After you file for divorce in California, you must legally notify your spouse by having the paperwork served on them. Serving divorce papers is not optional, and you cannot personally serve the initial papers yourself.
Another adult who is not a party to the case must deliver the required documents using an approved method. After service, the server completes the appropriate proof of service so the court has a record that your spouse was formally notified.
This guide explains how to serve divorce papers in California, who can serve them, personal service versus service by mail, Forms FL-115 and FL-117, alternative service methods, common deadlines, and what service may cost.

What Does It Mean to Serve Divorce Papers?
“Service” is the formal process of delivering filed court documents to your spouse, who is called the respondent, so they receive official notice that a divorce case has been started.
Simply telling your spouse that you filed for divorce is not the same as legally serving the papers.
In California, the petitioner cannot personally serve the initial divorce papers. Another qualified adult must deliver them, and the service must then be documented for the court.
If you have not yet filed your divorce, review our guide to the documents needed for divorce filing before moving to the service stage.
What Papers Must Be Served?
The exact documents depend on your case, but a typical initial California divorce service package includes:
- Petition — Marriage/Domestic Partnership (FL-100)
- Summons (FL-110)
- A blank Response — Marriage/Domestic Partnership (FL-120)
- Declaration Under Uniform Child Custody Jurisdiction and Enforcement Act (FL-105) if you and your spouse have minor children together
- Any additional filed papers that must be served
- Any additional blank forms your spouse may need to respond
Confidential fee-waiver documents generally should not simply be included with the ordinary service packet.
If you are still preparing your case, our step-by-step uncontested divorce guide explains the broader filing process.
Who Can Serve Divorce Papers in California?
The person serving the papers must generally:
- Be 18 years old or older
- Not be a party to the divorce case
- Follow the required method of service
- Complete the appropriate proof of service afterward
Common choices include:
- A friend or relative who is at least 18 and not involved in the case
- A registered professional process server
- A county sheriff where sheriff service is available
You cannot serve your own initial divorce papers.
Methods of Serving Divorce Papers in California
California provides several ways to serve divorce papers. The correct method depends on whether your spouse is cooperative, can be located, lives outside California, or has other special circumstances.
1. Personal Service
Personal service is the usual method for serving initial divorce papers.
Your server personally gives the documents to your spouse.
If your spouse refuses to physically take the papers, that does not necessarily prevent personal service. The California Courts Self-Help Guide explains that the server may leave the documents next to the person and clearly tell them that they are important legal papers.
If a qualified friend or relative performs personal service, there may be no service fee.
A professional process server may charge a fee based on location, number of attempts, urgency, and other factors.
2. Service by Mail With Notice and Acknowledgment of Receipt (FL-117)
If your spouse is cooperative, service may be completed by mail using Notice and Acknowledgment of Receipt (FL-117).
You still cannot mail the papers yourself.
An adult who is at least 18 and is not a party to the case acts as the server and mails:
- The required divorce papers
- Form FL-117
- The required copies
- A properly addressed, postage-paid return envelope
Your spouse must sign and return the acknowledgment.
Service is complete on the date your spouse signs FL-117, not on the date the papers were mailed.
If your spouse does not sign and return the form, this method has not completed service and another method may be necessary.
The server then completes the appropriate proof of service and attaches the signed acknowledgment.
3. Substituted Service
If your server repeatedly tries to personally serve your spouse but cannot find them at home or work, substituted service may become available.
California Courts instructs that the server generally should attempt personal service at least three times, on different days and at different times when the person is reasonably likely to be present.
The server may then leave the documents with an appropriate adult:
- At your spouse’s home, with a responsible adult who lives there, or
- At your spouse’s workplace, with an adult who appears to be in charge
The server must tell that person that the documents are legal papers intended for your spouse.
The server must then mail another copy of the papers to your spouse at the same address.
Declaration of Diligence
The server must document the attempts made to personally serve your spouse.
This typically includes:
- Dates
- Times
- Locations
- What happened during each attempt
The server prepares a Declaration of Diligence and completes the applicable Proof of Service.
For family-law substituted service, Proof of Service of Summons (FL-115) is used.
Service is generally considered complete 10 days after the papers are mailed.
Because the response period begins after service is complete, substituted service can effectively give the respondent approximately 40 days from the mailing date to respond.
4. Service by Publication
If you genuinely cannot locate your spouse after making reasonable efforts, you may be able to ask the court for permission to serve by publication.
This is not simply an alternative you can choose because personal service is inconvenient.
You generally must show the court that you made diligent attempts to locate your spouse.
If the judge approves publication, notice of the case is published in a court-approved newspaper according to the court’s instructions.
California Courts describes the publication period as running for four consecutive weeks.
After the required publication period, additional time must pass before a default can be requested if your spouse does not respond.
5. Service by Posting
Service by posting is different from service by publication.
In qualifying cases, generally involving a person who has permission to use a fee waiver, the court may allow the required notice to be posted at the courthouse instead of published in a newspaper.
California Courts describes the posting period as 28 days.
The judge must approve this method.
If the court orders posting, additional mailing and proof-of-service requirements can also apply.
6. Serving a Spouse Who Lives Outside California
A spouse who lives in another state can still be served.
One option is personal service in the state where your spouse lives.
California Courts also explains that certain out-of-state situations may allow service by registered or certified mail with return receipt requested.
Another adult—not the petitioner—must handle the mailing.
The requirements should be followed carefully because interstate service rules can affect whether service is valid.
7. Serving Divorce Papers Internationally
Serving a spouse in another country can be considerably more complicated.
The correct procedure may depend on:
- The country where your spouse lives
- International treaties
- Whether that country is covered by the Hague Service Convention
- The type of documents being served
International service should not automatically be handled like ordinary domestic mail.
If international service requirements are unclear, consider using the California court self-help resources or consulting a qualified family-law attorney.
8. Serving a Spouse Who Is Incarcerated
If your spouse is in jail or prison, special procedures may apply.
California Courts instructs filers to contact the facility because an authorized jail or prison official may be involved in serving the papers and documenting when service occurred.
Confirm the institution’s current service requirements before sending documents.
What If Your Spouse Is in the Military?
Military status can create additional procedural considerations and federal protections.
For example, the Servicemembers Civil Relief Act can affect certain default proceedings when a party is on active military duty.
Military cases can become more complicated than ordinary service situations, so additional legal guidance may be appropriate when military protections are involved.
What Happens If Your Spouse Refuses the Papers?
Your spouse generally cannot stop the divorce simply by refusing to hold the documents.
If a server personally approaches your spouse and the spouse refuses to take the papers, California Courts explains that the server can leave the documents next to them and tell them what they are.
The important question is whether the legal requirements for valid service were satisfied—not whether the respondent wanted to receive the papers.
What If Your Spouse Is Avoiding Service?
Repeatedly avoiding a process server does not necessarily prevent a divorce from moving forward.
Depending on the circumstances, your options may eventually include:
- Substituted service
- Service by publication
- Service by posting
However, these methods have additional requirements.
A record of attempts to personally serve your spouse can become important if you later ask the court to authorize another method.
When Do You Have to Serve Divorce Papers?
Initial divorce papers are served after they have been filed with the court.
For an ordinary divorce petition without an upcoming hearing, you should not assume that the commonly mentioned 16-court-day rule is a universal deadline for serving the original divorce petition.
That timing becomes particularly important when papers are connected to a scheduled court hearing, such as a Request for Order.
When an applicable hearing requires personal service, service generally must occur sufficiently before the hearing under the rules governing that request. Mailing can require additional time.
Always check the instructions for the specific papers you filed and any local court requirements.
How Long Does Your Spouse Have to Respond?
After valid service is complete, a spouse who was personally served generally has 30 days to file a Response.
For service by Notice and Acknowledgment of Receipt, service is complete when the recipient signs the acknowledgment, and the response period runs from that date.
For substituted service, service is complete 10 days after mailing, so the timing works differently.
What the respondent files is a separate topic that will be covered in our dedicated guide:
How to Respond to Divorce Papers in California
If the respondent does not respond by the applicable deadline, the petitioner may eventually be able to pursue a default. That procedure will be covered separately in:
Default Divorce in California: What Happens When a Spouse Doesn’t Respond?
You can also read what happens after divorce papers are filed for an overview of the next stages.
Proof of Service of Summons: FL-115
For many methods of serving the initial California divorce summons and petition, the server completes Proof of Service of Summons (FL-115).
The form records information such as:
- Who was served
- Who served the papers
- When service occurred
- Where service occurred
- How the papers were served
The server—not the petitioner—signs the proof of service.
The completed form is then filed with the court.
How FL-115 Works With FL-117
FL-115 and FL-117 serve different purposes.
FL-117 — Notice and Acknowledgment of Receipt shows that your spouse agreed to receive the papers by mail and signed an acknowledgment confirming receipt.
The server still completes the applicable proof of service and attaches the signed acknowledgment.
Do not assume that simply mailing FL-117 proves service.
Service by this method is not complete until your spouse signs the acknowledgment.
How Much Does It Cost to Serve Divorce Papers?
The cost depends on the method you use.
Friend or relative
If an eligible friend or relative serves the papers, there may be no service fee.
Professional process server
Professional process servers set their own fees.
The price can vary depending on:
- Geographic area
- Distance
- Number of attempts
- Rush service
- Difficulty locating the respondent
Ask the process server for a current quote rather than relying on a generic statewide price.
Sheriff service
Sheriff departments may charge a service fee.
Fees and availability vary by county.
If you have an approved court fee waiver, certain sheriff-service costs may also qualify to be waived.
Publication
Publication fees depend on the newspaper and location.
Because publication may run for several weeks, obtain a current quote directly from the court-approved publication before estimating the total cost.
Does Serving Divorce Papers Start California’s Six-Month Waiting Period?
Service is important to California’s minimum divorce waiting period.
A California divorce cannot generally become final until at least six months have passed from the applicable triggering event, such as service of the summons and petition or the respondent’s appearance.
This does not mean a divorce automatically ends six months after service.
Other requirements still have to be completed before the court can enter a final judgment.
Read our California divorce timeline guide for a broader explanation of the process.
Common Mistakes When Serving Divorce Papers
Serving the papers yourself
The petitioner cannot personally serve the initial divorce papers.
Forgetting the blank Response
A blank FL-120 is generally included so your spouse has the form available if they choose to respond.
Assuming ordinary mail is enough
Simply putting divorce papers in the mail does not automatically complete service.
Service by mail using FL-117 depends on your spouse signing and returning the acknowledgment.
Failing to file proof of service
Completing service is only part of the process.
The appropriate proof needs to be completed and filed with the court.
Using substituted service too soon
Substituted service generally requires multiple attempts at personal service first.
Assuming publication is an easy substitute
Publication usually requires court approval and evidence that reasonable efforts were made to locate your spouse.
Confusing publication and posting
They are separate methods with different requirements.
Assuming every service situation has the same deadline
Timing can depend on:
- The papers being served
- The method of service
- Whether a court hearing has been scheduled
- Local court requirements

Frequently Asked Questions
Can I serve my spouse divorce papers myself in California?
No. The person who filed the divorce case cannot personally serve the initial papers. Another adult who is at least 18 and is not a party to the case must serve them.
Can a friend serve divorce papers in California?
Yes. A friend or relative can generally serve the papers if they are at least 18 years old, are not a party to the case, and follow the correct service procedure.
Do I need a professional process server?
Not necessarily. A qualified friend or relative may perform personal service. A professional process server can be helpful if your spouse is difficult to locate, frequently unavailable, or avoiding service.
Can divorce papers be served by mail in California?
Yes, in certain situations. When using Notice and Acknowledgment of Receipt (FL-117), another adult mails the papers and your spouse must sign and return the acknowledgment. Service is complete when the acknowledgment is signed.
Can I serve divorce papers by certified mail?
Certified or registered mail can be relevant in certain situations, including some out-of-state service scenarios, but it should not be treated as a universal substitute for California’s ordinary personal-service requirements. Follow the rules that apply to your spouse’s location and your method of service.
What is FL-115?
FL-115 is the Proof of Service of Summons used in California family-law cases to document service of the initial summons and related papers.
What is FL-117?
FL-117 is the Notice and Acknowledgment of Receipt. It can be used when your spouse agrees to receive the initial papers by mail and signs the acknowledgment confirming receipt.
What happens if my spouse does not sign FL-117?
If your spouse does not sign and return the acknowledgment, service by that method is not complete. You will generally need another valid method, such as personal service.
What happens if my spouse avoids being served?
Avoiding service does not necessarily stop the divorce. After documented attempts at personal service, substituted service may become possible. If your spouse genuinely cannot be located, you may be able to request permission for service by publication or posting.
How many times should someone try to personally serve my spouse before substituted service?
California Courts instructs servers seeking substituted service to make at least three attempts, on different days and at different times when the respondent is reasonably likely to be available.
How long does my spouse have to respond after personal service?
Generally, 30 days after service. Different service methods can affect when service is considered complete, so the response deadline should be calculated from the correct completion date.
What happens if my spouse does not respond?
If the applicable response deadline passes without a Response being filed, the petitioner may be able to begin the default process. Default has separate procedural requirements and does not mean the petitioner automatically receives everything requested.
Does serving divorce papers mean the divorce is finished?
No. Service formally notifies your spouse that the case exists. Financial disclosures, agreements or court decisions, judgment documents, waiting periods, and other steps may still need to be completed before the divorce is final.
