Illinois allows you to change a baby's name as long as you're the baby's parent, have custody of the baby and have lived in Illinois for at least six months. The court must find that the change of name is beneficial for the child and will consider the wishes of both parents. If both parents consent to changing the baby's name, the process is relatively simple and handled through the Illinois Circuit County Court of the baby's residence.
Visit the Illinois Circuit County Court Clerk's office of the county the baby lives in. Ask for the Petition for Change of Name and the Order for Change of Name forms. Some counties refer to the order as the "Decree of Change of Name".

You need your name, your baby's current legal name and the name you want to give her. State your relationship to the child -- such as "mother" -- in the labeled spots. You, because you're applying on behalf of the child, are considered the "next of friend" on the form. Enter the date you will file the petition. You must run this notice in a newspaper at least six weeks before you file the petition, so give yourself enough time. You must file the petition on the day you entered on the notice. File the notice with the clerk and request three copies. Pay any associated fees.

Use the petition copy as a guide for completing the order form sections; the information must match. Fill in the baby's current name and the new name but don't sign or date the document.
Ask the court for a Notice of Motion form if you don't live with the other parent, and she won't sign the petition. Complete the motion, send a copy to the other parent by certified mail and file the motion in court.
