You file California Judicial Council Form FL-115 to prove that the other party in your family law case received the Summons, Petition, and any related papers. Without a properly completed FL-115 on file, the court treats the responding party as never having been notified, which freezes your case and blocks default judgment under California Code of Civil Procedure § 417.10.
The stakes are real. According to the Judicial Council of California 2024 Court Statistics Report, more than 130,000 dissolution petitions are filed each year, and improper service is among the top three reasons clerks reject filings. A defective FL-115 can erase months of work, restart fee timers, and even expose the filer to a motion to quash service under CCP § 418.10.

What California Form FL-115 Actually Is
California Form FL-115, titled Proof of Service of Summons, is the sworn statement filed by the person who delivered your family law papers to the other side. The form is published by the Judicial Council of California and is mandatory in every dissolution, legal separation, nullity, parentage, and Uniform Parentage Act case where a Summons (Form FL-110) is issued. It is the family law cousin of the general civil POS-010 and is required by California Rules of Court, Rule 5.68.
The form has one core job. It tells the judge that the respondent received actual or legally sufficient notice of the lawsuit so the court has personal jurisdiction. Without that jurisdiction, every order the judge signs after that point can be voided under the seminal due-process ruling in Mullane v. Central Hanover Bank, which California courts continue to apply in family cases.
The consequence of skipping or botching FL-115 is severe. The clerk will reject your default request on FL-165, the six-month waiting period under Family Code § 2339 does not start, and the case sits dormant until you serve again and file a corrected proof.
A common misconception is that FL-115 itself accomplishes service. It does not. Service is the physical delivery of the papers; FL-115 is only the receipt that proves the delivery happened.
Who Can Serve the Papers and Sign FL-115
California law is strict about who may carry out service. Under CCP § 414.10, the server must be at least 18 years old and not a party to the case. That means the petitioning spouse may never personally hand the papers to the respondent and then sign FL-115, no matter how amicable the divorce.
The server may be a friend, a relative, a registered California process server, a county sheriff, a marshal, or a constable. Registered process servers must include their county of registration and registration number on the form, as required by the Business and Professions Code § 22350. Sheriffs charge a statutory fee set by Government Code § 26721, currently around forty dollars in most counties.
The plain-English version is simple. The petitioner cannot serve the petitioner’s own papers, ever.
The consequence of self-service is automatic invalidation. In Sakaguchi v. Sakaguchi (2009) 173 Cal.App.4th 852, the appellate court reaffirmed that service by a party is void on its face and cannot be cured by the respondent’s actual knowledge of the case.
Imagine a real-world example. Priya wants to save money and hands her husband Ravi the divorce papers herself at their kitchen table. Even though Ravi clearly received the documents, the court must reject the FL-115 because Priya is a party. Priya must start over by hiring a server and paying a second filing-related cost.
A common misconception is that a roommate or new romantic partner cannot serve. They can, as long as they are 18 or older and not named in the case caption.
Choosing the Right Service Method Before You Fill Out FL-115
Before you check any box on FL-115, you must pick the legally correct service method for your facts. California recognizes four primary methods in family law: personal service, substituted service, service by mail with notice and acknowledgment, and service by publication or posting. Each method maps to a specific section of the Code of Civil Procedure and to a specific check-the-box on FL-115.
Personal Service Under CCP § 415.10
Personal service is the gold standard and is described in CCP § 415.10. The server hands the papers directly to the respondent, says something like “you have been served,” and notes the date, time, and place.
Personal service is effective the moment the papers touch the respondent’s hand. The consequence of choosing this method is that the response clock starts immediately, giving the respondent 30 days to file an FL-120 Response under Family Code § 2020.
Real example: Marcus, a registered process server in Sacramento County, hands Linda the FL-100 Petition, FL-110 Summons, blank FL-120, and the UCCJEA FL-105 at her workplace lobby at 3:14 p.m. on Tuesday. Marcus checks box 3a on FL-115 and writes the lobby address as the place of service.
A common misconception is that the respondent must accept the papers. They do not. If the respondent refuses, the server may drop the papers at their feet and service is still complete.
Substituted Service Under CCP § 415.20
Substituted service is governed by CCP § 415.20 and is used when the server cannot personally find the respondent after reasonable diligence. The server leaves the papers with a competent adult at the respondent’s home, business, or usual mailing address, then mails a second copy to that address.
The plain-English rule is that you must try personal service two or three times at different times of day before you may pivot to substitute service. The consequence of skipping the diligence step is that the court will quash service on motion under CCP § 418.10, as the appellate court explained in American Express Centurion Bank v. Zara (2011) 199 Cal.App.4th 383.
Real example: Aisha, a process server, tries to find David at his apartment on Monday at 7 p.m., Wednesday at 6 a.m., and Saturday at 1 p.m. On the third try, David’s adult roommate Tony answers. Aisha hands Tony the papers, mails a duplicate set the next day, and attaches a Declaration of Diligence on Form FL-115(D) to her FL-115.
Service is deemed complete on the tenth day after mailing under CCP § 415.20(b). A common misconception is that leaving papers with a minor counts. It does not; the recipient must be at least 18 and apparently in charge.
Service by Mail with Notice and Acknowledgment
This method, found in CCP § 415.30, lets the server mail the papers along with a Notice and Acknowledgment of Receipt, Form FL-117. It only works if the respondent voluntarily signs and returns the FL-117.
The consequence of using this method is that service is not effective until the respondent signs and dates the FL-117. If the respondent ignores the mailing, you have wasted time and must restart with personal or substituted service.
Real example: Jorge mails the petition to his cooperative spouse Elena along with a stamped return envelope and FL-117. Elena signs FL-117 on March 4 and mails it back; Jorge’s server then completes FL-115 box 3b and attaches the signed FL-117.
A common misconception is that certified mail with a green card alone is enough. It is not; California requires the FL-117 acknowledgment, not a postal receipt.
Service by Publication or Posting
When the respondent is truly missing, CCP § 415.50 permits service by publication after a court order on Form FL-980 or FL-982. For low-income filers, Government Code § 6064.5 and the Family Code § 215.5 allow service by posting at the courthouse instead.
The consequence of choosing publication without an order is fatal. Service is void, the default judgment is voidable, and the court may sanction the filer.
Real example: Sandra cannot locate her husband Brian after a year of trying. She files a Declaration of Due Diligence FL-980, gets a court order, publishes for four consecutive weeks in a county-approved newspaper, and then files FL-115 with the publisher’s affidavit attached.
A common misconception is that a Facebook post or text message qualifies as publication. It does not, although California courts have begun to allow electronic service in narrow circumstances after the 2024 amendments to CCP § 1010.6.
Line-by-Line Walkthrough of FL-115
The form has six numbered items on the front and a signature block. Every line matters because the clerk uses them to confirm jurisdiction.
Caption and Case Number
The caption mirrors the FL-100 Petition exactly. Write the petitioner’s full legal name, the respondent’s full legal name, the county and branch of the court, the case number, and the assigned department if known. Mismatched names between FL-100 and FL-115 trigger an automatic clerk rejection because the case-management system cannot match the documents.
The plain-English rule is that you copy and paste from the petition. The consequence of a typo, even a missing middle initial, is that the filing may sit in a clerk’s correction queue for two to three weeks, slowing your six-month waiting period. Real example: Hugo writes “Ana M. Lopez” on FL-100 but “Ana Lopez” on FL-115, and the Los Angeles Superior Court self-help center returns the filing for amendment.
A common misconception is that nicknames or DBA business names are acceptable. They are not; family law requires the legal name as it appears on the marriage certificate or birth certificate.
Item 1: Person Served
Item 1 names the party who was served. In a divorce, this is the respondent named in the FL-100. In a parentage case under the Uniform Parentage Act, Family Code § 7600 et seq., the person served may be the alleged father or mother.
The consequence of misnaming the person served is that the court may treat the wrong individual as having been notified, which voids any default. Real example: in a paternity case, James lists “John Smith Sr.” on FL-115 when the respondent is actually “John Smith Jr.” The default is set aside under CCP § 473(d).
A common misconception is that you can leave Item 1 blank if there is only one respondent. The form still requires the name to confirm identity.
Item 2: Documents Served
Item 2 is a checklist of every document handed over with the Summons. At minimum, you check the FL-100 Petition and FL-110 Summons. Most cases also include the blank FL-120 Response, the FL-105 UCCJEA when minor children are involved, the FL-150 Income and Expense Declaration if support is requested, and any FL-300 Request for Order with attached papers.
The plain-English rule is that you list everything in the envelope. The consequence of forgetting an item is that the unlisted document is deemed unserved, and any orders based on it can be vacated. Real example: Tanya forgets to check FL-105; the resulting custody order is void because the UCCJEA jurisdiction was never established under Family Code § 3424.
A common misconception is that local forms do not need to be listed. They do; check the “Other” box and write them in.
Item 3: Manner of Service
Item 3 is the heart of FL-115. You check exactly one box: 3a for personal service, 3b for mail with FL-117, 3c for substituted service, or 3d for other (publication, posting, or out-of-country service under the Hague Service Convention).
The consequence of checking the wrong box is that the clerk will calendar the response deadline incorrectly, and any default taken on the wrong date is void. Real example: a server mistakenly checks 3a after actually performing substituted service, the response clock starts ten days too early, and the default is reversed under CCP § 473(b).
You also fill in the date, time, and full street address of service. A common misconception is that a P.O. box is acceptable. It is not for personal or substituted service; only physical addresses count.
Item 4: Person Who Served
Item 4 collects the server’s full name, address, telephone number, and registration information if any. Registered California process servers list their county of registration and registration number; sheriffs and marshals list their badge number. Out-of-state servers must qualify under the law of the state where they served and attest to that fact.
The consequence of an incomplete server identity is that opposing counsel can attack service through a motion to quash, and the court must hold an evidentiary hearing under CCP § 418.10. Real example: Diego serves papers in Nevada but forgets to cite Nevada’s service statute, NRS 14.090, and the California court strikes the proof.
A common misconception is that the server’s home address can be omitted for privacy. It cannot, although registered process servers may use their registered business address.
Item 5: Fee for Service
Item 5 lists the dollar amount charged for service. Sheriffs typically charge forty dollars or so per Government Code § 26721; private servers charge anywhere from sixty to two hundred dollars depending on county.
The consequence of leaving Item 5 blank is minor for the validity of service but matters for fee recovery. Under Family Code § 2030, service costs can be charged to the higher-earning spouse, but only if documented on FL-115.
A common misconception is that pro bono service still requires a fee entry. Write “0” or “none” rather than leaving it blank.
Item 6 and Signature
Item 6 contains the server’s declaration under penalty of perjury under CCP § 2015.5. The server signs, dates, and prints their name. Registered process servers check the box stating they are exempt from registration if applicable.
The consequence of an unsigned FL-115 is fatal. The clerk treats it as no proof at all and rejects the filing. Real example: Olivia, a friend who served papers, forgets to sign; the Alameda County clerk returns the form, and Olivia’s friend must restart the response calendar.
A common misconception is that a digital signature is invalid. California accepts electronic signatures under CCP § 1010.6 and California Rules of Court, Rule 2.257.
Three Real-World Service Scenarios
Below are three of the most common fact patterns and the FL-115 outcome for each.
Scenario 1: Cooperative Spouse, Mail Service
| Step Taken by Server | Result on FL-115 |
|---|---|
| Mails petition packet plus FL-117 to spouse’s home | Box 3b checked, address listed |
| Spouse signs FL-117 and returns it within two weeks | FL-117 stapled as attachment to FL-115 |
| Server signs FL-115 under penalty of perjury | Service deemed complete on signature date |
Scenario 2: Evasive Spouse, Substituted Service
| Step Taken by Server | Result on FL-115 |
|---|---|
| Three personal-service attempts logged with dates and times | Declaration of Diligence FL-115(D) attached |
| Papers left with adult son at home, copy mailed next day | Box 3c checked, son’s name listed |
| Service deemed complete ten days after mailing | Default available 30 days after that date |
Scenario 3: Missing Spouse, Service by Publication
| Step Taken by Server | Result on FL-115 |
|---|---|
| Filer obtains court order on FL-982 after diligent search | Order attached to FL-115 |
| Newspaper publishes summons four consecutive weeks | Publisher’s affidavit attached |
| Service deemed complete 28 days after first publication | Box 3d checked, “Publication per § 415.50” written in |
Special Service Situations
Some respondents trigger extra federal or state rules that change how you complete FL-115.
Military Spouses
Active-duty military respondents are protected by the Servicemembers Civil Relief Act, 50 U.S.C. § 3931. If the respondent does not appear, you must file a Servicemember Status Declaration through the DMDC SCRA website before any default. The consequence of skipping this is that the default judgment can be reopened up to 90 days after discharge.
A real example: Captain Reyes is deployed to Germany when his spouse files for divorce. Service is made by personal delivery on base through the chain of command, and FL-115 includes the SCRA declaration. A common misconception is that service on base is impossible; it is not, but it requires coordination with the Staff Judge Advocate.
Incarcerated Respondents
When the respondent is in a California Department of Corrections facility, service is made through the warden under Penal Code § 4013. The server lists the facility address and the warden’s office on FL-115.
The consequence of mailing directly to an inmate without warden involvement is that prison mailroom rules may delay or refuse delivery, and service is not effective. Real example: Carla mails papers to her husband at Folsom State Prison without going through the warden, and the mailroom returns them.
Out-of-State and Overseas Respondents
For out-of-state respondents, CCP § 415.40 authorizes service by certified mail, return receipt requested. For respondents in countries that signed the Hague Service Convention, service must follow the Convention’s central authority procedure, often through the U.S. Department of State.
The consequence of bypassing the Hague Convention when it applies is that the entire judgment can be unenforceable abroad, which matters for spousal support collection across borders. A common misconception is that emailing papers to a respondent in France is enough; France has objected to Article 10 alternative methods, so it is not.
Mistakes to Avoid on FL-115
Avoid these errors, which appear repeatedly in California Courts Self-Help Center data and county clerk reject reports.
- Filing FL-115 signed by the petitioner, which voids service under CCP § 414.10 and forces a complete restart.
- Checking Box 3a personal service when the server actually used substituted service, which miscalculates the response deadline and exposes the default to reversal.
- Forgetting to attach the Declaration of Diligence FL-115(D) for substituted service, which lets the respondent quash service on motion.
- Listing a P.O. box as the place of personal service, which violates CCP § 415.10 and triggers an automatic clerk rejection.
- Failing to include a date and exact time of service, which prevents the clerk from calendaring the 30-day response window required by Family Code § 2020.
- Skipping FL-105 when the case involves children, which leaves the court without UCCJEA jurisdiction under Family Code § 3424.
- Using mail service through FL-117 without waiting for the respondent’s signature, which means service is never effective and the default request will be rejected.
- Omitting the registered process server’s county and registration number, which violates Business and Professions Code § 22350.
- Filing FL-115 before all attachments are stapled, which causes clerks to separate the documents and lose them in the case file.
- Trying to serve by social media without a court order under CCP § 1010.6, which the court will reject as unauthorized.
Do’s and Don’ts of Filing FL-115
The following list keeps your filing on track and your case moving toward a default or response.
- Do hire a registered California process server when the respondent is hostile, because their declarations carry a presumption of validity under Evidence Code § 647.
- Do attach the FL-115(D) Declaration of Diligence anytime substituted service is used, because Rule 5.68 requires proof that personal service was reasonably attempted.
- Do double-check that the case caption matches the FL-100 word for word, because mismatched captions cause clerk rejections that delay the six-month waiting period under Family Code § 2339.
- Do file the original FL-115 with the court and serve no one with the original, because the clerk needs the wet or e-filed signature for the case file.
- Do calendar the response deadline using the Judicial Council Online Calculator to avoid premature default requests.
- Don’t let the petitioner sign FL-115, because CCP § 414.10 forbids parties from serving their own papers.
- Don’t use ordinary first-class mail without FL-117, because California family law does not recognize bare-mail service for the initial summons.
- Don’t backdate or postdate the service date, because false declarations under penalty of perjury can lead to prosecution under Penal Code § 118.
- Don’t assume actual knowledge cures defective service, because California appellate courts uniformly hold that strict statutory compliance is required.
- Don’t file FL-115 before service is actually complete, because premature filings are routinely rejected and waste filing slots.
Pros and Cons of Each Service Method
The right service method depends on cooperation level, location, and budget.
- Pro of personal service: It is the fastest and most defensible method, since the response clock starts the same day under CCP § 415.10.
- Pro of mail with FL-117: It is the cheapest method when the respondent is cooperative, often costing only the price of postage.
- Pro of substituted service: It works when the respondent is dodging, since CCP § 415.20 allows leaving papers with another adult.
- Pro of publication: It is the only path forward when the respondent is truly missing, preserving the petitioner’s right to a divorce under Family Code § 2320.
- Pro of sheriff service: Sheriff service produces an officer’s return that judges trust on its face.
- Con of personal service: It can be expensive and emotionally charged when the respondent is volatile.
- Con of mail with FL-117: Service fails entirely if the respondent ignores the envelope, wasting two to three weeks.
- Con of substituted service: It requires a declaration of diligence and adds at least ten days to the timeline.
- Con of publication: It is slow, costs newspaper fees, and limits the relief available to status only, with no money judgment under CCP § 415.50.
- Con of sheriff service: Sheriffs often have backlogs of two to four weeks in busy counties like Los Angeles and San Diego.
Comparison of California Service Methods
| Method and Statute | Cost Range | Effective Date | Best Use |
|---|---|---|---|
| Personal under CCP § 415.10 | $40-$200 | Day of delivery | Hostile or unresponsive spouse |
| Mail + FL-117 under CCP § 415.30 | Postage only | Date FL-117 signed | Cooperative spouse |
| Substituted under CCP § 415.20 | $75-$250 | 10 days after mailing | Evasive spouse, known address |
| Publication under CCP § 415.50 | $200-$800 | 28 days after first run | Missing spouse, status only |
Key Court Rulings That Shape FL-115 Practice
Several California decisions interpret service rules in ways every filer should know. In Sakaguchi v. Sakaguchi (2009) 173 Cal.App.4th 852, the Second District held that service performed by a party is void on its face. In American Express Centurion Bank v. Zara (2011) 199 Cal.App.4th 383, the court explained that two or three good-faith attempts at personal service are required before substituted service is allowed.
The federal due-process foundation comes from Mullane v. Central Hanover Bank & Trust Co. (1950) 339 U.S. 306, which California courts apply to ensure notice is reasonably calculated to reach the respondent. In In re Marriage of Smith (2015) 242 Cal.App.4th 529, the court reiterated that strict compliance with service statutes is required even between formerly married parties.
The plain-English takeaway is that judges will not bend the service rules to reach a fair-feeling result. Real example: Veronica’s default judgment against Pedro is reversed twelve months later because the substituted service papers were left with a 16-year-old, not an adult.
County-Specific Filing Tips
California’s 58 counties each layer their own local rules on top of the statewide form. The Los Angeles Superior Court Local Rules, Chapter 5 require an additional cover sheet, while the San Diego Superior Court requires e-filing through One Legal or Odyssey. The San Francisco Superior Court charges a separate clerk’s certification fee on top of the statewide $435 dissolution filing fee.
The consequence of ignoring local rules is that the clerk rejects the FL-115 even when the form itself is correct. A common misconception is that statewide forms override local rules. They do not; both must be followed.
The Alameda County, Orange County, and Sacramento County self-help websites publish updated FL-115 cheat sheets that walk filers through county-specific quirks like courtesy copies and e-filing portals.
FAQs
Can I serve my spouse the divorce papers myself?
No. Under CCP § 414.10, no party may serve their own papers, so any FL-115 you sign as the petitioner is void on its face.
Is FL-115 the same as POS-010?
No. POS-010 is for general civil cases, while FL-115 is the family-law-specific Proof of Service of Summons required by Rule 5.68 of the California Rules of Court.
Can I serve my spouse by email or text message?
No. Initial service in family law still requires statutory methods, although the court may authorize electronic service in limited circumstances under CCP § 1010.6 after appearance.
Do I need to file FL-115 even if my spouse signs the petition?
Yes. Even when both parties cooperate, the court still needs FL-115 with FL-117 attached to confirm jurisdiction under CCP § 415.30.
Is substituted service available on the first attempt?
No. CCP § 415.20 and case law require reasonable diligence, meaning two or three personal-service attempts at varied times before substituted service is permitted.
Can a process server serve papers at a workplace?
Yes. Workplaces are valid service locations under CCP § 415.20(b), provided the server leaves the papers with a person apparently in charge if the respondent is unavailable.
Does FL-115 need to be notarized?
No. It is signed under penalty of perjury per CCP § 2015.5, so a notary stamp is not required and adds no legal weight.
Can my adult child serve the papers?
Yes. Anyone 18 or older who is not a party may serve under CCP § 414.10, including adult children, friends, and roommates.
Is there a fee waiver for service costs?
Yes. Low-income filers may request waiver of sheriff service fees through Form FW-001 under Government Code § 68631.
Can I file FL-115 electronically?
Yes. Most California counties now accept electronic filing through One Legal or File & ServeXpress, and digital signatures are valid under Rule 2.257.
Can my spouse waive service?
Yes. A signed FL-117 Notice and Acknowledgment of Receipt operates as a waiver of formal service under CCP § 415.30.
Does service of FL-115 trigger the six-month waiting period?
Yes. The clock under Family Code § 2339 starts the day service is completed, which is the date entered on FL-115.
