“Certificated security" means a security that is represented by a certificate. (COMM 8102(a)(4)) The interest of a debtor in a certificated security may be reached by a creditor only by actual seizure of the security certificate by the officer making the levy. However, a certificated security for which the certificate has been surrendered to the issuer may be reached by a creditor by legal process upon the issuer. (COMM 8112(a))
