /s/ format is accepted by every federal court that allows electronic filing. The PACER help documentation confirms that electronic filing constitutes a signature for purposes of the Federal Rules of Civil Procedure. When you submit a document through CM/ECF, the act of filing — using your authenticated login credentials — serves as your signature under the court's local rules.

What Goes in the Signature Block

Below your /s/ signature, include a signature block with the following information. This block appears at the end of every document you file.

Your full legal name — typed out in plain text, matching exactly how your name appears in the case caption.

"Pro Se" designation — identify yourself as a self-represented litigant. You can write "Pro Se," "Pro Se Plaintiff," "Pro Se Defendant," or "Appearing Pro Se" depending on your role.

Mailing address — your current mailing address where the court and opposing parties can reach you. If this changes during litigation, you must file a notice of change of address immediately.

Phone number — a number where you can be reached. The court may need to contact you about scheduling or procedural issues.

Email address — the email associated with your CM/ECF account. This is where you'll receive electronic notifications of filings and court orders.

What Your Signature Means: Rule 11

Your signature on a court filing is not just a formality. Under Federal Rule of Civil Procedure 11, by signing a document filed with the court, you are certifying four things.

First, you're certifying that the filing is not being presented for an improper purpose — such as harassment, unnecessary delay, or needlessly increasing the cost of litigation.

Second, you're certifying that the legal claims, defenses, and arguments in the document are warranted by existing law or a non-frivolous argument for changing the law.

Third, you're certifying that the factual allegations have evidentiary support — or, if specifically identified, will likely have evidentiary support after further investigation or discovery.

Fourth, you're certifying that denials of factual allegations are warranted by the evidence — or, if specifically identified, are reasonably based on belief or a lack of information.

If the court finds that you violated Rule 11, it can impose sanctions — which can include monetary penalties, striking the offending filing, or other corrective measures. The court can act on its own or in response to a motion from the opposing party. Pro se litigants are held to the same Rule 11 standard as attorneys, though courts may apply it with somewhat more leniency given the liberal construction doctrine.

When You Still Need a Wet-Ink Signature

The /s/ format works for CM/ECF electronic filings. But there are situations where a handwritten signature is still required.

Paper filings. If you're filing at the clerk's office in person or by mail (because your court doesn't allow pro se e-filing or you haven't been granted CM/ECF access), your documents need an original handwritten signature in blue or black ink. Some courts are more flexible about this than others — check your local rules.

Declarations and affidavits. Documents submitted under penalty of perjury — like declarations (28 U.S.C. § 1746) and affidavits — may require original signatures depending on your court's rules. Many courts now accept /s/ signatures on declarations filed through CM/ECF, but some still require scanned originals. When in doubt, sign the original in ink, scan it, and file the scan.

Multi-party filings. When a document requires signatures from multiple parties (like a joint stipulation), each party's signature needs to be represented. You can either file a scanned document with all original handwritten signatures, or file electronically with /s/ signatures for each party plus a representation from the filing party that the others have reviewed and consented to the document.

Why DocuSign and Adobe Sign Cause Problems

Pro se filers sometimes try to use DocuSign, Adobe Sign, or similar digital signature platforms to sign court filings. This frequently causes problems. These platforms embed digital certificates, JavaScript, and invisible data layers into the PDF that CM/ECF's security scanner flags as prohibited content. The result is either a "document is malformed" rejection at upload or — worse — a PDF that appears to upload successfully but renders as black or blank pages when viewed through PACER.

The fix is simple: don't use these platforms for court filings. The /s/ text format is what courts expect. If you've already signed a document with DocuSign and need to file it, print the PDF to a new file to strip out the digital signature layers, then re-upload. For more on this, see our CM/ECF troubleshooting guide.

Signing Exhibits and Attachments

Exhibits and attachments attached to your filing do not need your /s/ signature — only the main filing document does. If your exhibit is a signed contract, a signed letter, or any document with someone else's signature, the existing signature on the exhibit is what it is. You're filing the exhibit as evidence, not signing it yourself.

However, if you're filing a declaration or affidavit as an attachment (for example, your own declaration in support of a motion), that declaration needs its own signature — either /s/ for e-filing or a scanned handwritten original, per your court's rules.

Certificate of Service Signatures

Many filings include a certificate of service at the end — a statement certifying how and when you served the document on other parties. The certificate of service should include its own /s/ signature and date. If your court's CM/ECF system provides automatic service to all registered parties, your certificate of service can state that service was accomplished through the court's electronic filing system. For parties not registered for electronic notification, you must separately serve them (usually by mail) and certify that in the certificate.

Signature on the Civil Cover Sheet

The JS 44 civil cover sheet — required when opening a new case — has a signature line at the bottom. Since you're typically filing the initial complaint on paper (even if you later e-file everything else), this usually requires a handwritten signature. If your court accepts the civil cover sheet electronically, /s/ works here too.

Keep It Simple

Federal court electronic signatures are deliberately low-tech. No special software, no digital certificates, no blockchain verification. Type /s/ Your Name, include your contact information below it, and file through CM/ECF. The system handles authentication through your login credentials. The simplicity is a feature — it means you can prepare and sign court documents from anywhere with a word processor, convert to PDF, and file.
