Mo. Rev. Stat. § 88.033
All parties interested shall take notice of the filing of said report, and any owner of any lot, tract or parcel of land assessed may, within ten days after the filing of said report, file his written exception to said report, asking that the same be set aside and, if the judge shall find that such assessment was not properly made, or that injustice was done in the making of such assessment, he shall set aside the report of the commissioners and appoint new commissioners, who shall proceed in the manner provided for the first commissioners, and so on until a fair and proper determination of the allowance of damages and assessment of benefits has been made and reported. Whenever no exceptions are filed within the time limited, or whenever the judge shall find that the commissioners have fairly and properly discharged their duties and reported their action, he shall make an order confirming the assessment as reported, which shall be final as to the assessment of benefits.
