Illinois Order Declaring Warship is a document issued by a probate court in the state of Illinois to formally declare who an individual's legal heirs are. This document is typically used when an individual dies without leaving a will, and the court must determine who the proper heirs are. There are two types of Illinois Order Declaring Warship: the Formal Order and the Informal Order. The Formal Order is issued after a formal hearing to determine the heirs and is legally binding. The Informal Order is issued by the court without a formal hearing and is typically used when it is not necessary to have a formal hearing to determine the heirs. Both types of Order Declaring Warship are necessary to transfer assets and other property to the heirs of the deceased.
