Mo. Rev. Stat. § 534.350: Execution — when issued and levied.

The judge rendering judgment in any such cause may issue execution at any time after judgment, but such execution shall not be levied until after the expiration of the time allowed for the taking of an appeal, except execution for the purpose of restoring possession shall be issued no sooner than ten days after the judgment. However, the execution for purposes of restoring possession shall be stayed pending an appeal if the losing party posts an appeal bond.
