The personal representative or surviving spouse may petition the court for an order determining the classification of property under ch. 766, and for other equitable relief necessary for management and control of the marital property during the administration of the estate. The court may make any decree under ch. 766, including a decree that the property be titled in accordance with its classification, to assist the personal representative or surviving spouse in managing and controlling the marital property and the decedent's property other than marital property during administration of the estate. During administration, the management and control rules under s. 766.51 apply to the property of a decedent spouse which is subject to administration and to the property of the surviving spouse.
