When, in a case not otherwise provided for in this chapter, it is necessary in a proceeding to sever or set out a homestead from other real estate, the court in which such proceedings are pending may appoint three commissioners to appraise and set out such homestead who, after being sworn, shall appraise and set out such homestead as provided for setting out homesteads in case of the levy of execution, and make report of their doings to such court. Such report shall be confirmed by the court unless cause is shown to the contrary, and a record thereof shall be made in the office where a deed of such homestead is required to be recorded, which shall operate as a severance of the homestead from the other real estate.
