How to Serve Divorce Papers in Contra Costa County
Why Proper Service Is the Foundation of Your Divorce Case
In California, a divorce (dissolution of marriage) cannot proceed until the other spouse has been properly served with the initial papers. The Contra Costa County Superior Court requires evidence of proper service — in the form of a completed Proof of Service of Summons (form FL-115) — before the case can move forward. Without proper service, your case timeline is frozen, and you cannot obtain a default judgment if your spouse doesn't respond.
Who Can Serve Divorce Papers in California
California law prohibits the filing party from serving their own spouse — the service must be performed by a third party. That person must be at least 18 years old and not a party to the case. You can ask a friend or family member to serve the papers, but using a professional process server is strongly recommended. A professional ensures the documents are served correctly, documents the service properly, and completes the FL-115 form accurately.
What Documents Need to Be Served
The initial service package in a California divorce typically includes: the Summons — Family Law (FL-110), the Petition for Dissolution of Marriage (FL-100), any attachments to the petition, and possibly temporary order requests if filed. If there are children involved, the Preliminary Declaration of Disclosure (FL-140) must also eventually be served. Your attorney or the court's self-help center can advise on the complete package for your specific situation.
Personal Service vs. Service by Mail With Acknowledgment
Personal service — hand-delivering the documents to your spouse — is the most reliable method and requires no cooperation from the respondent. If your spouse is cooperative and willing to sign an acknowledgment of receipt, service by mail with acknowledgment (CCP 415.30) is another option: you mail the documents and a Notice and Acknowledgment form (FL-117), and the respondent signs and returns the acknowledgment. If they don't return it, you'll need personal service.
Completing the Proof of Service (FL-115)
After service is complete, the person who served the papers (not you) must complete form FL-115, Proof of Service of Summons. This form documents: the server's name and address, the date and location of service, the method used, and which documents were served. The completed FL-115 is filed with the Contra Costa County Superior Court at 725 Court Street in Martinez. Once filed, the respondent's 30-day response period begins running (or in some cases, from the date of service).
What If Your Spouse Won't Accept Service or Can't Be Found
If your spouse avoids service, a professional process server can make multiple attempts at different times and locations. After demonstrating reasonable diligence, substitute service at their home or workplace may be authorized. If your spouse's location is genuinely unknown, you can petition the court for service by publication. This is a last resort but ensures the case can still proceed.
Frequently Asked Questions
Can I serve my spouse myself in a California divorce?
No. California law requires that someone other than the filing party serve the divorce papers. The server must be at least 18 years old and not a party to the case.
What form is used for proof of service in a California divorce?
Judicial Council form FL-115 (Proof of Service of Summons — Family Law) is the standard form. It must be completed by the person who served the papers and filed with the court.
What if my spouse is in another state?
You can serve a spouse in another state. California has jurisdiction over the divorce if either spouse meets the residency requirements (6 months in California, 3 months in the county). Out-of-state service follows the state where service occurs, but California courts accept properly documented out-of-state service.
How long does my spouse have to respond after being served?
After being served in California, the respondent has 30 days to file a Response (FL-120) with the court. If served outside California but within the United States, they generally have 40 days.
