Mo. Rev. Stat. § 271.120

No associate circuit judge shall allow any person, not a householder, to post any stray before him, without first filing with such associate circuit judge the bond required by law. And when any person, not a householder, shall appear before an associate circuit judge to post any stray, and shall fail or refuse to give the required bond, such associate circuit judge shall immediately appoint some other person, qualified by law, to take charge and post said stray. At the time of posting, the associate circuit judge shall deliver to every taker-up a written or printed statement of the duties required by law to be performed by such taker-up.
