Missouri eFiling System — What Are the Requirements Under Rule 103 and Special Rule 21?
Missouri eFiling System (efile.courts.mo.gov), operated by OSCA, is the statewide electronic filing platform. Supreme Court Rule 103 mandates eFiling for all Missouri-licensed attorneys. Self-represented parties in the Southern District may file by mail, fax, or hand-delivery under Special Rule 21.

What Is the Missouri eFiling System and Who Must Use It?
Do you have to efile in Missouri courts?
Yes. If you are a licensed Missouri attorney: Supreme Court Rule 103 mandates electronic filing for all Missouri-licensed attorneys in every court operating on the Missouri eFiling System. Self-represented (pro se) parties are generally exempt from mandatory eFiling, though the Southern District of the Missouri Court of Appeals provides specific alternative options under Special Rule 21.
Missouri eFiling System (efile.courts.mo.gov) — the statewide electronic filing platform operated by the OSCA under Supreme Court Rule 103 and Court Operating Rule 27 — covers all circuit courts across Missouri’s 45 judicial circuits. Missouri eFiling System also covers all 3 districts of the Missouri Court of Appeals: Eastern District, Western District, and Southern District.
Missouri eFiling System does not cover the Missouri Supreme Court under the same portal. The Missouri Supreme Court uses a separate eFiling process through courts.mo.gov for briefs and motions filed directly at the Supreme Court level.
| Court Type | Mandatory for Attorneys? | Mandatory for Pro Se Parties? | Governing Rule |
|---|---|---|---|
| Circuit Courts — all 45 circuits (civil, criminal, domestic) | Yes | No | Rule 103, Court Operating Rule 27 |
| Missouri Court of Appeals — Eastern and Western Districts | Yes | Court-specific | Rule 103 |
| Missouri Court of Appeals — Southern District (pro se filers) | Yes (attorneys) | Optional — Special Rule 21 applies | Rule 103, Southern District Special Rule 21 |
| Missouri Supreme Court | Yes | Court-specific | Rule 103 |
What Self-Represented Parties Need to Know
Missouri eFiling System does not automatically grant pro se parties access to the attorney-level filing portal. Self-represented parties who want to file electronically may use the self-help portal provided by individual circuit courts. Self-represented parties in the Southern District of the Missouri Court of Appeals have the additional option of filing by mail, fax, or hand-delivery under Special Rule 21 — an alternative not available in the Eastern or Western Districts.
How Does Missouri eFiling Registration Differ From a CaseNet My Account?
Missouri eFiling System (efile.courts.mo.gov), governed under Supreme Court Rule 103, operates a registration system that is completely separate from a Missouri CaseNet My Account at courts.mo.gov/casenet. The 2 systems have different URLs, different login credentials, and different functions. Logging in to one does not give access to the other.
This distinction is absent from OSCA’s own eFiling FAQ and from the 16th Circuit’s civil eFiling guide. Attorneys who register for a CaseNet My Account expecting eFiling access will not be able to submit court documents through Missouri eFiling System until they complete a separate eFiling registration with MOBAR number verification.
| Attribute | Missouri eFiling Credential | CaseNet My Account |
|---|---|---|
| Portal URL | efile.courts.mo.gov | courts.mo.gov/casenet |
| Primary function | Submit court documents electronically | Track cases, view dockets, manage subscriptions |
| Who can register | Licensed Missouri attorneys only (MOBAR verification required) | Any member of the public |
| Registration method | Phone verification via OSCA at (573) 526-0062 or OSCA-verified online form | Self-service online registration, email only |
| MOBAR number required | Yes | No |
| Grants eFiling access | Yes | No |
| Grants Track This Case access | No — separate login required | Yes |
How Do You Register for the Missouri eFiling System?
How do I register for Missouri eFiling?
Contact OSCA at (573) 526-0062 with your Missouri Bar number ready. Missouri eFiling System registration requires OSCA staff to verify your MOBAR number before activating your account. Registration is not self-service. You cannot create an eFiling account through the efile.courts.mo.gov website without OSCA staff verification — unlike a CaseNet My Account, which requires no phone contact and no Bar number.
Missouri eFiling System registration, the account required to submit court documents electronically under Supreme Court Rule 103, requires verification of a valid Missouri Bar number before OSCA activates filing access. 5 steps complete the registration process:
- Confirm active Missouri Bar license: Verify your license is in active standing through the Missouri Bar’s online attorney directory before contacting OSCA. Suspended or inactive Bar numbers will not pass verification.
- Navigate to efile.courts.mo.gov: Access the Missouri eFiling System portal. New users must select the registration option. Do not attempt to log in using CaseNet My Account credentials.
- Complete the attorney registration form: Enter your full name, Missouri Bar number, law firm name (if applicable), and contact email address. The email entered becomes the eFiling notification address for all submissions.
- Call OSCA at (573) 526-0062 for MOBAR verification: An OSCA staff member will confirm your Missouri Bar number against the MOBAR registry. This step is required before your account is activated. Verification typically completes within 1 business day.
- Receive and save your eFiling credentials: OSCA emails login credentials after MOBAR verification is complete. Save these credentials separately from any CaseNet My Account login. The 2 sets of credentials are not interchangeable.
What PDF Format Does the Missouri eFiling System Require?
Missouri eFiling System, operated by OSCA under Rule 103, enforces document format requirements automatically before any court staff review. A document uploaded in a prohibited format is rejected immediately at submission.
The distinction between a searchable PDF and a scanned image PDF is the most common source of PDF rejection. A scanned image PDF is a picture of a document — the text cannot be selected or searched. A searchable PDF has an underlying text layer. Word processors generate searchable PDFs by default when using “Save as PDF” or “Export to PDF.” Scanning a paper document without running OCR produces a non-searchable image PDF that Missouri eFiling System will reject.
| PDF Type | Accepted by Missouri eFiling? | Source |
|---|---|---|
| Searchable PDF (text-selectable, generated from Word/WordPerfect) | Yes — required | Rule 103.04 |
| Scanned image PDF without OCR (non-searchable) | No — rejected | Rule 103.04 |
| PDF/A format | No — rejected | courts.mo.gov PDF FAQ |
| Password-protected PDF | No — rejected | courts.mo.gov PDF FAQ |
| Encrypted PDF | No — rejected | courts.mo.gov PDF FAQ |
| Digitally-certified PDF (with a certification signature) | No — rejected | courts.mo.gov PDF FAQ |
Why PDF/A Is Rejected Despite Being a Legal Archive Format
Missouri eFiling System rejects PDF/A format even though PDF/A is an ISO-standardized archival format used in many legal contexts. PDF/A embeds all fonts and color profiles for long-term archival fidelity. Missouri eFiling System’s document processing pipeline is incompatible with the self-contained font embedding that PDF/A requires. Firms whose document management systems default to PDF/A output must change the export setting to standard PDF before filing.
What File Size Limits Does the Missouri eFiling System Impose?
Missouri eFiling System imposes 2 automatic file size limits on every electronic submission: a 7.0 MB maximum for each individual document and a 21.0 MB maximum for the combined total of all documents in a single filing event. Both limits are applied simultaneously.
A multi-document filing that passes the 7.0 MB per-file test can still fail the 21.0 MB combined limit. A filer submitting 4 documents at 6.0 MB each has a 24.0 MB combined total — that submission is rejected despite each individual file being under the single-file cap.
| Limit Type | Maximum Size | Applies To | Consequence |
|---|---|---|---|
| Single document limit | 7.0 MB | Each individual PDF uploaded in the filing | Filing rejected at document upload |
| Combined submission limit | 21.0 MB | Total size of all documents in one filing event | Filing rejected at submission review |
How to Reduce PDF File Size Before Filing
3 methods reduce PDF file size to meet Missouri eFiling System limits, in order of effectiveness:
- Reduce image resolution in embedded graphics: Photographs and high-resolution exhibits embedded in a PDF generate the largest file sizes. Reduce embedded image resolution to 150 DPI before converting to PDF. Court documents rarely require image resolution above 150 DPI for legibility.
- Export from the source document rather than print-to-PDF: Exporting directly from Word or WordPerfect generates smaller, cleaner PDF files than the Windows “print to PDF” function. The print-to-PDF method often produces larger files with duplicate font data.
- Split large documents into separate filings: Missouri eFiling System allows multiple separate filing submissions on the same case. A 30-page exhibit package that exceeds 7.0 MB can be split into 2 separate exhibit filings, each under the 7.0 MB single-file cap and within the 21.0 MB combined cap.
What Is Southern District Special Rule 21?
Who is exempt from Missouri eFiling requirements?
Self-represented (pro se) parties are generally exempt from mandatory eFiling under Supreme Court Rule 103, which applies only to Missouri-licensed attorneys. In the Missouri Court of Appeals, Southern District, self-represented parties have an explicit procedural framework — Southern District Special Rule 21 — that authorizes filing by mail, fax, or hand-delivery. Pro se parties in the Eastern and Western Districts are not covered by Special Rule 21 and should confirm alternative filing options directly with the respective clerk’s office.
Southern District Special Rule 21 is a local procedural rule of the Missouri Court of Appeals, Southern District, that authorizes 3 non-electronic filing methods for pro se parties: mail, fax, and hand-delivery. Special Rule 21 does not require self-represented parties to register for Missouri eFiling System. Special Rule 21 does not apply to attorneys — licensed Missouri attorneys must file electronically through Missouri eFiling System under Rule 103 regardless of which Court of Appeals district their case is in.
| Filing Method | Missouri-Licensed Attorneys | Pro Se — Southern District | Pro Se — Eastern or Western District |
|---|---|---|---|
| Electronic filing via efile.courts.mo.gov | Mandatory under Rule 103 | Optional | Permitted where available |
| Prohibited — Rule 103 requires eFiling | Authorized — Special Rule 21 | Not covered by Special Rule 21 | |
| Fax | Prohibited — Rule 103 requires eFiling | Authorized — Special Rule 21 | Not covered by Special Rule 21 |
| Hand-delivery to clerk | Prohibited — Rule 103 requires eFiling | Authorized — Special Rule 21 | Not covered by Special Rule 21 |
Southern District Court of Appeals Location and Contact
Missouri Court of Appeals, Southern District, is headquartered in Springfield, Missouri. Self-represented parties using hand-delivery under Special Rule 21 must deliver documents to the Southern District clerk’s office during court business hours. Fax numbers and mailing address for the Southern District clerk are published at courts.mo.gov/page.jsp?id=163773.
How Do You Submit Documents Through the Missouri eFiling System?
Missouri eFiling System (efile.courts.mo.gov), requiring a separate registered account under Supreme Court Rule 103, processes each document submission through the following 7 steps:
- Sign in to efile.courts.mo.gov: Use your registered Missouri eFiling credentials. Do not enter CaseNet My Account login information here. If the system does not recognize your credentials, call OSCA at (573) 526-0062 before the filing deadline — do not attempt to create a new account under deadline pressure.
- Search for the case: Enter the case number, court location, or party name to locate the case. Verify the case number format before proceeding. Missouri case numbers include a county code, year, case type code, and sequence number. An incorrect case number routes the filing to the wrong case or generates an error.
- Select the submission type: Choose the applicable filing type from the list of accepted submission categories for that case. Filing type selection determines the court’s docket entry description and the service recipients automatically notified by the system.
- Upload the document as a searchable PDF: Select the file for upload. Missouri eFiling System checks file format and file size at upload. A document must be a searchable PDF at or below 7.0 MB. The system rejects non-searchable PDFs, PDF/A files, password-protected files, and encrypted files at this step.
- Add all additional documents: Upload all exhibits and attachments separately. Verify that the combined total of all documents does not exceed 21.0 MB before proceeding to the next step. Missouri eFiling System does not warn about the combined size limit until the submission review page.
- Enter filer information and add service contacts: Confirm the filing attorney’s name and Bar number. Add service contacts for all parties who must receive electronic service. Missouri eFiling System sends service notifications to opposing counsel who are registered on the case.
- Review, submit, and save the confirmation receipt: Review the submission summary for case number accuracy, filing type, document names, and service recipient list. Submit the filing. Save or print the timestamped confirmation receipt. The timestamp on the receipt establishes the filing date for deadline purposes.
What Changed in Missouri eFiling Redaction Requirements After July 1, 2026?
Missouri eFiling System’s redaction framework, which governs how confidential information is handled in electronically filed documents under Missouri Court Operating Rules, changed in 2 ways under the December 2025 Missouri Supreme Court refinement order:
| Filing Scenario | Before July 1, 2026 | On or After July 1, 2026 |
|---|---|---|
| Filer submits a redacted document only (no unredacted version simultaneously) | CRIF required | CRIF still required |
| Filer simultaneously submits both a redacted version and an unredacted version of the same document | CRIF required | CRIF no longer required |
| Filer submits an unredacted document only (no confidential information at issue) | No CRIF required | No CRIF required (no change) |
What a CRIF Is and Why the Simultaneous-Filing Condition Matters
A Confidential Redacted Information Sheet (CRIF) is a court form that identifies the location of redacted information in a publicly filed document and provides the sealed unredacted version to the court for review. Missouri eFiling System required a CRIF whenever redacted content appeared in any publicly filed document, regardless of whether the filer also submitted an unredacted version at the same time.
The December 2025 Missouri Supreme Court refinement order recognized that simultaneous submission of both versions serves the same court record-keeping purpose as the CRIF itself. Submitting both a redacted public version and an unredacted sealed version in the same filing event gives the court immediate access to the full document without the CRIF as an intermediary step.
The CRIF elimination condition is strict on the word “simultaneously.” A filer who submits the redacted version first and the unredacted version in a separate later filing does not meet the simultaneous-submission condition. The CRIF requirement applies to that filing.
How Does High-Volume Automated Filing Work in the Missouri eFiling System?
Missouri eFiling System offers high-volume automated filing through Missouri Judicial Exchange (MoJX) ECF integration, documented in OSCA FAQ #24 at courts.mo.gov. MoJX ECF is a system-to-system transfer method that allows qualifying law firms to route court filings directly from their practice management software to Missouri eFiling System without accessing the efile.courts.mo.gov web portal.
MoJX ECF integration is not available by default to all registered Missouri eFiling accounts. A law firm must request the automated transfer configuration directly through OSCA. OSCA determines eligibility based on filing volume and technical compatibility between the firm’s document management system and MoJX ECF specifications.
| Attribute | Standard Web Filing (efile.courts.mo.gov) | MoJX ECF Automated Filing |
|---|---|---|
| Access method | Manual — web browser, case-by-case | Automated — system-to-system data transfer |
| Who it is available to | All registered Missouri eFiling accounts | High-volume filers — OSCA approval required |
| Setup required | Standard eFiling account registration | MoJX ECF configuration through OSCA |
| OSCA FAQ reference | General eFiling FAQ — courts.mo.gov/page.jsp?id=46525 | FAQ #24 specifically — courts.mo.gov |
| Use case | Individual filings, small-volume practice | Firms filing 50 or more documents per day |
What Causes the Missouri eFiling System to Reject a Filing?
What happens if my eFiling is rejected in Missouri?
Missouri eFiling System sends an error message identifying the rejection reason at the time of submission. A rejected filing does not receive a timestamp and does not establish a filing date. The attorney must correct the identified deficiency and resubmit. If the rejection occurs close to a deadline, contact OSCA at (573) 526-0062 immediately — do not assume the first submission preserves the filing date. Only a successful submission with a timestamped confirmation receipt establishes the filing date.
Missouri eFiling System’s automated rejection system checks every submission against 8 conditions before routing it to court staff. The 8 rejection causes are:
- Non-searchable PDF: The document is a scanned image without an OCR text layer. Missouri eFiling System cannot index or process image-only PDFs. Rejection is immediate at the upload step.
- Prohibited PDF type: The document is PDF/A format, digitally-certified, encrypted, or password-protected. All 4 types are rejected. The rejection message identifies the specific prohibited format detected.
- Single document exceeds 7.0 MB: The uploaded file exceeds the per-document size limit. Missouri eFiling System rejects the document at upload, before submission review.
- Combined submission exceeds 21.0 MB: The total size of all uploaded documents in the filing exceeds the combined cap. Missouri eFiling System identifies this at the submission review step, after all individual documents have passed the 7.0 MB check.
- Password-protected or encrypted file: Any document upload that Missouri eFiling System cannot open for format verification is rejected as password-protected or encrypted. This includes documents where the creator restricted PDF editing but not viewing — Missouri eFiling System cannot distinguish permission-restricted PDFs from fully password-protected ones.
- Missing required fields: The submission form has unfilled required fields, including case number, filing type, filer information, or service contacts. Missouri eFiling System will not accept an incomplete submission form.
- Unrecognized case number: The case number entered does not match any active case in Missouri eFiling System’s court database for the selected court location. Verify the case number format — Missouri case numbers include a county code, year, case type code, and sequence number — before resubmitting.
- Attorney not registered on the eFiling system: The filing attorney’s Bar number is not found in Missouri eFiling System’s attorney registry. This occurs when an attorney has a CaseNet My Account but has not completed separate Missouri eFiling System registration with MOBAR verification through OSCA at (573) 526-0062.
