California Rules of Court, rule 2.251, governs how parties serve documents electronically in California civil cases. Read together with Code of Civil Procedure section 1010.6, it answers four practical questions: which documents may be served electronically, who has to accept electronic service, how consent is given or withdrawn, and how service is completed and proved. The rule reaches any document that could otherwise be served by mail, express mail, overnight delivery, or fax.
Which Documents Rule 2.251 Covers
Rule 2.251(a) permits electronic service for any document that could be served by mail, express mail, overnight delivery, or fax. If a statute or court rule requires personal service for a particular document, you cannot substitute electronic service, even in a case that otherwise runs entirely through e-filing. Check the specific requirement for the document in front of you before you send it.
Who Must Accept Electronic Service
Two provisions do most of the work. Under Code of Civil Procedure section 1010.6(b)(2), any party represented by an attorney who has appeared in an action must accept electronic service of documents that could otherwise be served by mail, express mail, overnight delivery, or fax. Separately, rule 2.251(c) lets an individual court require electronic service in specified civil actions through a local rule or court order. When a court does that, any party required to e-file must also serve electronically and accept electronic service from every other party.
Many Superior Courts have adopted local rules mandating electronic filing and service in broad categories of civil cases. Once your court mandates e-filing, you are effectively locked into e-service on both ends of the case.
Self-Represented Parties
Self-represented litigants are carved out of the mandatory requirements. Rule 2.251(c)(3)(B) provides that parties not required to file electronically, including self-represented parties, must be served through traditional methods unless they voluntarily agree to receive electronic service. Section 1010.6(c) reinforces this: an unrepresented party may consent to electronic service but cannot be forced into it.
If you are self-represented and want to opt in, you have two routes. You can serve a written notice on all parties stating you accept electronic service and file that notice with the court. Or you can consent electronically, either by agreeing to the terms of service with an electronic filing service provider whose terms explicitly say agreement means consent, or by filing Judicial Council form EFS-005-CV (Consent to Electronic Service and Notice of Electronic Service Address) with the court. E-filing a document on your own does not, by itself, count as consent to receive electronic service.
Consent is not permanent. Under section 1010.6(c)(4), a self-represented party who previously agreed to electronic service can withdraw that consent at any time by filing the appropriate Judicial Council form.
How Consent Works for Represented Parties
Even represented parties sometimes need to formally consent under rule 2.251(b), particularly in cases where the court has not ordered mandatory electronic filing. The methods mirror those for self-represented parties: serve a notice on all parties and file it with the court, or manifest consent electronically through a filing service provider or by filing form EFS-005-CV.
One detail catches people off guard. If you consent to electronic service and then use an electronic filing service provider to file and serve documents, rule 2.251(b)(2) treats that provider as your designated agent for receiving service. Other parties can serve you through the provider rather than sending documents to your personal email, and that arrangement continues until you formally designate a different agent.
The Electronic Service List
Every court that permits or requires electronic filing must maintain an electronic service list for each case and make it available electronically to all parties. The list carries the current electronic service addresses of every party or person who has consented to or is required to use electronic service. Before serving any document, check the list for each party’s current address. Serving to an outdated address is a problem you do not want.
Changing Your Electronic Service Address
If your electronic service address changes while the case is pending, you must promptly file a notice of the change electronically with the court and serve that notice electronically on every other party entitled to service. Hiring a new electronic filing service provider does not shift that duty; you still file and serve the change-of-address notice yourself.
A presumption works against silence. Under rule 2.251(g)(3), your electronic service address is presumed valid as long as you file documents from it and have not filed a notice saying it is no longer good. Stop monitoring an old address without updating it, and documents served there are still treated as properly served.
How to Serve and When Service Is Complete
You can serve electronically by transmitting the document through an approved electronic filing service provider or, where the court permits, by sending it directly to the other party’s electronic service address. Many courts that mandate e-filing also require use of an approved provider for both filing and service, so read the local rules before you try to serve by direct email.
Service is complete at the time of electronic transmission or, if you use a provider, at the time the provider sends the electronic notification of service. Timing then depends on the day. Under section 1010.6(a)(4), a document served electronically on a court day is deemed served that day; a document served on a weekend or court holiday is deemed served on the next court day. That distinction can shift a deadline by a day or more.
Proof of Electronic Service
After serving, you prepare and file a proof of electronic service. Code of Civil Procedure section 1013b requires the proof to include the electronic service address and the residence or business address of the person who served the document, the date of service, the name and electronic service address of the person served, and a statement that the document was served electronically.
The proof itself may take the form of an affidavit from a person over 18 who lives or works in the county where service occurs, a certificate from an active California State Bar member, or a certificate from the court clerk if the clerk performed the service. If the server is familiar with the business’s routine electronic filing practices, an affidavit stating the document would be served that same day in the ordinary course of business is also acceptable.
The Two-Court-Day Extension and Its Limits
Electronic service gives the receiving party a short cushion. Under section 1010.6(a)(3)(B), any response deadline or duty triggered by service of the document is extended by two court days when service is electronic. Court days exclude weekends and judicial holidays, so the calendar extension varies depending on when service falls in the week.
The extension does not apply to three filings:
- A notice of intention to move for a new trial.
- A notice of intention to move to vacate judgment under Code of Civil Procedure section 663a.
- A notice of appeal.
Those deadlines are hard. Electronic service does not buy extra time for any of them. Missing an appeal deadline or a new-trial motion deadline on the assumption that the two-day extension applied is the kind of mistake that cannot be undone.
Hardship Exemption
Attorneys and represented parties can seek relief from mandatory electronic service. Section 1010.6(g)(3) requires every court with a mandatory e-filing program to have a procedure for filing paper documents when the electronic requirement would cause undue hardship or significant prejudice. The Judicial Council has issued a form for the request. Situations that may qualify include a lack of reliable internet access, inability to convert certain documents to electronic format, or a technology barrier that would genuinely prevent compliance. The threshold is real; ordinary inconvenience is unlikely to get you excused.
Redact Before You Serve
Electronic service makes documents easier to transmit and easier to circulate. California Rules of Court, rule 1.201, requires parties and their attorneys to redact sensitive personal information from all documents filed with the court, whether paper or electronic. Social Security numbers must be limited to the last four digits, and financial account numbers must be truncated the same way. The rule places this responsibility on the parties and their attorneys; the clerk will not review your filings for compliance. If you need to include full identifiers, you can seek a court order to file a confidential reference list using the Judicial Council form for that purpose.
Documents filed under seal or made confidential by court order or operation of law are exempt from these redaction requirements. For everything else that touches the court’s public file, redact before you serve and file. Once a document with a full Social Security number hits an electronic filing system, pulling it back is far harder than getting it right the first time.
