Adult Adoption FAQs: Consent, Court Steps and Legal Effects

The short answer: adult adoption is a short court process that makes a legal parent-child relationship official between two adults, most often a stepparent and the grown stepchild they raised. The key consent is the adult's own. The biological parents generally don't get a veto; in California, for example, they don't need to consent at all, and in states like Florida they simply receive notice of the hearing. Once the judge signs the order, you're legally parent and child, with effects on inheritance and family records that are worth understanding before you file.

What does adult adoption actually change?

It creates a legal parent-child relationship, just as a minor adoption does. For most families, that's the whole point: the stepparent who raised the child becomes their legal parent, often years after everyone already thought of it that way.

The legal effects come from your state's law. Inheritance is the one families ask about most. In Texas, for example, the adopted adult becomes the adoptive parent's child for all purposes, inherits from the adoptive parent like a biological child, and no longer inherits from the biological parents, nor they from the adoptee (Tex. Fam. Code § 162.507). Other states handle inheritance in their own way, so read your state's rule or ask an estate-planning attorney if inheritance is a main reason for adopting.

A court order also doesn't update everything on its own. Wills, beneficiary designations, insurance and agency records each need their own update, using certified copies of the adoption order.

Whose consent is required?

The adult being adopted. This is the consent that matters most. Texas says the court may not grant the adoption unless the adult consents in writing to be adopted by the petitioner (Tex. Fam. Code § 162.504).

Spouses. States differ here:

• Texas: if the person adopting is married, both spouses must join in the petition (§ 162.503). The court can grant the adoption to both spouses or, if they ask, to only one of them (§ 162.506).
• California: the adopting person's spouse or domestic partner must consent, and so must the adoptee's spouse or domestic partner, according to the California Courts self-help guide.
• Florida: the adult and the adult's spouse, if any, sign written consents, and the court can waive the spouse's consent for good cause (Fla. Stat. § 63.062(8)).

If you're a stepparent adopting your spouse's grown child, your spouse joining or consenting is usually exactly what you both want anyway.

Do the biological parents have to agree?

Generally, no. In an adult adoption the other biological parent is not asked for permission. California's court guide says plainly that the birth parents or adult children of the person being adopted don't need to consent, though the court may notify them about the hearing.

Some states build in notice. Florida Statutes § 63.062(8) requires written notice of the final hearing to the adult's parents, or proof that notice was served. Notice tells them the hearing is happening; it isn't a request for their approval. Keep their last known contact information handy in case your state requires it.

Are there age or residence rules?

Yes, and they come from the state where you file, not from general rules you may read online:

• California: the person being adopted must be 18 or older, and you must be older than they are. You file in the county where you live or where the adult lives. If your spouse or domestic partner has adopted an adult, you generally can't adopt another adult for one year unless that adult is the first adoptee's biological sibling.
• Texas: an adult residing in Texas may petition to adopt another adult (§ 162.501), in a district court or statutory county court with family-law jurisdiction in the county where the petitioner lives (§ 162.502). The adult adoption subchapter doesn't set an age-gap requirement.

Check your state guide for the rules where you live.

What is the court hearing like?

Short and usually warm. In California, a hearing is required, and the judge asks questions to confirm that you both understand the adoption and that it's in your interests. In Texas, both the petitioner and the adult must attend, though the court can waive attendance by written order for good cause if one of you can't be there (§ 162.505). Many families bring relatives and take photos afterward.

Does adult adoption affect government benefits?

Don't assume an adoption order starts or stops any benefit on its own. Each program (Social Security, veterans' benefits, health plans, pensions) applies its own rules about who counts as a child and what records it needs. If the adult being adopted, or anyone else in the family, receives a benefit, ask the agency that pays it how the adoption affects that benefit before you file. That one phone call answers the question for your exact situation.

Frequently Asked Questions

Can a stepparent adopt a stepchild who is already an adult?

Yes. Adult adoption is available for people 18 or older, and it's often simpler than adopting a minor because the adult gives their own consent.

Does the biological father have to consent to an adult adoption?

Generally, no. The adult's own consent is what's required. In California, birth parents don't need to consent; some states, such as Florida, require that the parents get written notice of the final hearing, which is a routine step and not a veto.

Does my spouse have to be part of the adult adoption?

Often, yes. In Texas, both spouses must join the petition if the person adopting is married. In California, the adopting person's spouse or domestic partner must consent, and so must the adoptee's.

Does the adopted adult inherit from the adoptive parent?

Usually, under the state's inheritance rules. In Texas, the adopted adult inherits from the adoptive parent like a biological child and no longer inherits from the biological parents. Check your state's rule and update wills and beneficiary forms either way.

Can the adult change their name as part of the adoption?

Often, yes. In California, an adult who wants the birth certificate to show a new name completes form VS-44. Other states handle name changes through the adoption order or a separate request; your state guide explains which.

Will the adoption change anyone's government benefits?

It depends on the program. Each agency applies its own rules, so ask the agency that pays the benefit before you file.
