If your renter cannot be found or is avoiding service, you can file a motion to ask the judge to let you do service by posting. If the judge agrees, you can post the notice on the tenant's door and mail it to them.
You first have to file a motion with the court asking them to let you do this. You must attach an affidavit that says the tenant:
- Does not live in Illinois;
- Has left Illinois;
- Cannot be found; or
- Is hiding from service.
In Cook County, you can use the form on the Cook County Clerk of Court's website.
Note: You cannot get a money judgment from a tenant you serve by mail. This means if your renter will not pay rent, you cannot get the judge to order the tenant to pay you money for unpaid rent or damages to your property if you do not serve the renter with proper notice.
