Possession Requirements in Illinois
Illinois requires actual, open, exclusive, continuous, and hostile possession. The claimant must claim under color of title with payment of taxes for the 7-year period.
The five elements of adverse possession must all be satisfied simultaneously throughout the statutory period. If an owner gives the occupant written permission to use the property at any point, the "hostile" element is defeated — resetting the clock entirely.

How to Remove a Squatter in Illinois
Property owners in Illinois should act quickly when an unauthorized occupant is discovered. The process depends on whether the person ever had permission to be on the property:
Trespassers (no permission ever given): Contact local law enforcement. If the person has no claim of right, police can remove them. Document the situation thoroughly.
Holdover tenants (had permission, now overstaying): 5-day notice to quit for nonpayment of rent; 10-day notice for other lease violations. Trespassers: police can remove immediately. After serving notice, if the occupant does not vacate: File an eviction action in Circuit Court. Illinois has an expedited eviction process; hearings can occur within 14–21 days of filing.
Adverse possession claimants: If the occupant asserts a legal claim to the property and has been present for a significant period, consult a real estate attorney immediately. Do not attempt self-help eviction, as this may expose you to liability.
