The Illinois Petition for Name Change (Minor) is a legal document that is used to request a name change for a minor under the age of 18. The petition must be filed in the circuit court in the county where the minor resides. The petition must include the minor's current name, the proposed name change, the reason for the request, the minor's date of birth, and the names of both parents or legal guardians. There are two types of Illinois Petition for Name Change (Minor): a joint petition and an individual petition. The joint petition is when both parents jointly agree to the name change and submit a single petition to the court. An individual petition is when one parent submits a petition to the court without the other parent's agreement.
