Can my stepchild keep their current last name after adoption in California?

Yes, your stepchild can keep their current last name after a stepparent adoption in California. The name change is something you include only if you want it, and the adoption itself is about the legal parent-child relationship, not about the name.

What California's process offers: A name change can be part of the adoption in the Superior Court of your county, at no additional court cost. You can include one if your family wants it, and you don't need to if you don't. The court filing fee range is $200-$500, and the typical total cost is under $600, with or without a name change.

Choices to think through:

• Keep the current name: You would ask for no name change, and the child's name stays as it is.
• Take your last name: This gives the child the same surname as the rest of the household.
• Combine names: Some families want to keep a connection to both sides.
• Change a first or middle name: This is also a personal decision, and the Superior Court clerk in your county can confirm how the court handles any particular request.

Why families keep the current name:

• An older child may strongly identify with their name.
• The child may ask to keep it.
• The family may want to honor the other side of the child's family, especially if a parent has passed away.
• Keeping it avoids confusion with school records, friends and activities.
• The child may want to decide about a change later, on their own terms.

Involve your child: In California, a child who is 12 or older must consent to their own adoption (Cal. Fam. Code § 8602). The consent is about the adoption itself, but it is a natural moment to talk about names too. Even with a younger child, hearing how they feel can help the whole family feel good about the decision.

Records and paperwork: Birth records are handled by the California Department of Public Health Vital Records. If you keep the current name, it is still worth asking the Superior Court clerk and Vital Records how updated records and any school, medical or Social Security paperwork will be handled for your situation. If your case involves something unusual, such as a contested adoption or an unknown parent, an attorney can advise you on that specific issue.

Timing: The typical stepparent adoption timeline in California is about 3 months. The name question is settled in your petition, so you can decide before you file, and you can talk it over as a family first.

There is no right answer. Keeping the name, changing it or blending it is a personal family decision.
