2005 Missouri Revised Statutes - § 510.190. — Right of trial by jury--waiver.

510.190. 1. The right of trial by jury as declared by the constitution or as given by a statute shall be preserved to the parties inviolate. In particular, any issue as to whether a release, composition, or discharge of plaintiff's original claim was fraudulently or otherwise wrongfully procured shall be tried by jury unless waived.

2. Parties shall be deemed to have waived trial by jury:

(1) By failing to appear at the trial;

(2) By filing with the clerk written consent in person or by attorney;

(3) By oral consent in court, entered on the minutes;

(4) By entering into trial before the court without objection.

3. In actions against the state when a statute provides for trial without a jury, the court, with the consent of both parties, may order a trial with a jury whose verdict has the same effect as if trial by jury had been a matter of right.

4. In actions where an infant or a mentally incapacitated person is a party and where an infant or mentally incapacitated person is represented by a legal representative, trial by jury shall be deemed to be waived under the circumstances set forth in subsection 2.
