Filing a Petition and Summons only opens the door to a California divorce case. The Respondent still has to be formally notified, and the court needs proof that it happened correctly. That proof is Form FL-115, Proof of Service of Summons.
Key Takeaway: Form FL-115 is signed by the person who served the papers, not by the Petitioner. It documents who was served, what was delivered, and the date, time, place, and method of service. Filing it starts California's mandatory 6-month waiting period and lets the case move forward.
Form FL-115 is the California Judicial Council form titled "Proof of Service of Summons." It is a sworn statement, completed and signed under penalty of perjury by the person who delivered the divorce papers, confirming that service actually happened and describing exactly how.
Once the Summons (FL-110) and Petition (FL-100) are filed, they still have to be delivered to the Respondent before the case can proceed. FL-115 is the record the court relies on to confirm that delivery met California's legal requirements. Without it, the court has no verified way to know the Respondent was ever notified.
If you have not yet filed the documents that FL-115 proves were served, our guide on How to Fill Out Form FL-100 walks through that starting form in detail.
Service rules in California are strict about who is allowed to hand over the papers.
The person who serves the Summons and Petition must be:
- At least 18 years old
- Not a party to the case
That second requirement matters more than people expect. The Petitioner, the person who filed the case, can never serve their own papers, no matter how straightforward or amicable the situation is. The reasoning is simple: the court needs an independent, neutral confirmation that service happened, and a party to the case cannot provide that.
Eligible servers commonly include a friend, an adult family member who is not part of the case, a coworker, or a professional process server. Many people choose a process server specifically because they are experienced with the paperwork and the follow-up steps required if the Respondent is difficult to locate.
If the Petitioner attempts to serve their own papers, the service is invalid. The court will not accept a Proof of Service signed by a party, and service will need to be completed again by an eligible adult.
The Respondent generally must receive copies, not originals, of everything that has been filed so far, most commonly:
- The Summons (FL-110)
- The Petition (FL-100)
- A blank Response form (FL-120), so the Respondent has what they need to reply
- Any UCCJEA declaration, if minor children are involved
- Any other paperwork filed alongside the Petition, such as a request for a fee waiver
Form FL-115 asks the server to identify exactly which documents were delivered. This list should match what was actually filed with the court. Leaving out a document, or serving an outdated version of one, can create problems later if the Respondent challenges whether they received proper notice.
<h2 id="methods-of-service">Methods of Service</h2>California recognizes a few valid ways to serve divorce papers, and FL-115 asks the server to specify which one was used.
| Method | How It Works | When It's Typically Used |
|---|---|---|
| Personal service | An eligible adult hands the documents directly to the Respondent | The most straightforward method, used whenever the Respondent can be reached directly |
| Substituted service | After reasonable attempts to personally serve fail, documents are left with another responsible adult at the Respondent's home or workplace and then also mailed to the Respondent | The Respondent is avoiding personal contact or is difficult to reach directly |
| Service by mail with notice and acknowledgment | Documents are mailed to the Respondent along with a Notice and Acknowledgment of Receipt (FL-117), which the Respondent signs and returns | Both spouses are cooperative and the Respondent agrees to accept service this way |
Each method has its own procedural requirements, and substituted service in particular has specific follow-up steps (including additional mailing) that must be completed correctly for service to be valid. If there is any doubt about which method applies to your situation, confirm the requirements with your county Superior Court self-help center before proceeding.
<h2 id="section-by-section">Completing Form FL-115, Section by Section</h2>Here is what the server actually fills in.
1. Case Information
The top of the form identifies the county, the case number, and the names of the Petitioner and Respondent, matching what appears on the Petition and Summons already on file.
2. Who Was Served
The server states the full legal name of the person served. If service was substituted, this section also identifies the responsible adult who accepted the documents on the Respondent's behalf.
3. What Was Served
The server checks or lists which documents were delivered, matching them against what was actually filed with the court.
4. Date, Time, and Place of Service
This is one of the most important sections on the form. The server records the exact date service occurred, along with the time and location (a home address, workplace, or other location where the delivery happened).
The date recorded here is not a formality. It is the date California's mandatory 6-month waiting period begins, so it must be accurate and match the server's own recollection or notes.
5. Method of Service
The server indicates whether service was personal, substituted, or by mail with a Notice and Acknowledgment of Receipt, and completes any additional details required for that specific method.
6. Server's Information and Signature
The server prints their name, address, and, if applicable, registration information (for a professional process server), then signs the form under penalty of perjury confirming that everything stated is true.
California requires a mandatory 6-month waiting period before a dissolution can be finalized, and that clock starts on the date of service, not the date the Petition was filed. This is a detail people frequently misunderstand.
Filing the Petition early does not shorten the waiting period. The waiting period cannot begin until the Respondent has actually been served and that service has been documented on a filed FL-115. A delay in serving the Respondent, or a Proof of Service that is filed late, pushes back the earliest possible date the case can be finalized.

<h2 id="common-mistakes">Common Mistakes to Avoid</h2>- Trying to serve your own papers as the Petitioner, which makes the service invalid
- Recording an incorrect or approximate service date instead of the exact date service occurred
- Choosing the wrong method of service for the situation, such as attempting substituted service without completing the required follow-up mailing
- Leaving out a document that was actually served, or listing one that wasn't
- Forgetting to have the server sign the form under penalty of perjury
- Never filing the completed Proof of Service, which leaves the court without evidence that service happened at all
Once the server has completed and signed Form FL-115, it has to be filed with the same Superior Court where the case is pending. This step is easy to overlook, since it happens after the more visible steps of filing and serving, but the case cannot progress without it.
Until FL-115 is on file:
- The court has no verified record that the Respondent was notified of the case
- The 30-day period for the Respondent to file a Response has not been established
- The mandatory 6-month waiting period is not considered to have started
- The case cannot move toward a default judgment if the Respondent does not respond, or toward finalization once both sides are ready
Pro Tip: File the Proof of Service as soon as it is completed and signed. Keep a copy for your own records, since it may be needed again if the Respondent later disputes whether or how they were served.
What is Form FL-115 used for?
Form FL-115 is the California Judicial Council Proof of Service of Summons. It is the sworn statement the server signs to tell the court exactly who was served, what documents they received, and when, where, and how service happened. Filing it is what proves to the court that the Respondent was legally notified of the case.
Who can serve divorce papers in California?
Anyone who is at least 18 years old and is not a party to the case can serve the Summons and Petition. This can be a friend, relative, coworker, or a professional process server. It cannot be the Petitioner, since a party can never serve their own papers in their own case.
Can I serve my own divorce papers?
No. California does not allow a party to a case to serve their own papers, even if the other spouse is cooperative and expecting the documents. Someone else, an adult who is not part of the case, must physically deliver the Summons and Petition and then sign the Proof of Service.
What is the difference between personal service and substituted service?
Personal service means an eligible adult hands the documents directly to the Respondent. Substituted service is used when the Respondent cannot be personally reached after reasonable attempts, and instead the documents are left with another responsible adult at the Respondent's home or workplace and then also mailed to the Respondent, with specific follow-up steps required by law.
What happens if Form FL-115 is never filed?
Without a filed Proof of Service, the court has no record that the Respondent was properly notified of the case. The case cannot move forward toward a default judgment or a finalized dissolution until a completed, accurate Proof of Service is on file with the court.
Does the 6-month waiting period start on the date I filed the Petition or the date of service?
California's mandatory 6-month waiting period begins on the date the Respondent was served, not the date the Petitioner filed the Petition. This is one of the main reasons the date recorded on Form FL-115 has to be accurate.
What should I do if I think service was done incorrectly?
If the method, timing, or paperwork involved in service does not appear to meet California's requirements, it is worth confirming the details with your county Superior Court self-help center before filing the Proof of Service, since a defective proof of service can be challenged later and may need to be redone.
How Virdix Helps With Proof of Service
Proof of service problems are rarely about the law being complicated. They come from small details: a service date that doesn't match the method used, a document list that doesn't line up with what was actually filed, or a form that never gets filed at all. Virdix is built to help you avoid that:
- Guided questions, so the server's information and the service details are captured accurately
- Consistency checks, so the documents listed on FL-115 match what you actually filed
- Clear next steps, so you know the Proof of Service still needs to be filed after it's signed
- County-specific filing details, so you know exactly where and how to submit it
Virdix does not serve papers or provide legal advice, but it helps make sure your Proof of Service is complete and consistent once service has happened.
