A defining characteristic of joint tenants with rights of survivorship (JTWROS) is that when one owner dies, the deceased owner’s interest passes automatically to the surviving owner(s) by operation of law. Because ownership transfers directly to the survivors, the assets in a JTWROS account are generally not subject to probate with respect to the deceased owner’s interest. That is why C is correct. This feature is often a key motivation for choosing JTWROS registration: it can simplify transfer of assets at death and provide continuity of account ownership.

Choice A is incorrect because realized gains in a taxable account are generally taxable regardless of registration type; JTWROS does not create a special exemption from taxation on realized gains. Choice B is incorrect because JTWROS is not limited to two owners; while many joint accounts have two owners, JTWROS can exist with multiple joint tenants depending on firm policy and state law. Choice D is incorrect because required minimum distributions (RMDs) apply to certain retirement accounts (like traditional IRAs and qualified plans), not to standard taxable joint brokerage registrations. JTWROS is an ownership/registration form, not a retirement account type.

For SIE purposes, know the core registration effects:

JTWROS: survivorship feature, bypasses probate for the deceased owner’s share.

Tenants in common (TIC): no survivorship; decedent’s share passes via will/estate (probate).

This question tests those basic estate-transfer and account registration distinctions that matter in customer account setup and expectations.
