Wisconsin Statutes Civil Procedure (Ch. 799 to 847) § 815.63. Sheriff's deed; writ of assistance

Whenever title has been perfected to any real estate sold on execution, or to any part or interest in the real estate, and the defendant in execution, or any other person claiming under the defendant by title accruing subsequently to the entry of the judgment in the judgment and lien docket upon which the judgment was issued, shall be in possession of that real estate or part or interest in that real estate, and, upon demand of the person in whom the title has been perfected, refuses to surrender the possession, the person may apply to the court from which the execution issued, by verified petition, for a writ of assistance to obtain possession. A copy of this petition, with a notice of the time and place when and where the petition will be presented, shall be served upon the person against whom the writ is issued at least 10 days before the petition is presented. The petition may be served as a summons in an action in the circuit court. The court may direct the writ to issue, and the writ shall be executed and return made in the same manner as upon a sale upon a judgment for foreclosure of a mortgage.
