A Summons is a court form that tells a person or business they are being sued. When you file a lawsuit, you must notify the other party by having the Summons and a copy of your Complaint or Petition delivered to them. This is called serving the other party. Serving the Summons gives them a chance to respond and take part in the case.
If the Summons is not served correctly, the court may dismiss your case.
Fill out a Summons and file it with your Complaint or Petition at the circuit court clerk’s office in the county where your case is filed. You will need the names and addresses of everyone you are suing. Learn more about starting a lawsuit.
You can file the Summons at the same time you file your Complaint or Petition, or you can file it afterward. In most counties, you must file your forms electronically (e-file) unless you qualify for an exemption.
You can use the general civil Summons for most civil cases, such as cases about personal injury or property damage. But some cases use a different Summons. These include divorce, eviction, small claims, and orders of protection. You can find these summons on the Illinois Courts website.
Note: If you are filing a case in Cook County and want to use a private process server, you must pay an extra $5 per party when you file your documents. The e-filing system does not make this clear, so you need to find and select this fee option. If you do not, the circuit court clerk may reject your filing.
After you file your forms, the circuit court clerk will “issue” the Summons . This means the clerk puts a court seal on the form. Once the Summons is issued, you can arrange to serve the other party. You do this by having the Summons and a copy of your Complaint or Petition delivered to them. Each person or business you are suing must be served.
You cannot serve the papers yourself. It must be done by one of these:
- The sheriff
in the county where the defendant
lives
- This is the most common way to serve a summons.
- If your fee waiver is approved, the fee for having the sheriff serve your summons should be covered.
- A licensed private process server
- To find a professional process server, you can search online. The National Association of Professional Process Servers also has a directory.
- Licensed private process servers are private businesses and charge a fee. Contact the specific business to ask about their service fees.
- An unlicensed process server
- This could be anyone over the age of 18 who is not involved in the case.
- You must get permission from the judge to use an unlicensed process server.
Give the sheriff or process server:
- At least one copy of the Summons
- One copy of the Complaint or Petition
- A blank Proof of Service of Summons form
You need one full set of these forms for each person or business being served. If you mail your documents to the sheriff, you can use the Letter to the Sheriff form. You can find all required forms on the Illinois Courts website.
In most cases, whoever serves the papers may do one of the following:
- Personally hand the Summons and Complaint or Petition to the defendant anywhere, or
- Go to the defendant’s home and give the Summons and Complaint or Petition to someone who lives there and is at least 13 years old. A copy must also be mailed to the defendant at that address.
Different service rules apply if you are serving a corporation, partnership, or government entity. In most cases, businesses must be served through a registered agent or officer. To find out if an Illinois business has a registered agent, look up the business on the Illinois Secretary of State’s website. Lawsuits against the government have special rules, and you may want to talk to a lawyer.
In some limited situations, the judge may allow special types of service, such as electronic service or service by publication. Learn more about these options down below.
After the sheriff or process server delivers your court papers, they will complete a Proof of Service of Summons. Some sheriffs or process servers may use their own version of this form, called a certificate of service or a sworn statement.
The sheriff or process server will either file the completed form with the circuit court clerk or return it to you. If it is returned to you, file it with the circuit court clerk as soon as possible.
If you do not receive a completed Proof of Service of Summons form, you can contact the circuit court clerk to ask whether it was filed and how to get a copy.
If the sheriff or process server was not able to serve the other party, find out why. You may need to fill out and file a new Summons , called an “alias summons,” and try again. There may be an extra fee to issue an alias summons.
Other ways to serve a Summons
In some limited situations, a judge may allow you to serve a Summons in non-traditional ways. These methods are uncommon, are usually a last resort, and can be used only with a judge’s permission.
Service by publication in a newspaper
Service by publication means publishing a notice in a newspaper in the area where the case was filed.
Before you can serve someone this way, you must file:
- A Motion for Leave to Serve by Publication, and
- An Affidavit for Service by Publication.

The plaintiff or their lawyer still must send notice by mail to the defendant's home address within 10 days of publication.
When the plaintiff goes to court on the date of their motion, they need to show the judge that the sheriff or the special process server tried but was unable to serve the other party.
Important: If you serve someone by publication, the court may limit what you can ask for. For example, you usually cannot get a money judgment against someone who was served by publication. In a divorce case, you may be able to get the divorce, but not orders like child support.
Service by special order of the judge
If it is not practical to serve the other party using the usual methods, a judge may allow electronic service. The judge must be convinced that the other party can receive and read the documents electronically.
You must ask the judge for permission before serving someone electronically.
To do this, file a motion with the court. In your motion, explain:
- How you tried to serve the other party using the usual methods
- Why those methods did not work or are not practical
- How you want to serve them (email, text, or social media)
- Why you believe the other party will receive and read the documents
The judge may set a hearing. If the judge approves, they will issue an order explaining how to serve the other party, for example through:
- Direct message on social media (if the person has an active account)
- Text message
If you are given permission to serve the Summons electronically, you must attach the Summons, Complaint, and any other required documents. Your message must say:
“Important information - You have been sued. Read all of the documents attached to this message. To participate in the case, you must follow the instructions listed in the attached summons. If you do not, the court may decide the case without hearing from you, and you could lose the case.”
You must also mail a copy of the Summons to the other party’s last known address. A Proof of Service of Summons must be filed showing that the documents were sent electronically.
Small Claims cases: service by certified or registered mail
In small claims cases, you can ask the circuit court clerk to serve the other party by certified or registered mail. Only the circuit court clerk can mail the Small Claims Summons and Small Claims Complaint; you cannot do it yourself.
If you think the other party will not sign the receipt (green card), this may not be a good option. In that case, consider using the sheriff or a process server instead. If you are suing more than one person, you must complete a separate Small Claims Summons for each one.
