Section 6-306
The designation of a transfer on death beneficiary on a registration in beneficiary form shall have no effect on ownership until the owner's death. A registration of a security in beneficiary form may be canceled or changed at any time by the sole owner or all surviving owners without the consent of the beneficiary.
Comment
This section simply affirms the right of a sole owner, or the right of all multiple owners, to end a TOD beneficiary registration without the assent of the beneficiary. The section says nothing about how a TOD beneficiary designation may be canceled, meaning that the registering entity's terms and conditions, if any, may be relevant. See Section 6-310. If the terms and conditions have nothing on the point, cancellation of a beneficiary designation presumably would be effected by a reregistration showing a different beneficiary or omitting reference to a TOD beneficiary.
