Wisconsin Proof of Warship (Informal and Formal Administration) is a legal procedure used to determine the rightful heirs of an estate when a person dies without a will. The process is handled by the probate court in the county where the deceased lived. Informal Administration: An informal administration is an expedited process that is used when the estate is small and there are no disputes between the heirs. The court will appoint an administrator or family member to handle the distribution of assets. The administrator will present a list of the heirs to the court, who will then review the list and issue an order of warship. Formal Administration: A formal administration is used when the estate is large or there are disagreements among the heirs regarding the distribution of assets. The court will appoint an administrator to handle the process and hold a hearing to determine the rightful heirs. The administrator will present evidence to the court, such as proof of relationship, and the court will make a decision based on the evidence. The heirs will then be issued a formal order of warship.
