How to Change a Minor Child’s Name in Illinois

To change a minor child’s name in Illinois, a parent or legal guardian files a petition in the circuit court of the county where the child lives, serves notice on the other parent, publishes a newspaper notice for three consecutive weeks, and appears at a hearing where a judge must find by clear and convincing evidence that the change is necessary for the child’s best interest.¹ A child cannot file for themselves; the parent handles the case on the child’s behalf because minors lack legal capacity to file lawsuits in Illinois.² From filing to final order usually runs two to three months because of the publication timeline.

Residency and Who Can File

The child must have lived in Illinois for at least six consecutive months before you file.¹ File in the circuit court for the county where the child currently resides. There is no shortcut on the six months. If you recently moved to Illinois, the clock has to run before the court can hear your petition.

The parent or guardian with legal custody signs the petition on the child’s behalf.

What Goes in the Petition

Illinois uses a statewide standardized petition approved by the Illinois Supreme Court, so you do not draft your own version. The form asks for the child’s current legal name, the proposed new name, the child’s home address, how long the child has lived in Illinois, and the child’s state or country of birth.³

The petition includes a sworn statement about any criminal record of adults covered by the petition, including unresolved arrests or pending charges. If the answer is yes, the clerk forwards a copy to the State’s Attorney and the Illinois State Police, and you may need to update your criminal history transcript before the hearing can go forward.³ False information on the sworn petition can lead to dismissal or criminal penalties.

Prepare a blank Order for Name Change for the judge to sign if the petition is granted. That is a separate standardized form on the Illinois Courts website, and you need one per child.⁴

Notifying the Other Parent

Every parent whose parental rights have not been terminated must receive actual notice and an opportunity to be heard before a judge can enter a name change order for a minor. The same applies to anyone allocated parental responsibilities under the Illinois Marriage and Dissolution of Marriage Act.⁵ This requirement is strict. Cutting corners here is the most common way a petition stalls.

The simplest path is a written consent signed by the other parent. When both parents agree, the hearing is routine.

If the other parent will not consent, serve them with formal notice of the petition and the hearing date so they can appear and object. If they live outside Illinois, you can serve them by personal delivery, by the service rules of the state where they live, or by any form of mail with a return receipt. The notice has to arrive at least 10 days before the hearing.⁶

If you genuinely cannot locate the other parent after reasonable efforts, you can use publication as an alternative form of notice; the circuit clerk can forward a notice of publication to a local newspaper. A judge who sees that you did not make a real effort to find the other parent will not accept it.

Publishing the Newspaper Notice

Separate from notifying the other parent, Illinois requires you to publish a notice of the name change in a newspaper. The notice runs once a week for three consecutive weeks after you file, and the first insertion has to appear at least six weeks before your hearing.⁷ The notice names the child’s current name, the proposed name, and the hearing date, and the parent or guardian signs it.

Which newspaper depends on where the child lives. In a municipality within a county of fewer than two million people, publish in a newspaper from that municipality. In a county of two million or more (Cook County), publish in any newspaper from the county. After the three weeks finish, the newspaper issues a certificate of publication, which you bring to the hearing.

You pay the newspaper directly. Costs range from roughly $50 to several hundred dollars depending on the publication.

Asking to Skip Publication for Safety

If publishing the name change would put the child or the petitioner at risk of physical harm or discrimination, you can ask the court to waive publication. Illinois provides a standardized Motion to Waive Notice and Publication form for this.⁴ A judge is more likely to grant the waiver when the petitioner is or has been protected under an order of protection, a stalking no contact order, a civil no contact order, or a similar protective order from another state.

When the waiver is granted, the court also impounds the case file so it is sealed from public view. The Illinois Supreme Court has approved separate Motion to Impound and Order to Impound forms for minor cases.⁴ Raise the safety concern at the start of the case rather than after publication has begun.

Filing Fees and Waivers

Illinois requires electronic filing for civil cases, so you submit the petition through one of the state’s certified e-filing service providers.⁸ Filing fees vary by county; your local circuit clerk posts the current amount.

If you cannot afford the fee, submit an Application for Waiver of Court Fees. Illinois uses a sliding scale based on the federal poverty level:

Full waiver at household income at or below 125% of the federal poverty level
75% waiver above 125% through 150%
50% waiver above 150% through 175%
25% waiver above 175% through 200%

You also qualify for a full waiver regardless of income if you receive certain means-tested benefits such as Supplemental Security Income, TANF, SNAP, or General Assistance.⁹ The waiver applies only to court fees. It does not cover the newspaper publication cost, which goes to the publisher.

The Hearing and the Best Interest Standard

At the hearing, the judge applies a demanding standard: clear and convincing evidence that the name change is necessary to serve the child’s best interest.¹ “Necessary” is the operative word. You are not showing the change would be nice or convenient; you are showing the child’s welfare requires it.

The statute identifies four factors the judge weighs:

Each parent’s wishes, and the wishes of anyone with physical custody, including step-parents and siblings
The child’s own wishes and reasons. The judge can interview the child privately in chambers with a court reporter present to make a full record.
How the child interacts with parents, step-parents, siblings, and other important people in the child’s life
How well the child is adjusted to home, school, and community

When both parents agree and the child wants the change, approval is close to automatic. Contested cases are harder. If one parent objects, the judge looks closely at whether the change actually serves the child or primarily serves the petitioning parent. Older children’s own views carry more weight.¹

Come to the hearing ready to explain the reason in concrete terms tied to those four factors. A vague claim that the change “would be better” rarely holds up when the other side is pushing back.

Updating Your Child’s Records After the Order

Once the judge signs the order, get certified copies from the circuit clerk right away. There is a per-copy fee that varies by county. Different agencies each want their own original, so order enough copies the first time rather than returning to the clerk repeatedly.

Social Security Card

Update the Social Security card in person at a Social Security office with the court order. Social Security accepts only original documents or copies certified by the issuing agency; photocopies and notarized copies will not do.¹⁰ If the name change happened more than four years ago, or if Social Security cannot match the child’s identity from the court order alone, you may need an identity document in the child’s prior name. Filing on behalf of a minor can also require documentation of custody or parental responsibility. There is no fee.

Birth Certificate

A legal name change counts as a major correction to the birth certificate and goes through the Illinois Department of Public Health, Division of Vital Records. Submit an Affidavit of Correction with the certified court order and a valid government-issued photo ID. Contact IDPH for current fees and processing times. The court order alone does not update the birth certificate; the IDPH process is separate.

Other Records

You will likely need to update the child’s school records, health insurance, passport if one exists, and any bank accounts in the child’s name. Each institution has its own process, but almost all will ask for a certified copy of the court order.
