Mo. R. Civ. P. 77.04
At any time more than thirty days before the trial begins, a party defending against a claim may serve upon the adverse party an offer to allow judgment to be taken against the defending party for the money or property or to the effect specified in the offer, with costs then accrued. If within ten days after the service of the offer the adverse party serves written notice that the offer is accepted, either party may then file the offer and notice of acceptance together with proof of service thereof and thereupon judgment shall be entered. If the offer is not accepted within ten days it shall be deemed withdrawn and evidence thereof is not admissible. If the adverse party fails to obtain a judgment more favorable than that offered, that party shall not recover costs in the circuit court from the time of the offer but shall pay costs from that time.
