Assignee and nominee definitions clarify transferee rights and nominee's representative role in assignments and securities registration. The document defines assignee as the transferee who acquires assignor's rights-either by factual assignment or by operation of law-and explains assignment as the transfer of all or part of property, rights, or interests, including negotiable instruments and contractual rights. It defines nominee as a limited representative or custodian designated to act for another, often used in securities registration to hold title in street name while the beneficial ownership remains with the actual owner.
