Wis. Stat. § 860.13
The personal representative may not be interested as a purchaser, mortgagee, or lessee of any property in the estate unless the purchase, mortgage, or lease is made with the written consent of the persons interested and of the guardian ad litem for minors and individuals adjudicated incompetent or with the approval of the court after petition and hearing on notice given under s. 879.03 to all persons interested, or unless the will of the decedent specifically authorizes the personal representative to be interested as a purchaser, mortgagee, or lessee.
Wis. Stat. § 860.13
This section gives a circuit court authority to approve a sale of estate property to a personal representative, but it does not list any criteria for the court to apply in making that decision. When a statute grants a circuit court broad authority to act, without constraining the court's authority in any way, it makes sense to review the court's decision for an erroneous exercise of discretion. Piette v. Horn, 2015 WI App 41, 361 Wis. 2d 484, 864 N.W.2d 900, 14-1688. The circuit court appropriately considered the following factors when approving a sale subject to this section: 1) the likelihood that the sale price would be higher than the personal representative's offer if the property were offered for public sale, balanced against the attendant delay and increased holding costs that would result from publicly listing the property for sale; 2) the relative interests of the parties in the proceeds of the sale; 3) the property's highest and best use; 4) the property's physical characteristics and improvements; 5) the various appraisals, and the expertise and credibility of the appraisers; and 6) the lack of evidence of self-dealing by the personal representative. Piette v. Horn, 2015 WI App 41, 361 Wis. 2d 484, 864 N.W.2d 900, 14-1688.
