Wisconsin Domiciliary Letters (Informal and Formal Administration) are documents issued by the Wisconsin probate court that grant authority to a person or persons to manage the assets of a deceased person. The type of letter issued depends on the size of the estate. If the estate is of small value, an informal letter of administration is issued. If the estate is larger, a formal letter of administration is issued. Both letters grant similar authority to the executor, but the formal letter is more comprehensive and gives more power to the executor. The informal letter of administration grants authority to the executor to settle the decedent's debts, manage the estate, and distribute assets to the beneficiaries. The formal letter of administration gives the executor additional authority, including the ability to sell real estate, transfer titles, and make investments. Both types of Wisconsin Domiciliary Letters are issued by the probate court and must be filed with the court.
