Jointly held property.

A person, other than the obligor, who holds a joint interest in property levied against under this section may request a hearing, as provided in subs. (5) (d) 6m., (6) (b) 3m. or (7) (b) 1. d., to determine the proportion of the value of the property that is attributable to his or her net contribution to the property. If a hearing is requested under this subsection, the court or circuit court commissioner shall schedule a hearing within 10 days after receiving the request. The hearing shall be limited to determining the proportion of the value of the property that is attributable to the person’s net contribution to the property. If more than one person requests a hearing under this subsection, or if the obligor requests a hearing under sub. (5) (f), (6) (c) or (7) (c), with respect to the same property, the court or circuit court commissioner may schedule the hearings together. The person requesting the hearing shall have the burden of proving his or her net contribution by clear and convincing evidence. If the court determines that a portion of the jointly held property is attributable to the contributions of the person, the court shall direct the department or the county child support agency to pay the person, from the net balance of the jointly held account or the net proceeds of the sale of the jointly held real or personal property, the proportion of the gross value of the account or real or personal property that is attributable to that person. If a circuit court commissioner conducts the hearing under this subsection, the person may, within 15 business days after the date that the circuit court commissioner makes his or her decision, request review of the decision by the court with jurisdiction over the action.
