California's adult-adoption guidance requires the adopting adult to be older than the adult who will be adopted. Being 18 or older is therefore not the only age question. The official court guide does not set an upper age cutoff for an adult adoptee, but the age relationship and the rest of the adoption requirements still need to be satisfied.
Check the two ages together
| Check | What to record |
|---|---|
| Adult status | The parties' dates of birth and the appropriate adult-adoption procedure. |
| Older adopter | Which person is older and will become the adopting parent. |
| Consistent identities | Matching names and birth information throughout the packet. |
| Other requirements | Agreement, applicable consents, prior-adoption issues and the court's approval. |
California Courts' adult-adoption guide expressly identifies the older-adopter requirement. The currently linked Sonoma petition, dated 2013, also has a field confirming that the petitioner is an adult older than the proposed adoptee. Confirm the currently accepted form in your own filing county.
Age does not reverse the parent-child roles
The person asking to become the legal parent is the adopter. The person becoming the legal child is the adoptee. If an adult stepchild wants to formalize the relationship, the desired result usually has the stepparent adopting the adult stepchild. Do not switch the roles on the forms to get around the age requirement.
This answer addresses people who are already adults. If either person is under 18, obtain guidance on the applicable procedure instead of using this adult checklist as an eligibility decision.
Review the requirements beyond age
A willing adult still needs an agreement and the appropriate petition. If either party has a spouse or domestic partner, review the applicable consent requirements. Section 9303 also makes some recent unrelated-adult adoptions relevant. An age comparison alone cannot clear those issues.
Under section 9328, the judge considers the parties' best interests and the public interest. Do not treat an older adopter as a guaranteed approval.
Plan thoughtfully for a later-life adoption
If the adoptee or stepparent is older, discuss the purpose of the adoption, practical hearing arrangements and any separate estate or health-care planning. Continue with the later-life guide for that preparation. Confirm hearing arrangements and applicable consents with the filing court before relying on a completion plan.
