What is ATJ 8001.1?
The Notice of Change of Address (Form ATJ 8001.1, revision 07/25) is the Illinois Supreme Court-approved statewide form that a party or attorney in an Illinois Appellate Court appeal uses to give notice of a new mailing address, a new email address, or both.
The form states that it is approved by the Illinois Supreme Court and is required to be accepted in the Illinois Appellate Court. The Supreme Court Commission on Access to Justice approved it, and the Illinois courts list it among the approved statewide appellate forms with the note "Approved 07/2025". The courts also publish a companion guide titled "How to File a Notice of Change of Address".
The form has four pages:
- A caption with the appellate district, the Appellate Court case number, the trial court, the parties and the judge.
- Item 1, the person and the information being updated, and Item 2, the person's role in the appeal.
- A Proof of Delivery section (A, B and C) showing how and when the notice was sent to each other party or lawyer.
- A certification under 735 ILCS 5/1-109, with a section for a lawyer completing the form for a client.
It is a notice of an address change in an existing appeal, not a new filing that starts a case.
Who needs to file ATJ 8001.1?
The main group is anyone who is a party in an Illinois Appellate Court appeal and whose mailing address, email address, or both have changed. Item 2 asks you to check one box: Appellant (the party who filed the appeal), Appellee (the party responding to it), Attorney for a named client, or Other.
A licensed attorney may complete the form for a client. The last page has a section, to be completed only by a licensed attorney, with the client's name, the lawyer's name, attorney number, phone, firm, email and address. Self-represented people check I am completing this form for myself and give their own address, telephone number and email address, if they have one.
The form also says you must serve the other party. The Proof of Delivery section must be completed, and if the other party has a lawyer, you enter the lawyer's information. If you are sending the notice to more than 3 people or lawyers, you complete an Additional Proof of Delivery form as well.
When to file ATJ 8001.1
Complete this form when your mailing address, email address, or both change while you are a party or attorney in an Illinois Appellate Court appeal. The form prints no due date or filing window of its own. Section A, B and C each ask for the date and time you send the notice to the other parties, so you complete the Proof of Delivery on the day you serve them. The form also warns people who receive court documents by email to check their email every day so they do not miss documents from the other parties or from the court.
Documents you need
- Additional Proof of Delivery form: complete and file it with this form only if you are sending the Notice of Change of Address to more than 3 people or lawyers.
How to fill out ATJ 8001.1
Enter the appellate court caption
Below "In the Appellate Court of Illinois," enter the appellate district where the appeal was filed, then the Appellate Court Case No. At the right, enter the trial court county, trial court case number and the trial judge's name.
Name the parties and mark roles
If the trial court case name began with "In re" (for example, "In re Marriage of Jones"), enter that phrase. Otherwise enter the plaintiff/petitioner and defendant/respondent names as in the trial court documents, and check Appellant for the party who filed the appeal and Appellee for the responding party.
Enter your name in Item 1
In Item 1, enter your first, middle and last name. Add the business or firm name if applicable.
Select the information you are updating
Check the box for New Mailing Address and complete the street, apartment, city, state and ZIP. Check New Email Address and enter it if your email changed. If both changed, complete both.
Check your role in Item 2
Check only one box: Appellant, Appellee, Attorney for (with the client's name) or Other (with a description).
Sign and add your contact details
If you complete the form on a computer, sign by typing your name after /s/. If you complete it by hand, sign and print your name. Fill in your street address, city, state, ZIP, email, telephone, and firm name and attorney number if any.
Complete Proof of Delivery section A
Enter the name, mailing address and email address of the person you are serving under Rule 11, using the lawyer's information if that person has a lawyer. Then check how you are sending it: email (not through an EFSP), an approved EFSP, or, if there is no email, mail or third-party carrier, hand delivery, or mail from a prison or jail.
Enter the sending date and time
Under "This document will be sent on," enter the date (month, day, year) and the time, including AM or PM. Repeat this in each of sections A, B and C that you use.
Complete sections B and C if needed
If you are not sending the notice to another person, check the first box in B and C and leave the rest blank. Otherwise check the second box and enter that person's or lawyer's name, address, email and delivery method.
Add the extra form for more than 3
If you are sending the notice to more than 3 people or lawyers, check the box saying you completed an Additional Proof of Delivery form and file that form with this one.
Complete the certification and lawyer section
On page 4, sign by typing /s/ and your name if online, or sign and print by hand, and give your phone, email and address. Check I am completing this form for myself, or, if you are a licensed attorney, check the lawyer box and complete the client and lawyer details.
Review and download the completed PDF
Check that the case number appears on every page and that the Proof of Delivery matches how and when you serve each person. Download or print the completed PDF from FillingPDF and, if you e-file, flatten it first.
How to submit ATJ 8001.1
The form is built for two steps: filing the completed notice in your appeal, and serving it on the other parties under Rule 11. The form itself prints no court address or portal, so check the Illinois courts' guide, "How to File a Notice of Change of Address", for filing details.
- E-filing: the Illinois courts' page says you must first save or download the form as a PDF before you begin, because progress is lost if you fill it out on a webpage. To e-file you must "flatten" the form so it cannot be changed: in Adobe Acrobat or Reader, choose File, Print, then "Adobe PDF" or "Print to PDF" and save the result. Open the flattened file to check that it looks filled out before you e-file it.
- Serving the other parties (Proof of Delivery, A to C): if you and the recipient both have email, you must use email (not through an EFSP) or an approved electronic filing service provider (EFSP). Otherwise you may send it by mail or third-party carrier with postage or charge prepaid, by personal hand delivery, or by mail from a prison or jail.
For hand delivery, you can deliver only to the party, the party's family member over 13 at the party's residence, the party's lawyer, or the lawyer's office. FillingPDF lets you fill out and download the PDF; submission follows the channels above.
Common mistakes to avoid
- Filling out the form on a webpage without first saving or downloading it as a PDF; the Illinois courts warn that progress is lost.
- E-filing a form that has not been flattened, or not opening the flattened file to confirm it looks filled out.
- Skipping the Proof of Delivery section; the form says you must serve the other party and complete it.
- Choosing mail or hand delivery when both you and the recipient have email addresses; you must use one of the two electronic options.
- Hand delivering the notice to someone other than the party, a family member over 13 at the party's residence, the party's lawyer, or the lawyer's office.
- Checking more than one box in Item 2; the form says to check only one.
- Entering the other party's own address when that party has a lawyer; the form requires the lawyer's information.
- Sending to more than 3 people without completing and filing the Additional Proof of Delivery form.
- Leaving the Appellate Court Case Number blank at the top of pages 2, 3 and 4.

What is a notice of change of address in the Illinois Appellate Court?
It is Form ATJ 8001.1, a statewide form approved by the Illinois Supreme Court that a party or attorney in an appeal uses to report a new mailing address, a new email address, or both. The form states it must be accepted in the Illinois Appellate Court.
Who has to serve the notice on other people?
You do. The Proof of Delivery section says you must serve the other party and complete the section. Enter the other party's name, address and email under Rule 11, or the lawyer's information if that party has a lawyer, and use sections B and C for additional recipients.
How do I sign the Notice of Change of Address online?
If you complete it on a computer, sign by typing your name after /s/. If you complete it by hand, sign and print your name. The certification under 735 ILCS 5/1-109 applies either way: knowingly making a false statement on the form is perjury.
Can I mail the notice if the other party has an email address?
No. If you and the person you are sending it to both have an email address, you must use email (not through an EFSP) or an approved electronic filing service provider. Mail, hand delivery or mail from a prison or jail is allowed only if one of you has no email.
Who can I hand deliver the notice to?
Only to the party, the party's family member over 13 at the party's residence, the party's lawyer, or the lawyer's office. Enter the full address where you deliver it in the hand-delivery line of the Proof of Delivery section.
What if I am sending the notice to more than 3 people?
Check the box saying you are sending it to more than 3 people and have completed an Additional Proof of Delivery form, then file that form with the Notice of Change of Address. Sections A, B and C cover only three recipients.
How do I prepare the form for e-filing?
Save the form as a PDF first, fill it out, then flatten it so it cannot be changed. In Adobe Acrobat or Reader, use File, Print and choose Adobe PDF or Print to PDF, then open the saved file to confirm it looks filled out before you e-file.

Yes. You can fill out the PDF online on FillingPDF and download or print it. FillingPDF is an independent service that does not file the form with the court or serve it on other parties; you do that through the channels described by the Illinois courts and the form.
