Service Methods
| Method | Certificate Language | When | |--------|---------------------|------| | ECF/E-filing | "via the Court's CM/ECF system, which will send notification to all registered counsel of record" | Federal and most state e-filing systems | | Email | "via electronic mail to the email address(es) listed below" | Parties consented per FRCP 5(b)(2)(E) | | U.S. Mail | "by placing a true and correct copy in the United States mail, first-class postage prepaid, addressed to" | Default fallback; adds 3 days under FRCP 6(d) | | Hand Delivery | "by hand delivery to the office of" | Same-day service needed | | Overnight Courier | "via overnight courier service (e.g., FedEx, UPS) to" | Time-sensitive, mail too slow |
Workflow
- Federal ECF-only: Use short-form certificate — no individual addresses needed. Reference CM/ECF notification to all registered counsel.
- Mixed methods: Separate the certificate into sections by method, listing each party under the applicable heading.
- Signature block: Always include bar number, firm, address, phone, email.
- Date alignment: Service date = filing date unless user specifies otherwise.
- Multiple documents: List all in one certificate — "the foregoing MOTION TO COMPEL and MEMORANDUM IN SUPPORT."
Key Rules
- FRCP 5(b): Governs federal service methods. ECF service complete upon transmission.
- FRCP 6(d): +3 calendar days to response deadlines for mail service.
- State variations: Many mirror FRCP 5. California: CCP 1013 (mail), CCP 1010.6 (electronic). New York: CPLR 2103. Always check local rules.
- Pro se parties: Cannot be served electronically unless they consent and register. Serve by mail or hand delivery.
