Mo. R. Civ. P. 51.14. — Jurisdiction of Judge and Court in Civil Actions Removed

(a) Following a change of venue, for any reason, to a county outside the circuit from which venue was changed, the case shall be handled by a judge regularly appointed to hear cases in the new circuit, unless a judge is otherwise assigned to hear the case as authorized by article V, §§ 6 or 15 of the constitution.

(b) The court to which any civil actions shall be transferred by change of venue shall have jurisdiction to hear and determine the same, and shall proceed to final judgment and execution therein, although such civil action would not otherwise be cognizable in such court.
