Illinois COMPLaINT-DETINUE is a legal action available in the state of Illinois. It is a hybrid of a complaint and a writ of retinue, which is used to recover personal property. The action is civil in nature and is often used when someone has an immediate need for their property, like when a tenant needs to recover a security deposit. There are two types of Illinois COMPLaINT-DETINUE: an action for damages and an action for repletion. An action for damages seeks money damages for the unjustified withholding of property, while an action for repletion seeks the return of specific property.
