How much does adult adoption cost in California?

In this answer · 5 sections

California Courts' adult-adoption guide states that the filing charge is $20. StepParent Adoption 360's standard preparation price for the first adoptee is $349. That makes $369 for those two items, before additional expenses. An adult-adoption budget should therefore begin with the adult filing charge, rather than an estimated fee borrowed from a minor adoption or another civil case.

Understand what the California paperwork involves

The official California adult-adoption guide explains that counties may have local forms or samples. The paperwork includes an adoption agreement, a petition for approval, applicable spouse or partner consents and a proposed order. Ask your self-help center about local requirements before paying for extra documents or using child-adoption forms for an adult case.

The court guide permits filing where the adopting person or the adult to be adopted lives. Confirm the proper county and its filing procedure. Do not choose a court solely because you expect a shorter wait.

Check eligibility before ordering documents

The adopting person must be older than the adult being adopted. California also has limits involving adoption of unrelated adults and certain previous adoptions. If either person has a spouse or domestic partner, consent requirements or an applicable exception need attention. These are reasons to provide the actual circumstances at the beginning.

If the adoptee is developmentally disabled, ask about the special notice requirements. Do not treat an ordinary adult-adoption estimate as a promise that those additional steps can be skipped.

An investigation is not automatically required—or impossible

California Courts says there is no required investigation or report in the usual adult process, but the judge can request an investigation. Budget from what your court actually orders. The old claim that every adult adoption needs no investigation or background-related work was too broad.

Ask the clerk when a hearing can be set after correctly signed papers are filed, who should attend, and what records you should bring. The $20 filing charge does not establish a guaranteed hearing date or completion time.

Prepare your final cost checklist

Write down your county, the number of adoptees, any local documents, required signatures, expected certified copies and hearing travel. Discuss support, caregiving or estate issues with an attorney rather than treating a low filing charge as proof that the legal consequences are simple. The representation guide explains the different service scopes.

For another lawful filing jurisdiction, see the distinct Alaska and Texas cost guides. To begin a California case, start the adult-adoption questionnaire and keep your court charges separate from the preparation price.
