How do you serve a lawsuit on someone in prison? California's answer.
A civil case cannot move forward until the defendant is served. But what happens when the person you need to sue is behind bars? Process servers cannot simply walk into a cell block, and plaintiffs sometimes assume an incarcerated defendant is effectively out of reach. California law says otherwise — and for abuse survivors suing a perpetrator who is now serving time, this question is not academic.
The jailer is the doorway
The key is Penal Code section 4013. When a paper in a judicial proceeding directed to an incarcerated person is served on the warden, sheriff, or jailer, that official must "forthwith deliver" it to the prisoner, noting the exact time of service. An official who neglects that duty is civilly liable to the prisoner for resulting damages.
Courts have read this mandatory duty together with Code of Civil Procedure section 416.90, which permits service on "a person authorized by [the defendant] to receive service of process" or one authorized by law. Because the statute obligates the custodial official to deliver the papers, the official is treated as an agent authorized by law to accept service on the inmate's behalf. That is the holding of Sakaguchi v. Sakaguchi (2009) 173 Cal.App.4th 852 and, more recently, Crane v. Dolihite (2021) 70 Cal.App.5th 772 — including delivery to a prison's designated litigation coordinator.
Two recognized methods
Personal service. Hand-delivering the summons and complaint to the warden, sheriff, jailer, or litigation coordinator who has custody of the defendant satisfies personal service, just as delivery to any authorized agent would. (Sakaguchi; American Express Centurion Bank v. Zara (2011) 199 Cal.App.4th 383.)
Service by mail with acknowledgment. Alternatively, mail the summons and complaint to the institution's litigation coordinator with two copies of the notice and acknowledgment of receipt and a postage-prepaid return envelope. Service is complete when the authorized official signs and dates the acknowledgment; the official then delivers the papers to the inmate.
Practical tips
Before serving, locate the defendant precisely — CDCR's online inmate locator will identify the institution — and call the facility's litigation coordinator to confirm the correct recipient and any institution-specific procedures. Document everything: the proof of service should identify the official served and their authority to accept. And keep the timeline in mind; locating and serving an incarcerated defendant takes longer than routine service, so start early within the summons deadlines.
Why this matters in abuse cases
In many of the cases I handle, the perpetrator's criminal conviction is what finally makes a civil suit possible — and by then, the defendant is in custody. Incarceration does not shield a defendant from civil accountability, and it does not stop a survivor from obtaining a judgment. It just changes the mechanics of the first step.
If you need to pursue a civil claim against an incarcerated defendant, I am happy to walk through the process in a confidential consultation.
