If you are an unmarried parent in California and you need a court to officially recognize who the legal parents of a child are, you file Form FL-200, also called the Petition to Establish Parental Relationship. This single form opens a parentage case under the Uniform Parentage Act so a judge can issue legal orders for custody, visitation, child support, and even who is named on the birth certificate.
Roughly 40% of California births each year are to unmarried parents, according to the California Department of Public Health vital statistics, which means hundreds of thousands of families need a parentage order to lock in their rights. Without an FL-200 (or a signed Voluntary Declaration of Parentage), a parent has no enforceable legal relationship with the child, no matter what the birth certificate says.

What Form FL-200 Actually Does
Form FL-200 is the official Judicial Council form used to start a parentage action when the parents were not married when the child was born. It tells the superior court who the parents are, who the child is, and what orders the petitioner wants. The form is the first paper in the case file and triggers all later orders for custody, visitation, and support.
The form lives inside California Family Code section 7630, which gives a child, a parent, or an alleged parent the right to bring an action to declare a parent-child relationship. The consequence of skipping FL-200 is severe: a non-marital parent who never files cannot legally enforce visitation, claim custody in an emergency, or stop the other parent from moving away with the child. A common misconception is that being on the birth certificate is enough; in California, the certificate is evidence of parentage but not a court order, so it can be overcome by a genetic test under Family Code §7551.
A real-world example: Maria gives birth in San Diego, and Diego signs the birth certificate at the hospital but never signs a POP declaration. Two years later, Diego wants weekend visits, but Maria refuses. Without FL-200, Diego cannot ask the court to enforce a visitation schedule. After he files FL-200, the court sets a hearing and can issue temporary orders within weeks.
Who Can File FL-200
The list of people allowed to file is broader than many parents think. Under Family Code §7630, a child, the child’s natural mother, a man presumed to be the father, an alleged genetic father, an intended parent under a surrogacy agreement, or a Local Child Support Agency may file. Each of these people has standing, which is the legal right to ask the court for a ruling.
The consequence of filing without standing is dismissal, which wastes the filing fee and resets the clock. For example, a grandparent cannot file FL-200 to establish that her son is the father; only the son, the mother, the child, or the LCSA can do that. A common misconception is that a stepparent can use FL-200 to establish parentage; stepparents must instead use a stepparent adoption or a Family Code §7611(d) presumed-parent claim.
A real-world example: Jamal is the alleged genetic father of a child born to Tasha, who is married to another man. Jamal can file FL-200 within two years of the child’s birth under Family Code §7541; after that window, the marital presumption usually wins, and his case can be dismissed.
When You Should Not Use FL-200
If the parents were married when the child was born or conceived, the correct first paper is FL-100 (Petition for Dissolution) or FL-270 (Petition for Custody and Support of Minor Children), not FL-200. Filing the wrong form delays your case by 30–90 days because the clerk may reject the petition or the judge may order you to refile.
If you and the other parent already signed a Voluntary Declaration of Parentage and neither of you rescinded it within 60 days, that POP has the force of a judgment under Family Code §7573, and you do not need FL-200 to establish parentage. You may still file FL-260 (Petition for Custody and Support) to get custody and support orders.
A real-world example: Priya and Sam signed a POP at the hospital in 2024 and never rescinded it. In 2026, Sam wants formal custody orders. He files FL-260, attaches the POP, and skips FL-200 entirely, saving filing time and avoiding a duplicate parentage finding.
The Uniform Parentage Act in Plain English
The Uniform Parentage Act, codified at California Family Code §§7600–7730, is the master statute that controls every FL-200 case. It tells judges who counts as a parent, how to prove parentage, and what presumptions apply. The Act is gender-neutral, so the words mother and father are interchangeable with parent in most sections.
The plain-English rule is that California recognizes parentage based on biology, marriage, holding-out, intent, and adoption. The consequence of being declared a parent is full parental rights and full duties: custody, visitation, decision-making, and a support obligation that lasts until the child turns 18 (or 19 if still in high school) under Family Code §3901. A common misconception is that biology always wins; in California, a §7611(d) presumed parent who has openly held the child out as his or her own can defeat a genetic father, as the Supreme Court confirmed in In re Nicholas H. (2002) 28 Cal.4th 56.
The Five Routes to Parentage
There are five main routes a court uses to declare parentage on an FL-200 case. Each route has its own evidence and its own pitfalls.
The first route is birth to a marriage, which is mostly handled outside FL-200. The second is genetics, proven by a §7551 genetic test. The third is holding out under §7611(d), where a person receives the child into his or her home and openly treats the child as their own. The fourth is intent under §7613, used in assisted-reproduction and surrogacy cases. The fifth is adoption, which is a separate proceeding but can be confirmed in a parentage judgment.
A real-world example: Rosa and Lin, an unmarried lesbian couple, used a sperm donor and raised twins together for four years. Lin can claim presumed parentage under §7611(d) by showing she lived with the children and held them out as her own, even without genetics, as in Elisa B. v. Superior Court (2005) 37 Cal.4th 108.
Key Court Rulings You Should Know
Elisa B. v. Superior Court extended §7611(d) to same-sex parents and made clear a child can have two mothers. In re Nicholas H. held that a man without genetic ties can still be the legal father if he held the child out. Jason P. v. Danielle S. (2017) 9 Cal.App.5th 1141 confirmed a known sperm donor can become a §7611(d) presumed parent if he later parents the child.
These rulings shape FL-200 strategy because they tell the court that the facts of the relationship often matter more than the genetics. The consequence for petitioners is that strong declarations describing day-to-day parenting can win a parentage case even against a biological challenger. A common misconception is that DNA settles the case; in California, DNA is one factor among many.
Step-by-Step: Filling Out FL-200
The current FL-200 (rev. January 1, 2023) is two pages with eleven numbered items. The clerk will reject the form if any required box is blank, the caption is wrong, or the petitioner does not sign. Use blue or black ink, or fill it out using the fillable PDF on the Judicial Council site.
The 2026 Statewide Civil Fee Schedule sets the first-paper filing fee at $435–$450 depending on the county. If you cannot afford the fee, file FW-001 (Request to Waive Court Fees) along with FL-200.
The Caption (Top of Page 1)
The caption is the box at the very top. Enter your full name, address, phone number, and email if you have one. If you are afraid for your safety, use a confidential mailing address under CCP §367.3 and check the Safe at Home program through the California Secretary of State.
Write the name and street address of the superior court for the county where you or the other parent lives. Filing in the wrong county leads to a change of venue motion under Code of Civil Procedure §397, which can delay your case by 60 days. A common misconception is that you must file where the child was born; venue actually follows the parents’ residence.
In the Petitioner and Respondent boxes, write the full legal names of the parents, not nicknames. Leave the case number blank because the clerk will assign one when you file.
Item 1: Petitioner’s Information
Item 1 asks for the petitioner’s relationship to the child. Check the box for mother, father, parent, child, personal representative of the child, or adoption agency. The box you check controls standing and tells the court which §7630 category you fit.
The consequence of checking the wrong box is a demurrer or motion to quash, which can knock the case out before any orders issue. For example, Carlos checks father but is actually only an alleged genetic father with no §7611 presumption; the court will still hear his case under §7630(b), but he must prove genetics through a §7551 test.
A common misconception is that parent and mother mean the same thing on the form. They do not; parent is the gender-neutral box used by same-sex parents and intended parents under §7613.
Item 2: Respondent’s Information
Item 2 mirrors Item 1 for the other parent. If you do not know the respondent’s address, you may serve by publication after a diligent search, as authorized by Code of Civil Procedure §415.50. Publication adds 60–90 days and roughly $200–$600 in newspaper costs.
A real-world example: Aisha does not know where her child’s father, Marcus, lives. She files FL-200, checks the box for service by publication, and submits an Application for Publication. The court grants publication, the notice runs four weeks in a local paper, and Aisha proceeds to default if Marcus does not respond.
A common misconception is that you can list unknown and stop. You must show the court a declaration of due diligence describing the searches you ran (Department of Motor Vehicles, social media, last known employer, military locator service).
Item 3: Children of the Parties
Item 3 lists every child you want included in the parentage case. Write each child’s full legal name, date of birth, sex, and age. If the mother is currently pregnant, check the unborn child due box and list the estimated due date.
The consequence of leaving a child off Item 3 is that the judgment will not cover that child, and you will need to file a separate FL-200 or an amended petition. For example, Tania has two children with Andre but only lists the older one. The judgment binds only the older child, and Tania must reopen the case to add the younger one, paying another motion fee under the Statewide Fee Schedule.
A common misconception is that children born after the petition are auto-included. They are not; California requires a fresh filing or amendment for each later-born child.
Item 4: Statement of Facts
Item 4 is where you state under penalty of perjury that the petitioner is or is not a parent of each child. Check the boxes that match your case, and attach Form FL-210 attachment pages if you need more room.
The consequence of a false statement is a perjury charge under Penal Code §118, which is a felony punishable by up to four years in state prison. A real-world example: Ben swears he is not the father to dodge support, but a §7551 test later proves he is; the court can refer his perjury to the district attorney.
A common misconception is that you can leave Item 4 vague to protect yourself. Vague answers are treated as denials, which forces a contested hearing and slows your case.
Item 5: Uniform Child Custody Jurisdiction and Enforcement Act
Item 5 directs you to attach a completed Form FL-105 (UCCJEA Declaration), which lists every place the child has lived for the past five years. The UCCJEA controls which state has jurisdiction to make custody orders.
The consequence of an incomplete FL-105 is dismissal of the custody portion of the case and possible referral to another state, which can erase months of work. For example, Lucia files in Los Angeles, but the children lived in Texas for the last six months; under the UCCJEA home state rule, Texas has jurisdiction, and the California case must be transferred or dismissed.
A common misconception is that California always has jurisdiction because a parent lives here. Jurisdiction follows the child’s home state, not the parents.
Item 6: Other Court Cases
Item 6 asks whether any other case (criminal protective order, dependency, prior parentage) involves the child or the parties. List case numbers and courts. Failing to disclose a related case can lead to inconsistent orders and possible sanctions under Family Code §271.
Items 7–9: Requests for Orders
Items 7, 8, and 9 are the prayer of the petition. Check each box for the orders you want: a parentage finding, legal and physical custody, visitation, child support, health insurance, attorney’s fees, and a name change for the child.
The consequence of not checking a box is that the court cannot grant that relief later without an amended petition or a Request for Order (FL-300). A real-world example: Sofia forgets to check child support; she gets a custody order but no support, and she must file FL-300 and wait another 60 days for a hearing.
A common misconception is that joint custody is automatic. Custody must be requested and proven; California’s Family Code §3040 directs the court to make orders in the best interest of the child, not by default.
Item 10: Attorney Fees
Item 10 lets you ask the other parent to pay your attorney’s fees and costs under Family Code §7605. To win fees, file FL-319 and an Income and Expense Declaration (FL-150) showing a financial disparity.
Item 11: Signature
Item 11 is your signature under penalty of perjury. Sign and date the form using your full legal name. An unsigned petition is rejected by the clerk and never becomes a filed case.
Companion Forms You Will Likely File
Filing FL-200 alone rarely gets you everything you want. Most petitioners file a packet of related Judicial Council forms at the same time to lock in jurisdiction, request orders, and start service.
The standard packet costs the same first-paper fee because the additional forms are filed with FL-200, not separately. Filing them later costs extra motion fees of about $60 each under the civil fee schedule.
Summons (FL-210) and Proof of Service
Form FL-210 (Summons) tells the respondent he or she has 30 days to file FL-220 (Response). The summons must be personally served along with FL-200, FL-105, and any blank response forms.
The consequence of bad service is no jurisdiction over the respondent and no enforceable judgment. A real-world example: Kevin mails FL-200 by regular post; the court holds service void, and he must redo it through a registered process server.
A common misconception is that texting a photo of the documents counts. Personal service requires hand delivery by an adult who is not a party, with a Proof of Service of Summons (FL-115) filed afterwards.
UCCJEA Declaration (FL-105)
FL-105 is mandatory in every case involving a minor child. It lists addresses for the past five years and identifies anyone with physical custody.
Request for Order (FL-300)
If you need temporary orders before the case ends, file FL-300 with FL-200. FL-300 sets a hearing within 20–60 days where the judge can issue temporary custody, visitation, support, and even genetic-testing orders.
Income and Expense Declaration (FL-150)
FL-150 is required to set child support. The court uses statewide DissoMaster guideline calculations to compute support based on each parent’s gross income, time-share, and tax filing status.
Judgment (FL-250) and Notice of Entry (FL-190)
When the case ends, the court signs FL-250 (Judgment) and the clerk mails FL-190 (Notice of Entry of Judgment). The judgment is the document you take to the California Department of Public Health to amend a birth certificate.
Three Real-World Scenarios
Below are the three most common fact patterns we see in California parentage cases. Each one shows how the petitioner’s choices on FL-200 line up with the result the court enters.
Scenario 1: Unmarried Mother Seeking Support
| What Maria Does | What the Court Orders |
|---|---|
| Files FL-200, checks mother, lists newborn, requests support and custody | Issues guideline support, joint legal custody, primary physical custody to Maria |
| Attaches FL-105 showing California home state | Confirms California jurisdiction under UCCJEA |
| Serves Diego personally with FL-210 and FL-200 | Gets a default judgment when Diego does not respond in 30 days |
Scenario 2: Father Seeking Visitation
| What Jamal Does | What the Court Orders |
|---|---|
| Files FL-200 as alleged father, requests genetic testing | Orders §7551 test; results confirm paternity |
| Files FL-300 for temporary visitation | Sets supervised visits pending final judgment |
| Files FL-311 with proposed parenting plan | Adopts plan with weekly visits and alternating holidays |
Scenario 3: Same-Sex Co-Parent Under §7611(d)
| What Lin Does | What the Court Orders |
|---|---|
| Files FL-200 as parent, cites §7611(d) and Elisa B. | Declares Lin a presumed parent of the twins |
| Submits declarations from family showing she held twins out as her own | Finds the §7611(d) presumption applies |
| Requests joint custody and child support | Issues joint legal and physical custody, guideline support |
Three Named Examples to Anchor the Rules
Concrete people make the rules easier to remember. Each example below maps a single Family Code section to a person and a goal.
Example A — Genetic testing under §7551. Elena is unsure whether her ex, Marcus, is the father of her toddler. She files FL-200 and checks the box for genetic testing. The court orders a buccal swab through LabCorp at Marcus’s expense if he is found to be the father.
Example B — Holding-out under §7611(d). Andre lived with his girlfriend’s son for six years, paid for school, and called the boy my son at family events. After the breakup, Andre files FL-200, attaches photo evidence and witness declarations, and is declared a presumed parent under In re Nicholas H..
Example C — Intent under §7613 assisted reproduction. Priya and Anika used a known sperm donor with a written agreement disclaiming his rights under Family Code §7613(b). Anika files FL-200 as parent, attaches the agreement, and the court enters judgment naming both women as parents and barring the donor from claims.
Mistakes to Avoid
Filing FL-200 looks simple until a small error causes a big delay. The clerks at the Los Angeles Superior Court and San Diego Superior Court report that roughly one in three self-filed packets is rejected the first time.
- Wrong county. Filing in a county where neither parent lives triggers a venue motion under CCP §397 and a 60-day delay.
- Missing FL-105. Skipping the UCCJEA Declaration leads to dismissal of the custody requests.
- Unsigned petition. The clerk rejects unsigned forms on sight, costing one to two weeks for a refile.
- Wrong respondent box. Checking father when the law calls the person parent can confuse the court and the registrar.
- Failure to request specific orders. If you do not check a box for support, custody, or visitation, the court cannot grant it later without an amendment.
- Improper service. Mailing or texting the petition is invalid; only personal service by a non-party adult satisfies CCP §415.10.
- Not filing FL-150. Without an Income and Expense Declaration, the court cannot run guideline support.
- Listing only one child. Each child must appear in Item 3, or the judgment will not bind the omitted child.
- Skipping the fee waiver. Eligible filers who pay $450 anyway leave money on the table; FW-001 is free to submit.
- Ignoring the marital presumption. Filing against a married mother without addressing Family Code §7540 often leads to dismissal.
Do’s and Don’ts
The points below come straight from the California Courts Self-Help Center on parentage and from common judicial officer feedback.
- Do file FL-200 in the county where you or the other parent lives, because venue follows residence under CCP §395.
- Do attach FL-105 every single time, because the UCCJEA is mandatory in any custody-related case.
- Do request genetic testing in Item 9 if biology is in dispute, because §7551 gives you the right.
- Do keep three copies: one for the court, one for the respondent, and one for your records, because clerks do not make free copies.
-
Do ask for fees and costs under §7605 when there is income disparity.
-
Don’t file by email; FL-200 must be filed in person, by mail, or through the county’s eFile portal, because clerks reject improperly filed forms.
- Don’t serve the respondent yourself, because CCP §414.10 bars parties from serving their own papers.
- Don’t lie on Item 4, because perjury is a felony under Penal Code §118.
- Don’t ignore the 30-day response window if you are the respondent, because default can wipe out your rights.
- Don’t assume the birth certificate is a court order, because it is not; only a judgment under FL-250 is enforceable.
Pros and Cons of Filing FL-200
Every legal action has trade-offs. The chart below helps you weigh whether to start a parentage case yourself or wait for the Local Child Support Agency to do it.
- Pro: You control the timeline, because you pick the filing date and hearing dates.
- Pro: You can request custody and visitation, which the LCSA cannot do; the LCSA only handles support.
- Pro: You can ask for attorney’s fees under §7605, which can shift costs to the higher earner.
- Pro: You lock in legal parentage, which protects Social Security survivor benefits and inheritance rights.
-
Pro: A judgment can correct the birth certificate through the California Office of Vital Records.
-
Con: Filing fees of $435–$450 hit fast unless you qualify for a fee waiver.
- Con: The other parent gains rights too, including joint custody and decision-making power.
- Con: Genetic tests can produce surprising results that change the case.
- Con: Court hearings are public, so sensitive facts may appear on the record.
- Con: Self-represented filers face a steep learning curve, and small errors cost weeks.
Federal Law Backdrop
Federal law sets the floor for state parentage rules. Title IV-D of the Social Security Act requires every state to run a child support enforcement program, which is why California has an LCSA in every county. 42 U.S.C. §666 requires states to offer voluntary acknowledgment of paternity programs, which is why California has the POP declaration.
The consequence of these federal rules is that any California parentage judgment is entitled to full faith and credit in every other state under 28 U.S.C. §1738B. For example, a California FL-250 judgment is enforceable in Nevada or Arizona without relitigation. A common misconception is that moving across state lines erases the judgment; it does not.
County-Specific Procedures
Each county adds local rules on top of the statewide forms. The Los Angeles Superior Court Local Rules require electronic filing for most family cases. The San Diego Family Court requires a Family Court Services mediation orientation before any custody hearing. The Alameda County Superior Court uses a Family Law Facilitator office that reviews FL-200 packets free of charge for self-represented parties.
The consequence of ignoring local rules is rejection of the filing or a continuance of the first hearing. For example, Daniel files FL-200 in Los Angeles by paper when eFiling is mandatory; the clerk rejects the filing, and Daniel loses two weeks. A common misconception is that statewide rules override local rules; in reality, local rules add procedural steps that you must follow.
Key Entities You Will Encounter
- Judicial Council of California drafts the FL-200 form and sets statewide rules.
- California Department of Child Support Services runs the LCSA network and can file or join your case.
- California Department of Public Health, Office of Vital Records issues and amends birth certificates.
- California Family Law Section of the State Bar certifies family-law specialists who often handle complex FL-200 cases.
- Family Court Services in each county provides mandatory custody mediation.
- Local Family Law Facilitator offers free help to pro per parents.
Each entity plays a different role: the Judicial Council makes the form, the courts file it, the LCSA enforces support, and Vital Records records the result.
Recap of Court Rulings
The California Supreme Court and Court of Appeal have shaped FL-200 practice through key cases. Elisa B. v. Superior Court opened §7611(d) to same-sex parents. In re Nicholas H. confirmed that genetics is not required for presumed parentage. Jason P. v. Danielle S. addressed known sperm donors. Susan H. v. Jack S. (1994) 30 Cal.App.4th 1435 addressed time limits for challenging the marital presumption.
These decisions shape the language you should use in Item 4 of FL-200. Citing the holding-out facts in your declaration helps the court apply Elisa B. and Nicholas H. to your case. The consequence of failing to cite them is that the judge may default to genetics, which can hurt non-biological parents.
FAQs
Do I need a lawyer to file FL-200?
No. California allows self-representation in family law, and free help is available through the Family Law Facilitator in every county; complex contested cases still benefit from counsel.
Can I file FL-200 if the other parent lives in another state?
Yes. California courts can hear the case if California is the child’s home state under the UCCJEA; long-arm jurisdiction over the out-of-state parent comes from Family Code §7620.
Is genetic testing automatic on FL-200?
No. You must request testing in Item 9 or by motion; the court orders a §7551 test only when paternity is in dispute.
Can same-sex parents use FL-200?
Yes. Both parents can be declared legal parents under Family Code §7611(d) and Elisa B.; check the gender-neutral parent box on the form.
Does signing a Voluntary Declaration of Parentage replace FL-200?
Yes. A signed POP has the force of a judgment under Family Code §7573; you only need FL-200 to add custody, visitation, or support orders.
Can I get child support through FL-200?
Yes. Check the support box in Item 9 and file FL-150; the court calculates guideline support under Family Code §4055.
Will FL-200 change the child’s birth certificate?
Yes. After judgment, take certified copies of FL-250 to the Office of Vital Records; the registrar issues an amended certificate.
Is there a deadline to file FL-200?
No. Parentage actions usually have no statute of limitations under Family Code §7630(b); however, a challenge to the marital presumption must be filed within two years.
Can I file FL-200 anonymously?
No. California requires the petitioner’s name on the form; victims of abuse can shield their address through Safe at Home and confidential filings.
Do I have to attend court in person?
No. Many California courts allow remote appearances under Code of Civil Procedure §367.75; check your county’s remote appearance policy before the hearing.
Can the Local Child Support Agency file for me?
Yes. The LCSA can open a Title IV-D case and file FL-600 on your behalf, but the agency only addresses support, not custody.
What happens if the respondent does not answer?
Yes, you can take a default. After 30 days, file FL-165 (Request to Enter Default) and submit a proposed FL-250 judgment for the judge to sign.
