Wis. Stat. § 815.15
If the judgment creditor dies before satisfaction of the judgment, an execution may be issued by the judgment creditor's attorney of record in the name of the decedent or in the name of the judgment creditor's personal representative. Before an execution shall issue in the name of a personal representative, the personal representative shall file with the clerk a copy of the letters testamentary or other letters authorizing the administration of the decedent's estate, which the clerk shall file with the other papers in the action or proceeding. The clerk shall also enter at the foot of the judgment, in the judgment record, the fact of the death of the judgment creditor and the name and date of appointment of the personal representative. The moneys collected on the judgment shall be paid to the judgment creditor's personal representative, but if there is no personal representative, the moneys collected on the judgment shall be paid to the clerk of the court.
