Mo. Rev. Stat. § 521.820
If such objections shall be overruled by the court, such indemnification bond and the security therein shall be deemed good and sufficient so far as the liability of such sheriff or other officer aforesaid is concerned; but if such security shall be adjudged insufficient the court may, on motion of said claimant or sheriff or other officer aforesaid, order an additional indemnification bond to be given and filed in the suit within a certain time fixed by the court, and if such additional bond shall be given, and the security therein be approved of by such court, or the judge thereof, then such sheriff or other officer aforesaid shall be entitled to the protection of this law, the same as if he had taken good and sufficient indemnification bond.
