Missouri Revised Statutes Title X. Taxation and Revenue § 137.250. List lost or destroyed--new assessment to be made

1. If from any cause the assessor's books, either before or after the taxes are extended thereon, and the assessment list taken and returned by the assessor of any county to the county commission are lost or destroyed, the assessor shall immediately make another assessment of the property for the year for which the books and lists were made. The assessment shall be made and certified under the same conditions, rules and regulations, as nearly as may be under the circumstances, as provided by law for the assessment in the first instance, and the assessor and county clerk shall receive the same pay for their services that is allowed by law for making the assessment and extending the taxes in the first instance. The assessment and tax books shall have the same validity and effect as the original assessment and tax books.

2. In the event that the assessment is not completed until after the adjournment of the county boards of equalization, the presiding commissioner of the county commission shall immediately convene the county board of equalization by causing notice of the time of the special meeting to be served on each member of the board not less than three days prior to the date fixed by him for the meeting. The board, when assembled, shall equalize the valuations of property in the new assessment, in the same manner as is provided by law for the regular meetings of the board.
