Getting served with divorce papers in Illinois usually takes anywhere from a day or two to several weeks after the petition is filed. A private process server often finishes the job within a week. A county sheriff’s office may need two to four weeks or longer. If the respondent agrees to accept the case voluntarily, service can be skipped entirely and the step takes no time at all.
Timeline by Service Method
Illinois gives the petitioner more than one way to deliver the summons and petition, and the choice drives the timeline more than anything else.
Private Process Server: A Few Days to a Week
A licensed private process server typically makes the first delivery attempt within one to three days of being hired and can often complete service within a week. Process servers keep more flexible schedules than sheriff’s deputies, including evenings and weekends, which helps when the respondent works irregular hours. Fees generally run from $50 to $150, depending on the complexity of the case and how many attempts are needed.
County Sheriff: Two to Four Weeks
Sheriff service is usually the cheapest option and the slowest. The petitioner provides the documents and the respondent’s address to the sheriff’s office, and a deputy handles the delivery. Depending on county caseload and staffing, the first attempt might not happen for two weeks or more. In busier counties, the full process can stretch to three or four weeks. Fees vary by county but generally run between $50 and $75, sometimes with added mileage charges. Deputies handle civil process alongside their other duties, and divorce papers are rarely a priority.
Entry of Appearance: Same Day Possible
If the respondent already knows about the divorce and is willing to participate, they can file an Entry of Appearance with the court. This is a written acknowledgment that waives the need for a sheriff or process server to deliver anything.119th Judicial Circuit Court, IL. Dissolution of Marriage/Divorce For cooperative divorces, this is the fastest path. The timeline depends entirely on how quickly the respondent signs and files the form, which can happen the same day the petition is filed.
What Slows Service Down
The most common reason service drags on is a bad address. If the server shows up and the respondent does not live or work there, everything stops until the petitioner provides an updated location. Tracking down a correct address can take days or weeks, especially if the respondent has moved recently.
A respondent who is actively dodging service creates a bigger problem. Someone who refuses to answer the door, changes their routine, or leaves town can frustrate attempts for weeks. Experienced process servers know how to work around evasion, but it still adds time and cost. A respondent who travels frequently for work or keeps an unpredictable schedule causes similar delays, even without any intent to avoid service.
One thing that does not have to slow service down: trying one method before another. Illinois law treats personal delivery and abode service (leaving the papers at the respondent’s home with any resident at least 13 years old, then mailing a copy) as co-equal options.2Illinois General Assembly. Illinois Code 735 ILCS 5/2-203 – Service on Individuals A server does not have to exhaust personal delivery first.
When the Respondent Lives Out of State
If the respondent lives outside Illinois, the petitioner can still have them personally served in the other state. Illinois law gives out-of-state personal service the same legal weight as service within Illinois.3Illinois General Assembly. Illinois Code 735 ILCS 5/2-209 – Act Submitting to Jurisdiction, Process The logistics take longer. The petitioner typically needs to hire a process server in the respondent’s state, which adds coordination time and often higher costs. If the respondent’s out-of-state location is unknown, alternative service or publication may be necessary.
When Standard Service Fails
If personal and abode service prove impractical despite genuine effort, Illinois law offers two further options. Both require court permission and documentation of what has already been tried, so both add time.
Court-Ordered Alternative Service
The petitioner can ask the court for an order allowing service through unconventional means, such as email, text message, or a direct message on social media. The motion must include a supporting affidavit explaining what steps were taken to locate and serve the respondent, why standard methods did not work, and why the petitioner believes the respondent actually uses the specific account being proposed for service.4State of Illinois Office of the Illinois Courts. Illinois Supreme Court Reinforces Service of Summons Allowable via Social Media, Text and Email A copy must also be mailed to the respondent’s last known home address. The court has broad discretion to approve any delivery method it considers consistent with due process.5Illinois General Assembly. Illinois Code 735 ILCS 5/2-203.1 – Service on Individuals, Alternative Methods Preparing the motion and waiting for a ruling typically adds a week or two before service can even be attempted.
Service by Publication
As a last resort, the court can authorize publishing a notice in a newspaper. The petitioner must first file a sworn affidavit showing that the respondent has left the state, cannot be found after a diligent search, or is hiding so that normal service is impossible. If the judge agrees, the clerk arranges for a legal notice to be published in a newspaper circulated in the county where the case is pending, and must also mail a copy to the respondent’s last known address within 10 days of the first publication.6Illinois General Assembly. Illinois Code 735 ILCS 5/2-206 – Service by Publication, Affidavit, Mailing, Certificate The notice must run for three consecutive weeks. Between court filings, the publication schedule, and the required waiting period, service by publication adds at least a month to the overall timeline and often more. It is also the weakest form of service and limits what the court can order regarding property division and support.
The 30-Day Clock After Service
Service is only the first deadline. Once the respondent is served, they have 30 days from the date of service to file an Entry of Appearance and respond to the petition. The 30-day window does not include the day of service itself.119th Judicial Circuit Court, IL. Dissolution of Marriage/Divorce
If the respondent does nothing within those 30 days, the petitioner can ask the court to enter a default order. A default means the respondent has forfeited the right to participate in the case unless the court decides otherwise. The divorce does not end automatically at that point. The petitioner still has to attend a prove-up hearing to present evidence supporting the requests in the petition, but the respondent has no say in the outcome. Courts can set aside a default within 30 days of its entry if the respondent shows good cause, but waiting is a risky strategy that rarely works out well.
