Step by step

1
Complete the minor name-change forms from the Wyoming Judicial Branch — the Petition and Affidavit for Change of Name of a Minor Child and the Notice of Publication.
2
If the other parent agrees but is not filing with you, have that parent sign the Parental Consent to Name Change of Minor Child form and file it with the Clerk of District Court.
3
File the petition, pay the filing fee (about $120, confirm with the clerk), and publish the notice in a county newspaper once a week for four consecutive weeks.
4
Attend the hearing; the judge decides based on the best interest of the child, and both parents have the right to be notified of the request.
5
Obtain the signed order and certified copies, then update the child's Social Security record, birth record, and school and passport records.
