Good Delivery

The status of a security traded on an exchange when it meets a set of requirements for being in proper form for transfer of title to the buyer.

Investopedia Says:
This term, when applied to a security, represents the security certificate's readiness to be transferred to the purchaser "on good delivery". If this readiness is not achieved, the transaction cannot be settled. For example, if a certificate has a share transfer restriction on it, the certificate would not be deemed good delivery.

Securities industry designation meaning that a certificate has the necessary endorsements and meets all other requirements (signature guarantee, proper denomination, and other qualifications), so that title can be transferred by delivery to the buying broker, who is then obligated to accept it. Exceptions constitute bad delivery. See also Delivery Date.
