Mo. Rev. Stat. § 400.8-406: Obligation to notify issuer of lost, destroyed or wrongfully taken security certificate.

If a security certificate has been lost, apparently destroyed or wrongfully taken, and the owner fails to notify the issuer of that fact within a reasonable time after the owner has notice of it and the issuer registers a transfer of the security before receiving notification, the owner may not assert against the issuer a claim for registering the transfer under section 400.8-404 or a claim to a new security certificate under section 400.8-405.
