The filing fee is the number everyone quotes. It is usually less than half the bill. Pick your county and this adds the sheriff's service charge and the cost of executing the order — using only figures we have read off a published schedule.
Leave attorney fees at zero if you are filing on your own. Typical Illinois eviction representation runs several hundred to a few thousand dollars depending on whether the case is contested — but we do not publish a figure for it, because it is not a published fee.
Three things are worth understanding before you use this number for anything.
The sheriff is a separate bill from the court. The clerk's filing fee and the sheriff's service fee are set by different offices under different authority. Across the Illinois counties we have verified, filing fees vary by about 27% outside Cook County — but sheriff service fees vary by a factor of three, and eviction enforcement by a factor of five. The sheriff line is where county-to-county surprise lives.
Enforcement is billed differently in different counties. Some charge a flat fee to execute the order. Others bill an hourly standby rate, which means a difficult eviction costs more than an easy one and you cannot know in advance. Where we know the billing structure, the county page says so.
A judgment is not the same as being paid. Getting possession back and collecting unpaid rent are separate problems, and the second one is usually the harder one.
