What must be done for control of uncertificated investment property?

Control of uncertificated investment property is established through an official transfer on the issuer's books to the creditor's name. This process involves the issuer recognizing the creditor as the new owner of the investment property, which effectively gives the creditor the ability to exercise rights associated with that property. The transfer is recorded in the issuer’s records, creating an official acknowledgment that the creditor has control and rights to the property.

This procedure is essential because, unlike certificated securities where possession might grant control, uncertificated investment property requires the issuer's recognition to establish control. This distinction reinforces the necessity of having the creditor’s name on the issuer’s records for the proper legal standing and to assert rights against the property.

In scenarios involving control over investment property, the other options do not achieve the requisite legal standard for control. A contract with the issuer or merely delivering possession does not automatically confer legal rights or control. Similarly, filing with the secretary of state typically pertains to security interests more broadly, rather than establishing control over specific investment property, making those options less effective in this context.
