The Two Routes to a Legal Name Change in Illinois

In Illinois, you change your name through the circuit court in the county where you live. There are two separate processes: one for adults and one for minors. Both require filing paperwork with the court, paying a filing fee, and in most cases attending a brief hearing where a judge approves the change. The process takes roughly four to eight weeks from filing to final order, though timing varies by county.

An adult can change their name for any reason—a marriage, divorce, personal preference, or religious conviction. A parent or guardian can change a minor's name, but the minor must be present at the hearing in most cases, and if the minor is old enough to understand, the court may ask them directly whether they consent. Both processes result in a court order that you can then use to update your name with the Social Security Administration, the Illinois Secretary of State, banks, employers, and other institutions.

Key Takeaways

  • Adults file a Petition for Change of Name in the circuit court of their home county; minors' name changes require a parent or guardian to file on their behalf.
  • You must pay a filing fee (typically $200 to $300, depending on the county) and serve notice on anyone who might object, such as a non-custodial parent.
  • Most cases result in a hearing before a judge, though some counties allow uncontested cases to be approved on paper without appearing in court.
  • After the judge signs the order, you receive a certified copy that you use to update your Social Security number, driver's license, and other documents.

Filing a Name Change Petition as an Adult

Start by obtaining the correct form from the circuit court clerk's office in your county. The form is called a Petition for Change of Name, and most Illinois counties provide it free on their websites or in person at the courthouse. Fill in your current legal name, the name you want, and your reason for the change (though you are not required to give a detailed reason—"personal preference" is sufficient).

Attach a copy of your birth certificate or other proof of identity to the petition. Some counties also require a background check or fingerprinting; call the clerk's office to ask what your county requires. Once the petition is complete, file it with the circuit court clerk along with the filing fee. The fee varies by county but typically ranges from $200 to $300. Ask the clerk whether your county allows uncontested cases to proceed without a hearing, or whether you must appear before a judge.

If you have been convicted of a felony, particularly one involving fraud or identity theft, the court may deny your petition or require you to show that the name change is not being sought to evade criminal liability. Be honest about your history; the court will conduct a background check anyway.

Serving Notice and Handling Objections

After you file, you must serve written notice of the petition on anyone who might have a legal reason to object. For an adult, this typically means a spouse (if you are married), a creditor you are trying to evade, or anyone else the court deems relevant. In most uncontested cases, you only need to serve the State's Attorney's office in your county. The clerk will tell you exactly who must be served and how.

Service usually means delivering a copy of the petition by certified mail or in person. Keep proof of service—a signed receipt or an affidavit—and file it with the court before the hearing date. If no one objects within the time allowed (usually 30 days), the case is considered uncontested and the judge will likely approve it.

If someone does object, you will attend a hearing where both sides present their case. Objections are rare in adult name-change cases unless there is a criminal history or a creditor trying to prevent the change. If an objection is filed, the court will set a hearing date and notify you.

Name Changes for Minors

A parent or legal guardian files a Petition for Change of Name of Minor in the circuit court of the county where the minor lives. The form is similar to the adult petition but includes the minor's current name, the proposed name, and the parent's or guardian's name and relationship to the child.

You must serve notice on both parents if both are living and have parental rights, even if one parent does not have custody. If the other parent objects, a hearing will be held. The minor must usually be present at the hearing; the judge may ask the child directly whether they consent to the name change, especially if the child is old enough to understand. In Illinois, there is no set age at which a minor's consent becomes required, but judges typically ask children age 12 and older.

If one parent has sole custody and the other parent's whereabouts are unknown, you can ask the court to proceed without serving that parent. Bring documentation of your custody order and evidence that you have made a reasonable effort to locate the other parent.

What Happens at the Hearing

If your case goes to a hearing, you will appear before a judge in the circuit court. Bring your original petition, proof of service, your birth certificate or ID, and any other documents the court requested. The hearing is usually brief—often just 5 to 10 minutes. The judge will ask you why you want to change your name, verify that you are not doing so to commit fraud or evade a legal obligation, and confirm that you understand the change is permanent.

You do not need a lawyer, though you may bring one if you wish. If the judge approves the petition, they will sign an order granting the name change. You will receive a certified copy of the order, usually within a few days. This certified copy is your proof of the legal name change and is what you will need to update your name with other agencies and institutions.

If the judge denies the petition, they will explain their reason. You can file a new petition later if circumstances change, or you can appeal the decision, though appeals are uncommon in name-change cases.

Updating Your Name After the Court Order

Once you have the certified court order, use it to update your name with the Social Security Administration, the Illinois Secretary of State (for your driver's license or state ID), and any banks, employers, insurance companies, or other institutions that have your name on file. Start with Social Security and the Secretary of State, because those documents are often required to update your name elsewhere.

Visit your local Social Security office or call 1-800-772-1213 to request a new Social Security card in your new name. Bring the certified court order, your current Social Security card, and a photo ID. There is no fee for a replacement card.

For your Illinois driver's license or state ID, visit a Secretary of State facility with your certified court order, your current license, and proof of your new name (the court order itself usually suffices). You may be able to renew online or by mail, but a name change typically requires an in-person visit. There is a fee for a replacement license, usually around $20.

Timeline and What to Expect

From the date you file your petition to the date the judge signs the order, expect four to eight weeks. The exact timeline depends on how busy your county's court is and whether your case is uncontested. Uncontested cases often move faster—sometimes in as little as two to three weeks. If someone objects or if the court requests additional information, the process can take longer.

After the judge signs the order, you will receive a certified copy within a few business days. You can then begin updating your name with other institutions. Most agencies process name changes within one to two weeks of receiving your court order and completed forms.

Keep multiple certified copies of your court order—at least three or four. Some institutions will not return the copy you submit, and you may need to provide proof of the name change to multiple agencies over time. You can order additional certified copies from the circuit court clerk for a small fee, usually $5 to $10 per copy.

Frequently Asked Questions

Do I need a lawyer to change my name in Illinois?

No. The process is straightforward enough that most people file the petition themselves. A lawyer can help if your case is contested or if you have a criminal history that might complicate approval, but for a straightforward, uncontested name change, legal representation is not necessary.

Can I change my name if I have unpaid debts or a criminal record?

A criminal record does not automatically prevent a name change, but the court will review your background. If you have been convicted of fraud or identity theft, the judge may deny your petition if they believe the name change is being sought to evade criminal liability or defraud creditors. Be honest about your history; the court will find out anyway through a background check.

How much does it cost to change my name in Illinois?

The filing fee ranges from $200 to $300 depending on your county. You may also pay a small fee for certified copies of the court order (usually $5 to $10 per copy). If you hire a lawyer, legal fees vary but typically range from $300 to $800 for an uncontested case.

What if the other parent refuses to consent to my child's name change?

If the other parent objects, the court will hold a hearing. The judge will consider what is in the child's best interest. If you have sole custody, your preference carries more weight. If custody is shared, the judge may require both parents to agree, or they may approve the change anyway if they determine it serves the child's interests.

Can I change my name back if I change my mind later?

Yes. A name change is not permanent in the sense that you cannot reverse it. You can file a new petition to change your name back to your original name or to any other name you choose, following the same process. There is no waiting period between name changes.
