File Your Forms & Schedule a Hearing

File your forms in the Circuit Clerk’s office. Your Request for Name Change (Adult) has to be notarized prior to filing. The Clerk requires a filing fee in cash, money order, or credit card. No personal checks are accepted. The Circuit Clerk will give you a date to appear in court to hear your Request for Name Change (Adult). This date can be any day Monday through Thursday at 9:00 am or 1:30 pm.

Publish Your Intention to Change Your Name

Next, you have to publish your intention to change your name in a newspaper of general circulation in Lake County. The Circuit Clerk’s office will forward your Notice of Publication to the newspaper. There is a publication cost, which the newspaper will contact you about, or you can contact the newspaper. The Notice has to be published for three consecutive weeks after the Request for Name Change (Adult) is filed, with the first insertion at least six weeks before your court date. After publication is completed, the newspaper will mail you a Certificate of Publication. Make sure you bring this Certificate with you to the Court hearing.

On the day of your court hearing, plan to arrive at the assigned courtroom at least 15 minutes prior to the scheduled start time. Check-in with the Clerk in the courtroom, and your case will be called by the judge.
