Whenever a security issued by a corporation organized under the laws of the Commonwealth is registered in the names of two or more persons as joint tenants with right of survivorship or in the names of persons married to each other as tenants by the entireties with right of survivorship and one of such persons dies, such corporation and any transfer agent of such corporation shall, upon receipt of evidence of death, be entitled to treat the survivor or survivors as the owner or owners of such security for all purposes and to cause such security to be registered in the name of such survivor or survivors regardless of any claim of right through the decedent or by his personal representative, unless such registration is enjoined prior to its effectuation by a court of competent jurisdiction.
