The Illinois name change process starts in circuit court, costs between $300 and $500, and takes four to eight weeks from filing to final order

You file a petition in the circuit court of the county where you live, pay the filing fee, publish a notice in a local newspaper for two weeks, and attend a brief hearing where a judge signs off on the change. The court then issues a certified order, which you use to update your Social Security card, driver's license, and other documents. You do not need a lawyer, though one can speed the process if complications arise.

Illinois allows name changes for any reason — you do not have to explain why you want a new name. The main requirements are that you must be a resident of Illinois, at least 18 years old, and not changing your name to commit fraud or evade a legal obligation like child support or a criminal sentence.

Key Takeaways

  • You file your petition in the circuit court of your home county, and the filing fee ranges from $300 to $500 depending on the county.
  • Illinois requires you to publish notice of your name change in a newspaper for two consecutive weeks before the court hearing.
  • The judge will hold a brief hearing, usually lasting only a few minutes, and will grant the change unless you are trying to evade a legal obligation.
  • After the court issues your final order, you must update your name with Social Security, the Secretary of State, and your bank or employer separately — the court order does not do this automatically.

Where to file and what forms you need

Contact the circuit court clerk's office in the county where you live. You can find the correct courthouse and clerk contact information on the Illinois Courts website or by calling your county courthouse directly. Ask the clerk for the petition form for a name change — the exact title varies slightly by county, but it is usually called a "Petition for Change of Name" or "Petition to Change Name."

The petition asks for your current legal name, the name you want, your date of birth, your current address, and the reason for the change (though you can write "personal reasons" if you prefer not to be specific). You will also need to provide proof of Illinois residency, such as a utility bill, lease, or driver's license. Some counties require you to submit the petition in person; others allow you to mail it. Call ahead to confirm your county's process.

The newspaper publication requirement

After you file your petition, the court will direct you to publish a notice of your name change in a newspaper of general circulation in your county. This notice must run for two consecutive weeks. The newspaper will charge you a fee, usually $50 to $150, depending on the publication and county.

You do not get to choose any newspaper — it must be one that the court approves or one that meets the state's definition of a newspaper of general circulation. The clerk's office can tell you which newspapers in your county may have access to. After the two weeks are up, the newspaper will give you an affidavit of publication, which you must bring to your court hearing as proof that the notice ran.

The court hearing and judge's decision

The court will schedule a hearing, usually four to eight weeks after you file. The hearing is brief — typically five to ten minutes. You will stand before a judge, confirm your identity and current name, state the name you want, and explain briefly why you are requesting the change. The judge will ask whether you are changing your name to avoid a legal obligation or commit fraud. If you answer no, the judge will almost always grant the change on the spot.

You do not need a lawyer present, and you do not need to bring witnesses. Bring your filed petition, the affidavit of publication from the newspaper, a photo ID, and proof of residency. If you cannot attend the hearing, some judges will allow you to appear by phone or video conference — ask the clerk when you receive your hearing notice.

Getting your certified court order

After the judge signs the order, the clerk will issue you certified copies. Order at least three to five certified copies of the final order — they cost $5 to $15 each depending on the county. You will need one for Social Security, one for your state ID or driver's license, and one for your bank or employer. Keep the originals in a safe place and use the certified copies for official requests.

The court order is the legal proof of your name change. Without it, government agencies and financial institutions will not recognize your new name. Do not rely on photocopies — most agencies require the certified version with the court seal.

Updating your Social Security card and state ID

Once you have your certified court order, visit your local Social Security office or go online to ssa.gov to request a new Social Security card in your new name. Bring your certified court order, a photo ID, and proof of citizenship (passport, birth certificate, or naturalization papers). The new card usually arrives within two weeks.

Next, visit a Secretary of State facility to renew your driver's license or state ID card. Bring your certified court order, your current driver's license, and proof of residency. You may have to pay a renewal fee, typically $20 to $30. If your license is not expiring soon, you can still renew it early to reflect your new name.

Updating banks, employers, and other institutions

After you have your new Social Security card and driver's license, contact your bank, credit card companies, employer, and insurance providers to update your name on file. Bring a copy of your certified court order and your new ID. Most institutions can process the change within one to two business days.

You should also update your name with the U.S. Postal Service if you want mail addressed to your new name to be delivered. Visit usps.com or your local post office to file a change of address or name update. Update your voter registration through your county clerk's office and your passport through the U.S. State Department if you have one.

Costs and timeline summary

The total cost of a name change in Illinois ranges from $350 to $700, depending on your county and which certified copies you order. The filing fee is $300 to $500, newspaper publication costs $50 to $150, and certified copies cost $15 to $75 total. Some counties charge lower fees if you have a low income — ask the clerk whether your county offers a fee waiver.

The entire process from filing to receiving your final court order takes four to eight weeks. The longest wait is usually the two-week newspaper publication period plus the time it takes the court to schedule your hearing. After you receive the order, updating your Social Security card and driver's license takes another two to four weeks.

Frequently Asked Questions

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

No. The process is straightforward enough that most people handle it without legal help. A lawyer can be useful if you are changing your name while involved in a custody dispute, criminal case, or debt collection — situations where the court may scrutinize the reason for the change more closely.

Can I change my child's name?

Yes, but the process is different. You file a petition on behalf of your minor child in circuit court. If both parents agree, the process is faster. If only one parent is filing, the other parent must be notified and given a chance to object. The court will hold a hearing and decide based on the child's best interests.

What if I was convicted of a crime or owe child support?

The court will not grant a name change if it believes you are doing so to evade a criminal sentence, probation, or a child support obligation. You must disclose any criminal history or outstanding child support when you file your petition. The judge will decide whether the change is being sought in good faith.

How long does the name change stay valid?

Once the court issues the order, your name change is permanent and valid for life. You do not need to renew it or file anything again. The certified court order is your proof of the change and remains valid indefinitely.

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

Yes. You can file a new petition to change your name back to your original name or to any other name you choose. You will go through the same court process, pay the same fees, and publish the notice again. There is no waiting period or limit on how many times you can change your name.
