Mo. Rev. Stat. § 426.220
All appeals allowed by virtue of section 426.210 shall be taken and made by the appellant, or someone for him, making and filing an affidavit that the appeal is not taken for vexation or delay, but because affiant believes that appellant is prejudiced by the decision appealed from, and by giving bond to the state of Missouri in such sum as the assignee may require, and with such sureties as he may approve, conditioned that appellant will prosecute his appeal with due diligence, and pay all cost thereon awarded against appellant. If judgment for costs be rendered against appellant, it shall be against him and his sureties on the bond. In all other respects appeals shall be taken, certified and proceeded with in the same manner as applications for a trial de novo from judgments of associate circuit judges.
