Filing California Form FL-235, the Child Support Case Registry Form, requires entering your case information, party identifiers, contact details, employer data, and health insurance facts so the California Department of Child Support Services can track and enforce your support order. You file this form every time the court enters or changes a child support, family support, or spousal support order, and you must update it within 10 days of any change to your address, employer, or contact information under Family Code § 4014.
The federal Title IV-D program requires every state to maintain a centralized case registry, and California enforces that mandate through FL-235. According to the federal Office of Child Support Services, the program collected over $32 billion in support nationwide in fiscal year 2024, and accurate registry data drove most of those collections.

What Form FL-235 Is and Why It Exists
California Form FL-235 is the Child Support Case Registry Form published by the Judicial Council of California. Every parent or party in a case that involves child support, family support, or spousal support must file it the first time the court enters an order, and again whenever key information changes. The form feeds data into the California Child Support Automated System (CCSAS), which links every county and the federal registry.
The form replaced the older FL-191, which California retired when it streamlined registry intake in the early 2010s. Today, FL-235 captures the same core data but adds employer detail and health insurance fields. Filing FL-235 is mandatory under Family Code § 4014, which directs the parties to provide the registry information at the time of the order.
The plain-English point is simple. The state needs to know who you are, where you live, where you work, and who insures the kids, so it can collect or send support and update records fast. The consequence of skipping the form is real. A court can find you in contempt, enter sanctions, or refuse to accept your judgment until you cure the filing.
A common misconception is that only the parent paying support must file FL-235. That is wrong. Both parents file separate FL-235 forms in every support case. The form is private and is not served on the other party, which protects victims of domestic violence under Family Code § 6200.
When You Must File FL-235
You file FL-235 with the clerk at three trigger points. The first trigger is the entry of any new support order, including a stipulated judgment. The second trigger is any modification of an existing order. The third trigger is any change to the data on the form, such as a new job, new address, or new health plan, within 10 days of the change.
Filing late or skipping a trigger creates direct consequences. The Local Child Support Agency (LCSA) loses your address, your wage assignment may go to the wrong employer, and you may miss notice of a contempt or arrears action. A real example: Carlos, a father in Sacramento, switched jobs and waited three months to update FL-235. His old employer stopped withholding, his arrears grew by $2,400, and the LCSA filed a contempt motion that he had to defend on his own.
A common misconception is that telling the Department of Child Support Services about the change is enough. It is not. The court file is separate from the DCSS file, and you must update both with a fresh FL-235.
Statutory and Federal Basis
Family Code § 4014 is the operative California statute. It compels parties to provide registry data at the time the court issues a support order. The federal companion is 42 U.S.C. § 654a, which forces every state to run a centralized case registry under penalty of losing federal Title IV-D funds.
The consequence of California failing to comply at the state level is loss of federal match dollars, which the federal Office of Child Support Services tracks each quarter. The consequence at the personal level is that your order is unenforceable across state lines without registry data. A common misconception is that the registry data is public. It is not. Family Code § 17212 imposes confidentiality, and unauthorized disclosure is a misdemeanor.
Step-by-Step: How to Fill Out FL-235
The form is one page with numbered sections. Work top to bottom and use black or blue ink, or type the entries through the fillable PDF. Print one original for the court file and keep one copy for your records.
Caption and Case Number
The caption is the box at the top. You enter your name, address, telephone number, email, and your role, such as petitioner, respondent, or attorney. The case caption mirrors the caption on your FL-100 petition or FL-300 RFO, so copy it exactly.
The consequence of a mismatched caption is that the clerk rejects the filing under California Rules of Court, Rule 2.100. A real example: Priya, a mother in San Diego, listed her married name on FL-100 but her maiden name on FL-235. The clerk bounced the form, and her wage assignment took 14 extra days to issue.
A common misconception is that you can leave the case number blank if the case is brand new. You cannot. If the case is so new that no number has been assigned, you file FL-235 the same day the clerk stamps the case number on your petition.
Section 1: Type of Action
Section 1 asks whether the case involves a court order or a Title IV-D case opened through the LCSA. Check every box that applies. If your case has both a private order and an LCSA case, check both.
The consequence of misidentifying the case type is that the registry routes your data to the wrong queue. A real example: Marcus, a father in Alameda County, marked only “child support” when his case also included spousal support. The state registry never coded the spousal piece, and his employer withheld $300 too little each month for six months.
A common misconception is that “family support” means anything family-related. It does not. Family support is a specific tax-advantaged label combining child and spousal support into one undifferentiated payment under IRC § 71 (pre-2019 orders) and current state practice.
Section 2: Court Order Information
Section 2 captures the date the order was filed, the county, the type of order, and whether the order is new, modified, or terminated. Pull the dates straight from the conformed copy of your FL-340 findings and order or your judgment.
The consequence of a wrong date is that the registry shows a stale order, and any wage assignment under FL-195 may be voided by the employer. A real example: Jennifer, a mother in Fresno, transposed the order date from 03/14/2026 to 03/04/2026. Her ex-husband’s employer rejected the income withholding order because the dates did not match the court’s index.
A common misconception is that you only complete this section once. You complete it again every time the court issues a modification, even a stipulated bump of $50 per month.
Section 3: Children Covered by the Order
Section 3 lists each child by full legal name, date of birth, and Social Security number. The form requires the SSN under 42 U.S.C. § 666(a)(13), and California protects it under Family Code § 17212.
The consequence of leaving the SSN blank is that the LCSA cannot match the child to Medi-Cal, CalWORKs, or federal tax intercept under the Treasury Offset Program. A real example: Ben, a stepfather adopting two children in Riverside, omitted the new SSNs because the post-adoption cards had not arrived. His tax intercept on the biological father’s refund missed the April cycle, costing $1,800 in delayed arrears recovery.
A common misconception is that you can list a child not covered by the order to ease future modifications. You cannot. List only the children named in the current order, and add others through a separate request to modify.
Section 4: Parties to the Order
Section 4 captures each party’s name, date of birth, SSN, driver’s license number, mailing address, residence address, telephone, and email. You also list the same fields for any new spouse only if state law requires garnishment from community property, which California rarely does without a separate court order.
The consequence of an inaccurate address is that the Sheriff or registered process server cannot serve enforcement papers, and the LCSA may default to the last address in the registry. A real example: Aisha, a mother in Oakland, moved twice in 2025 without updating FL-235. Her ex’s wage assignment forms went to her old apartment, the checks bounced back, and her support paused for two pay cycles.
A common misconception is that the residence address is published in the public file. It is not. The residence address is held in the confidential registry under Family Code § 17212, separate from the public court file.
Section 5: Employer Information
Section 5 asks for the name, address, telephone number, and (optionally) FEIN of the obligor’s employer, plus the obligor’s job title and start date. If you are self-employed, you list your business name and EIN. If you are unemployed, you write “unemployed” and list the date of last employment.
The consequence of leaving employer fields blank is that no Earnings Assignment Order (FL-195) can issue, and the obligee must collect by other means. A real example: David, a self-employed contractor in Long Beach, wrote “self-employed” without his EIN. The LCSA could not run a Financial Institution Data Match, and a $9,000 arrears balance sat untouched for nine months.
A common misconception is that gig workers and 1099 contractors do not have to disclose income. They do. The California Employment Development Department requires reporting of independent contractor payments, and FL-235 captures the payer for the same purpose.
Section 6: Health Insurance Information
Section 6 captures the name of the health insurance company, policy number, group number, and the name of the policyholder for each child. If you do not have insurance, you write “none.” If insurance is available through your employer at reasonable cost under Family Code § 3751, you may still be ordered to enroll.
The consequence of false insurance data is that the court may issue a Qualified Medical Child Support Order (QMCSO) that the plan rejects. A real example: Linda, a mother in San Jose, listed her old Kaiser policy that lapsed when she changed employers. The QMCSO bounced, and her child went without coverage for 60 days.
A common misconception is that Medi-Cal coverage means you write “none.” You do not. You list “Medi-Cal” with the child’s beneficiary identification number so the Department of Health Care Services can recover from any liable third party.
Signature and Filing
You sign and date the form under penalty of perjury per Code of Civil Procedure § 2015.5. You file the original with the clerk, who routes it to the California Child Support Central Registry. You do not serve the form on the other party.
The consequence of a missing signature is automatic rejection. The consequence of a perjured entry, such as a false employer, is up to four years in state prison under Penal Code § 126.
A common misconception is that filing by mail is fine. It is, but the date of filing is the date the clerk receives the form, not the date you mailed it under Code of Civil Procedure § 1013. Use certified mail or e-file through your county portal, such as LA Court e-file.
Three Common Scenarios with FL-235
The three most popular fact patterns each trigger different FL-235 entries and different downstream consequences. Use the tables below to map your facts to the right boxes.
Scenario 1: New Divorce With Two Children
Maria in Los Angeles County files for divorce and obtains a stipulated judgment ordering her ex to pay $1,200 per month in child support and to maintain Anthem Blue Cross coverage for the kids.
| Filing Step | Outcome for Maria |
|---|---|
| Section 2 marked “new order” with judgment date | Registry codes the case as active and triggers wage assignment |
| Section 5 lists the ex’s employer with FEIN | Earnings Assignment Order issues to employer within 10 days |
| Section 6 lists Anthem policy number and group | QMCSO routes correctly and kids stay covered with no gap |
Scenario 2: Modification After a Raise
Kevin in Santa Clara County files an FL-300 Request for Order to lower his support after a layoff, and the court reduces it from $900 to $450 per month.
| Filing Step | Outcome for Kevin |
|---|---|
| Section 2 marked “modified order” with new date | Old amount stops accruing; new amount goes live in CCSAS |
| Section 5 updated to “unemployed” with last day | LCSA pauses high wage assignment and avoids overcollection |
| Section 4 updated with new mailing address | Notices of any tax intercept reach Kevin in time to contest |
Scenario 3: Out-of-State Move by Custodial Parent
Sandra in Riverside County moves with the children to Arizona for a new job and must keep the California order alive while she registers it in Arizona under UIFSA.
| Filing Step | Outcome for Sandra |
|---|---|
| Section 4 updated with Arizona address within 10 days | California registry talks to Arizona registry through the federal hub |
| Section 5 updated with new Arizona employer | Wage assignment crosses state lines without a fresh court order |
| Section 6 updated with new health plan | Children’s coverage transitions without a QMCSO gap |
Mistakes to Avoid on FL-235
Every mistake on FL-235 has a measurable downstream consequence. The following list is drawn from the Judicial Council Self-Help Center intake notes and LCSA training materials.
- Skipping the SSN field for a child, which blocks federal tax intercept under the Treasury Offset Program and may delay arrears recovery by a full tax year.
- Listing a stale employer address, which voids any Earnings Assignment Order the employer receives and forces the obligee to refile.
- Leaving the case number blank, which causes the clerk to reject under Rule 2.100 and pushes the registry update past the 10-day window.
- Writing “self-employed” without an EIN or business name, which prevents the Financial Institution Data Match from finding bank accounts.
- Failing to update within 10 days of a job change, which violates Family Code § 4014 and exposes the party to contempt under Code of Civil Procedure § 1218.
- Misclassifying a “family support” order as plain child support, which strips the tax labeling that the parties bargained for in their marital settlement agreement.
- Listing Medi-Cal as “none,” which costs the Department of Health Care Services its third-party liability recovery rights and may trigger a state lien on the obligor.
- Signing without dating, which voids the perjury declaration under Code of Civil Procedure § 2015.5 and forces a refile.
- Filing FL-235 in the wrong county after a transfer under Code of Civil Procedure § 397.5, which orphans the data outside the active venue.
Do’s and Don’ts for FL-235
A short list of habits keeps your filing clean and enforceable.
Do’s:
- Do print a fresh blank from the Judicial Council site every time, because the form is updated periodically and an old version may be rejected.
- Do calendar a 10-day reminder after every job change or move, because Family Code § 4014 measures from the date of change.
- Do request the confidential filing envelope from the clerk, because it keeps your residence address out of the public file under Family Code § 17212.
- Do keep a stamped conformed copy in your records, because the LCSA sometimes asks for proof you filed.
- Do use the DCSS Customer Connect portal to mirror updates, because parallel updates close enforcement gaps fast.
- Do attach an FL-235 with every stipulated modification, because the order without the form is incomplete from the registry’s view.
Don’ts:
- Do not serve FL-235 on the other party, because doing so violates the privacy framework of Family Code § 17212.
- Do not estimate a child’s SSN, because perjury exposure under Penal Code § 126 is up to four years.
- Do not skip the form because you “told DCSS already,” because the court file and the DCSS file are separate systems.
- Do not file an unsigned form, because the clerk treats it as not filed under Code of Civil Procedure § 2015.5.
- Do not attach FL-235 to your public proof of service, because the form is confidential and must travel separately.
- Do not rely on a paralegal’s recall for the order date, because a wrong date voids the wage assignment.
Pros and Cons of California’s FL-235 System
The registry approach has measurable strengths and real weaknesses. Both sides matter when you decide how aggressively to police your data.
Pros:
- Centralized data lets the LCSA enforce orders quickly across all 58 counties through the California Child Support Automated System.
- Confidentiality rules under Family Code § 17212 protect domestic violence survivors from address disclosure.
- Federal interface through 42 U.S.C. § 654a lets California pursue obligors who move to other states.
- Health insurance fields tie directly into QMCSO enforcement, which keeps children covered without a second filing.
- The form is free, downloadable, and accepted in every county family law clerk’s office, which lowers the access-to-justice barrier for self-represented parties.
Cons:
- The 10-day update window is tight and easy to miss during a job transition or move.
- Self-represented parties often miss the form entirely because it is not on the standard divorce checklist in every county.
- Mistakes on the SSN or employer fields cause silent enforcement failures the filer may not learn about for months.
- Confidentiality protections do not extend to the obligor’s employer data, which can leak into the public order.
- The form’s plain layout hides nuance, and small errors trigger registry rejections that the clerk does not always flag in real time.
Key Entities Behind FL-235
Several agencies and statutes shape the FL-235 process. Knowing the players helps you push back when something goes wrong.
The Judicial Council of California drafts and publishes the form, including the periodic revision dates printed in the lower-left corner. The Department of Child Support Services runs the central registry and the LCSA network in each county. The federal Office of Child Support Services audits California for Title IV-D compliance and threatens funding clawbacks if the registry data lags.
The Department of Health Care Services uses Section 6 data to enforce Medi-Cal third-party liability. The Franchise Tax Board and the Treasury Offset Program use SSN data to intercept tax refunds. The Employment Development Department cross-checks the employer fields through new-hire reporting under Unemployment Insurance Code § 1088.5.
Recap of Relevant Rulings
Although FL-235 itself rarely produces published opinions, the underlying support framework has anchored several leading California decisions. In re Marriage of Cheriton (2001) 92 Cal.App.4th 269 confirms that accurate income disclosure is non-negotiable in setting support, which is why Sections 4 and 5 of FL-235 must be precise. County of Stanislaus v. Gibbs (1997) 59 Cal.App.4th 1417 underscores LCSA standing to enforce, which depends on registry data.
In re Marriage of Lim and Carrasco (2013) 214 Cal.App.4th 768 illustrates how missing employer information undermines arrears proof. In re Marriage of Boswell (2014) 225 Cal.App.4th 1172 confirms that registry-based wage assignments survive interstate moves when UIFSA paperwork follows the FL-235 update. Each case ties accurate FL-235 data directly to enforceability.
FAQs
Do I have to file FL-235 if my divorce has no support order?
No. FL-235 is required only when the court issues a child support, family support, or spousal support order, so a no-support judgment does not trigger the form under Family Code § 4014.
Is my home address on FL-235 visible to the other parent?
No. The form is confidential under Family Code § 17212 and is not served on the other party, so your residence address stays out of the public file and the served packet.
Can I file FL-235 electronically in California?
Yes. Most counties accept e-filing through approved vendors like One Legal or county portals such as LA Court e-file, and the clerk routes the confidential form to the registry on receipt.
Do both parents file separate FL-235 forms?
Yes. Each party files an individual FL-235 with their own data, because the registry must capture each party’s address, employer, and contact information for two-way enforcement under 42 U.S.C. § 654a.
Will I be penalized for filing FL-235 late?
Yes. Late filing past the 10-day window in Family Code § 4014 can trigger contempt under CCP § 1218, with fines up to $1,000 per count and possible jail time.
Does FL-235 replace the Income and Expense Declaration FL-150?
No. FL-150 reports income for setting or modifying support, while FL-235 feeds the case registry, so the two forms serve different purposes and are filed at different stages.
Can I redact my SSN on FL-235?
No. Federal law at 42 U.S.C. § 666(a)(13) requires the SSN, and California shields it through registry confidentiality rather than redaction on the form.
Do I need a lawyer to file FL-235?
No. Self-represented parties file FL-235 every day with help from the court self-help center, because the form is short, free, and supported by clerk-level guidance in every county.
Is the FL-235 the same as the older FL-191?
No. California retired FL-191 and replaced it with FL-235, which captures additional employer and health insurance fields, although counties may still reference the prior form name in legacy paperwork.
Will filing FL-235 start a wage assignment automatically?
No. FL-235 supplies registry data, but the wage assignment requires a separate Earnings Assignment Order FL-195 issued by the court, which the LCSA serves on the employer.
What if I do not know the other parent’s SSN?
Yes, you may file with the data you have. You complete only your own party fields, write “unknown” where required for the other party, and let the LCSA use the Federal Parent Locator Service to fill the gap.
Can I update FL-235 without going back to court?
Yes. Updates to address, employer, or health insurance are filed directly with the clerk on a fresh FL-235, with no hearing required, because the update is administrative under Family Code § 4014.
