Wisconsin Statutes Civil Procedure (Ch. 799 to 847) § 815.48. Execution sale; creditors may acquire title of preceding creditor

(1) By paying to such first creditor, the first creditor's personal representatives or assigns the sum which the first creditor paid to acquire such title, together with interest thereon from the time of the first creditor's payment.

(2) If the judgment or mortgage by virtue of which the first creditor acquired the title of the original purchaser be prior to the judgment or mortgage of such 2nd creditor and is still a lien as to such 2nd creditor the 2nd creditor shall also pay to such first creditor the amount due on the first creditor's judgment or mortgage.

(3) In the same manner any third or other creditor who might have acquired the title of the original purchaser may become a purchaser thereof from the second, third or other creditor who may have become such purchaser from any other creditor, upon the terms and conditions before specified in this section.

(4) If the original purchaser of any premises shall also be a creditor of the defendant against whom the execution issued, and as such might acquire the title of any purchaser according to the preceding provisions, the original purchaser may avail himself or herself of his or her judgment or mortgage, in the manner and on the terms prescribed, to acquire the title which any creditor may have obtained.

(5) But the judgment creditor, under whose execution the real estate was sold cannot acquire the title of the original purchaser or of any creditor to the premises so sold by virtue of the judgment on which such execution issued.
