An Illinois Order Declaring Warship is a legal document issued by the court in the state of Illinois to determine the rightful heirs of a deceased person's estate. This document is typically used when a person passes away without a will or when there is a dispute over who should inherit the estate. There are three different types of Illinois Order Declaring Warship: 1) An Order of Warship, which is used to identify the heirs of an intestate decedent; 2) An Order of Descent, which is used to establish the chain of descent of an inherited property; and 3) An Order of Distribution, which is used to determine who will receive a share of the estate. In each case, the court will weigh various factors, including family relationships, marital status, and financial contributions, before determining who will inherit the estate.
