Missouri Revised Statutes Title X. Taxation and Revenue § 141.130. Sale of property--approval by court--acceptance, when

1. Whenever a sale under execution on a tax judgment shall be had, the sheriff shall announce that such sale is subject to the approval of the court, and the sheriff shall report the sale and the amount of the bid to the court in which judgment was rendered, and the court shall appoint two disinterested and competent appraisers, who shall appraise the value of the property and the improvements thereon.

2. If the amount bid by the purchaser at the execution sale shall exceed fifty percent of the value of the property, the court shall confirm the sale, and the sheriff shall execute a deed for the property.

3. If the amount bid by the purchaser is less than fifty percent of the appraised value of the property, and the title which would be acquired by the purchaser is subject to other taxes, which are a lien superior to the lien of the taxes for which the judgment was rendered, and the combined amount of such prior liens and the amount bid by the purchaser shall exceed fifty percent of the appraised value of the property, the court shall likewise confirm the sale, and the sheriff shall execute a deed to the purchaser.

4. If the amount bid, together with prior tax liens, if any, shall be less than fifty percent of the appraised value of the property, the court may require the purchaser to increase his bid to an amount equal to fifty percent of such appraised value, and if the purchaser agrees so to do, and makes such additional payment, the sale shall be approved, and the sheriff shall execute and deliver a deed to the purchaser, but if the purchaser declines to increase his bid and make such additional payment, the sale shall be disapproved and the lien of the judgment continued, subject to the issuance of subsequent executions.
