Illinois How to Change Children's Names is a legal process that allows individuals to update a child's name. This process is most often used when a child is adopted, when a parent wishes to change a child's name due to marriage, or when a child wishes to change their name to something more culturally or personally meaningful. The process includes filing a Petition for Change of Name with the local Circuit Court, providing the court with a certified copy of the child's birth certificate, and attending a hearing. Depending on the jurisdiction, the petitioner may also need to give notice of the petition to other family members or publish in the local newspaper. There are two types of Illinois How to Change Children's Names: Standard Change of Name and Name Change for a Minor. The Standard Change of Name is used for adults and requires getting consent from the other parent or providing proof of legal guardianship, while the Name Change for a Minor is used for children and requires proof of consent from both parents or legal guardians.
