Some defendants do not want to be found. They dodge the door, change addresses, or simply go quiet once they sense a lawsuit. Illinois law anticipates this and gives plaintiffs a path forward, but it has to be done by the book. Here is how service works when a defendant is actively avoiding it.
First, the diligent attempts
Before any shortcut, a process server is expected to make genuine, varied attempts: different days, different times, early morning and evening, and verification that the address is current. These attempts are documented, because the record of effort is what later persuades a judge that ordinary service truly was not possible.
Substitute service at the abode
If the defendant is hard to catch in person, Illinois allows abode service under 735 ILCS 5/2-203: leaving the documents at the defendant’s usual place of abode with a family member or resident who is at least 13, explaining what they are, and mailing a copy to that address. Done correctly, this completes service even if the defendant never personally takes the papers.
When personal and abode service both fail
When both are impractical, 735 ILCS 5/2-203.1 lets the plaintiff move for service by special order of court. The motion must be backed by an affidavit detailing the investigation: where the defendant was looked for, what was tried, and why normal service did not work. If the court is satisfied, it can authorize an alternative method consistent with due process, which courts increasingly allow to include email or other electronic means.
Skip tracing closes the gap
Often the problem is not avoidance but a bad address. Skip tracing finds the current location so a server can complete an ordinary serve, which is faster and cleaner than a court motion. When a defendant truly is hiding, the same investigative record supports the special-order motion.
A note on obstruction
Avoiding service is one thing. Actively obstructing an authorized server is another. Illinois treats knowingly resisting or obstructing the service of process as a criminal offense, which is worth remembering for anyone tempted to interfere.
