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

Yes, you can ask for your stepchild to keep their current last name in a Wyoming stepparent adoption. Adoption is about who the child's legal parent is, and the name is a separate choice you can raise with the court. Because the data on how Wyoming handles names is limited, the District Court clerk in your county can confirm exactly how the name appears on the forms and the final decree.

Where the name decision happens: A Wyoming adoption starts with a petition filed in District Court (Wyo. Stat. § 1-22-104(a)). That is where you tell the court about the adoption you are asking for, so it is the natural place to state the name your child will use afterward. Whether you keep the current last name, use yours, or combine them, settle it before you file so the paperwork is consistent.

Your options to think through:

• Keep the current last name. This can suit an older child who strongly identifies with their name, or a family that wants to honor the other parent's side, especially if that parent has died.
• Take your last name. Many stepfamilies like having everyone share a name.
• Combine the names. A hyphenated name can reflect both sides of the family.
• Change a first or middle name too. Ask the clerk how to include this in the petition.

Involve your child: Wyoming sets the age at which a child's consent to the adoption is required at 14 (Wyo. Stat. § 1-22-109). That consent is about the adoption itself, not the name, but it shows the law takes an older child's voice seriously. Whatever your child's age, talking with them about the name before you file can make the process feel more like theirs. There is no pressure either way, and you can choose what fits your family.

Timing and records: Wyoming stepparent adoptions typically take 3-6 months. You will want the name settled early so it is consistent on every document. The name on your child's updated records is handled through Wyoming Vital Statistics Services. Ask the District Court clerk what to expect on the decree and what steps follow for the birth certificate.

Other requirements still apply. Choosing to keep the last name does not change the rest of the process. For example, the adoptive parent must have lived in Wyoming for 60 days immediately before filing (Wyo. Stat. § 1-22-103). If your situation is complicated, such as a contested case or a parent who cannot be found, the name question may depend on the facts. The clerk or a Wyoming attorney can advise on that.
