An Illinois Petition to Terminate Independent Administration is a legal document that can be filed in the state of Illinois to terminate an independent executor's authority to manage a decedent's estate. This document is typically filed when an independent executor is no longer able to fulfill the duties of the job or if the beneficiaries of the estate disagree with the independent executor's decisions and want to take control of the estate themselves. There are two types of Illinois Petitions to Terminate Independent Administration: one to terminate an independent executor's authority to manage an estate and one to terminate an independent administrator's authority to manage an estate. Both documents must be filed in the Circuit Court of the county in which the estate is based.
