Adult Adoption California

Most people who search for "adult adoption California" are either an adult who wants to be legally adopted by a stepparent or family friend who raised them, or a parent-figure who wants to formalize a bond that has existed for years without a legal document to show for it. What surprises nearly everyone is how straightforward the California legal process actually is — and how small the cost can be compared to infant adoption.

The catch is knowing exactly which forms to file and what the court is looking for.

Who Can Adopt an Adult in California

California Family Code § 9300 allows any adult to adopt another adult, with one fundamental requirement: both parties must consent. Unlike adoption of a minor, there is no investigation by CDSS, no home study, and no background check required. The court's role is to confirm that the adoption is voluntary and that it is not being used to commit fraud — for example, to create false inheritance rights or to circumvent immigration law.

There is no minimum or maximum age gap required. A 40-year-old can adopt a 38-year-old. A 65-year-old can adopt a 52-year-old. California courts have approved adult adoptions in a wide range of circumstances: stepparents formalizing a lifelong relationship, grandparents who raised their grandchildren, foster parents maintaining a bond with former foster youth who aged out of the system, and family friends who became de facto parents during critical years.

The one meaningful restriction: if the person being adopted is married, their spouse must consent to the adoption unless the court finds the spouse's consent cannot be obtained or that the requirement should be waived.

The Legal Process: Simpler Than You Think

The California adult adoption process takes place entirely in the Superior Court of the county where the adopting parent resides. The required forms are a subset of the standard adoption packet:

• ADOPT-200: Adoption Request
• ADOPT-210: Adoption Agreement (signed by both parties)
• ADOPT-215: Adoption Order (signed by the judge at the final hearing)
• VS 44: Court Report of Adoption (filed after the hearing to trigger issuance of a new birth certificate)

Both parties appear at the finalization hearing together. Unlike minor adoptions, there is no waiting period, no supervision period, and no investigation report that must precede the hearing. Courts typically schedule adult adoption hearings within 30 to 60 days of filing, depending on the county's calendar.

Court filing fees for adult adoptions run $435 to $500 in most California counties — a statewide flat filing fee applies to adoption proceedings. Some counties charge a small additional administrative fee.

What Changes After the Adoption Is Final

Once the adoption order is entered:

Name change: The adopted adult may take the adopting parent's surname. The new birth certificate issued by California Vital Records will list the adoptive parent as the legal parent, with the adoptee's updated name if a name change was requested.

Inheritance rights: The adopted adult has the same inheritance rights as a biological child — including the right to inherit under California intestate succession law if there is no will. This is often the primary legal motivation. Family members who want to ensure that the person who actually raised them is protected under inheritance law use adult adoption as the formal mechanism.

Social Security and benefits: Adult adoptees can potentially access Social Security survivor benefits based on the adoptive parent's record, though the specifics depend on federal eligibility rules at the time of the claim.

Termination of prior legal parentage: The adoption terminates the legal relationship between the adoptee and their biological parents (or previously adoptive parents) unless the court orders otherwise. This is a permanent change. Families should think carefully about the implications for existing inheritance arrangements and relationships before proceeding.

Costs: Realistic Numbers

Attorney fees for an uncontested adult adoption in California typically run $1,000 to $3,500 for representation through finalization. Some attorneys offer flat-fee packages specifically for adult adoption because the process is predictable and unlikely to require extended litigation.

Several attorneys in Southern California and the Bay Area who specialize in adult adoption publish their flat fee schedules online. Comparing a few before retaining anyone is straightforward.

For families comfortable with the paperwork, the California Courts Self Help Guide provides all the required forms and filing instructions. Unrepresented parties (self-represented litigants) regularly complete adult adoptions in California without an attorney. The forms themselves are clear, the process is linear, and the hearing is usually brief.

Total out-of-pocket cost for a self-represented adult adoption: $435 to $500 in filing fees plus document costs. With an attorney: $1,500 to $4,000 in most cases.

The New Birth Certificate and Record Access

After the adoption is finalized, the certified Adoption Order and VS 44 are sent to California Vital Records. Under SB 1186 (effective 2026), Vital Records must issue the new birth certificate within 11 weeks of receiving the adoption report — a major improvement from prior processing times that sometimes exceeded a year.

For adoptees accessing records about their original biological parentage, SB 381 (2026) now allows adult adoptees 18 and older to petition the Superior Court for their original, unredacted birth certificate. The court provides notice to birth parents, who have 30 days to opt for redaction or disclosure of contact preferences. This is separate from the adult adoption process but relevant for anyone who was adopted as a child and is now seeking information about their origins.

Common Scenarios and What to Expect

Stepparent adopting an adult stepchild: The most frequent scenario. The biological parent whose rights would be terminated must consent (or those rights must already be legally absent through a prior court proceeding). Both parties file jointly, appear together, and the hearing is typically a formality.

Foster parent adopting former foster youth: Many foster parents and former foster youth choose to formalize their bond after the youth ages out of the system. California extended foster care under AB 12 allows youth to remain in care until 21, giving some families an extended transition period before pursuing formal adoption.

Family friend who served as a de facto parent: Courts evaluate these cases on consent — both parties agree, both sign the Adoption Agreement, both appear at the hearing. The court does not investigate the nature of the prior relationship unless there is a specific reason for concern.

If the scenario involves any complication — a biological parent who cannot be located, a prior adoption that needs to be factored in, or a name change across multiple documents — working with an attorney is worth the cost for the peace of mind.
