Section 8-304 - Endorsement(a) An endorsement may be in blank or special. An endorsement in blank includes an endorsement to bearer. A special endorsement specifies to whom a security is to be transferred or who has power to transfer it. A holder may convert a blank endorsement to a special endorsement.(b) An endorsement purporting to be only of part of a security certificate representing units intended by the issuer to be separately transferable is effective to the extent of the endorsement.(c) An endorsement, whether special or in blank, does not constitute a transfer until delivery of the certificate on which it appears or, if the endorsement is on a separate document, until delivery of both the document and the certificate.(d) If a security certificate in registered form has been delivered to a purchaser without a necessary endorsement, the purchaser may become a protected purchaser only when the endorsement is supplied. However, against a transferor, a transfer is complete upon delivery and the purchaser has a specifically enforceable right to have any necessary endorsement supplied.(e) An endorsement of a security certificate in bearer form may give notice of an adverse claim to the certificate, but it does not otherwise affect a right to registration that the holder possesses.(f) Unless otherwise agreed, a person making an endorsement assumes only the obligations provided in Section 8-108 and not an obligation that the security will be honored by the issuer.5A Del.
