Eligibility is limited, and this is the provision people are surprised by. Delaware's section 802 provides that "only individuals whose registration of a security shows sole ownership by 1 individual or multiple ownership by 2 or more with right of survivorship, rather than as tenants in common, may obtain registration in beneficiary form." So two people who hold an account as tenants in common cannot use it at all. The same section adds that multiple owners of a security registered in beneficiary form hold as joint tenants with right of survivorship, as tenants by the entireties, or as owners of community property held in survivorship form.
Nothing happens while the owner is alive, and the owner keeps complete control. Section 806: "the designation of a TOD beneficiary on a registration in beneficiary form has no effect on ownership until the owner's death. A registration … may be canceled or changed at any time by the sole owner or all then surviving owners without the consent of the beneficiary." The beneficiary has no interest to assign, no say in how the account is invested, and no right to be told they were named or unnamed.
It is not a will, and the reason is contractual rather than probate law. Section 809(a) provides that the transfer "is effective by reason of the contract regarding the registration between the owner and the registering entity and this chapter and is not testamentary." That is why it works outside probate. It is also why section 803 offers a form of cross-state comfort: a registration governed by the law of a jurisdiction where the act is not in force "is nevertheless presumed to be valid and authorized as a matter of contract law."
It does not defeat creditors. Section 809(b): "this chapter does not limit the rights of creditors of security owners against beneficiaries and other transferees under other laws of this State." Avoiding probate and avoiding debts are two different things, and this mechanism does only the first.
Two traps in section 807 that a reader is genuinely likely to hit. First, where more than one beneficiary survives, they "hold their interests as tenants in common" until the security is divided — so a TOD registration creates no survivorship among the beneficiaries, and the death of one of them after the owner does not send their share to the others. Second, and more consequential: "if no beneficiary survives the death of all owners, the security belongs to the estate of the deceased sole owner or the estate of the last to die of all multiple owners." A designation naming one person, never updated, produces exactly the probate the registration was set up to avoid.
Section 810 supplies the fix, but only if the firm offers it and the owner asks: a registering entity's terms may provide for "designating primary and contingent beneficiaries and substituting a named beneficiary's descendants to take in the place of the named beneficiary in the event of the beneficiary's death", which "may be indicated by appending to the name of the primary beneficiary the letters LDPS, standing for 'lineal descendants per stirpes'." Without that, a named beneficiary who dies first simply drops out.
No firm has to offer it. Section 808(a): "a registering entity is not required to offer or to accept a request for security registration in beneficiary form." Where a firm does accept one, section 808(c) discharges it from claims by the estate, creditors, heirs or devisees if it registers the transfer in good faith reliance on the registration, the chapter and the information given to it — and that protection stops once the entity has received written notice from a claimant objecting to the transfer.
Transfer on death and pay on death, on a securities registration, are the same thing. Section 805 permits either label. The real boundary against a payable-on-death account is the regime, not the wording: a payable-on-death account is a deposit account at a bank, governed for insurance purposes by the federal deposit rules, while a transfer on death registration is a securities registration under this uniform act. Different law, different institution, same effect at death.
