How Much Does Stepparent Adoption Cost in California 2026

The short answer: the court side of a California stepparent adoption is much cheaper than most families expect. California's official self-help guide lists a $20 filing fee and a court investigator's fee of up to $700, and both can be waived for families who qualify. Add document preparation ($349 with StepParent Adoption 360), Live Scan fingerprinting, and, only if needed, a newspaper publication and an added investigation when you ask the court to end the other parent's rights. In our experience, about 80% of the stepparent adoptions we've completed went forward without the other biological parent's consent, so it's worth knowing that cost path too.

1. The Court Filing Fee

The California Courts self-help page on filing a stepparent adoption request says, "You'll need to pay a fee of $20 to the clerk when you file your forms." Some counties apply it per child. Solano County's packet, for example, charges $20 for each person being adopted, so three children cost $60. Amador County's instructions also list a $20 filing fee.

You file in the superior court for your county, using the statewide Judicial Council forms, starting with the ADOPT-200 Adoption Request.

2. The Court Investigator's Fee

Every California stepparent adoption includes an investigation. The court's self-help guide explains that it "does not require a full 'home study'" but that the investigator may visit the home where the child lives, then files a report the judge reviews before the hearing.

According to the same guide, you may be asked to pay a stepparent adoption investigator's fee of up to $700 at the time of filing. Counties set their own amounts. Two examples from county court documents:

• Solano County: the adoption investigation fee is usually $500, and the investigation won't start until it's paid in full.
• Amador County: a $200 court investigation fee.

Fees change over time, so check your own county's current amount.

Hiring your own investigator

The self-help guide says you can choose to hire your own qualified professional instead (a licensed clinical social worker, marriage and family therapist, professional clinical counselor, or a licensed private adoption agency). But if you hire your own, you can't waive that investigator's fee. For most families, the court investigator is the simpler and cheaper route.

3. Fee Waivers Can Bring Court Costs to Zero

California's fee waiver covers both the filing fee and the court-ordered investigator's fee. The self-help guide lists three ways to qualify: you receive public benefits, your income is below a set amount, or you can't pay the fee and still meet your basic needs. You file two forms:

4. Live Scan Fingerprinting

The court investigator runs a criminal background check on the adopting stepparent using a Request for Live Scan Service form. Solano County's packet, for example, says you'll receive a list of agencies that do Live Scans and must return proof of the scan to the investigator's office. The provider sets the fee.

5. If the Other Parent Hasn't Consented

This is the most common situation we see. When the other parent has been out of the picture, California lets you ask the court to declare your child free from his custody and control under Family Code § 7822. The petition form used by California courts frames it simply: the parent hasn't communicated with the child for more than one year, or hasn't provided for the child's support for more than one year. Once the court grants it, the adoption goes forward without his signature. The father never signs, and the judge approves the adoption anyway.

That petition comes with its own investigation, which is where most of the extra cost is:

• Amador County: an additional $750 court investigation fee when you ask to end the other parent's rights.
• Solano County: an additional investigation that can cost $200 to $400.

If your family qualifies for a fee waiver, ask the clerk how it applies to this added fee too.

6. Publication, If the Other Parent Can't Be Found

When you don't know where the other parent is, California courts use a routine process: you document a diligent search, ask the court for an order to publish the citation in a newspaper, and publish it as ordered. Amador County's packet, for example, lists an Ex Parte Application for Publication of Citation and an Order on that application. The newspaper sets the price. If he doesn't respond, the case goes forward.

7. Costs That Are Usually Small

• Certified copies of your child's birth certificate, your marriage certificate (or Certificate of Domestic Partnership), and any prior divorce or custody judgments. The court investigator needs certified copies, not photocopies.
• Certified copies of the adoption order after the hearing, for school, insurance and Social Security.
• The new birth certificate. For a child born in California, the clerk sends the Court Report of Adoption (VS-44) to the state Office of Vital Records, which prepares the new certificate.

What You Generally Won't Pay For

• A full home study. California stepparent adoptions use the shorter court investigation instead.
• A lawyer, in an uncontested case. Many families file with the statewide forms and the court's self-help guide. If the other parent actively contests the adoption, that's the time to talk with a California family law attorney.

Who Qualifies for This Process?

California's stepparent adoption is for the spouse or registered domestic partner of the child's parent. If you're not married or registered, you can't use the stepparent process; ask a California family law attorney about other routes. See the California state guide for the full process.

Frequently Asked Questions

What's the total court cost for a California stepparent adoption?

For a consenting or deceased other parent, the main court costs are the $20 filing fee and the court investigator's fee of up to $700 (set by county). Ending an absent parent's rights adds a separate investigation fee, and publication adds the newspaper's charge. Fee waivers can cover the filing and investigator fees.

Can I get the fees waived?

Yes, if you receive public benefits, have income below a set amount, or can't pay and still meet basic needs. File FW-001 and FW-002, listing "Court Ordered Investigator's Fee" on FW-002, according to California's self-help guide.

Can I adopt my stepchild in California without the father's consent?

Yes. If he hasn't communicated with or supported the child for more than a year, you can ask the court to free the child from his custody and control under Family Code § 7822, then finish the adoption. In our experience, about 80% of the stepparent adoptions we've completed went forward without the other parent's consent; the father never signed, and the judge approved the adoption anyway.

Do I have to pay for a home study?

No full home study is required. California uses a court investigation, which may include a home visit, with a fee of up to $700 that can be waived if you qualify.

What does StepParent Adoption 360 charge?

$349 for the first child and $99 for each additional child for the complete document package. Court fees, Live Scan, publication and certified copies are paid separately.
