California Rules of Court, rule 2.251 governs electronic service in civil cases, setting out when e-service is allowed, when it is mandatory, how parties consent to it, and how it must be documented. Working together with Code of Civil Procedure section 1010.6, the rule applies to any document that could otherwise be served by mail, express mail, overnight delivery, or fax. If a statute or court rule requires personal service for a particular document, e-service is off the table for that document no matter what your case is doing otherwise.
When Electronic Service Is Required
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 the action must accept electronic service of documents that could otherwise go by mail, express mail, overnight delivery, or fax. Separately, rule 2.251(c) lets individual courts require electronic service in specified civil actions by local rule or court order. When a court does that, every party required to e-file must also serve electronically and accept electronic service from the other parties.
Many California superior courts have adopted local rules mandating e-filing and e-service in broad categories of civil cases. Once your court mandates e-filing, you are locked into e-service in both directions for the life of the case.
Self-Represented Parties
Self-represented litigants are carved out. 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. Code of Civil Procedure section 1010.6(c) says the same thing from the other direction: an unrepresented party may consent to e-service but cannot be forced into it.
Consent can be withdrawn. Under section 1010.6(c)(4), a self-represented party who previously agreed to electronic service may withdraw that consent at any time by filing the appropriate Judicial Council form with the court.
How to Give Consent
Whether you are self-represented or an attorney formalizing consent in a case where e-filing has not been ordered, rule 2.251(b) gives you the same options. 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 expressly state that agreement constitutes consent, or by filing Judicial Council form EFS-005-CV (Consent to Electronic Service and Notice of Electronic Service Address).
Note the gap this leaves: simply e-filing a document on your own does not count as consent to receive electronic service. Consent has to be given in one of the ways above.
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 e-service address of every party or person who has consented to, or is required to use, electronic service. Check the list before you serve anything. Serving to an outdated address creates problems you will not want to litigate.
Changing Your Electronic Service Address
If your e-service address changes while a case is pending, you must promptly file a notice of the change electronically with the court and serve it electronically on every other party and person entitled to service. Switching providers does not do this for you; the notice obligation is yours.
Rule 2.251(g)(3) adds a presumption that cuts against anyone who goes quiet. Your e-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. If you stop monitoring an old address without updating it, documents served there are still treated as properly served.
How to Serve and When It Counts
You can serve electronically by transmitting through an approved electronic filing service provider or, where the court permits, by sending directly to the other party’s electronic service address. Many courts that mandate e-filing also require an approved provider for both filing and service, so check your local rules before trying to serve by direct email.
Service is complete at the time of electronic transmission or, if you are using a provider, when the provider sends the electronic notification of service. Timing matters. Under Code of Civil Procedure section 1010.6(a)(4), a document served electronically on a court day (between 12:00 a.m. and 11:59:59 p.m.) is deemed served on that court day. A document served on a weekend or court holiday is deemed served on the next court day. That distinction can shift deadlines by a day or more.
Proof of Electronic Service
After serving electronically, you have to prepare and file a proof of electronic service. Code of Civil Procedure section 1013b sets out what the proof must contain:
- The electronic service address and the residence or business address of the person who performed the service.
- The date of the electronic service.
- The name and electronic service address of the person served.
- A statement confirming the document was served electronically.
The proof itself can be 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. A server familiar with the business’s routine electronic filing practices may instead submit an affidavit confirming the document would be served that same day in the ordinary course of business.
The Two-Court-Day Extension and Its Exceptions
Electronic service gives the receiving party a short cushion. Under Code of Civil Procedure 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 with where service lands in the week.
Three deadlines do not get the extension:
- Notice of intention to move for a new trial.
- Notice of intention to move to vacate judgment under Code of Civil Procedure section 663a.
- Notice of appeal.
Those deadlines are hard. Missing an appeal or new-trial deadline because you assumed 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. Code of Civil Procedure 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, and the Judicial Council has made a form available for the request. Qualifying situations may include 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 meaningful; routine inconvenience is unlikely to get you excused.
Redact Before You Serve
Electronic service makes documents easy to transmit and easy 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 likewise be truncated to the last four digits. The responsibility sits entirely on the parties and their attorneys; the court clerk will not screen your filings for compliance. Documents filed under seal or made confidential by court order or by operation of law are exempt. For everything else, 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.
