Statewide Illinois coordination
Illinois requires a court-appointed special process server, and Cook County runs that appointment at a scale no other county matches. Downstate circuits apply the same statute with different local habits.
Assignment basics
Nothing here guarantees a service outcome; results depend on the defendant, the address, and the court's requirements.
Jurisdiction
Illinois sets who may serve, how process is delivered, and what the return has to show. The venue named in the filing decides how that record is read.
Who may serve. Illinois authorizes service by the sheriff or by a special process server appointed by the circuit court, who is not a party to the action. Appointment is per county and is verified for the case before service.
Method. Personal delivery, or abode service on a family member at least thirteen years old who lives there, followed by a mailing to the defendant’s last known address within the statutory window.
Proof. The server files an affidavit of service. Where abode service is used, both the delivery and the mailing must appear, or the service is vulnerable.
Abode service is two steps
The delivery and the mailing are separate facts, and both belong in the record. Files are built so the mailing date is provable, not inferred.Execution
One protocol, adjusted for the court, the address type and the defendant.
Case details, defendant information, service address, and documents are captured in one request.
The assignment is matched to the venue, county, and precinct responsible for that address.
Each attempt is recorded: date, time, address description, access conditions, and contact outcome.
Where personal service fails, substitute service or a diligence record for alternative service is prepared.
When service is completed, a signed, sworn affidavit of service documents the applicable recipient, date, time, location and method of service. When service is unsuccessful, a signed, sworn affidavit of non-service or due diligence documents the attempts, circumstances, findings and unsuccessful outcome. Both are executed under penalty of perjury and prepared in accordance with the applicable jurisdiction's execution and filing requirements.
Coverage
Dedicated local pages exist for the largest Illinois markets. Every other county is coordinated through the statewide desk and confirmed at intake.
Local logistics
Geography, building access, and court practice decide how an attempt is planned.
Chicago and suburban Cook run the state’s highest volume, with court calls that reward a return filed correctly the first time.
DuPage, Lake, Will and Kane each keep their own appointment practice, and downstate circuits add mailing expectations that are checked per case.
Documents
Each category is handled with the method the governing rule allows.
Service options
Standard, rush, or emergency coordination — same documentation standard.
Documented multi-attempt service with a filing-ready affidavit.
Priority dispatch and accelerated attempt scheduling.
Immediate coordination for time-critical court deadlines.
Dispatch timing does not guarantee completion. Completion depends on defendant access, address conditions, and the requirements of the issuing court. How pricing is determined
