Illinois State Code:

Sec. 735 IL CS 5/21-101 Proceedings; parties. If any person who is a resident of this State and has resided in this State for 6 months desires to change his or her name and to assume another name by which to be afterwards called and known, the person may file a petition in the circuit court of the county wherein he or she resides praying for that relief. If it appears to the court that the conditions herein aftermentioned have been complied with and that there is no reason why the prayer should not be granted, the court, by an order to be entered of record, may direct and provide that the name of that person be changed in accordance with the prayer in the petition. The filing of a petition in accordance with this Section shall be the sole and exclusive means by which any person committed under the laws of this State to a penal institution may change his or her name and assume another name. However, any person convicted of a felony, misdemeanor criminal sexual abuse when the victim of the offense at the time of its commission is under 18 years of age, misdemeanor sexual exploitation of a child, misdemeanor indecent solicitation of a child, or misdemeanor indecent solicitation of an adult in this State or any other state who has not been pardoned may not file a petition for a name change until 2 years have passed since completion and discharge from his or her sentence. A petitioner may include his or her spouse and adult unmarried children, with their consent, and his or her minor children where it appears to the court that it is for their best interest, in the petition and prayer, and the court’s order shall then include the spouse and children. Whenever any minor has resided in the family of any person for the space of 3 years and has been recognized and known as an adopted child in the family of that person, the application herein provided for may be made by the person having that minor in his or her family. An order shall be entered as to a minor only if the court finds by clear and convincing evidence that the change is necessary to serve the best interest of the child. In determining the best interest of a minor child under this Section, the court shall consider all relevant factors, including:

(1) The wishes of the child’s parents and any person acting as a parent who has physical custody of the child.

(2) The wishes of the child and the reasons for those wishes. The court may interview the child in chambers to ascertain the child’s wishes with respect to the change of name. Counsel shall be present at the interview unless otherwise agreed upon by the parties. The court shall cause a court reporter to be present who shall make a complete record of the interview instantaneously to be part of the record in the case.

(3) The interaction and interrelationship of the child with his or her parents or persons acting as parents who have physical custody of the child, step- parents, siblings, step-siblings, or any other person who may significantly affect the child’s best interest.

(4) The child’s adjustment to his or her home, school, and community. (Source: P.A. 88-25; 89-192, eff. 1-1-96; 89-462, eff. 5-29-96.)

(b) The publication requirement of subsection (a) shall not be required in any application for a change of name involving a minor if, before making judgment under this Article, reasonable notice and opportunity to be heard is given to any parent whose parental rights have not been previously terminated and to any person who has physical custody of the child. If any of these persons are outside this State, notice and opportunity to be heard shall be given under Section 21-104. (Source: P.A. 87-409.)
