Yes, you can fill out California Form FL-911 yourself, and doing it correctly protects your family law case from delays, sanctions, and dismissal. Form FL-911 is the Notice of Related Case used in California family law to alert the court that another case involving the same parties, children, or property is pending or has been decided. You file it with the California Superior Court so judges can coordinate rulings and avoid conflicting orders.
Missing or incorrect FL-911 filings cause real harm. According to the California Courts self-help center, more than 70% of family law filers represent themselves, and procedural errors on related-case notices are a top reason cases get continued, transferred, or stalled in the California Judicial Council forms library.

What Form FL-911 Is and Why It Exists
California Form FL-911 is the Notice of Related Case used in family law proceedings such as dissolution, legal separation, parentage, child custody, child support, and domestic violence restraining orders. The form tells the court that another case in any California county, federal court, or out-of-state tribunal involves the same parties, children, real property, or community assets. Judges use this notice to decide whether to consolidate, transfer, stay, or coordinate the cases under California Rules of Court 3.300 and the family-law parallel rule.
The plain-English purpose is simple. When two or more cases overlap, conflicting orders can hurt children and waste court time. The consequence of failing to file FL-911 when a related case exists is severe: a judge can vacate orders, sanction the filer under Code of Civil Procedure § 128.7, or transfer the case sua sponte. A common misconception is that only attorneys must file this notice, but every party, including pro per litigants, has a continuing duty to disclose related cases as soon as they learn of them.
Federal Background and California Adoption
Federal courts have long required related-case notices through Federal Rule of Civil Procedure 42, which authorizes consolidation. California adopted similar coordination tools in the 1970s and refined them for family law in the 2000s when the Elkins Family Law Task Force urged uniform statewide forms. The Judicial Council then created FL-911 to standardize the disclosure across all 58 counties, replacing dozens of inconsistent local forms used previously by courts like the Los Angeles Superior Court and the San Diego Superior Court.
The consequence of skipping the federal-style coordination step is that conflicting custody orders may issue from two California counties at once. A real-world example involves a mother who filed for divorce in Sacramento while a juvenile dependency case was pending in Fresno; without FL-911, both courts issued conflicting custody orders. A common misconception is that a juvenile dependency case is too confidential to disclose, but the form specifically allows reference to confidential cases by case number only.
Statutory Authority Under California Law
The driving statute is Family Code § 2330, which controls dissolution petitions, paired with Family Code § 215 on continuing jurisdiction. Procedurally, the California Rules of Court 5.500 tells filers how and when to lodge FL-911. The plain-English meaning is that you must tell the court about overlapping cases at the start and update the notice whenever you learn of a new one.
The consequence of ignoring this statute is that any judgment can later be challenged as void for lack of coordinated jurisdiction. A real-world example: a father in Riverside obtained a custody order, only to have it vacated when the court learned a parentage case had been pending in Orange County. A common misconception is that small claims, probate, or guardianship cases do not count, but any case touching the same children, property, or parties is reportable.
Line-By-Line Walkthrough of Form FL-911
The current FL-911 published on the Judicial Council forms page has a caption block, six numbered sections, and a signature line. Each box has its own rule. Filling in the form correctly takes about 15 minutes if you have the related case numbers ready. Filling it out wrong can cost months.
Top Caption: Attorney or Party Without Attorney
The very top of FL-911 mirrors every other Judicial Council family law form. You enter your full legal name, mailing address, telephone number, fax (if any), and email under the rules of California Rules of Court 2.111. Pro per filers must write In Pro Per or Self-Represented in the attorney bar number space.
The consequence of putting a wrong address here is that the court will mail orders to the wrong place and you will miss hearings. A real-world example: Maria, a self-represented petitioner in Alameda County, wrote her old address on FL-911 and missed a custody hearing because the notice went to her former apartment. A common misconception is that you can use a friend’s address for privacy, but Family Code § 6380.5 and the Safe at Home program provide the only proper confidentiality channel.
Court Branch and Case Caption
Below the attorney block, you list the Superior Court of California, County of ____, the branch address, and the case caption: Petitioner, Respondent, Other Parent or Other Party. The case number is mandatory. The plain-English rule is that this caption must match the exact caption on your underlying petition, including punctuation, as required by Rule of Court 2.100.
The consequence of mismatched captions is rejection at the clerk’s window or e-filing portal. A real-world example: David filed FL-911 listing himself as Petitioner when the underlying case had him as Respondent; the clerk rejected the filing and the related case continued without coordination for two months. A common misconception is that minor typos are forgiven, but California’s TrueFiling system and county portals reject mismatched captions automatically.
Section 1: Title of Related Case
Section 1 asks for the title of the related case exactly as it appears on the other case’s caption. You write In re the Marriage of Smith and Jones or People v. Smith depending on the matter. The plain-English rule is to copy the title verbatim from the other case’s first-page caption.
The consequence of paraphrasing is that the court cannot find the related file. A real-world example: Priya wrote Custody case for my son instead of Patel v. Patel and the clerk could not match the file. A common misconception is that you should describe the case in your own words; you should not, because the court’s case management system searches on exact titles.
Section 2: Case Number
Section 2 demands the full case number of the related case, including any letter prefixes used by the county. Los Angeles uses prefixes like BD, PD, or 24STFL; San Francisco uses FDI and FDV. The plain-English rule is to copy the entire string from the other case’s caption.
The consequence of an incomplete case number is that the court cannot pull the related file electronically. A real-world example: Jamal omitted the 24STFL prefix on a Los Angeles dissolution and the Stanley Mosk clerk could not locate the related DVRO. A common misconception is that the numerical part alone is enough, but LA Superior Court local rules require the full alphanumeric string.
Section 3: Court and Branch
Section 3 asks for the court name and branch address of the related case. You write Superior Court of California, County of Orange, Lamoreaux Justice Center, for example. The plain-English rule is to identify the specific courthouse, not just the county, because many counties have multiple branches.
The consequence of writing only the county is that the file may sit at the wrong courthouse for weeks. A real-world example: Sofia listed San Bernardino without naming the Victorville branch, and her DVRO file sat in the central courthouse 80 miles away. A common misconception is that all family files live in one central building, but the San Bernardino Superior Court operates four family branches.
Section 4: Department and Judge
Section 4 asks for the department number and assigned judicial officer in the related case. You write Dept. F-401, Hon. Jane Doe. The plain-English rule is to look at the most recent minute order from the other case to confirm the current department.
The consequence of naming the wrong judge is judicial confusion and possible recusal motions. A real-world example: Marcus listed a retired judge, prompting a 30-day delay while the new bench officer reviewed the file. A common misconception is that any judge in the building can hear the related case, but the one-family/one-judge rule under California Rules of Court 5.107 keeps a single judge on the family.
Section 5: Case Status and Type
Section 5 requires you to check whether the related case is pending, dismissed, resolved by judgment, or on appeal, and to identify the type, such as dissolution, parentage, juvenile, criminal, civil, or probate. The plain-English rule is to check every box that applies and provide the most recent disposition date.
The consequence of guessing the status is that the court may rely on stale information. A real-world example: Elena marked a juvenile case as closed when reunification services were still active, leading to a custody order that conflicted with the dependency court. A common misconception is that a temporary stay equals dismissal, but a stay is still pending under Code of Civil Procedure § 916.
Section 6: How the Cases Are Related
Section 6 is the heart of FL-911. You explain in plain language how the two cases involve the same parties, children, property, transactions, or legal questions. The plain-English rule is to write two or three short sentences, naming the children by initials, the parties by full name, and the assets by general description.
The consequence of a vague explanation is that the judge may decline to coordinate. A real-world example: Tomás wrote Same family, which the court found insufficient and required an amended FL-911. A common misconception is that brevity is best, but the form expressly invites detail and Rule 5.500(c) requires enough facts to allow informed coordination.
Signature, Date, and Declaration Under Penalty of Perjury
The bottom of FL-911 includes a declaration under penalty of perjury under the laws of California, dated and signed by the filer. The plain-English rule is that you must sign personally, in ink or with a conformed electronic signature, and date it the day you sign.
The consequence of an unsigned or undated FL-911 is rejection and possible perjury exposure if you later sign falsely. A real-world example: Aiyana forgot to date her form, and the clerk rejected it; she then backdated it, which is a misdemeanor under Penal Code § 118. A common misconception is that a typed name suffices on a paper filing, but California requires either ink or a court-approved e-signature.
Three Real-World Scenarios
These scenarios show how FL-911 works in everyday family law cases. Each table maps the filer’s Filing Step to the resulting Court Action under California rules.
Scenario 1: Divorce With Pending Domestic Violence Case
Lin files for dissolution in Santa Clara while a DVRO under DV-100 is pending in the same county. She must file FL-911 to alert the family judge to the DVRO so custody and support orders stay aligned. The court coordinates both files under one judicial officer.
| Filing Step | Court Action |
|---|---|
| Lin files FL-100 dissolution petition | Case opened, judge assigned |
| Lin files FL-911 listing DV case number | Files transferred to one department |
| Lin attends combined hearing | Coordinated custody and DVRO orders issued |
Scenario 2: Parentage Case With Out-of-County Custody Action
Devon filed a parentage case in San Diego, then learned the mother filed for custody in Imperial County. He must file FL-911 in both counties so judges can decide whether to transfer one case under Code of Civil Procedure § 397.
| Filing Step | Court Action |
|---|---|
| Devon files FL-911 in San Diego | Judge sets coordination hearing |
| Devon files FL-911 in Imperial | Judge contacts San Diego court |
| Both judges confer under UCCJEA | Case venue decided in 30 days |
Scenario 3: Probate and Family Law Overlap
Yumi is divorcing while a probate case for her deceased father-in-law is pending, involving community property. She files FL-911 to alert the family court to the probate inventory so asset division stays consistent under Probate Code § 850.
| Filing Step | Court Action |
|---|---|
| Yumi files FL-911 naming probate case | Family judge orders joint asset list |
| Probate court receives notice copy | Probate judge stays asset transfers |
| Joint status conference held | Property division coordinated |
Three Named Examples in Action
These examples show how named individuals use FL-911 to protect their rights. Each illustrates a different procedural angle that real California filers face every day.
Example 1: Carmen and the Cross-County DVRO
Carmen lives in Kern County but obtained a DVRO in Tulare County after fleeing there. When she later filed for divorce in Kern, she completed FL-911 listing the Tulare DVRO under case number VFL12345 and attached a copy of the protective order. The Kern judge then conferred with Tulare under Family Code § 6383 and issued matching no-contact terms.
The consequence of not filing FL-911 would have been conflicting visitation orders. The plain-English lesson is that even cases in different counties must be disclosed. A common misconception is that a DVRO automatically transfers to the divorce court, but it does not without notice and an order.
Example 2: Hassan and the Juvenile Dependency Overlap
Hassan filed a custody petition in Contra Costa while his children were in juvenile dependency under Welfare and Institutions Code § 300. He filed FL-911 disclosing the dependency case number, which triggered an automatic stay of the family case under Family Code § 3010.
The consequence of not disclosing was potential contempt for interfering with juvenile jurisdiction. The plain-English lesson is that juvenile cases trump family cases on custody. A common misconception is that confidentiality bars disclosure, but the case number alone is sufficient and not confidential.
Example 3: Renée and the Multistate Move
Renée moved from Nevada to California and learned her ex filed a custody modification in Las Vegas. She filed FL-911 in Sacramento listing the Nevada case, prompting a UCCJEA conference under Family Code § 3410. The judges agreed Nevada retained jurisdiction.
The consequence of not filing FL-911 would have been parallel proceedings and conflicting orders. The plain-English lesson is that out-of-state cases count. A common misconception is that FL-911 only covers California cases, but the form expressly accepts cases from other jurisdictions.
Mistakes to Avoid on Form FL-911
Self-represented filers make the same errors over and over. Each mistake below carries a specific consequence and a fix you can apply today.
- Leaving Section 6 blank or vague causes the judge to ignore the notice; write at least two sentences naming the parties and overlap.
- Using the wrong case number prevents the clerk from pulling the related file; copy the full alphanumeric string from the other case caption.
- Forgetting to update FL-911 when a new related case starts violates Rule 5.500; file an amended FL-911 within 15 days of learning of the case.
- Not serving FL-911 on the other party means the court cannot rely on it; serve by mail and file proof on Form FL-335.
- Listing the wrong department delays coordination; check the most recent minute order or the court’s online case index.
- Backdating the signature violates Penal Code § 118; always sign and date on the same day.
- Omitting juvenile or probate cases breaks the disclosure rule; every overlapping case counts, including small claims with shared property.
- Filing FL-911 only in one county when cases span multiple counties leaves the other court uninformed; file in every relevant superior court.
- Mismatching the caption triggers automatic e-filing rejection; copy the caption letter-for-letter from your petition.
- Confusing FL-911 with the civil Form CM-015 causes the wrong form to be filed; FL-911 is for family law only.
Do’s and Don’ts for Filing FL-911
These practical do’s and don’ts come from years of family courthouse practice. Each one ties to a specific California rule or statute.
Do’s
- Do file FL-911 with your initial petition whenever a related case already exists, because Rule 5.500 requires immediate disclosure.
- Do serve every party in every related case, because due process demands notice under Code of Civil Procedure § 1005.
- Do keep a stamped copy in your case file, because clerks lose filings and you may need to prove timely service.
- Do update the form every time you learn of a new case, because the duty is continuing under Family Code § 215.
- Do attach copies of key orders from the related case, because judges often want context before coordinating.
- Do use TrueFiling or your county’s e-filing portal where mandatory, because paper filings are rejected in many counties.
Don’ts
- Don’t skip FL-911 because the related case is closed, because closed cases with active enforcement still affect jurisdiction.
- Don’t paraphrase case titles, because the court’s database searches on exact strings.
- Don’t hide juvenile cases for privacy, because case numbers alone are not confidential.
- Don’t sign without reading the perjury declaration, because false statements expose you to misdemeanor charges.
- Don’t assume your attorney filed it, because every party has an independent duty to disclose.
- Don’t file FL-911 in lieu of a Request for Order on Form FL-300; FL-911 is a notice, not a request for relief.
Pros and Cons of Filing FL-911 Yourself
Filing FL-911 pro per saves money but carries risk. Weigh both sides before deciding.
Pros
- Cost savings of $300 to $800 in attorney drafting fees, because the form is short and free on the Judicial Council site.
- Speed because you can file the same day you learn of the related case, beating attorney scheduling delays.
- Empowerment because completing FL-911 helps you understand your own case and the related proceedings.
- Court approval because California’s self-help policy actively supports pro per filers.
- Transparency because filing puts both judges on notice and reduces the risk of conflicting orders.
Cons
- Legal risk because mistakes can lead to sanctions or vacated orders under Code of Civil Procedure § 128.7.
- Strategic blind spots because non-lawyers may not see how a related case affects custody, support, or property division.
- Time cost because gathering case numbers and serving parties takes hours.
- Emotional burden because reviewing related cases, especially DVROs and dependency files, can be retraumatizing.
- Local rule traps because each county has its own e-filing quirks the form does not warn you about.
Filing, Serving, and Updating FL-911
Filing the form is only step one. You must serve every party in every related case and file proof of service. The plain-English process is: complete, copy, file, serve, prove.
The consequence of skipping service is that the court may treat FL-911 as not filed for coordination purposes. A real-world example: Brendan filed FL-911 but never served the other parent, and the judge declined to coordinate at the next hearing. A common misconception is that the clerk serves the form, but in California family law the filer is responsible for service under Rule 5.500(d).
Service Methods Allowed
You may serve by personal delivery, first-class mail, or electronic service under Code of Civil Procedure § 1010.6 if the other party has consented. Personal service is required if the related case involves a DVRO with no-contact terms.
The consequence of using the wrong method is invalid service and a wasted filing. A real-world example: Olivia emailed FL-911 to her ex without prior e-service consent; the court struck the proof. A common misconception is that text messages count as service; they do not.
Continuing Duty to Update
Your duty does not end at filing. If a new related case opens or an existing one closes, you must file an amended FL-911 within a reasonable time, generally 15 days under local rules like San Francisco Local Rule 11.
The consequence of failing to update is that the court relies on stale information and may issue conflicting orders. A real-world example: Kenji’s juvenile case closed but he never updated FL-911, so the family court continued to defer to a no-longer-active dependency stay. A common misconception is that one filing covers the life of the case, but the duty is continuing.
Key Entities You Should Know
Several people, courts, and concepts shape how FL-911 works in California. Knowing each role helps you fill out the form accurately.
The Judicial Council of California drafts and publishes FL-911 and every other family law form. The California Department of Child Support Services is often a related-case party in support matters. Local Family Law Facilitators provide free help completing FL-911 in every county. The Center for Families, Children & the Courts issues guidance on coordination of overlapping family cases.
Court Rulings Worth Remembering
California appellate courts have repeatedly stressed the importance of related-case notices. In In re Marriage of Carlsson (2008) 163 Cal.App.4th 281, the court reversed a judgment partly because related proceedings were not properly coordinated. In In re Chantal S. (1996) 13 Cal.4th 196, the California Supreme Court emphasized the primacy of juvenile dependency jurisdiction over family law custody, a rule directly enforced through FL-911 disclosures.
The consequence of ignoring these rulings is that orders entered without coordination may be vacated on appeal. A plain-English takeaway is that judges expect full disclosure and will reverse when it is missing. A common misconception is that appellate cases do not affect form filings, but they shape how trial judges read FL-911 every day.
FAQs
Is FL-911 mandatory in every California family law case?
No. FL-911 is mandatory only when a related case exists. If there is no overlapping case involving the same parties, children, or property, you do not file the form.
Do I file FL-911 in juvenile dependency cases?
Yes. When a family law case overlaps with a juvenile dependency matter under Welfare and Institutions Code § 300, you must disclose the dependency by case number on FL-911.
Can I use FL-911 to ask the judge for orders?
No. FL-911 is a notice, not a request. To ask for orders you must use Form FL-300, the Request for Order, with proper supporting declarations.
Does FL-911 apply to out-of-state cases?
Yes. The form expressly accepts cases from other states and federal courts, especially under the Uniform Child Custody Jurisdiction and Enforcement Act in Family Code § 3400 et seq.
Is there a filing fee for FL-911?
No. Filing FL-911 is free in California family law cases because it is a notice ancillary to the main petition for which fees are already paid or waived.
Can a Legal Document Assistant fill out FL-911 for me?
Yes. A registered LDA under Business & Professions Code § 6400 may type your answers, but the LDA cannot give legal advice or choose what to disclose.
Will the court reject FL-911 for small typos?
Yes. Many county e-filing systems automatically reject filings with mismatched captions or missing case numbers, so accuracy is essential.
Do I need to serve FL-911 on the other party?
Yes. You must serve every party in your case and in the related case, then file a proof of service such as Form FL-335.
Can I file FL-911 electronically?
Yes. Most California superior courts accept e-filing through TrueFiling, File & ServeXpress, or county-specific portals, and many counties require it.
Does FL-911 cover criminal cases involving the same parties?
Yes. Criminal protective orders and pending criminal matters that affect custody or contact must be disclosed on FL-911 to keep family orders consistent.
Can I be sanctioned for filing a false FL-911?
Yes. False statements expose you to perjury under Penal Code § 118 and monetary sanctions under Code of Civil Procedure § 128.7.
Is FL-911 the same as a Notice of Related Case in civil court?
No. Civil cases use Form CM-015 under Rule 3.300, while family law uses FL-911 under Rule 5.500, and the two forms are not interchangeable.
