Wisconsin Statutes Taxation (Ch. 70 to 79) § 72.27. Jurisdiction of circuit court

(1) Residents. The circuit court for the county of which the decedent died a resident has jurisdiction to hear and determine all questions arising under this chapter and to do any act authorized by a circuit court in other matters or proceedings coming within its jurisdiction. If 2 or more courts are entitled to exercise jurisdiction, the court first acquiring it retains exclusive jurisdiction.

(2) Nonresidents. The circuit court of Dane County has jurisdiction to hear and determine all questions relating to the determination and adjustment of the tax imposed by this chapter, if a tax appears due because of the death of a nonresident decedent and in which it does not otherwise appear necessary for regular administration. If a nonresident dies possessed of real or tangible personal property located within this state, the circuit court of the county in which the property is located shall have concurrent jurisdiction with the circuit court for Dane County.
