I would commend very highly The Law of Property 3rd ed 2021 by Michael Bridge and others. It deals comprehensively with the creation transfer and protection of legal, equitable and security interests in personal property, goods, chattels, things in action, equity and debt securities, other documentary intangibles. It examines the rules for outright and settled gifts of such items.
There is also a shorter version by the author alone which is less expensive, Personal Property Law 4th ed 2015.
Even so I was not able to find an answer to my query at Giving shares within the NRB
to which no one was able to reply.
